+# Luke's dmenu
+
+Extra stuff added to vanilla dmenu:
+
+- reads Xresources (ergo pywal compatible)
+- alpha patch, which importantly allows this build to be embedded in transparent st
+- can view color characters like emoji
+- `-P` for password mode: hide user input
+- `-r` to reject non-matching input
+- dmenu options are mouse clickable
+
+## Installation
+
+After making any config changes that you want, but `make`, `sudo make install` it.

+.RB [ \-w
+.IR windowid ]
+.P
+.BR dmenu_run " ..."
+.SH DESCRIPTION
+.B dmenu
+is a dynamic menu for X, which reads a list of newline\-separated items from
+stdin.  When the user selects an item and presses Return, their choice is printed
+to stdout and dmenu terminates.  Entering text will narrow the items to those
+matching the tokens in the input.
+.P
+.B dmenu_run
+is a script used by
+.IR dwm (1)
+which lists programs in the user's $PATH and runs the result in their $SHELL.
+.SH OPTIONS
+.TP
+.B \-b
+dmenu appears at the bottom of the screen.
+.TP
+.B \-f
+dmenu grabs the keyboard before reading stdin if not reading from a tty. This
+is faster, but will lock up X until stdin reaches end\-of\-file.
+.TP
+.B \-i
+dmenu matches menu items case insensitively.
+.TP
+.B \-P
+dmenu will not directly display the keyboard input, but instead replace it with dots. All data from stdin will be ignored.
+.TP
+.B \-r
+dmenu will reject any input which would result in no matching option left.
+.TP
+.BI \-l " lines"
+dmenu lists items vertically, with the given number of lines.
+.TP
+.BI \-m " monitor"
+dmenu is displayed on the monitor number supplied. Monitor numbers are starting
+from 0.
+.TP
+.BI \-p " prompt"
+defines the prompt to be displayed to the left of the input field.
+.TP
+.BI \-fn " font"
+defines the font or font set used.
+.TP
+.BI \-nb " color"
+defines the normal background color.
+.IR #RGB ,
+.IR #RRGGBB ,
+and X color names are supported.
+.TP
+.BI \-nf " color"
+defines the normal foreground color.
+.TP
+.BI \-sb " color"
+defines the selected background color.
+.TP
+.BI \-sf " color"
+defines the selected foreground color.
+.TP
+.B \-v
+prints version information to stdout, then exits.
+.TP
+.BI \-w " windowid"
+embed into windowid.
+.SH USAGE
+dmenu is completely controlled by the keyboard.  Items are selected using the
+arrow keys, page up, page down, home, and end.
+.TP
+.B Tab
+Copy the selected item to the input field.
+.TP
+.B Return
+Confirm selection.  Prints the selected item to stdout and exits, returning
+success.
+.TP
+.B Ctrl-Return
+Confirm selection.  Prints the selected item to stdout and continues.
+.TP
+.B Shift\-Return
+Confirm input.  Prints the input text to stdout and exits, returning success.
+.TP
+.B Escape
+Exit without selecting an item, returning failure.
+.TP
+.B Ctrl-Left
+Move cursor to the start of the current word
+.TP
+.B Ctrl-Right
+Move cursor to the end of the current word

+.SH NAME
+stest \- filter a list of files by properties
+.SH SYNOPSIS
+.B stest
+.RB [ -abcdefghlpqrsuwx ]
+.RB [ -n
+.IR file ]
+.RB [ -o
+.IR file ]
+.RI [ file ...]
+.SH DESCRIPTION
+.B stest
+takes a list of files and filters by the files' properties, analogous to
+.IR test (1).
+Files which pass all tests are printed to stdout. If no files are given, stest
+reads files from stdin.
+.SH OPTIONS
+.TP
+.B \-a
+Test hidden files.
+.TP
+.B \-b
+Test that files are block specials.
+.TP
+.B \-c
+Test that files are character specials.
+.TP
+.B \-d
+Test that files are directories.
+.TP
+.B \-e
+Test that files exist.
+.TP
+.B \-f
+Test that files are regular files.
+.TP
+.B \-g
+Test that files have their set-group-ID flag set.
+.TP
+.B \-h
+Test that files are symbolic links.
+.TP
+.B \-l
+Test the contents of a directory given as an argument.
+.TP
+.BI \-n " file"
+Test that files are newer than
+.IR file .
+.TP
+.BI \-o " file"
+Test that files are older than
+.IR file .
+.TP
+.B \-p
+Test that files are named pipes.
+.TP
+.B \-q
+No files are printed, only the exit status is returned.
+.TP
+.B \-r
+Test that files are readable.
+.TP
+.B \-s
+Test that files are not empty.
+.TP
+.B \-u
+Test that files have their set-user-ID flag set.
+.TP
+.B \-v
+Invert the sense of tests, only failing files pass.
+.TP
+.B \-w
+Test that files are writable.
+.TP
+.B \-x
+Test that files are executable.
+.SH EXIT STATUS
+.TP
+.B 0
+At least one file passed all tests.
+.TP
+.B 1
+No files passed all tests.
+.TP
+.B 2
+An error occurred.

+# Luke's build of dwm
+
+## FAQ
+
+> What are the bindings?
+
+This is suckless, mmmbud, the source code is the documentation! Check out [config.h](config.h).
+
+Okay, okay, actually I keep a readme in `larbs.mom` for my whole system, including the binds here.
+Press <kbd>super+F1</kbd> to view it in dwm (zathura is required for that binding).
+I haven't kept `man dwm`/`dwm.1` updated though. PRs welcome on that, lol.
+
+## Patches and features
+
+- [Clickable statusbar](https://dwm.suckless.org/patches/statuscmd/) with my build of [dwmblocks](https://github.com/lukesmithxyz/dwmblocks).
+- Reads [xresources](https://dwm.suckless.org/patches/xresources/) colors/variables (i.e. works with `pywal`, etc.).
+- scratchpad: Accessible with <kbd>mod+shift+enter</kbd>.
+- New layouts: bstack, fibonacci, deck, centered master and more. All bound to keys <kbd>super+(shift+)t/y/u/i</kbd>.
+- True fullscreen (<kbd>super+f</kbd>) and prevents focus shifting.
+- Windows can be made sticky (<kbd>super+s</kbd>).
+- [hide vacant tags](https://dwm.suckless.org/patches/hide_vacant_tags/) hides tags with no windows.
+- [stacker](https://dwm.suckless.org/patches/stacker/): Move windows up the stack manually (<kbd>super-K/J</kbd>).
+- [shiftview](https://dwm.suckless.org/patches/nextprev/): Cycle through tags (<kbd>super+g/;</kbd>).
+- [vanitygaps](https://dwm.suckless.org/patches/vanitygaps/): Gaps allowed across all layouts.
+- [swallow patch](https://dwm.suckless.org/patches/swallow/): if a program run from a terminal would make it inoperable, it temporarily takes its place to save space.
+
+
+## Installation for newbs
+
+```bash
+git clone https://github.com/LukeSmithxyz/dwm.git
+cd dwm
+sudo make install
+```
+
+There is also a `PKGBUILD` usable on distributions with pacman. Run `makepkg -si` instead of `sudo make install`.

+.SH NAME
+dwm \- dynamic window manager (Luke Smith <https://lukesmith.xyz>'s build)
+.SH SYNOPSIS
+.B dwm
+.RB [ \-v ]
+.SH DESCRIPTION
+dwm is a dynamic window manager for X.
+.P
+dwm "orders" windows based on recency and primacy, while dwm layouts may
+change, the most recent "master" window is shown in the most prominent
+position. There are bindings for cycling through and promoting windows to the
+master position.
+.P
+Windows are grouped by tags. Each window can be tagged with one or multiple
+tags. Selecting certain tags displays all windows with these tags.
+.P
+Each screen contains a small status bar which displays all available tags, the
+layout, the title of the focused window, and the text read from the root window
+name property, if the screen is focused. A floating window is indicated with an
+empty square and a maximised floating window is indicated with a filled square
+before the windows title.  The selected tags are indicated with a different
+color. The tags of the focused window are indicated with a filled square in the
+top left corner.  The tags which are applied to one or more windows are
+indicated with an empty square in the top left corner.
+.P
+dwm draws a small border around windows to indicate the focus state.
+.SH OPTIONS

+.B Super\-Middle click
+Toggles focused window between floating and tiled state.
+.TP
+.B Super\-Right click
+Resize focused window while dragging. Tiled windows will be toggled to the floating state.
+.SH CUSTOMIZATION
+dwm is customized by creating a custom config.h and (re)compiling the source
+code. This keeps it fast, secure and simple.
+.SH SIGNALS
+.TP
+.B SIGHUP - 1
+Restart the dwm process.
+.TP
+.B SIGTERM - 15
+Cleanly terminate the dwm process.
+.SH SEE ALSO

+.SH ISSUES
+Java applications which use the XToolkit/XAWT backend may draw grey windows
+only. The XToolkit/XAWT backend breaks ICCCM-compliance in recent JDK 1.5 and early
+JDK 1.6 versions, because it assumes a reparenting window manager. Possible workarounds
+are using JDK 1.4 (which doesn't contain the XToolkit/XAWT backend) or setting the
+environment variable
+.BR AWT_TOOLKIT=MToolkit
+(to use the older Motif backend instead) or running
+.B xprop -root -f _NET_WM_NAME 32a -set _NET_WM_NAME LG3D
+or
+.B wmname LG3D
+(to pretend that a non-reparenting window manager is running that the
+XToolkit/XAWT backend can recognize) or when using OpenJDK setting the environment variable
+.BR _JAVA_AWT_WM_NONREPARENTING=1 .
+.SH BUGS
+Send all bug reports with a patch to hackers@suckless.org.

+ *
+ * dynamic window manager is designed like any other X client as well. It is
+ * driven through handling X events. In contrast to other X clients, a window
+ * manager selects for SubstructureRedirectMask on the root window, to receive
+ * events about window (dis-)appearance. Only one X connection at a time is
+ * allowed to select for this event mask.
+ *
+ * The event handlers of dwm are organized in an array which is accessed
+ * whenever a new event has been fetched. This allows event dispatching
+ * in O(1) time.
+ *
+ * Each child of the root window is called a client, except windows which have
+ * set the override_redirect flag. Clients are organized in a linked client
+ * list on each monitor, the focus history is remembered through a stack list
+ * on each monitor. Each client contains a bit array to indicate the tags of a
+ * client.
+ *
+ * Keys and tagging rules are organized as arrays and defined in config.h.
+ *
+ * To understand everything else, start reading main().

+Capslock is a useless key in high quality space.
+It's now remapped.
+If you press it alone, it will function as escape, making vimcraft much more natural,
+but you can also hold it down and it will act as another Windows/super/mod key.
+.ITEM
+The menu button (usually between the right Alt and Ctrl) is an alternative Super/Mod button.
+This is to make one-handing on laptops easier.
+.LIST OFF
+.PP
+If you'd like to change any of these keyboard changes, you need only open and change the \f(CWremaps\fP script.
+All custom scripts in LARBS are located in \f(CW~/.local/bin/\fP.
+Actually, this should go without saying, but \fIeverything\fP here can easily be changed.
+Below in this document, there is information about where to change programs/components.
+.PP
+Additionally, while this isn't a part of the desktop environment, the default editing mode in the shell is using vi bindings.
+If you want to learn more of this, run \f(CWMod+F2\fP and type and select the option for "vi mode in shell".
+This setting can be changed if you don't like it by deleting or commenting out the contents of \f(CW~/.config/shell/inputrc\fP.
+.HEADING 2 "The Status Bar"
+.PP
+To the left, you'll see the numbers of your current workspace/tag(s).
+On the right, you'll see various system status notifiers, the date, volume, even music and local weather if possible, etc.
+Each module on the right of the statusbar is a script located in \f(CW~/.local/bin/statusbar/\fP.
+You can see what they do and modify them from there.
+I'm sure you can figure it out.
+You can also right click on the module to see what it does.
+.PP
+The program dwmblocks is what is run to generate the statusbar from those scripts.
+You can edit its config/source code in \f(CW~/.local/src/dwmblocks/\fP to tell it what scripts/commands you want it to display.
+.HEADING 3 "HiDPI and 4K Displays"
+.PP
+If you have a screen with a very high dots-per-inch, the interface, particularly the status bar at the top may be very small. To change this, you can run \f(CWxrandr --dpi 96\fP, replacing 96 with a higher number, then you can refresh the window manager in the menu at \f(CWsuper+backspace\fP. To make this change persistent after reboot, edit \f(CW~/.xprofile\fP and you will see that same command which you can change to have the dots-per-inch value you want.
+.HEADING 2 "Deeper Tutorials"
+.PP
+Press \f(CWmod+F2\fP at any time to get a menu of programs to watch videos about streaming directly from YouTube.
+You can also check the config files for programs which detail a lot of the specific bindings.
+.HEADING 1 "Key Bindings"
+.PP
+The window manager dwm abstractly orders all of your windows into a stack from most important to least based on when you last manipulated it.
+dwm is an easy to use window manager, but you should understand that it makes use of that stack layout.
+If you're not familiar, I recommend you press \f(CWMod+F2\fP and select the "dwm" option to watch my brief tutorial (note that the bindings I discuss in the video are the default dwm binds, which are different (inferior) to those here).
+.PP
+Notice also the case sensitivity of the shortcuts\c
+.FOOTNOTE
+To type capital letters, hold down the \f(CWShift\fP key\(emthat might sound like an obvious and condescending thing to tell you, but there have literally been multiple people (Boomers) who have emailed me asking how to type a capital letter since caps lock isn't enabled.

+.PP
+Dotfiles/settings files are located in \f(CW~/.config/\fP.
+.PP
+Suckless programs, dwm (the window manager), st (the terminal) and dmenu among others do not have traditional config files, but have their source code location in \f(CW~/.local/src/\fP (press \f(CWrr\fP to jump to that directory).
+There you can modify their \f(CWconfig.h\fP files or other source code, then \f(CWsudo make install\fP to reinstall.
+.PP
+vim is set to automatically recompile and install these programs whenever you save changes to any \f(CWconfig.h\fP file
+(compilation will be nearly instantaneous).
+You'll have to restart the program to see its effects obviously.
+.HEADING 1 "Frequently Asked Questions (FAQs)"
+.HEADING 2 "My keyboard isn't working as expected!"
+.PP
+As mentioned above, LARBS makes some keyboard changes with the \f(CWremaps\fP script.
+These settings may override your preferred settings, so you should open this file and comment out troublesome lines if you have issues.
+.HEADING 2 "My audio isn't working!"
+.PP
+On fresh install, the Linux audio system often mutes outputs.
+You may also need to set your preferred default output sink which you can do by the command line, or by selecting one with \f(CWpulsemixer\fP (\f(CWMod+F4\fP).
+.HEADING 2 "How do I copy and paste?"
+.PP
+Copying and pasting is always program-specific on any system.
+In most graphical programs, copy and paste will be the same as they are on Windows: \f(CWctrl-c\fP and \f(CWctrl-v\fP.
+In the Linux terminal, those binds have other more important purposes, so you can run \f(CWman st\fP to see how to copy and paste in my terminal build.
+.PP
+Additionally, I've set vim to use the clipboard as the default buffer, which means when you yank or delete something in vim, it will be in your system clipboard as well, so you can \f(CWctrl-v\fP it into your browser instance, etc. You can also paste material copied from other programs into vim with the typical vim bindings.
+.HEADING 2 "How do I change the background/wallpaper?"
+.PP
+The system will always read the file \f(CW~/.local/share/bg\fP as the wallpaper.
+The script \f(CWsetbg\fP, if run on an image will set it as the persistent background.
+When using the file manager, you can simply hover over an image name and type \f(CWb\fP and this will run \f(CWsetbg\fP.
+.HEADING 2 "How I change the colorscheme?"
+.PP
+LARBS no longer deploys Xresources by default, but check \f(CW~/.config/x11/xresources\fP for a list of color schemes you can activate or add your own. When you save the file, vim will automatically update the colorscheme. If you'd like these colors activated by default on login, there is a line in \f(CW~/.config/x11/xprofile\fP you can uncomment to allow that.
+.PP
+Or, if you want to use \f(CWwal\fP to automatically generate colorschemes from your wallpapers, just install it and \f(CWsetbg\fP will automatically detect and run it on startup and wallpaper change.
+.HEADING 2 "How do I set up my email?"
+.PP
+LARBS comes with mutt-wizard, which gives the ability to receive and send all your email and keep an offline store of it all in your terminal, without the need for browser.
+You can add email accounts by running \f(CWmw -a your@email.com\fP.
+See \f(CWman mw\fP for all the information you need about mutt-wizard.
+.PP
+Once you have successfully added your email address(es), you can open your mail with \f(CWneomutt\fP which is also bound to \f(CWMod+e\fP.
+You can sync your mail by pressing \f(CWMod+F8\fP and you can set a cronjob to sync mail every 10 minutes by running \f(CWmw -t 10\fP.
+.PP
+You may also want to install \f(CWpam-gnupg-git\fP, which can be set up to automatically unlock your GPG key on login, which will allow you avoid having put in a password to sync and send, all while keeping your password safe and encrypted on your machine.
+.HEADING 2 "How do I set up my music?"
+.PP
+By default, mpd, the music daemon assumes that \f(CW~/Music\fP is your music directory.
+This can be changed in \f(CW~/.config/mpd/mpd.conf\fP.
+When you add music to your music folder, you may have to run \f(CWmpc up\fP in the terminal to update the database.
+mpd is controlled by ncmpcpp, which is accessible by \f(CWMod+m\fP.
+.HEADING 2 "How do I update LARBS?"
+.PP
+LARBS is deployed as a git repository in your home directory.
+You can use it as such to fetch, diff and merge changes from the remote repository.
+If you don't want to do that or don't know how to use git, you can actually just rerun the script (as root) and reinstall LARBS and it will automatically update an existing install if you select the same username.
+This will overwrite the original config files though, including changes you made for them, but this is an easier brute force approach that will also install any new dependencies.
+.HEADING 1 "Important Links"
+.PP
+You can follow links via the keyboard in this pdf reader by pressing \f(CWf\fP followed by the number that appears on the desired link.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.

+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+# dwmblocks
+
+Modular status bar for dwm written in c.
+
+# Modifying blocks
+
+The statusbar is made from text output from commandline programs.  Blocks are
+added and removed by editing the config.h file.
+
+# Luke's build
+
+I have dwmblocks read my preexisting scripts
+[here in my dotfiles repo](https://github.com/LukeSmithxyz/voidrice/tree/master/.local/bin/statusbar).
+So if you want my build out of the box, download those and put them in your
+`$PATH`. I do this to avoid redundancy in LARBS, both i3 and dwm use the same
+statusbar scripts.
+
+# Signaling changes
+
+Most statusbars constantly rerun every script every several seconds to update.
+This is an option here, but a superior choice is giving your module a signal
+that you can signal to it to update on a relevant event, rather than having it
+rerun idly.
+
+For example, the audio module has the update signal 10 by default.  Thus,
+running `pkill -RTMIN+10 dwmblocks` will update it.
+
+You can also run `kill -44 $(pidof dwmblocks)` which will have the same effect,
+but is faster.  Just add 34 to your typical signal number.
+
+My volume module *never* updates on its own, instead I have this command run
+along side my volume shortcuts in dwm to only update it when relevant.
+
+Note that all modules must have different signal numbers.
+
+# Clickable modules
+
+Like i3blocks, this build allows you to build in additional actions into your
+scripts in response to click events.  See the above linked scripts for examples
+of this using the `$BLOCK_BUTTON` variable.
+
+For this feature to work, you need the appropriate patch in dwm as well. See
+[here](https://dwm.suckless.org/patches/statuscmd/).
+Credit for those patches goes to Daniel Bylinka (daniel.bylinka@gmail.com).

+
+
+Requirements
+------------
+In order to build slock you need the Xlib header files.
+
+
+Installation
+------------
+Edit config.mk to match your local setup (slock is installed into
+the /usr/local namespace by default).
+
+Afterwards enter the following command to build and install slock
+(if necessary as root):
+
+    make clean install
+
+
+Running slock
+-------------
+Simply invoke the 'slock' command. To get out of it, enter your password.

+.Sh SYNOPSIS
+.Nm
+.Op Fl v
+.Op Ar cmd Op Ar arg ...
+.Sh DESCRIPTION
+.Nm
+is a simple X screen locker.
+If provided,
+.Ar cmd
+is executed after the screen has been locked.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl v
+Print version information to stdout and exit.
+.El
+.Sh EXIT STATUS
+.Ex -std
+.Sh EXAMPLES
+$
+.Nm
+/usr/sbin/s2ram
+.Sh SECURITY CONSIDERATIONS
+To make sure a locked screen can not be bypassed by switching VTs
+or killing the X server with Ctrl+Alt+Backspace, it is recommended
+to disable both in
+.Xr xorg.conf 5
+for maximum security:
+.Bd -literal
+Section "ServerFlags"
+	Option "DontVTSwitch" "True"
+	Option "DontZap"      "True"
+EndSection
+.Ed
+.Sh CUSTOMIZATION
+.Nm
+can be customized by creating a custom config.h from config.def.h and
+(re)compiling the source code.
+This keeps it fast, secure and simple.

+# Luke's build of st - the simple (suckless) terminal
+
+The [suckless terminal (st)](https://st.suckless.org/) with some additional
+features that make it literally the best terminal emulator ever:
+
+## Unique features (using dmenu)
+
++ **follow urls** by pressing `alt-l`
++ **copy urls** in the same way with `alt-y`
++ **copy the output of commands** with `alt-o`
+
+## Bindings for
+
++ **scrollback** with `alt-↑/↓` or `alt-pageup/down` or `shift` while scrolling the
+  mouse.
++ OR **vim-bindings**: scroll up/down in history with `alt-k` and `alt-j`.
+  Faster with `alt-u`/`alt-d`.
++ **zoom/change font size**: same bindings as above, but holding down shift as
+  well. `alt-home` returns to default
++ **copy text** with `alt-c`, **paste** is `alt-v` or `shift-insert`
+
+## Pretty stuff
+
++ Compatibility with `Xresources` and `pywal` for dynamic colors.
++ Default [gruvbox](https://github.com/morhetz/gruvbox) colors otherwise.
++ Transparency/alpha, which is also adjustable from your `Xresources`.
++ Default font is system "mono" at 14pt, meaning the font will match your
+  system font.
+
+## Other st patches
+
++ Boxdraw
++ Ligatures
++ font2
++ updated to latest version 0.8.5
+
+## Installation for newbs
+
+You should have xlib header files and libharfbuzz build files installed.
+
+```
+git clone https://github.com/LukeSmithxyz/st
+cd st
+sudo make install
+```
+
+Obviously, `make` is required to build. `fontconfig` is required for the
+default build, since it asks `fontconfig` for your system monospace font. It
+might be obvious, but `libX11` and `libXft` are required as well. Chances are,
+you have all of this installed already.
+
+On OpenBSD, be sure to edit `config.mk` first and remove `-lrt` from the
+`$LIBS` before compiling.
+
+Be sure to have a composite manager (`xcompmgr`, `picom`, etc.) running if you
+want transparency.
+
+## How to configure dynamically with Xresources
+
+For many key variables, this build of `st` will look for X settings set in
+either `~/.Xdefaults` or `~/.Xresources`. You must run `xrdb` on one of these
+files to load the settings.
+
+For example, you can define your desired fonts, transparency or colors:
+
+```
+*.font:	Liberation Mono:pixelsize=12:antialias=true:autohint=true;
+*.alpha: 0.9
+*.color0: #111
+...
+```
+
+The `alpha` value (for transparency) goes from `0` (transparent) to `1`
+(opaque). There is an example `Xdefaults` file in this respository.
+
+### Colors
+
+To be clear about the color settings:
+
+- This build will use gruvbox colors by default and as a fallback.
+- If there are Xresources colors defined, those will take priority.
+- But if `wal` has run in your session, its colors will take priority.
+
+Note that when you run `wal`, it will negate the transparency of existing windows, but new windows will continue with the previously defined transparency.

+.SH DESCRIPTION
+.B st
+is a simple terminal emulator.
+.SH OPTIONS
+.TP
+.B \-a
+disable alternate screens in terminal
+.TP
+.BI \-c " class"
+defines the window class (default $TERM).
+.TP
+.BI \-f " font"
+defines the
+.I font
+to use when st is run.
+.TP
+.BI \-g " geometry"
+defines the X11 geometry string.
+The form is [=][<cols>{xX}<rows>][{+-}<xoffset>{+-}<yoffset>]. See
+.BR XParseGeometry (3)
+for further details.
+.TP
+.B \-i
+will fixate the position given with the -g option.
+.TP
+.BI \-n " name"
+defines the window instance name (default $TERM).
+.TP
+.BI \-o " iofile"
+writes all the I/O to
+.I iofile.
+This feature is useful when recording st sessions. A value of "-" means
+standard output.
+.TP
+.BI \-T " title"
+defines the window title (default 'st').
+.TP
+.BI \-t " title"
+defines the window title (default 'st').
+.TP
+.BI \-w " windowid"
+embeds st within the window identified by
+.I windowid
+.TP
+.BI \-l " line"
+use a tty
+.I line
+instead of a pseudo terminal.
+.I line
+should be a (pseudo-)serial device (e.g. /dev/ttyS0 on Linux for serial port
+0).
+When this flag is given
+remaining arguments are used as flags for
+.BR stty(1).
+By default st initializes the serial line to 8 bits, no parity, 1 stop bit
+and a 38400 baud rate. The speed is set by appending it as last argument
+(e.g. 'st -l /dev/ttyS0 115200'). Arguments before the last one are
+.BR stty(1)
+flags. If you want to set odd parity on 115200 baud use for example 'st -l
+/dev/ttyS0 parenb parodd 115200'. Set the number of bits by using for
+example 'st -l /dev/ttyS0 cs7 115200'. See
+.BR stty(1)
+for more arguments and cases.
+.TP
+.B \-v
+prints version information to stderr, then exits.
+.TP
+.BI \-e " command " [ " arguments " "... ]"
+st executes
+.I command
+instead of the shell.  If this is used it
+.B must be the last option
+on the command line, as in xterm / rxvt.
+This option is only intended for compatibility,
+and all the remaining arguments are used as a command
+even without it.
+.SH SHORTCUTS
+.TP
+.B Alt-j/k or Alt-Up/Down or Alt-Mouse Wheel
+Scroll up/down one line at a time.
+.TP
+.B Alt-u/d or Alt-Page Up/Page Down
+Scroll up/down one screen at a time.
+.TP
+.B Alt-Shift-k/j or Alt-Shift-Page Up/Page Down or Alt-Shift-Mouse Wheel
+Increase or decrease font size.
+.TP
+.B Alt-Home
+Reset to default font size.
+.TP
+.B Shift-Insert or Alt-v
+Paste from clipboard.
+.TP
+.B Alt-c
+Copy to clipboard.
+.TP
+.B Alt-p
+Paste/input primary selection.
+.TP
+.B Alt-l
+Show dmenu menu of all URLs on screen and choose one to open.
+.TP
+.B Alt-y
+Show dmenu menu of all URLs on screen and choose one to copy.
+.TP
+.B Alt-o
+Show dmenu menu of all recently run commands and copy the output of the chosen command to the clipboard.
+.I xclip
+required.
+.TP
+.B Alt-a/s
+Increase or decrease opacity/alpha value (make window more or less transparent).
+.TP
+.B Break
+Send a break in the serial line.
+Break key is obtained in PC keyboards
+pressing at the same time control and pause.
+.TP
+.B Ctrl-Print Screen
+Toggle if st should print to the
+.I iofile.
+.TP
+.B Shift-Print Screen
+Print the full screen to the
+.I iofile.
+.TP
+.B Print Screen
+Print the selection to the
+.I iofile.
+.SH CUSTOMIZATION
+.B st
+can be customized by creating a custom config.h and (re)compiling the source
+code. This keeps it fast, secure and simple.
