.SH Dotfiles (Tom Ryder)
.PP
This is my personal repository of configuration files and scripts for
\f[C]$HOME\f[], including most of the settings that migrate well between
machines.
.PP
This repository began as a simple way to share Vim and tmux
configuration, but over time a lot of scripts and shell configuration
have been added, making it into a personal suite of custom Unix tools.
.SS Installation
.IP
.nf
\f[C]
$\ git\ clone\ https://sanctum.geek.nz/code/dotfiles.git\ ~/.dotfiles
$\ cd\ ~/.dotfiles
$\ git\ submodule\ init
$\ git\ submodule\ update
$\ make
$\ make\ \-n\ install
$\ make\ install
\f[]
.fi
.PP
For the default \f[C]all\f[] target, you'll need a POSIX\-fearing
userland, including \f[C]make(1)\f[] and \f[C]m4(1)\f[].
.PP
The installation \f[C]Makefile\f[] will overwrite things standing in the
way of its installed files without backing them up, so read the output
of \f[C]make\ \-n\ install\f[] before running \f[C]make\ install\f[] to
make sure you aren't going to lose anything unexpected.
If you're still not sure, install it in a temporary directory so you can
explore:
.IP
.nf
\f[C]
$\ tmpdir=$(mktemp\ \-d)
$\ make\ install\ HOME="$tmpdir"
$\ env\ \-i\ HOME="$tmpdir"\ TERM="$TERM"\ "$SHELL"\ \-l
\f[]
.fi
.PP
The default \f[C]install\f[] target will install these targets and all
their dependencies.
Note that you don't actually have to have any of this except \f[C]sh\f[]
installed.

The \f[C]install\-login\-shell\f[] looks at your \f[C]SHELL\f[]
environment variable and tries to figure out which shell's configuration
files to install, falling back on \f[C]install\-sh\f[].
.PP
The remaining files can be installed with the other \f[C]install\-*\f[]
targets.
Try \f[C]awk\ \-f\ bin/mftl.awk\ Makefile\f[] in the project's root
directory to see a list.

.PP
The configurations for shells, GnuPG, Mutt, tmux, and Vim are the most
expansive, and most likely to be of interest.
The i3 configuration is mostly changed to make window switching behave
like Vim windows and tmux panes do, and there's a fair few resources
defined for rxvt\-unicode.
.SS Shell
.PP
My \f[C]\&.profile\f[] and other files in \f[C]sh\f[] are written in
POSIX shell script, so they should work in most \f[C]sh(1)\f[]
implementations.
Individual scripts called by \f[C]\&.profile\f[] are saved in
\f[C]\&.profile.d\f[] and iterated on login for ease of management.
Most of these boil down to exporting variables appropriate to the system
and the software it has available.
.PP
Configuration that should be sourced for all POSIX\-fearing interactive
shells is kept in \f[C]~/.shrc\f[], with subscripts read from
\f[C]~/.shrc.d\f[].
There's a shim in \f[C]~/.shinit\f[] to act as \f[C]ENV\f[].
I make an effort to target POSIX for my functions and scripts where I
can so that the same files can be loaded for all shells.
.PP
On GNU/Linux I use Bash, on BSD I use some variant of Korn Shell,
preferably \f[C]ksh93\f[] if it's available.
.PP
As I occasionally have work on very old internal systems, my Bash is
written to work with any version 2.05a or
newer (http://wiki.bash-hackers.org/scripting/bashchanges).
This is why I use older syntax for certain things such as appending
items to arrays:
.IP
.nf
\f[C]
array[${#array[\@]}]=$item
\f[]
.fi
.PP
Compare this to the much nicer syntax available since 3.1\-alpha1, which
actually works for arrays with sparse indices, unlike the above syntax:
.IP
.nf
\f[C]
array+=("$item")
\f[]

\f[C]BASH_VERSINFO\f[] appropriately.
.SS Prompt
.PP
A terminal session with my prompt looks something like this:
.IP
.nf
\f[C]
~$\ ssh\ remote
remote:~$\ cd\ .dotfiles
remote:~/.dotfiles(master+!)$\ git\ status
\ M\ README.md
M\ \ bash/bashrc.d/prompt.bash
A\ \ init
remote:~/.dotfiles(master+!)$\ foobar
foobar:\ command\ not\ found
remote:~/.dotfiles(master+!)<127>$\ sleep\ 5\ &
[1]\ 28937
remote:~/.dotfiles(master+!){1}$
\f[]
.fi
.PP
The hostname is elided if not connected via SSH.
The working directory with tilde abbreviation for \f[C]$HOME\f[] is
always shown.
The rest of the prompt expands based on context to include these
elements in this order:
.IP \[bu] 2
Whether in a Git repository if applicable, and punctuation to show
repository status including reference to upstreams at a glance.
Subversion support can also be enabled (I need it at work), in which
case a \f[C]git:\f[] or \f[C]svn:\f[] prefix is added appropriately.
.IP \[bu] 2
The number of running background jobs, if non\-zero.
.IP \[bu] 2
The exit status of the last command, if non\-zero.
.PP
You can set \f[C]PROMPT_COLOR\f[], \f[C]PROMPT_PREFIX\f[], and
\f[C]PROMPT_SUFFIX\f[] too, which all do about what you'd expect.
.PP
If you start up Bash, Korn shell, or Z shell, and it detects that it's
normally your \f[C]$SHELL\f[] is one of the other two, the prompt will
display an appropriate prefix.
.PP
This is all managed within the \f[C]prompt\f[] function.
There's some mildly hacky logic on \f[C]tput\f[] codes included such
that it should work correctly for most common terminals using both
\f[C]termcap(5)\f[] and \f[C]terminfo(5)\f[], including *BSD systems.
It's also designed to degrade gracefully for eight\-color and no\-color
terminals.
.SS Functions
.PP
If a function can be written in POSIX \f[C]sh\f[] without too much
hackery, I put it in \f[C]sh/shrc.d\f[] to be loaded by any POSIX
interactive shell.
Those include:
.IP \[bu] 2

There are a few other little tricks defined for other shells providing
non\-POSIX features, as compatibility allows:
.IP \[bu] 2
\f[C]keep()\f[] stores ad\-hoc shell functions and variables (Bash, Korn
Shell 93, Z shell).
.IP \[bu] 2
\f[C]prompt()\f[] sets up my interactive prompt (Bash, Korn Shell, Z
shell).
.IP \[bu] 2
\f[C]pushd()\f[] adds a default destination of \f[C]$HOME\f[] to the
\f[C]pushd\f[] builtin (Bash).
.IP \[bu] 2
\f[C]vared()\f[] allows interactively editing a variable with Readline,
emulating a Zsh function I like by the same name (Bash).
.IP \[bu] 2
\f[C]ver()\f[] prints the current shell's version information (Bash,
Korn Shell, Z shell).
.SS Completion
.PP
I find the \f[C]bash\-completion\f[] package a bit too heavy for my
tastes, and turn it off using a stub file installed in
\f[C]~/.config/bash_completion\f[].
The majority of the time I just want to complete paths anyway, and this
makes for a quicker startup without a lot of junk functions in my Bash
namespace.
.PP
I do make some exceptions with completions defined in
\f[C]\&.bash_completion.d\f[] files, for things I really do get tired of
typing repeatedly:
.IP \[bu] 2
Bash builtins: commands, help topics, shell options, variables, etc.
.IP \[bu] 2
\f[C]find(1)\f[]'s more portable options
.IP \[bu] 2
\f[C]ftp(1)\f[] hostnames from \f[C]~/.netrc\f[]
.IP \[bu] 2
\f[C]git(1)\f[] subcommands, remotes, branches, tags, and addable files
.IP \[bu] 2
\f[C]gpg(1)\f[] long options
.IP \[bu] 2
\f[C]make(1)\f[] targets read from a \f[C]Makefile\f[]
.IP \[bu] 2
\f[C]man(1)\f[] page titles
.IP \[bu] 2
\f[C]pass(1)\f[] entries
.IP \[bu] 2
\f[C]ssh(1)\f[] hostnames from \f[C]~/.ssh/config\f[]
.PP
For commands that pretty much always want to operate on text, such as
text file or stream editors, I exclude special file types and extensions
I know are binary.
I don't actually read the file, so this is more of a heuristic thing,
and sometimes it will get things wrong.
.PP
I also add completions for my own scripts and functions where useful.
The completions are dynamically loaded if Bash is version 4.0 or
greater.
Otherwise, they're all loaded on startup.
.SS Korn shell
.PP
These are experimental; they are mostly used to tinker with MirBSD
\f[C]mksh\f[], AT&T \f[C]ksh93\f[], and OpenBSD \f[C]pdksh\f[].
All shells in this family default to a yellow prompt if detected.
.SS Z shell
.PP
These are experimental; I do not like Z shell much at the moment.
The files started as a joke (\f[C]exec\ bash\f[]).
\f[C]zsh\f[] shells default to having a prompt colored cyan.
.SS GnuPG
.PP
The configuration for GnuPG is intended to follow RiseUp's OpenPGP best
practices (https://riseup.net/en/security/message-security/openpgp/best-practices).
The configuration file is rebuilt using \f[C]mi5(1df)\f[] and
\f[C]make(1)\f[] because it requires hard\-coding a path to the SKS
keyserver certificate authority, and neither tilde nor \f[C]$HOME\f[]
expansion works for this.
.SS Mutt
.PP
My mail is kept in individual Maildirs under \f[C]~/Mail\f[], with
\f[C]inbox\f[] being where most unfiltered mail is sent.
I use Getmail (http://pyropus.ca/software/getmail/),
maildrop (https://www.courier-mta.org/maildrop/), and
msmtp (http://msmtp.sourceforge.net/); the configurations for these are
not included here.
I sign whenever I have some indication that the recipient might be using
a PGP implementation, and I encrypt whenever I have a public key
available for them.
The GnuPG and S/MIME interfacing is done with
GPGme (https://www.gnupg.org/related_software/gpgme/), rather than
defining commands for each crypto operation.
I wrote an article about this
setup (https://sanctum.geek.nz/arabesque/linux-crypto-email/) if it
sounds appealing.
.PP
You'll need Abook (http://abook.sourceforge.net/) installed if you want
to use the \f[C]query_command\f[] I have defined, and
msmtp (http://msmtp.sourceforge.net/) for the \f[C]sendmail\f[] command.
.SS rxvt\-unicode
.PP
I've butchered the URxvt Perl extensions
\f[C]selection\-to\-clipboard\f[] and \f[C]selection\f[] into a single
\f[C]select\f[] extension in \f[C]~/.urxvt/ext\f[], which is the only
extension I define in \f[C]~/.Xresources\f[].
.PP
The included \f[C]\&.Xresources\f[] file assumes that \f[C]urxvt\f[] can
use 256 colors and Perl extensions.
If you're missing functionality, try changing \f[C]perl\-ext\-common\f[]
to \f[C]default\f[].
.PP
My choice of font is Ubuntu Mono (http://font.ubuntu.com/), but the file
should allow falling back to the more common Deja Vu Sans
Mono (https://dejavu-fonts.github.io/).
I've found Terminus (http://terminus-font.sourceforge.net/) works well
too, but bitmap fonts are not really my cup of tea.
The Lohit Kannada font bit is purely to make ಠ_ಠ work correctly.
( ͡° ͜ʖ ͡°) seems to work out of the box.
.SS tmux
.PP
These are just generally vi\-friendly settings, not much out of the
ordinary.
Note that the configuration presently uses a hard\-coded 256\-color
color scheme, and uses non\-login shells, with an attempt to control the
environment to stop shells thinking they have access to an X display.
.PP
The shell scripts in \f[C]bin\f[] include \f[C]tm(1df)\f[], a shortcut
to make \f[C]attach\f[] into the default command if no arguments are
given and sessions do already exist.
My \f[C]~/.inputrc\f[] file binds Alt+M to run that, and Tmux in turn
binds the same key combination to detach.
.SS Vim
.PP
The majority of the Vim configuration is just setting options, with a
fair few mappings and remappings, both global and buffer\-local.
I try not to deviate too much from the Vim defaults behavior in terms of
interactive behavior and keybindings.
It's extensively commented, mostly because I was reading through it one
day and realized I'd forgotten what half of it did.
System\-specific configuration files go in \f[C]~/.vim/config\f[].
.SS Filetypes
.PP
I define my own \f[C]filetype.vim\f[] and \f[C]scripts.vim\f[], so that
filetype detection works in a way I like, and loads quickly.
They are very unlikely to suit you as they are, but you might be able to
extend them with your favourite filetypes.
If you delete both of them from \f[C]~/.vim\f[], you'll get the stock
filetype detection back.
.SS Plugins
.PP
If the logic for doing something involves more than a few lines or any
structures like functions, I like to implement it as a plugin in
\f[C]~/.vim/plugin\f[] and/or \f[C]~/.vim/autoload\f[], with
documentation for each in \f[C]~/.vim/doc\f[].
.PP
They eventually get either discarded or spun off into their own
repositories, added to this repository as submodules under
\f[C]vim/bundle\f[] instead, and uploaded to
vim.org (https://www.vim.org/account/profile.php?user_id=73687).
.PP
I still use two third\-party plugins: Tim Pope's
repeat.vim (https://www.vim.org/scripts/script.php?script_id=2136) and
surround.vim (https://www.vim.org/scripts/script.php?script_id=1697).
In my opinion, these plugins are so fundamental and useful that they
should have been implemented in or bundled with Vim itself many years
ago.
.SS Filetype plugins
.PP
I also define a few rules specific to file types I often edit in
\f[C]~/.vim/after/ftplugin\f[], including some buffer\-local mapping
targets for checking, linting, and tidying, and a few more in
\f[C]~/.vim/after/indent\f[].
There are also a few tweaks to core syntax files in
\f[C]~/.vim/after/syntax\f[], especially for shell script
(\f[C]sh.vim\f[]).
Some of these filetype plugins are also due to be separately distributed
and installed via submodules instead.
.SS Compilers
.PP
I define a few of my own \f[C]:compiler\f[] scripts for
\f[C]~/.vim/compiler\f[], for use for checking and linting of
appropriate filetypes.
Because checking (does it work?) and linting (is it well\-written?) are
separate processes for me, I bind them separately with local leader
maps; for example, \f[C]_c\f[] runs a \f[C]perl\ \-c\f[] syntax check of
Perl scripts, and \f[C]_l\f[] runs a Perl::Critic check.
.SS Neovim
.PP
I test my configuration every now and then with the Neovim
fork (https://neovim.io/).
There's an \f[C]install\-neovim\f[] target to run \f[C]install\-vim\f[]
with the appropriate paths changed.
.PP
Its godless
arrogance (https://twitter.com/tpope/status/437019518444240896)
notwithstanding, I do rather like Neovim overall, but I'm not presently
using it as my daily driver, and so it might balk at recent addenda to
my configuration.
.SS Scripts
.PP
Where practical, I make short scripts into POSIX (but not Bourne)
\f[C]sh(1)\f[], \f[C]awk(1)\f[], or \f[C]sed(1)\f[] scripts in
\f[C]~/.local/bin\f[].
I try to use shell functions only when I actually need to, which tends
to be when I need to tinker with the namespace of the user's current
shell.

.SS Manuals
.PP
The \f[C]install\-bin\f[] and \f[C]install\-games\f[] targets install
manuals for each script they install.
If you want to use the manuals, you may need to add
\f[C]~/.local/share/man\f[] to your \f[C]~/.manpath\f[] or
\f[C]/etc/manpath\f[] configuration, depending on your system.
.SS Testing
.PP
You can check that both sets of shell scripts are syntactically correct
with \f[C]make\ check\-bash\f[], \f[C]make\ check\-sh\f[], or
\f[C]make\ check\f[] for everything including the scripts in
\f[C]bin\f[] and \f[C]games\f[].
There's no proper test suite for the actual functionality (yet).

There are also optional \f[C]lint\f[] targets, if you have the
