Arkku's .dotfiles

This repository contains my "public" shell configuration files. The ones in this repository are not in any way specific to me, and could theoretically be used by others who share similar preferences.

However, possibly the most interesting thing here is the link_files script, which is used to hard-link the files from this repository into the home directory, while allowing platform-specific files and local overrides. See link_files --help.

Features

This is an incomplete set of features, mainly as a reminder for myself when some years later I have forgotten what I set up. =)

Vim

Configuration and colour scheme (imaginatively named arkku) for Vim and Neovim. The colour scheme supports both light and dark backgrounds, and works in an EGA/VGA text-mode terminal. Even if the background is mistakenly set as light, the colour scheme is still usable, allowing me to keep light background as the default.

Some other general settings done:

• if rg is installed, use it instead of grep (also in plugins), otherwise use ag if that is installed
• if fzf is installed (via brew, apt, or in ~./fzf), load its plugin, and use the first of fd, rg or ag that is installed to power the search
• g:markdown_fenced_languages is set to contain a variety of popular languages but only if the filetype is known (e.g., swift is not currently shipped with Vim, so it would cause an error if added without the plugin installed)
• formatting of markdown lists is fixed
• the Neovim configuration tries to detect the background colour from the environment variables $BACKGROUND (dark or light) and $COLORFGBG (<fgcolor>;<bgcolor>, e.g., 7;0 is gray on black)

Many settings assume that my plugin collection is installed, and some plugin-related settings are in that collection (and not duplicated here anymore).

General Bindings

• p – in visual mode, put (paste) over the selection without yanking the replaced text
• K – show documentation for word under cursor (using coc or ale if available, otherwise the normal Vim behaviour)
• arrows (with Ctrl and Alt) escape sequences explicitly bound for various different terminals (not in Neovim)
• Alt-arrow mapped the same way as in macOS, i.e., skip words left/right, or to beginning/end of line
• Ctrl–left and Ctrl–right mapped the same way as in macOS, i.e., line beginning/end
• Ctrl–up and Ctrl–down move visually, i.e., lines on screen instead of lines in file
• Ctrl-A – go to the beginning of line
• Ctrl-E – go to the end of line (unless pop-up completion menu is open, in which case close it)
• Ctrl–B – in insert mode, insert the character below the cursor (the default mapping for Ctrl–E, but even the mnemonic makes more sense now)
• Ctrl–B – toggle paste mode, paste, and toggle paste mode again (Vim only)
• Esc – exit integrated terminal (press twice quickly to send to
• Esc Esc – in insert mode, clear highlighting of previous search
• Ctrl-_ – various bindings in different modes, not settled on a final choice yet
• Ctrl–J and Ctrl–K right after putting text in normal change the text that was put by cycling put history (depends on Yoink plugin)
• Ctrl-Q – in normal mode works as the original Tab binding (since usually I use a configuration that rebinds it), i.e., jump to newer cursor position (such as after jumping to an older position with Ctrl–O, which is also conveniently adjacent in Dvorak)
• Ctrl-Q – in insert mode inserts the previously inserted text, i.e., the original behaviour of Ctrl–A

Unimpaired-style Bindings

Some additional bindings in the style of the "unimpaired" plugin:

• [oa / ]oa – turn auto-formatting (formatoptions+=a) on/off
• [ot / ]ot – turn text formatting (formatoptions+=t) on/off
• ]w, [w – jump to next/previous warning/error (using coc, ale, or the location list, in that order)

Leader Bindings

These bindings are for the normal mode, preceded by the leader (\):

• 1 – 0 – switch to vim-buffet buffer 1–10
• f – open quickfix if there are warnings/errors
• F – close quickfix
• l – open location list
• L – close location list
• q – delete buffer
• x – wipeout buffer
• d – jump to definition of thing under cursor (if coc installed)
• i – jump to implementation of thing under cursor (if coc installed)
• r – show references to the thing under cursor (if coc installed)
• e – show errors/diagnostics (if coc installed)
• o – show code outline (if coc installed)
• c – coc code action (if installed)
• R – coc rename (if installed)
• s – run Syntastic check, and open the location list if there are errors
• S – reset Syntastic, clearing all errors
• t – toggle a split terminal console (the session remains even if toggled away from view) – Neovim only
• T – split and open a terminal with the given command
• u – open function search
• / – open fzf search for lines in open buffers (if plugin installed)
• Tab – create a new tab
• Shift + Tab – close tab

Local Leader Bindings

These bindings are for the normal mode, preceded by the local leader (Space):

• 1 – 0 – switch to tab 1–10
• q – close tab
• x – force close tab
• Tab – go to next tab
• Shift + Tab – go to previous tab
• w – open warnings/errors list (coc, or location list)
• W – close warnings/errors list
• h – open fzf fuzzy search for "recently opened files" (if plugin installed)
• / – open fzf search for lines in this buffer
• s – open search for symbols (if coc is installed)
• t – open tag search (if fzf plugin is installed)
• T – open tag search (if CtrlP plugin is installed)
• z – open fzf fuzzy search for files (powered by fd if installed)

Commands

• CD – change the current window's working directory to that of the current file
• CD! – change every window's working directory to that of the current file

Shell

I have switched my default shell on most computers from bash to zsh. Many of the features described here work specifically on zsh, but many also work on bash, especially if they were configured in the 20 years before I made the switch.

Configuration exists for .inputrc and ls colours for both GNU and BSD variants. The autocompletion suggestions for zsh are also coloured. If zsh-syntax-highlighting is installed, it is loaded. The colours somewhat match my Vim colour scheme where applicable (although there is no separate dark variant so some exceptions had to be made).

There is also my .profile_shared configuration, which is meant to be sourced from .profile and .zprofile. The settings are quite specific to me, so if anyone else uses these config files, they probably shouldn't use it. But, to do so, simply:

. "$HOME/.profile_shared"

It sets EDITOR and VISUAL to nvim, vim, or vi, whichever is installed (in that order). Flow control is disabled for the terminal, allowing Ctrl–S and Ctrl–Q to be used for keyboard shortcuts.

The profiles generally ensure that rvm is loaded if installed, and that PATH contains rvm directories in the correct order. ~/bin and /usr/local/bin are also added to the path, in that order, so that things installed in /usr/local/bin override older versions shipped with the OS, and ~/bin can be used to override both.

On machines where I set umask 027 (i.e., no default permissions for others), it is also helpful to add to sudoers or /etc/sudoers.d:

Defaults umask_override
Defaults umask=0022

Prompt

• the prompt truncates the current working directory in various ways, e.g., the home directory is replaced by ~, any long path before the root of the current git repository (if any) is truncated, if there are more than four directories remaining, only the first and last two are kept, and then the remaining is truncated from the left according to available space
• the current git repository and branch are shown on the right-hand side (zsh RPROMPT feature – it disappears if input comes too close to it), and there are little +~ characters to indicate staged/unstaged changes to the repository
• the repository name is truncated from the left according to available space, and removed entirely if it is already visible in the working directory (which is true most of the time since the repository root is used as the path root)
• the branch name on the prompt is truncated according to various rules, e.g., master often becomes m (but in a different colour to distinguish from a hypothetical m branch)
• there is a single line above the prompt, which contains the current history number ($!), and the exit status of the previous command if it failed (i.e., a non-zero $?)
• git merge/rebase/patch status is also show on this line
• the vi command-mode is shown with a (vi) indicator on the above line

Autocompletion

Autocompletion is set to be case-, hyphen-, and underscore-insensitive. If fzf is installed, autocompletion is also made fuzzy.

Title

• the window/screen/tmux title shows user@host when idle, followed by the git repository and branch (if any)
• when executing a command, the title shows the command line, but precedes it with the username if sudo has been used and the hostname if it is an ssh session
• the file URL for Terminal.app is set if not in tmux and $TERM_PROGRAM is Apple_Terminal

Directory Jumping

If fasd or z.sh is installed (in that order) and the initially empty file ~/.fasd-init-zsh (or ~/.z for z.sh) exists, then it is loaded and its aliases setup. Both include at least z, which jumps to a directory matching the partial name, e.g., z dot probably jumps to ~/.dotfiles if you have been using that directory.

If fasd and fzf are both enabled, then all interactive selections in fzf are replaced by fzf.

For fasd, the set of aliases is:

• z dir – jump from anywhere to directory matching the partial name dir
• zz dir – as z, but interactively select the directory if there are multiple matches
• zzz file – interactively select a file or directory, and jump to the directory containing it (even if it is a directory in itself)
• d dir – print the directory matching the partial name dir
• sd dir – as above, but interactively disambiguate
• f file – print the file matching the partial name file
• sf dir – as above, but interactively disambiguate
• a any – print the directory or file matching the partial name any
• any any – print the directory or file matching the partial name any
• v file – edit the file in vi
• vv file – as above, but interactively disambiguate

Key Bindings

• .inputrc has bindings for a large selection of terminals
• arrow keys with alt are bound as per macOS defaults
• Ctrl–A and Ctrl–E go to the beginning/end of the line
• Alt-arrow mapped the same way as in macOS, i.e., skip words left/right, or to beginning/end of line
• Ctrl–left and Ctrl–right mapped the same way as in macOS, i.e., line beginning/end
• Ctrl-Space – opens the current command line in an editor
• Ctrl-Q – push-line-or-edit, if you are in a multi-line command it makes all prior lines editable again, otherwise it kills the line and pastes it back on the next empty prompt (e.g., use this to get rid of an unfinished command while you look at man, then it comes back automatically on the next prompt)
• Ctrl-R in zsh Vi insert mode activates a fuzzy command history search with the current command-line's contents and replaces the command-line with the selection (mnemonic: Repeat command)
• Ctrl-S in zsh Vi insert mode toggles sudo at the beginning of the command-line (also toggles the alias please on an empty line, and between vi/$EDITOR and the alias svi )
• Ctrl-Z on an empty prompt in insert mode – if the on the first line, execute fg (i.e., bring suspended process to foreground, allowing to toggle suspend/resume with the same keystroke), otherwise make previous lines of the multi-line prompt editable again
• Ctrl-U – kills the whole line (not just backwards from the cursor, as is the default)
• Ctrl-Y – yanks (or, more accurately, puts) the previously-killed line
• Ctrl-F – in zsh Vi insert mode starts a fuzzy file finder (requires fzf and fd), with keyboard shortcuts to change the list to show everything, only directories, only the current directory, or Git repository contents (including submodules)
• Ctrl-G – in zsh Vi insert mode shows a prompt to choose from Git commits, branches, tags, or files (not including submodules), or GitHub issues or pull requests, and starts a fuzzy finder for the choice, with live preview
• S + surround – in visual selection mode surrounds the selection with the given quotes, e.g., v$S" in vi command mode selects to the end of the line and surrounds the selection with " " quotes

Aliases

• ls – ls with color options
• ll – ls -l
• la – la
• l. – list hidden files only
• md – make a directory, including the parent directories (mkdir -p) and cd to it
• fcd – cd to the directory containing the argument file
• please – re-run the entire previous command with sudo (note: this is not just putting sudo in front of the command, but rather the entire command is executed under sudo so any pipes and redirects also gain privileges)
• clc – copy the last command to system clipboard
• clct – copy the last command to tmux buffer
• plc – paste command-line from system clipboard (but do not execute it)
• plct – paste command-line from tmux buffer (but do not execute it)
• cpwd – copy the current working directory to system clipboard
• cpath – copy the current path, with symlinks expanded, to system clipboard
• gr – grep, excluding .git
• vi – nvim (if installed)
• nvis – nvim -S Session.vim (if installed and the file exists)
• svi – sudo -e
• psg – grep the output of ps
• hgrep – grep history
• agrep – grep aliases
• cdf – open fzf to fuzzily search for directories and cd to the selected one (can take arguments, e.g., cdf / will search from the root instead of from the current directory)
• cdff – as cdf, but select a file and cd to the directory containing it
• fzh – use fzf to fuzzily search command history, and paste the selection on the command-line (but do not execute it)
• fzk – use fzf to fuzzily search running processes, and pass them (and any arguments) to kill

Also adds the following reusable zsh aliases that just print the selection to stdout:

• ffz – fuzzily find a file or directory
• fff – fuzzily find a find a file
• ff. – fuzzily find a file in the current directory
• ffd – fuzzily find a directory

Each of these can take a path as an argument, e.g., ffz / will seach from the root instead of from the current directory. Remember that Tab can complete the search in zsh when pressed after the closing backtick `. But also note that Ctrl–F is bound to these same features in my zsh configuration…

Aliases for Git

• cdr – cd to the root of the repository
• cdrr – cd to the root of the outermost repository (from submodules at any depth)
• gs – git status
• glast – show the last commit
• ggl – git log with a branching graph
• gcl – git clone --recurse-submodules
• gpull – git pull
• gupdate – git pull --rebase --autostash -v
• gpush – git push
• gpusht – git push && git push --tags
• gpusha – git push --all && git push --tags
• gsubu – git submodule update --init --recursive
• gsubr – git submodule update --remote --recursive
• gls – git ls-files --exclude-standard
• glsm – git ls-files -m -o --exclude-standard (modified files)
• gbranch – git checkout -b
• gfeature – make a new branch, prefixing the name given as argument with feature/, and push the branch to upstream (default origin, but may be given as the second argument)
• gfeaturedone – push and then delete the current branch if its name starts with feature/ and check out master (or the branch given as argument)
• gtag – create a new signed tag, and push tags
• gresetmb – git reset to merge base of HEAD and the commit or branch (default master) given as argument (e.g., gresetmb develop will reset the current feature branch to the point where it diverged from the branch develop, and all changes since will show as changes to the working copy)

The following aliases have an interactive, fuzzy-searchable selection which requires fzf, and most are only for zsh. Where applicable, there is an additional binding of Ctrl–A to select all. Pressing Esc leaves the selection (e.g., for gdf which intentionally doesn't close after selection).

• gcommit – interactively select files to commit, stage, unstage, edit, diff, etc
• gdf – view the diff of modified files without leaving the selection, with a live preview of the diff (this supports multiple keyboard shortcuts, shown on the screen, to perform various actions, such as staging/unstaging files, opening them in the editor or difftool, etc.), branch names given as argument also work (e.g. gdf master)
• gdfs or gstaged – view staged files and diff, unstage, or commit them
• ge – open a file in $EDITOR
• gadd – select modified files to stage (git add)
• gunstage – select staged files to unstage (git restore --staged)
• gdiscard – select modified files to discard changes of (git restore)
• gdt – select modified files to open in git difftool
• gmt – select unmerged files to open in git mergetool
• gstash – view stashes and diff them; there are also keyboard shortcuts to apply/pop the stash (Ctrl–A), and to branch the stash (Ctrl–B)
• gcheckout or gco – check out a branch or tag
• gcheckoutb or gcobranch – check out a branch
• gcheckoutt or gcotag – check out a tag
• gcheckoutc or gcocommit – check out a commit
• grebase – select branch and rebase
• grebasei – select branch and rebase interactively
• grebasec – select commit and rebase interactively
• gmerge – select branch and merge
• gmergef – select branch and merge, no fast forward (e.g., merge a feature branch and force there to be a new commit)
• greset – select a branch and reset to its state
• glog – view individual commits and their logs
• gcherry – cherry-pick an individual commit (this can take a branch as the first argument, other arguments are passed to the git commit command)
• gfixup – select a commit to fix-up with a new commit
• grevert – select a commit to revert
• gbranchdel – select a branch to remove
• gmovetobranch newbranch – move the current state to the new branch newbranch (also stashing any changes to working copy and moving them), then interactively pick a commit and hard reset the current branch to that commit (i.e., the chosen commit is the last one to keep on the current branch), then switch to the new branch (e.g., realize that the most recent commits should have been on a new feature branch, and retroactively move them to one)
• gtagdel – select a tag to remove
• gissues – view GitHub issues interactively (requires hub)
• gissuecommit – select an issue and pre-populate "Closes #" into the message of a new commit (requires hub)
• gpullrs – view GitHub pull requests interactively (requires hub)
• gcistatus – select a commit and view its CI status (requires hub)
• fzc – select one or more commits and print their hashes (e.g., to be used as part of other commands, like: git rebase --onto `fzc`Tab)
• fzbr – select a branch and print its name (e.g., to be used as part of other commands)
• fzbrr – select a branch, including remotes, and print its name (e.g., to be used as part of other commands)
• fztag – select a tag and print its name (e.g., to be used as part of other commands)
• fzbrt – select a branch or tag and print its name (e.g., to be used as part of other commands)
• fzgf – select a file from the git repository and print its name
• fzgcf – select from changed files in the git repository and print its name
• fzgfr – select a file from the git repository, or its submodules, and print its name
• fziss – select a GitHub issue and print its number (e.g., to be used as part of other commands)
• fzpullr – select a GitHub pull request and print its number (e.g., to be used as part of other commands)

Most of the commands will take arguments, which will generally be passed on to the eventual git command (e.g., gmerge --squash will result in git merge --squash). Most of commands that select a commit can take a branch name to choose commits from a branch other than the current, e.g., gcherry master would cherry-pick from commits on master. In cases where the argument doesn't make sense otherwise, it is used as the initial search, e.g., gco origin would start the branch selection with origin already written into the search. This is handy when you know that a given search term will only give one result, then you can just do gco f/barEnterEnter (although it is identical to gcoEnterf/barEnter, the former retains the search string in shell command history).

Global Aliases

Global aliases are a zsh feature that allows alias expansions anywhere on the command-line. All of mine are uppercase and begin with a : to make accidental use unlikely. The command-line is configured to expand such aliases immediately when pressing space, e.g., cat file :H1 will expand the :H1 to | head -1 so that it may be edited or followed by more pipes.

• :L – | less
• :LE - |& less
• :G – | grep
• :FG – | grep -F
• :EG – | egrep
• :GR – |& grep
• :FGR – |& grep -F
• :H1 – | head -1
• :T1 – | tail -1
• :H – | head
• :T – | tail
• :S – | sort
• :SN – | sort -n
• :SU – | sort -u
• :N – >/dev/null
• :NUL – >/dev/null 2>&1
• :WC – | wc -l
• :VL – | viless (an included script for use of vim or nvim as less)
• :VI – | vim -R -
• :VIM – |& vim -R -
• :AG – | ag

Additional Plugins

Plugins that need extensive external utilities or configuration are not included in my plugin collection. Some that I may use include:

• coc – intellisense engine
• ale – automatic linting and syntax checking on the fly

Also note that coc has various extensions that it can install by itself, e.g.:

:CocInstall coc-tag
:CocInstall coc-emoji

Clipboard

The scripts clipcopy and clippaste copy and paste to/from the system clipboard (trying to auto-detect macOS, X11, etc.). They fall back to the tmux buffer if no known system clipboard is available.

tmux

The tmux configuration enables sensible modern defaults (e.g., mouse, focus events), status bar, window titles, on-demand pane titles and borders.

Bindings

Unless otherwise noted, the following bindings are all after the prefix (Ctrl–T in my configuration):

• r – reload configuration from disk
• | – split the window horizontally, opening in the current directory
• \ – split the window horizontally at full width
• - – split the window horizontally, opening in the current directory
• _ – split the window horizontally at full width
• h – split the window vertically at full width, opening in the current directory (yes, the h splits vertically and v horizontally in tmux terminology, to match the Vim terminology where the direction describes the new pane and not the split)
• v – split the window horizontally at full width, opening in the current directory
• V – split the window horizontally and select another pane to place in the split
• H – split the window vertically and select another pane to place in the split
• M – choose a window to move to (swap with) the current
• < – swap the pane left
• > – swap the pane right
• ! – break the current pane into a new window (tab)
• A – rename the current window
• O – toggle mouse on/off
• R – refresh the screen
• S – toggle synchronize panes (i.e., all panes get the same keyboard input)
• x – kill the current pane
• X – kill the current window
• y – in copy mode, copies to the system clipboard

tmx

The included bin/tmx script is useful for launching tmux. If creates separate "master" and "slave" sessions, which allows multiple computers on the same master session to have their individual state in their private slave session. Running it without arguments generally does the correct thing, i.e., creates a new slave session and attaches it to any existing master, or creates the master if it doesn't exit.

A master session name can be given as the argument, e.g., tmx foo uses the session foo instead of the default (0), and creates the foo master if it doesn't already exist, and attaches a new slave to it. If the master session name is given, a slave session name may be given as the second argument. This will detach and recycle any existing slave session of that name, e.g., a network connection can use the same slave session to detach any hanging old connections on reconnect.

As a special case, tmx ls simply does tmux ls and exits. Also, if the first argument is prefix, the prefix is set to the second argument, and then the two first arguments are discarded. For example, tmx prefix '^a' foo would use foo as the master session name and set the prefix to Ctrl-A.

Git

The included .gitconfig_shared is not used by default, it needs to be included by copying this to .gitconfig:

[include]
	path = .gitconfig_shared

The shared configuration enables a global ignorefile ~/.gitignore_global (which ignores some common rubbish). The following aliases are added:

• unstage – unstage staged changes
• last – show the last commit
• l – pretty-print the log with colors
• ll – pretty-print the log
• gl – log with branching graph
• dt – difftool
• mt – mergetool
• pur – pull --rebase
• pura – pull --rebase --autostash
• puf – push --force-with-lease
• put – push --tags
• subu – submodule update --init --recursive
• subr – submodule update --remote --recursive
• pushu – push -u origin HEAD

The .gitconfig_shared also contains a difftool and mergetool definitions for nvim, as well as an additional mergetool definition for nvimfugitive for nvim using the fugitive.vim plugin. The tools are not enabled in this configuration, rather copy the following to your .gitconfig:

[diff]
	tool = nvim
[merge]
	tool = nvimfugitive

ssh

The configuration .ssh/config_shared sets up some defaults. It is not used by default, i.e., it needs to be included from ~/.ssh/config with:

Include config_shared

X11

The included .XResources sets up xterm with my light background colour scheme.

Terminal.app

The files ~/Documents/Arkku.terminal and ~/Documents/Arkku Dark.terminal (on macOS only) contain settings for Terminal.app, including keyboard bindings and colour schemes (the light is almost the same as my ancient xterm theme and the dark is the same as my Neovim colour scheme). These files need to be opened and imported into Terminal settings to take effect.

Screen

A legacy configuration for screen is included, since screen is still useful as a serial port terminal.

indent

Settings are provided in .indent.pro for sensible C indentation.

lldb and gdb

Settings are provided for lldb and gdb, that both simply set Intel syntax for assembly.

radare2

Settings are provided for radare2, mainly to set Intel syntax for assembly and to enable fancy UTF-8.

XCode

Colour schemes and key bindings are included for XCode. They need to be selected from preferences to be active.
