Arch Linux Configuration

My arch linux configuration files for openbox, bash, git, tmux & vim.

rc.xml

~/.config/openbox/rc.xml is the configuration file used by the openbox window manager (or openbox-multihead-git in my case). Features in my rc.xml include:

• basic modifications that can be done in obconf
• keybind constructs
  • F12 for [urxvtq] 1
  • super-l to lock the computer
  • super-c to run an ssh session to the server 'central' (using urxvtc)
  • super-x to do the above with an X forwarding session
  • super-v to open a vim instance (in urxvtc)
  • super-e to run thunar (gui file browser)
  • PrtScr & ctrl-PrtScr for printscreen functionality
  • fn-key volume controls (& show level using notify-osd)
  • super-< & super-> to snap windows left and right
  • super-^ maxmize (shade if maximized)
  • super-v restore down (shade if already unmaximized)
  • super-+ add a workspace at the end of the current list
  • super-bkspc remove the current workspace (windows shuffle to previous workspace)
  • super-d show desktop
• mousebind modifications
  • removed unfocus from scroll on titlebar (now only shade/unshade)
• added application properties for [urxvtq] 1

.bashrc

![term screenshot] (http://raw.github.com/kevna/my-configs/master/terminal-screenshot.png) The prompt can be read as follows:
user(virtualTerminal:backgroundProcessCount)@hostname[battery]:directory ∓branch(changes)
|-errorCode-historyNumber--

The battery information is gathered using the external script .batstring. The ∓ flag (git logo) appears when the present working directory is a git repo, when it appears it is followed by the name of the currently active branch and (in the brackets) the number of un-commited changes. and the error code is replaced with a green tick if 0 (clean exit).

A wealth of information on configuring and colouring bash prompts can be found on the [ArchWiki] 2

.batstring

~/.batstring is a simple script only used by my bash prompt. It uses acpi to capture the battery state as a percentage remaining charge. For quick reading the battery value is colour coded:

• bold white - full
• plain cyan - discharging
• plain red - low (< 1/4)
• flash red - danger (< 10%)
• bold cyan - charging (bold white is also used to catch other battery states that may occur)

.vim & .vimrc

![vim screenshot] (http://raw.github.com/kevna/my-configs/master/vim-screenshot.png) In order to maintain clarity in my .vimrc file I have outsourced some of my vim configuration to files at .vim/plugin/config-* as .vim/plugin is also sourced upon vim startup.

vim plugins

The plugins written by other people that I use are as follows:

• [NERDTree] (http://www.vim.org/scripts/script.php?script_id=1658) ([github] (https://github.com/scrooloose/nerdtree))
• [taglist] (http://www.vim.org/scripts/script.php?script_id=273) ([github] (https://github.com/vim-scripts/taglist.vim))
• [AutoClose] (http://www.vim.org/scripts/script.php?script_id=2009)
• [fugitive] (http://www.vim.org/scripts/script.php?script_id=2975) ([github] (https://github.com/tpope/vim-fugitive))
• [airline] (http://www.vim.org/scripts/script.php?script_id=4661) ([github] (https://github.com/bling/vim-airline))
• syntastic
• YouCompleteMe

.vim/plugin/config-functions.vim

Currently this file contains three functions:

• WordCount allows me to see a count of words in the current file (used in my status line)
• NERDTreeQuit is a hack to auto-close the NERDTree plugin if it is the last window to remain open
• InsertTabWrapper is a wrapper function for the tab command, if there is text immediately to the left it attempts to complete it, else it inserts a tab character

.vim/plugin/config-keymaps.vim

This file holds all the keymaps I use in my vim configuration:

• keymaps
  • leader is set to ','
  • n toggles NERDTree
  • t toggles TagList
  • p toggles paste
• insert mode
  • jj switches to command mode (w)rites the file and returns to insert mode
  • Tab calls the InsertTabWrapper function for completion (can be bypassed by using Shift-Tab if you wish to insert a Tab after text)
    • this feature now depreciated with introduction of YouCompleteMe plugin.
• 'normal' mode
  • ss toggles spell-checking on or off (if version > 7)
  • ; mapped to : (because this is a normal NOT command mode keymap it only affects the first ; pressed)
  • unmapped cursor-keys (forcing use of hjkl for navigation)
• visual mode
  • ; mapped to : (as above)
• command mode
  • w!! writes the file using the 'write as sudo' hack
  • tt toggles Tlist on or off
    • this feature now depreciated (moved to mapping)

.vim/colors/candycode.vim

In majority this is the standard [candycode] 4 color scheme which is designed for use with gvim. In order to use the scheme with vim in my terminal sessions with transparency I had to remove the background color setting that is otherwise overlaid on the background. This is done by setting:

hi normal ctermbg=NONE
