.tmux ===== Self-contained, pretty and versatile `.tmux.conf` configuration file. ![Screenshot](https://cloud.githubusercontent.com/assets/553208/9889393/85e50e4e-5bfa-11e5-99d8-76572350803a.gif) The `master` branch targets tmux `HEAD`. You may want to use the `1.9`, `2.0` or `2.1` branch. Features -------- - `C-a` acts as secondary prefix, while keeping default `C-b` prefix - visual theme inspired by [Powerline][] - [maximize any pane to a new window with ` +`](http://pempek.net/articles/2013/04/14/maximizing-tmux-pane-new-window/) - mouse mode toggle with ` m` - automatic usage of `reattach-to-user-namespace` if available - laptop battery status - optional highlight of focused pane (tmux `2.1`+) - configurable new windows and panes behavior (optionally retain current path) - [Facebook PathPicker][] integration if available - [Urlview][] integration if available [Powerline]: https://github.com/Lokaltog/powerline [Facebook PathPicker]: https://facebook.github.io/PathPicker/ [Urlview]: https://packages.debian.org/stable/misc/urlview This configuration uses the following bindings: - ` C-c` creates a new session - ` e` opens `~/.tmux.conf.local` with the editor defined by the `$EDITOR` environment variable (defaults to `vim` when empty) - ` r` reloads the configuration - ` C-f` lets you switch to another session by name - ` C-h` and ` C-l` let you navigate windows (default ` n` and ` p` are unbound) - ` Tab` brings you to the last active window - ` h`, ` j`, ` k` and ` l` let you navigate panes ala Vim - ` H`, ` J`, ` K`, ` L` let you resize panes - ` <` and ` >` let you swap panes - ` +` maximizes the current pane to a new window - ` m` toggles mouse mode on or off - ` U` launches Urlview (if available) - ` F` launches Facebook PathPicker (if available) - ` Enter` enters copy-mode - ` b` lists the paste-buffers - ` p` pastes from the top paste-buffer - ` P` lets you choose the paste-buffer to paste from - `C-l` clears both the screen and the history Additionally, `vi-choice`, `vi-edit` and `vi-copy` named tables are adjusted to closely match [my own Vim configuration][] [my own Vim configuration]: https://github.com/gpakosz/.vim.git Bindings for the `vi-choice` mode-table: - `h` collapses the current tree node - `l` expands the current tree node - `H` collapses all the tree nodes - `L` expands all the tree nodes - `K` jumps to the start of list (tmux 2.0+) - `L` jumps to the end of list (tmux 2.0+) - `Escape` cancels the current operation Bindings for the `vi-edit` mode-table: - `H` jumps to the start of line - `L` jumps to the end of line - `q` cancels the current operation - `Escape` cancels the current operation Bindings for the `vi-copy` mode-table: - `v` begins selection / visual mode - `C-v` toggles between blockwise visual mode and visual mode - `H` jumps to the start of line - `L` jumps to the end of line - `y` copies the selection to the top paste-buffer - `Escape` cancels the current operation The "maximize any pane to a new window with ` +`" feature is different from stock `resize-pane -Z` as it allows you to further split a maximized pane. Also, you can maximize a pane to a new window, then change window, then go back and the pane is still in maximized state in its own window. You can then minimize a pane by using ` +` either from the source window or the maximized window. ![Maximize pane](https://cloud.githubusercontent.com/assets/553208/9890858/ee3c0ca6-5c02-11e5-890e-05d825a46c92.gif) Mouse mode allows you to set the active window, set the active pane, resize panes and select switch to copy-mode to select text. ![Mouse mode](https://cloud.githubusercontent.com/assets/553208/9890797/8dffe542-5c02-11e5-9c06-a25b452e6fcc.gif) Installation ------------ $ cd $ rm -rf .tmux $ git clone https://github.com/gpakosz/.tmux.git $ ln -s .tmux/.tmux.conf $ cp .tmux/.tmux.conf.local . If you're a Vim user, setting the `$EDITOR` environment variable to `vim` will enable and further customize the vi-style key bindings (see tmux manual). Configuration ------------- While this configuration tries to bring sane default settings, you may want to customize it further to your needs. Instead of altering the `~/.tmux.conf` file and diverging from upstream, the proper way is to edit the `~/.tmux.conf.local` file: echo "set -g history-limit 10000" >> ~/.tmux.conf.local You will also notice the default `.tmux.conf.local` file contains variables you can change to alter different behaviors. Pressing ` e` will open `~/.tmux.conf.local` with the editor defined by the `$EDITOR` environment variable (defaults to `vim` when empty). ### Enabling the Powerline like visual theme Powerline originated as a status-line plugin for Vim. Its popular eye-catching look is based on the use of special symbols: Powerline Symbols To make use of these symbols, there are several options: - use a font that already bundles those: this is e.g. the case of the [2.010R-ro/1.030R-it version][source code pro] of the Source Code Pro] font - use a [pre-patched font][powerline patched fonts] - use your preferred font along with the [Powerline font][powerline font] (that only contains the Powerline symbols): this highly depends on your operating system and your terminal emulator - [patch your preferred font][powerline font patcher] by adding the missing Powerline symbols: this is the most difficult way and is no more documented in the Powerline manual [source code pro]: https://github.com/adobe-fonts/source-code-pro/releases/tag/2.010R-ro%2F1.030R-it [powerline patched fonts]: https://github.com/powerline/fonts [powerline font]: https://github.com/powerline/powerline/raw/develop/font/PowerlineSymbols.otf [powerline font patcher]: https://github.com/powerline/fontpatcher Please see the [powerline manual] for further details. Then edit the `~/.tmux.conf.local` file (` e`) and adjust the `tmux_conf_theme` variable: tmux_conf_theme=powerline The possible values for `tmux_conf_theme` are `default` and `powerline`.

The battery indicator can either be a charging bar or a percentage which is controlled by the `tmux_conf_battery_style` variable: tmux_conf_battery_style=bar The possible values for `tmux_conf_battery_style` are `bar` (default) or `percentage`. You can also customize the symbol used in the battery bar as well as their number by adjusting the `tmux_conf_battery_symbol` and `tmux_conf_battery_symbol_count` variables. tmux_conf_battery_symbol=heart tmux_conf_battery_symbol_count=5 The possible values for `tmux_conf_battery_symbol` are `block` (default) or `heart`. The default number of symbol displayed is `10`. To customize the battery bar colors, adjust the `tmux_conf_battery_palette` variable. You can either specify a `'colour_full_fg,colour_empty_fg,colour_bg'` colour triplet or one of the `heat` or `gradient` aliases. See tmux manual for colours definition: > The colour is one of: black, red, green, yellow, blue, magenta, cyan, white, > aixterm bright variants (if supported: brightred, brightgreen, and so on), > colour0 to colour255 from the 256-colour set, default, or a hexadecimal RGB > string such as `#ffffff`, which chooses the closest match from the default > 256-colour set. To use the heat palette for the battery indicator, use: tmux_conf_battery_palette=heat To use the gradient palette for the battery indicator, use: #tmux_conf_battery_palette=heat To disable the battery charging (⚡ U+26A1) / discharging (🔋 U+1F50B) status, adjust the `tmux_conf_battery_status` variable: tmux_conf_battery_status=disabled The possible values for `tmux_conf_battery_status` are `enabled` (default) or `disabled`. ### Configuring the date and time To disable the display of date and time, edit the `~/.tmux.conf.local` file (` e`) and adjust the `tmux_conf_theme_date` and `tmux_conf_theme_time` variables: tmux_conf_theme_time=disabled tmux_conf_theme_date=disabled The possible values for `tmux_conf_theme_date` and `tmux_conf_theme_time` are `enabled` (default) or `disabled`. ### Configuring the username and hostname To disable the display of username and hostname, edit the `~/.tmux.conf.local` file (` e`) and adjust the `tmux_conf_theme_username` and `tmux_conf_theme_hostname` variables: tmux_conf_theme_username=disabled tmux_conf_theme_hostname=disabled The possible values for `tmux_conf_theme_username` and `tmux_conf_theme_hostname` are `enabled` (default) or `disabled`, or `ssh`. When you set `tmux_conf_theme_username` or `tmux_conf_theme_hostname` to `ssh`, information is displayed only if you're inside an SSH session. ### Configuring highlighting of the focused pane To highlight the focused pane, edit the `~/.tmux.conf.local` file (` e`) and adjust the `tmux_conf_theme_highlight_focused_pane` variable: tmux_conf_theme_highlight_focused_pane=enabled The possible values for `tmux_conf_theme_highlight_focused_pane` variable are `disabled` (default) or `enabled`. This feature is only available from tmux `2.1`. ### Configuring new windows and new panes creation To configure whether creating new windows and new panes retains the current path, edit the `~/.tmux.conf.local` (` e`) and adjust the `tmux_conf_new_windows_retain_current_path` and `tmux_conf_new_panes_retain_current_path` variables: tmux_conf_new_windows_retain_current_path=false tmux_conf_new_panes_retain_current_path=true The possible values for `tmux_conf_new_windows_retain_current_path` and `tmux_conf_new_panes_retain_current_path` are `true` or `false`. ### Accessing the Mac OSX clipboard from within tmux sessions [Chris Johnsen created the `reattach-to-user-namespace` utility](https://github.com/ChrisJohnsen/tmux-MacOSX-pasteboard) that makes `pbcopy` and `pbpaste` work again within tmux. To install `reattach-to-user-namespace`, use either [MacPorts][] or [Homebrew][]: $ port install tmux-pasteboard or $ brew install reattach-to-user-namespace Once installed, `reattach-to-usernamespace` will be automatically detected. [MacPorts]: http://www.macports.org/ [Homebrew]: http://brew.sh/ ### Using the configuration under Cygwin within Mintty ![image](https://cloud.githubusercontent.com/assets/553208/10802824/32539f02-7dbf-11e5-9377-2008192a7396.png) It is possible to use this configuration under Cygwin within Mintty, however support for Unicode symbols and emojis lacks behind Mac and Linux. Particularly, Mintty's text rendering is implemented with GDI which has limitations: - color emojis are only available through DirectWrite starting with Windows 8.1 - display double width symbols, like the battery discharging symbol indicator (U+1F50B) is buggy As a consequence, under Cygwin, the battery charging (⚡ U+26A1) status indicator is rendered as a monochrome lightning bolt instead of a colorful emoji while the discharging (🔋 U+1F50B) one is simply disabled. Also, to get the battery charging status indicator displayed properly, you have to use [font linking]. Open `regedit.exe` then navigate to the registry key at `HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontLink\SystemLink` and add a new entry for you preferred font to link it with the Segoe UI Symbol font. ![image](https://cloud.githubusercontent.com/assets/553208/10802432/26341fbe-7dbd-11e5-9be9-585348fe3c2c.png) [font linking]: https://msdn.microsoft.com/en-us/goglobal/bb688134.aspx
