=====
|
|
|
|
Self-contained, pretty and versatile `.tmux.conf` configuration file.
|
|
|
|
|
|
|
|
Installation
|
|
------------
|
|
|
|
Requirements:
|
|
|
|
- tmux **`>= 2.1`** running inside Linux, Mac, OpenBSD, Cygwin or WSL (Bash on
|
|
Ubuntu on Windows)
|
|
- outside of tmux, `$TERM` must be set to `xterm-256color`
|
|
|
|
To install, run the following from your terminal: (you may want to backup your
|
|
existing `~/.tmux.conf` first)
|
|
|
|
```
|
|
$ cd
|
|
$ git clone https://github.com/tnory56/.tmux.git
|
|
$ git clone https://github.com/tmux-plugins/tpm ~/.tmux/plugins/tpm
|
|
$ ln -s -f .tmux/.tmux.conf
|
|
$ cp .tmux/.tmux.conf.local .
|
|
```
|
|
|
|
Then proceed to [customize] your `~/.tmux.conf.local` copy.
|
|
|
|
[customize]: #enabling-the-powerline-look
|
|
|
|
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).
|
|
|

Troubleshooting
|
|
---------------
|
|
|
|
- **I'm running tmux `HEAD` and things don't work properly. What should I do?**
|
|
|
|
Please open an issue describing what doesn't work with upcoming tmux. I'll do
|
|
my best to address it.
|
|
|
|
- **Status line is broken and/or gets duplicated at the bottom of the screen.
|
|
What gives?**
|
|
|
|
This particularly happens on Linux when the distribution provides a version
|
|
of glib that received Unicode 9.0 upgrades (glib `>= 2.50.1`) while providing
|
|
a version of glibc that didn't (glibc `< 2.26`). You may also configure
|
|
`LC_CTYPE` to use an `UTF-8` locale. Typically VTE based terminal emulators
|
|
rely on glib's `g_unichar_iswide()` function while tmux relies on glibc's
|
|
`wcwidth()` function. When these two functions disagree, display gets messed
|
|
up.
|
|
|
|
This can also happen on macOS when using iTerm2 and "Use Unicode version 9
|
|
character widths" is enabled in `Preferences... > Profiles > Text`
|
|
|
|
For that reason, the default `~/.tmux.conf.local` file stopped using Unicode
|
|
characters for which width changed in between Unicode 8.0 and 9.0 standards,
|
|
as well as Emojis.
|
|
|
|
- **I installed Powerline and/or (patched) fonts but can't see Powerline
|
|
symbols.**
|
|
|
|
First, you don't need to install Powerline. You only need fonts patched with
|
|
Powerline symbols or the standalone `PowerlineSymbols.otf` font. Then make
|
|
sure your `~/.tmux.conf.local` copy uses the right code points for
|
|
`tmux_conf_theme_left_separator_XXX` values.
|
|
|
|
- **I'm using Bash On Windows (WSL), colors and Powerline look are broken.**
|
|
|
|
There is currently a [bug][1681] in the new console powering Bash On Windows
|
|
preventing text attributes (bold, underscore, ...) to combine properly with
|
|
colors. The workaround is to search your `~/.tmux.conf.local` copy and
|
|
replace attributes with `'none'`.
|
|
|
|
Also, until Window's console replaces its GDI based render with a DirectWrite
|
|
one, Powerline symbols will be broken.
|
|
|
|
The alternative is to use the [Mintty terminal for WSL][wsltty].

|
|
|
|
The "maximize any pane to a new window with `<prefix> +`" feature is different
|
|
from builtin `resize-pane -Z` as it allows you to further split a maximized
|
|
pane. It's also more flexible by allowing you to 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 `<prefix> +`
|
|
either from the source window or the maximized window.
|
|
|
|
|
|
|
|
Mouse mode allows you to set the active window, set the active pane, resize
|
|
panes and automatically switches to copy-mode to select text.

|
Bindings
|
|
--------
|
|
|
|
tmux may be controlled from an attached client by using a key combination of a
|
|
prefix key, followed by a command key. This configuration uses `C-a` as a
|
|
secondary prefix while keeping `C-b` as the default prefix. In the following
|
|
list of key bindings:
|
|
- `<prefix>` means you have to either hit <kbd>Ctrl</kbd> + <kbd>a</kbd> or <kbd>Ctrl</kbd> + <kbd>b</kbd>
|
|
- `<prefix> c` means you have to hit <kbd>Ctrl</kbd> + <kbd>a</kbd> or <kbd>Ctrl</kbd> + <kbd>b</kbd> followed by <kbd>c</kbd>
|
|
- `<prefix> C-c` means you have to hit <kbd>Ctrl</kbd> + <kbd>a</kbd> or <kbd>Ctrl</kbd> + <kbd>b</kbd> followed by <kbd>Ctrl</kbd> + <kbd>c</kbd>
|
|
|
|
This configuration uses the following bindings:
|
|
|
|
- `<prefix> e` opens `~/.tmux.conf.local` with the editor defined by the
|
|
`$EDITOR` environment variable (defaults to `vim` when empty)
|
|
- `<prefix> r` reloads the configuration
|
|
- `C-l` clears both the screen and the tmux history
|
|
|
|
- `<prefix> C-c` creates a new session
|
|
- `<prefix> C-f` lets you switch to another session by name
|
|
|
|
- `<prefix> C-h` and `<prefix> C-l` let you navigate windows (default
|
|
`<prefix> n` and `<prefix> p` are unbound)
|
|
- `<prefix> Tab` brings you to the last active window
|
|
|
|
- `<prefix> -` splits the current pane vertically
|
|
- `<prefix> _` splits the current pane horizontally
|
|
- `<prefix> h`, `<prefix> j`, `<prefix> k` and `<prefix> l` let you navigate
|
|
panes ala Vim
|
|
- `<prefix> H`, `<prefix> J`, `<prefix> K`, `<prefix> L` let you resize panes
|
|
- `<prefix> <` and `<prefix> >` let you swap panes
|
|
- `<prefix> +` maximizes the current pane to a new window
|
|
|
|
- `<prefix> m` toggles mouse mode on or off
|
|
|
|
- `<prefix> U` launches Urlview (if available)
|
|
- `<prefix> F` launches Facebook PathPicker (if available)
|
|
|
|
- `<prefix> Enter` enters copy-mode
|
|
- `<prefix> b` lists the paste-buffers
|
|
- `<prefix> p` pastes from the top paste-buffer
|
|
- `<prefix> P` lets you choose the paste-buffer to paste from
|
|
|
|
Additionally, `copy-mode-vi` matches [my own Vim configuration][]
|
|
|
|
[my own Vim configuration]: https://github.com/gpakosz/.vim.git
|
|
|
|
Bindings for `copy-mode-vi`:
|
|
|
|
- `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
|
|
|
|
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.
|
|
|
|
Please refer to the default `~/.tmux.conf.local` file to know more about
|
|
variables you can adjust to alter different behaviors. Pressing `<prefix> e`
|
|
will open `~/.tmux.conf.local` with the editor defined by the `$EDITOR`
|
|
environment variable (defaults to `vim` when empty).
|
|
|
|
### Enabling the Powerline look
|
|
|
|
Powerline originated as a status-line plugin for Vim. Its popular eye-catching
|
|
look is based on the use of special symbols: <img width="80" alt="Powerline Symbols" style="vertical-align: middle;" src="https://cloud.githubusercontent.com/assets/553208/10687156/1b76dda6-796b-11e5-83a1-1634337c4571.png" />
|
|
|
|
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
|
|
[2.030R-ro/1.050R-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][terminal support]
|
|
- [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]
|
|

|
|
|
|
Please see the [Powerline manual] for further details.
|
|
|
|
Then edit the `~/.tmux.conf.local` file (`<prefix> e`) and adjust the following
|
|
variables:
|
|
|
|
```
|
|
tmux_conf_theme_left_separator_main=''
|
|
tmux_conf_theme_left_separator_sub=''
|
|
tmux_conf_theme_right_separator_main=''
|
|
tmux_conf_theme_right_separator_sub=''
|
|
```
|
|
### Configuring the status line
|
|
|
|
Contrary to the first iterations of this configuration, by now you have total
|
|
control on the content and order of `status-left` and `status-right`.
|
|
|
|
Edit the `~/.tmux.conf.local` file (`<prefix> e`) and adjust the
|
|
`tmux_conf_theme_status_left` and `tmux_conf_theme_status_right` variables to
|
|
your own preferences.
|
|
|
|
This configuration supports the following builtin variables:
|
|
|
|
- `#{battery_bar}`: horizontal battery charge bar
|
|
- `#{battery_percentage}`: battery percentage
|
|
- `#{battery_status}`: is battery charging or discharging?
|
|
- `#{battery_vbar}`: vertical battery charge bar
|
|
- `#{circled_session_name}`: circled session number, up to 20
|
|
- `#{hostname}`: SSH aware hostname information
|
|
- `#{hostname_ssh}`: SSH aware hostname information, blank when no SSH
|
|
connection detected
|
|
- `#{loadavg}`: load average
|
|
- `#{pairing}`: is session attached to more than one client?
|
|
- `#{prefix}`: is prefix being depressed?
|
|
- `#{root}`: is current user root?
|
|
- `#{synchronized}`: are the panes synchronized?
|
|
- `#{uptime_d}`: uptime days
|
|
- `#{uptime_h}`: uptime hours
|
|
- `#{uptime_m}`: uptime minutes
|
|
- `#{uptime_s}`: uptime seconds
|
|
- `#{username}`: SSH aware username information
|
|
- `#{username_ssh}`: SSH aware username information, blank when no SSH
|
|
connection detected
|
|
|
|
### Accessing the macOS clipboard from within tmux sessions
|
|
|
|
[Chris Johnsen created the `reattach-to-user-namespace`
|
|
utility][reattach-to-user-namespace] 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.
|
|

|
|
|
### Using the configuration under Cygwin within Mintty
|
|
|
|
**I don't recommend running this configuration with Cygwin anymore. Forking
|
|
under Cygwin is extremely slow and this configuration issues a lot of
|
|
`run-shell` commands under the hood. As such, you will experience high CPU
|
|
usage. As an alternative consider using [Mintty terminal for WSL][wsltty].**
|
|
|
|
|
|
|
|
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 of double width symbols, like the battery discharging symbol indicator
|
|
(U+1F50B) is buggy
|
|
|
|
To get Unicode symbols 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.
