tmux.vim

This repository provides a Vim syntax highlighting file for tmux configurations. The syntax file is generated directly from the tmux source code using an Awk script. A cron job running on a host managed by the maintainer of this repository regenerates the syntax file once a day and, if the syntax file has changed, commits the change then pushes it to GitHub. As such, this repository should always have a fairly up-to-date syntax file as long as there has not been any significant refactoring by the tmux maintainers.

The syntax file was derived from Keith Smiley's tmux.vim with some changes:

• When a color is used (e.g. "colour7"), the text's foreground is changed to reflect the color that the number represents. For darker colors, the background is changed to white since the text might otherwise be invisible. This can be disabled by setting g:tmux_syntax_colors = 0 in your vimrc file.
• Distinct highlighting has been added for interpolated blocks (#[...], #(...) and #{...}).
• Multi-line strings are supported and correctly highlighted.
• The highlighting style has been modified; what is considered a boolean, identifier, etc. in this version of the syntax file differs from Keith's.

Installation

The syntax file is included with Vim as of version 8.0.0420, but users wanting a more up-to-date syntax file can use this repository directly.

Makefile

Assuming make(1) is installed and there is an existing Vim directory at $HOME/.vim, running make install should be sufficient.

Plugin Manager

This repository should work with most Vim plugin managers that support tracking Git repositories. Since the files needed by Vim at runtime are in the subdirectory "vim/", the plugin managers will typically need to be configured to load files from the correct folder:

• dein: call dein#add('ericpruitt/tmux.vim', {'rtp': 'vim/'})

• vim-plug: Plug 'ericpruitt/tmux.vim', {'rtp': 'vim/'}

• Vundle: Plugin 'ericpruitt/tmux.vim', {'rtp': 'vim/'}

Development

In addition to the Makefile, there are two other components to this repository used to generate the syntax file. The top portion of the syntax file that defines syntax-matching regular expressions is found in "./src/header.vim". It is combined with the output of "./src/dump-keywords.awk", an Awk script that accepts tmux C source files as arguments then dumps extracted command and option names. The Makefile and Awk script are POSIX-compliant.

Makefile Targets

• build: Download the tmux source code and generate or update the Vim syntax file. This is the default target used when none are explicitly given.
• install: Install the Vim files in $HOME/.vim.
• sync: Pull the latest tmux commits, update the Vim syntax file then commit the changes. If "PUSH_AFTER_SYNC" is set to "true", the commit will automatically be pushed upstream i.e. make PUSH_AFTER_SYNC=true sync. The default value of "PUSH_AFTER_SYNC" is "false".
