tma: The tmux Automator

tma is defined not so much by what I want in a tmux automation solution, but more by what I don't. To wit:

• I don't want a full interpreted programming language. Instead, give me a single binary I can scp to remote servers or compile for just about anything.
• I don't want a full programming language in my automation specifications. I should be able to bang something out from memory to open a few windows and panes, and set them up like I want. TOML should work nicely.
• I don't want a bunch of project-specific settings in my automation, particularly when I'll likely copy the same setup to every Node/Rust/Elixir project I start. Why should my tmux automation care about a session name when it can probably infer it from the current directory? Likewise, why do I need to specify a root directory? I should be able to give someone else my setup and have it run unmodified for them.
• I don't want my automation solution to do more than automate tmux. Don't manage a directory of configurations, spawn my editor, or do things other than rock at automating tmux.

So, here's tma.

Building

You'll need a Rust toolchain installed. With that in place, simply check out this repository and run:

$ cargo install

You'll end up with $HOME/.cargo/bin/tma.

Configuring

tma looks for its configuration in .tma.toml in the current directory. Use the -c command line switch to specify a different filename.

Here is a full commented example of all currently-supported options:

name = "myproject" # optional, tmux session name, defaults to current directory name if unset
root = "src" # optional, relative path from which all tmux commands are executed, defaults to current directory
attach = true # optional, indicates whether or not to attach to the created session, true by default

[[window]]
name = "code" # optional window named
root = "code" # optional, path at which this window is open, relative from the session root

[[window.pane]]
root = "subdir" # optional, path at which this pane is open, relative from the session and window root
command = "vim" # optional, command run in this pane
split = "horizontal" # optional, splits this window horizontally, all other values ignored
...

Example

Here is the .tma.toml file I use while developing this project:

[[window]]
name = "code"

[[window.pane]]
command = "vim"

[[window.pane]]
command = "cargo watch"

This opens a tmux session with Vim on top and cargo watch below.
