# Tmux session wizard
One prefix key to rule them all (with [fzf](https://github.com/junegunn/fzf) & [zoxide](https://github.com/ajeetdsouza/zoxide)):
- Creating a new session from a list of recently accessed directories
- Naming a session after a directory/project
- Switching sessions
- Viewing current or creating new sessions in one popup
### Elevator Pitch
Tmux is powerful, yes, but why is creating/switching sessions (arguably its main feature) is so damn hard to do? To create a new session for a project you have to run `tmux new-session -s -c `. What if you're inside tmux? Oh, wait you have to use `-d` followed by `tmux switch-client -t `. Oh, wait again! What if you're outside tmux and you want to attach to an existing session? now you have to run `tmux attach -t ` instead. What if you can't remember whether you have a session for that project or not. Guess what? Now you have to run `tmux has-session -t `. What if your project folder contains characters not accepted by tmux as a session name? What if you want to show a list of existing sessions? You run `tmux list-sessions`. What if you want to create a session for a project you've recently navigated to? What if, what if, what if.... HOW IS THAT BETTER THAN HAVING 20 TERMINAL WINDOWS OPEN?
What if you could use 1 prefix key to do all of this? Read on!
### Features
`prefix + T` (customisable) - displays a pop-up with [fzf](https://github.com/junegunn/fzf) which displays the existing sessions followed by recently accessed directories (using [zoxide](https://github.com/ajeetdsouza/zoxide)). Choose the session or the directory and voila! You're in that session. If the session doesn't exist, it will be created.
### Required
You must have [fzf](https://github.com/junegunn/fzf), [zoxide](https://github.com/ajeetdsouza/zoxide) installed and available in your path.
### Installation with [Tmux Plugin Manager](https://github.com/tmux-plugins/tpm) (recommended)
Add plugin to the list of TPM plugins in `.tmux.conf`:
```tmux
set -g @plugin '27medkamal/tmux-session-wizard'
```
Hit `prefix + I` to fetch the plugin and source it. That's it!
### Manual Installation
Clone the repo:
git clone https://github.com/27medkamal/tmux-session-wizard ~/clone/path
Add this line to the bottom of `.tmux.conf`:
```tmux
run-shell ~/clone/path/tmux-session-wizard.tmux
```
Reload TMUX environment with `$ tmux source-file ~/.tmux.conf`, and that's it.
### Customisation
You can customise the prefix key by adding this line to your `.tmux.conf`:
```tmux
set -g @session-wizard 'T'
set -g @session-wizard 'T K' # for multiple key bindings
```
You can also customise the height and width of the tmux popup by adding the follwing lines to your `.tmux.conf`:
```tmux
set -g @session-wizard-height 40
set -g @session-wizard-width 80
```
To customise the way session names are created, use `@session-wizard-mode` option. Allowed values are:
- `directory` (default)
- `full-path`
- `short-path`
```tmux
set -g @session-wizard-mode "full-path"
```
By default, `tmux-session-wizard` gives you a list of open sessions (hence the name). An alternative is that it gives you a list of _windows_ to choose from. This can be turned on using the setting `@session-wizard-windows`. Add this line to your `.tmux.conf` to enable this behaviour:
```tmux
set -g @session-wizard-windows on # default is off
```
### (Optional) Using the script outside of tmux
**Note:** you'll need to check the path of your tpm plugins. It may be `~/.tmux/plugins` or `~/.config/tmux/plugins` depending on where your `tmux.conf` is located.
bash
Add the following line to `~/.bashrc`
```sh
# ~/.tmux/plugins
export PATH=$HOME/.tmux/plugins/tmux-session-wizard/bin:$PATH
# ~/.config/tmux/plugins
export PATH=$HOME/.config/tmux/plugins/tmux-session-wizard/bin:$PATH
```
zsh
Add the following line to `~/.zprofile`
```sh
# ~/.tmux/plugins
export PATH=$HOME/.tmux/plugins/tmux-session-wizard/bin:$PATH
# ~/.config/tmux/plugins
export PATH=$HOME/.config/tmux/plugins/tmux-session-wizard/bin:$PATH
```
fish
Add the following line to `~/.config/fish/config.fish`
```fish
# ~/.tmux/plugins
fish_add_path $HOME/.tmux/plugins/tmux-session-wizard/bin
# ~/.config/tmux/plugins
fish_add_path $HOME/.config/tmux/plugins/tmux-session-wizard/bin
```
You can then run `t` from anywhere to use the script.
You can also run `t` with a relative or absolute path to a directory (similar to [zoxide](https://github.com/ajeetdsouza/zoxide)) to create a session for that directory. For example, `t ~/projects/my-project` will create a session named `my-project` and cd into that directory.
Also, depending on the terminal emulator you use, you can make it always start what that script.
### Development
The development environment is built with Nix and Nix's Flakes, if you have it on your system then just run `nix develop` and you are ready to go. Other method is to build the Docker image based on provided Dockerfile:
```bash
docker build --tag tmux-session-wizard:dev --file ./Dockerfile .
```
To run the tests, just run `bats ./tests` for local development environment or `docker run --rm -it -u $(id -u):$(id -g) -v $PWD:$PWD -w $PWD tmux-session-wizard:dev bats ./tests` if you are using Docker.
There is also the helper script for it _./scripts/run-tests.sh_, run `./scripts/run-tests.sh -h` to get more information about usage.
