proj

TODO

• Actually spawn the shell

• Figure out why the pre-spawn hook is using the project_dir value

Usage

Invoke the script and pass the name of the project as its only non-flag argument:

proj learncpp

If the project exists in your project directory, it will spawn a subshell in that directory. Advanced usage and hooks are detailed below, but you can use it as a glorified cd if that's all you need.

Behavior

When invoked as specified in usage (with any number of valid flags plus exactly one non-flag argument referred to here as $arg1), proj will do the following:

• Check for the existence of project_dir

  • If project_dir is a directory or symbolic link to one, proceed

  • If project_dir is any other type of file, panic

  • If project_dir does not exist, create it

• cd to project_dir (normally ~/Projects)

• Check for the existence of $arg1

  • If $arg1 is a directory or symbolic link to one, proceed

  • If $arg1 is any other type of file, panic

  • If $arg1 does not exist, then:

    • Execute the pre-create hook if configured to do so

    • Create $arg1 as a directory

    • Execute the post-create hook if configured to do so

• cd to $arg1

• Execute a subshell, and

  • Source .projenv if configured to do so

  • Execute $SHELL

Flags

flag	description	args
-c	Path to a config file to load in place of the default (~/.config/proj.conf)	Path to config file
-h	Print basic help text

Configuration

value	description	default
hook_pre_create	Path to a script invoked (not sourced) before a project is created. Script will be executed relative to project_dir	Empty string
hook_post_create	Path to a script invoked (not sourced) after a project is created. Script will be executed relative to the project's root directory	Empty string
hook_pre_spawn	Path to a script invoked (not sourced) before a shell is spawned in the project directory. Script will be executed relative to the project's root directory	Empty string
hook_env	Path to a script to source in after entering a project directory but before a shell is spawned. Script will be sourced relative to the project's root directory	.projenv
project_dir	Path to where projects should be stored.	$HOME/Projects
