A couple of optimizations are done in this PR. One, we now will check config ahead of time to see if a module is disabled before running any module code. Also, we won't try to discover a git repository unless the module requests access to it.
Git branches can become very long (e.g. gitlab auto-generated branch
names), thus it would be nice to be able to truncate them to keep your
prompt lenght in line.
This patch adds two new options to the git_branch module:
* truncation_length: The amount of graphemes to of a gitbranch to
truncate to
* truncation_symbol: The symbol that should be used to indicate that a
branch name was trunctated
To be able to correctly work with UTF-8 graphemes, unicode-segmentation
was added as a dependency.
• Add support for the disabled configuration option
This will allow you to selectively disable modules that you don't want or need. 😄
• Overwrite starship configuration file path with STARSHIP_CONFIG environment variable
• Write tests for the two configuration options that are available
- Create `Config` struct that is added to `Context` when initialized
- Read `~/.confg/starship.toml` during initialization (can be updated later to also look at `$XDG_CONFIG_HOME`)
- `Context` now has a method for creating modules. This allows us to provide modules with a reference to the configuration specific to that module
