Clanker is a minimalistic set of command prompts for fish.
First, install the package via cargo install clanker.
Then put this in your config.fish or somewhere that will be sourced, ensuring
that the location cargo installs to is in your PATH:
```fish function fish_prompt clanker-prompt end
function fishrightprompt clanker-right-prompt "$status" end
function fishtitle clanker-title "$" end ```
clanker-promptclanker-prompt takes no arguments and outputs the current username, hostname,
and compressed directory. Compression of the current working directory is as
expected - if in the current user's home directory, the prefix is substituted
with ~. If in another user's home directory, the prefix is substituted with
~USER. If there is more than one component in the path, all components but
the last are trimmed to one or two extended grapheme clusters. Components are
trimmed to two extended grapheme clusters if a) they begin with a . or b)
they begin with a ~ and also are the first component in the path - in other
words, when we did prefix shortening to ~USER/other/path/components.
clanker-right-promptclanker-right-prompt optionally takes the status of the last command as an
argument. If the status was provided and was nonzero, it is printed in red. In
addition, if the current directory is a git repository according to the
behavior when running git_repository_open_ext with
REPOSITORY_OPEN_FROM_ENV, the current branch or checkout out commit ID will
be printed. If there are changes that would show up in git status, this will
be indicated with a *.
clanker-titleclanker-title optionally takes the currently running program as an argument
and prints it along with the compressed current working directory.
