Been playing around with #fish_shell lately, and one thing I really like about it compared to bash, is that fish is very big on in-place expansion. Bash provides many shorthands for references to past commands (e.g., !$), or commonly used commands (aliases). However, these shorthands generally don't get expanded until the command is executed.

Conversely, fish's counterparts are expanded in-place on the command line. alt-up modifies the command prompt (vs bash's !$). abbreviations are expanded as soon as you add a whitespace (vs aliases).

It's neat.

It's time for a new blog article!

This time, I present some #tips and tricks for the #FishShell inspired by a recent video from Dreams of Code on Youtube.

I'm currently playing with #Codeium in #Vim, and am finding it interesting. It opens chats using a local browser port, sort of like the #fish_shell help command does. However, I can't find a CLI in #Homebrew (the AI may be hallucinating that there is one) or figure out how to make a whole-codebase query rather than getting context just from the current buffer.

Anyone tried it with Vim yet? How do I ask something like "please summarize what this codebase does" within Vim or at a shell prompt?

For anyone using the #fish_shell, the following #shell_function definition will let you switch to the latest CRuby #chruby knows about. It could be simplified (e.g. setting a function-local variable is mostly for debugging) or use builtins instead of pipes in shells where that matters, but I still find it useful for myself. Maybe you will, too.

```fish
function chruby-latest
set latest (
chruby | tr -d '*' |
pcregrep -o '\bruby-[\d.]+' | tail -1)
chruby $latest
end
```

There's been recent discussion about #POSIX & the #bash_shell. Some shells are awesome but don't even pretend to follow the POSIX standards. The #fish_shell is a good example.

Portability can be useful, but context matters too. Why deviate from standards? #LSB excludes #RubyLang but specifies #Perl & #PythonLang. #XDG is needlessly confusing. Distros may deviate from the #Linux #FHS because "reasons."

Goals & targets matter more than portability for its own sake.

Any #StarshipRS users out there? 🖥️ Just build my first preset and tested it accross #powershell, #fish_shell, #bash. Nice to have a consistant promt accross the different shells 😀
