My Fish configuration

My personal fish prompt configuration. I prefer it on a black background but it can fit with other background colors.

Features

Mainly:

• Prompt using two lines
• Custom Git prompt using a nerdfont
• Add custom aliases for git and some CLIs with private aliases
• Add some useful functions like yupgrade (see ./functions directory)
• Handle environment configuration when needed (see the environments part)
• Handle private/local aliases, environment or configuration (see the private/local configuration part)

Environements

This configuration handle some environments if it found the related command (see ./env directory):

• [if nodenv installed] Initialize a Node environment using nodenv
• [if rbenv installed] Initialize a Ruby environment using rbenv
• [if pyenv installed] Initialize a Python environment using pyenv with virtualenv management (pyenv-virtualenv)
• [if go installed] Set Go environment variables
• [if mysql@5.7 installed] Set environment variables and CLIs paths for mysql@5.7

You can install all these packages if you use brew as a packages manager: brew install nodenv rbenv go pyenv pyenv-virtualenv mysql@5.7

Private / Local configurations

You can add private/local only configurations/environments/aliases if you need to. Just add a private.fish which will be ignored by git and won't be commited:

• in the root folder for a private fish configuration
• in the env/ folder for a private environment set up
• in the aliases/ folder for private aliases

How to install it? (macOS)

1. If it's not done yet, install fish using brew by doing brew install fish. Then run fish in your terminal to use the fish shell. This configuration need a recent fish version (v3.1+).

2. Install the nerdfont of your choice and use it in your terminal. As the prompt will use some special characters from these fonts, you will need it if you want to have all icons.

3. Put all the config files and folders (this repository content) in your ~/.config/fish folder. This latter should already be present if you've installed fish. You can also simply remove the original config folder and git clone like following:

   mv ~/.config/fish /tmp/
   git clone https://github.com/CPatchane/config-fish.git ~/.config/fish
   

4. Load your config by doing source ~/.config/fish (it should be run by default when opening a new shell with fish)
