# A nice FISH configuration



### Features 

* Very reluctant FISH file-name truncation

(you know, that thing where `/media/alexandra/code` becomes `/m/a/code`).

* Newline between status information and user input.

* So colorful that people will assume that you're queer.

* Lots and lots of comments to make it easier to understand & customize the code further.

* Indicators for current time, exit code of previous command, and disk usage, all with meaningful color cues.

* Prompt looks red and dangerous when logged in as root.

* Easy to override a lot of the code simply by creating `/etc/fish/override.fish` and `/etc/fish/interactive-override.fish`,

making it easy to do rudimentary customizations without too much worry about merging future updates.

* Optimized to be system-wide, so that you don't lose your pretty gay features when you `sudo -i`.

* Some useful abbreviations.

* An unobtrusive display of how long each previous command took, on the right side of the prompt.

* A `notify-send` notification for if a command that takes more than 10 seconds is finished. Note that this makes use of `xdotool` and `$WINDOWID` to detect if the window has focus or not. This feature has problems with terminal multiplexers, and I need to figure out a way around that. This may be eventually refactored using the serial method suggested by egmont [here](https://unix.stackexchange.com/a/480138/310093), or I might simply build some tmux hooks for importing `$WINDOWID`. 

* Reasonably light-weight. Can run on a small Raspberry Pi system comfortably.

### Prerequisites

* Fish shell (obviously).

* Perl.

* Perl Filesys::df (package name is `perl-filesys-df` on Arch, and `libfilesys-df-perl` on Debian OSes).

On systems like Cygwin it will _probably_ work [if you install via CPAN](https://stackoverflow.com/questions/10483574/how-do-i-install-perl-libraries-in-cygwin#10483795), but I have not yet tested that. (Someone please test this, as Cygwin compatibility is one of my goals with this project!)

* An environment that understands standard Unix commands.



### Installation

Just copy the .fish files from this repo to `/etc/fish`.

[An install script](https://raw.githubusercontent.com/alxpettit/fish/master/bin/fish-install.sh)

that pulls the files from the repo straight to your computer is included in this repo, if you're lazy like me.



(Note that this install script assumes you have `wget`!)



You can simply `wget "https://raw.githubusercontent.com/alxpettit/fish/master/bin/fish-install.sh" -O - | sudo sh -`,

if you're one of those people who likes to pipe directly to a root terminal off the internet.



For the paranoid (myself included) there are `.gpg` signitures for each FISH file,

which can be automatically checked before installation with [fish-secure-install.fish](https://raw.githubusercontent.com/alxpettit/fish/master/bin/fish-secure-install.fish).



Note that you will likely need local `~/.config/fish/config.fish` rc files that all simply `source /etc/fish/config.fish` for this to work,

as of this writing. (Hopefully the FISH team will fix this sometime soon.)



I have thus created a [fish-integrate.fish](https://raw.githubusercontent.com/alxpettit/fish/master/bin/fish-integrate.fish) script to automate that task.
