This document describes how to use the available configuration options to customize Fisherman.
## DESCRIPTION
Your fish user configuration, usually located in `$XDG_CONFIG_HOME`/fish/config.fish is updated after installing Fisherman to add the global variables `$fisher_home` and `$fisher_config`.
`$fisher_home` is the location where Fisherman was downloaded. This location can be anywhere you like. If you changed this location after installing Fisherman, you need to update `$fisher_home` as well.
`$fisher_config` is the user configuration directory and the location of your user *fishfile*, *cache* directory and where plugins get installed to. This location must be different from `$fisher_home`. The default location is `$XDG_CONFIG_HOME`/fisherman.
You can also customize the debug log path, cache location, index source url, command aliases, and other options via `$fisher_*` variables.
## VARIABLES
*`$fisher_home`:
The home directory. This is the path where you downloaded Fisherman.
*`$fisher_config`:
The user configuration directory. `$XDG_CONFIG_HOME`/fisherman by default. This directory is where the *cache*, *functions* and *completions* directories are located.
*`$fisher_cache`:
The cache directory. Plugins are first downloaded here and installed to `$fisher_config/functions` afterwards. The cache is `$fisher_config`/cache by default.
*`$fisher_index`:
Index source url or file. To use a different index set this to a file or url. Redirect urls are not supported due to security and performance concerns. The underlying request and fetch mechanism is based in `curl`(1). See also `fisher`(7)#{`Index`}.
*`$fisher_error_log`:
This file keeps a log of the most recent crash stack trace. `$fisher_cache`/.debug_log by default.
Use this variable to define custom aliases for fisher commands. See #{`Examples`} below.
*`$fisher_default_host`*host*
Use this variable to define your preferred git host. Fisherman uses this value to convert short urls like `owner/repo` to `https://host/owner/repo`. The default host is *github.com*.
