# Fish Shell Functions and Abbreviations for Neovim Configuration Management

# Author: zx0r
# Description: A set of Fish shell functions and abbreviations to manage and switch between multiple Neovim configurations.
# Version: 1.0

# Overview:
# These functions and abbreviations simplify the process of managing multiple Neovim configurations.

# They allow you to:
# 1. Use `v` as an alias for `nvim`.
# 2. Use `vi` to launch Neovim with a specific configuration profile.
# 3. Use `ns` (via `nvim_switch_config`) to interactively switch between Neovim configurations.

# Prerequisites:
# - Fish shell installed.
# - Neovim installed.
# - Bob version manager for neovim
# - Multiple Neovim configurations stored in `$XDG_CONFIG_HOME/nvim-profiles`

# Functions and Abbreviations:

# 1. `v` - Alias for Neovim
# Description: A simple alias for launching Neovim.
# Usage: `v <file>`
function v --wraps=nvim --description 'alias v=nvim'
    nvim $argv
end

# 2. `vi` - Launch Neovim with a Specific Profile
# Description: Launches Neovim with a predefined configuration profile (`nvim-x0r`).
# Usage: `vi <file>`
function vi --wraps=nvim --description 'alias vi=#env NVIM_APPNAME=$config nvim $argv'
    set -l profile nvim-x0r
    set -l appname nvim-profiles/$profile
    set -gx NVIM_APPNAME $appname
    nvim $argv
end

# 3. `nvim_switch_config` - Interactive Neovim Configuration Switcher
# Description: Allows you to interactively select and switch between Neovim configurations using `fzf`.
# Usage: `ns <file>`
function nvim_switch_config --wraps=nvim --description 'alias ns=#env NVIM_APPNAME=$config nvim $argv'
    # Discover specific Neovim configurations
    set -l profiles (fd --max-depth 1 --glob '*nvim*' $XDG_CONFIG_HOME/nvim-profiles | xargs -n 1 basename)
    set -l config (printf "%s\n" $profiles | fzf --prompt=" Neovim Config > " --height=50% --layout=reverse --border --exit-0)
    set -l profile nvim-profiles/$config

    # Check if no configuration is selected
    if test -z "$config"
        echo "No profile selected."
        return 0
    end

    # Check for the default configuration
    if test "$config" = default
        set -l config ""
    end

    # Set the NVIM_APPNAME environment variable and launch Neovim
    set -gx NVIM_APPNAME $profile
    nvim $argv
end

# Abbreviation for `nvim_switch_config`
# Description: Shortcut for `nvim_switch_config`.
# Usage: `ns <file>`
abbr -a ns nvim_switch_config

# Notes:
# - Ensure `fd` and `fzf` are installed for the `nvim_switch_config` function to work.
# - Neovim configurations should be stored in `$XDG_CONFIG_HOME/nvim-profiles` (e.g., `~/.config/nvim-profiles/`).
# - The `NVIM_APPNAME` environment variable is used to specify the configuration profile.

# Example Neovim Profiles:
# - `nvim-profiles/nvim-x0r`: Custom configuration for zx0r.
# - `nvim-profiles/default`: Default Neovim configuration.

# Example Usage:
# 1. Open a file with the default Neovim configuration:
#    v myfile.txt
# 2. Open a file with the `nvim-x0r` configuration:
#    vi myfile.txt
# 3. Interactively switch Neovim configurations and open a file:
#    ns myfile.txt

# Fish Shell Functions for Neovim Configuration Management and Issue Reproduction

# Author: folke
# Description: A set of Fish shell functions to manage Neovim configurations, reproduce issues, and install new profiles.
# Version: 1.0

# Overview:
# These functions simplify the process of:
# 1. Reproducing Neovim issues by fetching and running Lua scripts from GitHub issues.
# 2. Switching between multiple Neovim configurations.
# 3. Installing and cleaning Neovim profiles.

# Prerequisites:
# - Fish shell installed.
# - Neovim installed.
# - GitHub CLI (`gh`) installed for issue fetching.
# - `fzf` installed for interactive profile selection.
# - Git installed for profile installation.

# Functions:

# 1. `repro` - Reproduce Neovim Issues
# Description: Fetches and runs Lua scripts from GitHub issues for debugging.
# Usage: `repro <issue-number>`
function repro -a issue
    if test -z "$issue"
        echo "Usage: repro <issue>"
        return 1
    end
    set file ./debug/$issue.lua

    # Fetch the issue if it doesn't exist
    if not test -f $file
        echo "Fetching issue #$issue"
        gh issue view $issue | sed -n '/```[Ll]ua/,/```/p' | sed '1d;$d' >$file
    end

    # Use local lazy and plugins
    set -x LAZY_PATH ~/projects/lazy.nvim

# Description: Allows switching between Neovim configurations interactively or by specifying a profile.
# Usage: `nvims [profile] [file]`
function nvims --wraps nvim
    set -l profile $argv[1]

    # Check if the provided profile exists
    if test -n "$profile" -a -d ~/.config/nvim-profiles/"$profile"
        set args $argv[2..-1]
    else
        # Use fzf to allow the user to select a profile

    and rm -rf ~/.cache/nvim-profiles/$profile
end

# Autocomplete profiles for the `nvims` function
complete -f -c nvims -a '(command ls ~/.config/nvim-profiles/)'

# Notes:
# - Ensure `gh`, `fzf`, and `git` are installed for full functionality.

#    repro 123
# 2. Switch to a specific Neovim profile:
#    nvims my-profile
# 3. Interactively select a Neovim profile:
