Fisher: 📌📚📕 Migration instructions from oh-my-fish to fisherman?

[FabioAntunes]

It's somehow related to https://github.com/fisherman/fisherman/issues/110 but I think that would be nice to have a migration guide, explaining how to migrate all the plugins and stuff from omf to fisherman.

[FabioAntunes]

So for those who are running the latest omf version, here are the steps:

:pushpin: Instructions

1. Just install fisherman

curl -Lo ~/.config/fish/functions/fisher.fish --create-dirs git.io/fisherman

2. If you happen to be also running any fisherman _before_ 2.0 alongside omf

curl -L git.io/fisher-up-me | fish

use curl -L git.io/fisher-up-me | fish_indent --ansi to inspect the script first if you like.

This will _not_ delete your configuration, but it will move the directory into a different name. You can then choose to start over _or_ copy the plugin directories back into the new ~/.config/fisherman.

3. Add omf plugin names to ~/.config/fish/fishfile and run fisher

Add the plugins manually oh-my-fish/plugin--<name-of-the-plugin> and for themes add oh-my-fish/theme--<name-of-the-theme>, to install the git flow plugin and theme agnoster we will add these two lines:

oh-my-fish/plugin-git-flow
oh-my-fish/theme-agnoster

then run fisher

If you are using the new omf version this script will add your omf plugins to the fisherman file and then installs them, if you are using the old omf version this script will only this only installs plugins, for themes you must add oh-my-fish/theme-<name-of-the-theme> to the fishfile

if test -f ~/.config/omf/bundle
  set bundle (cat ~/.config/omf/bundle)
  cd ~/.config/fish
  for plugin in $bundle
    set pluginName (echo $plugin |  sed "s/ /\n/g")

    if [ $pluginName[1] = "theme" ]
      set baseName "oh-my-fish/theme-"
    else if [ $pluginName[2] = "nvm" ]
      set baseName "fisherman/"
    else if [ $pluginName[2] = "bass" ]
      set "edc/"
    else
      set baseName "oh-my-fish/plugin-"
    end

    echo $baseName$pluginName[2] >> fishfile
  end
else
  cd ~/.config/fish
  for plugin in $OMF_CONFIG/*
    echo "$plugin" >> fishfile
  end
end
fisher

4. Remove omf directories and files

If you are using the new omf just run

omf destroy

Else you will have to remove it manually

rm -rf "$OMF_PATH" "$OMF_CONFIG"
$EDITOR ~/.config/fish/config.fish

### ERASE LINE   set -gx OMF_PATH "{{OMF_PATH}}"
### ERASE LINE   set -gx OMF_CONFIG "{{OMF_CONFIG}}"
### ERASE LINE   source $OMF_PATH/init.fish
