#!/usr/bin/env bash

# Semi automatic scripted workflow to update existing R feedstocks
#
# Sometimes the suggested updates from the bot are not enough, instead a diff
# against a new skeleton run supports fully updating a recipe.
#
# 0. Make the editor of your choice available inside 'git gui', e.g.
#   * git config --global guitool.atom.cmd atom\ \$FILENAME
#   * git config --global guitool.gedit.cmd gedit\ \$FILENAME
# 1. Put the name of the package(s) to update in packages.txt
# 2. Ensure you forked all package feedstocks already
# 3. Run this script via: ./update.sh $your_github_username
# 4. Do the update commit (git gui will be started):
#   * Carefully select all lines required for the update commit
#   * Open a file via the specified editor in git gui for manual changes,
#     e.g build number
#   * Do the update commit and close git gui
# 5. Rerender commit is done automatically, push is done after confirmation
# 6. Browser is opened to create PR on GitHub from your fork to the conda-forge
#    feedstock
# ... Next package ... repetition of step 4.-6.
