# How to run API comparison locally:
|
||
#
|
||
# 1. To compare a specific commit to the previous one, just run this script (./compare.sh).
|
||
# 2. Replicating what happens for a specific PR is a bit more complicated:
|
||
# a. Fetch the source code for that PR, using "git fetch --no-tags --progress https://github.com/xamarin/xamarin-macios +refs/pull/<PR>/*:refs/remotes/origin/pr/<PR>/*",
|
||
# so for example this for PR #4614:
|
||
#
|
||
# git fetch --no-tags --progress https://github.com/xamarin/xamarin-macios +refs/pull/4614/*:refs/remotes/origin/pr/4614/*
|
||
#
|
||
# b. Checkout the commit you want to compare (typically the branch you created the PR from if it's your own PR).
|
||
# i) This isn't 100% accurate, since GitHub will build a merged version
|
||
# of your branch + the target branch. If you want to test _exactly_
|
||
# the same code as GitHub, checkout the 'origin/pr/<merge>/merge'
|
||
# branch the previous git fetch command created.
|
||
#
|
||
# c. Execute 'ghprbPullId=4614 ./compare.sh'
|
||
#
