pick-patch

Help you cherry pick patches from Gerrit server

Installation

pip install pick-patch

Configuration

1. Get user name and http password in gerrit setting webpage (ex. https://review.gerrithub.io/settings/#HTTPCredentials)
2. Add user name and http password in ~/.netrc (ex. machine review.gerrithub.io login susu9 password XXXOOOXXXOO)
3. Now you are good to go. (script parses ~/.netrc by default)

Custimization

You can create a config file in ~/.pickrc to customize your preference

# Supported configurations and format

password = XXXOOOXXXOO
gerritUrl = https://review.gerrithub.io
connectTimeout = 30
fetchProtocols = http ssh git
netrcPath = ~/.netrc

delimiterEnd = ********************
patchPreview = git log --oneline -1

Features
