#
# Modified by nexB on October 2016:
#  - rework the handling of environment variables.
#  - made the script use functions
#  - support only Appveyor loading its environment variable to craft IRC notices.
#
# Modified by isis agora lovecruft <isis@torproject.org> in 2018:
#  - Make IRC server configurable.
#  - Make bot IRC nick deterministic.
#  - Make bot join the channel rather than sending NOTICE messages externally.
#  - Fix a bug which always caused sys.exit() to be logged as a traceback.
#  - Actually reset the IRC colour codes after printing.
#
# Modified by Marcin Cieślak in 2018:
#  - Accept UTF-8
#  - only guess github URLs
#  - stop using ANSI colors
#
# Modified by teor in 2018:
#  - fix github provider detection ('gitHub' or 'gitHubEnterprise', apparently)

"""Simple AppVeyor IRC notification script.

The first argument is an IRC server and port; the second is the channel. Other
arguments passed to the script will be sent as notice messages content and any
{var}-formatted environment variables will be expanded automatically, replaced
with a corresponding Appveyor environment variable value. Use commas to
delineate multiple messages.


Example:
export APPVEYOR_URL=https://ci.appveyor.com
export APPVEYOR_PROJECT_NAME=tor
export APPVEYOR_REPO_COMMIT_AUTHOR=isislovecruft
export APPVEYOR_REPO_COMMIT_TIMESTAMP=2018-04-23
export APPVEYOR_REPO_PROVIDER=gihub
export APPVEYOR_REPO_BRANCH=repo_branch
export APPVEYOR_PULL_REQUEST_TITLE=pull_request_title
export APPVEYOR_BUILD_VERSION=1
export APPVEYOR_REPO_COMMIT=22c95b72e29248dc4de9b85e590ee18f6f587de8
export APPVEYOR_REPO_COMMIT_MESSAGE="some IRC test"
export APPVEYOR_ACCOUNT_NAME=isislovecruft
export APPVEYOR_PULL_REQUEST_NUMBER=pull_request_number
export APPVEYOR_REPO_NAME=isislovecruft/tor
python ./appveyor-irc-notify.py irc.oftc.net:6697 tor-ci '{repo_name} {repo_branch} {short_commit} - {repo_commit_author}: {repo_commit_message}','Build #{build_version} passed. Details: {build_url} |  Commit: {commit_url}
