# Helper script to be able to build on remote repos using git to push local changes
# (e.g. particularly helpful to target a remote windows build system)
#
# Typical windows remote git config looks like this:
#
#[remote "windows-pa"]
#        url = jdoe@desktop-foo:C:/Users/Jdoe/code/ollama
#        fetch = +refs/heads/*:refs/remotes/windows-pa/*
#        uploadpack = powershell git upload-pack
#        receivepack = powershell git receive-pack
#

# TODO - add argpare and make this more configurable 
# - force flag becomes optional
# - generate, build or test ...

# Note: remote repo will need this run once:
# git config --local receive.denyCurrentBranch updateInstead
repo = Repo(".")

# On linux, add links in /usr/local/bin to the go binaries to avoid needing this
# GoCmd = "/usr/local/go/bin/go"
