Resolving dependencies

For hg blame, you need to install hglib: pip install python-hglib.

Installing

go get -u sourcegraph.com/sourcegraph/go-vcs/vcs

Implementation differences

The goal is to have all supported backends at feature parity, but until then, consult this table for implementation differences.

Development

First-time installation of protobuf and other codegen tools

You need to install and run the protobuf compiler before you can regenerate Go code after you change the vcs.proto file.

1. Install protoc, the protobuf compiler. Find more details in the protobuf README.

   On OS X, you can install it with Homebrew by running:

   brew install --devel protobuf
   

   Then make sure the protoc binary is in your $PATH.

2. Install gogo/protobuf.

   go get -u github.com/gogo/protobuf/...
   

3. Install gopathexec:

   go get -u sourcegraph.com/sourcegraph/gopathexec
   

Regenerating Go code after changing vcs.proto

go generate sourcegraph.com/sourcegraph/go-vcs/vcs/...

Running tests

Run go test ./vcs/....
