Original Pull Request: https://github.com/microsoft/terminal/pull/2168

State: closed
Merged: Yes

Summary of the Pull Request

Adds a bx script that only builds the project in your current directory (and all the project's dependencies).

Detailed Description of the Pull Request / Additional comments

When we were in Windows, bz behaved a lot more like this, because obviously you don't want to build all of Windows when just working on the Console. However, when we moved the console to MsBuild, the solution only took like 4s to build, so we never bothered with creating a script to build a single project.

However, the Terminal projects take a very long time to build. So rebuilding the entire solution from the commandline became increasingly painful. This change should alleviate that pain. Hopefully quickly iterating on code in the Console codebase should be much more manageable with this change.

Building a single project in a solution is a little tricky however. You need to supply the target name to msbuild.exe, which is not as simple as just the Project's name or path. So we need to parse the sln's .metaproj file to correlate vcxproj file to target name. That's what bx.ps1 is for.

This change could use some extra love - generating the metaproj takes a little while, as does parsing it. There might be a way to only generate the metaproj if it's changed, I didn't really investigate this, but presumably it could be done with a powershell script. I'll leave that for another work item in the future. It's still much faster to build with bx than before, but it could be faster.

Validation Steps Performed

Built the thing using bx and bcx.
