angle-validator

A working build is shipped in out/. Installation and (re)building is only necessary if modifying source.

Init and Build (Mac/Linux)

1. git clone https://github.com/brendankenny/angle-validator.git
2. cd angle-validator/
3. Download, install, and activate the Emscripten SDK

   git clone https://github.com/juj/emsdk.git
   ./emsdk/emsdk install latest
   ./emsdk/emsdk activate latest

4. git clone https://chromium.googlesource.com/angle/angle (TODO: lock version)
5. yarn build

Test

yarn test yarn lint yarn type-check

Update source list

Occasionally, the list of source files and compile flags will need to be regenerated as ANGLE is updated.

1. Check for changes to shader translator sample

   cd angle
   git fetch
   git diff origin/master -R -- samples/shader_translator/shader_translator.cpp
   git diff origin/master -R # optional, will be very large
   git pull # if desired
   cd ..

2. If update needed, initialize ANGLE

   cd angle
   python scripts/bootstrap.py
   gclient sync
   cd ..

3. yarn gen
4. Compare to checked-in build config (git diff build/build-config.json)
5. yarn build if ANGLE or build changes require it

Update test expectation binary

If ANGLE is updated, should update test expectation generator from ANGLE source.

1. yarn build --gt
