I've sporadically seen the same CreateProcess failure in ninja recently that we'd been seeing for the GRD script [1]. This failure is related to the copy_devtools_modules script. As part of this change I've also corrected some linting errors that I had made with the previous fix. [1] The previous fix can be found at https://chromium-review.googlesource.com/c/devtools/devtools-frontend/+/1992319 Change-Id: Ic9a66160acddfc929fdd43f20572435ceff3724c Reviewed-on: https://chromium-review.googlesource.com/c/devtools/devtools-frontend/+/1997723 Commit-Queue: Robert Paveza <Rob.Paveza@microsoft.com> Reviewed-by: Lorne Mitchell <lomitch@microsoft.com> Reviewed-by: Tim van der Lippe <tvanderlippe@chromium.org>
DevTools Scripts
Development workflow scripts
These are scripts that can be useful to run independently as you're working on Chrome DevTools front-end.
The newer scripts such as for testing and hosted mode are written in Node.js, which has become the standard toolchain for web apps. The older scripts such as building (e.g. bundling and minifying) are written in Python, which has first-class support in Chromium's infrastructure.
Overview
Folders
- build - Python package for generating DevTools debug and release mode
- chrome_debug_launcher - automagically finds Chrome Canary and launches it with debugging flags (e.g. remote debugging port)
- closure - see section on Closure Compiler below
- gulp - experimental build process written in node.js & gulp to remove the dependency on Chromium-specific build tools (i.e. gn and ninja)
- hosted_mode - run DevTools on a localhost development server
- jsdoc_validator - enforces the use of Closure type annotations
Python Scripts
- compile_frontend.py - runs closure compiler to do static type analysis
- Note: the compiled outputs are not actually used to run DevTools
- lint_javascript.py - run eslint
- optimize_svg_images.py - manually run when changing svg images
Node.js scripts
The easiest way to run the node.js scripts is to use npm run which displays all the commands. For more information on the specific npm run commands, take a look at the primary devtools front-end readme (../readme.md).
Closure
DevTools manually rolls the closure compiler to ./closure. If you manually roll closure compiler, you will need to re-generate the closure_runner (in ./closure) and jsdoc_validator custom jars using the python scripts in their respective directory.
