Refactor: remove Rust CLI and implement Playwright repo generation in Starlark by benfdking · Pull Request #3 · quarylabs/rules_playwright

benfdking · 2026-05-17T18:42:58Z

Summary\nThis PR removes the Rust CLI/toolchain dependency and replaces its behavior with Starlark implementations.\n\n## What changed\n- Replaced Rust-driven browser target expansion and workspace file generation with \n- Rewired and to stop invoking CLI binaries\n- Replaced Rust UnZip 6.00 of 20 April 2009, by Info-ZIP, with modifications by Apple Inc.

Please report bugs to Apple.

Usage: unzip [-Z] [-opts[modifiers]] file[.zip] [list] [-x xlist] [-d exdir]
Default action is to extract files in list, except those in xlist, to exdir;
file[.zip] may be a wildcard. -Z => ZipInfo mode ("unzip -Z" for usage).

-p extract files to pipe, no messages -l list files (short format)
-f freshen existing files, create none -t test compressed archive data
-u update files, create if necessary -z display archive comment only
-v list verbosely/show version info -T timestamp archive to latest
-x exclude files that follow (in xlist) -d extract files into exdir
modifiers:
-n never overwrite existing files -q quiet mode (-qq => quieter)
-o overwrite files WITHOUT prompting -a auto-convert any text files
-j junk paths (do not make directories) -aa treat ALL files as text
-C match filenames case-insensitively -L make (some) names lowercase
-X restore UID/GID info -V retain VMS version numbers
-K keep setuid/setgid/tacky permissions -M pipe through "more" pager
See "unzip -hh" or unzip.txt for more help. Examples:
unzip data1 -x joe => extract all files except joe from zipfile data1.zip
unzip -p foo | more => send contents of foo.zip via pipe into program more
unzip -fo foo ReadMe => quietly replace existing ReadMe if archive file newer command usage with unzip in \n- Replaced Rust command usage with hashing in \n- Removed Rust dependency/toolchain/crate-universe setup from \n- Removed Rust workspace and CLI source files (, , Rust files under )\n- Kept as exported data via \n- Updated bzl_library wiring for docs extraction\n\n## Validation\n- (repo root): build/analysis succeeds (no test targets defined at root)\n- ==================== Test output for //:test:
