Running `tools/wpt.ts` with a filter would cause an error if there were extra, leftover expectations in expectations.json. These errors would not appear if no filter was passed, often leaving the filtered version of the test runner broken. This also introduces a smarter bit of logic where filters can be specified with a leading slash (`tools/wpt.ts run -- /url` is equivalent to `tools/wpt.ts run -- url`) |

Tools
Documentation for various tooling in support of Deno development.
format.js
This script will format the code (currently using dprint, rustfmt). It is a prerequisite to run this before code check in.
To run formatting:
deno run --allow-read --allow-write --allow-run --unstable ./tools/format.js
lint.js
This script will lint the code base (currently using dlint, clippy). It is a prerequisite to run this before code check in.
To run linting:
deno run --allow-read --allow-write --allow-run --unstable ./tools/lint.js
Tip: You can also use cargo to run the current or pending build of the deno executable
cargo run -- run --allow-read --allow-write --allow-run --unstable ./tools/<script>
flamebench.js
flamebench.js facilitates profiling and generating flamegraphs from
benchmarks.
General usage:
❯ ./tools/flamebench.js
flamebench <bench_name> [bench_filter]
Available benches:
op_baseline
ser
de
To profile the op_baseline bench, run ./tools/flamebench.js op_baseline,
this will run all 3 benches in `op_baseline.
Often when profiling/optimizing, you'll want to focus on a specific sub-bench,
flamebench supports a bench/test filter arg like the regular cargo commands.
So you can simply run ./tools/flamebench.js op_baseline bench_op_async or
./tools/flamebench.js op_baseline bench_op_nop to profile specific benches.
Tip: the [bench_filter] argument doesn't have to be an exact bench name, you
can use a shorthand or a partial match to profile a group of benches, e.g:
./tools/flamebench.js de v8
copyright_checker.js
copyright_checker.js is used to check copyright headers in the codebase.
To run the copyright checker:
deno run --allow-read --allow-run --unstable ./tools/copyright_checker.js
Then it will check all code files in the repository and report any files that are not properly licensed.
