This PR _**temporarily**_ removes WebGPU (which has behind the `--unstable` flag in Deno), due to performance complications due to its presence. It will be brought back in the future; as a point of reference, Chrome will ship WebGPU to stable on 26/04/2023. --------- Co-authored-by: Bartek Iwańczuk <biwanczuk@gmail.com>

# 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:
|
||
|
||
```sh
|
||
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:
|
||
|
||
```sh
|
||
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
|
||
|
||
```sh
|
||
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_:
|
||
|
||
```sh
|
||
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.
