# 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`
## wgpu_sync.js
`wgpu_sync.js` streamlines updating `deno_webgpu` from
[gfx-rs/wgpu](https://github.com/gfx-rs/wgpu/).
It essentially vendors the `deno_webgpu` tree with a few minor patches applied
on top, somewhat similar to `git subtree`.
1. Update `COMMIT` or `V_WGPU` in `./tools/wgpu_sync.js`
2. Run `./tools/wgpu_sync.js`
3. Double check changes, possibly patch
4. Commit & send a PR with the updates
