A cargo plugin for serving rust and crate doc locally.
```
$ cargo docs --help
Usage: cargo docs [OPTIONS] [EXTRA_ARGS]...
Arguments:
[EXTRA_ARGS]... Passthrough extra args to `cargo doc`
Options:
--host <HOST> Set host [env: HOST=] [default: 127.0.0.1]
-p, --port <PORT> Set port [env: PORT=] [default: 8080]
-r, --random-port Use random port [env: CARGO_DOCS_RANDOM_PORT=true]
-s, --search <ITEM> Search for item
-d, --dir <DIR> Serve directory content [env: DIR=]
-c, --manifest-path <MANIFEST_PATH> Crate manifest path [default: Cargo.toml]
-w, --watch Re-generate doc on change [env: CARGO_DOCS_WATCH=]
-o, --open Open in browser [env: CARGO_DOCS_OPEN=true]
-b, --book Serve rust book and std doc instead
-h, --help Print help information
-V, --version Print version information
```
By default, it will call `cargo doc` to build crate doc and start a local server.
Add `--book` option to see rust doc instead.
## Install
```
$ cargo install cargo-docs
```
## Examples
Serve crate doc on random port and open in browser
```
$ cargo docs -ro
[INFO] Serving crate doc on http://127.0.0.1:45669
[INFO] Opening http://127.0.0.1:45669
```
Same as above plus automatically rebuild and reload on file changes.
```
$ cargo docs -row
[INFO] Listening for changes...
[INFO] Serving crate doc on http://127.0.0.1:45669
[INFO] Opening http://127.0.0.1:45669
```
Serve rust docs instead (roughly the same as [`cargo-book`](https://crates.io/crates/cargo-book))
```
$ cargo docs -bro
[INFO] Serving rust doc on http://127.0.0.1:46661
[INFO] Opening http://127.0.0.1:46661
```
Search for `SocketAddr` in rust std doc served on random port and open it in browser
```
$ cargo docs -bros SocketAddr
[INFO] Serving rust doc on http://127.0.0.1:40143
[INFO] Opening http://127.0.0.1:40143/std/?search=SocketAddr
```
## Pro Tips
Passthrough `cargo doc` options after --
```
$ cargo docs -- --quiet
[INFO] Running cargo doc --quiet
[INFO] Serving crate doc on http://127.0.0.1:8080
```
If you are on WSL2, set `BROWSER=/mnt/c/Path/To/Your/Browser.exe` environment variable to open in desktop browser
```
$ export BROWSER="/mnt/c/Program Files/Firefox Nightly/firefox.exe"
```
Tired of typing `-o`, `-ro`, `-row`? Try these environment variables to save you some key strokes.
```
$ export CARGO_DOCS_OPEN=true
$ export CARGO_DOCS_WATCH=true
$ export CARGO_DOCS_RANDOM_PORT=true
```
