good first issue

I could give that a shot and let you know if I come up with anything! Super cool idea 😁 |

For syntax highlighting, see https://microsoft.github.io/monaco-editor/api/interfaces/monaco.editor.itextmodel.html#deltadecorations. We should not used the approximate monarch infra for this. |
1021: Wasm dependencies r=matklad a=detrumi As a first step towards running RA on WASM (see #1007), this tweaks the dependencies somewhat so that projects built using `wasm-pack` can use `ra_ide_api` as a dependency. There were two problems: - use of undeclared type or module `MmapInner` This error occurred because of the `memmap` crate, as a dependency of `fst` Solution: specify `default-features = false` for the `fst` package (see BurntSushi/fst#70) - use of undeclared type or module `imp` This happened in the `wait-timeout` crate ([which uses `Command` under the hood](alexcrichton/wait-timeout#18)), a dependency of `rusty-fork` which is a dependency of `proptest`. Solution: move `proptest` to dev-dependencies and add `#[cfg(test)]` to the `test_utils` crate. **Edit:** Oh, that causes trouble with resolving the import when running the tests. Hmm...

There's still an issue with the proptest dependency, I've opened proptest#137 and have a workaround branch here that can be used to patch |
|
I guess, just patching proptest in root EDIT: ... would work |

In the future we could just use https://devblogs.microsoft.com/visualstudio/intelligent-productivity-and-collaboration-from-anywhere/ |

We have wasm demo here now: https://github.com/rust-analyzer/rust-analyzer.github.io! I bet it can be greatly improved, but I don't have capacity to drive the improvements. If you have desire to tinker with WASM, feel free to hack on it how you see fit! |
It would be super cool to have a web-page which demoes rust-analyzer by running it with WASM. This could be a prototype of a WASM-powered rust-playground, which, for example, does syntax checking on the fly.
The MVP would probably be to compile ra to WASM and create a github page, with a text-area where you can edit rust code, and another text area where you see the syntax tree.
To make it really cool, we need to add Monaco editor with rust-analyzer powered syntax highlighting and simple completions support.
