Add simple markdown formatting to `rustc --explain` output This is a second attempt at #104540, which is #63128 without dependencies. This PR adds basic markdown formatting to `rustc --explain` output when available. Currently, the output just displays raw markdown: this works of course, but it really doesn't look very elegant. (output is `rustc --explain E0038`) <img width="583" alt="image" src="https://github.com/rust-lang/rust/assets/13724985/ea418117-47af-455b-83c0-6fc59276efee"> After this patch, sample output from the same file: <img width="693" alt="image" src="https://github.com/rust-lang/rust/assets/13724985/12f7bf9b-a3fe-4104-b74b-c3e5227f3de9"> This also obeys the `--color always/auto/never` command option. Behavior: - If pager is available and supports color, print with formatting to the pager - If pager is not available or fails print with formatting to stdout - otherwise without formatting - Follow `--color always/never` if suppied - If everything fails, just print plain text to stdout r? `@oli-obk` cc `@estebank` (since the two of you were involved in the previous discussion) |
