excerpt: A side effect of fancier help text

*(This change will be in the upcoming v0.11.0 release)*
|

|
As part of the effort to polish the lnav TUI, I wanted to make the builtin
|
||
|
|
help text look a bit nicer. The current help text is a plain text file with
|
||
|
|
some ANSI escape sequences for colors. It's not easy to write or read. Since
|
||
|
|
Markdown has become a dominant way to write this type of document, I figured
|
||
|
|
I could use that and have the side benefit of allowing lnav to read Markdown
|
||
|
|
docs. Fortunately, the [MD4C](https://github.com/mity/md4c) library exists.
|
||
|
|
This library provides a nice event-driven parser for documents instead of
|
||
|
|
just converting directly to HTML. In addition, document structure is now
|
||
|
|
shown/navigable through the new breadcrumb bar at the top. I think the
|
||
|
|
result is pretty nice:

## Viewing Markdown Files
|
||
|
|
|
||
|
|
Files with an `.md` suffix will be considered as Markdown and will be
|
||
|
|
parsed as such. As an example, here is lnav displaying its README.md file:
|
||
|
|
|
||
|
|
<script id="asciicast-iw4rwddZNGCe3v8DyOfItERG9"
|
||
|
|
src="https://asciinema.org/a/iw4rwddZNGCe3v8DyOfItERG9.js"
|
||
|
|
async>
|
||
|

</script>
