Hey @smemsh, I think this generally makes sense to me but can you create an issue to track this and as a place for us to iron out the details? We ask for this in our contributing guidelines just so that we have an artifact separate from the code change about higher level design input. Cheers! |

@williammartin Apologies, figured it was too trivial to write a separate issue, didn't realize that was part of the workflow. Noted and done in #9627. |

The markdown output width seems too wide. For example for
gh pr view, it would be desirable to limit to 80 columns. This makes it more readable for some users that have a preference for narrower paragraphs.In #6016 the maxwidth was changed from 80 to 120. The current code appears to use
TerminalWidth()(pkg/iostreams/iostreams.go) which populates from termios (ieTIOCGWINSZ), but won't exceed the hardcoded value of 120 as set inWithWrap()(pkg/markdown/markdown.go).This patch adds an environment variable override,
$GH_MDWIDTH, similar to how$MANWIDTHis used to set the display width of man pages. The default remains at 120.Without the patch, my workaround is like so:
It seems like the tool should have its own setting rather than hardcode it. The other option would be to use a
gh configsetting, but the env var is really simple and obvious, and has precedent with other tools (likeman).Please apply, thanks.
