Or is there maybe a way to set the pager for all help related queries to some command? I’m using bat and would like to pipe all --help through | bat --language=help by default for the syntax highlighting and colored output… Or if you know a lower effort way to color the output of --help let me know.
Frankly, I would be surprised, if anything uses groff for displaying
--help, unless it shows the man page for that.The most basic implementation of
--helpis a manually formatted multi-line string written into the source code, which gets printed as-is.For dynamic layouting, you do need more logic, but rendering it to groff source code first does not make that easier. For tabbing, you print an appropriate number of
\t.
