Ok, so I love fish in general and the original guy who was complaining before
was a bit rude, but I liked a few of his ideas. Namely that help should have a
consistent interface and it is currently kind of a mess.
I've been scouring the 'net when needing fish help and forgot why since it has
been so long. Not to mention googling "fish shell ..." is just as likely to
return seafood recipes, hahah.
Perhaps I have something misconfigured (2.1 on Ubuntu) but here are my results:
~＞help for
cat: : No such file or directory
cat: invalid option -- 'f'
Try 'cat --help' for more information.
cat: invalid option -- 'f'
... snip 20x ...
cat: cygstart: No such file or directory
cat: xdg-open: No such file or directory
help: Could not find a web browser.
Please set the variable $BROWSER to a suitable browser and try again.
Didn't work. I don't mind a web browser showing things, but I didn't ask for
that, and just expect it to work in any case. If I'm in a terminal, I'd expect
it to print to stdout unless I ask for something different. I tried it on my
linux console/ssh also, same error... not sure what we're thinking looking for
a
browser in those environments?
I shouldn't have to set a variable and forced to get help from a GUI browser.
What if my system is broken and I'm trying to fix it?
~＞fish_config
Web config started at 'http://localhost:8001/'. Hit enter to stop.

^C
Shutting down.
This did work and found my browser, so there is some inconsistency somewhere.
Must be using different code.
I notice that fish isn't consistent with --help either:
- echo <nl> # prints a nl
- echo --help # prints help :)
- for <nl> # prints errors, then help, repopulates cmd-line
- for --help # prints errors, then help, repopulates cmd-line
- while <nl> # prints errors, then help, repopulates cmd-line
- while --help # gets stuck, needs ^C to escape
TL;DR Would be nice if fish could...
- Give help on builtins as well with the help command,
- perhaps default output to the terminal its in,
- unless a switch was given to use the browser
- unless that fails, fall back to terminal, perhaps with warning
- Have builtins recognize --help, skipping errors, as most external commands do.
- Consolidate all help code into a single function or module to ensure it is
consistent everywhere.
Thanks for reading,
