Hi,

First,

--8<---------------cut here---------------start------------->8---
$ guix package --shw=hello
guix package: error: shw=hello: unrecognized option
--8<---------------cut here---------------end--------------->8---

becomes

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix package --shw=hello
guix package: error: shw=hello: unrecognized option
hint: Did you mean `show'?
--8<---------------cut here---------------end--------------->8---

And second the ugly (introduced by ’option’hint):

--8<---------------cut here---------------start------------->8---
$ guix package -Z

--8<---------------cut here---------------end--------------->8---

is fixed:

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix package -Z
guix package: error: Z: unrecognized option
--8<---------------cut here---------------end--------------->8---


A corner case is still missing:

        $ ./pre-inst-env guix environment -ah-hoc hello
        guix environment: error: a: unrecognized option

where it could be nice to hint for.  But from my understanding, it is not possible with SRFI-37.


All the best,
simon

Hi,

zimoun <zimon.toutoune <at> gmail.com> skribis:

> * guix/scripts.scm (option-hint): Fix corner cases.

Applied!  I also reverted the change I made in
11f11d7ecb817d1421f8b5340bcced59396d8708, which addressed the
short-option problem you mention.

Thanks,
Ludo’.
