Consider a group of short options, like -xzPARAM, where x and z are options and z takes an argument.
This commit enables completion of the argument to the last option (z), both within the same
token (-xzP) or in the next one (-xz P).
complete -C'-xz' will complete only parameters to z.
complete -C'-xz ' will complete only parameters to z if z requires a parameter
otherwise, it will also complete non-option parameters
To do so this implements a heuristic to differentiate such strings from single long options. To
detect whether our token contains some short options, we only require the first character after the
dash (here x) to be an option. Previously, all characters had to be short options. The last option
in our example is z. Everything after the last option is assumed to be a parameter to the last
option.
Assume there is also a single long option -x-foo, then complete -C'-x' will suggest both -x-foo and
-xy. However, when the single option x requires an argument, this will not suggest -x-foo.
However, I assume this will almost never happen in practise since completions very rarely mix
short and single long options.
Fixes#332
In e167714899 we allowed recursive calls
to complete. However, some completions use infinite recursion in their
completions and rely on `complete` to silently stop as soon as it is
called recursively twice without parameter (thus completing the
current commandline). For example:
complete -c su -s -xa "(complete -C(commandline -ct))"
su -c <TAB>
Infinite recursion happens because (commandline -ct) is an empty list,
which would print an error message. This commmit explicitly detects
such recursive calls where `complete` has no parameter and silently
terminates. This enables above completion (like before raising the
recursion limit) while still allowing legitimate cases with limited
recursion.
Closes#6171
This stops reading argument names after another option appears. It does not break any previous uses and in fact fixes uses like
```fish
function foo --argument-names bar --description baz
```
* `function` command handles options after argument names (Fixes#6186)
* Removed unneccesary test
Corrects #6110
BSD `seq` produces a down-counting sequence when the second argument is
smaller than the first, e.g.:
$ seq 2 1
2
1
$
While GNU `seq` produces no output at all:
$ seq 2 1
$
To accommodate for this behavior, only run `seq` when we are sure that
the second argument is greater than or equal to the first (in this case,
the second argument `line_count` should be greater than 1).
* Add completions/sfdx.fish
* completions/sfdx.fish: add completion for options
* completions/sfdx.fish: add a completion for --manifest(-x) option which need package.json
* completions/sfdx.fish: replace redundant function with already existing one
