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 e1677148999a54c7f0927fc1f37cef37835b5548 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
Prior to this fix, self-insert would always wait for a new character.
Track in char_event what sequence generated the readline event, and then
if the sequence is not empty, insert that sequence.
This will support implementing the space binding via pure readline
functions.
Previously, tab-completion would move the cursor to the end of the current token, even
if no completion is inserted. This commit defers moving the cursor until we insert a completion.
Fixes#4124
If interactive, `complete` commands are highlighted like they would
be if typed. Adds a little fun contrast and it's easier to read.
Moved a function out of fish_indent to highlight.h
we now print --long options for ones I arbitrarily decided
are less likely to be remembered.
Also fixed the `--wraps` items at the end not being escaped
Most of our completion scripts are written using the short options
anyhow, and this makes it less likely the output will span several
lines per command
This reverts commit f7dac82ed601135754d0c65536f79d07d83e9fae from pull
request #6059.
As discussed in #6099, this caused a regression in some completions (eg
dd).
