When we insert characters that don't yet have highlighting, we use the
highlighting to the left, unless there is nothing to our left. The logic to
check if we are the leftmost character uses an overly loose comparison. Let's
make it more specific.
No functional change.
When there are multiple event handlers for a single event, we would print
the same log statement twice. Let's add the function name to make this
less confusing.
I often hit Shift-Return accidentally, which makes my terminal echo a
weird escape sequence. Traditionally, terminals interpret Shift-Return
as Return, so let's follow that behavior. Analoguous to commit 1dc526884
(Bind Shift+Space CSI u sequence to Space, 2022-04-24).
Went by the docs at https://yarnpkg.com/cli/install.
Anything not in the sidebar was removed.
(also rename "upgrade" to "up" because that's a great idea)
See #9375.
This would print
```
abbr -a -- dotdot --regex ^\\.\\.+\$ --function multicd
```
which expands "dotdot" to "--regex ^\\.\\.+\$...".
Instead, we move the name to right before the replacement, and move
the `--` before that:
```
abbr -a --regex ^\\.\\.+\$ --function -- dotdot multicd
```
It might be possible to improve that, but this at least round-trips.
Historical behavior is to stop option parsing at the first non-option argument.
Since we have added more options, it seemed impractical to keep that behavior.
However people are using options in their abbr expansions ("abbr e emacs
-nw"). To support this, we ignore options. However, we only ignore them
if they are not valid "abbr" options. Let's ignore all options in the
expansion definition, which is a small price to pay to keep most existing
configurations working.
Fixes#9410
This does not fix other cases which used to work, like
abbr x -unknown
Those are hopefully not used by anyone, so I don't think we need to maintain
support for that.
Enhances abbreviations with extra features
- global abbreviations
- trigger on regex match as alternative to literal match
- the ability to expand abbreviations with a user-defined function
- the ability to set cursor position after expansion
Also default the marker to '%'. So you may write:
abbr -a L --position anywhere --set-cursor "% | less"
or set an explicit marker:
abbr -a L --position anywhere --set-cursor=! "! | less"
This renames abbreviation triggers from `--trigger-on entry` and
`--trigger-on exec` to `--on-space` and `--on-enter`. These names are less
precise, as abbreviations trigger on any character that terminates a word
or any key binding that triggers exec, but they're also more human friendly
and that's a better tradeoff.
set-cursor enables abbreviations to specify the cursor location after
expansion, by passing in a string which is expected to be found in the
expansion. For example you may create an abbreviation like `L!`:
abbr L! --position anywhere --set-cursor ! "! | less"
and the cursor will be positioned where the "!" is after expansion, with
the "| less" appearing to its right.
This adds support for the `--function` option of abbreviations, so that the
expansion of an abbreviation may be generated dynamically via a fish
function.
