This prefers `-s` to `-v` - we have a *lot* more uses of `command -s`, it's the easier
mnemonic *and* the more compatible-with-fish option.
Also we don't really need the separate section that explains what
these options do *again*.
This can be bound like `bind \cl clear-screen`, and is, by default
In contrast to the current way it doesn't need the external `clear`
command that was always awkward.
Also it will clear the screen and first draw the old prompt to remove
flicker.
Then it will immediately trigger a repaint, so the prompt will be overwritten.
This was the remaining immediately actionable part of #7375.
It's not definitely the last word, but a change here would require a
bigger plan.
Fixes#7375
This used to print all codepoints outside of the ASCII range (i.e.
above 0x80) in \uXXXX or \UYYYYYYYY notation.
That's quite awkward, considering that this is about keys that are
being pressed, and many keyboards have actual symbols for these on
them - I have an "ö" key, so I would like to use `bind ö` and not
`bind \u00F6`. So we go by iswgraph.
On a slightly different note, `\e` was written as `\c[ (or \e)`. I do
not believe anyone really uses `\c[` (the `[` would need to
be escaped!), and it's confusing and unnecessary to even mention that.
During development, for a while `path change-extension` would return 0
when it found an extension to change.
This was later changed to returning 0 if there are any path arguments.
Neither of which is *super* useful, I admit, but we've picked one and
the docs shouldn't contradict it.
This was accidentally changed in 3.2.0, when type was made a builtin.
Since it's been 4 releases and nobody has noticed, rather than
breaking things again let's leave it as it is, especially because the
option is named "--no-functions", not "--no-functions-or-builtins".
After accidentally running a command that includes a pasted password, I want
to delete command from history. Today we need to recall or type (part of)
that command and type "history delete". Let's maybe add a shortcut to do
this from the history pager.
The current shortcut is Shift+Delete. I don't think that's very discoverable,
maybe we should use Delete instead (but only if the cursor is at the end of
the commandline, otherwise delete a char).
Closes#9454
This isn't the same as "join"/"join0", where one is just a special
case of the other.
These are two different, if basically opposite commands.
But more importantly this was a huge mess and the formatting was broken.
Keeps the location of original function definition, and also stores
where it was copied. `functions` and `type` show both locations,
instead of none. It also retains the line numbers in the stack trace.
This keeps tripping people up. We can't mention it *everywhere*, but
lets see if it works just in "match", since that sees to be where
people hit it most.
This now means `abbr --add` has two modes:
```fish
abbr --add name --function foo --regex regex
```
```fish
abbr --add name --regex regex replacement
```
This is because `--function` was seen to be confusing as a boolean flag.
This committed the sin of introducing a concept by giving it two
names:
> An alias, or wrapper, around ``ls`` might look like this
The term "wrapper" doesn't pull its weight here. It's simpler to just
call them aliases throughout. We do use "a simple wrapping function"
in another place, but that's to define "alias", not as a separate name.
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.
Prior to this change, abbreviations were stored as fish variables, often
universal. However we intend to add additional features to abbreviations
which would be very awkward to shoe-horn into variables.
Re-implement abbreviations using a builtin, managing them internally.
Existing abbreviations stored in universal variables are still imported,
for compatibility. However new abbreviations will need to be added to a
function. A follow-up commit will add it.
Now that abbr is a built-in, remove the abbr function; but leave the
abbr.fish file so that stale files from past installs do not override
the abbr builtin.
It's fine if it doesn't show up in the synopsis above, but putting it
under "Notes" is just too awkward.
It's a short option that exists, and so it should be documented.
I tried to make the synopsis a little less theoretical with
the placeholders and instead introduced the actual scope
options, long and short once, then refer to them as -Uflg from
then on.
I mentioned that list indicies are accepted / work to erase stuff.
In the list of options, we pretend like --unexport is long-only.
Especially with --unpath and --path, and what would go wrong
if one confused it with --univeral, and how rarely it's used,
I think it's better this way. I mention it as a synonym later
in the document so that it's not literally undocumented.
Changed phrasing such as:
"Causes the specified shell variable to be given a global scope"
Which can be read as we are taking a shell variable that exists
and giving it global scope, upgrading it to global (retaining
the value).
Redid the example section using the > syntax for things entered
into a prompt, with shell output following. The explanatory
Added in missing newlines at the ends of sentences.
Makes it possible to retrieve the currently executing command line as
opposed to the currently executing command (`status current-command`).
Closes#8905.
There are many applications with "primitive" argument parsing capabalities that
cannot handle munging two short options together (`-xf` for `-x -f`) or a short
option and its required value (`-dall` for `-d all`). To prevent fish from
suggesting munged arguments/payloads, the options (both long and short, not just
long!) can be specified as `-o` or `--old-option` but none of this is
documented.
This makes it so we link to the very top of the document instead of a
special anchor we manually include.
So clicking e.g. :doc:`string <cmds/string>` will link you to
cmds/string.html instead of cmds/string.html#cmd-string.
I would love to have a way to say "this document from the root of the
document path", but that doesn't appear to work, I tried
`/cmds/string`.
So we'll just have to use cmds/string in normal documents and plain
`string` from other commands.
