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).

* docs: Add "Writing your own prompt" doc
* Remove a space from the "output"
* some teensy adjustments
* Address feedback
* envvar one more PWD
* More html warning
This was always extremely weasel-wordy and I have no idea which one
here is a good choice.
OMF is basically inactive at this point, so we might be doing people a
disservice by linking to it.
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.
This prevents leaking the escape sequence by printing nonsense, and it
also allows disabling cursor setting by just setting the variable to
e.g. empty.
And if we ever added any shapes, it would allow them to be used on new
fish and ignored on old
Fixes#9698
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 allows linking them from elsewhere (currently fish_indent) and
also improves the formatting - the code formatting here isn't actually a good look.
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 reads nicer to not have the "see also" thing right in the first
paragraph. I'm not even done reading this, why are you sending me
elsewhere?
(of course if it's a hotlink on a specific word that's different)
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.
I'm not sure if line continuations are covered anywhere else in the docs, but I
think the escapes section of the language page is a good place to mention them.
Makes it possible to retrieve the currently executing command line as
opposed to the currently executing command (`status current-command`).
Closes#8905.
- Clean up the wording a little.
- Highlight the limitations of the "debugger" more clearly and don't mislead
people into thinking it's possible to really interactively set/remove
breakpoints except in select circumstances.
Sidenote: I can't believe we're using a markup language that doesn't support
nested inline markup. What a crying shame, rST!
Up to now, in normal locales \x was essentially the same as \X, except
that it errored if given a value > 0x7f.
That's kind of annoying and useless.
A subtle change is that `\xHH` now represents the character (if any)
encoded by the byte value "HH", so even for values <= 0x7f if that's
not the same as the ASCII value we would diverge.
I do not believe anyone has ever run fish on a system where that
distinction matters. It isn't a thing for UTF-8, it isn't a thing for
ASCII, it isn't a thing for UTF-16, it isn't a thing for any extended
ASCII scheme - ISO8859-X, it isn't a thing for SHIFT-JIS.
I am reasonably certain we are making that same assumption in other
places.
Fixes#1352
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.
