When adding a command to history, we first expand its arguments to see
if any arguments are paths which refer to files. If so, we will only
autosuggest that command from history if the files are still valid. For
example, if the user runs `rm ./file.txt` then we will remember that
`./file.txt` referred to a file, and then only autosuggest that if the file
is present again.
Prior to this change we only performed simple expansion relative to the
working directory. This change extends it to variables and tilde
expansion. For example we will now apply the same hinting for
`rm ~/file.txt`
Fixes#7582
This removes the 100 msec timeout from io_buffer_t. We no longer need to
periodically wake up to check if a command substitution is finished,
because we get explicitly poked when that happens.
io_buffer_t is used to buffer output from a command substitution, so we
can split it into arguments. Typically io_buffer_t reads from its pipe
until it gets EOF and then stops reading. However it may be that the
cmdsub ends but EOF is not delivered because the stdout of the cmdsub
escaped with a background process.
Prior to this change we would wake up every 100 msec (select timeout) to
check if the cmdsub is finished. However this 100 msec adds latency if a
background process is launched from e.g. fish_prompt.
Switch to the new poke() function. Now when the cmdsub is finished, it
pokes its item, which explicitly wakes it up. This removes the extra
latency.
Fixes#7559
In preparation for fixing #7559, add a function poke_item to fd_monitor.
fd_monitor has a list of file descriptors, and invokes a callback when an
fd becomes readable. With this change, we assign each item a unique ID and
return it when the item is added; the ID may then be used to invoke the
callback explicitly.
The idea is that we can stop reading from the pipe associated with the
cmdsub when the job is finished, even if the pipe is still open.
This adds a test to ensure that if a long running background process is
launched from a command substitution, that process does not cause the
cmdsub to hang. That could easily happen if we just wait for the pipe to
close; this is verifying that we are also checking for the job to complete.
This is mildly useful when activating virtualenvs. We had remove
these files earlier, but since there are no more false negatives from
__fish_complete_suffix it seems safe to re-add them.
0507b04 loosened the FreeBSD-only restriction on `pkg` completions to
!SunOS in order to support DragonFlyBSD. This is overly broad and can
still cause the script to be loaded on systems that we can't
realistically expect to have `pkg` be the FreeBSD pkgng package manager
(especially since `pkg` is a much more generic term when compared to the
likes of `dnf`, `yum`, `deb`, and `apt`).
This patch changes `pkg` + BSD to be the minimum requirements for
considering a system to be using pkgng.
This allows for multiple edits to be undone/redone in one go, as if they
were one edit.
Useful when a function is editing the commandline buffer via scripted
changes or via a keybinding so the internal changes to the buffer can be
abstracted away.
(Having extreme difficulty getting pexpect to play nice with the concept
of undo/redo...)
This removes the margin with the background gradient and such
completely once the screen falls under 700px. In those cases we really
don't want to waste space, and having just a weird blue bit above the
docs looks weirder than not having anything.
In e8b6705067 this was made to exit if
not on FreeBSD because Solaris has a tool called "pkg" that apparently
"isn't worth supporting".
Since at least DragonflyBSD also uses FreeBSD's pkg thing, let's turn
that check around.
There's a macOS bug with Source Code Pro that makes it unable to be
colored. Since that makes webconfig unusable, stop recommending it.
Instead, we just pick the default monospace font for the system.
Currently binding `exit` to a key checks too late that it's exitted,
so it leaves the shell hanging around until the user does an execute
or similar.
As I understand it, the `exit` builtin is supposed to only exit the
current "thread" (once that actually becomes a thing), and the
bindings would probably run in a dedicated one, so the simplest
solution here is to just add an `exit` bind function.
Fixes#7604.
This is slated for removal in python 3.10, see
https://www.python.org/dev/peps/pep-0594/#cgi.
We currently only use it for three things:
- escape_html in old python versions that didn't have that in the html
module
- Parsing multipart/form-data
- Figuring out the charset for json
We keep the first one - if loading escape_html from html fails we fall
back to cgi.
We remove the second - I can't find any case where we use
multipart/form-data. Any place we post data we either explicitly pass
application/x-www-form-urlencoded or implicitly use application/json.
The third is the tricky bit. This drops charset detection under the
assumption that we're never going to encounter anything other than
utf-8 (or ascii, which is a utf-8 subset). I'm not sure that holds,
but if it doesn't we can just add a regex to parse the charset.
Prior to this change, `fish_private_mode` worked by just suppressing
history outright. With this change, `fish_private_mode` can be toggled on
and off. Commands entered while `fish_private_mode` is set are stored but
in memory only; they are not written to disk.
Fixes#7590Fixes#7589
Commands that start with a space should not be written to the history
file. Prior to this change, that was implemented by simply not adding them
to history. Items with leading spaces were simply dropped.
With this change, we add a 'history_persistence_mode_t' to
history_item_t, which tracks how the item persists. Items with leading
spaces are now marked as "ephemeral": they can be recovered via up arrow,
until the user runs another command, or types a space and hits return.
This matches zsh's HIST_IGNORE_SPACE feature.
Fixes#1383
These used a different object format, so they were passed to
interpret_color wrong.
Because the "common" and "syntax" division doesn't really help all
that much, let's just flatten the thing.
See #7596.
Don't go into implicit interactive mode without ever executing
anything - not even `exit` or reacting to ctrl-d. That just renders
the shell useless and unquittable.
It also reflows.
We might want to think about doing something more extensible here, as
konsole is also about to add reflow, but for now the main problem
children here are VTE and alacritty.
Extends #7491.
It was always a bit ridiculous that argparse required `X-longflag` if
that "X" short flag was never actually used anywhere.
Since the short letter is for getopt's benefit, we can hack around
this with our old friend: Unicode Private Use Areas.
We have a counter, starting at 0xE000 and going to 0xF8FF, that counts
up for all options that don't have a short flag and provides one. This
gives us up to 6400 long-only options.
6.4K should be enough for everybody.
