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.
One warns about using system() which we only use in test code (we're all adults):
src/fish_tests.cpp:2015:9: warning: calling 'system' uses a command processor [cert-env33-c]
if (system("mkdir -p test/fish_expand_test/bb/")) err(L"mkdir failed");
Some conversion warnings that don't seem very useful:
src/input_common.cpp:181:20: warning: 'signed char' to 'wint_t' (aka 'unsigned int') conversion; consider casting to 'unsigned char' first. [cert-str34-c]
wint_t b = evt.get_char();
Warning about varargs doesn't make sense, because some of our functions use std::vswprintf() internally.
src/ast.cpp:486:10: warning: do not define a C-style variadic function; consider using a function parameter pack or currying instead [cert-dcl50-cpp]
void internal_error(const char *func, const wchar_t *fmt, ...) const {
Finally, what seems like a false positive; "va" is initialized by va_copy:
src/common.cpp:468:18: warning: Function 'vswprintf' is called with an uninitialized va_list argument [clang-analyzer-valist.Uninitialized]
status = std::vswprintf(buff, size / sizeof(wchar_t), format, va);
A mildly interesting one is the call to test_wchar2utf8 with a non-null
pointer ("u1"/"dst") but 0 length. In this case we relied on malloc(0)
returning non-null which is not guaranteed.
src/fish_tests.cpp:1619:23: warning: Call to 'malloc' has an allocation
size of 0 bytes [clang-analyzer-optin.portability.UnixAPI]
mem = (char *)malloc(dlen);
^
test_wchar2utf8(w1, sizeof(w1) / sizeof(*w1), u1, 0, 0, 0,
"invalid params, dst is not NULL");
lint.fish receives arguments that contain multiple includes and defines.
As a result, we passed arguments like
"-I/usr/include -I$HOME/fish-shell/build -I/usr/include"
to cppcheck which interprets this as a single include directory.
This leads to errors like this one (because the "build" dir was missing):
src/common.h:4:0: information: Include file: "config.h" not found. [missingInclude]
