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]
Prior to this change, a glob like `**/file.txt` would only match
`file.txt` in subdirectories; the `**` must match at least one directory.
This is historical behavior.
With this change we move a little closer to bash's implementation by
allowing a literal `**` segment to match in the current directory. That
is, `**/foo` will match both `foo` and `bar/foo`, while `b**/foo` will
only match `bar/foo`.
Fixes#7222.
