The tty device timestamps on MS Windows aren't usable because they're always
the current time. So fish can't use them to decide if the entire prompt needs
to be repainted.

Fixes#3110
We need to actually export the curses/terminfo env vars in order for
`setupterm()` to be able to use them. While fixing this I reworked the
fallback logic implemented by @zanchey in response to issue #1060 in
order to simplify the logic and clarify the error messages.
This does not allow someone to change the curses/terminfo env vars after
the first prompt is displayed (you can but it won't affect the current
fish process). It only makes it possible to set `TERM`, `TERMINFO`, and
`TERMINFO_DIRS` in *config.fish* or similar config file and have them be
honored by fish.
The issue here is that when inserting a common prefix for e.g. a
substring match, we increase the amount of available candidates again to
things the user didn't want.
An example is in share/functions - a completion for "inter" would
previously expand to "__fish_" because it matched:
- __fish_config_interactive.fish
- __fish_print_interfaces.fish
- __fish_print_lpr_printers.fish
The completion afterwards would then show 189 possible matches, only
three of which (the above) actually matched the original "inter".
Fixes#3089.
Cppcheck was complaining about the `return val.c_str()` at the end of the
`wgettext()` function. That would normally a bug since the lifetime of
`val` ends when the function returns. In this particular case that's not
true because the string is interned in a cache. Nonetheless, rather than
suppress the lint warning I decided to modify the API to be more idiomatic.
In the process of fixing the aforementioned lint warning I fixed several other
lint errors in that module.
This required making our copy of `wgetopt()` compatible with the rest of
the fish code. Specifically, by removing its local definitions of the
"_" macro so it uses the same macro used everywhere else in the fish
code. The sooner we kill the use of wide chars the better.
This only eliminates errors reported by `make lint`. It shouldn't cause any
functional changes.
This change does remove several functions that are unused. It also removes the
`desc_arr` variable which is both unused and out of date with reality.
This makes the wide char tests run by `./fish_tests` pass on systems where
sizeof wchar_t is two (e.g., Cygwin). In doing so it corrects several
problems with the underlying code in module *utf8.cpp* such as allowing
five and six byte UTF-8 sequences. They were allowed by the original
Unicode proposal but are not allowed by the adopted standard.
Configure the tty driver to ignore the lnext (\cV) and werase (\cW) characters
so they can be bound to fish functions.
Correct the `fish_key_bindings` program to initialize the tty in the same
manner as the `fish` program.
Fixes#3064
Overwriting the user's clipboard by default is annoying and contributors
don't use it.
This is better served via an explicit binding that calls e.g. `xsel`.
This change allows the user to specify the script name on the CLI in addition
to being redirected from stdin. It also adds a `-w` flag to write the modified
script to the original file.
I noticed that the `test_convert()` function was randomly failing when
run on OS X Snow Leopard. I tracked it down to the `mbrtowc()` function on
that OS being broken. Explicitly testing for UTF-8 prefixes that identify
a sequence longer than four bytes (which the Unicode standard made illegal
long ago) keeps us from having encoding errors on those OS's.
This also makes the errors reported by the `test_convert()` function actually
useful and readable.
Lastly, it makes it possible to build fish on OS X Snow Leopard.
Drops configure check for wcsdup, wcslen, wcscasecmp, wcsncasecmp,
wcwidth, wcswidth, wcstok, fputwc, fgetwc, and wcstol. Drop the fallback
implementations of these on non-Snow Leopard platforms.
Work on #2999.
fwprintf would segfault on DragonFly BSD 1.4.0, released in January
2006. This was fixed by DragonFly BSD 1.4.4, released in April 2006. It
seems unlikely that anyone is still running a ten-year-old, unsupported
version, and hoping that fish will continue to build.
I've checked this in virtual machines.
Work on #2999.
The autoconf-generated config.h contains a number of directives which
may alter the behaviour of system headers on certain platforms. Always
include it in every C++ file as the first include.
Closes#2993.
This change does several things. First, and most important, it allows
dumping the "n" most recent stack frames on each debug() call. Second,
it demangles the C++ symbols. Third, it prepends each debug() message
with the debug level.
Unrelated to the above I've replaced all `assert(!is_forked_child());`
statements with `ASSERT_IS_NOT_FORKED_CHILD()` for consistency.
Fix a minor bogosity I noticed while building fish on OS X Snow
Leopard. It's technically not a bug because only old compilers complain
about the original statement but this change makes the one line this
changes consistent with the rest of the fish code.
It's currently too easy for someone to bork their shell by doing something
like `function test; return 0; end`. That's obviously a silly, contrived,
example but the point is that novice users who learn about functions are
prone to do something like that without realizing it will bork the shell. Even
expert users who know about the `test` builtin might forget that, say, `pwd`
is a builtin.
This change adds a `--shadow-builtin` flag that must be specified to
indicate you know what you're doing.
Fixes#3000
I'm doing this as part of fixing issue #2980. The code for managing tty modes
and job control is a horrible mess. This is a very tiny step towards improving
the situation.
The original `key_reader` program was useful but didn't do much that `xxd`
or `od -tx1z` didn't do. Furthermore, it wasn't built and installed by
default. This change adds features that make it superior to those programs
for decoding interactive key presses and makes it a first-class citizen
like the `fish_indent` program that is always available.
Fixes#2991
The fork (create new process) related debugging messages rely on an
undocumented env var and use `printf()` rather than `debug()`. There are
also errors in how the fork count is tracked that this fixes.
Fixes#2995
Some `oclint` errors regarding "useless parentheses" are meaningfull. But
the vast majority are bogus in as much as removing the parentheses reduces
readability. So fix a few of the egregious uses and otherwise suppress
that error.
I missed restyling a few "switch" blocks to make them consistent with the rest
of the code base. This fixes that oversight. This should be the final step in
restyling the C++ code to have a consistent style. This also includes a few
trivial cleanups elsewhere.
I also missed restyling the "complete" module when working my way from a to z
so this final change includes restyling that module.
Total lint errors decreased 36%. Cppcheck errors went from 47 to 24. Oclint P2

For this change I decided to bundle the remaining modules that need to be

This also fixes a stupid mistake from an earlier commit where I didn't realize
that osx/config.h was meant to be included as a semi-static file in the
repository.
fish_title currently outputs some escaped text, which can confuse
the line driver (#2453). Issue a carriage return so the line driver
knows we are at the beginning of the line, unless we are writing
the title as part of the prompt. In that case, we may have text from
the previous command still on the line and we don't want to move the
cursor.
Fixes#2453
Don't `#include "*.cpp"` modules in other cpp modules. I already took care
of all the builtin_*.cpp modules in my previous change where I restyled
the builtin code. This change fixes the two remaining instances of this
anti-pattern.
Now that the IWYU cleanup has been merged compile all, not just a couple, of
the builtin modules independent of builtin.cpp. That is, no longer `#include
builtin_NAME.cpp` in builtin.cpp. This is more consistent, more in line with
what developers expect, and is likely to reduce mistakes.
Reduces lint errors from 384 to 336 (-13%). Line count from 6307 to 4988 (-21%).

Remove the "make iwyu" build target. Move the functionality into the
recently introduced lint.fish script. Fix a lot, but not all, of the

Fixes#2957
The OS X Xcode IDE has a weird requirement that block comments preceding a
function or class definition must begin with three slashes rather than two if
you want the comment displayed in the "Quick Help" window.
Make the history code conform to the new style guide. Every change was
produced by clang-format (e.g., `make style`) with the exception of
comments which were manually reformatted. That has to be done by hand
since clang-format leaves comments alone other than to reflow comment
lines to get them below the allowed line length.
The total number of lines is reduced by 313 lines (13%) in the two
affected files. Line count is generally a poor metric but in this
case it reflects an increase in information density without a loss in
readability. Furthermore, the standardization of braces, whitespace,
and comment style will make it easier for people to read the code.
This reduces the number of warnings by `make lint` from 168 to 87 (a 48%
decrease). Making it much easier to focus on the substantive lint issues.
Further improvements are possible. For example, many comments are not
very helpful (e.g., they point out the obvious) or provide insufficient
detail. But those are beyond the scope of this change.
This is the first step in resolving issue #2902.
The readlink() function does not null terminate the path it returns.
Remove the OS X code that deals with a path buffer that is too short. For
one thing a loop isn't needed since we're told how big of a buffer
is required if the first _NSGetExecutablePath() call fails. But more
important it is so unlikely that the path will be longer than PATH_MAX
that if it is we should just give up.
Fixes 2931.
I just noticed that depending on the state of your working tree there can be
one or more spaces after the modification token and the file name. If there is
more than one space that causes the `string split` to produce unexpected
output.
In keeping with the change made by @ridiculousfish earlier today modify
the `keyword_description()` function to return a const wchar_t pointer.
Also, simplify the `token_type_description()` function to use the recently
introduced mapping array. This changes the wording of many of the token
type descriptions. However, I can't see this as being a problem since
the original descriptions (e.g., "token_redirection") are no clearer to
someone not acquainted with the implementation.
Fish keywords can be quoted and split across lines. Prior to this change
`fish_indent` would retain such odd, obfuscated, formatting. This change
results in all keywords being converted to their canonical form.
This required fixing a bug: the keyword member of parse_node_t wasn't being
populated. This hadn't been noticed prior to now because it wasn't used.
Fixes#2921
This code represents only risk and does nothing useful for anything
that can compile fish.
In C++ situations where __STDC_VERSION__ is unset (as it should be),
fish was assuming we are on < C99 and setting it to __FUNCTION__.
Basically always, __PRETTY_FUNCTION__ ends up reaplaced by __FUNCTION__, this hurt
error message usefulness and richness.
__PRETTY_FUNCTION__: const thing::sub(int)
__FUNCTION__: sub
Prior to this fix, when completing a command that doesn't have a /, we
would prepend each component of PATH and then expand the whole thing. So
any special characters in the PATH would be interpreted when performing
tab completion.
With this fix, we pull the PATH resolution out of complete.cpp and
migrate it to expand.cpp. This unifies nicely with the CDPATH resolution
already in that file. This requires introducing a new expand flag
EXPAND_SPECIAL_FOR_COMMAND, which is analogous to EXPAND_SPECIAL_CD
(which is renamed to EXPAND_SPECIAL_FOR_CD). This flag tells expand to
resolve paths against PATH instead of the working directory.
Fixes#952
When determining the old path, get the existing value in any scope,
not just the set scope. Also only complain about absolute paths:
relative paths are expected to be invalid sometimes.
Modify `fish_indent` to emit redirections without a space before the target of
the redirection; e.g., "2>&1" rather than "2>& 1" as the former is clearer to
humans.
Fixes#2899
Per discussion in pull-request #2891, it's not available on Linux (we just
fill it with zero), and unless run as root on OS X (or other BSD system) it
will be zero. Remove it from file_id_t. Also fix the initialization of the
file_id_t structure.
Fixes#2891
This is a quick and dirty conversion of the atypical, and undocumented,
logging done by env_universal_common.cpp to the usual `debug()` pattern. I
didn't want to drop the messages because they could be useful when
debugging future issues. So I simply converted them to the lowest debug
level using the normal debug() function.
Fixes#2887
Cppcheck has identified a lot of unused functions. This removes funcs that
are unlikely to ever be used. Others that might be useful for debugging I've
commented out with "#if 0".
This fixes all memory leaks found by compiling with
clang++ -g -fsanitize=address and running the tests.
Method:
Ensure that memory is freed by the destructor of its respective container,
either by storing objects directly instead of by pointer, or implementing
the required destructor.
When explicitly asking for the fish version string the information
should go to stdout rather than stderr. Also, there is no reason to use
exit_without_destructors() rather than exit() in that code path. We
actually want the side-effects of exit() such as flushing stdout and
there aren't any threads or other things that could cause a normal exit
to fail when that function is run.
The early return skipped all cleanup.
This problem is a case for the classic "goto fail" paradigm, but this
change instead makes a few adjustments to take advantage of a previously
unused level of indentation to conditionally execute the success path.
The error message now prints the filename instead of "open",
which should be more idiomatic.
Tip:
This patch makes sense if viewed with `git show --ignore-space-change`.
The swap-selection-start-stop function goes to the other end of the highlighted text, the equivalent of `o' for vim visual mode.
Add binding to the swap-selection-start-stop function, `o' when in visual
mode.
Document swap-selection-start-stop, begin-selection, end-selection, kill-selection.
The relevant standards allow the mbtowc/mbrtowc functions to reject
non-ASCII characters (i.e., chars with the high bit set) when the locale
is C or POSIX. The BSD libraries (e.g., on OS X) don't do this but
the GNU libraries (e.g., on Linux) do. Like most programs we need the
C/POSIX locales to allow arbitrary bytes. So explicitly check if we're
in a single-byte locale (which would also include ISO-8859 variants)
and simply pass-thru the chars without encoding or decoding.
Fixes#2802.
The u_int typedef fails to compile on all platforms (e.g. Windows). It
is part of the code imported from tmux.
Update it to the SUS-standard uid_t.

Address the feedback from the prior commit:
- Change the sense of return value testing to match more common
comparison idiom
- Test result of fchmod as well as fchown
- Change sense of return value testing around wrename as well
- Include errno where possible in error message
The function fchown is annotated with warn_unused_result. As
formerly used in the code, it would emit a compiler warning
```warning: ignoring return value of ‘fchown’, declared with
attribute warn_unused_result [-Wunused-result]```
This commit notes the return value and emits appropriate error/logging
messages if the call fails, creating more traceable results and
satisfying the compiler.
There is no longer a good reason to detect whether or not getopt_long()
is available. All UNIX implementations we're likely to run on have it. And
if we ever find one that doesn't the right thing to do is not fallback to
getopt() but to include the getopt_long() source in our package like we
do with the pcre2 library. Since it's licensed under LGPL we can legally
do so if it becomes necessary.
This partially addresses issue #2790.
Previously, when decoding UTF-8, we would first run through the
array to compute the correct size, then allocate a buffer of that size,
then run through the array again to fill the buffer, and then copy it
into a std::wstring. With this fix we can copy it into the string
directly, reducing allocations and only requiring a single pass.
This narrows the range of Unicode codepoints fish reserves for its own
use from U+E000 thru U+F8FE (6399 codepoints) to U+F600 thru U+F73F (320
codepoints). This is still not ideal since fish shouldn't be using any
Unicode private-use codepoints but it's a step in the right direction.
This partially addresses issue #2684.
This was used to cache a narrow string representation
of commands, so that if certain system calls returned errors
after fork, we could output error messages without allocating
memory. But in practice these errors are very uncommon, as are
commands that have wide characters. It is simpler to do a best-effort
output of the wide string, instead of caching a narrow string
unconditionally.
Prior to this fix, read_ni would use parse_util_detect_errors
to lint the script to run, and then parser_t::eval() to execute it.
Both functions would parse the script into a parse tree. This allows
us to re-use the parse tree, improving perfomance.
Introduces a new template moved_ref which is like an rvalue reference.
This allows passing around objects while being explicit that the
receiver may acquire ownership. This will help reduce some allocations.
pcre2_substitute() now sets the output buffer length to PCRE2_UNSET (~0)
if the output buffer is determined to be too small. This change keeps
track of the buffer size separately where pcre2 can't touch it.
A better fix would be to let pcre2 tell fish what size buffer it needs.
This can be done with PCRE2_SUBSTITUTE_OVERFLOW_LENGTH, but this
requires pcre2 10.21 or later (released January 12), which may be too
new to introduce as a dependency at this point.
Fixes#2743
Expand globs to zero arguments (nullglob) only for set, for and count.
The warning about failing globs, and setting the accompanying $status,
now happens regardless of mode, interactive or not.
It is assumed that the above commands are the common cases where
nullglob behaviour is desirable.
More importantly, doing this with `set` is a real feature enabler,
since the resulting empty array can be passed on to any command.
The previous behaviour was actually all nullglob (since commit
cab115c8b9), but this was undocumented;
the failglob warning was still printed in interactive mode,
and the documentation was bragging about failglob behaviour.
The argv argument may be modified on calls to exchange within the function and should not be const qualified (it's not true from the caller's point of view).
On arm, wchar_t is unsigned, and C++11 and newer disallow implicit
narrowing conversions inside braces. Use an explicit conversion to
fix the build on GCC 6 and up, which defaults to C++11.
This changes the default escape timeout for the default keybindings (emacs
mode) to 300ms and the default for vi keybindings to 10ms.
I couldn't resist fixing a few nits in the fish_vi_key_bindings.fish file
since I was touching it to set the escape timeout.
All versions of fish prior to this change silently discarded anything written
to stderr while source a config.fish file. Apparently just to avoid having
the source command display an error if the file did not exist. This can mask
real problems. So instead this change explicitly checks whether the file is
readable and silently skips sourcing it if it isn't.
Resolves issue #2702.
Introduce a "fish_escape_delay_ms" variable to allow the user to configure the
delay used when seeing a bare escape before assuming no other characters will
be received that might match a bound character sequence. This is primarily
useful for vi mode so that a bare escape character (i.e., keystroke) can
switch to vi "insert" to "normal" mode in a timely fashion.
Rather than storing short and long options separately, using
a complicated set of invariants, store them in a single string
and use an explicit type complete_option_type_t to track how they
are interpreted.
This was a "cache" of dubious value that was also very confusing.
The idea was to express in one place all of the short options that
were allowed for a command, in a big string. But it's simpler to
just construct that on-demand by walking the list of
complete_entry_opt_t.
Also remove some other dead code as part of cleanup.
The fix for #2075 inadvertently started unescaping the strings emitted
from `commandline -b`. Only strings emitted with the `-o` flag are
supposed to be unescaped.
Fixes#2210.
If you have a prompt preceded by a new line, you'll get a line full of spaces instead of an empty line above your prompt. This doesn't make a difference in normal usage, but copying and pasting your terminal log becomes a pain. This commit clears that line, making it an actual empty line.
The random builtin command may or may not produce values with a truly
random distribution. So make the documentation reflect that reality. Also,
make the command consistent with similar shells (e.g., bash, zsh) which
produce a range of [0..32767].
Resolves issue #1272.
Before this change, `fish ./test.fish` would fully resolve the
relative paths and symlinks of test.fish, as reported by `status -f`.
However `source` would not. With this change, both cases return relative
paths. `realpath` may be used by scripts to resolve them.
Fixes#2643
My PR #2578 had the unexpected side-effect of altering the tty modes of
commands run via "fish -c command" or "fish scriptname". This change fixes
that; albeit incompletely. The correct solution is to unconditionally set
shell tty modes if stdin is attached to a tty and restore the appropriate
modes whenever an external command is run -- regardless of the path used to
run the external command. The proper fix should be done as part of addressing
issues #2315 and #1041.
Resolves issue #2619
Increase the delay between seeing an escape character and giving up on
whether additional characters that match a key binding are seen. I'm
setting the value to 500 ms to match the readline library. We don't need
such a large window for sequences transmitted by a terminal (even over ssh
where network delays can be a problem). However, we can't expect humans to
reliably press the escape key followed by another key with an inter-char
delay of less than ~250 ms based on my testing and research. A value of
500 ms provides a nice experience even for people using "fish_vi_mode"
bindings as a half second to switch from insert to normal mode is still
fast enough that most people won't even notice.
Resolves#1356
While investigating issue #2619 my first thought was that the problem
had something to do with the "is_interactive_session" global variable.
That preliminary conclusion appears to be wrong (i.e., the problem
lies elsewhere). However, that hypothesis caused me to look at function
"fish_parse_opt" and other mentions of "is_interactive_session".
I decided to take the opportunity to simplify and improve the style of
"fish_parse_opt" since I just spent an hour reviewing the code that
references "is_interactive_session". For example, the "has_cmd" variable
isn't really needed. And there is inconsistent whitespace not to mention
confusion about bool's versus int's and zero versus NULL.
Rather than returning a list of productions and an index,
return the relevant production directly from the rule function.
Also introduce a tag value (replacing production_idx) which tracks
information like command decorations, etc. with more clarity.
When replacing the existing fish process with a new process it is
important to restore the temrinal modes to what they were when fish
started running. We don't want any tweaks done for the benefit of fish
(e.g., disabling ICRNL mode) to bleed thru to an "exec"ed command.
Resolves#2609
If stdio is dead due to EPIPE, there's no great reason to spew a stack dump.
This will still write an error to stderr if stdout dies. This might be
undesirable, but changing that should be considered separately.
It is critical that we ensure our interactive tty modes are in effect at
the earliest possible moment. This achieves that goal and is harmless if
stdin is not tied to a tty. The reason for doing this is to ensure that
\r characters are not converted to \n if we're running on the slave side
of a pty controlled by a program like tmux that is stuffing keystrokes
into the pty before we issue our first prompt.
The special token "normal" should not be in the basic sixteen color table
because a) it is not a color, and b) it is special cased with the result of
resetting the terminal colors (usually via a ANSI X3.64 CSI [0m sequence).
This adds support for the ANSI x3.64 "bright" colors in the basic sixteen
color palette. This is especially useful when trying to use the base colors
as a background color. The "bright" variants tend to be more useful as
background colors compared to the non-bright variants.
This also fixes a bug in so far as palette number 7 is actually grey and
not white whereas palette number 15 is white. At least on the terminal
emulators on which I've tested this change (Ubuntu xterm & uxterm, Mac
OS X Terminal & iTerm2).
Resolves issue #1464.
We identify when the universal variable file has changed out from under us by
comparing a bunch of fields from its stat: inode, device, size, high-precision
timestamp, generation. Linux aggressively reuses inodes, and the size may be
the same by coincidence (which is the case in the tests). Also, Linux
officially has nanosecond precision, but in practice it seems to only uses
millisecond precision for storing mtimes. Thus if there are three or more
updates within a millisecond, every field we check may be the same, and we are
vulnerable to the ABA problem. I believe this explains the occasional test
failures.
The solution is to manually set the nanosecond field of the mtime timestamp to
something unlikely to be duplicated, like a random number, or better yet, the
current time (with nanosecond precision). This is more in the spirit of the
timestamp, and it means we're around a million times less likely to collide.
This seems to fix the tests.
input_mapping_execute, when passed false for allow_commands, will return
R_NULL. However currently it does this unconditionally, even if we don't
have any commands. This defeats our read-ahead optimization, so we
always read and process one byte at a time. This caused pasting to be
much slower.
Fixes#2215
If we are cd'ing into a directory, and the directory has only one

Previously 'set -ql' would only look for variables in the
immediate local scope. This was not very useful. It's also
arguably surprising, since a 'set -l' in a function, followed
by a 'set -ql' in a child block, would fail. There was also no
way to check for a function-scoped variable, since omitting the
scope would also pull in global variables.
We could revisit this and introduce an explicit function scope.
Fixes#2502
New implementation of migration code within the history_t class will
copy the contents of the old fish_history found in the config directory
to its new location in the data directory. The old file is left intact.
This is done only in the event that a fish_history is not already found in
the data directory ($XDG_DATA_HOME/fish or ~/.local/share/fish).
The fish_history file is now located in the "data"
directory ($XDG_DATA_HOME/fish or ~/.local/share/fish),
accessible using the function `path_get_data`.
(This commit also cleans trailing whitespace in the source file.)
Add new functions path_get_data and path_create_data which parallel existing
functions path_get_config and path_create_data. The new functions refer to
XDG_DATA_HOME, if it is defined, or ./local/share if not.
Modify history_filename to use the new function path_get_data.
As a consequence, fish_history will now be located in XDG_DATA_HOME,
not XDG_CONFIG_HOME.
Note that these changes mirror what is already used in
fish-shell/share/tools/create_manpage_completions.py, which stores the
completions in XDG_DATA_HOME
This change matches recommendations in the xdg basedir spec at
http://standards.freedesktop.org/basedir-spec/basedir-spec-0.7.html
($XDG_DATA_HOME defines the base directory relative to which user specific data
files should be stored. If $XDG_DATA_HOME is either not set or empty, a default
equal to $HOME/.local/share should be used.)
It addresses suggestions from the following issues:
1. Don't put history in $XDG_CONFIG_HOME (closes#744)
https://github.com/fish-shell/fish-shell/issues/744
2. Fish is placing non-config files in $XDG_CONFIG_HOME #1257https://github.com/fish-shell/fish-shell/issues/1257
3. Move non-config data out of $XDG_CONFIG_HOME #1669https://github.com/fish-shell/fish-shell/issues/1669
Teach Xcode to run new script xcode_version_gen.sh before building
the fish_shell and fish_indent targets. The script generates file
fish-build-version.h for inclusion by fish_version.cpp.
Note that Xcode always runs the script because of the phony target
named force-fish-build-version.h, but fish-build-version.h is only
touched if the contents of FISH-BUILD-VERSION-FILE change.
Fixes#890
This change eliminates global variables like stdout_buffer. Instead we wrap up
the IO information into a new struct io_streams_t, and thread that through
every builtin. This makes the intent clearer, gives us a place to hang new IO
data, and eliminates the ugly global state management like builtin_push_io.
This adds the new builtin 'string' which supports various string
manipulation and matching algorithms, including PCRE based regular
expressions.
Fixes#2296

- make match/replace without -a operate on the first match on each
argument
- use different exit codes for "no operation performed" and errors, as
grep does
- refactor regex compile code

Previously, the process's inherited $TERM value would be used.
This prevented users from being able to set $TERM in their config.fish files.
To make matters worse, the error message would print the computed $TERM value,
giving the mistaken impression that it was being used.

Cygwin FIFOs do not support more than one reader, so avoid them on this
platform. An autoconf feature test would be helpful but is tricky to
write.
Closes#2152.
When an error occurs midway through a token, like abc(def,
make the caret point at the location of the error (i.e. the paren)
instead of at the beginning of the token.
In a few places, we need to add a prefix to completions that
replace the token. This change factors that logic into its
own function prepend_token_prefix.
Rather than trying to detect Unicode support from the environment, check
the printable width of characters in the current locale before deciding
on whether to use them.
Closes#1927.
