f843eb3d31 Add a template to parse integers easily/correctly (#3405)
* Adds a template to parse integers easily.

It's not enough to use intmax_t and check for empty strings: there are
limits. Adds a template to make it easy to parse an integer of any type.

Adds a compiler flag to flag existing dangers.

* nix warning, include <limits>, fix namespace error.

on MacOS `xcodebuild -quiet` will flag these intmax_t -> * conversions,
just use that if you want to find them.

e9b5505169 add a flag to limit history search results
This adds a flag to the `history search` command to limit the number of
matching entries to the first "n". The default is unlimited. This is
mostly useful in conjunction with aliases (i.e., functions) that are
intended to report the "n" most recent matching history entries without
piping the result through the user's pager.

Fixes #3244

204e79105a allow customizing history --show-time format
It would make fish more friendly if we allowed the user to specify the

76c73aa8ce alter history sub-command handling
This deprecates the use of long options for history sub-commands (e.g.,
`history --delete`) in favor of proper sub-commands (e.g., `history
delete`). It also eliminates the short options for those sub-commands.

Also change option processing to allow options anywhere on the command
line to match how the vast majority of fish builtins handle flags.

Replace --with-time with --show-time.

6faa2f9866 Tighten up empty string checks.
Fixes various spots throughout fish where broken strtoi checks
were converting empty strings to zero. Zero is not a valid pid and
this was causing breakage as well when input.

Nix fish_wcstoi - wcstoimax does the same thing.
Improve comments and some general cleanup.

cfefaaf4ee revert the --shadow-builtin flag
Implementing the --shadow-builtin flag has proven to be highly controversial.
Revert the introduction of that flag to the `function` command. If someone
shoots themselves in the foot by redefining a builtin as a function that's
their problem and not our responsibility to protect them from doing so.

710addde16 fix history --delete regression
The recent change to reconcile the history builtin command and function
broke an undocumented behavior of `history --delete`. This change
reinstates that behavior. It also adds an explicit `--exact` search mode
for the `--search` and `--delete` subcommands.

Fixes #3270

ee26eafc25 Ensure we continue to cover enums in switches

b53f42970c correct handling of history args
This fixes several problems with how the builtin `history` command handles
arguments. It now complains and refuses to do anything if the user specifies
incompatible actions (e.g., `--search` and `--clear`). It also fixes a
regression introduced by previous changes with regard to invocations that
don't explicitly specify `--search` or a search term.

Enhances the history man page to clarify the behavior of various options.

This change is already far larger than I like so unit tests will be added
in a separate commit.

Fixes #3224.

Note: This fixes only a couple problems with the interactive `history
--delete` command in the `history` function. The main problem will be
dealt with via issue #31.

09291735e6 Use locales preferred date format, fix up options
We don't seem to mention in the documentation that we were forcing
-t for all interactive uses. If we want to do that we should apply
that in the builtin.

history.fish reimplementing every option and doing things kind of
differently is a real pain and it's not clear if the docs are
referring to the or the wrapper script or both.

51468b7646 add function --shadow-builtin flag
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.

fc44cffac5 restyle switch blocks to match project style
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
errors went from 819 to 778. Oclint P3 errors went from 3252 to 1842.

df10b53c0c restyle builtin modules to match project style
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%).

Another step in resolving issue #2902.

c2f1df1d4a fix handling of non-ASCII chars in C locale
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.

c1bd3b5824 Eliminate global variables associated with builtin IO
This change eliminates global variables like stdout_buffer. Instead we wrap up

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.
