Originally I sought out to configure the foreground color of the
selected text in the pager. After reading a thread on a github issue I
was inpired to do more: now you can conifgure any part of the pager when
selected, and when a row is secondary. More specifically this commit adds the
ability to specify a pager row's:
- Prefix
- Completion text
- Description
- Background
when said row is selected or secondary.
Currently, there are two possibilities for holes in the background:
- When there are two candidates with the same meaning (a long and a
short option or two candidates with the same description)
- When a candidate does not have a description (meaning the color
won't continue after it)
This changes both so the background just goes on.
In addition, it avoids making the background multiple times.
Fixes#4866.
A completion may have zero length; in this case the length of the
prefix was omitted and the completion was not visible. Correct the
calculation to account for zero-width completions.
Fixes#4424
Since we are including XXHash32/64 anyway for the wchar_t* hashing,
we might as well use it.
Use arch-specific hash size and xxhash for all wcstring hashing
Instead of using XXHash64 for all platforms, use the 32-bit version
when running on 32-bit platforms where XXHash64 is significantly slower
than XXHash32 (and the additional precision will not be used).
Additionally, manually specify wcstring_hash as hashing method for
non-const wcstring unordered_set/map instances (the const varieties
don't have an in-library hash and so already use our xxhash-based
specialization when calling std::hash<const wcstring>).
Completion strings, especially the description, might contain characters,
such as backspace, which make it impossible to calculate the width of
the string.
Fixes#4179
The primary pupose of this change is to make OpenSUSE builds happy by
adding a `DIE()` call so its build toolchain knows we won't fall off the
end of function `selection_direction_is_cardinal()`.
I recently upgraded the software on my macOS server and was dismayed to
see that cppcheck reported a huge number of format string errors due to
mismatches between the format string and its arguments from calls to
`assert()`. It turns out they are due to the macOS header using `%lu`
for the line number which is obviously wrong since it is using the C
preprocessor `__LINE__` symbol which evaluates to a signed int.
I also noticed that the macOS implementation writes to stdout, rather
than stderr. It also uses `printf()` which can be a problem on some
platforms if the stream is already in wide mode which is the normal case
for fish.
So implement our own `assert()` implementation. This also eliminates
double-negative warnings that we get from some of our calls to
`assert()` on some platforms by oclint.
Also reimplement the `DIE()` macro in terms of our internal
implementation.
Rewrite `assert(0 && msg)` statements to `DIE(msg)` for clarity and to
eliminate oclint warnings about constant expressions.
Fixes#3276, albeit not in the fashion I originally envisioned.
min_width dates back to the original full-screen pager.
After some careful inspection, the code path that uses min_width
is never executed and so the min_width machinery is useless.
Let's remove it!
This fixes some of the IWYU and cppcheck lint warnings. And only on
macOS (formerly OS X). Fixing these types of warnings on a broader set
of platforms should be done but this is a baby step to making `make
lint-all` have few, if any, warnings. This reduces the number of lines
in the `make lint-all` output on macOS by over 500 lines.
My earlier attempt with commit 851e449 to eliminate all the compiler
warnings about mixing signed and unsigned ints in an expression
introduced a subtle bug. This fixes that mistake.
Fixes#3488
Adds a color reset thing, to ensure fish tries to use hard colors during
testing.
Also, work on a discrepancy (not introduced by my changes, afaik) when
with some combinations of color settings, and usage of --bold, caused super
flakey color paninting in the pager. Downwards movements that trigger
scrolling vs. upwards movement in the pager would only apply bold to
selections when moving upwards. The bold state of the command completions in
the pager was flipping flops on and off, depending on if there is a description
on the preceding line.
Implement a lame fix by reseting the color to normal and applying a
different style on the rightmost ')' which seems to be what was influencing it.
Makes fish use terminfo for coloring the newline glich char.
Where we already manage to cover an enum entirely in a switch
statement such that default: cannot be reached, help ensure
it stays that way by condemning that route.
Also adjust a 'const' I came across that is ignored.
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.
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.
Resolves#2902.
Remove the "make iwyu" build target. Move the functionality into the
recently introduced lint.fish script. Fix a lot, but not all, of the
include-what-you-use errors. Specifically, it fixes all of the IWYU errors
on my OS X server but only removes some of them on my Ubuntu 14.04 server.
Fixes#2957
This change moves source files into a src/ directory,
and puts object files into an obj/ directory. The Makefile
and xcode project are updated accordingly.
Fixes#1866
