NRK 528d39b011 tab-complete: figure out the size before copying
we already need to know the string length since `cursor` needs to be
adjusted.

so just calculate the length beforehand and use `memcpy` to copy exactly
as much as needed (as opposed to `strncpy` which always writes `n`
bytes).

NRK 32db2b1251 readstdin: use getline(3)
currently readstdin():
   - fgets() into a local buffer,
   - strchr() the buffer to eleminate the newline
   - stdups() the buffer into items

a simpler way is to just use getline(3), which will do the allocation
for us; eliminating the need for stdup()-ing.

additionally getline returns back the amount of bytes read, which
eliminates the need for strchr()-ing to find the newline.

Hiltjo Posthuma e1e1de7b3b inputw: improve correctness and startup performance, by NRK
Always use ~30% of the monitor width for the input in horizontal mode.

Patch adapted from NRK patches.
This also does not calculate inputw when using vertical mode anymore (because
the code is removed).

Hiltjo Posthuma 31fa07b984 Revert "avoid redraw when there's no change"
This reverts commit 6818e07291.

This broke keys such as ^W to delete-backward-word

NRK 6818e07291 avoid redraw when there's no change
while i was timing the performance issue, i noticed that there was lots
of random redrawing going on.

turns out there were coming from here; if someone presses CTRL/ALT etc
without pressing anything else, nothing will be inserted, so nothing
will change. but the code will `break`, go down and do a needless redraw.

this patch changes it to simply return if the keypress iscntrl()

also avoid potential UB by casting *buf into an unsigned char.

NRK b43ec0577f free all allocated items, use %zu for size_t
`items` itself is not checked for NULL as calling free on NULL is defined to be
a no-op.

NRK 77526f756e inputw: improve correctness and startup performance
a massive amount of time inside readstdin() is spent trying to get the
max input width and then put it into inputw, only for it to get clamped
down to mw/3 inside setup().

it makes more sense to calculate inputw inside setup() once we have mw
available. similar to the last patch, i see noticeable startup
performance improvement:

before -> after
160ms  -> 60ms

additionally this will take fallback fonts into account compared to the
previous version, so it's not only more performant but also more correct.
2022-03-25 22:49:07 +01:00
NRK 7269c5355d significantly improve performance on large strings
this replaces inefficient pattern of `MIN(TEXTW(..), n)` with
drw_fontset_getwidth_clamp() instead, which is far more efficient when
we only want up to a certain width.

dumping a decently sized (unicode) emoji file into dmenu, I see the
startup time drop significantly with this patch.

before -> after
360ms  -> 160ms

this should also noticeably improve input latency (responsiveness) given
that calcoffsets() and drawmenu() are pretty hot functions.

Hiltjo Posthuma cd2133a5f6 add support for more keypad keys
The keypad Enter key was already supported. On some keyboard layouts like my
laptop the page-up and page-down key is more comfortable to use.

Andrew Gregory 5cd66e2c6c Revert "fix input text matching"
This reverts commit 09d0a36e03.

Using strncmp with the length of the user input turns it into a prefix
match rather than an exact match as it's supposed to be.

Quentin Rameau a4053bc4e4 Print highlighted input text only on single match
When the input text fully matches a single item, do not draw the item
and highlight the input text to show that it matches an item in
opposition to regular input text not matching anything.

S. Gilles 76eb578304 fix: Do not crash on e.g. dmenu < /dev/null 2016-06-28 17:51:28 +02:00
Markus Teich 44c7de3dcf import new drw from libsl and minor fixes.
- extract drawitem function (code deduplication)
- fix bug where inputw was not correctly calculated from the widest item, but
  just from the one with the longest strlen() which is not the same. It's better
  now, but does not account for fallback fonts, since it would be too slow to
  calculate all the correct item widths on startup.
- minor code style fixes (indentation, useless line breaks)

Hiltjo Posthuma da0b9eb6c9 fix: multimon: always spawn client on first monitor if specified with -m 0
This was always broken.

Reproduce:
	focus client on second monitor, spawn dmenu with -m 0.

Result:
	Old wrong behaviour: dmenu spawns on second monitor (focused client).
	Now: dmenu spawns on specified monitor (first).

Hiltjo Posthuma 240a7810e4 fix paste from clipboard (ctrl+shift+y)
from Joshua Lloret on the ML:

"attached is a small patch to enable pasting from clipboard, as well as primary.

It seems like there was already code in there to allow this, but since there was never any case to match the upper case 'Y', that inline if would always evaluate to false."
