2022-03-25introduce drw_fontset_getwidth_clamp()NRK
getting the width of a string is an O(n) operation, and in many cases users only care about getting the width upto a certain number. instead of calling drw_fontset_getwidth() and *then* clamping the result, this patch introduces drw_fontset_getwidth_clamp() function, similar to strnlen(), which will stop once we reach n. the `invert` parameter was overloaded internally to preserve the API, however library users should be calling drw_fontset_getwidth_clamp() and not depend upon internal behavior of drw_text().
2022-03-25drw_text: improve both performance and correctnessNRK
this patch makes some non-trivial changes, which significantly improves the performance of drawing large strings as well as fixes any issues regarding the printing of the ellipsis when string gets truncated. * performance: before there were two O(n) loops, one which finds how long we can go without changing font, and the second loop would (incorrectly) truncate the string if it's too big. this patch merges the overflow calculation into the first loop and exits out when overflow is detected. when dumping lots of emojies into dmenu, i see some noticeable startup time improvement: before -> after 460ms -> 360ms input latency when scrolling up/down is also noticeably better and can be tested with the following: for _ in $(seq 20); do cat /dev/urandom | base64 | tr -d '\n' | head -c 1000000 echo done | ./dmenu -l 10 * correctness: the previous version would incorrectly assumed single byte chars and would overwrite them with '.' , this caused a whole bunch of obvious problems, including the ellipsis not getting rendered if then font changed. in addition to exiting out when we detect overflow, this patch also keeps track of the last x-position where the ellipsis would fit. if we detect overflow, we simply make a recursing call to drw_text() at the ellipsis_x position and overwrite what was there. so now the ellipsis will always be printed properly, regardless of weather the font changes or if the string is single byte char or not. the idea of rendering the ellipsis on top incase of overflow was from Bakkeby <bakkeby@gmail.com>, thanks! however the original patch had some issues incorrectly truncating the prompt (-p flag) and cutting off emojies. those have been fixed in here.

2021-08-20Revert "Improve speed of drw_text when provided with large strings"Hiltjo Posthuma
This reverts commit c585e8e498ec6f9c423ab8ea07cf853ee5b05fbe. It causes issues with truncation of characters when the text does not fit and so on. The patch should be reworked and properly tested.
2021-08-09add support for more keypad keysHiltjo Posthuma
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. This adds a few lines but no complexity.
2021-08-09Improve speed of drw_text when provided with large stringsMiles Alan
Calculates len & ew in drw_font_getexts loop by incrementing instead of decrementing; as such avoids proportional increase in time spent in loop based on provided strings size.

2019-03-03revert IME supportHiltjo Posthuma
dmenu will not handle IME support (st will, atleast for now). revert parts of commit 377bd37e212b1ec4c03a481245603c6560d0be22 this commit also broke input focus.

2019-01-27dmenu.1: document improved fastgrab behaviour from previous patchHiltjo Posthuma
2019-01-27Use slow path if stdin is a ttydok
If stdin is a tty and dmenu is ran with the fast option then it's impossible to close stdin because the keyboard is already grabbed.

2018-06-02Makefile: just show the compiler outputHiltjo Posthuma
Don't be fancy and just show the actual output so debugging is simpler.

Building with debug symbols is worthless unless LDFLAGS are manually adjusted as well.

2016-12-11Revert "fix input text matching"Andrew Gregory
This reverts commit 09d0a36e0370f7ca9bdb171bf93c5ac3131c5a92. 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.
