| ubitux | hi | 14:38.52 |
| mubot | Welcome to #mupdf, the channel for MuPDF. If you have a question, please ask it, don't ask to ask it. Do be prepared to wait for a reply as devs will check the logs and reply when they come on line. | 14:38.52 |
| ubitux | pressing "space" to jump to the next page seems to work, but never for the last for some reason | 14:39.21 |
| | typically with a beamer presentation | 14:39.28 |
| | my workaround is to use the "down" key | 14:39.36 |
| | i'm not sure why | 14:39.42 |
| | is this on purpose? | 14:39.44 |
| | http://b.pkh.me/p/2020-03-18-154341-Phaet2vu | 14:43.52 |
| | can be reproduced like this | 14:43.56 |
| | (the press space as much as you want, it will never reach the last one) | 14:45.09 |
| ator | ubitux: I've never seen that particular behavior. | 14:45.20 |
| | ubitux: but I have vague recollections about a bug report saying that, but years ago | 14:45.39 |
| | ubitux: which version are you using? | 14:46.07 |
| ubitux | i'm using 1.16.1, and i don't think it's a regression because i already expected a few months back | 14:46.09 |
| | expected *it* | 14:46.25 |
| | can you reproduce? do you want the pdf? | 14:46.36 |
| ator | ubitux: can you reproduce with the current master? | 14:47.40 |
| ubitux | i guess i can try… | 14:47.57 |
| ator | it might be related to commit 606fcf8383943d7f986d6706f1cb67fbdab0e224 | 14:48.25 |
| | https://bugs.ghostscript.com/show_bug.cgi?id=701402 | 14:49.03 |
| ubitux | (ah the backspace thing, yes please restore it!) | 14:50.18 |
| | mmh i don't have lcms2mt.h, only lcms2.h | 14:51.05 |
| ator | build with our third party libraries (do a recursive clone) | 14:51.23 |
| | or set USE_SYSTEM_LCMS2=yes for the makefile | 14:52.06 |
| | mupdf-gl does not have the smart-scrolling bug in 1.16.1, that's only mupdf-x11 (which gets a lot less testing since sebras is the only developer who uses it) | 14:55.04 |
| ubitux | USE_SYSTEM_LCMS2=yes USE_SYSTEM_FREETYPE=yes USE_SYSTEM_LIBJPEG=yes USE_SYSTEM_OPENJPEG=yes USE_SYSTEM_HARFBUZZ=yes | 14:55.24 |
| | seems i need all of this, bvut still failing | 14:55.31 |
| | make: *** No rule to make target 'build/release/thirdparty/mujs/one.o', needed by 'build/release/libmupdf-third.a'. | 14:55.40 |
| ator | you still need to clone recursively (or do "git submodule update --init" | 14:55.57 |
| | since not all of our dependencies are packaged as system libraries | 14:56.22 |
| | USE_SYSTEM_LIBS=yes is shorthand for setting all the ones you listed (see the top of Makethird) | 14:56.49 |
| ubitux | sorry, back | 15:11.58 |
| | mmh | 15:12.01 |
| | zsh: segmentation fault (core dumped) ./build/release/mupdf-x11 | 15:12.08 |
| | need to rebuild with debug | 15:12.54 |
| ator | don't forget to do a clean build if you change the USE_SYSTEM_xxx flags | 15:13.01 |
| ubitux | yeah i used git clean | 15:13.31 |
| | meh, it works now, well cool | 15:14.33 |
| | so yeah, it's fixed in master, thanks | 15:14.43 |
| | about the backspace thing, is it on purpose that it was removed? | 15:15.59 |
| ator | yes, it was removed on purpose | 15:16.24 |
| | to make the keybindings match mupdf-gl, which also has form filling and annotation editing and other features that don't always play nice with hogging 'backspace' for navigation | 15:16.56 |
| | if you want backspace in mupdf-x11, adding it back in is a minor fix (now that you're building from source anyway) | 15:17.29 |
| | in platform/x11/pdfapp.c add a line "case '\b':" just before the "case 'b':" line | 15:18.51 |
| ubitux | nah it's ok, i can live with it; but what's the de-facto opposite of space then? | 15:19.52 |
| | up arrow looks like the opposite of down arrow, but since that bug it appears that down is not exactly the same as space (not sure why though) | 15:20.36 |
| ator | space and b | 15:20.40 |
| ubitux | ok, LGTM :) | 15:20.55 |
| ator | , and . are other options | 15:21.00 |
| | as well as pgup/pgdown | 15:21.04 |
| ubitux | ah yeah it's in the man, my bad | 15:21.24 |
| ator | one of the sets does 'smart scrolling' when zoomed in, the other set just changes page but not scroll location | 15:21.52 |
| ubitux | oh and arrow actually request some page scrolling, but by side effect trigger the next page when the page fit | 15:21.52 |
| | last q: any plan to release a 1.16.2 or 1.17.x ? | 15:24.56 |
| ator | ubitux: yes, but no date decided yet | 16:04.43 |
| ubitux | ok | 16:05.00 |
| avih | sumatra pdf (uses mupdf internally) also has this default behavior where if the display is non-continuous but the page is zoomed, then scrolling down "jumps" to the next page when reaching the bottom of the current page. i always found this behavior jarring and highly inconvenient. either stay on this page, or switch to continuous automatically IMO. | 16:11.46 |
| ubitux | i hate the jump to the next page while page scrolling | 16:25.24 |
| | thought, i'm fortunate it existed as a workaround for the other bug :P | 16:25.44 |
| ator | ubitux: page down should still work (it doesn't do smart scrolling, which is where the bug was) | 16:34.29 |
| | mupdf-gl does not have the switch-to-next-page-at-bottom when scrolling | 16:34.40 |
| ubitux | ah, wait | 16:35.33 |
| | so… the documentation says: | 16:35.47 |
| | . pgdn space | 16:35.50 |
| | Go to the next page. | 16:35.52 |
| | but this is not actually the same thing? | 16:35.58 |
| | and indeed, pgdn works as well | 16:36.24 |
| ator | https://mupdf.com/docs/manual-mupdf-gl.html | 16:37.47 |
| avih | ator: fwiw, this is a complete external mujs wrapper to make the APIs fully utf8. it's transparent by default except alloc/actx are not used (please expose the memory functions as public), and callbacks which need manual wrapping https://github.com/avih/mpv/blob/experiments-avih/player/mujsutf8.h | 16:46.07 |
| | and that's my current proposed patch to mujs itself (it does expose the alloc functions): https://0x0.st/imD8.txt | 16:47.35 |
| | (missing docs yet, so not yet a PR, but i think the code is complete up to the limits we set with adding builtin utf8 support) | 16:48.27 |
