Ditto, but of course it depends on the machine. Same here, I don't see any kind of lag with that file. But yeah, depends a lot on the machine's power. Myself, I've found the biggest slowdown is when having lots of tags files, say more than 10 maybe. If I have all my Vala tags (the ones on the Wiki) loaded, Geany basically becomes unusable. IIUC the tags files are not re-loaded so the problem here suggests symbol lookup problems rather than parsing problems. Actually, IIRC Tagmanager updates an array holding all workspace tags every time an update is done, so having many tags file or many open files of a same filetype *may* (?) reduce the performances. No guarantees on that though, there are too many dark corners in Tagmanager (:-') Are you saying that it re-reads all open tags files every time it re-parses a source file? That would certainly make it slow. And if it is just an array, unless the array is indexed or sorted then searching it would be slow for computing the auto-completions. 1) tm_workspace keeps a sorted array of all non-global tags, that is rebuilt on each reparse [1]. This needs to rebuild and sort an array holding all tags (I suspect that this may be slow with many tags), but don't need reparsing anything. 2) As Matthew said in another mail, tm_tags_find() uses bsearch() [2] so it's not that slow upon search. Note however that scope completion is a complete other topic -- BTW it's still broken... :/ Cheers, Colomban [1] tm_workspace.c:tm_workspace_update() [2] tm_tag.c:tm_tags_find() ___ Geany-devel mailing list Geany-devel@uvena.de https://lists.uvena.de/cgi-bin/mailman/listinfo/geany-devel

Hi Colomban, Thomas,
Hey Lex, everyone,
I disagree, it is a bad idea to turn off a setting that changes the
behavior. The user is likely to be confused by the unexpected change
in behavior (new symbols no longer in autocompletes, new types not
being highlighted etc). Having it automagically turn off is bad. At
most, pop up a dialog suggesting turning it off and noting where, but
only ever once per session.
Hum, right, automagic might not be good, asking the user is always better.

0001-Per-document-real-time-symbols-setting.patch:
Adds a per-document setting for real-time updates and a menu item in the

this whole thing important enough to break string freeze less than a

PS:
Although I have a great idea for an animated paper clip in the bottom
right corner that can suggest it every couple of seconds ... :)
Hehe, I like the idea... :D
Colomban is right in trying to evaluate where Nicks problem is first,
thats far more likely to be productive, this sort of thing is the last
option not the first.
BTW, after Nick's answer, it looks very weird to me, like if regexes was
eeaalyyy slow on Windows (or

That would certainly make it slow. And if it is just an array, unless the array is indexed or sorted then searching it would be slow for computing the auto-completions.

It's a big document though, still perhaps the HTML tag parser performance could be improved. I think 5s is weird in the first place. I know geany.html is 6.5k-lines file, and that it may have say, 150 tags, but 5s seems way too much IMHO. Maybe we should try to find out why this is so slow on your machine, there might show a Geany bug, performance problem or something else. * What kind of machine did you run (basically, CPU's MHz) * Had you many HTML files open, with many tags each? * Had you many non-HTML files open? ...and any information that might be useful (:-') (BTW, I've seen HTML tag parser is regex-based, maybe that's particularly slow?) But now we have tag reparsing, editing geany.html becomes painful. I know we can disable reparsing, but what else could we do to improve the situation? It's not urgent to solve this problem, unless we want to make reparsing off by default. I like Thomas' idea, see other mail.

Re: [Geany-devel] editing big files can be too slow with tag reparsing
[...] How about automagically disabling auto-reparsing per-file if it takes too long (1s?) at runtime? Without needing to change the setting that is. I like the idea. Hi Colomban, Thomas, I disagree, it is a bad idea to turn off a setting that changes the behavior. The user is likely to be confused by the unexpected change in behavior (new symbols no longer in autocompletes, new types not being highlighted etc). Having it automagically turn off is bad. At most, pop up a dialog suggesting turning it off and noting where, but only ever once per session. Although I have a great idea for an animated paper clip in the bottom right corner that can suggest it every couple of seconds ... :) Colomban is right in trying to evaluate where Nicks problem is first, thats far more likely to be productive, this sort of thing is the last option not the first.

I'm always surprised what users can overlook, but if we notify them, it doesn't matter how unobservant they are :) Colomban is right in trying to evaluate where Nicks problem is first, thats far more likely to be productive, this sort of thing is the last option not the first. I agree. Also Matthew's perceived slowness with lots of tags loaded needs checking, is it reloading them all the time (as Colomban seemed to suggest) or does the symbol table used by tagmanager have O(1), O(log), O(N) or worse performance.

I'm too afraid to go back into the TagManager code, but IIRC it uses a sorted GPtrArray. I think for each new tag added it qsort()s the array and also removes duplicates by looping over the whole array. Lookups are done with bsearch() on the array I think. Not sure if that matters or is what you asked :) Cheers, Matthew Brush ___ Geany-devel mailing list Geany-devel@uvena.de https://lists.uvena.de/cgi-bin/mailman/listinfo/geany-devel
