OK, so I have tried to install llvm-14 in my linux distro and linked theide with its libclang - and things started to work even with preamble, totally fine, fast, just as in Windows (except some fixing of include paths to get autocomplete of std:: stuff, but nothing serious; that part is under development anyway).
(Note - if you wonder why I am speaking about preamble so much - preamble is a flag that you give to libclang that makes it create implicit precompiled header in the first file parse. This is very important for autocomplete because we do that parse in background thread and when user needs the autocomplete, all is ready and fast. So it is really important for comfort - using preamble, autocomplete is almost instant (~400ms). Without it can take 1-5 seconds to popup).
So my conclusion: I will only use preamble only when I detect libclang 14, I do not care about outdated distros. Autocomplete will be slow if libclang 14 is not available.
Latest ubuntu has 14, so... Maybe one last thing to try is whether libclang 13 works, if somebody has time to test.
This will be hell in the installation script (to get the most fresh libclang for given distro or even disable libclang completely), but what can we do...
I really would appreciate help with installation script BTW!

Hello Mirek,
libclang-14 requierments explains a lot. On Manjaro current available version is libclang-13, so maybe the issues mentioned by me in my previous message are caused by insufficient libclang library version. Manjaro is rolling release, it means that it has relatively new packages. So, the general adoption of libclang-14 in the Linux word is low.
Quote: So it is really important for comfort - using preamble, autocomplete is almost instant (~400ms). Without it can take 1-5 seconds to popup).
I can confirm that CTRL+Space take some time to appear on the screen. Is there a way to optimize it for example by pre generating auto complete or using caching? Also, I think user should be somehow inform that something is generating under the hood. For me it looks like TheIDE is unresponsive after using Ctrl+Space. Moreover, ~400ms might be too much. You need to take into consideration that it calculates that time on your CPU. With weaker CPU's this value might be bigger. So, maybe we could also optimize this using similar techniques I proposed.
Could you also tell me from where on Windows I can download libclang-14? I would like to have comparison.

Hello Mirek,
I tested on the latest commit and from my perspective the performance is better, however my feelings are that Assist++ is not supper responsive and you can fell that it takes some time to appear. Could you add a release log file that will measure the Assist++ opening time? From request to appear.
For the rest of the issues I have mentioned in my previous message, everything is the same. Here is screenshot from String without AString methods:
The console.${Assist++} doesn't open assist.

Hello Mirek,
Thanks for the update, I will play with llbm_ide branch.
Quote:Not everything is happy valley though, theide requires far more powerful HW than before. Reindexing consumes a lot of memory (around 6GB) - that is understandable considering we are running 32 C++ compilers in parallel to do it. Also autocomplete is sort of lazy in large projects as compared to my in-house parser, but that is the price to pay I guess...
As, I understand the number of C++ compiler jobs depends on HYDRA threads parameter. Could it be limited to one thread only if HYDRA threads are set to one? It would be good if TheIDE will still work on all these ARM devices that has single CPU. With only one thread running, the memory requirements should also be lower.
We have a lot of users from countries where there are difficulties to have access to modern hardware. In such cases TheIDE should work fine, even if indexing will take longer.
Scanning operation takes some time, it would be good to let user know that something is happening under the hood. We should avoid situation when user fells confusion. I think we can introduce following things:
- scanning progress is present in status bar (A lot of ide's are using this option...). Status bar is visible by default.
- CTRL+SPACE should indicate that the scanning is in progress and symbols are not ready yet. The information can be displayed in tooltip window.
- CTRL+SPACE should indicate that there are no symbols after scan (please back to my previous message). The same situation it can be displayed in tooltip window. This is exactly what I have presented in my previous message.

CPU usage.
TheIde is heavily using CPU even if I change one character.
This is a problem for my ten-years-old laptop.
Is it possible to add an options, which will
1) disable libclang completely.
2) limit reindexing to a "Save" command.
3) keep libclang running all the time.
TIA.
Regards,
Novo

Hi,
I had to move #include <X11/Xlib.h> in GtkApp.cpp in order to compile in Windows with clang:
#include <CtrlCore/CtrlCore.h>
#ifdef GUI_GTK
#include <X11/Xlib.h>
#define CATCH_ERRORS 1
Additionally, compilation fails to missing include in MSBT22x64:
C:\upp-16323\upp.src\uppsrc\ide/clang/clang.h (5): fatal error C1083: Cannot open include file: 'clang-c/Index.h': No such file or directory
Best regards,
Tom

Hi Mirek,
Each time I have e.g.:
void LeftDown(Point p, dword keyflags) override {
I get a row: "WARNING: EMIT" in my Navigator. If I remove the override, it goes away. (I do not think this is anything new, but it shows up in the latest version too.)
Second, there are some warnings (at least on MSBT):
C:\upp-git\upp.src\uppsrc\Core\Other.h(123): warning C4267: 'argument': conversion from 'size_t' to 'int', possible loss of data
C:\upp-git\upp.src\uppsrc\Core\Other.h(143): warning C4267: 'argument': conversion from 'size_t' to 'int', possible loss of data
C:\upp-git\upp.src\uppsrc\CtrlLib/DropChoice.h(83): warning C4099: 'Upp::PopUpList::Popup': type name first seen using 'struct' now seen using 'class'
C:\upp-git\upp.src\uppsrc\CtrlLib/DropChoice.h(54): note: see declaration of 'Upp::PopUpList::Popup'
Best regards,
Tom
