Did you have a look a 'demo/Cpp/11-ManualBufferFilling', there it is explained how a feeder or gavager can help out. The example 'lexer-point.cpp' shows how simply to point to a piece of allocated memory. For plain C look at 'demo/C/11-ManualBufferFilling'.

Hi! I really want to use Quex in a project, but I'm having a problem with lexing large input programs. The buffer always fills up to the buffer limit specified in the configuration, but I want to be able to support arbitrary file sizes. This happens even if I create a ByteLoader from a file. Quex just loads it up to the buffer limit. I'm writing this in C, and using a UTF-8 converter. For context, I am given the entire program as a char* string in memory (not a file!). The lexing works perfectly...

Still does not work here on python3.8. It does on python 3.9. Maybe is my environment? However I am happy with it.

OK, I am on it. However, on my linux machine I am not able to reproduce the error. I will try to submit a tar file this evening with a current stable version of Quex. If I get a chance, I am also investigating on MacOs.

I am not an end-user of quex. I was only looking into it as part of doing some maintenance works on Homebrew. Homebrew has had a quex build formula for a long time but until recently it was using a python-2 version (which has been deprecated in homebrew) and am just trying to get a reliable python 3 version integrated. See: https://github.com/Homebrew/homebrew-core/blob/master/Formula/quex.rb As mentioned above we are now using 0.71.0 but are using it with python 3.7 (the earliest homebrew supports)...

This weekend, sorry.

I will look into it this weekend. Python 3.9 should be supported, then. Can you please, send me your use-case?
-
Is there documentation about what python versions are supported now? I took a look at updating the homebrew formula for quex. Homebrew has python 3.7, 3.8, and 3.9 available currently. I hit some immediate issues with 3.8 but that seems to be fixed if I backported one little fix from the git head, but I'm not sure if that is really a complete fix for 3.7 use: https://github.com/Homebrew/homebrew-core/pull/70789 Of course best would be an upstream release with an explicit indication of what python...

Sorry, for the delay. I might have a look into it the next couple of days.
