Yes, webapps. Readability and usability less important than dark theme.

[fpc-devel] Problem with importtl

[gabor via fpc-devel]

I try to import a type library using "importtl" but it fails - ends with 
EAccessViolation exception. I am using fpc trunk from today. I have 
tried importing different libraries but with no success. Could someone 
confirm the problem?

Unfortunately, msdxm.ocx file does not contain type library. Try 
msdxm.tlb instead.

[fpc-devel] ViewVC not working

[gabor via fpc-devel]

Can't open ViewVC page from SVN repository - I'm getting 404 error. Is 
the website down or is it a temporary problem?

I use this address: https://svn.freepascal.org/cgi-bin/viewvc.cgi/

[fpc-devel] C library header - var vs pointer for function arguments

[gabor via fpc-devel]

I'd like to provide some fixes for packages that are headers for c 
libraries. When and should I use the "var" argument for function 
arguments that return a value, or should I always use pointers 
(excluding arguments that might accept nil)?


Eg:
function Foo(var A: Integer): Integer;
vs
function Foo(A: PInteger): Integer;

Consider backwards compatibility in fixes


Good point, thanks. However, I mean non-existent / incorrect / not 
up-to-date declarations.

It's best to use pointers, but you can always provide overloads with var
arguments.

And as Dmitry Boyarintsev pointed out, don't change existing signatures for
backwards compatibility.

Michael.


Thanks. I'll use pointers.

Re: [fpc-devel] threadvar vs docs

W dniu 2024-10-18 o 15:27, Nikolay Nikolov via fpc-devel pisze:


In C (with gcc) it's possible to give them initial value, other than 0:

__thread int i = 5;

But it doesn't seem to be supported by FPC for threadvars. And I don't 
know about Delphi. FPC's thread initialization does indeed include code 
for copying the initial values, when creating a thread. Maybe it's for 
compatibility with thread-aware C libraries (including e.g. glibc), 
linked with the program, or for a possible future support for 
initialized threadvars in FPC?


Nikolay


Maybe variables containing managed types, such as dynamic arrays could 
be a problem in this case?
