I haven't done anything for mIRC in a long time. However, these days, I decided to test if it was possible to create dlls for mIRC using the Nim programming language (which I've been using a lot).
From these experiments, the mdlldk
package came out, which is aimed at developing dlls for mIRC. The full description can be found in the link above, so as not to make your reading repetitive here.
The package is open source and MIT licensed. It has good documentation and examples
(one example for now). The other code, which is in the tests folder, is more for debugging mIRC and the package.
So here's an invitation for anyone interested in the Nim programming language and using it to develop dlls for mIRC.
