AutoHotkey Community

For internal check of given version of autohotkey, how about of an #version directive instead of the #v2 directive?If the version used to create is newer than the one which currently interprets the script, it could automatically start a user defined subroutine or if not any defined, the default one of autohotkey could be executed automatically. The check would be done before interpreting of script, as first.

It's an interesting idea. Although the benefits don't seem huge, the implementation might be simple (except for the part about running a user-defined subroutine -- instead, it would probably just show an error dialog).

I'll put it on the to-do list for further consideration. Thanks.

It should be flexible:
#version 1
#version 1.0.44
#version 1.0.45.03
#version 2
and so on.

I have a function that does it.Can be easily extended.

Yes toralf, I use on my own scripts also a version check of autohotkey. But the advantage on having the #version directive would be that AutoHotkey loads all included scripts and takes all #version directives in to the oldest one for checking.
Also, libraries without having an autoexecution area could have also easily an version check, before anything other on the script would be executed.

Good point.

Although that would be more complicated to implement, I've made a note of it.

Part of the problem is that old versions of AutoHotkey can display syntax errors when they encounter new syntax, but they do so before all included files have been looked at. Since changing this would probably require a major redesign of script loading and parsing, I think #version should simply display a version error if #version is encountered before anything else that would cause a syntax error.

Thanks for the ideas.

Hope this will be added in the near future. It would add another layer of version documentation, which is not unimportant. And the sooner it gets implemented, the better is it. But I nearly think, its too late.

Edit:

I know, Chris is not maintaining anymore. But this is a general answer, not to him only.
Any AutoHotkey version not supporting the directive should not run the script. If you have an old version installed and have a script written for a newer version, its perfectly ok if the old AHK cannot run the script, because not knowing the version directive. So it is a big plus.
