GML [Solved] Is there an equivalent to #define name()?

[Hieran_Del8]

I'm interested in having inline evaluations, but I'm not sure if GMS has something similar to the define keyword in C.

In C, it would look something like:

enum char_type {
    Word = 0x100,
    Digit = 0x200 | Word,
    Letter = 0x400 | Word,
    ...etc...
};
#define char_is_word(c) (c & char_type.Word)

...

if (char_is_word(ch)) {
    ...
}

Is there something similar in GML? Like this:

enum char_type {
    Word = 0x100,
    Digit = 0x200 | Word,
    Letter = 0x400 | Word,
    ...etc...
}
#macro char_is_word(c) (c & char_type.Word)

...

if (char_is_word(ch)) {
    ...
}

The closest you can get to that is using functions.

Thanks, that answers it for me!

Since you mention inline evaluation, perhaps you can investigate the use of gml_pragma("forceinline") in the function definition.

This is the closest alternative to a macro with parameters. Thanks for the lead!

GMEdit has an "#mfunc" preprocessor that helps with stitching macros together to achieve the effect of macros with arguments - e.g.

#mfunc char_is_word(c) (c & char_type.Word)
var z = char_is_word(c);

would be converted to and from

//!#mfunc char_is_word {"args":["c"],"order":[0]}
#macro char_is_word_mf0  (
#macro char_is_word_mf1  & char_type.Word)
var z = char_is_word_mf0 c char_is_word_mf1;

in saved code.

This editor looks really nice! I'll give this a try, thanks for the suggestion!
