tapping CTRL not working in macros (Ergodox)

[kaimi]

I’m using @cub-uanic’s Ergodox code, but apparently it’s most likely a general issue: cub-uanic#6.

In this macro

MACRO( I(50), T(LCTRL), T(LCTRL), W(255), W(255), T(ENTER), END)

https://github.com/kaimi/tmk_keyboard/blob/1.0.1/keyboard/ergodox/keymap_neo.h#L402

only the ENTER is registered, both LTCTRL are silently omitted. XEV output:

KeyPress event, serial 32, synthetic NO, window 0x3a00001,
    root 0xa2, subw 0x0, time 27317479, (-128,418), root:(559,457),
    state 0x0, keycode 36 (keysym 0xff0d, Return), same_screen YES,
"   XLookupString gives 1 bytes: (0d) "
"   XmbLookupString gives 1 bytes: (0d) "
    XFilterEvent returns: False

KeyRelease event, serial 32, synthetic NO, window 0x3a00001,
    root 0xa2, subw 0x0, time 27317535, (-128,418), root:(559,457),
    state 0x0, keycode 36 (keysym 0xff0d, Return), same_screen YES,
"   XLookupString gives 1 bytes: (0d) "
    XFilterEvent returns: False

I tried seperate D(LCTRL), U(LCTRL) and even reducing the macro to just T(LTCRL), T(ENTER). Don’t work either.

Yes, you can't register modifier only. In macro modifiers get valid only when other key is pressed. This is intentional design.

To tap a mondifier we'll need to add some new notation. I'll look into this for next revision.

WORKAROUND: You can use function instead of macro.

Oh, that’s too bad. Thanks for the quick reply.

How do I simulate the key presses in a function, if I might ask?

This commit e852582 probably fixed this problem.
