Cast only if not channelling

[Jundran-bonechewer]

Is it possible to create a macro to cast a spell only if another spell is not channelling? Specifically cast arcane blast only if not channelling arcane missiles. I want to avoid wasting channelling spell by breaking it before it’s done channelling.

Nochanneling Macro

Prevent casting when CHANNELING SPELL is channeling.

#showtooltip
/stopmacro [channeling:CHANNELING SPELL]
/cast SPELL

Prevent casting when ANY SPELL is channeling.

#showtooltip
/stopmacro [channeling]
/cast SPELL

/stopmacro [channeling]

This kind of construction works differently and might fail sometimes.
NoChanneling switch works better.
