In Dyalog RIDE, I know how to set breakpoints that will halt execution on specific lines in the APL source. Is there a way to make a breakpoint conditional so I can stop at a line only if a particular set of conditions are met, e.g. 0<+⌿⍵?
There's no IDE (or RIDE) support for this, but with a simple change to the source code, you can achieve the effect.
In a tradfn:
:If 0<+⌿var
🔴 :Endif
In a dfn:
0<+⌿⍵:{
🔴 }⍬
If the condition doesn't hold, we skip the line that would have stopped execution.
