Setting a conditional breakpoint in Dyalog RIDE

Question

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<+⌿⍵?

Answer 1

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.
