I am trying to use some lambdas in functional updates. Simple example would be
parse "update cfoo:foo'[c] from t"
!
`t
falseb
,`cfoo!,((`func;`foo);`c)
What is the `func in that parse tree? With what do I need to replace it in below?
![`t;();0b;(enlist `cfoo)!enlist ((`func;`foo);`c)]
Parsing the same thing as you gives me a different thing than what you have:
q)parse "update cfoo:foo'[c] from t"
!
`t
()
0b
(,`cfoo)!,((';`foo);`c)
Which would look like:
![`t;();0b;(enlist`cfoo)!enlist((';`foo);`c)]
The above comes straight from the `q prompt. You either parsed a different thing or your GUI/IDE changed something in the final output.
The func is nothing else but the ' you are applying to [c].
Here's an example where I have changed the ' with something else:
q)parse "update cfoo:foo/:[c] from t"
!
`t
()
0b
(,`cfoo)!,((/:;`foo);`c)
