lastAssignmentToVariable

csoundengine.csoundlib.lastAssignmentToVariable(varname, lines)

Line of the last assignment to a variable

Given a piece of code (normally the body of an instrument) find the line in which the given variable has its last assignment

Parameters:

• varname (str) – the name of the variable

• lines (list[str]) – the lines which make the instrument body. We need to split the body into lines within the function itself and since the user might need to split the code anyway afterwards, we already ask for the lines instead.

Return type:

int | None

Returns:

the line number of the last assignment, or None if there is no assignment to the given variable

Possible matches:

aout oscili 0.1, 1000
aout, aout2 pan2 ...
aout = ...
aout=...
aout += ...
aout2, aout = ...

Example

>>> lastAssignmentToVariable("aout", r'''
... aout oscili:a(0.1, 1000)
... aout *= linen:a(...)
... aout = aout + 10
... outch 1, aout
... '''.splitlines())
