[FEA] Implement Optimus parser
argenisleon opened this issue · comments
For convenience, we want to implement a parser that lets the user create and string expression that will be executed inside a UDF function.
For example, a user could write
expr = "SQRT('col_name_1') + SQRT('col_name_2') + 100
This will be parsed to
expr = "op.sqrt(df['col_name_1']) + op.sqrt('df['col_name_2']) + 100

To use the parser
from optimus.expression import Parser
p = Parser()
p.parse(SQRT("col_name"))
