Load the package:

Wolfram Language code: Needs["CodeParser`"]

Parse a string of Wolfram Language code into an abstract syntax tree:

Properties & Relations  (1)

The following three code strings parse in a similar manner:

Wolfram Language code: e1 = CodeParse["f[x]"]
Wolfram Language code: e2 = CodeParse["f@x"]
Wolfram Language code: e3 = CodeParse["x//f"]

The location of the tokens in the source are different for each source, so they are not identical:

Wolfram Language code: e1 === e2 === e3

Possible Issues  (1)

Wolfram Language code: Needs["CodeParser`"]
  • A string representing a file path is treated as code.
    • Wolfram Language code: CodeParse["ExampleData/Collatz.m"]
  • File paths must use the File wrapper.
    • Wolfram Language code: CodeParse[File["ExampleData/Collatz.m"]]
