Grammar functions are used in expressions when customizing field mappings through Source Manager. The grammar is defined using a variant of the BNF (Backus-Naur Form) notation. The rules of that notation are as follows:
The grammar is defined in terms of a set of tokens, which are logically distinct classes of entities from the point of view of parsing the grammar.
General instances of tokens are represented as the name of the token in underscore-separated italic text: token_instance
Literal text (such as keywords) are written without quotes or any other delimiters in plain font: literal
