Crate ironwork_syntax 

ironwork for COBOL: from fixed-format source text to a syntax tree. Nothing here knows about storage or execution.

Modules

ast

bms

BMS map source (the DFHMSD, DFHMDI and DFHMDF assembler macros) as a mapset model, and the COBOL symbolic map a program COPYs for it.

copy

COPY and COPY REPLACING, applied to the logical text before it is lexed. Matching is by text-words, as the standard defines them, and replacement edits the text itself, so a pseudo-text such as ==:TAG:== can replace part of a word like :TAG:-RECORD.

lexer

parser

source

Fixed-format reference format: columns 1-6 sequence, 7 indicator, 8-72 program text, 73 on ignored. The result is one logical text with continuation lines joined, and the options of any CBL or PROCESS cards ahead of the program.

system

The copy members IBM’s translators and products supply, as ironwork’s own declarations of the layouts and names IBM documents: Db2 13 for z/OS SQL Reference (“The included SQLCA”, “The included SQLDA”), CICS TS Data Areas (“EIB - EXEC interface block”) and CICS TS Application Programming Reference, “BMS-related constants” (DFHAID, DFHBMSCA). A library member of the same name is found first, as it would be ahead of the system library on z/OS.

Structs

Error

Pos

Where a diagnostic points: 1-based source line and column.

Functions

parse

The first program in the source.

parse_all_with

Every program in the source, in order, nested programs after the one that contains them.

parse_with

The first program in the source, with COPY members resolved from libraries.
