yacc Command Examples

Generate an LALR parser (in C) with a formal grammar specification file. See also: bison. More information: https://manned.org/yacc.1p.

• Create a file y.tab.c containing the C parser code and compile the grammar file with all necessary constant declarations for values. (Constant declarations file y.tab.h is created only when the -d flag is used):

yacc -d {{path/to/grammar_file.y}}

• Compile a grammar file containing the description of the parser and a report of conflicts generated by ambiguities in the grammar:

yacc -d {{path/to/grammar_file.y}} -v

• Compile a grammar file, and prefix output filenames with prefix instead of y:

yacc -d {{path/to/grammar_file.y}} -v -b {{prefix}}
