Detailed Description
The lex_yacc
module allows you to create scanners and parsers via the POSIX tools lex
and yacc
, respectively. These tools are closely related and share a number of properties, which is why they are represented by a single module.

Property Documentation
Whether compiler warnings are displayed.
Because lex
and yacc
are known to produce files that will trigger compiler warnings, such warnings are suppressed by default. Set this property to true
if you want to see them.
Default: false
This QML property was introduced in Qbs 1.8.
If this property is true
, the prefix yy
normally used for the generated lexer and parser functions is replaced by the base name of the file provided as input to lex
and yacc
, respectively.
Enable this property if you want to use more than one lexer or parser in a single product.
Note: Enabling this property requires that the associated lexer and scanner source files have the same base name. It also assumes a variant of lex
that supports the non-POSIX option -P
, such as flex
.
Default: false
