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.
Relevant File Tags
| Tag | Auto-tagged File Names | Since | Description |
|---|---|---|---|
"lex.input" | *.l | 1.6 | Source files with this tag serve as inputs to the lex tool. |
"yacc.input" | *.y | 1.6 | Source files with this tag serve as inputs to the yacc tool. |
Property Documentation
enableCompilerWarnings : bool |
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 property was introduced in Qbs 1.8.
lexBinary : string |
The file path of the lex tool.
Default: "lex"
lexFlags : stringList |
Additional command-line options for the lex tool.
Default: []
lexOutputFilePath : string |
The output file for the lex tool.
This corresponds to %option outfile in the .l file. If %option outfile is set in the .l file then this property is ignored.
Default: undefined
This property was introduced in Qt 1.12.
outputTag : string |
uniqueSymbolPrefix : bool |
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
yaccBinary : string |
The file path of the yacc tool.
Default: "yacc"
yaccFlags : stringList |
Additional command-line options for the yacc tool.
Default: []
yaccOutputFilePath : string |
Main output file for the yacc tool.
This corresponds to %output in the .y file. If %output is set in the .y file then this property is ignored.
Default: undefined
This property was introduced in Qt 1.12.
