ANTLR4 grammar¶
Some of the code uses ANTLR generated code to parse expressions at runtime. The grammar files are located in * src/expressions/antlr-interface/Expr.g4 * src/libs/antares/additionalConstraintRhsExpression/HoursField.g4
How to generate code from the grammar¶
ANTLR4 4.13.2 is used to generate the code. Note that using a different version results in a different code, possibly incompatible with antlr4-runtime.
You may use the convenience CMake target antlr_generate_all to re-generate from all grammars.
cmake -B <build> -DANTLR_JAR_PATH=path/to/antlr.jar [other options]
cmake --build <build> --target antlr_generate_all
See here for some general documentation about generating C++ code from an ANTLR4 grammar.
Formatting¶
Please DO NOT format the generated code.
