XLang is a parser framework for language modeling.
It handles AST MVC, so as a language developer, you can focus on more important things, such as tuning the grammar.
input:
(-b+(b^2-4*a*c))/(2*a)
output:
echo "(-b+(b^2-4*a*c))/(2*a)" | ./bin/XLang -d | dot -Tpng -oquadratic.png
Unix tools and 3rd party components (accessible from $PATH):
gcc flex bison valgrind cppcheck doxygen graphviz ticpp
Environment variables:
- $INCLUDE_PATH_EXTERN -- where "ticpp/ticpp.h" resides
- $LIB_PATH_EXTERN -- where "libticppd.a" resides
Ubuntu packages:
- sudo apt-get install flex
- sudo apt-get install bison
| target | action |
|---|---|
| all | make binaries |
| test | all + run tests |
| pure | test + use valgrind to check for memory leaks |
| dot | test + generate .png graph for tests |
| lint | use cppcheck to perform static analysis on .cpp files |
| doc | use doxygen to generate documentation |
| xml | test + generate .xml for tests |
| import | test + use ticpp to serialize-to/deserialize-from xml |
| clean | remove all intermediate files |
