cmake-parser

This is a project to parse cmake scripts, it will parse script into a list of command invocation.

API

1. expand-argument (arg binding) Expand argument if it contains variable reference. You should provide a variable binding hash-table. Ex. arg: 'Hello ${someone}', binding: 'someone'->'Bob', it will expand to 'Hello Bob'.

2. grammar () Return the cmake grammar.

3. parse-string (str) Parse cmake script string, return a list of command invocation.

4. parse-file (pathname) Parse cmake script file, return a list of command invocation.

Example

(defun common-usage ()
  (let ((binding (make-hash-table :test 'equal))
        (prod (cmake-parser:parse-string "# A demo helloworld
                                          SET(TARGET_NAME \"HelloWorld\")
                                          ADD_EXECUTABLE(${TARGET_NAME} hello.cpp world.cpp)")))
    (loop for call in prod
      do (progn
           (format t "~{~A ~}~%" call)
           (cond
             ((string-equal "SET" (first call))
              (setf (gethash (second call) binding) (third call)))
             ((string-equal "ADD_EXECUTABLE" (first call))
              (format t "bin: ~A, src: ~{~A ~}~%"
                      (cmake-parser:expand-argument (second call) binding)
                      (cddr call)))
             (t (format t "Not Supported Command Invocation")))))))

This will output:

- SET TARGET_NAME HelloWorld 
- ADD_EXECUTABLE ${TARGET_NAME} hello.cpp world.cpp 
- bin: HelloWorld, src: hello.cpp world.cpp
