flymake: Interaction with other modes

 
 5.9 Interaction with other modes
 ================================
 
 The only mode flymake currently knows about is ‘compile’.
 
    Flymake can be configured to not start syntax check if it thinks the
 compilation is in progress.  The check is made by the
 ‘flymake-compilation-is-running’, which tests the
 ‘compilation-in-progress’ variable.  The reason why this might be useful
 is saving CPU time in case both syntax check and compilation are very
 CPU intensive.  The original reason for adding this feature, though, was
 working around a locking problem with MS Visual C++ compiler.
 
    Flymake also provides an alternative command for starting
 compilation, ‘flymake-compile’:
 
      (defun flymake-compile ()
        "Kill all flymake syntax checks then start compilation."
        (interactive)
        (flymake-stop-all-syntax-checks)
        (call-interactively 'compile))
 
    It just kills all the active syntax check processes before calling
 ‘compile’.
