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.
