flymake: Example---Configuring a tool called directly

 
 4.2.1 Example—Configuring a tool called directly
 ------------------------------------------------
 
 In this example, we will add support for ‘perl’ as a syntax check tool.
 ‘perl’ supports the ‘-c’ option which does syntax checking.
 
    First, we write the ‘init-function’:
 
      (defun flymake-perl-init ()
        (let* ((temp-file (flymake-init-create-temp-buffer-copy
                           'flymake-create-temp-inplace))
               (local-file (file-relative-name
                            temp-file
                            (file-name-directory buffer-file-name))))
          (list "perl" (list "-wc " local-file))))
 
    ‘flymake-perl-init’ creates a temporary copy of the buffer contents
 with the help of ‘flymake-init-create-temp-buffer-copy’, and builds an
 appropriate command line.
 
    Next, we add a new entry to the ‘flymake-allowed-file-name-masks’:
 
      (setq flymake-allowed-file-name-masks
            (cons '(".+\\.pl$"
                    flymake-perl-init
                    flymake-simple-cleanup
                    flymake-get-real-file-name)
                  flymake-allowed-file-name-masks))
 
    Note that we use standard ‘cleanup-function’ and ‘getfname-function’.
 
    Finally, we add an entry to ‘flymake-err-line-patterns’:
 
      (setq flymake-err-line-patterns
            (cons '("\\(.*\\) at \\([^ \n]+\\) line \\([0-9]+\\)[,.\n]"
                    2 3 nil 1)
                  flymake-err-line-patterns))
