It is somewhat analogous to Flyspell +mode, which performs spell checking for ordinary human languages in a +similar fashion (@pxref{Spelling}). As you edit a file, Flymake mode +runs an appropriate syntax checking tool in the background, using a +temporary copy of the buffer. It then parses the error and warning +messages, and highlights the erroneous lines in the buffer. The +syntax checking tool used depends on the language; for example, for +C/C++ files this is usually the C compiler. Flymake can also use +build tools such as @code{make} for checking complicated projects. + + To activate Flymake mode, type @kbd{M-x flymake-mode}. You can move +to the errors spotted by Flymake mode with @kbd{M-x +flymake-goto-next-error} and @kbd{M-x flymake-goto-prev-error}. To +display any error messages associated with the current line, use +@kbd{M-x flymake-display-err-menu-for-current-line}. + + For more details about using Flymake, see @ref{Top, Flymake, +Flymake, flymake, The Flymake Manual}. + @node Debuggers @section Running Debuggers Under Emacs @cindex debuggers |
