@node Flymake
@section Finding Syntax Errors On The Fly
@cindex checking syntax
Flymake mode is a minor mode that performs on-the-fly syntax
checking for many programming and markup languages, including C, C++,
Perl, HTML, and @TeX{}/La@TeX{}. 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}.
