= Integrate with tools that check files for problems.
Many file-formats have "lint" tools that check for common problems and point out
where they occur. Most of these tools produce output in the traditional message
format:
----
{filename}:{line}:{column}: {kind}: {message}
----
If the 'kind' field contains 'error', the message is treated as an error,
otherwise it is assumed to be a warning.
The `:lint-buffer` and `:lint-selections` commands will run the shell command
specified in the `lintcmd` option, collect the result in the `*lint-output*`
buffer, and analyze it. If `toolsclient` is set, the `*lint-output*` buffer will
be displayed in the named client.
Each reported error or warning causes a marker to appear in the left-hand
margin of the buffer that was checked. When the main cursor moves onto that
line, the associated messages are displayed. If they get distracting, you can
turn off the markers and messages with the `:lint-hide-diagnostics` command.
You can also use `:lint-next-message` and `:lint-previous-message` to jump
between the lines with messages.
