errorf
or warnf
will evaluate a format string, then output the result to the ERROR or WARNING log (and only once per error message to avoid flooding the log).
Any ERROR will also cause the build to fail (the hugo
command will exit -1
).
Note that the WARNING will only be printed to the console.
{{ errorf "Failed to handle page %q" .Path }}
{{ warnf "You should update the shortcodes in %q" .Path }}
Note that errorf
and warnf
support all the formatting verbs of the fmt package.
