Struct mdbook::preprocess::CmdPreprocessor [−][src]
pub struct CmdPreprocessor { /* fields omitted */ }
A custom preprocessor which will shell out to a 3rd-party program.
Preprocessing Protocol
When the supports_renderer()
method is executed, CmdPreprocessor
will
execute the shell command $cmd supports $renderer
. If the renderer is
supported, custom preprocessors should exit with a exit code of 0
,
any other exit code be considered as unsupported.
The run()
method is implemented by passing a (PreprocessorContext, Book)
tuple to the spawned command ($cmd
) as JSON via stdin
. Preprocessors
should then “return” a processed book by printing it to stdout
as JSON.
For convenience, the CmdPreprocessor::parse_input()
function can be used
to parse the input provided by mdbook
.
Exiting with a non-zero exit code while preprocessing is considered an
error. stderr
is passed directly through to the user, so it can be used
for logging or emitting warnings if desired.
Examples
An example preprocessor is available in this project’s examples/
directory.
