Watch command
Yarner has a subcommand watch to automatically build a project after files changed.
This may be particularly convenient when switching back and forth
between Markdown editing and code editing with reverse mode.
Usage
To start watching, run subcommand watch:
> yarner watch
Yarner will do one forward build and then watch the detected source files, as well as the generated code files, for changes. When source files change, Yarner runs a forward build. When code files change, it runs a reverse build.
The config file Yarner.toml is watched as a source file,
thus a forward run will be done on changes.
To stop watching, press Ctrl + C.
Reverse pass
In watch mode, a reverse build is immediately followed by a forward build, but exclusively for the documentation output. This way, code changes are immediately reflected in the documentation.
Error handling
When watching a project, some errors are handled less strict in order to not abort watching unnecessarily. Instead of aborting with an error, a warning is printed. In particular, this applies to plugin errors.
