Using Walt is very simple. The application has only two required command line options and a third optional one:
walt SOURCE DESTINATION [IGNORE...]
DESTINATION is the target directory where the processed web application will be generated/copied. Files from SOURCE will not be modified.
IGNORE are optional arguments. Any further argument represents a relative path (file or directory) as seen from SOURCE which should be ignored for validation/compilation. However these files are still copied to DESTINATION. This is especially useful for third party libraries whose code you are not responsible for ;-) Also see the "ignore" option in the configuration file.
The behaviour of Walt can be additionally tweaked with configuration files. Walt is looking for files in the following directories and order:
INSTALLDIRis the installation directory of Walt
HOMEis the home directory of the user
SRCis the source directory specified at the command line
If multiple files are found they will be merged where latter files overwrite options of former ones.
INSTALLDIR/walt.json for a sample configuration.
See the Wiki for some information on how to develop plugins for Walt.
At first this application was called BuildJS. However a module with that name already exists in the npm registry so I named the application after the protagonist of my favourite TV show Breaking Bad ;-)
You may also think of walt as an acronym for "website analyzing tool", "website awesome lint tool" or whatever :-)
