#current_file ⇒ Object (readonly)

During a compile this will return the current top-level file being compiled

Examples:

Origen.generator.compiler.current_file   # => Pathname

Instance Method Details

#_get_binding(opts, &block) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

#compile_file(file, options = {}) ⇒ Object

Compile the supplied file if it is an erb template writing the compiled version to the destination directory. If the file is not an erb template it is simply copied un-altered to the destination directory. File must be an absolute path to the file.

#compile_inline(file, options = {}) ⇒ Object

Where compile will place the compiled content in an output file, this method will return it as a string to the caller (i.e. without creating an output file)

It expects an absolute path to a single template file as the file argument.
