Edit Command

rascal-0.34.0

Open an editor for a Rascal module

This opens an editor for the given module name. For every context of running Rascal, this could mean different things:

On the Unix commandline the ${EDITOR} environment variable will be used to open a file. If that file is present in the local file system, it is opened by running ${EDITOR} /absolute/path/to/module.rsc, but if the file is hidden behind an opaque Location scheme, then it is first copied to a temporary file on the local file system, and then opened.
In Eclipse, the eclipse editor framework is used to open an editor for the file. If it is a so called "resource" in the eclipse file system, and editable file is opened with all the Rascal language support. If the file is from an embedded library (inside a jar) then the contents of the file are shown in a similar editor, but read-only.
In VScode a similar experience is provided as in Eclipse, but the editor for library files does not know it is read-only.
