How to get the project's file name?

[Bee Jay]

As shown in the above image, OmniPascal has a feature to set a project by selecting a .lpr or .dpr file. Is there a way to obtain the project's file name as a variable to be used in a task? If it has no project file set, then simply return an empty string. Perhaps something like:

• ${omnipascal.projectfilename}: File name (with extension) of the project file.
• ${omnipascal.projectfilebase}: File base name (without extension) of the project file.
• ${omnipascal.projectfileextension}: Only the extension part (.lpr/.dpr) of the project file.
• ${omnipascal.projectfilepath}: Only the directory or path part of the project file with absolute path.
• ${omnipascal.projectfilepathrelative}: Only the directory or path part of the project file with relative path.
• ${omnipascal.projectfile}: Complete project's file name (includes all parts with absolute path).
• ${omnipascal.projectfilerelative}: Complete project's file name (includes all parts but with relative path to workspace folder).

Is it possible? At least as environment variables.

Thank you.
