find-graphical-system-path in Miscellaneous

Finds a platform-specific (and possibly user- or machine-specific) standard filename or directory.

See also find-system-path, section 11.3.2 in PLT MzScheme: Language Manual.

• (find-graphical-system-path what) -> path or #f
   what : symbol in '(init-file setup-file x-display)

  The result depends on what, and a #f result is only possible when what is 'x-display:

  • 'init-file returns the path to the user-specific initialization file (containing Scheme code). The directory part of the path is the same path as returned for 'init-dir by MzScheme's find-system-path (see Pathnames, section 11.3.2 in PLT MzScheme: Language Manual). The file name is platform-specific:

    • Unix and Mac OS X: .mredrc

    • Windows: mredrc.ss

  • 'setup-file returns the path to the file containing resources used by get-resource; obsolete.

  • 'x-display returns a ``path'' whose string identifies the X display if specified by either the -display flag or the "DISPLAY" environment variable when MrEd starts under X. For other platforms, or when neither -display nor "DISPLAY" was specified, the result is #f.
