substitute-in-file-name is a built-in function in `C source code'. (substitute-in-file-name FILENAME &optional PARSEINFO) Substitute environment variables referred to in FILENAME. `$FOO' where FOO is an environment variable name means to substitute the value of that variable. The variable name should be terminated with a character not a letter, digit or underscore; otherwise, enclose the entire variable name in braces. If `/~' appears, all of FILENAME through that `/' is discarded. On VMS, `$' substitution is not done; this function does little and only duplicates what `expand-file-name' does. If PARSEINFO is not NIL, it is a list used or reused for storing parsing information (it is extended as necessary). Elements 2N point to positions in the original string, Elements 2N+1 to corresponding positions in the substituted string. [...] Something like that. And then one looks for the last [x,0] pair in the list, and x is the position from which to shadow. No consing done except when the syntax changes on entry. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-devel
