annotate lisp/cus-file.el @ 4448:fd8a9a4d81d9

Support #!, to allow XEmacs to be called as a script interpreter. ChangeLog addition: 2008-01-20 Aidan Kehoe <kehoea@parhasard.net> * Makefile.in.in (SHEBANG_PROGNAME): New variable; a symbol link to the XEmacs binary to tell it it should read a script from stdin. * configure.ac (XE_EXPAND_VARIABLE): Set SHEBANG_PROGNAME. * configure: Regenerate. src/ChangeLog addition: 2008-01-20 Aidan Kehoe <kehoea@parhasard.net> * config.h.in: Add SHEBANG_PROGNAME. * emacs.c (main_1): If we've been called using SHEBANG_PROGNAME, rewrite our arguments to add a --script argument. Also, handle the --script argument by setting noninteractive and vanilla. * lread.c (Fload_internal): If the first two characters of a file are #!, replace them with ;! before they get to the Lisp reader. lisp/ChangeLog addition: 2008-01-20 Aidan Kehoe <kehoea@parhasard.net> * startup.el (command-line-do-script): New. (command-switch-alist): Use command-line-do-script. New argument, compatible with GNU; --script or -script says "treat the following argument as a file to load in batch mode". man/ChangeLog addition: 2008-01-20 Aidan Kehoe <kehoea@parhasard.net> * xemacs/cmdargs.texi (Command Switches): Describe --script, -script.
