Dear Bug Team! Indenting source code with cc-mode never works exactly how I'd like. cc-mode is quite configurable, so I'm trying to tweak it, but my fixes usually break some case which previously worked OK, and I don't even notice - clearly I need regression testing. I was thinking of keeping a collection of source files and running XEmacs on them in batch mode, with a driver like === test.el === (find-file "Hello.java") (indent-region (point-min) (point-max) nil) (save-buffer) === end test.el === (it would probably be better to have the name of the source file on the command line, but that's a different complication) plus some higher-level script checking that the re-indented files stayed the same. This setup won't work on Windows, because opening the Java file loads JDE (as it should), and JDE prints quite a few messages about its progress. When I run xemacs -batch -e -l test.el from a cmd window, I get a *different* one with messages like === xemacs -batch -e -l test.el === Bootstrapping objects... Bootstrapping objects...done Loading customization dependencies... Loading customization dependencies...done jde-java-font-lock: building names cache... jde-java-font-lock: building names cache...empty Setting JDE variables to startup values... Indenting region... Indenting region... done (No changes need to be saved) === end xemacs -batch -e -l test.el === and then an error dialog: Messages outputted. XEmacs is exiting. And I have to press a button to get any further... I think batch mode should not show any dialogs, ever. ================================================================ System Info to help track down your bug: --------------------------------------- OS version: Microsoft Windows 2000 [Version 5.00.2195] OS: Windows_NT XEmacs 21.4.6 \"Common Lisp (Windows [1])\" configured for `i586-pc-win32'.
