When I turn off lazy-shot and use the default font-lock, my test case gets correctly fontified on revert-buffer. This always failed with lazy-shot. Ray

Re: patch very preliminary support for /dev/pts/ 25 years, 4 months

Neal D. Becker

Just try M-x shell, for example, and see if it works OK. From within the shell mode, type 'tty' to see what pty it's using. If it doesn't work, it'll probably complain about not being able to get a pty or something like that.

insert-file-contents is broken 25 years, 4 months

SL Baur

[The replace flag is used by `revert-buffer' and its not working is what Karl found wrt revert-buffer not working.] Does the following comment apply to XEmacsen with file coding and no Mule? `insert-file-contents' is a compiled Lisp function -- loaded from "/usr/local/devel/miho-21.1-optimized/lisp/code-files.elc" (insert-file-contents FILENAME &optional VISIT BEG END REPLACE) ... NOTE: When Mule support is enabled, the REPLACE argument is currently ignored. ... A quick test is xemacs -vanilla M-: (insert-file-contents "/etc/hosts" nil nil nil t) The contents of *scratch* are either replaced by the specified file or appended to. I've tested both 21.1 and 21.2 with Mule, and in 21.1 the comment is clearly wrong. The replace flag works in Mule. It doesn't in 21.2. Who was the last person to be diddling with `insert-file-contents'?

Update: I see this only in 21.2, not 21.1. The code to `revert-buffer' hasn't changed so I presume the difference must be a side effect of some other change. Ugh.
