Subject: A protype of .prompt support in fiddle but its utility there is in doubt because... 
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=9d950aa13b7ea5d0a3ab5ec4ccd9a1f6fcf66c46;p=thirdparty%2Fsqlite.git

A protype of .prompt support in fiddle but its utility there is in doubt because .open does not work there, so there's very little dynamic info worth showing in a prompt. Also, ANSI colorization can't work there, nor can we colorize the prompts using HTML because of limitations in jquery.terminal.
