Only if you understand javascript as opening the source for
blank.html shows 100s of lines of the stuff
The relevant lines so far as I can tell (me knows nuttin about any
sort of code) - apologies in advance for bad wrapping
// Browser detection... In a very few places, there's nothing else
for it but to // know what browser we're using.
config.userAgent = navigator.userAgent.toLowerCase();
config.browser = {
isIE: config.userAgent.indexOf("msie") != -1 &&
config.userAgent.indexOf("opera") == -1, ieVersion: /MSIE
(\d.\d)/i.exec(config.userAgent), // config.browser.ieVersion[1], if
it exists, will be the IE version string, eg "6.0" isSafari:
config.userAgent.indexOf("applewebkit") != -1, isBadSafari: !((new
RegExp("[\u0150\u0170]","g")).test("\u0150")),
firefoxDate: /Gecko\/(\d{8})/i.exec(config.userAgent), //
config.browser.firefoxDate[1], if it exists, will be Firefox release
date as "YYYYMMDD" isOpera: config.userAgent.indexOf("opera") != -1,
isLinux: config.userAgent.indexOf("linux") != -1, isUnix:
config.userAgent.indexOf("x11") != -1, isMac:
config.userAgent.indexOf("mac") != -1, isWindows:
config.userAgent.indexOf("win") != -1 };
and later on
// Whether to use the JavaSaver applet
var useJavaSaver = config.browser.isSafari || config.browser.isOpera;
I presume the JavaSaver applet is the TiddlySaver.jar file I was
told to put in the same directory as the tiddlywiki or
whatever.html is stored.
The problem is still how to get opera to use this jar file by means
of the .java.policy file. I have tried various permutations of the
syntax but still cannot get opera to save an alteration.
currently my .java.policy looks like this:
grant codeBase "
file://localhost/home/jayell/Notes/*"
{
permission java.io.FilePermission "home/jayell/}Notes/*",
"read,write";
};
