TiddlyWiki on Chrome / Ubuntu 64-bit

[Grmble]

Hello everybody,

it bugged me that TiddlyWiki did not work for me under Chrome, so
today I started digging around and here is what I came up with.

There are 2 problems:

* The "default" icedtea-plugin does not work with TiddlySaver.jar -
it claims not being able to decode UTF-8
* By default, the TiddlySaver applet is not "shown" under chrome

Here is what I did to solve them:

* I installed the latest SUN/Oracle JDK. Sadly these are not in the
ubuntu apt-repositories anymore but I did not find a usable java
plugin in the OpenJDK packages I have installed. The manual
installation of the SUN/Oracle JDK is explained here:
http://sites.google.com/site/easylinuxtipsproject/java
* I hacked the TiddlyWiki file in vim so the applet is displayed under
Chrome

+var useJavaSaver = (config.browser.isSafari || config.browser.isOpera
|| config.browser.isChrome) &&
(document.location.toString().substr(0,4) != "http");

I did not do much testing yet, but so far everything I use seems to
work except LessBackupsPlugin. Which is fair since it uses Firefox/IE
specific code to do it's job.

I've played around with this some more and it isn't even necessary to
add the "isChrome" thing - the user agent string contains
"applewebkit", so Chrome is considered a Safari-variant, and the
Applet is displayed anyway.

So installing a non-IcedTea java plugin is all it takes for Chrome
under 64-bit Ubuntu.

Cheers,

Hi Juergen,
Did you test

Hi Mario,

No, but it doesn't need any special operations so I don't see why it
would not work. Thanks for the heads up!

I just spent an evening getting LessBackupsPlugin to work. I added
file existence check / file modification time operations to the
TiddlySaver applet and used those in the plugin. Not as easy to deploy
as BackupOptionsPlugin, but with Dropbox I really like
LessBackupsPlugin with the per minute and seconds backup removed.

Kind regards,
Juergen

Could you please share these TiddlySaver mods? I'd love to see them
added to the standard distro, as I have several plugins that could
make use of them. It would also be great if you could add a "get
directory list" function as well.

thanks,

Hi Juergen,
It would be nice to have the "modified" LessBackupsPlugin too :)

I am a bit surprised about the interest on this, I thought this would
have a really small target audience ...

I pushed the TiddlySaver changes to my github fork. The jar is
signed, but I used a self generated certificate. Probably not good
enough for the general public.

For illustration purposes, here is how you use the new methods:
https://github.com/grmble/MPTW/commit/02854fdfa1cca3aa3cd1a86d04030bae53f09790

The "get directory list" function should not be a problem, but it's
past my bed time, mañana ;)

Also this didn't get much testing, but it seems to work for me on 1
computer ...

Good night.

Just to let everyone know, I've been in touch with BidiX, who has
kindly prepared a new revision of TiddlySaver.jar based on Grmble's
patches:

https://github.com/TiddlyWiki/tiddlywiki/pull/79

Thanks everyone for your help,

Best wishes

Jeremy

I'll spend some time testing this - though probably not much over the
Christmas period :-)

It would be good if other could also do some testing.

Note also that grmble hasn't finished working on this yet, see:
https://github.com/TiddlyWiki/tiddlywiki/issues/78#issuecomment-3254138
so we will need to do another jar sometime in the future when he has finished.
