Announcing Math Equation upgrade to TWT-Notes

[Morris Gray]

There have been some cosmetic changes more soothing colours and a
general tidying up and bug fixing.

A major addition is that you can now keep notes if you use math
equations. TWT-Notes has combined with CodeCogs to bring equation
rendering to TiddlyWiki.

Whenever a tiddler is in edit mode, clicking on 'equation' in the
QuickEditToolbar will launch an equation editor where you can
construct math equations. Once you are done with the equation simply
click the "Copy to Document" in the Equation Editor and it will insert
the equation into the tiddler at the cursor position.

This is a major achievement for simple math equation generation. Now
you can have quality equations for school, work or play.

Someone mentioned they didn't like two search boxes so the one in the
sidebar has been replaced with a Live update notification. It just
notifies you that TWT-Notes has been updated and by clicking on it
shows a popup with the latest news and changes. It works even if TWT-
Notes is on your local disk. (you must be online of course.)

Some say to kill a book from selling you need only put one equation in
it. But there are a lot of people who do need to use equations and
now TWT-Notes can help them. It's so easy anyone can do it.

Give it a try so you can remember to mention it if anyone asks how to
do equations in a TiddlyWiki without loading it down with extras. I
will make a plugin available soon.

Morris, this is an interesting approach to have LaTex features in TW
easily and more or less TW code indepently. Since the math equations
are rendered as images and stored at a CodeCogs server, the question
about their "life time" arise: how long are this images available on
the CodeCogs site.

One possible solution to this: downloading the images from the
CodeCogs site, storing at the own file/web space and changing the
image URL accordingly manually for all equations.
To have this as automatism feature incorporated in your implemention
would be a great ease.
Cheers Michael

Hi Morris

I begun, or I'll do something similar ("plugin" - or actually JsMath
extension). Oh no..., looking at my first tiddlers creation date -
19.8.2007, I wanna cry. That is the result of the lack of free time
(and still waiting for Eric's developer's guide). I had much more in
mind than this. I have enough notes (defined "usecases"), what should
it do. Not just copy to document, write/edit LateX in view mode,
predefined and user defined menus (switching between them), last n-
used, history (showing forward/backward steps)... The primary target
was just to avoid edit mode in TW, because it becomes too difficult to
add, delete something if you already wrote many lines in LateX. I
know, someone like Eric is able to do it in 1h..ok maybe in 1 day or
2, but me :(.

I think CodeCodes or some of it's variations will be around for a long
time. It is free open source code and many people are already using
it and have modified in their own way.

See http://www.yourequations.com it's powered by CodeCogs as well as
others

The images are not stored as much as they are generated when you send
the code there and are returned as images. To prove it there is
nothing to prevent you from generating totally unrealistic
equations:-)

Of course for life-time archiving you can just download the images to
your own files and store them anywhere you wish.

By the way I have just generated an empty TiddlyWiki powered by
CodeCogs it's got a few enhancements like tabs (TiddlersBarPlugin),
QuickeditPlugin my own Search results enhancement, and the ability to
publish tiddlers as HTML pages. But it's basically empty and ready to
name and use.

Go to http://twequation.tiddlyspot.com/ click download in the sidebar
and try it.
