[tw] Re: How to fold/unfold filter tipped lists by date

[Tobias Beer]

Hi Kolya,

That's a neat site. I like those gifs!

On the other hand, I find trees pretty annoying.

What would you think of a kind of filter? The first row would provide
year-buttons, when - if clicked - only those results of that year are
being displayed. The second row would be an equivalent month filter.
One more button to reset the lot and you're set.

The buttons could actually have two functions...
1) single select
2) range select

What do you think? Other than that, you could try and implement
something like this...
http://bassistance.de/jquery-plugins/jquery-plugin-treeview

...provided that you have a macro that outputs the lists in the
required format and loaded
* jquery.treeview.min.js (tagged systemConfig)
* jquery.treeview.css (included by your StyleSheet)

...into TiddlyWiki.

Cheers, Tobias.

[tw] Re: User roles

[Tobias Beer]

Hi whatever,

Some answers...
1) Is the EvalifyPlugin required?
No, not unless you want to display the user role on TiddlySpace as I
did. In a Non-TiddlySpace-TiddlyWiki you can use the tiddler macro
like so...
Tiddler:GetRole
<>/%
!OUT
$1
!END%/

2) Because I keep getting errors.
Where, when, which?

3)  Also, I'm not clear on how to assign roles.
Simply put the user-names into the corresponding sections of your
SimpleRolesConfig tiddler.

4) Do I need to use something like <>? And
where do I put that?
Of course not, or do you want your users to choose their own role?
Again, you assign roles to users in SimpleRolesConfig.

5) And how do I define, to which tiddlers a User has access as opposed
to an Admin or PowerUser?
You would have to use conditional templating as in the example. You
could also define different restrictions for search with
YourSearchPlugin or GotoPlugin... and then include those
conditionally.

As an example using HideWhenPlugin...







The same way you could hide the entire tiddler content.

6) Do I need to create tiddlers with usernames?
Not when it comes to roles, no.

You could, however, tag tiddlers with a role - like "Admin" - and then
use a conditional statement to check if the role is assigned to the
current tiddler AND the current user.

Cheers, Tobias.

Hi Jon,

I'll create a space for it...

How would you want that table to look?
The data comes in multiple dimensions:
- the primary value
- the target or comparative value
- the scales (bad, fair, good, very good)

Something like this?
|primary|value|
|comparative|value|
|scales|level_1,level_2,...,level_n|

What about the label option?

In general, what is the benefit of such a table, since it would quite
significantly increase the code?

[tw] How to fold/unfold filter tipped lists by date

[Kolya33]

I'm using filter-tipped lists on my site to present content types by
tags, eg all tiddlers containing a music-video, ordered by creation
date. (see: http://www.schwarzsilber.de/#[[Music%20Videos]])

Now this list is bound to get very long and I would like to see it
fold and indented by years and months. Like this:

- 2011
  - February
 tiddler
  + January
+ 2010
+ 2009

So you would click on a year node to unfold the months, then a month
to unfold the tiddlers from that period, then the tiddler you actually
want to open.
Preferably it emulate the windows explorer behaviour of closing sister
nodes when opening a node but that's not too important.

Maybe  you can point me in the direction of a plugin, or better yet:
How to integrate this function with the filter-tipped lists I have?

Tiddlywiki's are very flexible and very expandablewith the plugins
you can create endless! variety's of applications for different
purposes.
The basic (empty.html) tiddlywiki is a primary platform, plugins give
it more weight (someone else might not need the imagesize
pluginand some other plugins might be less useful for your
purpose).

OK, now I've been using

so that I
a) have the file name in quotes so spaces don't matter
b) can specify resizing.

It seems spaces aren't an issue

[img[path to images directory/name of the sample copy.png]]

works OK.

No,mass renaming across a number of machines is not an alternative.

As for resizing, when I google I only find that needs a specific new
tiddler. http://www.tiddlytools.com/#ImageSizePlugin

 Isn't is built in somehow?  I'm surprised.

Here's all that's necessary for that:

I'm uncomfortable maintaining such a space myself though, as I don't

[tw] Re: TiddlySpace, Security and Computer Macro Parameters

[Tobias Beer]

Hi Jeremy,

Since parameter evaluation seems a client-side issue, here's what I
suggest (the official TiddlySpace crew to provide) for now...

Create a space called EvaluatedParameters which one can include to
ones own space, which reactivates parameter evaluation and thus the
use of (mostly Eric's) transclusions.

I think this should be somewhat easy to implement and allows users to
get back this much desired functionality (at their own risk). Before
that, however, you might want to make sure that including another
space will not auto-include this or any other subspaces.

Cheers, Tobias.

[tw] Problems formatting images

[Anton.Aylward]

This is in two parts ...

All the examples I see at twhelp.tiddlyspot.com of inserting images make
use of external URLS.

I'm trying to use a local file.
My problem is in two parts.

The tiddly file and the images are on a USB stick.
The image in in a subdirectory relative to the tiddly file.
This is for 'portability'.   I'm concerned.
Do I begin

   file:///./path to file.png


The second is that there are spaces in the path

"Path To Directory/Name Of The File.png"

How is that to be expressed?  This has to be portable between Linux and
Windows.  I'm concerned that escaped spaces don't seem to work, and
quoting the whole filename doesn't seem to work either.

PowerUsers can access additional tiddlers and Admin can access all
tiddlers. Obviously any tiddly-savy person can get around the
restrictions, but my users aren't tiddly-savy. As Eric put it in his
TiddlerPasswordPlugin, I want the roles to be "latches", not "locks",
the intent is to prevent accidental opening. Is this possible?

I guess what you want is not a return statement on it's own but
instead a...

Other than that, you could put the entire script in another tiddler

The idea that the progress bar list the next next is also really cool!
Didn't thought of that. Also, Ithought it was finished, and still so much
work to do I really underestimated it.

[tw] unknown error in script

[Seba]

Hi,

I have problem which I can't really determine:(

I've created a tool for a game which helps keep track of things to do
and so on.
I want to share it with anyone who would like to use it as an
unofficial addon to the game. For that purpose I've set it up in a way
all one needs to do is point and click without ever having to enter
the edit mode.

However, there is a problem:)

For creating a new tiddler from a button inside a tiddler which adds
the title of source tiddler as a tag I have this:


var alwaysTag="quest";
var tid=story.findContainingTiddler(place);
tid=tid?tid.getAttribute('tiddler'):'';
var charTag=(tid).toLowerCase();
var p=prompt("Enter the quest name","");
//return
var title=(p);
var tags=(alwaysTag+" "+charTag);
store.saveTiddler(
title,
title,
store.getTiddlerText('questTemplate'),
config.options.txtUserName,
new Date(),
tags);
story.displayTiddler(null,title);

-
Please look at the //return if I remove the // the button doesn't
work. However I need the return function so that user can abort the
creation of a new tiddler without affecting the entire tiddly.

Please have a look at the tool:

http://users.volja.net/adonis25/estiah.html

Go to Kuharcek->New quest or just select edit while in Kuharcek.

I hope this wasn't to confusing.

thx

regards,
seba

This could be a neat little plugin to go along with statistics or even

I also took out that one jQuery statement as it really wasn't

Re: [tw] Re: TiddlySpace, Security and Computer Macro Parameters

[Jeremy Ruston]

That's a good insight: what we're dealing with here is best treated as
a new kind of plugin, one that is evaluated at the point of reference,
rather than at startup. I really like that idea.

I'd think of it as a tiddler tagged "systemScript" that contains
javascript that is executed when the tiddler is referenced through
<> (or perhaps some new syntax like [[[tiddler
title]]]). The JavaScript code would be invoked with the roughly same
context as macro handlers, plus the with: parameters on the
<> macro.

> 1) But "server side".

You're meaning that the verification for safety of systemScript
tiddlers would happen on the server? If so, I would agree.

Changing the implementation of evaluated parameters doesn't add
security on it's own, but it is one of the necessary components for us
to implement safe filtering on space inclusions in the future. Tobias'
quick eval hack is a systemConfig tiddler and so would be filtered out
of a safe inclusion. That's the whole point: forcing javascript code
up out of invisible {{blocks}} and into manageable plugins.

The motivation for bringing up the change early is to minimise
disruption; as the service grows, more spaces would be affected by any
change we make in the future.

That is also one of my motivations in being interested in the hashing
mechanism being added to the server.

I was thinking of the hashing more for blacklisting plugins that have
known vulnerabilities. For example, a trusted member of the community
may write a plugin that unwittingly parses and processes some piece of
user input as HTML. Then, a mischievous person discovers that
vulnerability, and publishes a specially crafted tiddler that if
included in spaces that include the original plugin would cause data
loss. Note that the mischievous person there is only publishing "safe"
content, but is exploiting a flaw in trusted code. In that situation a
blacklist would be a good way to pick up people who have copied and
pasted the plugin into their spaces. I'm sure there are other measures
that need looking at too, but this fingerprinting seems pretty
fundamental.

In terms of whitelisting, I was thinking of letting users have a list
of spaces they trust, and optionally to also trust the spaces that
those spaces trust. Everyone would start by trusting tiddlyspace,
which would trust the established developers. As a user I would want
to know how many other people trust or actively mistrust a space.

As you say, the way that we establish all this deserves deep
discusion. It's possible that UnaMesa might have a role in this,
maintaining the register of the highest grade of trust for people who
have, say, been through a legal notarisation process so that the
community can have some confidence in who they are.

You mean the whitelist filter combined with having the tiddler tagged
systemScript because it contains JavaScript?

Agreed, as above.

[tw] Re: Having a hard time with my progressbar layout...

[Tobias Beer]

I have added some more information to the example tiddler as for
parameters and StyleSheet...

Thinking of some computed progress based on a todo-list it might be
cool if one could define a function that retrieves the next todo when
clicked on the progressbar... that however is just one use-case for a
progress bar. Possibly named parameters also work better. The first
two may remain fixed but at least showVal and showPct should be named
parameters... that way one could more easily add parameters to the
params array later.

Cheers, Tobias.

[tw] Re: TiddlySpace, Security and Computer Macro Parameters

[PMario]

I also think, that erics transclusions should be treated like plugins.
And I also think, this can be achieved.
1) But "server side".

2) As you can see that  "not executing" evaluated parameters
clientside doesn't add any security to tiddlyspace. As Tobias has
shown with his quick eval hack.


Some thoughts about 1)
Hash the content, and compare against a "plugin whitelist", when the
tiddler is saved.
If it doesn't pass the test, it can be _private_ only.
So I can use and test it until it passes the test.

A private malicious tiddler can only effect space members. But as a
owner of a space I'd only make someone a member, if I trust her or
him. The server could tag a private tiddler "test not passed". So
members can easily find them and togehter make them pass the "approved
for public use" tests.

There is the question. How to get a "plugin white listed"
I think this should be discussed at TiddlyWeb or Dev group.


There has been some dicussion about the target group, that uses/should
use TiddlySpace.

a) As a default user (80%) I'd want to write text.
Make it public.
Done.

b) As an advanced user (15%) I'd want to write something like:
<> or
<>
I think some server side white list filter can see that this should be
allowed.
Done.

c) As a programmer (5%) I should be able to write code, that can be
"approved for public use".
And how to get "white listed" should imho be discussed at TiddlyWeb or
TiddlyWikiDev group

d) may be there is a better solution for b) so it can be added to a)
