[tw5] Re: How to launch batch scripts from TiddlyDesktop in linux?

[Dragon Cotterill]

Nah, using xgb-mime uninstall simply removes the actual software that 
changes the mime-types. Does nothing to remove the associations.
As you say, delete the entry from the mimeapps.list and it will stop the 
association (after a re-boot that is).

My warning about hackers is that the action can execute a script. Depending 
on how your script is written it may be possible to have very unintended 
consequences with allowing scripts to be run direct from a URL. The changes 
of this happening are extremely low though as the hacker will need to know 
what mime type and protocol you chose.

As to node.js, thats an whole 'nother kettle of fish.

[tw5] Re: How to launch batch scripts from TiddlyDesktop in linux?

[Dragon Cotterill]

Welcome to the wonderful world of Security Vulnerabilities and 
Work-arounds. Don't worry, this is my job.

OK, you need to register a new URL scheme handler. First create a Desktop 
Entry which specifies the mime-type. For example:

[Desktop Entry]
Type=Application
Name=TW Bash Script
Exec=twscript.sh %u
StartNotify=false
MimeType=x-scheme-handler/twscript;

Note that the %u passes the URL (eg. twscript://parameters%20here ) as a 
single parameter, according to the Desktop Entry 
Specification. https://specifications.freedesktop.org/desktop-entry-spec/latest/

Once you have created this Desktop Entry and installed it (put it in the 
local system applications directory ( ~/.local/share/applications/ or 
/usr/share/application/ ) then you must register the application with the 
MIME type (assuming you had named your Desktop Entry twscript.desktop

xdg-mime default twscript.desktop x-scheme-handler/twscript

Any script can then be added to the twscript.sh (make sure it's executable 
of course) and you can parse parameters just as any other script. The 
script should be placed anywhere in your executable path ~/.local/bin for 
example.

In the twscript.sh you'll have to add whatever parsing you need. You can't 
run separate scripts, but parameters are passed and can be checked and 
dealt with as appropriate.

Now, when an application finds the URL twscript:// it knows exactly what to 
do with it.

*WARNING! This will make your system vulnerable to anybody who knows the 
MIME type that you have used. They could create a script which would 
execute on your computer. I would advise against this, but there you go.*

Have fun,

Dragon.

The encrypted contents are "unlocked" when the password is supplied. As I 
understand it, this is done when the contents are displayed in the River, 
when on the screen. The original tiddler is still encrypted. So if you save 
the TW then the contents are saved in an encrypted format. (NB. I've not 
actually checked the various encryption plugins other than a cursory 
glance.)

Once the password has supplied then the whole thing is wide open anyway. 
Sneaky javascript added to any plugin can grab said contents and offload it 
to wherever necessary.

If you are looking for a fully encrypted and locked system, then I'm afraid 
TW is not it. You'd need proper signing of all the included contents to 
really make it secure, and even then you still couldn't guarantee it. At 
best I consider TW encryption as a way of preventing casual viewing of the 
entries. It is possible to create a "brute force" plugin which can sit and 
attack any given tiddler once loaded up in the browser. It might take a 
while, but if you feed it something like "rockyou" then you pretty much hit 
the majority of passwords.

I've pointed out before how incredibly easy it is to create Wikis from data 
sources. (Remember British Sheep?) And I've posted before about my Library 
which is a fully fledged system which hundreds of people use. It gets 
promoted in locations relevant to it's content. (Though I've yet to see it 
added to any TW site that lists/links to TWs). So don't get confused 
because you don't see the promotions.

If you want to read about the Hats of Henley then may I suggest that *you* 
create it?

[Dragon Cotterill]

OK, this drives me crazy. Pointing to a "Book" as a source for a TW is not 
a very good idea. TWs are made up of many, cross linked, individual 
entries. It's part and parcel of how a wiki works. If you want a prose 
entry then go to the book or write a document.

[tw5] Re: TW in Public -- "British Sheep Breeds" (#twClassic #animals #Britain)

That was just a simple web scrape and Macro to break everything up into

idea came from the suggests list, probably as a joke entry. Either way, I

It's not a working Wiki. Just use it as a basis for something else.

[tw] Re: Your invitation to the TiddlyWiki European Meetup 2018

[Dragon Cotterill]

Having been to these two meetups, I approach this with some scepticism.

Firstly the meetups are interesting in terms of putting names to faces, 
finding out how people are using TW, and generally being awed by how people 
are doing some seriously brilliant stuff. Elliot's Dyslexic work was 
nothing short of fantastic.

Secondly I am kind of disappointed in that the meetups didn't really 
achieve any kind of mile stone. No decisions or conclusions were made. 
Perhaps this is not the point of the meeting, but I feel that if we're 
going to get together then there should be some positive result for the 
community.

Many of the points we had put up on the Trello board to be discussed 
produced little result, other than as a talking point.

I am undecided at the moment as to whether it's worthwhile attending.

[tw] Re: Why is blockchain perfect for TW?

[Dragon Cotterill]

Blockchain is a solution desperately looking to solve problems.

OK, the idea of the blockchain is sound. It ensure that changes based on 
previous data is valid. There are two major drawbacks, one in the 
blockchain itself, and the second applicable to TW.

Firstly the big problem is the need for continuous calculations. This eats 
huge amounts of electricity just to be able to validate the transactions. 
The more transactions you apply, the more processing you have to do. This 
is inherently not scalable when it comes to enormous amounts of 
transactions. Bitcoin is just starting to feel these effect now, and once 
people realise the huge costs involved, the I reckon it will go into 
free-fall.

Secondly, and more applicable to TW, you cannot change any previous data.
TW is essentially a data storage, and some of that data is likely to 
change. Yes that change can be factored in to the chain, but sometimes data 
entered is wrong or temporary and needs amending.

No, blockchain is not suitable for TW.

[tw] Problem with savetiddlers

[Dragon Cotterill]

Been using the excellent "savetiddlers" plugin to handle my old TWC files. 
But often when I open the file afresh I get the error message:

savetiddlers has detected that another tiddlysaver called savetiddlers is 
> install. Currently only one saver is supported therefore - savetiddlers 
> will not activate


Bit of a pain, but there is a work-around I use.

Open up the TW and scroll to the very bottom. Delete the  that 
contains:


save it and you're good to go again... until the next time you close 
FireFox and reload your TW. Rinse and repeat.

Not sure if it's just me, or is there a bug inherent in the plugin when 
dealing with TWC?

That is very odd. That's the exact same plugin I use, also on FireFox, 
using TiddlyFox. Just to be sure, you're not using this from an http 
instance and saving to file? It will throw an error if you try that. Local 
file instance to file export should work though.

On my largest TWC (2185 tiddlers) I can export everything... but it throws 
an error "TypeError: this.source is null" at the very end. But it does 
actually do the export... after I have clicked the OK on the error.

I will admit, it's not the most robust of plugins, but it does seem to work 
sufficiently.

[tw] Re: [TWC] Export All Tiddlers

[Dragon Cotterill]

So my first concern would be, why does export not work?

In my experience it does work once the tiddlers are selected. Unless you 
have got some seriously messed up field that include quotes and apostrophes 
etc.

Does it produce any output? An error message?

OK, I've done exports with TWCs containing about 3,500 tiddlers, not the 
huge numbers you're quoting. But I've never had an issue with it.

Re: [tw] Query: Markup Parsers

[Dragon Cotterill]

This takes us into the realm of Yacc (Bison) and Lex for tokenising and 
parsing. Just a few Javascript versions and alternatives off hand:
https://www.npmjs.com/package/jscc-parser
http://zaach.github.com/jison/docs/
http://canna71.github.io/Jacob/

I'm sure there must be someway to sort out the tokenising of a standard 
Tiddler.

Hmmm, the last time I worked with Yacc/Lex was about 25 years ago. Guess 
I'm a little rusty on the subject these days.

Sorry, really not seeing it here. Well the example you posted above was 
straight out of the plugin. if you enter autosort thus:
|Name <> |Salary |Extension |Performance |File Size |Start date |h

It displays in the sorted order. Each time you re-load the tiddler (click 
off the recent timeline entry) in switched the sort order.

Is it because you may be adding autosort *before* the named column?

This appears to work perfectly for me. (Chrome, Firefox, Opera, Windows 8)

You sure you're not seeing remnants of your selections when you edit the 
Tiddler and save it? When you edit the entry it retains your selected 
sorting option from what you had before. It's only when you load it for the 
first time that the autosort kicks in.

I do however question the viability of making a roguelike for TW. Have you

I wonder if it's worth having an actual automatic level generator,

Having the level work done "in house" would mean that the game would be 
able to progress better as you could concentrate more of the actual 
gameplay rather than worrying about structural stuff.

As somebody who deals with security issues everyday, I'm going to say "No", 
and here's why.

The permissions you've set for you app requests unrestricted access to the 
user's Dropbox account. Which means that your system can access any file, 
in any directory. Whilst many people think that this only allows the user 
to trigger the interactions, selecting the necessary files as they wish, it 
does not restrict your API calls from perform additional requests at the 
same time. You may be honourable in your intentions and it's a good system, 
but there is the potential for abuse.

Now if the system was to only request the App Folder permission then this 
would be a lot better. The DB API system would prevent unwarranted 
intrusion and permit access to be restricted to files just within that 
folder.

Well yes, all my work is still in TWC.

In the normal export, the values for %0, %1 etc. change depending on which 
export option you selected. If you created your own export option, then it 
would be up to you to select the elements for export yourself.

I would suggest sticking to the methods which work as export and then 
process the resulting file into your XML. Exporting as .csv includes all 
the hidden custom fields on the tiddlers. It may not be elegant, but it'll 
get you a data format which you can then use outside of TW.

[tw] Re: TW5 How does TagglyTagging work here?

[Dragon Cotterill]

Import it with a simple .bat file to generate the s and then insert it 
into TW. It's taken about 3 years to get to it's current form.

But it's TagglyTagging which is at the heart of the system. I'd be really 
interested in your experiences with using TT inside of a TW5 setup.

Although the current TT plugins seem to do an excellent job of listing the 
sub-entries, they don't appear to do so well in displaying the hierarchy, 
and grouping options which the original TT did. Now it may be my limited 
understanding of the way TW5 works, but if it needs complicated editing to 
make it handle all the options, then it fails as a system which any "Joe 
Public" could use. The original TT didn't need any fancy settings or 
options. Clicking the display options did everything for you.

That's the kind of functionality that is needed to get people using it.

[tw] Re: TW5 How does TagglyTagging work here?

TagglyTagging is the reason I haven't yet migrated my main TW over from TWC 
to TW5. I make extensive use of TagglyTagging, especially with the grouping 
options as you can see: http://www.kizar.co.uk/TW/library.html

Having a decent TagglyTagging in TW5 would possibly persuade me to migrate. 
(Yes Migrate not Upgrade, TW5 still doesn't have as much functionality as 
TWC yet... but it's getting there fast.)

I've looked at the solutions provided by Tobias, Simon and Jed all come 
close to implementing the old classic TT system, but none match it for ease 
of use yet. But I do keep a hopeful eye on all solutions to this issue. 
Until then, I'll stick with TWC.

from there.

[tw] Re: Tiddlywiki for business

[Dragon Cotterill]

This is where I see the real downsides of using TW in a business situation.

Within a business the immediate necessity is to allow multiple users to 
access it at the same time. Obviously for reading this is not an issue. But 
for updating then this is where it's not so good.

Using Node to act as server-side to allow multiple users still doesn't 
solve these issues for TW usage. Because there is no communication 
mechanism to notify users that the page they are looking at has been 
modified. With software such as Confluence 
( https://www.atlassian.com/software/confluence ) this has all been 
resolved. TWederation is possibly one way around this limitation, but it's 
not quite there yet.

But for a single user, then there is nothing else which comes close to the 
flexibility of TW in terms of cost.

Yes.. "Unexpected".

Actually the way week numbers are calculated around the world 
changes. https://en.wikipedia.org/wiki/Week#Week_numbering
ISO8601 starts the week on a Monday. America starts it on a Sunday. This 
throws spanners in the works depending on Time Zones, Daylight Savings etc. 
Considering North America went through it's daylight savings shift, this 
may have had an impact.

I would point out, that in the ToDo section of ArchivePlugin it

This would suggest that it hasn't yet been implemented.

[tw] Re: [TWC] How to use ArchivePlugin Online

[Dragon Cotterill]

I use TWC a lot. Though I do not use that ArchivePlugin. Instead I used 
SharedTiddlersPlugin from http://yakovl.bplaced.net/TW/STP/STP.html

In this way I can export out any unneeded tiddlers and import them as 
needed when opening a tiddler, or, by adding them in the "IncludeList" 
tiddler, at load-time. It is incredably easy to use, and judging by the 
ArchivePlugin documentation, probably better suited to your needs.

[tw] Re: Searchable fields when using _Canonical_uri ?

[Dragon Cotterill]

This is one of my biggest problems, with one of my TWs. My Doc Library 
( https://dl.dropboxusercontent.com/u/1207193/library.html ) has a lot (and 
I do mean a LOT) of PDFs in it. Most of the entries point to a document of 
one sort or another.

For local access I have not found any program which is capable of indexing 
the documents in a directory and making that index accessible. This is your 
issue Mark. Attached or linked documents are not part of the TW structure. 
Including the content of said document inside TW essentially doubles the 
storage space and inflates the size of the TW. Which to my mind makes it an 
unworkable solution.


But this Dropbox removal of opening HTML files (which interestingly enough, 
I have not received notification of) may force my hand into moving the 
whole system into Domino (my web server of preference) where all of the 
content would immediately become searchable.

I have been toying with the idea now of pushing TW into a Domino platform, 
as this would solve a number of issues such as multi-user editing, 
security/authentication, advanced searching etc. Looks like I might have to 
implement this sooner rather than later.

Yep. Thats certainly a very valid reason for doing this and I applaud that.

But the opening post was about how to present this to the world. Presenting

The core function of TW is to be a Wiki. I think we need a functionality

I'm at a loss to figure out.

I've been following along with TWederation, and even took part in some of 
the demo at the meetup. I fully understand the "How" it works and "What" it 
does.

What I completely fail to see is the "Why". More specifically I fail to see 
where such a system would actually provide a working use outside of 
contrived setups just to prove the techniques.

TWs are not normally static. They grow and are used for many different 
things. Cross loading the entries into another TW, the entry then becomes a 
static value. Forever embedded. If the original is updated, the TWederated 
value still remains at the old value. Good for historical reasons. Bad for 
interaction.

What I would like to see as a main "selling" point, is an actual real use 
case which can be utilised by general users. A "discussion" forum is not 
what I would consider a valid use case. It needs to be something specific 
to the core of what a TiddlyWiki is.

[tw] Re: The proper way to keep a TiddlyWiki organized

[Dragon Cotterill]

The "proper" way to organise your TWs is... whatever works for you.

There is no right or wrong way. It's whatever works for you. If your 
reading list needs to be separate tiddlers for each book for some, and a 
big long list for others then you can mix and match as you see fit.

I have a whole slew of TWs; some are full blown TWs with 1,000+ entries ( 
https://dl.dropboxusercontent.com/u/1207193/library.html ), others are 
small with just a few thoughts in them. And some have even been reduced to 
PureStore formats and are included in other TWs.
My Food and Recipe TW is stored separately from my Video index. However if 
you're in the Food one and you click the right link, then it imports all 
the video tiddlers related to food TV programmes into the Food TW, with all 
the appropriate embedded VLC objects to play the recipe.

Your reading list may cross into your gaming list at some point. Separate 
or together doesn't make much difference really.

[tw] Re: [TW5] Editor Toolbar - Adding a browse for files button ( [ext[...]] )

[Dragon Cotterill]

Hi Bo,

On Monday, 25 July 2016 09:18:15 UTC+1, The Bo wrote:
>
> Any idea or is there already such a plugin?

As Jeremy stated, it's almost impossible to get the details to external 
files from inside TW due to the security restrictions of the Browsers.

One of my TW's makes extensive use of external files (.PDFs and images) and 
the only way I could get them integrated was with external batch files.

This is one of my import routines:
@echo off
cd Unsorted
for /f "Tokens=*" %%f in ('dir /l/b/a-d') do (rename "%%f" "%%f")
cd ..

FOR %%A in (Unsorted/*.pdf) DO (
echo ^ >> entries.div
echo ^^|!Name: ^|%%~nA ^| >> entries.div
echo ^|!Author: ^| ^| >> entries.div
echo ^|!Date: ^| ^| >> entries.div
echo [img[./Images/Book.png][./Documents/%%A]] >> entries.div
echo ^^ >> entries.div
)

It is designed for TWC and has a specific layout, but it may suit your 
needs. But what it does is first switch everything in the "Unsorted" 
sub-directory into lowercase (this prevents loads of error where it tries 
to wikify the names of the .PDFs that are imported) before building a file 
with all the names of the PDFs as tiddler titles. The resulting file 
(entries.div) is then placed inside the TW file. When I go through and edit 
all the "Unsorted" tagged entries, TW handles the tidying up of the actual 
tiddlers.

Yes indeed. I see you come from the same thoughts as me on this.


I'm not saying that people should use the GUID as a matter of course. The 
Title of the Tiddler would always be the main linking point. But for 
TWederated Tiddlers there will be issues where this will fail. Yes we could 
keep using the Title and have some other mechanism in place, so clicking a 
link to two imported tiddlers with the same name either opens both, or 
prompts you for which one you meant. But responses to tiddlers would get 
messy.


There can be no denying that what Mat and Jeb have done with TWederation is 
a great idea and with the work they did over the weekend it proved it has a 
permanent home in the TW realm, but unless steps are taken at this early 
stage to address things like this it could open up a world of problems.

[tw] Random Thoughts about the new version of TW.

[Dragon Cotterill]

This is just a quick list of some of the thoughts following on from 
conversations with Mat and Mario at the Pub after the TWEU Meetup. As with 
any Pub conversations it is likely that most of these ideas will fall by 
the wayside, but some of the ideas have got me thinking and it's worth 
getting them logged whilst they are fresh in my mind.

There can be no doubt that TW is a really great concept. But now that we're 
joining them together (by TWederation) we are going to run into some 
seriously big road blocks if we're not careful. For example how do we 
handle the importing of Tiddlers with the same Title?
I feel that it is very disingenuous to force users to create shared 
Tiddlers with different names. At the moment we are doing this by adding 
the creators name to the end of the Tiddler's Title. This I feel is a big 
mistake. The naming of the Tiddlers should NOT be enforced like this. The 
creator should be free to name them however they want. But of course this 
throws a spanner in the works when names clash.

What we need is a unique way of identifying the Tiddler that is visible to 
TW, but not necessarily to the users. Pretty much every database system has 
a Key or a Unique ID and I think we need the same.
Now I know that Jeremy would say that your should be able to link to the 
Tiddler via the Title, and I fully agree. In any given TW the Title is 
unique (Shadows not withstanding). So that is the link you would use when 
linking to them in a given instance. But when a TW is federated, with the 
same name, which "New Tiddler" do you mean? Because they should all be 
available.

I propose that each TW should have a UID. It should be comprised of the 
hash of the URL of the TW, and the hash of the date/time when it was 
created. And that ID should stay with it for the life of it's existence. 
Even if it's federated into a new TW, then the ID stays. The only time it 
should gain a new ID is if it was copied, the copy getting a new UID.

Now when it comes to TWederation, the structure is clear. HASH1 is the 
parent. HASH2, HASH3 are children of the parent, HASH4 is the child of 
HASH3. Using this it is very clear how the individual tiddlers should be 
displayed, now matter what the actual content of them. If a Tiddler is a 
reply, then it has a parent. If no parent, it's a top level entry.
Tiddlers change. At present if a federated tiddler is changed, that change 
is not propagated (or have misunderstood the workings of TWederation? 
Mat?). If a parent tiddler is deleted, what becomes of the orphans? Yes, 
there is still much to discuss on this.


Now one of the other thoughts I had was in the concept of data Tiddlers. I 
know Mario wants to see all the data of any given Tiddler, but that's a 
different matter. :) You should be able to have data WITHOUT the concept of 
how it should be displayed, but use another Tiddler as the actual layout. 
We have the ViewTemplate tiddler, but if you break that down to a smaller 
level you can start to build up the Tiddlers to produce stronger concepts.
At present TW is geared around Text components. Title, Text and Tags as 
core values (yes I suppose created, modified and change count are other 
values too). TW Classic has the Data Plugin ( 
http://tiddlywiki.abego-software.de/#DataTiddlerPlugin ) which kind of uses 
this concept. TW5 allows you to add further fields relatively easily. But 
what if you took it further?
By opening up TW to the concept of data you could really build up 
applications. For example a remote weather station server simply outputs a 
raw tiddler stream of weather data. You can TWederate that data straight in 
to get an idea of rainfall. Others could get the exact same data but be 
more concerned with wind speed and direction. Or both. Or temperature.
You would write a macro which would take all of the data and display it 
using the layout of another Tiddler. An iteration over that list would give 
us a simple table. Another version would format it for feeding into a chart 
(HighCharts anyone?) Or a data connector that changes it in some way to 
feed into other components (temperature delta over time? Temp vs Rain?)
This would give us an extremely powerful, dashboard like configuration.



As I said, these are just some random thoughts, typed up on a train journey 
back to London after the TWEU Meetup. They need refining in so many ways, 
but I feel that they may have some merits.

Discuss...

This to me sound more like the old Groove Networks database system was 
based. I feel that you really need to take a look at the Groove 
architecture as it does have possible implications which parallels what you 
are trying to achieve here.

I kind of achieved something similar using TWC, when I created "worker" 
wikis. Each worker had their own TWC installation, and I used the 
SyncFileTiddlerPlugin ( 
http://tiddlywiki.abego-software.de/#SyncFileTiddlerPlugin ) to export a 
single tiddler which carried the actual work. This was replicated around 
via DropBox into the central wiki (mine) where I could see the changes and 
re-allocate the work out the the workers. It wasn't a true cross 
installation setup as each worker only saw their own stuff.

In fact you could exact mimic such a setup with the TWC 
SharedTiddlersPlugin ( 
http://yakovl.bplaced.net/TW/STP/STP.html#SharedTiddlersPluginInfo ) simply 
by "including" the shared wikis of the other users in the network.

But what you're trying to achieve goes far beyond this kind of system and I 
wish you well in it's implementation.

[tw] Re: TiddlyWiki European Meetup 2016

[Dragon Cotterill]

I am curious as to what the meetup will consist of. Having done various 
Hackathon's in the past (most notably the London Dropbox Hackathon) I am 
wondering if it would be anything like that. Or will it more more of a 
discussion about the possibilities of TW?

Unfortunately I can only attend on the Saturday. But I would like to know 
if there is anything I can prepare before hand.

Regards,

Dragon.
