Hi Måns... I guess, above all, slices allow you to put any context around them, without influencing your ability to list them. So you're not constrained to a well-formed hr-separated list. Tobias.

I guess, above all, slices allow you to put any context around them, without influencing your ability to list them. So you're not constrained to a well-formed hr-separated list. Slices *are* very useful. However, there are some limitations that you should be aware of: You need to know what the slice names are in order to access the values, and each slice has to have a unique name within the tiddler. In addition, slices cannot contain multiple lines of text, nor can they use the | symbol (assuming the slices are defined using TW table format). In contrast, HR-separated lists are simple sequences of *unnamed* items, and can contain multiple lines consisting of any sequence of characters except, of course, for a line containing just an HR (), as this would signal the end of one item and the start of the next. -e --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups TiddlyWiki group.

I tried to implement these line in the first script like this:
script
var out=;
var txt=store.getTiddlerText($1,);
var items=txt.split(\n\n); {
if (!items[1]) items=txt.split(\n); // start a new row
out += |+items[i]; // add item to row
}
out += |\n; // end last row
return out;
/script
Well, it would help if you hadn't *removed* the part of the code that
actually *loops* over the entire list of items. Go back to my first
post in this thread that contained the complete script. You should
just replace the original line that fetches the 'items' array with the
3 lines that fetches it using either format, and leave the for (...)
loop statement as-is, so that each retrieved item can be processed and
added to the output.

Eric
Alternatively, here's some general-purpose code that first tries to
split the text on the HR separator... and if only one item results
(i.e., there are *no* HR separators in the text), then tries splitting
on just a simple newline, allowing either format to be used, as
appropriate:
var txt=store.getTiddlerText($1,);
var items=txt.split(\n\n);
if (!items[1]) items=txt.split(\n);
I tried to implement these line in the first script like this:
script
var out=;
var txt=store.getTiddlerText($1,);
var items=txt.split(\n\n); {
if (!items[1]) items=txt.split(\n); // start a new row
out += |+items[i]; // add item to row
}
out += |\n; // end last row
return out;
/script
But I only get the first line/first cell of the table.
What would the working script look like?

[tw] Re: How to turn a hr-seperated list into a table with several columns?
Eric - is it somehow possible to make the script work on a
lineseperated list produced by a fET?
This would give infinite possibilites for producing tables with data
fetched from tiddlers - and sorted by the fET..
I know how to make a single multicolumned table in a fET already - but
it would add the ability to make overflow on *long* tables from very
simple fETs -
If a fET could actually write a real textlist - then this script
could format the list to a table..
Am I dreaming?

[tw] Re: How to turn a hr-seperated list into a table with several columns?
First question, I m not familiar with the term hr-seperated list.. Do you mean a list which has each item separated by a 'hard return' or CarriageReturnLineFeed combination? Or is there some other character string separating the items? If this is a one-time occurrence to take this list and change it,I'd suggest copying the body of the list into an external text file. Then use the text editor (of your choice) to insert a pipe character | as a replacement for the deliminator. Then, manually insert a carriage return after every fifth entry to break the list up into columns. You will probably need to insert several other pipes to finish the task. Another possibility would be to use a language like 'awk' to process the list, but I don't think the learning curve justifies a one-time use. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups TiddlyWiki group.

[tw] Re: How to turn a hr-seperated list into a table with several columns?
First question, I m not familiar with the term hr-seperated list..
An 'HR-separated list' is a text-based syntax that I've developed and
used in numerous TiddlyTools plugins and inline scripts. Basically,
it's a tiddler containing lines of text, divided up into 'items' of
one or more lines, where each item is separated by a line containing a
TW HR (horizontal rule) syntax: newline-4 dashes-newline (i.e.,
\n\n).
Two examples of HR-separated lists:
http://www.TiddlyTools.com/#Quotations
and
http://www.TiddlyTools.com/#MiniBrowserList
If the first case, each item is a text entry (a quotation) that can be
randomly selected and displayed by QuoteOfTheDayPlugin. In the second
case, each item consists of two lines: the first line contains
descriptive text, the second line contains a URL. This information is
then used by MiniBrowserPlugin to populate the 'bookmarks' list.
To parse an HR-separated list in javascript code (plugin or inline
script) is easy:
var items=store.getTiddlerText(SomeTiddler,).split(\n\n);
This creates an array of strings, one for each item in the list.
Then, loop over those items to process each one. If each item has
multiple lines, you can further split the text into separate lines
(i.e., using .split('\n')). For example, to fill the 'bookmarks...'
droplist in MiniBrowser:
for (var i=0; iitems.length; i++) {
var lines=items[i].split(\n); // 1st line=description, 2nd
line=URL
list.options[list.length] = new Option(lines[0],lines[1]);
}
where 'list' is an HTML select element (i.e., a droplist/listbox)
For Mans' specific use case, you could write something like this using
http://www.TiddlyTools.com/#InlineJavascriptPlugin
script
var out=;
var items=store.getTiddlerText(SomeTiddler,).split(\n\n);
for (var i=0; iitems.length; i++) {
if (i0 i/5==Math.floor(i/5)) out += |\n; // start a new row
out += |+items[i]; // add item to row
}
out += |\n; // end last row
return out;
/script
The script constructs the desired TW table syntax into a string
variable (out), and then returns that string. InlineJavascriptPlugin
then automatically passes that returned text to the core's wikify()
function to render the table into your output.

[tw] Re: How to turn a hr-seperated list into a table with several columns?
Hi Eric - this is true magic : - )
Of course *you* would say that it's easy -
I only had a hunch - that it ought to be easy - considering what I've
seen uptill now!!
2 questions:
1)
If I could make it work with any hr-seperated lists like this:
tiddler TiddlerContainingScript with SomeTiddlerName
It would be even better...
I presume it's a matter of changing (SomeTiddler,) to ('$1','') ??
Am I on the right track?
2)
My next action with the hr-seperated list would be to add toggletag A
and toggletag B to each item - referring to the tiddlerLink -
Will it work in the table?

The script output is processed as TW wiki syntax, so any macros, etc.
that occur in the list items should be handled when the output is
rendered.

Can I automake a hr-seperated list from a normal lineseperated list with quickeditplugin in some way? If the tiddler contains single lines, you could use it as is, by changing the script from var items=store.getTiddlerText($1,).split(\n\n) to just var items=store.getTiddlerText($1,).split(\n); Alternatively, here's some general-purpose code that first tries to split the text on the HR separator... and if only one item results (i.e., there are *no* HR separators in the text), then tries splitting on just a simple newline, allowing either format to be used, as appropriate: var txt=store.getTiddlerText($1,); var items=txt.split(\n\n); if (!items[1]) items=txt.split(\n); enjoy, -e --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups TiddlyWiki group.
