Help with ForEachTiddler

[magev958]

Hi, I been tinkering with TiddlyWiki for some time now and starts to
get the hang of it, but my programing skills is an empty hole.
I found great piece of code (I think it was here) for the plugin
ForEachTiddler that display just the first bit of every tiddler in
order. Works great, but I'd like to limit the number of tiddler it
displays to say 5. How do I get about to do that?

<<forEachTiddler
where
'tiddler.tags.contains("information")'
sortBy
'store.getValue(tiddler,"created")'
descending
write
'"\n@@font-size:1.5em;[["+tiddler.title+"]]@@@@color:#999; - " +
Date.convertFromYYYYMMDDHHMM(store.getValue(tiddler,"created")).formatString("YYYY/
0MM/0DD")+" - "+tiddler.modifier+"@@\n" +
"{{excerpt{\n" +
(tiddler.text.match("/%%/") ?
tiddler.text.substr(0,tiddler.text.indexOf("/%%/")) :
tiddler.text.substr(0,300)) +
" ...\n[[more ...|"+tiddler.title+"]]\n----\n}}}";'
>>

Thanks in advance/

Hi magev958

You'll need '(index < 5) ?

ForEachTiddler that display just the first bit of every tiddler in
order. Works great, but I'd like to limit the number of tiddler it
displays to say 5. How do I get about to do that?

Try (untested

)

<<forEachTiddler
 where
 'tiddler.tags.contains("information")'
 sortBy
 'store.getValue(tiddler,"created")'
 descending
 write

 '(index < 5) ?"\n@@font-size:1.5em;[["+tiddler.title+"]]@@@@color:#999; - " + 

Date.convertFromYYYYMMDDHHMM(store.getValue(tiddler,"created")).formatString("YYYY/
0MM/0DD")+" - "+tiddler.modifier+"@@\n" +
 "{{excerpt{\n" +
 (tiddler.text.match("/%%/") ?
 tiddler.text.substr(0,tiddler.text.indexOf("/%%/")) :
 tiddler.text.substr(0,300)) +
 " ...\n[[more ...|"+tiddler.title+"]]\n----\n}}}";'
>>

See http://tiddlywiki.abego-software.de/#%5B%5BList%20the%20first%2010%20tiddlers%20that%20have%20the%20tag%20'basic'%5D%5D

[whatever]

<<forEachTiddler
where
'tiddler.tags.contains("information")'
sortBy
'store.getValue(tiddler,"created")'
descending
write

'(index < 5) ? tiddler.title+"\n" : ""'>>

That should do it, just replace tiddler.title+"\n" with your own code
in quotes. I had some trouble with your code, so you might want to
debug it. As far as I can tell, the quotes @@\n" + "{{excerpt{\n are
not necessary, since this is all a literal string.

Wow, that was fast!
Thanks for your suggestion, unfortunate it did not work :(
When I add the

'(index < 5) ?

all I get is a error

<<forEachTiddler ...>>:SyntaxError: Parse error

The code is not mine, I found it in this forum so I don't know what
and how it works, but it shows the title, creator, date and the first
lines of the tiddler very beautiful :)

This should do it:

<<forEachTiddler
where
'tiddler.tags.contains("information")'
sortBy
'store.getValue(tiddler,"created")'
descending

script
'
function getFirstLine(s) {
var m = s.match(/\s*(.*)/);
return m != null && m.length >= 1 ? m[1] : "";
}
' write
'(index < 5) ? "[["+tiddler.title+"]] - "+tiddler.creator+" -
"+tiddler.created+" - "+getFirstLine(tiddler.text)+"\n" : ""'>>

Oh yeah, I think you might have forgot to add : "" at the end, that's
why you probably got the error.

Now tested with your codesnippet - you'll need to replace the last ; with :"" as whatever says:

<<forEachTiddler 

 where 

 'tiddler.tags.contains("information")' 

 sortBy 

 'store.getValue(tiddler,"created")' 

 descending 

 write 

 '(index < 5) ?"\n@@font-size:1.5em;[["+tiddler.title+"]]@@@@color:#999; - " + Date.convertFromYYYYMMDDHHMM(store.getValue(tiddler,"created")).formatString("YYYY/0MM/0DD")+" - "+tiddler.modifier+"@@\n" +  "{{excerpt{\n" + (tiddler.text.match("/%%/") ? tiddler.text.substr(0,tiddler.text.indexOf("/%%/")) :  tiddler.text.substr(0,300)) + " ...\n[[more ...|"+tiddler.title+"]]\n----\n}}}":""' >>

An alternative idea:

You could use a hidden section "note" instead of firstlines (i.e some comment) and use Eric's EditSectionPlugin like this:

<<forEachTiddler 

 where 

 'tiddler.tags.contains("information")' 

 sortBy 

 'store.getValue(tiddler,"created")' 

 descending 

 write 

 '(index < 5) ?"\n@@font-size:1.5em;[["+tiddler.title+"]]@@@@color:#999; - " + Date.convertFromYYYYMMDDHHMM(store.getValue(tiddler,"created")).formatString("YYYY/0MM/0DD")+" - "+tiddler.modifier+"<<editSection [["+tiddler.title+"##note]] ✎\>\>@@\n" +  "><<tiddler [["+tiddler.title+"##note]]\>\>\n----\n":""' >>
