Number formatting

[taale...@gmail.com]

I haven't found anything that quite addresses what I'm looking for. Specifically, I'm looking for something that works like Excel's format function, so that I can specify that the number 12 appears as 00012 (= excel's "00000"), for example. Is there anything that does that already?

There is a pad[] filter operator in the very soon to be released TW 5.1.23

prior to TW5.1.23, padding can be done using split[] and join[], like this:

<$vars num="12">

{{{ [<num>addprefix[00000]split[]last[5]join[]] }}}

<$vars>

The resulting output is "00012".  Note that if the num value has more than 5 digits, it will be truncated to only show the last 5 digits.

This thread has what I needed: https://www.mail-archive.com/tiddl...@googlegroups.com/msg91214.html

Well, that's not quite the solution after all, because I keep getting this error:

Uncaught RangeError: Maximum call stack size exceeded 

I don't have issues with the macro on tiddlywiki.com, so I don't know what I'm doing wrong. Can anyone figure out what's wrong?

I'm using the macro in the caption field like this:

<$macrocall $name="padder" str={{!!cnum}} len=2/>: {{!!title}}

The idea is to have the title replaced in link-lists with the caption, which shows the card number (cnum) and the title of the card, ala "05 : Cilantro" or "08 : Emerald".

And just in case, this is the macro definition I used (from that link I posted before, which is Mark S's code:

\define padder-reg() ^$(len)$$ 

\define padder(str,len,chr:"0") 

<$vars len=<<__len__>>> 

<$list filter="[<__str__>addprefix<__chr__>]" variable="padstr">

<$list filter="[<padstr>length[]!regexp<padder-reg>]" emptyMessage=<<padstr >>>

<$macrocall $name="padder" str=<<padstr>> len=<<__len__>> chr=<<__chr__>>/> 

</$list> 

</$list>

</$vars>

\end

This error is indicative of a run-away recursion.  Without digging into the code myself, I'm not sure why this is the case.  In any event, I suggest entirely avoiding the complexity (and processing overhead) of recursion by using the following alternative macro definition:

\define padder(str,len) {{{ [[$str$]addprefix[0000000000]split[]last[$len$]join[]] }}}

This will work to pad numbers up to 10 digits long (as determined by the number of zeros in the addprefix[...] operator) and you would use it in exactly the same way as the recursive macro:

<$macrocall $name="padder" str={{!!cnum}} len="2" />

Note that, starting with the soon to be released TW v5.1.23, there is a new filter operator, pad[...], which will accomplish the same result without needing any custom macro definition.

To use this new filter, you would just write the following inline filter instead of using <$macrocall ...>

{{{ [{!!cnum}pad[2]] }}}

enjoy,

Thanks Eric! That works - except not in the caption field. Still get the recursion error. I think waiting until v23 is out will have to do. 

Do we have an ETA yet?

"very soon"... in the meantime, you can upgrade to use the pre-release 5.1.23, here:

https://tiddlywiki.com/prerelease/upgrade

Then, once 5.1.23 is official, you can upgrade again, to get any last-minute fixes, using:
