Hi Mohammad, Your macros show a deep knowledge of the tools in TW.
I'm a bit concerned that each level of indenture requires another chunk of code, which may be hard to maintain. The thing is, this sort of thing is easy if you have the right text tools. We need the concat function and a substr function. Unfortunately the new tools lack the substr. How do you feel about using javascript macros (and filters) in TW-commander? I just thought of another approach. Maybe. You could use a list filter and call it recursively. Each time you prefix a "0". When the length (new math function?) reaches the padded number length, the recursion ends and the result is sent back. The problem here is that I don't the parameters for the length function. The length would have to be compared to the target length and the only comparison tool is the revealwidget. -- Mark On Friday, February 15, 2019 at 8:31:53 AM UTC-8, Mohammad wrote: > > Mark, > String operation are added to TW - prerelease, see below > > Ref: > > - > > https://github.com/Jermolene/TiddlyWiki5/blob/master/core/modules/filters/strings.js > - > > https://github.com/Jermolene/TiddlyWiki5/commit/9b2d52716a24197ba9fd67b708cbe2c56fa1b5d0 > > > By the way, please let me know your opinion on the above macros. > > --Mohammad > > On Friday, February 15, 2019 at 7:57:17 PM UTC+3:30, Mark S. wrote: >> >> Like others in the forum, I'm finding that search links do not work.
