Splitting text to grab @strings to make some tags

[dieg...@gmail.com]

Hello friends,

I'm trying to take an input field that looks like:

this is some     aribrart text .. .etc. # ... @title1   @title2   @[[title with space]]

and parse it to tag another created tiddler with title1, title2 and [[title with space]].

Ive tried playing around with splitting by space, regexp for '@', etc but I cant seem to cleanly grab all titles.

Any help would be greatly appreciated!

Thanks,

Diego

Try this to get the tags (skip the enlist-input[] to keep them as one string):

<$vars text="""@title1   @title2   @[[title with space]]""" reg="""@(\[\[.*[^\]]\]\]|\S+)""">

{{{ [<text>search-replace:gi:regexp<reg>,[$1]enlist-input[]] }}}

</$vars>

I've played around with converting #title to tags in Streams using a similar technique.

I realized that the solution I posted above only works for my use case where the tags are on a line of their own.

I am sure someone with better RegExp prowess can improve on this significantly, but this should work:

<$vars text="""this is some     aribrart text .. .etc. # ... @title1   @title2   @[[title with space]]""" reg="""(?:(?:@(\[\[.*[^\]]\]\]|\S+))|(?!@)\S+|\s)""">

{{{ [<text>search-replace:gi:regexp<reg>,[ $1]enlist-input[]] }}}

</$vars>

Diego,

Try this below, notice the subtle difference in annotation for the spaced tiddler? Then in the remove prefix we are talking about the tiddlername.

\define input() aribrart text .. .etc. # ... @title1   @title2   [[@title with space]]

{{{ [enlist<input>prefix[@]removeprefix[@]] }}}

{{{ [enlist<input>prefix[@]removeprefix[@]] }}}

is identical to {{{ [enlist<input>removeprefix[@]] }}}

Depending on how the input text will be used, the change in syntax may have significant consequences for rendering of links, finding backlinks and freelinks etc.
