Hey all!
I have fields in my TW that can contain macro shortcuts (<<macroname parameter>>). Those also contain elements I’m trying to style in a specific way in order to prettify the rendering of the field value wherever relevant. In order to style the relevant elements, I have to split[ ] on spaces, which will split the macro shortcuts as well, and even recomposing the field afterwards would render the macro shortcut calls as plain text:
Ex. of a rendering without doing anything specific to the macro shortcuts; they are recomposed correctly, but not computed, while the desired formatting is applied to the “1s” element of the field.
I figured I’d use conditionals to detect if a macro shortcut exists in the field value, then manipulate it so it’s preserved aside (replacing the space character with “?” in the example below), before doing the rest of the formatting that I want on the field (then replacing back the “?” with a space character). The below procedure (which is fed the value of a field to be parsed for formatting) is what I came up with:
\procedure timeparse2(value)
<% if [<value>regexp[<<\w+\s.+>>$]] %>
<$list filter=`[search:$(value)$:regexp[<<\w+\s.+>>$]]` variable="macroshortcut">
<!-- ^ I'm guessing this cannot work because the angled brackets would break the list widget? -->
(<<macroshortcut>>)
<$let tempvalue={{{ [<macroshortcut>search-replace[ ],[?]] }}}>(<<tempvalue>>)
<$list filter="[<tempvalue>split[ ]]" variable="seg" join=" ">
<% if [<seg>regexp[\d+s$]] [<seg>regexp[\d+m$]] [<seg>regexp[\d+h$]] [<seg>regexp[\d+d$]] %>
<$macrocall $name="time" value=<<seg>>/>
<% elseif [<seg>regexp[\d+s,$]] [<seg>regexp[\d+m,$]] [<seg>regexp[\d+h,$]] [<seg>regexp[\d+d,$]] %>
<$let segm={{{ [<seg>split[,]first[]] }}}>
<$macrocall $name="time" value=<<segm>>/>, </$let>
<%elseif [<seg>regexp[<<\w+.+>>$]] %>
{{{ [<seg>search-replace[?],[ ]] }}}
<% else %>
<<seg>>
<% endif %>
</$list>
</$let>
</$list>
<% else %>
<$list filter="[<value>split[ ]]" variable="seg" join=" ">
<% if [<seg>regexp[\d+s$]] [<seg>regexp[\d+m$]] [<seg>regexp[\d+h$]] [<seg>regexp[\d+d$]] %>
<$macrocall $name="time" value=<<seg>>/>
<% elseif [<seg>regexp[\d+s,$]] [<seg>regexp[\d+m,$]] [<seg>regexp[\d+h,$]] [<seg>regexp[\d+d,$]] %>
<$let segm={{{ [<seg>split[,]first[]] }}}>
<$macrocall $name="time" value=<<segm>>/>, </$let>
<% else %>
<<seg>>
<% endif %>
</$list>
<% endif %>
\end
Unfortunately, I’m guessing that using directly regexp[<<\w+\s.+>>$] cannot work because of the angled brackets in the filter expression (for the same reason using any square brackets in a regexp expression would also break the filter).
Does anyone know if there would be a simple way to handle such cases? I tried using functions like:
\function macro-regexp() [<<\w+\s.+>>$]
To then write the filter with:
<$list filter=`[search:$(value)$:regexp<macro-regexp>]` variable="macroshortcut">
But it didn’t work (actually breaking a whole lot of stuff). Maybe backtick substitutions would? Or is there another deeper factor that makes the use case tougher to handle?
