no, tex is not a library .. but of course you can make a small tex file 
that wraps your lua and run that file with context


keep in mind that tex is a ecosystem: fotns, languages etc

Sorry for not being precise enough.

I'm not sure I understand. This example shows two poems side by side. Both are 
totally different in structure. One has a heading, and consists of multiple 
paragraphs. The other is just one long stanza. Until now, I've used tabulate 
for these kind of sidebyside texts. Usually there are not poems, just regular 
paragraphs, but with poems I've realized that blanks seem not be supported in 
individual table cells.

You need to be more prececise in defining what you want .. this example 
is not a parallel obe right? Just two columns.

I see.



Thanks for the updated version. So, that means the basic restriction is that 
blanks will need to be inserted between rows, right? We cannot have to two 
completely independent formatted poems, right? (For reference, see the attached 
PNG. This was done with paragraphs, and works as longs as this stays on a

stanzas.)

Re: [NTG-context] Merging two lua tables

2022-08-30 Thread BPJ via ntg-context 
Come to think of it you may also want to check that numeric indices are
indeed positive integers before appending their value. I usually don't
because their not being so is rare.

Thanks. I was manually translating from MoonScript (https://moonscript.org)
where variables are local by default.
