Sorry, forgot the MWE:

To fix the module you have to change the line
\edef\Ratio{\withoutpt{\the\dimexpr2\paperheight/(\PageWidth/32768)\relax}}
with (remove one pair of curly braces)
\edef\Ratio{\withoutpt\the\dimexpr2\paperheight/(\PageWidth/32768)\relax}
Similar problems can happens with other modules because many of them are
outdated
and they should be either updated or removed (the files can still be
archived).

you really want something like this then:
local tab = table.pack(...)
local rv = {}
This function just ignores non-table arguments because that is what I
usually want. You may want to throw an error instead. Also it uses
table.pack. You might need to use `tab = {...}` and ipairs, or implement
pack:
I might add table.himerged (hash and index) but slightly different (and
some 30% faster) to util-tab but i think merging mixed hash/indexed
tables is rare.

Looking at the code, I see what is happening. table.merge(d) assume that the
tables are key-value tables so the keys of the first table are silently
overwritten by the send. I guess, I'll have to write my own function to merge
"array" tables.

[NTG-context] Merging two lua tables
Hi,
How do I merge two lua tables? I believe that table.merge or table.merged
should do the trick, but I cannot figure out how to use them.
```
local t1 = { 1, 2 }
local t2 = { 8, 9 }
local m1 = {}
table.merge(m1,t1, t2)
table.print(m1)
local m2 = table.merged(t1, t2)
table.print(m2)
```
Processing the file with context filename shows that both m1 and m2 are {8, 9}.
What am I missing.
Thanks,
Aditya

Another, more general question on this: why is the function poetry.sidebyside
defined twice? If I understand correctly, depending on the input one or the
other will be used, but I don't see where that happens...
the first can be commented as it is the first simple variant

Re: [NTG-context] Parallel texts: verse with blanks between stanzas via tabulate
Thanks Hans, that's very nice indeed. Looks like I really need to dive into CLD. There seem to be so many possibilies... However, the major pitfall seems to be that this assumes stanzas of equal length (as it relies on \TB to produce the blanks), which does not apply to my situation. (Modfied version attached.) Do you see any way to support this kind of situation? Best, Denis > -Ursprüngliche Nachricht- > Von: Hans Hagen > Gesendet: Sonntag, 28.
