I have a string with double quotes that needs to become a text in a box in
METAPOST. METAPOST is used to create an image consisting of boxes and

> field 'sha
In a Lua function called from within an \startxmlsetups..\stopxmlsetups code
block I would like to search through the current node and all below.
Using string.match("to-be-searched”,”pattern”).
The Lua function being called through
\def\findmypattern#1#2{\ctxlua{tex.print(hvdm.findmypatter
/tex/context/third/drops/t-drops.lua:1098: in
upvalue 'get_IM_paths'
/home/adityam/texmf/tex/context/third/drops/t-drops.lua:1380: in field
'shadow'
[ctxlua]:1: in main chunk
This is due to the change in Lua5.3 with respect to floating point
numbers. The simplest solution is to change '%d
finished string
near eof”. Obviously caused by the %’s.
How to get this working? \textpercent will not do, off course within
Luacode.
% = \letterpercent
$ = \letterdollar
You can also replace
\directlua{tex.print(...)}
with
\ctxlua{context(...)}
or
\cldcontext

Sorry, but I’m afraid I don’t see the way of generating an URL to a
non-external document in your code.
After all, the document is embedded in the PDF document itself.

I am embedding links to an UR in my documents. Although it is used in
XML-documents, you might be able to use the gist of this code that generates a
clickable link. Perhaps you find it useful.

in your case the glyphs have no real useful names so basically i wonder
what their use it (are they meant for direct access?)
you can define
\def\byindex#1{\ctxlua{
for k, v in pairs(fonts.hashes.identifiers[true].characters) do
if v.index == #1 then
tex.print(utf.
end
end
end

.sequence) then
local units = shapedata.units or 1000
local factor = 100/units
local paths = fonts.metapost.paths(glyph,factor)
return paths
end
