Hi, Sylvain.
This is a simple example. It can only handle Chinese right now, but
maybe could serve as a starting point for your further work.
```lmtx
\usetypescriptfile[mscore]
\usebodyfont [mschinese,10.5pt]
\startluacode
Thirddata = Thirddata or {}
local glyph_id = nodes.nodecodes.glyph
local node_insertbefore = node.insertbefore
local node_insertafter = node.insertafter
local node_new = node.new
local tex_sp = tex.sp
local function ischinesechar(c)
-- cjk汉字，不含符号
-- for more ranges:
-- https://wiki.contextgarden.net/List_of_Unicode_blocks
return (c >= 0x04E00 and c <= 0x09FFF) --CJK Unified Ideographs;
cjkunifiedideographs
end
-- 汉字环境中的（非汉字）合法符号
local legalsymbolinchinese = {
[0x00b7] = true, -- · MIDDLE DOT
[0x002D] = true, -- - Hyphen-Minus. Will there be any side effects?
[0x002F] = true, -- / Solidus
}
local function islegalsymbolinchinese(c)
return legalsymbolinchinese[c]
end
function Thirddata.processmystuff(head)
local n = head
while n do
if n.id == glyph_id then
if ischinesechar(n.char) then -- 本字是汉字
local n_prev = n.prev
if n_prev and n_prev.id == glyph_id then
if ischinesechar(n_prev.char) then -- 前字是汉字
elseif not islegalsymbolinchinese(n_prev.char)
then --前字不是汉字也不是合法中文语境符号
local glue = node_new("glue")
glue.width = tex_sp("0.25em")
glue.stretch = tex_sp("0.25em")
--print("insert space before:", utf8.char(n.char))
head, glue = node_insertbefore(head, n, glue)
end
end
local n_next = n.next
if n_next
and n_next.id == glyph_id
and not ischinesechar(n_next.char)
and not islegalsymbolinchinese(n_next.char)
then
local glue = node_new("glue")
glue.width = tex_sp("0.25em")
glue.stretch = tex_sp("0.25em")
--print("insert space after:", utf8.char(n.char))
head, glue = node_insertafter(head, n, glue)
n = glue.next
end
end
end
n = n.next
end
return head, done
end
nodes.tasks.appendaction("processors", "after", "Thirddata.processmystuff")
\stopluacode
\starttext
\dorecurse{50}{口口abc口口123口口abc123口口123abc}
\stoptext
