[NTG-context] Re: Is there any way to automatically control the spacing between Chinese and non-Chinese characters?

I'm curious what Chinese font(s) you are using with ConTeXt? Are they OpenType font, or TrueType? October 2, 2024 at 12:56 PM, "黄复雄" wrote:

This is a preliminary solution for inserting spaces between Chinese

```ConTeXt

local node_insertbefore = node.insertbefore

local node_insertafter = node.insertafter

local node_new = node.new

local tex_sp = tex.sp

local function ischinesechar(c)

-- for more ranges:

return (c >= 0x04E00 and c <= 0x09FFF)

or (c >= 0x03400 and c <= 0x04DBF)

or (c >= 0x20000 and c <= 0x2A6DF)

end

function Thirddata.processmystuff(head)

local n = head

while n do

if n.id == glyph_id and ischinesechar(n.char) then

local n_prev = n.prev

if n_prev

and n_prev.id == glyph_id

and not ischinesechar(n_prev.char)

then

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

local n_next = n.next

if n_next

and n_next.id == glyph_id

and not ischinesechar(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

n = n.next

end

return head, done

end

hi,

Is there any way to automatically control the spacing between Chinese and non-Chinese characters?

I noticed that there is a tracker that tracks character types and annotates them.

But I don't know much about lua and the underlying tex.

Any suggestions would be greatly appreciated.

For example, glue is automatically added between Chinese characters and English or numbers.
