Emanuel,
Your sample seems to work fine on CTX MKIV 2024.01.24 version , as far
as I see the final PDF output. And ConTeXt doesn't complain, even in the
log !

Hi all,
I added
https://wiki.contextgarden.net/Chinese_Japanese_and_Korean#Meeting_the_JIS_X_4051_Requirements_for_Japanese_Text_Layout
with attached working example code and to-do list.
Thanks for any contributions!
The working example code is still a work in progress. Its text layout
output meets already some of the requirements (see comments in the
code). Among the ones to still be implemented are:
*
solid setting (no extra spacing between characters)
https://www.w3.org/TR/jlreq/#fig1_8 if no requirement for
line-adjustment https://www.w3.org/TR/jlreq/#term.line-adjustment
*
aligning of the lines to the Kihon-hanmen (optimizing the code
below in this regard)
*
positioning and realm of headings
https://www.w3.org/TR/jlreq/#fig3_1_9
https://www.w3.org/TR/jlreq/#fig3_1_15 et al, and
https://www.w3.org/TR/jlreq/#fig3_1_4
*
positioning of yokugo-ruby https://www.w3.org/TR/jlreq/#fig2_3_24
*
inline cutting note (warichu) https://www.w3.org/TR/jlreq/#fig2_4_1
*
emphasis with sesame dot or bullet
*
itemization https://www.w3.org/TR/jlreq/#fig2_5_6
*
indenting of quotation paragraphs
https://www.w3.org/TR/jlreq/#fig2_5_7
*
tab setting https://www.w3.org/TR/jlreq/#fig2_6_1
*
furiwake https://www.w3.org/TR/jlreq/#fig2_7_2
*
jidori https://www.w3.org/TR/jlreq/#fig2_7_4
*
math https://www.w3.org/TR/jlreq/#fig2_7_6 and
https://www.w3.org/TR/jlreq/#fig2_7_62
*
tategaki (writing vertically)
Best regards
Emanuel

Dear Wolfgang,
thank you for your valuable remarks. I integrated them, see
corrected attached example.
Yes, correct layout examples exist. They're all showing
vertical writing, but the rules and principles are exactly the
same for horizontal writing.
*
position of the headers and footers:
https://www.w3.org/TR/jlreq/#fig1_30
See my attached gongitsune.tex example how you can squeeze text in
a very narrow header/footer.
*
aligning lines to the text box:
https://www.w3.org/TR/jlreq/#fig1_3
You can use the lines key for \setuplayout to let ConTeXt
calculate the necessary value for the text height.
*
protrusion of ruby: https://www.w3.org/TR/jlreq/#fig_ad1_6
You're getting this for free because ruby text doesn't take up
vertical space, in case vertical text is working it would now
stick into the margins as expected.
\starttext
\ruledhbox{a \ruby{x}{y} b}
\stoptext
*
In my previous mail, I wrote wrong amounts of lines. They
should be 46 lines on one page, while the actual example
doesn't show the 46th line.
It would be important to identify the reason why only 24
characters are used to create a line when 25 could be used.
Then we can develop a method to turn that mechanism off or
circumvent it.
Quotation from https://www.w3.org/TR/jlreq:
/In principle, when composing a line with //ideographic
(cl-19) <https://www.w3.org/TR/jlreq/#cl-19>//, //hiragana
(cl-15) <https://www.w3.org/TR/jlreq/#cl-15>// and //katakana
(cl-16) <https://www.w3.org/TR/jlreq/#cl-16>// characters, no
extra spacing appears between their //character frame
<https://www.w3.org/TR/jlreq/#term.character-frame>//. This is
called solid setting (see //Figure 5
<https://www.w3.org/TR/jlreq/#fig1_8>//)./
1. ConTeXt has a mechanism to typeset Japanese texts.
2. There are flaws in the output it produces but this nothing
which can't be fixed.
3. To fix the problems someone has to be passionate to fix them
and we're willing to help here.
As you can see in my second example file japanese.tex there is a
font feature to create half sized parentheses etc. which isn't
supported yet by ConTeXt's mechanism for japanese and in case your
willing to improve it this should be taken care of as well.
Wolfgang
