Re: [NTG-context] Emoji color fonts not working on LMTX/Context MKIV

Pablo pointed out the bug in Evince. Sorry too. I've used another PDF
viewer and SVG color displays correctly. Thanks.

Many thanks for your reply, Hans.

icons are black and white, no color after wiping the cache.

Made no difference with a brand-new install either.

Just accidentally, I discovered this is an issue in Evince.

LMTX should handle color in LMTX with other PDF code than in MkIV.


won't happen ... actually, at some point mkiv will use a similar method 
as lmtx



MuPDF displays colorful. So do acroread for Linux, xpdf, SumatraPDF and
even Okular.

Sorry for the noise, since Evince seems to be the culprit.
for me acrobat and mupdf based viewers (sumatra also uses it, actually a 
rather old version) are the reference .. it makes no sense to cripple 
context because of an issue with a viewer

I did. It turns out that installing graphicsmagick does the trick (pun
intended) for Noto Color Emoji. However, the issue persists for SVG fonts
and the same message appears, despite of having cleaned the cache (I've
used mtxrun --script cache --erase). Using the code Pablo sent, with
EmojiOne Color instead of Twemoji Mozilla, I get the following error
messages:

Re: [NTG-context] Proposal to update the "Manuals" wiki page

[context]

Hello Garulfo,

thanks for the great work!

Two suggestions:

1. Obsolete manuals: Could their pictures be scratched somehow? One will 
see on the first sight that he is to investigate "no-more-valid" stuff.


2. Could you add a "download all manuals" hlink/button next to each 
(sub)title to download appropriate manuals as .zip, so to get:


"
Up-to-date Documentation (title) 
[download-all-up-to-date-manuals-in-this-section-inc-subsections 
(hlink)]

...
Graphics and Colors (subtitle) 
[download-all-graphics-and-colors-manuals-inc-subsections (hlink)]

...
"

- IMHO it would be good for offline users (and for those who prefer 
printed form).


Best regards,

Lukas

It's mainly built from cvs table + script.

Finally, if you approve this update, I can arrange to clean up some

[NTG-context] Text to be placed into the free space after columns and end of the page

[context]

Hello,

suppose the minimal example:


\showboxes
\starttext
  \startcolumns[n=2,balance=no,]
\input knuth
  \stopcolumns
  \vfill
  abcd
\stoptext


This produces two page document with columns on the first page and text 
"abcd" on the second.


But - I want the text "abcd" to be placed to the bottom of the same page 
as columns are (thus I attempted to put \vfill into the code, but it 
doesn't work), so to get one page document looking like:


+-- page width -+
Column text | (unused)
column text |
column text |
column text |
column text |
column text |

(some vertical space)

abcd
+- end of page -+

- How to achieve this?

Best regards,

Lukas
\showboxes
\starttext
  \startcolumns[n=2,balance=no,]
\input knuth

Re: [NTG-context] Proposal to update the "Manuals" wiki page

Hi,

I hope you're all doing well.

Please, you will find a proposal to update the Manuals page on the wiki:
https://wiki.contextgarden.net/ManualsGallery

2 objectives:
1/ to make something more visual, to help the user identify the 
different documents, their organization, their date of release.

2/ to gather all the updated documents in one place

Sources were :
- http://www.pragma-ade.com/overview.htm
- https://wiki.contextgarden.net/Manuals, and wiki snippets here and there.
- https://github.com/hmenke/context-examples/blob/master/GUIDE.md

Depending on your comments, and if there is an interest, I would be 
happy to improve it (correct errors, change document segmentation, 
better colors choice, additional data such as authors, number of pages).


It's mainly built from cvs table + script.

Finally, if you approve this update, I can arrange to clean up some 
pages of the wiki about the manuals.

Nicely done.

Hans

Ok, I've found the problem: context.lua and mtxrun.lua in
texmf-linux-64/bin did not have the execute permissions. It works after
adding the permissions.

Thanks,

Which file is closed here? Experiments with a custom format suggest that the 
read
files are opened through the `open_data_file` callback, so even if they
are closed they probably should be closed by calling the `.close` member
of the returned table. But that never happens (This might be a related
bug: In my experiments, even for files loaded with `\input`, the close
function is never called.) and the issue seems to occur even if there is
no real file opened for this. So I don't see why LuaMetaTeX should call
fclose here at all. But anyway, thanks for looking into this.
end_file_reading is always called but has to close selectively, 
dependent on what has been opened,  eep in mind that a token list or so 
is also an input stream

[NTG-context] Emoji color fonts not working on LMTX/Context MKIV

[Jairo A. del Rio]

I've tried the following from the manuals and adapted some code to see if
it works:

1.
\definefontfeature[svg][svg=yes]
\definefontsynonym[Emoji][file:emojionecolor-svginot.ttf*default,svg]
\definesymbol[bug][\getglyphdirect{Emoji}{\char"1F41B}]
\starttext
\symbol[bug]
\stoptext

The emoji has no color when compiled with LuaTeX. Furthermore, the log
includes a lot of lines like the ones below:


fonts > svg conversion > executing runner 'otfsvg': inkscape
--export-area-drawing --shell > temp-otf-svg-shape.log


fonts > svg conversion > processing 1829 svg containers

xml > core > load error: invalid xml file - parsed text

With LMTX it gives an error about mlib-svg.

2.

\definefontfeature[overlay][default][ccmp=yes,colr=yes,dist=yes]
\definefontfeature[svg]
[default][svg=yes]
\definefontfeature[bitmap] [default][sbix=yes]
\definefontfeature [colored] [default]
[ccmp=yes,dist=yes,
colr=yes,svg=yes,sbix=yes]
\definefontsynonym[Emoji][file:notocoloremoji*default,colored]
\definesymbol[bug][\getglyphdirect{Emoji}{\char"1F41B}]
\starttext
\symbol[bug]
\stoptext

What I get is:

fonts > png conversion > processing 3374 png containers


sh: 1: gm: not found


sh: 1: gm: not found


sh: 1: gm: not found sh: 1: gm: not found

...

and the same line repeating itself
...

close source > level 1, order 3, name
'/home/lol/lmtx/tex/texmf-context/tex/context/base/mkiv/cont-yes.mkiv'

! error: (file /usr/share/fonts/truetype/noto/NotoColorEmoji.ttf) (ttf):
loca table not found


LMTX prints a file without any emoji.


Only Twemoji Mozilla and Segoe UI Emoji worked for me, so, what am I doing
wrong?


I'm working with Ubuntu 20.04 LTS x86_64 and Inkscape 0.92.5 (2060ec1f9f,
2020-04-08) in case it helps. Thank you in advance.
