Switching fonts changes framedtext justification

Switching fonts changes framedtext justification

[Thangalin via ntg-context]

Hi all,

The following code produces framed text areas, each having different
justification:

\definefont [TextFontEmoji] [OpenSansEmoji]
\definefontfamily [TextFont] [rm] [LibreBaskerville]
\setupbodyfont [TextFont]

\starttext
  \startframedtext
    \TextFontEmoji
    \input ward
  \stopframedtext

  \startframedtext
    \input ward
  \stopframedtext
\stoptext

How would you ensure that both text areas remain fully justified?

Thank you!

I don't have that Emoji font, but replacing it with other fonts,
framedtext justifies the text here.

Are you sure it's not a tolerance issue? Frames don't inherit the
tolerance from the main environment¹. Try with

  \setupframedtext
    [align=verytolerant]
    %% [align={verytolerant, stretch}]

I think (at least) LMTX has an issue with the font:

  \definefontfamily [TextEmoji] [rm] [OpenSansEmoji]
  \setupbodyfont [TextEmoji]
  \starttext
  \input knuth
  \stoptext

I’m afraid I cannot test this with MkIV.

Confirmed there is a font issue with LMTX.

$ context --version
mtx-context     | current version: 2022.04.01 09:37

The issue was also present with version 2021.11.30.

> Are you sure it's not a tolerance issue?

Pablo's example also doesn't justify, so \framedtext is a red herring.

The .otf file is from:

https://github.com/MorbZ/OpenSansEmoji

Thanks everyone!

That’s 9 years old. The linked resources were updated later and are 
still outdated. There must be a better Emoji font out there?

You would think so. I haven't found any that are free for
personal/commercial, open-source, black & white, and work with
ConTeXt. Here's one list of various fonts:

https://graphicdesign.stackexchange.com/a/117696/4902

The Noto Color Emoji font includes Noto B&W Emojis:

https://github.com/googlefonts/noto-emoji/raw/main/fonts/NotoColorEmoji.ttf

But it seems the Unicode glyphs and Latin glyphs won't appear at the
same time. (Each glyph would have to be wrapped in its own font macro.
Open Sans Emoji has glyphs that are a bit more print-friendly and
supports both Latin and Emoji glyphs.)

Thanks for taking a look.

The font is too old, but the TTF version works just fine on both Linux
and Windows.

Just in case it may help,

No dice with LMTX 2022.04.01 09:37 and the TTF file. Using the TTF,
the emojis don't appear, but the text is justified. Using the OTF, the
emojis appear, but the text is unjustified.

What version of ConTeXt are you using, Pablo?

Both things work on both Linux and Windows systems.

  \definefontfamily[emoj][rm][OpenSansEmoji]
  \setupbodyfont[emoj]
  \starttext
  \startTEXpage[offset=1em, align=center]
  Welcome to the future,\\human 👽!
  \stopTEXpage
  \startframedtext
  \input zapf
  \stopframedtext
  \stoptext

> What version of ConTeXt are you using, Pablo?

Current latest from 2022.04.01 09:37. Binaries for 64bits on both OS.

Just in case it may help, I recommend the following approach.

1. Remove the file OpenSansEmoji.ttf.
2. Remove the directory tex/texmf-cache/luametatex-cache.
3. Run mtxrun --generate.
4. Compile the sample above.

BTW, "mtxrun --scripts cache --erase" doesn’t work for me (just in case
anyone wonders).

I hope it may help,

Pablo

Appreciated, Pablo.

The output remains unjustified:

https://i.ibb.co/dM9LFWZ/future-human.png

$ find /usr/share/fonts/ -name "*Emoj*"
/usr/share/fonts/emoji/OpenSansEmoji.otf

$ context --version
mtx-context     | current version: 2022.04.01 09:37

$ cat ~/bin/fontcache
#!/usr/bin/env bash

fc-cache -fv
mtxrun --generate
mtxrun --script fonts --reload

$ cat ~/bin/fontgrep
#!/usr/bin/env bash
mtxrun --script fonts --list --all --name $1 | cut -d" " -f1

$ fontgrep emoji
identifier

opensansemoji
opensansemojinormal
opensansemojiregular

Any other suggestions?

Thank you!

Sorry, I gave you the wrong direction.

The OTF version has to be removed, not the TTF version (it is the one
that works).

I already knew that
(https://mailman.ntg.nl/pipermail/ntg-context/2022/105409.html), but I
mixed (and messed) versions.

Sorry, "OpenSansEmoji.otf" is the one to be removed and
"OpenSansEmoji.ttf" is the one to be installed.

I had problems in the past with "mtxrun --script fonts --reload
--force", so I completely remove the contents from
"tex/texmf-cache/luametatex-cache/" (which requires "mtxrun --generate"
after).

"mtxrun --script cache --erase" used to do the same, but I cannot get it
working now (either on Linux or in Windows [as reported in
https://mailman.ntg.nl/pipermail/ntg-context/2022/105420.html]).

> Any other suggestions?

I hope it works now. Sorry for the mess,

Pablo

Works flawlessly, thank you!

Here's a demo with left and right speech bubbles:

\definefont [TextFontEmoji] [OpenSansEmoji]

\startuseMPgraphic{TextBubble}{side}
  z1 = (0, 0) ;
  z2 = (OverlayWidth, 0) ;
  z3 = (OverlayWidth, OverlayHeight) ;
  z4 = (0, OverlayHeight) ;

  offset := 1 ;
  tail := 1 ;

  % Flip the tail's location and direction.
  if \MPvar{side} = 1:
    offset := 5 ;
    tail := -1 ;
  fi

  (offset/6)[x1,x2] = x8 + .25cm * tail = x7 + .25cm = x9 - .25cm ;
  y7 =  0cm ;
  y8 = -.5cm ;
  y9 =  0cm ;

  path p ;
  p = (z1--z7--z8--z9--z2--z3--z4--cycle) cornered .25cm ;
  draw p withpen pencircle scaled 0.75 ;

  setbounds currentpicture to OverlayBox ;
\stopuseMPgraphic

Thank you for the speech bubbles! This is something I need for the 
messenger chats in my novel. Will be a good learning experience to adapt 
your solution to my ideas.

Re: Switching fonts changes framedtext justification

[Thangalin via ntg-context]

I certainly can't claim credit for the speech bubbles!

https://wiki.contextgarden.net/index.php?title=Speech_bubble
https://mailman.ntg.nl/pipermail/ntg-context/2011/056496.html

I modified Wolfgang's code to provide a control for the tail, and,
thanks to Pablo, a decent font for embedding emojis.

There are a couple of problems with the speech bubbles that could use
fixing. First, the ability to have a fixed offset for the tail (e.g.,
2 em from the left and 2 em from the right). Second, when the speech
bubble is too short (e.g., a single emoji), the tail gets mangled.

Here's a screenshot showing speech bubbles using annotated Markdown:

https://github.com/DaveJarvis/keenwrite/releases

The ::: bubbletx eventually becomes a startbubbletx/stopbubbletx pair.

Greets!
