I created a new
* bottom anchor to all masters, and set the context to
reh-ar * on all masters as well, but I don’t see any new lookups in the exported font.
I created a new
Did you miss-type it here? It shouldn’t have a space in the name.
OK, I got this to work after removing the space. Now I need to specfiy another mark in the context, namely I want this contextual anchor to be used if the current glyph is followed by
dotcenter-ar, so I used
* dotcenter-ar as context but it does not seem to work.
So basically the code I want Glyphs to generate is:
pos base hah-ar dotcenter-ar <anchor 146 -359> mark @mark_bottom';
But what I get is:
pos base hah-ar <anchor 146 -359> mark @mark_bottom' dotcenter-ar;
As far as I understand the spec, the second line should be correct. Can you explain the difference? What exact input string do you have in mind?
The input glyph sequence is
hah-ar dotcenter-ar kasra-ar. The text input is جِ (I decompose in camp). I also need to use mark filtering set so that the condition matches if there other marks between the dot and the kasra, e.g.
hah-ar dotcenter-ar fatha-ar kasra-ar.
Contextual marks seems to not work with ligatures at all. No lookups are generated.
Is the dotcenter influencing the position of the kasra? If not, shouldn’t it just filtered out?
I’ll have a look at the other cases, soon.
Yes it does. If there is no dotcenter, I want the kasra to be inside the hah, but if dotcenter is present I want the kasra below the hah.
Ok. I understand.
That needs an extension to the context string format.
I have two ideas:
- Specify backtrack, input and lookahead by comma-separating each:
,* dotcenter-ar,(backtrack and lookahead is empty)
- or, add another placeholder to denote where the
<anchor x y>should go:
* dotcenter-ar @
I tend to option 2.
Option 2 looks more flexible, so I vote for that one as well.
I can confirm this. Working on a Telugu font with lots of ligatures – no contextual mark lookups for
blwm generated. Normal mark to base lookups in
blwm work fine (in case you wondered if the whole thing was setup correctly).
How would contextual mark-to-liga FEA code would look like?
Facing the same issue.
I am using Glyphs 3.2 (3192).
I have placed mark with
"*bottom.reh" name, and anchor context
"reh-ar.fina *" in behDotless-ar.
No result in InDesign (latest).
Can you send me the .glyphs and the indesign file?
Thanks for the reply.
will send the files shortly.
Meanwhile I noticed another strange behavior,
Here is a screen shot of my anchors in behDotless-ar:
and the Anchor Context like so:
Now, when I type Kasra after teh-ar it is positioned on that contextual anchor instead of default bottom anchor.
I have emailed you the files. Waiting for your response.
Thanks and regards.
This should be fixed.
