Re: OpenType Features: Order of Precedence

How about adding some standard fractions for powers? Powers.png I also looked for ways to accommodate thousand separators and periods. I have a kerning class that includes period, comma, and ellipsis. By adding a substitution for that with hair space, numerators work OK, but denominators break the f...

Re: OpenType Features: Order of Precedence

Would this work if both frac and ordn are activated: That looks fine to me. However, I am not too sure if the superscripted x in 2x would be expected. As far as I know, only d, h, n, r, s, t, è and ú are valid for ordinal numbers , but there may be others in other languages. Abbreviations like M ll...

Re: OpenType Features: Order of Precedence

I think, if only fractions are enabled it should do this: Frac.png If both fractions and ordinals are enabled it should probably do this: Frac + Ordn.png Or perhaps this, but I think that not all of a-z should be included in Ordinals, though that's a moot point: Frac + Ordn 2.png I am still trying t...

Re: OpenType Features: Order of Precedence

I think we're getting way too ambitious here.

I don't think we need 13 chaining contexts, or an equation editor.

A fraction feature that can cope with 123/456 or (1+2)/(abc-xyz) without conflicting with Ordinals would already be quite impressive.

Re: OpenType Features: Order of Precedence

I'm sure we can get both to work for the basics, but what about more complex formulas, or even just something like: 1st = 2x + 1/3y - (34/456)z and 2nd = 0 If one writes (2x+1)/3y-(34+456) it can work, but I don't think the slash can be used twice, even if one adds a subscripted slash to the font. ...

Re: Variables to Generate Glyph maps

Sorry for bumping this post but it seems to be along the same subject I am suggesting so I just post here... There is not much point in bumping a thread in the Implemented Feature Requests forum to request something different. I have therefore split your post and Erwin's reply to a new topic in the...

Re: Chaining Context: Ligatures following numerals

When it comes right down to it, ordn shouldn't be turned on globally. It should be turned on for the run of text to which it applies. What do you mean by "the run of text to which it applies"? Is it not the case that ordinals are required to be used consistently through a story if they ar...

Re: Code Editor Font

The defaults are not practical. This looks like a bug. FontCreator 10.1 suffers from the same issue.

Re: Chaining Context: Ligatures following numerals

SHOCK ... HORROR :shock: :roll: Ordinals and Fractions don't play well together in many other fonts including professionally designed expensive fonts which really ought to know better !! Many of them turn all lower case text to superscript inappropriately. Yes. I took the trouble to write to the de...

Re: OpenType Features: Order of Precedence

If I use Ordinals, I will enable it as part of the Body Text paragraph style. This is the only practical method. Highlighting every occurrence of st, nd, rd, or th to enable the Ordinals feature makes it pointless adding the feature in the first place. One may as well just use Superscripts. If the O...

Yes. Still some issues to resolve. I updated it again, but 123/456 is currently still broken.

This is the latest version.

Re: OpenType Features: Order of Precedence

Oops. And the frac feature is...complicated. There are 13 chaining contexts. I believe I based it upon Tal Leming's Fraction Fever code. So while not an infinite arbitrary fraction feature, I doubt people will be using more than it can handle. I found this thread on TypeDrawers , which refers to Ta...

Because of the amount of work on figuring out what it should actually do, and how to program it.

I will move it back to the Feature Request forum.
