Ambiguity in font tags - Githubissues

dr-scsi commented 2 years ago

Hi all,

first of all, many thanks for developing and providing these fonts. I downloaded the latest release source-serif-4.004.zip and ran autoinst tool on the OTF-fonts. In case you're not familiar with this tool, it produces all the files you need to use OTF-fonts with traditional TeX engines like pdfTeX.

The program doesn't succeed with this message:

[ERROR]     I failed to parse all fonts in a unique way;
            presumably some fonts have unusual widths, weights or shapes.

            Try one of the following:
            -   Run 'autoinst' on a smaller set of fonts,
                omitting the ones that weren't parsed correctly;
            -   Add the missing widths, weights or shapes to the tables
                'WIDTH', 'WEIGHT' or 'SHAPE' in the source code;

The fonts are not unambiguous based on the fonts tags (I'm not sure if tag it the correct word in this case). It there a chance to update the files in order to make them unique based on provided information per font?

With “font tags” I assume you mean the style name, such as Bold Italic? The typeface family is split up into various sub-families, such Source Serif 4 Caption, Source Serif 4 Text (name omitted), Source Serif 4 Display, etc. Can your parsing workflow take this into account?

dr-scsi commented 2 years ago

With tags, I meant the key value pairs like Weight=semibold. I think I will drop the author of autoinst a line if he can also have a look at this issue. After your comment, I ran otfinfo -a SourceSerif4SmText-Regular.otf to get the family name and the program returns Source Serif 4 SmText. So maybe the problem is somewhere else. I will report back. Thanks.

I contacted the author of autoinst and it seems this issue is related to it and not to the fonts. I close this issue. Many thanks for your efforts.

Thanks for the note – no problem :-)
