* issue with italic correction (again) @ 2019-06-25 19:42 Pablo Rodriguez 2019-06-25 20:08 ` Taco Hoekwater 0 siblings, 1 reply; 5+ messages in thread From: Pablo Rodriguez @ 2019-06-25 19:42 UTC (permalink / raw) To: mailing list for ConTeXt users Dear list, [sorry for insisting, but I have the impression that the previous version of this message went unnoticed.] I have the following sample: \def\DesiredFont{TeX Gyre Termes} \definefontfeature[italic][itlc=yes,textitalics=yes] \setupitaliccorrection[global, always] \definefontfamily [mainface] [rm] [\DesiredFont] \definefontfamily [mainface_corrected] [rm] [\DesiredFont] [features={italic}] \setupbodyfont[mainface] \setupitaliccorrection[global,always] \starttext \startbuffer[chars] \startTEXpage[offset=1em] \dorecurse{26} {\setupbodyfont[mainface]% [{\em \recurselevel}] [{\em \characters{\recurselevel}}] [{\em \Characters{\recurselevel}}] ({\em \characters{\recurselevel}}) ({\em \Characters{\recurselevel}}) \hfill \setupbodyfont[mainface_corrected] [{\em \recurselevel}] [{\em \characters{\recurselevel}}] [{\em \Characters{\recurselevel}}] ({\em \characters{\recurselevel}}) ({\em \Characters{\recurselevel}}) \par} \stopTEXpage \stopbuffer \getbuffer[chars] \def\DesiredFont{TeX Gyre Pagella} \getbuffer[chars] \stoptext This shows that sequences such as ({\em f}) are corrected with the closing parenthesis, but not with the opening one. Wouldn’t it be possible that italic correction could be enabled also before the italic glyph(s)? BTW, I wonder why the second definition of \DesiredFont doesn’t change the font for the buffer used after it.

Using \switchtobodyfont instead of \setupbodyfont for all except the first call should help. You may need to add a \usebodyfont[mainface_corrected] as well (in the setup block). I cannot actually test right now, on a mobile device...

I’m afraid that I cannot make it work. I guess I must be doing something wrong. I’d like to know which are the differences among \setupbodyfont, \switchtobodyfont and \usebodyfont.

No, it is not you. The problem is that \definefontfamily always expands its arguments completely, so by the time you call the body font up, it will already contain the actual font name instead of the macro \DefinedFont. (I had to test that for myself first) Also, it seems that \definefontfamily does not like redefinitions. (I had to test that for myself as well) > > I’d like to know which are the differences among \setupbodyfont, > \switchtobodyfont and \usebodyfont. Generally, you use \setupbodyfont exactly once, in the setup area. This sets up the fonts for the whole document, and it also sets up some values for the ‘global environment’ (various internals use the body font size, for instance). If you do not call \setupbodyfont yourself, then ConTeXt will do an implicit \setupbodyfont[modern,12pt] at the \starttext command, just to make sure there is a valid body font defined. If you want to use other body font definitions as well, you can use \usebodyfont[mainface_corrected] % etc. which temporarily switches to the specified body font set, but immediately switches back to whatever was active before. It exists mostly for cosmetic reasons. ;) When you want to switch to any of the preloaded body font sets inside your document, you normally would use \switchtobodyfont. This only affects the document text, not headers and footers, and does also not do the global setup. You could use \setupbodyfont instead, but \switchtobodyfont is usually what you want, and it is also a bit faster. Anyway, about your example: here is a version that does do the switching: \definefontfeature[italic][itlc=yes,textitalics=yes] \setupitaliccorrection[global, always] \starttext \startbuffer[chars] \definefontfamily [mainface\DesiredFont] [rm] [\DesiredFont] \definefontfamily [mainface_corrected\DesiredFont] [rm] [\DesiredFont] [features={italic}] \startTEXpage[offset=1em] \dorecurse{26} {\switchtobodyfont[mainface\DesiredFont]% [{\em \recurselevel}] [{\em \characters{\recurselevel}}] [{\em \Characters{\recurselevel}}] ({\em \characters{\recurselevel}}) ({\em \Characters{\recurselevel}}) \hfill \switchtobodyfont[mainface_corrected\DesiredFont] [{\em \recurselevel}] [{\em \characters{\recurselevel}}] [{\em \Characters{\recurselevel}}] ({\em \characters{\recurselevel}}) ({\em \Characters{\recurselevel}}) \par} \stopTEXpage \stopbuffer \def\DesiredFont{TeX Gyre Termes} \getbuffer[chars] \def\DesiredFont{TeX Gyre Pagella} \getbuffer[chars] \stoptext Best wishes, Taco ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 5+ messages in thread

I really appreciate to understand how the body font is handled in ConTeXt. As you wrote, \setupbodyfont is only needed once. I don’t use other body font command in almost any document. This is a special case, required to show the difference in italic correction.
