Re: [NTG-pdftex] [ pdftex-Bugs-695 ] Confusion when changing kerning settings within a paragraph
I think it was not a good decision to introduce those new features, as they touch a very sensitive area of tex and it's hard to get them right. I wonder whether it is better to discard them all. Thanh On Wed, Nov 15, 2006 at 06:46:26AM +0530, noreply@sarovar.org wrote:

Initial Comment: Extra kerning now has this nasty, unreliable kind of paragraph scope, so that whether or not extra kerning will be applied depends on whether tex needs to hyphenate the paragraph, and whether a word contains a discretionary. (Same as for \pdfnoligatures [see discussion in feature req 385], for which this may be an acceptable limitation, since it has global scope, anyway. However, I don't consider it acceptable for the kerning feature. Think of language-dependant settings, for example.)

Hi Thanh,
I think it was not a good decision to introduce those new features, as they touch a very sensitive area of tex and it's hard to get them right. I wonder whether it is better to discard them all.
removing them is tricky since they may be in use already but don't spend to much time on fixing things that are hard to fix in current tex; once luatex is in a state where fontdata has no longer the global properties and where we can have more control over font related featurss, you can probably rewrite most of the code in a cleaner way Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Removing them all is probably too hard. And AFAIK all these new features are still undocumented, so we can treat them as experimental. Just try to not break existing features too much. :-) Best Martin
