Dear all, I am thinking about moving from LaTeX to ConTeXt. But there is one thing make this particularly difficult. That is the microtype LaTeX package. More specifically I have the following questions (assuming I will use MKIV and luatex) 1. I understand that ConTeXt can do margin kerning and font expansion, but is there a way to setup a configuration file for each font set. Like the mt-foo.cfg file for font family foo when using microtype in latex. 2. Is there a way to do letterspace in ConTeXt. I understand there is a command called \stretched. But what I want is the feature like the tracking option in microtype package, which can automatically letterspace all small caps. Moreover is there a way to define new sets of fonts for letterspace. For example I defined a new font shape called \capshape, which use case tags of OpenType, and I want to use letterspace this shape with certain amount all the time because I am not satisfied with the space provided by the cpsp tag of OpenType. I am sorry for using and LaTeX terminology. I haven't start learning ConTeXt at all at this stage. I want to first know if it provide all the features I need before I spend my time on learning a new language.

you can define additional sets indeed an dpass the defined set as value to the protrusion and expansion features

i have no clue what microtype does (nor time to look into it) but you can just define a command that switches the font and enables intercharacter spacing, something \definecharacterkerning[mykerning] \setupcharacterkerning[mykerning][\c!factor=.125] \def\MySc {\groupedcommand {\sc\setcharacterkerning[mykerning]} {}} 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 -----------------------------------------------------------------

Thanks for all your replies. They helps a lot. As I can see now ConTeXt is indeed a far more advanced system than LaTeX. But I have one more query. Where can I find the documents. When following these replies and some other messages in the list, I find some commands not documented in the Manual or Reference Manual. In LaTeX, all commands are detailed documented in source2e.tex, in TeX, The TeXBook explains everything. So in ConTeXt, where can I find such detailed documents. I tried the documented source, but it is more like a PDF version or source with only a little documentation. On Mar 25, 2010, at 10:42 PM, Hans Hagen wrote:

as most of the functrionality does not change you can use older docs (website, wiki etc) for most cases newer things i.e. introduced in mkiv using luatex are described in for instance mk.pdf and articles of course the wiki is a good source as well 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 -----------------------------------------------------------------
