Hi, I uploaded a new beta. The most important issues are the following: (1) Table I fixed a few things and there is limit color support \VL[10] rule ten times wider than normal \VL[red] red rule \VL[red,10] both The same applies to \HL and \DL, but with \DL the first argument hs the number of spans, so we can have: \DL[2,red,10]. (2) Buffers and typing This whole bunch has been cleaned up and pretty printing has been redone. The \type command accepts an optional argument with settings. as does \starttyping, \typebuffer and \typefile (and the defined variants). The interface for defining visualizers might change a bit but I'm getting there. There is a chapter on it in the cld manual. In principle one can provide arbitrary manipulators, think of: \startluacode local function parser(s) local s = string.gsub(s,"show","demonstrate") local s = string.gsub(s,"'re"," are") context(s) end visualizers.register("MyThing", { parser = parser }) \stopluacode \starttyping[option=MyThing,color=darkred,style=] This is just some text to show what we can do with this mechanism. In spite of what you might think we're not bound to verbose text. \stoptyping \startbuffer[demo] This is just some text to show what we can do with this mechanism. In spite of what you might think we're not bound to verbose text. \stopbuffer \processbuffer[demo][option=MyThing] There are only a few visualizers built in: TEX, MP, LUA, XML and PARSED-XML. There is also PARSED-LUA but that's for Luigi and me to play with first. Colors and fonts might change and are set up differently now, see v-*.mkiv files. (3) MkVI (or: moving on) Say that you have a file test.mkvi that has the following code: \def\TestOne[#1]% {this is: #1} \def\TestTwo#some% {this is: #some} \def\TestThree[#whatever][#more]% {this is: #more and #whatever} \def\TestFour[#one]#two% {\def\TestFive[#alpha][#one]% {#one, #two, #alpha}} \starttexdefinition TestSix #oeps here: #oeps \stoptexdefinition \starttext \startlines \TestOne [one] \TestTwo {one} \TestThree[one][two] \TestFour [one]{two} \TestFive [one][two] \TestSix {one} \stoplines \stoptext This will work out ok, in spite of the not so texy hash usage. This is an experimental feature and only meant for developers to play with. % macros=mkvi as top line also works. Files like that are preprocessed before they are passed to tex. (I'm considering permitting spaces before and after #whatever in the definition line.) More preprocessor features might show up. Of course the limitation of 9 arguments still applies.
