Rewrite-inactive works only when called from a macro. This macro lets me define a macro and also show the definition in one go: <assign|show|<macro|x|<surround|<arg|x>||<rewrite-inactive|<arg|x>|recurse*>>>>
I think the recurse* is wrong where I put it, it doesn't seem to matter what goes there Sam On Mon, May 28, 2012 at 5:29 AM, Sam Liddicott <s...@liddicott.com> wrote: > I've found that I can't un-render an inactive& block because <arg|x> is > rendered as x, in a different colour, and picking out the > with|...|color|brown|... is more hacky than I want to get. > > In scheme mode "arg" is emitted but so is lots of other text that is hard > to filter out. > > So I'm back to making render-inactive work > > Sam > > On Thu, May 24, 2012 at 8:25 AM, Sam Liddicott <s...@liddicott.com> wrote: > >> I thought I'd try implementing closures in texmacs macros instead. >> >> I want a macro that can be provided a list of variables and produce a new >> macro that is a "with" block of those variables, and then evaluates the >> parameters. >> >> The produced macro would be of this form (although possibly I would use >> eval instead of compound): >> <xmacro|x|<with|...|...|<quasi|<compound|<unquote*|<quote-arg|x>>>>>> >> >> It seems it would work as this example shows: >> <xmacro|x|<with|a|AHA|<quasi|<compound|<unquote*|<quote-arg|x>>>>>> >> >> The producing macro must fill in ... according to the arguments it is >> passed, indicating the variables and their values to be preserved. >> >> My first attempt at the constructing macro is: >> >> <assign|enclose|<xmacro|w|<quasi|<xmacro|x|<quasi|<with|<unquote*|<quote-arg|w>>|<compound|<unquote*|<quote-arg|x>>>>>>>>> >> >> Note the nested quasi.
