I have a first "operational" version of my lpeg-based xml pretty

A remark:
I'm currently replacing the current pretty printing interface
and the new infrastructure is based on lpeg (which was not around when I
did the first implementation). This is part of the work on cld (where
verbatim has its own niche).
As I think that there are different demands for pretty printing it will
be easier for users to plug in code. Also, there will be less tex code
involved as the cld interface is used at the lua end, i.e. there are
regular lua functions for dealing with it.
As you already are playing with pretty printing I'm sure that you will
be able to plug in your code. But, naming is important and may not
override the built in methods.
By default there will be the following pretty printers:
- v-tex
- v-metapost
- v-lua
- v-xml
These are dumb variants, insensitive for syntax errors which is handy
for manuals. In addition there will be:
- v-lua-plus (name can change)
- v-xml-plus (name can change)
where the first one replaces the cdx code now used for documenting (so
this targets at luigi) and can mix lua code with documentation. The
second one is used by myself when documenting xml code and uses the
built in parser.
Now, additional pretty printers can be plugged in as well (there is a
register function for that) and can have names not starting with v-.
Even better, they can be regular user modules, so in your case
u-pretty-ra-xml.tex
or so will do. There are already some basic pretty lpeg helpers that
will take care of (visualizing) spacing, lines, and more. In principle
one can also mix pretty printers (so, lua code inside tex code and
alike).
It also means that other pret-* code has to be adapted (and ends up in
the u-pretty-* namespace).
Sorry for the inconvenience. More later.
