\startitemize
\startitem it started out as \PDFTEX \FlushStep \stopitem
\startitem then got merged with \ALEPH \FlushStep \stopitem
\startitem but we left out the ugly bits of both \FlushStep \stopitem
\startitem it's exclusively \UTF-8 \FlushStep \stopitem
\startitem it's math machinery got extended with \OPENTYPE\ like features \FlushStep \stopitem
\startitem there are no fundamental extensions as it's impossible to agree in them \FlushStep \stopitem

\starttopic[title={The \LUA\ perspective}]
\startitemize
\startitem it just a \LUA\ engine \FlushStep \stopitem
\startitem it has some extra libraries on board \FlushStep \stopitem
\startitem you don't even have to use \TEX \FlushStep \stopitem
\startitem but there are hooks into the \TEX\ machinery \FlushStep \stopitem
\startitem and we can go further by loading libraries \FlushStep \stopitem

\starttopic[title={The hybrid perspective}]
\startitemize
\startitem we can extend \TEX\ using \LUA \FlushStep \stopitem
\startitem eventually everything will be opened up \FlushStep \stopitem
\startitem users never have to see any of that \FlushStep \stopitem
\startitem they can simply use \LUA\ for scripting and print results to \TEX \FlushStep \stopitem
\startitem but developers can go deep into the \TEX\ internals and mess around \FlushStep \stopitem
\startitem the average user will just depend on what a macro package will provide \FlushStep \stopitem

\starttopic[title={The complications}]
\startitemize
\startitem normally one wants a bit of infrastructure (management) \FlushStep \stopitem
\startitem and maybe a special user space, hidden from core extensions \FlushStep \stopitem
\startitem but history has tought that users can't be controlled that way \FlushStep \stopitem
\startitem so we stick to just providing the mechanisms \FlushStep \stopitem

\starttopic[title={The future}]
\startitemize
\startitem there are a couple of generic modules (derived from \CONTEXT) \FlushStep \stopitem
\startitem in principle I can make more generic modules \FlushStep \stopitem
\startitem that's after all the idea behind the (to be) \METATEX\ variant \FlushStep \stopitem
\startitem but does it really make sense as one still needs substantial subsystems \FlushStep \stopitem

\starttopic[title={This workshop}]
\startitemize
\startitem just using \LUA: it's what most users will do \FlushStep \stopitem
\startitem showing the hooks: it's what developers want to use \FlushStep \stopitem
\startitem answering questions: it's probably the most I can do \FlushStep \stopitem

\starttopic[title={Just plain}]
We need to make a format, like:
\starttyping
luatex --ini plain \dump
\stoptyping
\FlushStep
and can then run files with:
\starttyping
luatex --fmt=plain somefile.tex
\stoptyping
\FlushStep
This is a another way:
\starttyping
mtxrun --script plain --make --texformat=plain
\stoptyping
\FlushStep
with:
\starttyping
mtxrun --script plain --texformat=plain somefile.tex
\stoptyping
\FlushStep

\starttopic[title={A bit less plain}]
In order to profit from \OPENTYPE\ fonts:
\starttyping
mtxrun --script plain --make
\stoptyping
\FlushStep
with:
\starttyping
mtxrun --script plain somefile.tex
\stoptyping
\FlushStep
On windows you can copy \type {mtxrun.exe} to \type {plain.exe} and stick to:
\starttyping
plain --make
\stoptyping
\FlushStep
with:
\starttyping
plain somefile.tex
\stoptyping
