[title={Lean and mean},
subtitle={\LUAMETATEX},
location={\ConTeXt\ meeting, September 2019},
author={Hans & Alan},
mp:title={\LUAMETATEX}]
\startdocument
\setupitemize[headintext]
\setupitemize[headstyle=bold]
\page \setupdocument[mp:subtitle={How it became}]
\startitemize
\starthead {interferences:}
\CONTEXT, plain \TEX\ and \LATEX\ all have different demands (we want to
experiment and move on and users pick up fast)
\stophead
\starthead {complexity:}
the source tree is way too complex as is the build (we only need \LUATEX)
\stophead
\starthead {distributions:}
no one can guarantee stability for \CONTEXT\ (being a minor player but
often a bit ahead)
\stophead
\starthead {annoyances:}
experimental codes leads to usage outside \CONTEXT\ and that triggers
complaints
\stophead
\starthead {motivation:}
running into folks who love to stress \quotation {huge bugs} and
\quotation {much instability} wastes energy
\stophead
\starthead {arguments:}
I got tired of \quotation {you need to support this because \unknown}
blabla
\stophead
\starthead {nagging:}
like \quotation {the manual \unknown} is becoming too tiresome, so best
keep experiments within the \CONTEXT\ bubble
\stophead
\stopitemize
\page \setupdocument[mp:subtitle={What it is}]
\startitemize
\starthead {simplification:}
we don't need all what is currently in the \LUATEX\ engine as we don't
use it
\stophead
\starthead {source:}
there is much less of it and we can get rid of \WEB\ artifacts
\stophead
\starthead {compilation:}
there was much more going on than was needed and only a few knew those
details
\stophead
\starthead {consistency:}
to guarantee consistency with \CONTEXT\ the source code will be part of
the source distribution (once I'm satisfied)
\stophead
\starthead {marketing:}
this way the relation with \CONTEXT\ and its user base is more clear
\stophead
\starthead {playground:}
we can move forward and experiment without the danger of running into
problems with non \CONTEXT\ users: \quotation {use it at your own risk}
\stophead
\starthead {possibilities:}
playing a bit more with the bits and pieces that are reponsible for most
(interfering) issues, like the the (asynchronous) page builder
\stophead
\stopitemize
\page \setupdocument[mp:subtitle={Implications}]
\startitemize
\starthead {binary:}
there is only one relatively small binary needed (that does all things
needed)
\stophead
\starthead {code base:}
there comes an extra source tree, but it's small (compresses to around 2
MB)
\stophead
\starthead {user control:}
if needed users can compile the program so we're self contained
\stophead
\starthead {future safe:}
we can move forward and improve
\stophead
\starthead {modern:}
a code base with the latest \LUATEX, \MPLIB\ and \LUA
\stopitem
\starthead {side effect:}
we drop \LUAJIT\ as it doesn't keep up (and benefits are too small)
\stophead
\starthead {design:}
we have a better separation between the Knuthian front- and output format
driven backend
\stophead
\starthead {independent:}
there is no dependency on external libraries, we keep all we need in the
code base (we only use a few small third party libraries)
\stophead
\stopitemize
\page \setupdocument[mp:subtitle={A few notes}]
\startitemize
\starthead {hobyism}
we don't need to carry the burden of everything (unless paid for it's
only fun and users that drives development)
\stophead
\starthead {convenience:}
the faster compilation makes reworking and experimenting reasonable
\stophead
\starthead {stepwise:}
I take my time an do string stepswise because things should not break
without fast recovery
\stophead
\starthead {feelgood:}
this all fits well into the good old \TEX\ extension model
\stophead
\starthead {eventually:}
when proven useful we can always push code upstream into \LUATEX
\stophead
\stopitemize
\page \setupdocument[mp:subtitle={Bits and pieces}]
\startitemize
\starthead {original:}
the starting point is \LUATEX, original \WEB\ code, already \CWEB\ code
\stophead
\starthead {stability:}
after a initial stage \LUATEX\ was stepwise extended till version one
a few years ago
\stophead
\starthead {frozen:}
there were only a few changes after that but no real conceptual ones
\stophead
\starthead {engine:}
what is now called \LUAMETATEX\ is a reworked code base
\stophead
\starthead {graphics:}
also \MPLIB\ has been reworked a bit and some extensions were added
\stophead
\starthead {libraries:}
there are a few extra (small) helper libs, but all in the source tree
\stophead
\starthead {pplib:}
we already use the next version of pplib
\stophead
\starthead {pruning:}
and best of all, quite some not used code could go
\stophead
\stopitemize
\page \setupdocument[mp:subtitle={Some details}]
\startitemize
\starthead {source tree:}
the code base has been regrouped, globals became more local (work in
progress), header files were added
\stophead
\starthead {source files:}
there is hardly any font related code, languages were kept, and the
backend code is dropped: show files
\stophead
\starthead {libraries:}
a few libs were added and dropped: show some
\stophead
\starthead {cmake:}
compilation is different: work in progress
\stophead
\starthead {mkxl:}
there are new files in \CONTEXT: \type {driv}, \type {lpdf}, \type {.mkxl}
and expect more
\stophead
\starthead {binary:}
there is only one stub for all
\stophead
\stopitemize
{\infofont during presentation: show the source tree as well as the binary directory}
