Hi,
So, for those who hesitate to check out lmtx, here is some information.
- In order to achieve long term stability context will use a lean and
mean variant of luatex (although for now context will keep running on
luatex too; i might drop support for luajittex). Eventually the source
code will be part of the context distribution so that one can always
compile a binary that matches an archived context version.
- This version also permits us to experiment (even very extreme) without
interupting the parent program luatex, which is now used by other macro
packages too and therefore needs to be frozen in functionality. Some
features might trickle back into luatex eventually (unless it breaks
compatibility).
- As a direct effect it means that context does a bit more: creating the
pdf file (already most is done anyway in mkiv), dealing with font
embedding, handling image inclusion, etc. For sure there can be issues
with that but it has run on my machine already for quite a while.
- It is hard to be conclusive about performance but for instance the
luatex manual processes a bit faster with lmtx as does the test suite. A
gain in performance on very demanding documents is also observed by Alan
and Thomas. Normally one can expect a similar performance. However, the
memory footprint could be a bit smaller.
- The current somewhat hybrid codebase of context will stepwise be
adapted so that at some point we can start experimenting with some
pending ideas. (Which is why i sometimes answer "later this year".)
Where can I find the C sources for the luametatex engine?
nowhere ... as i mentioned these will become part of the context
distribution around the ctx meeting (when we also have the compile
infrastructure ready)
what we offer now is an experimental test release
