lmtx
by Hans Hagen 02 Apr '19

02 Apr '19

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".) Anyway, it might not look like it, but it is a conceptual change in how context evolves.

Welcome to LMTX
by Hans Hagen 02 Apr '19

02 Apr '19

Hi all, After more than a decade of mkiv and luatex it's time to move on to a new stage. After all, nowadays a ten-year old program is considered to be really old, especially for those who consider a manual typeset three years ago as an indication of lack of progress. Therefore: welcome to lua(meta)tex 2.00 and context lmtx, the follow up on luatex and mkiv, if you dare. It has many deep-down changes but aims to be a simple evolution. The average user will probably not notice many differences but nevertheless, when you are in for something new, you can give it a try: http://www.pragma-ade.nl/install.htm Of course you should keep your current installation too. We're sure that there will be issues so when you run into unexpected surprises, you can blame us (and fall-back on the current Context beta and luatex). Of course with the proper mwe's (tex, metapost, lua, or a combination of these) we will try to solve them all, we have been testing. In due time more about this project will be revealed.

Hi, We have worked furiously all day kicking-out extra code, and are pleased to present a lean-and-mean version of luatex with your favorite ConTeXt. Same good taste but only half the calories and a new name: luametatex and ConTeXt LMTX. No more Mk-whatever, no more dependencies for we can now stand on our own. Of course, good-old luatex and MkIV (as well as MkII) will continue to coexist and be maintained. However, now you will be able to run ConTeXt lmtx on your smart thermostat or on your refrigerator for the Internet of Things - the dawn of a new era! Stay tuned, Alan and Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

Success! Yes, both executables must have interfered. Now it works with the long command as well with the short "context" one. Thank you Hans and Mojca! Rudolf

[Wiki] list of editors
by Henning Hraban Ramm 01 Apr '19

01 Apr '19

Ahoi! I reworked https://wiki.contextgarden.net/Text_Editors The split into "ConTeXt aware" and other editors didn’t make sense since they got mixed, editors that are Unicode-disabled we should just ignore, and the table had too many columns. If you know one of these applications better, please add the missing features. Additional features that *I* look for in an editor are e.g. project management (at least a directory tree view) and git client. But maybe that’s out of focus for that table.

announcement
by Hans Hagen 01 Apr '19

Hi, Nearly 20 years into the new millennium, we have decided to freeze the development of ConTeXt MkIV as well as luatex and are undertaking today a new project. A core team will as of today be working on the next version: luatex 2.0, a streamlined flavor of your favorite tool. Stay tuned for further information.
