Take care of TeX!

This is a TeX kernel system providing what everything is based upon: Donald E. Knuth's Digital Typography system; with some useful additions.

This system includes, of course, METAFONT and TeX; but auxiliaries are also included.

All the programs (latest published version) are included here.

In addition, other programs linked to Tomas Rokicki's dvi to PostScript driver (dvips(1)) are added. Oren Patashnik's BibTeX (0.99d) is here too; John Hobby's MetaPost is included; The NTS team e-TeX (now the default engine for LaTeX) is here and D.E. Knuth and Silvio Levy' CWEB are here as well as a packaging system.

The fact that kerTeX, the kernel, is associated with a limited subset of utilities, for the main part POSIX.2 ones, makes kerTeX a system that is handling itself its extensions (packages). The result, is that whatever hosting system kerTeX is installed on (Plan9, *BSD, the various Linuces (including Android), MacOsX or Windows), one and only one kerTeX package is written. All the packages (optional) proposed below are hence installable on all kerTeX installations.

This is the 0.9999999.0 version (for kerTeX_T) that includes all the latest version of the programs and adds the X11 support for METAFONT online graphics output.

The main major addition was the Android support by the compilation framework R.I.S.K. (Thanks! go once more to Antonio Olivares for wanting to install kerTeX on Android with termux, reporting and testing until the support was right.)

The planning is:

Quick install

The compilation framework R.I.S.K. allows all the possibilities, including cross-compilation. For an extensive number of OSes, the parameters files are included, and these parameters are only sh(1) variables. It is easy to extend the support to a new system (this has been done for Android recently).

In theory, since the kernel depends only on a libc, almost all the systems can be supported.

The unprivileged (non root) installation is supported as well.

But in the most common case, i.e. compilation and installation on the very same OS and architecture, things can be simplified and for this, scripts have been written for a quick install.

There is one script for Unix like systems (this includes, at the moment, Windows since it is only supported via Interix, Cygwin, Ubuntu etc.) and the other for Plan9 : get_mk_install.rc.

You have only to download and execute the script, for Unix:
sh ./
or for Plan 9:
rc ./get_mk_install.rc
and just let the script guide you.

In order for R.I.S.K. to be able to run, it needs a limited subset of POSIX.2 utilities. For downloading, a FTP/HTTP retriever is also needed (like ftp(1), lftp(1) or hget(1)). Under Plan9 or the *BSD, these utilities are provided by the system. Under the Linuces variations, it depends. You may have to add them (they are common so there are packages for them)—if a utility is missing, R.I.S.K. will stop and tell you so.

As an example, under Android termux, after installing termux of course, you will need the following (thanks to Antonio Olivares for the informations):

For running kerTeX, since at the moment the only dvi driver is Tomas Rokicki's dvips(1), if you want to display the result, you will have to install ghostscript as well.

Finally, under Android termux, the installation is an unprivileged one (and the principle applies to every unprivileged installation), and you will need to adjust the PATH, here under ˜/.bash_profile so that which_kertex can be found (as well as the kerTeX programs). If you have not changed the default dir for Android/termux, that is home/bin :
export PATH

More about the description, the installation and the running in the README.


KerTeX passes the TRAP (METAFONT), TRIP (TeX), TWIST (MetaPost) and ETRIP (e-TeX) controls and so is conform to the licences whose extract is given here for TeX (see the sources for the whole details):

[TeX] This program is copyright (C) 1982 by D. E. Knuth; all rights are reserved. Copying of this file is authorized only if (1) you are D. E. Knuth, or if (2) you make absolutely no changes to your copy. (The WEB system provides for alterations via an auxiliary file; the master file should stay intact.) See Appendix H of the WEB manual for hints on how to install this program. And see Appendix A of the TRIP manual for details about how to validate it. TeX is a trademark of the American Mathematical Society.
[METAFONT] This program is copyright (C) 1984 by D. E. Knuth; all rights are reserved. Copying of this file is authorized only if (1) you are D. E. Knuth, or if (2) you make absolutely no changes to your copy. (The WEB system provides for alterations via an auxiliary file; the master file should stay intact.) In other words, METAFONT is under essentially the same ground rules as TeX. METAFONT is a trademark of Addison-Wesley Publishing Company.

Other programs or data, compiled or added from sources external to kerTeX_T, all have licences compatibles with kerTeX one and the use done. (See their sources for more details.)

The risk_comp, kertex_M and kertex_T licences, packages made by Thierry Laronde, are of a BSD type with simplified recognition (``publicity'') claused. See the table below for downloads.

KerTeX has been derived, for a significant part, from Web2C version 5.0C (public domain, 1990). But it is also significantly different. The work of the following authors has been used (extract from the licences):


Both the sources and the patches are gzip compressed and are provided with a GNUpg detached signature so that you can ensure that what you have actually retrieved matches what the release manager has put online.

At the moment, the release manager is Thierry LARONDE, and you can retrieve his public key from the keyserver
