20 years ago, I only had a dot-matrix printer, and TeX isn't really set up to deal with extremely limited positioning granularity. Certainly everything I've written in the last 15 years has been in TeX unless it's been in HTML or something which renders to HTML. But TeX can actually be kind of problematic: you have to modify the file in order to avoid generating recto and verso pages, which are inappropriate for e-readers (or, really, any presentation form which doesn't involve dead trees). And TeX documents actually often make a lot of assumptions about the form of the result which means that there isn't machine-readable available to produce other presentation reasonably.
(Not to mention that building TeX requires implementations of at least two language dialects (WEB and \ph) which aren't used for anything else on any modern system; it's easier to make an emulator for the computers that Wordperfect ran on than to make a compiler able to build TeX, although people have done both.)

Most Linux distributions provide a TeX package. I believe it is build using a portable C implementation of WEB (web2c), which is a source to source translator. So just C is required for that part. Browsing the READMEs of a recent TeX for Linux implementation (http://www.tug.org/svn/texlive/trunk/Build/) there certainly are also other dependencies for building and auxiliary programs, but that is stuff that typical Linux implementations already provide. Of course bootstrapping TeX for a very different computer and OS from scratch would be a lot of work, but at least it is possible, thanks to the good documentation of teX and its source.

web2c (plus a C compiler) is an implementation of WEB and \ph, and is of comparable portability and complexity to dosbox, which will run your old word processors. TeX's source does contain a lot of documentation about the expected Pascal dialect and the preprocessor; but there's even more documentation about the x86 and DOS. Your old DOS programs don't come with an extensive description of the platform they run on, but they're also not the only things that use that platform, so they don't have to.
On text documents Posted May 11, 2012 17:07 UTC (Fri) by eru (subscriber, #2753) [Link] Still have to disagree here. I'm pretty sure I could port web2c to a new platform in an evening or two, provide it has a decent ANSI C compiler (which is now a very common piece of infrastructure and can legitimately be assumed). Porting DOSBOX would be a much larger task, unless the new target is very similar to some of the existing ones. Yes, there is more documentation about x86 and DOS, because a lot more is needed to describe the complicated and ugly interface, and it is still incomplete...I have found bugs in DOSBOX, which I currently use to support some legacy cross-compilation tools at my workplace. Also used DOSEMU+FreeDOS for the same task, and found it has some different bugs... I could work around the problems for the limited set of programs that were needed. But the fact is the only thing that is completely MS-DOS compatible for all programs still is the original MS-DOS.

Although the CURRENT WordPerfect file format is about 18 years old (it was created, as a result of MS breaking the old 5 format) in 1994.
To the best of my knowledge, WordPerfect files are both backwards AND forwards compatible between v6.0 (released in 1994 as I said) and the latest version.
So incompatibility like this is a deliberate or accidental vendor choice, not something that is inevitable ...
Cheers,

What influence has MS had on Wordperfect, which, like Wordstar, was something entirely different from MS Word and Winword.
