While browsing through Don Knuth's publications on TeX, I was referred to the file
tripman.pdf on my MacTeX distribution. As TeXnicians may know, this file explains the purpose of the
TRIP test and how it is to be used, along with the provision of the source to the input files and the correct output. I decided (foolishly?) to try out the test for myself, which is where the issue begins.
I have two questions:
- In step 2 of Appendix A, how should I go about modifying
INITEXso that the parameters are set as specified there? I have heard of 'change files' which modify the output of
ctanglewithout changing the original
CWEBfile, but it is my understanding that such files cannot modify the behaviour of
UNIXexecutables. Without modifying the source of TeX, how can this be done?
- In step 4, should the version of
INITEXbeing run be the unmodified version or the modified version in step 2? I assume that, for debugging purposes, the modified version should be used, but I would just like to confirm.
Any further information regarding potential challenges in conducting this test would be very much appreciated. I am a frequent (though admittedly unskilled) user of LaTeX who has recently begun reading the works of Don Knuth on typesetting and typography and may need a little assistance in understanding such materials.
My machine is a Mac running TeXLive 2019 in the form of MacTeX. If any other required information is missing, please request them in the comments.
This is my first foray into TeX.SX, and so the quality of my questions may be subpar. I apologise for any faux pas I may have committed in the course of writing this question, and I welcome all suggestions as to how the above may be improved. Any suggestions as to appropriate tagging would be greatly appreciated. Please, be gentle.
