- : Right. I thought that InstantTeX would do like other TeX-WYSIWYG-packages
- : which TeX in realtime. It simply does not. What it does is starting TeX
- : once in a while when you type. This works well with letters and other small
- : documents, but have you ever tried some _real work_, like a 50+ page document?
- :
-
- While I don't want to serve as an apologist for InstantTeX --- it's hardly
- a "completed" product since it violates virtually every NeXT convention
- for GUI, and it's pretty silly to compare the cost of IT, which is just
- a front end for the already bundled TeX, with a complete TeX installation
- like Textures --- I do think there are some things to be said in Linde's
- favor. Specifically, he did solve the question of getting the previewer to
- "reopen on current page" so that as you make changes to your file the
- previewer shows them to you, rather than going back to the beginning of
- the document.
-
- Also, the original Lightning TeXtures, as memory serves me, was not
- much better than IT. It bogged down very quickly once the document got
- to be 2-3 pages long. It's apparently improved a great deal since I
- saw that demo version (which was probably not on a good piece of hardware
- either, but I don't remember specifically) and according to the latest
- posts on comp.text.tex the new release **really** flies because BSR
- re-wrote the whole thing in some sort of fast Mac assembler code. I'll have
- to check it out some time :-)
-
- I ran the IT demo on a couple of different documents and found it worked
- reasonably well on fairly mathematical document of 5 pages. What's
- disappointing, in some sense, is how poorly it works on *short* documents.
- My NeXT has only 8 Mb, and if you have WM, Edit, Stuart, TeXview and a
- couple other things going the disc churns and churns re-loading TeX every
- second or two. Drove me nuts! Worst of all, you get this behavior
- even for two lines of text!
-
- : I would actually believe in Dmitri writing a ramdisk for the NeXT. I have
- : waited long for something like that to hog up my memory. There are already
- : enough useful programs that use much memory, why not try one that does
- : nothing but add no free space?
- :
-
- More likely what will be needed is a complete rewriting of TeX so that it
- can sort of "sit there" waiting to be invoked again, as opposed to
- running like a batch job. Charlie Fletcher tells me there is a project
- of this nature going on at Berkeley (called VORTeX I believe) but it
- must be a pretty large restructuring of TeX, itself a highly complicated
- program. Maybe if you have enough RAM (and I know I want more, IT or no
- IT) and cna get some improvement from a RAMdisc (or some such thing) IT
- will work smoothly in RAM; but far more likely WYSIWYG TeX will take a
- major amount of rewriting Knuth's code.
-
- If having the near-instant feedback to your TeXing is important to you
- (and for the life of me I don't know why people find this attractive.
- I mean, do you re-compile your code every 30 seconds?) check out loTeX
- from the archives. Much simpler in aim than InstantTeX, but free and
- with some other useful features (and written by Derek Beatty, a great
- fellow!).
-
- Oh yeah, I agree heartily!! IT does have a GREAT Icon.
