Asterisks are added automatically by the OCR, that is written in Lisp (or inLab Scheme). The asterisks control the outline in something lawyers call org-mode. They use tabs and shift tabs to close the outline, and have a fast overview of the document.

It does not have schedules, calendars, deadlines, etc. Latex sources seems to be much slower in Vim, and often freezes Vim. In fact, I noticed that Vim becomes so slow that people types faster than Vim deals with the syntax coloring. First question: How to make Vim faster?

Any dialect if Lisp will do. People who wrote the scripts said that they can convert everything to Racket, Common Lisp, etc. I read somewhere that Vim accepts scripting in almost any language: Python, Ruby, and Racket.

People says that Vim is better than Emacs, and that everybody uses Vim, etc. Therefore my friends decided to give Vim a chance. Audiatur et altera pars, lawyers say. In the context, it means: If there is a claim that Vim is better than Emacs, you should try Vim, before dismissing the claim. Therefore give examples, and explain how to install everything that need to be installed in order to make Vim faster.

To Marc Weber.

Thank you for your prompt answer. I am very impressed with your knowledge of the problem. I thought nobody heard about org-mode, and you came with an alternative :-)

1- Speed. I followed your recomendation of turning the syntax off, and it worked in the sense that Vim became faster.

:syn off

However, the syntax colors disappeared. I am sure that you expected that. You probably wanted to check whether the problem was with the syntax highlighting. As for the version, people are using the 7.4 version, that one installs with mercurial. Thus:

~/edt# hg clone https://vim.googlecode.com/hg/ vim

Then then they (the lawyers) compile it with:

./configure
make
sudo make install

I read in the site that one should also type:

hg pull
hg update

They have skipped this step.

2) I am glad to know that I can compile Vim with Racket. This solve the other problem too. I will start looking for documentation on how to do it. I would appreciate if somebody know how to do it, and could provide a command line to build vim with Racket. Is it as easy as building vim with Python?
