Re: Missing output from echo command ?

Here is a test file and test instructions.
I am including the file in-line between lines of =============
delimiters.

After you extract the test file, you need to clean it up, as the mails
modify some content.
1. You need to remove the ' ' blank inserted in each 'From - ...'
line. :g/^ From - /s/^ // should take care of that.
2. You need to remove the null lines inserted right after the
'X-Mozila-Keys: ...' lines.
:g/^X-Mozilla-Keys: / .+1d should take care of that.

Now you should be ready to test.
I am on an Intel cpu, MS WIN 7 x 64 ultimate system, with (SP1).
My VIM is an unmodified installation of 7.3 as downloaded from vim.org.
I have stored the test file as t13.txt on my desktop
I start the edit by right clicking on the t13.txt icon and selecting
edit with vim.
1. :set number
2. :set so=999
3. :hi Visual guibg=#bbbbbb
4. :1
5. : let ln = 999 | echo ln | let ln = search('^From - ','W') | echo ln
As outcome I get:
999
2
and the cursor moves to line 2
6. Repeat step 5 by pressing : up-arrow and enter.
As outcome I get:
the cursor moves to line 69
(???). I expected.
999
69
and the cursor to move to line 69
7. Repeat step 6. and keep repeating.

Now you can play with your own variations.

If they're not reproducible, we may have trouble helping!

That must be missing something. Should there be 'search' before those
parentheses?

Mmm. This kind of thing is working for me. But if it's stopping working
at some point, we need to try to figure out what makes it stop.

That's correct, isn't it? There is no "From - " after line 350.

Can you try to make a small test case with a particular file and exact
steps which
can be followed to demonstrate the problem?

Ben.

Maybe do a bit more preprocessing of your files before sending them to
diff, making the first line with any given timestamp unique so diff
'synchronises' on those. A little loop like this after your :s command
might do the trick (if it isn't too slow).

I like vim help style, it has toc, tag support, nice alignment.

I know the syntax used in vim help, but I'm curious how the author to
generate toc, indent, align the whole help?
