syntax/man.vim: manSubHeading is a bit too general?
The manSubHeading is defined as
syn match manSubHeading ^\s\{3\}[a-z][a-z ]*[a-z]$
This will, however, match more lines than I think is intended. It
will, for example, match the line
\t returns are what are recorded and compared with the data git keeps
where \t is a horizontal tabulation. I'm guessing that the actual
regex should be
^ \{3\}[a-z][a-z ]*[a-z]$
but I'm not sure; I haven't been able to find a reference for the
display of manual pages.
Anyone have any insight into this issue?

I suggest bringing up syntax highlighting issues for a specific filetype
with the syntax highlighting file's maintainer.
In this case, by looking at syntax/man.vim, its: Gautam H. Mudunuri
gmudunur AT informatica.com.

I hope nobody minds if I take this opportunity to ask a question about
vim's pattern matching.
After reading |pattern| I wonder if the following is more efficient:
syn match manSubHeading '^ \{3\}\l\l\?\l$'
Taken from |pattern|:
- Matching with a collection can be slow, because each character in
the text has to be compared with each character in the collection.
Use one of the other atoms above when possible. Example: \d is
much faster than [0-9] and matches the same characters
Do people find this to make a different for moderate file sizes, e.g.
the man page for 'less' being ~2000 lines?

Yes, and it may be more correct as well, at least in the first and
last instance. However, the second part may also contain a space, so
\l isn't correct there; and I don't know where you get that \? from.
This is the correct pattern:
^ \{3}\l[[:alpha:] ]*\l$
(I also noticed that the apparently accepted \{m\} is being used in
this file instead of the documented \{m})
One can of course ask oneself if a subsection heading must consist of
at least two letters. I'm guessing that the intent was to force the
line to end with a non-space:
^ \{3}\l\%([[:alpha:] ]*\l\)\=$
In fact, I'd prefer it be written as
^ \{3}\a\%([[:alpha:] ]*\a\)\=$
as 'syn case ignore' is on, \l and \a will be the same. However, \a
meshes better with [:alpha:] and may, depending on how all this is
implemented, be a miniscule amount faster.

how to delete all occur of a character

Re: how to delete all occur of a character
vim file1 file2 :argdo %s/\//gCR :xaCR Well, better do it this way: :argdo %s/\//g | updateCR Then vim will write only if there were any changes in the file.

Re: how to delete all occur of a character
i have a file ( actually a group of them ) and i need to delete the quotation marks in each file, i am sure that vim has a tool for this. For a single file, you want to use :%s///g For multiple files, you might want: :set hidden :argdo %s///g (review your changes) :wall (to write all the changes). If they're funky windows quotes, you may have to copypaste them, perhaps using control-R followed by whichever register holds the copied quote (either an asterisk/plus-sign for the system clipboard, or the double-quote register). You can read more at :help :s :help i_CTRL-R :help registers Hope this helps, -tim
delete buffer questions
I need som things explained about the automatic delete buffers 1-9. When I delete rows using dd the deleted text is put in the default buffer, using dd again will put it in 1 and so on. But if I use another kind of deletion like dw, I couldnt fetch it from the buffers 1-9, only from the first unnamed buffer. Why is this so and which kind of delete operations are supported in the delete buffers? -- View this message in context: http://www.nabble.com/delete-buffer-questions-tf3548826.html#a9907181 Sent from the Vim - General mailing list archive at Nabble.com.
Re: delete buffer questions
When I delete rows using dd the deleted text is put in the default buffer, using dd again will put it in 1 and so on. But if I use another kind of deletion like dw, I couldnt fetch it from the buffers 1-9, only from the first unnamed buffer. For future reference, these are registers rather than buffers (a different concept, and using precise terminology can help folks on the list in their replies) From :help quote_number Numbered register 1 contains the text deleted by the most recent delete or change command, unless the command specified another register or the text is less than one line (the small delete register is used then). The small-delete register is - holds deletions when they're smaller than a line (unless it was covered by the fairly lengthy list of exceptions covered in the quote_number help) Why is this so and which kind of delete operations are supported in the delete buffers? I'm not sure why some things are arbitrarily chosen as small deletes, but any motion can be used with a delete. If you want to ensure that the deleted contents go into the trickle-down list of registers, you can prefix your deletion with an explicit register: 1dw This will force a trickle-down of the current history of deletions for any such deletion. Odd things happen if you specify the middle of your history, such as 4dw as it ends up in register #5 instead of #4 because of the nature of the trickle-down (or rather it gets put in #4, the trickle-down occurs and it also gets put in #1 so the formerly#4 is now in #5). Just a few musings on the peculiarties of them. I don't usually use them unless I have previously used :reg to figure out which one I want...my memory isn't quite that good :) HTH, -tim

Not in my tool chain; I get tabs.

If you updated vim to 7.0 using apt-get, perhpas you could check if the runtimepath also be old in your vimrc. for example, replaced /usr/share/vim/vim64 to /usr/share/vim/vim70 李长青 wrote: hi,all: I am new to Vim,I am using Vim7.0 now,and it has no Syntax even when I set Syntax on,It stell has no syntax hignlighting,why?
