Which is as follows (run on all the python-lib*info* files and it'll
generate a file called "output"; rename that to ~/.vim/pyhelp.py)

import sys

docDict = {}

for file in sys.argv[1:]:
lines = open(file, "r").readlines()
for i in range(len(lines)):
line = lines[i].strip()
if line.startswith("`") and "(" in line and line.endswith("'"):
line = line[1:-1]
kv = line[0:line.find("(")]
j = i
while j < len(lines) and lines[j+1].startswith(" "):
j = j+1
line = line + " "+lines[j].strip()

if kv and kv not in docDict:
docDict[kv] = line

keys = docDict.keys()
keys.sort()
for k in keys:
print docDict[k]
open("output", "w").write("docDict="+`docDict`)

Vim scripting is nasty, but thankfully you don't really need to use it
any more. You can write all your code in python with just a one-line
hook to map it to a key.

On the topic, I did something like this that you might find handy; the
end result is that if you type
  a = myfunc(
then the arguments for myfunc are displayed in the status line.  If you
hit , then the full python docs (if any) are shown (I'm working on
having that show surrounding comments/docstrings for followed
functions, but that code is busted up something awful at the moment and
I haven't gone back to look at it).

It's a complete work in progress, it could be terribly broken.  I'll
try to get it more polished/functional and put it up on sourceforge or
somewhere.

The order of lookups for prototypes is as follows:
1. Try to follow tags; if there is a tag, grab the line in question
(and any further lines until reaching a ":").
2. Failing that, look in a help dictionary; I generated mine from the
info version of the Python docs, using a simple Python script.
3. Fail and show nothing.

A couple of caveats:
1. This uses the command area.  So you either need to turn off
"showmode" or set "cmdheight" to 2 or more; otherwise, the help text
will be clobbered immediately by the INSERT prompt.
2. The help dictionary is a dumb idea, it should be in a gdbm file or
something--right now it increases the size of a running gvim by 600KB
or so after the first time I use the help function (and that first
lookup is slow) because it's reading it a huge chunk of the vim docs.
3. The code abuses the preview window, which I don't care about because
I never use the preview window for anything else.  I would expect that
the user-visible effect of this will be to close any preview windows
you have open any time you type an open-paren.
4. It really works best in gvim; in a command-line vim it may recenter
your windows and have other jumpiness.  I tried for a while to figure
out a workaround and gave up.

That is very impressive. I saw a similar plugin which had a big drawback: 
it didn't know the object type you need context help for. E.g. it offers 
you help for the .split method even though you are dealing with an object 
which does not have this method assigned. The great advantage of the IDLE 
is that it really understands Python. So it knows about object types you 
work with. I'm curious how you handle that. Perhaps the python features in 
Vim have that built-in. But Vim scripting looked even evil for me... and 
I've been working with Perl for a decade. :)

Thanks for your contribution.

 Christoph

Hi Christoph,
Hi Vim users,

The last 5 days I´ve been working on a code-completion/calltips plugin for 
vim. It´s working pretty good but not finished yet. I will anounce the first 
beta version on this mailling list. I hope during the next week.

I recorded a swf-video so that you can take a look at the current status.
Link: http://www.tuxed.de/vimpst/video.tar.gz

Note that it is not necessary to generate symboltable files, etc. Everything 
is done "on demand". It is even possible to change the python implementation 
e.g. CPython, Jython, IronPython.

It is also possible to add some "special feature" interceptor. Currently this 
is working for SQLObject:
Lets say you have the class User and the attribute username is a alternate ID.
Then, the method User.byUsername("...") will always return a User object. 
vimpst checks this and provides a suitable help.

Regards,

Roman

Re: Pythonising the vim (e.g. syntax popups)

[Lonnie Princehouse]

There is a Python folding script, as someone already mentioned.  That
will help you track indentation, although it's not perfect (iirc, long
triple quoted strings cause folding malfunctions)

I don't know of any way to get dynamic help about functions, although
it seems like an ideal use of Vim's built-in Python interpreter and the
vim python module.

The PIDA IDE  claims
to be able to do something like this.  I have not used PIDA, but I too
am a vim zealot and I think wrapping vim with extra functionality is a
great idea, and I'll try it out when I get a chance.

You can set 'keywordprg' to something like "pydoc" to enable "K" to
pull up the help.  Its default setting is to open manpages for words
under the cursor.  I don't use it since I've got an interpreter shell
sitting in the corner of most virtual desktops -- doesn't everyone?

And ctags features are excessively prevalent in vim, and ctags works
fine with python IME.  You can create a tags file of your whole
python installation.

Matchit is a good one for %-matching:

Sure, that's builtin.  But Dmitry Vasiliev wrote some useful
enhancements:
http://www.vim.org/scripts/script.php?script_id=790
Note that you'll have to enable some variables in the macro.

That's kind of a nice idea, and it should be an easy one to write (but
I'm not volunteering).  You could write it (:h syntax-highlighting) or
maybe post a request to the vim mailing list <[EMAIL PROTECTED]>.

Otherwise, folding would be useful for this.  Pyfold might be helpful,
though I haven't tried it:
http://www.vim.org/scripts/script.php?script_id=781

I like the ruler idea!  Usually when I find myself straining to figure
out what level I'm at it means it's time to refactor.

Vim is my editor of choice, too.  I've even gone back to Vim from Eclipse.

I believe what you want are "tags."

http://www.vmunix.com/vim/tags.html

I have not tried these in Vim yet, although I did use etags with Emacs 
(before I discovered the miracle of Vim).

If you get context-sensitive help to work properly in Vim, please let me 
know!

Hi,
I am using gvim 6.4 which has Python colorising, and
The menu tools->folding->fold method->indent

:help folding
May give you more info.

Pythonising the vim (e.g. syntax popups)

[Christoph Haas]

Evening,

I'm an addicted vim user and don't really use the IDLE for anything more 
than calculations where I'm too lazy to start KCalc. But one feature is 
very pretty: the built-in help for function calls while you type. Like you 
enter...

var1,var2=mystring.split(
...and the IDLE shows me a popup saying...
"S.split([sep [,maxsplit]]) -> list of strings

Is there a decent way to get that help into vim? Or like showing docstrings 
or help that I get through pydoc on request? I've been working myself 
through a pile of vim macros/plugins but couldn't find even one which 
simplifies programming in Python. Further issues would be handling the 
indentation - maybe a plugin which syntax colors different levels of 
indentation so I don't have to use my plastic ruler on the screen. ;) 
Perhaps some more experienced Python/Vim users have a tip which macro sets 
help most here.

Thanks,
 Christoph
