As many have discovered, there is a annoying bug in the Tcl version shipped with Debian/Ubuntu (which may not be the case with the latest Ubuntu - I am still one release behind on my day-to-day laptop). In any case, here is my fix:

In the file /usr/share/tkcvs/cvs.tcl search for the line "set juliandate [clock scan $date -gmt yes]" (around line number 143).

Add a line just before it, so that your code now reads:

      } else {
        set date [concat [lindex $date 0] [lindex $date 1]]
        set juliandate [clock scan $date -gmt yes]

That's it. Restart tkcvs and all should work now.

Some might remember my earlier experiments in dynamic code execution in Perl. Here is a simple recipe to demonstrate a similar concept in Python:

 #!/usr/bin/python

 import new

 def importCode(code, name, add_to_sys_modules=False):
    # code can be any object containing code: a string, a file object, or
    # a compiled code object.  Returns a new module object initialized
    # by dynamically importing the given code, and optionally adds it
    # to sys.modules under the given name.
    #
    module = new.module(name)
    if add_to_sys_modules:
       import sys
       sys.modules[name] = module
    exec code in module.__dict__
    return module

 code = """
 def testFunc( ):
    print "spam!"
 class testClass(object):
    def testMethod(self):
       print "eggs!"
 """

 m = importCode( code, "test" )
 m.testFunc( )
 o = m.testClass( )
 o.testMethod( )

Hopefully you will find this useful. In theory you can now execute snippets of code from sources like databases and files. I think this has potential for some distributed processing framework :-)

Simple, really:

import sys
sys.path.append("/home/you/your_modules")

And that's it.

I could never figure how to grow/shrink vertical splits in Vim - sad, but true. It never really bothered me, as I rarely used vertical splits, but now that I know how to resize the windows, I used it more and more.

So, to grow/shrink the vertical split:

<ctrl>+W and '<' or '>'

That's it :-)

O - and I found a simple short way to toggle line numbers:

:se nu!
