[Level 1] Back to the last position in Vim

Everytime when we left Vim, and we have to use the arrow down from the first line,
is that possible to back to the last position when we re-open it?
You can add the configuration below in your .vimrc!

au BufReadPost * if line("'\"") > 0|if line("'\"") <= line("$")|exe("norm '\"")|else|exe "norm $"|endif|endif

Wish this helps.

[Level 2] Shell Interactive With Zenity Episode 5 -- list

Image
If you want to give a list for user to choose, you can use the option "--list". The command synopsis as below: SYNOPSIS      zenity  --list [--title=title] [--window-icon=path] [--width=width]    [--height=height] [--timeout=seconds] [--column=text] [--checklist]       [--radiolist] [--separator=character] [--multiple] [--editable] [--print-column=number] [--hide-column=number] Just like " --calendar ", if you press "ESC" key or click button "Cancel", the return code will be "1". If you select one option and click "OK", zenity will response the option and return the code will be "0".

[Level 2] iif in Python

If you want to implement iif in Python, please refer to the following sample code: #!/bin/env python def iif(b): return 'It\'s True' if b else 'It\'s False' print iif(True) print iif(False) And the following sample, guess what will you get! #!/bin/env python b = True print 'b: %s' % 'Ture' if b else 'False' b = False print 'b: %s' % 'Ture' if b else 'False' Result: $ ./iif.py b: Ture False The second result is "False", not "b: False". Why??? Because the prededence of string concatenation is higher than if. Therefore you need to use () to make it correct. #!/bin/env python b = True print 'b: %s' % 'Ture' if b else 'False' b = False print 'b: %s' % ('Ture' if b else 'False') Wish this helps. regards, Stanley Huang
