== Part II: Additional VIM Tips added by WiKi Users ==

=== replace tabs with 2 spaces ===

 :1,$s/\('''^I'''\)/  /g 
note: the '''^I''' is the result of simply pressing the TAB key.  That is the escape code for a TAB.

=== tell vim to insert spaces when the tab key is pressed ===

 set expandtab
 set tabstop=2
 retab
note: the tabstop tells vim how many spaces to use for a tab, and the retab changes all the tabs you entered before turning on expandtab into spaces.

=== parameter in your text files telling vim how to render file ===

 vim: textwidth=80
note: put this at the bottom of the text file.  when you open the file in vim it will set the width to 80 columns for that file.

=== Disable automatic comment insertion ===

If wanted, auto commenting can be disabled for all files with:
 :set noautoindent | set nosmartindent | set nocindent 

Create a .vimrc for your shell and put the lines in like this
 set noautoindent
 set nosmartindent
 set nocindent 

or to Disable auto commenting just for paste operations temporarily while working in a file
 :set paste

=== Disable annoying bracket highlighting aka bracket match aka parentheses match ===
Using the ":syntax off" doesn't disable bracket match, such as you would see when working with HTML tags.  The problem is that the highlighting is terrible on some terminals such as Konsole.  To disable type
 :NoMatchParen
The  matchparen plugin has become enabled on your installation.  You can run the :NoMatchParen command to shut it off.  ":he matchparen" has instructions for how to disable it altogether.  You can also find out where 'showmatch' might be getting set by
setting the 'verbose' option to non-zero or using the ":verbose" command.  You can see ":he :set-verbose" for more info on that one.  Colors for the matching bracket or brace can be customized by adding to the .vimrc file.
 hi MatchParen cterm=none ctermbg=green ctermfg=blue
reference: [http://vim.1045645.n5.nabble.com/turning-off-showmatch-td1181954.html turning off showmatch]

=== Use vim as a HEX Editor ===
The vim editor does not have a HEX Edit mode, but can stream the buffer to an external program called xxd.

Open the file with the -b command line switch (''Binary mode. A few options will be set that makes it possible to edit a binary or executable file.'')

 vi -b binaryfile
Now stream the buffer to xxd from within vim
 :%!xxd
And when your done and want to exit the redirect
 :%!xxd -r
If you are at the command prompt you can display the hex output of a binary file simply by typing
 xxd binaryfile
This demonstrates how you are actually using xxd from within vim

When using vim as a HEX Editor remember to run the filter (:%!xxd to convert to hex, :%!xxd -r to convert back) and to convert back from hex before saving.  

===vim write with sudo trick===
Oops!  I opened a file in vim and made a bunch of edits not realizing that I do not have write permission to the file.  

[https://stackoverflow.com/questions/33366352/write-to-file-using-vim-when-sudo-privileges-needed Write to file using vim when sudo privileges needed]
 :w !sudo tee %
The !sudo tee part calls tee with administrator privileges.  

You can add this to your .vimrc to make this trick easy-to-use: just type :w!!.
 " Allow saving of files as sudo when I forgot to start vim using sudo.
 cmap w!! w !sudo tee > /dev/null %
