Vim Tips

1.I always wished that as a programmer , I should not waste my time in
 writing the trivial stuff, the one I require every time I sit to write the
 program. For example, while writing any C-program, we have the general
 format of #include<...> & then main() {  ... return 0 ; }
 What if every time I start writing the program, this format is ready for me
 ?? Well thats possible, atleast with "vim".

Create the standard format of the file you want , lets say at <~/format> is
 the path.

Now start vim : vim ,& then type , in command-mode ---> :r
 ~/format ,thats all , whatever is in the file <~/format> will be simply
 pasted .

I have created the file : <~/lic.c> , it contains the GNU GPL disclaimer.
 Now after I finish writing the program , I just have to say ( in command
 mode ) --> :r ~/lic.c , thats all, the license-terms get pasted .
 It looks like this :

2.As you might have noticed , the <~/lic.c> has the field --> LAST UPDATED
 :  , now to put the date & time here , go to that line, & in command mode
 ---> :r !date .

3.Well, if that didnt really raise your eyebrows, here's somemore . What is
 the best thing of the "terminal" ?? Yes, it "auto-completes" the commands
 by '\t' key. Now what if the same feature of "auto-completion" is present
 everywhere & not only in the "terminal" ?? Well thats possible, (again)
 atleast with "vim" .

Create a new <.vimrc> file in your home-folder . Say : vim .vimrc , at your
 home-folder & then copy paste this code( I found it on net ) :

        *function! Tab_Or_Complete()
          if col('.')>1 && strpart( getline('.'), col('.')-2, 3 ) =~ '^\w'
                  return "\"
             else
                         return "\"
                endif
         endfunction
          :inoremap =Tab_Or_Complete()
          :set dictionary="/usr/dict/words"
 *
 Pls be sure of the indentation ,everything has to be strictly indented . I
 dont know what exactly it is doing .
 Now vim will "auto-complete" any words you type , press '\t' for the same .
 Its indeed cool ........proud to be a "vimmer" !! ;)

4.Now whats next ?? Well, enough of vim. Recently I came to know of the
 command that can convert .pdf files to text-files, post-script files ,
 html-files & many more. Just type in the terminal & then you press
 '\t' twice to see all the options .
 Reading man pages is boring , so u may convert a lengthy man-page to a html
 file & get a nice look & feel to read it , I did it for "info flex" .
 Type : info flex > flex.odt . Now open flex.odt & get its pdf format , &
 then use command --> pdftohtml flex.pdf flex.html

How do I make changes to a package and capture them using ltib

1. Unpack the sources and apply all current patches:

./ltib -m prep -p u-boot

2. Edit/add files under rpm/BUILD/package/
3. Build the package with your changes:

./ltib -m scbuild -p u-boot

4. Once the package builds successfully, check the install phase:

./ltib -m scinstall -p u-boot

5. Test your package before committing the changes:

./ltib -m scdeploy -p u-boot

6. Repeat steps 2 -> 5 until you are satisfied with your results.
