beautifying my code

these changes give more legibility to code:

sed script to change:

  • if( -> if (
  • if....){ _> if...) {
  • }else -> } else
  • else{ -> else {
  • for( -> for (
  • for...){ -> for...) {

find . -type f -name "*.php" -exec sed -i -e 's/if(/if (/g' -e 's/if\(.*\)){/if\1) {/g' -e 's/for(/for (/g' -e 's/for\(.*\)){/for\1) {/g' -e 's/else{/else {/g' -e 's/}else/} else/g' {} \;

I had forgotten "foreach":

find . -type f -name "*.php" -exec sed -i -e 's/foreach(/foreach (/g' -e 's/foreach\(.*\)){/\1) {/g' {} \;





sed script to trim trailing spaces:

find . -type f -name "*.php" -exec sed -i 's/[ \t]*$//' {} \;



this may also be handy, to strip ^M characters:

Hi..to remove ^M, give the command :
sed -e 's/^M//g' filename
you will have to write the control-M as follows : first press control-V,then control-M,this will show the correct control-M on the command line.
For removing the linefeeds,try this :
sed -e 's/.$//g' filename
this will remove the last character from the line,which happens to be the line feed.
