Using gcc I can remove comments and unwanted blank lines, but I want to reduce a size of file also, is there any options in gcc or any other tool to do so
At present I do like this
gcc -fpreprocessed -dD -E -P source_code.c > source_code_comments_removed.c
Here is scenario assume that this is my source_code.c
#include <stdio.h>
main()
{
// declar variable i
int i=0;
/* multiline comment
for loop
demo stuff
*/
for(i=1; i<=5; i++)
{
// just print something
printf("Hello %d \n",i);
}
}
I want to minify like this, removed comments and blank lines
#include <stdio.h>
main(){int i=0;for(i=1; i<=5; i++){printf("Hello %d \n",i);}}
Note : I am on Linux please don't suggest any windows based solution
sed -rb 's/ {6}//g' main.c |
sed -rb 's/\/\/.*$//g' |
tr -d '\n' |
sed -rb 's/\/\*.*\*\///g' |
sed -rb 's/(#include.*>)/\1\n/g'
will give you:
#include <stdio.h>
main(){int i=0;for(i=1; i<=5; i++){printf("Hello %d \n",i);}}
However, as stated in the in the comments, this doesn't make much sense and will not reduce the size of your compiled object file!
