Script to fix comments into a file.

Just for the explanation:

• optional arguments are inside ()
• the value of an argument is inside <>

python3 main.py (-h) (-n) (-s) (-a) (-c <format_case>) (-e <excluded_words>) -t <comment_symbol> filename

• -t, --type: comment symbol (like // for C/C++, # for Python etc...) surrouned by '
  • Example: --type '#'
• filename: the file that needs comment formatting. MUST BE THE LAST ARGUMENT

Without value:

• -h, --help: prints the info message
• -n, --no-space: formats without space after the command symbol
  • Example: # this is a comment becomes #this is a comment
• -s, --spaces: removes extra spaces after comment symbol
  • Example:

    #     this   is a  comment

    becomes # this is a comment
• -a, --all: applies uppercase / lowercase to all words after comment symbol
  • Example: # THis Is A COMMent becomes # this is a comment or # THIS IS A COMMENT respecting excluded words

With value:

• -c, --case: u, upper or l, lower. Formatting type. Default: u
  • Example: # this is a comment becomes # This is a comment (without --all)
• -e, --exclude: string of words separated by , and surrounded by '
  • Example: --exclude 'NULL,ERROR'. # VALUE is NULL with -c lower -all becomes # value is NULL

test.c:

#include <stdio.h>

// main     function
int main() {
    //p poINTS to NULL
    int *p = NULL;
    //RETURNS 0
    return 0;
}

Comment formatting: python3 main.py -s -a -t '//' -c lower -e 'NULL' test.c

Result (new_test.c):

#include <stdio.h>

// main function
int main() {
    // p points to NULL
    int *p = NULL;
    // returns 0
    return 0;
}
