Re: simple text formatting

[Wilko Fokken <wfok@arcor.de>]

Here follows an answer in C:
(best viewed with "tabstop=4" in ~/.vimrc)

you can simply add some more char's (e.g: '/')
to be ignored as whitespace: just add them
to the head of the 'case' list, e.g.   "case '/':"  
without futher additions and recompile: "cc <file.c>

-----------------------------------------------------------
This program is to be called up as a filter, e.g:

	a.out < textfile	> lexical_file
or
	cat textfile | a.out > lexical_file
or
	cat textfile | a.out		# output goes to the screen
-----------------------------------------------------------




#include	<stdio.h>

#define	CR	'\r'				//CarriageReturn
#define	LF	'\n'				//LineFeed
#define	TAB	'\t'				//Tabulator

#define YES	1
#define NO	0

int		ch;						//text
char	newline;				//mark LineFeed condition


main () {
	newline = YES;				//NO Linefeed before text

	while ((ch = getchar()) != EOF) {	//read text
		switch (ch) {
		case CR:
		case TAB:
		case LF:	if (newline == NO) {
						putchar(LF);
						newline = YES;
					}
					break;

		default:	putchar(ch);
					newline = NO;
		}
	}
}
