I would like to parse a txt data, and there is "@data" keyword in it.
What i wanna do is take the number after the keyword ,and change it into a hex
number.
I cannot get the data after the "@data" keyword so far...
:(
[code]
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
//#include <libgen.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <unistd.h>
#include <glib.h>
/////////////////////////////////////////////////////////////
char DATA[50]="";

void
parse_file (const char *filename) {
GScanner *scanner;
GTokenType ttype;
GScannerConfig config = {

};
/* first open the file; bail if not successful */
int fd = open (filename, O_RDONLY);
if (fd < 0) {
printf ("Failed to open file \"%s\". Skipping ...\n", filename);
return;
}
printf ("Parsing file \"%s\":\n", filename);
scanner = g_scanner_new (&config);
g_scanner_input_file (scanner, fd);
ttype=g_scanner_get_next_token (scanner);
while (ttype != G_TOKEN_EOF ) {
if( ttype!=G_TOKEN_IDENTIFIER ) // && ttype!=G_TOKEN_INT )
{
ttype=g_scanner_get_next_token(scanner);
continue;
}
else
{

}

{

printf("@data is=0x%x\n",scanner->value.v_int);
sprintf(DATA,"0x%x",scanner->value.v_int);
printf("\n\n\ndata=0x%x\n",DATA);
}
ttype=g_scanner_get_next_token(scanner);
}
/* clean up */
g_scanner_destroy (scanner);
close (fd);
}
/**

* lexical scanner.
*/
int
main (int argc, char **argv) {
for (int i = 1; i < argc; ++ i) {
parse_file (argv[i]);
}
return (EXIT_SUCCESS);
}
[/code]
parsed txt file contains:
[code]
/*---------------------------------------------------------------------
* @fn function1
*
* @brief this is function1
* @data 0x1
*----------------------------------------------------------------------*/
/*---------------------------------------------------------------------
* @fn function2
*
* @brief this is function2
* @data 2
*----------------------------------------------------------------------*/
/*---------------------------------------------------------------------
* @fn function3
*
* @brief this is function3
* @data 0x123
*----------------------------------------------------------------------*/
/*---------------------------------------------------------------------
* @fn function4
*
* @brief this is function4
* @data 123
*----------------------------------------------------------------------*/
[/code]
Could someone give me a hand?
many thanks~
