File name and extension parsing functionality are removed because it's difficult to distinguish between a hidden dir (ex: .git) and filename. Their code are not completely removed only commented. So if still you want use that functionality uncomment and use it.
If you want to use this on your project just place path.c and path.h then compile it along with your project. But if you want test it before using it on your project clone this repo and their is a Makefile from where you can compile the source and test file together.
- clone this repo
git clone https://github.com/PrajwalCH/path_module cd path_module - Compile it by running
makeor for debug buildmake DEBUG=1
There are only 2 functions. one for parsing and one for debug printing the path structure.
// path structure
struct Path {
char *dirname;
char *basename;
size_t dirname_len;
size_t basename_len;
};
struct Path path_parse(char *pathname);
void path_dbgln(char *pathname, struct Path *path);There is also a test file in src dir where you can see example.
// main.c
#include "path.h"
int main(void)
{
char *pathname = "/projects/path_module/path.c";
struct Path path = path_parse(pathname);
path_dbgln(pathname, &path);
}Output: 
If you want to print or copy individual parts by yourself..
int main(void)
{
char *pathname = "/projects/path_module/path.c";
struct Path path = path_parse(pathname);
// there is no need to use length while printing for basename but it's recommend to use if want to copy on another buffer for safe.
printf("dirname: %.*s\n", (int)path.dirname_len, path.dirname);
printf("basename: %s\n", path.basename);
// copy to another buffer
char dirname[path.dirname_len + 1];
memset(dirname, 0, sizeof(dirname));
memcpy(dirname, path.dirname, path.dirname_len);
printf("your dirname: %s\n", dirname);
