+# Dir
+----------
+
+This header provides a simple directory walker, here is an example usage:
+
+```c
+typedef struct source_t {
+    str_t filename;
+    struct source_t *next;
+} source_t;
+
+sources_t get_sources(arena_t *arena, strview_t path) {
+    uint8 tmpbuf[KB(5)] = {0};
+    arena_t scratch = arenaMake(ARENA_STATIC, sizeof(tmpbuf), tmpbuf);
+
+    dir_t *dir = dirOpen(&scratch, path);
+    dir_entry_t *entry = NULL;
+
+    source_t *sources = NULL;
+
+    while ((entry = dirNext(&scratch, dir))) {
+        if (entry->type != DIRTYPE_FILE) {
+            continue;
+        }
+
+        strview_t ext = fileGetExtension(strv(entry->name));
+        if (!strvEquals(ext, strv(".c"))) {
+            continue;
+        }
+
+        source_t *new_source = alloc(arena, source_t);
+        new_source->filename = strFmt(arena, "%v/%v", path, entry->name);
+        new_source->next = sources;
+        sources = new_source;
+    }
+
+    return sources;
+}
+
+int main() {
+    arena_t arena = arenaMake(ARENA_VIRTUAL, GB(1));
+    source_t *sources = get_sources(&arena, strv("src/colla"));
+    while (sources) {
+        info("> %v", sources->filename);
+        sources = sources->next;
+    }
+    arenaCleanup(&arena);
+}
