✨ scan_jsonescape(3) — parse JSON escaped string ✨

okay bestie, buckle up 💖 this one lives in the Library Functions Manual, section 3, and it's literally here to un-escape JSON strings for you. no cap.

---

🌸 NAME 🌸

scan_jsonescape — parse JSON escaped string 🦋

---

🎀 SYNTAX 🎀

#include <libowfat/textcode.h>

size_t scan_jsonescape(const char *src,char *dest,size_t* destlen);

---

💅 DESCRIPTION 💅

so scan_jsonescape reads JSON-escaped text out of src and drops it into dest, leaving you with a whole UTF-8 string in there. it's giving translator energy 🌈.

parsing stops at any of these three things, periodt:

• the 0 terminator
• invalid input characters
• a double quote that was not escaped

once it's done, it writes the number of bytes sitting in dest into *destlen, and it returns the number of bytes it decoded from src. two numbers, one call, iconic 👑

the lowkey chaotic part (in a good way):

• dest can be NULL 🙈
• destlen can be NULL 🙈
• dest can be src (yes, in-place, she contains multitudes)

to make sure dest is big enough, you've got two options, bestie: either allocate strlen(src)+1 bytes, or call scan_jsonescape twice — the first time with dest == NULL, and *destlen will still be written. that's the trick, iykyk 🧚

---

⭐ RETURN VALUE ⭐

scan_jsonescape returns the number of bytes successfully parsed from src. that's it, that's the number 💜

---

🍓 EXAMPLES 🍓

scan_jsonescape("test\n\");",buf,&i) -> return 6, i=5, buf="test\n".

look at her go ✨ return 6, i=5, and buf="test\n". ate, no crumbs.
