Vk.heap_bytes pulled the Vk module - and on lang/uifree the GL window path - into a plain program, which then failed to link (_cgl_offscreen, lgl_GetError). Os.heap_bytes is malloc_zone_statistics through a weak reference (0 where there is none, and on Windows). Reseeded. Docs for it and for Json.free / Json.free_all.

Gives back every node and list of a tree <a href="json-parse"><code>Json.parse</code></a> made, once what it describes has been built. Ludic has no garbage collector, so a tree read and dropped is otherwise kept for as long as the program runs. The tree's strings stay, because a reader may keep a name it took out of it; when nothing was kept, <a href="json-free_all"><code>Json.free_all</code></a> gives those back too. Only for a parsed tree: one put together by hand may share a node or hold a literal.

```ludic

|
program Free {
|
|
entry {
|
|
let doc = Json.parse("{\"hp\": 3}")
|
|
let hp = value_as_int(value_get(doc, "hp"))
|
|
Json.free(doc)
|
|
print(hp)
|
|
}
|
|
}

```
