node:readline
#Import
import readline from "nstdlib/node/readline";Note
The API is available, but not everything works. Works over any pair of streams. The terminal half. Raw mode, the window size, a descriptor to read. Needs a host to back the TTY handle over node_binding_tty_wrap_dispatch, and native/ does, over termios and ioctl(TIOCGWINSZ). No runtime here delivers SIGWINCH, so a 'resize' event never fires.
#Support
- nstd: Gives the same output as Node.js in side-by-side tests: repl.
- Browser: Loads with a minimal
processobject. 8 of Node's 8 exports are available. No behavior check covers it yet.
#Exports (8)
Every name Node.js exports from this module, and what you get when you read it, as a named import or as a property of the default import:
- ✅ A value, both ways. An export that throws an error naming the missing feature also counts.
- ⚠️ A value one way,
undefinedthe other. - ❔
undefinedboth ways. - ❌ Not exported at all.

#Diagnostics
nstdlib running inside Node.js. This isn't an environment it's meant for, so it isn't shown above, but it tells a library problem from an environment one:
coverage: 8/8 of the host's export names answer inside host node. API only. Works over any pair of streams. The terminal half. Raw mode, the window size, a descriptor to read. Needs a host to back theTTYhandle overnode_binding_tty_wrap_dispatch, andnative/does, overtermiosandioctl(TIOCGWINSZ). No runtime here deliversSIGWINCH, so a'resize'event never fires.smoke: Imports in a clean child process.node-suite: 22/22 of Node's own eligible tests pass with ./dist inside host node. A failure there and in the page is the library's, one only in the page is the engine's.
