# coroutine::auto(3tcl) 1.1.3 coroutine "Coroutine utilities"

## Name

coroutine::auto - Automatic event and IO coroutine awareness

## Synopsis

- package require Tcl 8.6
- package require coroutine::auto 1.1.3
- package require coroutine 1.1

## Description

The coroutine::auto package provides no commands or other directly visible functionality. Built on top of the package coroutine, it intercepts various builtin commands of the Tcl core to make any code using them coroutine-oblivious, i.e. able to run inside and outside of a coroutine without changes.

The commands so affected by this package are

after
exit
gets
global
read
update
vwait

## Bugs, Ideas, Feedback

When proposing code changes, please provide unified diffs, i.e the output of diff -u.
