# coro\_auto(3tcl)

Automatic event and IO coroutine awareness

```

```

## NAME

coroutine::auto - Automatic event and IO coroutine awareness

## SYNOPSIS

package require **Tcl 8.6 9**

package require **coroutine::auto 1.3**

package require **coroutine 1.4**

```

```

## 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**

  - **puts**

  - **read**

  - **socket**

  - **update**

  - **vwait**

Please report such in the category *coroutine* of the *Tcllib Trackers* \[http://core.tcl.tk/tcllib/reportlist\]. Please also report any ideas for enhancements you may have for either package and/or documentation.

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