term::send - General output to terminals


package require Tcl 8.4

package require term::send ?0.1?

::term::send::wrch chan str

::term::send::wr str


This package provides the most primitive commands for sending characters to a terminal. They are in essence convenient wrappers around the builtin command puts.

::term::send::wrch chan str
Send the text str to the channel specified by the handle chan. In contrast to the builtin command puts this command does not terminate the string with a line terminator. It also forces an flush of Tcl internal and OS buffers to ensure that the characters are processed immediately.
::term::send::wr str
This convenience command is like ::term::send::wrch, except that the destination channel is fixed to stdout.


This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category term of the Tcllib Trackers []. 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.

Note further that attachments are strongly preferred over inlined patches. Attachments can be made by going to the Edit form of the ticket immediately after its creation, and then using the left-most button in the secondary navigation bar.
