bpo-14019 has a patch, unrelated to the issue, that adds test.test_formatter. There still is no such file, so I open this issue to move the patch here. It is the second version, responding to review by Ezio Melotti.

But formatter has been deprecated since 3.4. It was originally scheduled to be removed in 3.6, but we decided to delay such removals until after 2.7 EOL. That is now past. Do we add tests for a deprecated module? If so, the patch, aDo we still want to remove formatter? If so, when?

[terryjreedy]

The patch is by Francisco Freire (francisco.freire) * (CLA signed). There is apparently no way to directly move a patch from one issue to another, so I download and upload.

IMHO, 3.10 is a good time to remove formatter

[tiran]

The formatter has been deprecated for a long time. It's been issuing a DeprecationWarning on import since 3.5. Let's remove it.

@christian.heimes

Thank you Christian

I also discuss this issue on python-dev and everybody agree with removing this module.

I will remove this module ;)

I took a look at the module and its doc. It is based on a 1980s model of document processing that has been somewhat superseded by html, xml, and pdf. The module itself has been pretty well superseded by stdlib and external moudles. IDLE, for instance, displays idle.html in a tkinter Text widget about 160 lines by subclassing htmlparser.

One obsolescent 'feature' is that fonts are defined by (size, italic, bold, teletype), where 'teletype' is a bool of undefined meaning. There is no way I saw to designate a font family like 'Source Code Pro' or 'Monaco'.

Since the module is unmaintained and frozen, anyone importing it can incorporate whatever class code they need.
