black [OPTIONS] [SRC]...
Options:
+ -c, --code TEXT Format the code passed in as a string.
-l, --line-length INTEGER How many characters per line to allow.
[default: 88]
-t, --target-version [py27|py33|py34|py35|py36|py37|py38]
### NOTE: This is a beta product
-*Black* is already successfully used by several projects, small and big.
+*Black* is already [successfully used](#used-by) by many projects, small and big.
It also sports a decent test suite. However, it is still very new.
Things will probably be wonky for a while. This is made explicit by the
"Beta" trove classifier, as well as by the "b" in the version number.
Having one kind of quotes everywhere reduces reader distraction.
It will also enable a future version of *Black* to merge consecutive
string literals that ended up on the same line (see
-[#26](https://github.com/ambv/black/issues/26) for details).
+[#26](https://github.com/python/black/issues/26) for details).
Why settle on double quotes? They anticipate apostrophes in English
text. They match the docstring standard described in [PEP 257](https://www.python.org/dev/peps/pep-0257/#what-is-a-docstring).
```toml
[tool.black]

+
+```console
+$ black --help

+
+3. In Wing IDE, activate the **OS Commands** panel and define the command **black** to execute black on the currently selected file:
+
+- Use the Tools -> OS Commands menu selection
+- click on **+** in **OS Commands** -> New: Command line..
+ - Title: black
+ - Command Line: black %s
+ - I/O Encoding: Use Default
+ - Key Binding: F1
+ - [x] Raise OS Commands when executed
+ - [x] Auto-save files before execution
+ - [x] Line mode
+
+4. Select a file in the editor and press **F1** , or whatever key binding you selected in step 3, to reformat the file.
