codemod-tox 0.5.4

Utilities for editing tox.ini

codemod-tox

Handles parsing and modifying some basic tox.ini configuration strings.

# ToxEnvlist.parse("py{37,38}, style")
envlist = py{37,38}, style

# ToxEnv.parse("foo")
[toxenv:foo]

# ToxConditional.parse("-rrequirements.txt\nflask: flask>0")
deps = -rrequirements.txt
       flask: flask>0

You can then do basic modifications on them, or expand by iterating.

>>> str(ToxEnv.parse("py37") | "py38")
"py3{7,8}"
>>> (ToxEnv.parse("py37") | "py38").startswith("py")
True
>>> list(ToxEnv.parse("py37") | "py38")
["py37", "py38"]
>>> str(ToxEnvlist.parse("py37, style").transform_matching(
...     (lambda x: x.startswith("py3")),
...     (lambda y: y | "py38"),
... ))
"py3{7,8}, style"
