From 028f11f9e40e4812a57e84fb670bbf2f30a60525 Mon Sep 17 00:00:00 2001 From: Michka Popoff Date: Mon, 10 Feb 2020 07:24:50 +0100 Subject: [PATCH] python@2: delete (#49796) EOL 1 January 2020. We gave it 1 month more to live so that people had time to migrate. All in all, developers had 11 years to do their migration. You can use the `brew extract` command and maintain python@2 in your own tap if necessary: https://docs.brew.sh/How-to-Create-and-Maintain-a-Tap --- Aliases/python2 | 1 - Formula/python@2.rb | 315 -------------------------------------------- 2 files changed, 316 deletions(-) delete mode 120000 Aliases/python2 delete mode 100644 Formula/python@2.rb diff --git a/Aliases/python2 b/Aliases/python2 deleted file mode 120000 index 8db32ddbd2cee..0000000000000 --- a/Aliases/python2 +++ /dev/null @@ -1 +0,0 @@ -../Formula/python@2.rb \ No newline at end of file diff --git a/Formula/python@2.rb b/Formula/python@2.rb deleted file mode 100644 index a100b443f993f..0000000000000 --- a/Formula/python@2.rb +++ /dev/null @@ -1,315 +0,0 @@ -class PythonAT2 < Formula - desc "Interpreted, interactive, object-oriented programming language" - homepage "https://www.python.org/" - url "https://www.python.org/ftp/python/2.7.17/Python-2.7.17.tar.xz" - sha256 "4d43f033cdbd0aa7b7023c81b0e986fd11e653b5248dac9144d508f11812ba41" - revision 1 - head "https://github.com/python/cpython.git", :branch => "2.7" - - bottle do - sha256 "accfaa922708f00afb69ab230199f96e6ecdddd248a1eca586ce1e5e5cfd732b" => :catalina - sha256 "54d3351d6be8268b2f5017894dcc8e083811dfa3812bdb9f79f989873b9a4542" => :mojave - sha256 "cfd5c6eeac37065d19f527bb0798a9caf1928bab3340cd545224861a3c82f219" => :high_sierra - end - - # setuptools remembers the build flags python is built with and uses them to - # build packages later.
