HOW TO: CREATE THE [email protected] FORMULA

Three repos:

  1. ~/repos/binary-releases (https://github.com/JuulLabs-OSS/binary-releases)
  2. ~/repos/homebrew-mynewt (https://github.com/JuulLabs-OSS/homebrew-mynewt)
  3. ~/go/src/mynewt.apache.org/newt (https://github.com/apache/mynewt-newt)

Create the binary bottle

Create the newt binary

Note: We have to do this by hand rather than with brew install --build-bottle. This is necessary for the resulting binary to contain the correct git hash in its newt version output.

cd ~/go/src/mynewt.apache.org/newt
git fetch origin --tags
git checkout mynewt_1_7_0_tag
./build.sh
sudo cp newt/newt /usr/local/Cellar/mynewt-newt

Make sure the resulting build is clean

/usr/local/Cellar/mynewt-newt/newt version

(ensure a git hash is displayed without the word "dirty").

Create to working directory and cd to it

Any directory will do. The remainder of these steps are run from this directory.

mkdir /tmp/newt17
cd /tmp/newt17

Create the bottle.

brew bottle mynewt-newt

Push binary.

I don't know why, but the bottle filename contains an extra dash. Remove it with the cp command below.

mkdir -p ~/repos/binary-releases/mynewt-newt-tools_1.7.0
cp mynewt-newt--1.7.0.high_sierra.bottle.tar.gz ~/repos/binary-releases/mynewt-newt-tools_1.7.0/mynewt-newt-1.7.0.high_sierra.bottle.tar.gz

Create a PR from ~/repos/binary-releases/mynewt-newt-tools_1.7.0.

Create the formulae

Setup

wget https://github.com/apache/mynewt-newt/archive/mynewt_1_7_0_tag.tar.gz
shasum -a 256 mynewt_1_7_0_tag.tar.gz   # Remember the output of this command.

Edit /usr/local/Homebrew/Library/Taps/juullabs-oss/homebrew-mynewt/mynewt-newt.rb.

  1. Replace 1.6 with 1.7
  2. Replace 1_6 with 1_7
  3. In the bottle do block, replace the sha256 with that in the output from the brew bottle command.
  4. Replace the top level "sha256" field with the shasum output (previous shell command).

Create version formula.

cp /usr/local/Homebrew/Library/Taps/juullabs-oss/homebrew-mynewt/[email protected] /usr/local/Homebrew/Library/Taps/juullabs-oss/homebrew-mynewt/[email protected]
