Draft

Ruby is used mainly for Testing and Tools in Mer and thus it is going to Mer:Tools project in community OBS. As ruby consists of numerous different gems, a packages that contain ruby libraries or applications, there is need for consistent policy how we should package them.

[edit] Package Naming

ruby gems packages should hae follow prefix in package names: rubygem-

[edit] Packaging with gem2rpm

First start by installing Mer SDK. After that is done login to the SDK and install rubygem-gem2rpm 

sudo zypper install rubygem-gem2rpm

After that is done you need to fetch the gem you want to package. 

gem fetch <mygemname>

When the gem is downloaded you can create .spec file with following cmd 

gem2rpm-opensuse <mygemname-version>.gem > rubygem-<mygemname>.spec

After the .spec file is created next thing is to check if there are any hacks needed that needs to be preserved.

When the possible modifications are done it is time to add files, add new entry to .changes file and upload the new packaging.

[edit] Packaging with bundler

Some ruby applications have a significant number of gems. Rather than package them individually you can use bundler and create a single package that installs all the gems to a dedicated location.

To develop and prepare this package you need a suitable SDK with bundler 1.2 installed

Copy the Gemfile and .lock to a development directory (later this will be called DEVSRC) and run 

 bundle install --path=vendor/bundle

You may have local git repos checked out from github etc so to use those see the comments in the Gemfile. You need something like: 

  bundle config local.ruote-amqp /maemo/devel/BOSS/src/ruby-ruote-amqp

for each local git repo you're working with

In the DEVSRC ensure all commits are up-to-date and freeze using: 

 bundle pack --all

Then cd to the osc project and create a spec-file like this: 

Name:           sdk-webapp-bundle
Summary:        Bundle of gems used by sdk-webapp
Version:        0.0.1
Release:        1
#

#

# This is the BR for all enclosed gems

#

# DEVSRC=/mer/mer/devel/mer-sdk/sdk-webapp-bundle ./update-pkg.sh

Source0: Gemfile

Source2: sdk-webapp-bundle.rpmlintrc
Source3: haml-3.1.7.gem

cp %{SOURCE0} .
cp %{SOURCE1} .
cp %{SOURCE2} .

mkdir -p vendor/cache;
for file in %{lua: for i, p in ipairs(sources) do print(p.." ") end}; do if [[ ${file: -3:3} == "gem" ]]; then cp $file vendor/cache; elif [[ ${file: -3:3} == "bz2" ]]; then tar xf $file; fi; done

%build
%install
mkdir -p %{buildroot}/%{_libdir}/%{name}
bundle install --local --standalone --deployment --binstubs=%{buildroot}/%{_bindir}/ --no-cache --shebang=%{_bindir}/ruby
find . -name .gitignore -print0 | xargs --no-run-if-empty -0 rm

# Install everything we just built
cp -al . %{buildroot}/usr/lib/%{name}/

# Don't install the rpmlintrc
rm %{buildroot}/usr/lib/%{name}/$(basename %{SOURCE2})

# Change #!/usr/local/bin/ruby to #!/usr/bin/ruby
fgrep -rl "usr/local/bin" %{buildroot} | xargs --no-run-if-empty sed -i -e 's_/usr/local/bin_/%{_bindir}_'g
# Change ../../../../../BUILD to {%_libdir}/%{name}
fgrep -rl "../../../../../BUILD" %{buildroot} | xargs --no-run-if-empty sed -i -e 's_../../../../../BUILD_%{_libdir}/%{name}_'g
# Remove references to buildroot
fgrep -rl "%{buildroot}" %{buildroot} | xargs --no-run-if-empty sed -i -e 's_%{buildroot}__'g

%files
%defattr(-,root,root,-)
%{_libdir}/%{name}/
%{_bindir}


Set DEVSRC to the dir where development takes place.

This script updates the .spec with any gems and tarballs (it should be added to the rubygem-bundle but include it in the packaging for now) 

#!/bin/bash

rm -f *gem *tar.bz2
cp $DEVSRC/Gemfile .
cp $DEVSRC/Gemfile.lock .
cp $DEVSRC/vendor/cache/*gem .
> Source.new

c=3
for src in $(cd $DEVSRC; find vendor/cache/  -mindepth 1 -maxdepth 1 -type d); do
   tar cfj $(basename $src).tar.bz2 -C $DEVSRC $src;
   echo Source$((c++)): $(basename $src).tar.bz2 >> Source.new
done
for g in *gem; do echo Source$((c++)): $(basename $g) >> Source.new ; done; 

sed -i '/^Source2:/,/# SourceEnd/ {//!d}; /^Source2:/r Source.new' *.spec
rm Source.new

There's a lua macro to recreate the bundle cache ready for building.

Update the changelog and version and run 

osc ar

Then osc ci
