Workflow - release to git

Single-line Method

Giving Rock a run for its money is now quicker and easier than ever. Run the following command in your shell, and life is good. Tested and working on OS X and Ubuntu. Should work on any POSIX compliant system.

bash -c "`curl -L http://github.com/nddrylliog/rock/raw/master/utils/ooc-install.sh`"

So you've tried rock..

So you've tried rock, the sky is shining, the sun is singing, and the birds are blue. Wonderful.

But then you stumbled upon a bug that's already fixed in the git, or you just heard about some new awesome feature that will be in the next release.

But, you don't wanna wait. Then again - who could blame you for this?

Quick way

  1. Extract release, cd, make
  2. git clone git://github.com/nddrylliog/rock.git && cd rock
  3. ROCK_DIST=. OOC=../rock-x.y.z*/bin/rock make self

And you're done! Of course, rock-x.y.z should be the number of the release you're working from.

Don't forget to check that you're really using the latest rock you compiled, with 'rock -V', which should display 'head', and the build date and time. Have fun!

Long way with detailed explanations

Rock is a self-hosting compiler, each release of rock is used to build the next release of rock. To use the git version, simply follow these steps (specific steps may vary depending on your OS):

  1. Check that you have a stable release of rock (0.9.1 as of 8/05/2010), you can download the release from here.

  2. Let's assume that you unpackaged the folder to /usr/share/rock-0.9.1. "cd /usr/share/" and clone the latest development copy "git clone git://github.com/nddrylliog/rock.git"

  3. "cd rock/", inside this directory execute "OOC=../rock-0.9.1/bin/rock ROCK_DIST=. make self". This will build the latest binary for rock using the stable release. This is self-hosting in action :)

  4. Finally do "/path/to/rock -version" this should display "rock head, built on 2010-05-08 at 23:45". If it reports head as the version you are now using the latest release of rock. Enjoy living on the edge :)

Makefile, thou art a heartless witch

Let's walk through the different targets the Makefile offers us

  • 'make' == 'make bootstrap'. That's what you did if you installed from a source release. It compiles rock from a pre-generated set of C sources located in the build/ folder, then rebuilds it with itself by calling 'make self'

  • 'make self'. Recompile rock with itself. That overwrites the current rock executable with the new one (hence, will fail on OSX/Win32, which refuse to overwrite a running executable). For this reason, and also because if you recompile a messed up version, you'll have no safety net, I recommend to do something like 'cp bin/rock bin/safe_rock && ROCK_DIST=. OOC=bin/safe_rock make self'

  • 'make noclean' Used by devs who want to recompile rock with itself without removing the rock_tmp/ directory, hence allowing partial recompilation. Use with care, or don't use at all, because in some specific cases it introduces bugs (due to the fragile base class problem)

  • 'make prepare_bootstrap' Used to generate the set of C sources in the build/ directory. Used to make a release of rock so you mere mortals (hem, users) can bootstrap cleanly.

  • 'make grammar' Regenerate NagaQueen.c from ../nagaqueen/grammar/nagaqueen.leg with greg. Both nagaqueen and greg are nddrylliog's projects on github.com
