Teapot is a decentralised build tool for managing complex cross-platform projects. It has many goals but it is primarily designed to improve the experience for developers trying to make cross-platform applications and libraries with a minimum of overhead.
- Provide useful feedback when dependencies are not met or errors are encountered.
- Decentralised dependency management allows use within private organisations without exposing code.
- Generators can simplify the construction of new projects as well as assist with the development of existing ones.
- The build subsystem provides a simple set of canonical operations for building libraries and executables to minimise configuration overhead.
Ensure that you already have a working install of Ruby 2.0.0+ and run the following to install teapot:
$ gem install teapot
Teapot doesn't have a default centralised package management system but there is a canonical one for developing cross-platform C++ applications. This example shows how to use this framework.
Firstly, create your project by running:
$ teapot create "My Project" https://github.com/kurocha generate-project
$ cd my-project
You will be asked to merge the project file. At present, merge tools are not very good and thus you may need to take a moment to review the changes. You want to keep most of the original file, but you would like to add the define_target blocks which are being added.
In the resulting project directory that has been created, you can see the list of dependencies:
$ teapot list
... lots of output ...
To only see things exported by your current project, you can run:
$ teapot list root
Package root (from /private/tmp/my-project):

Testing is a good idea, and teapot supports test driven development.
$ teapot Test/MyProject
To run all tests:
$ teapot "Test/*"
Provided you are using an environment that supports sanitizers, you can test more thoroughly using:
$ teapot "Test/*" variant-sanitize
We can now build and run the project executable:
$ teapot Run/MyProject
I'm a little teapot,
Short and stout,
Here is my handle (one hand on hip),
Here is my spout (other arm out with elbow and wrist bent).
When I get all steamed up,
Hear me shout,
Tip me over and pour me out! (lean over toward spout)

The resulting executables and libraries will be framework dependent, but are typically located in:
$ cd teapot/platforms/development/$PLATFORM-debug/bin
$ ./$PROJECT_NAME
You can clone another project which will fetch all dependencies:
$ teapot clone https://github.com/kurocha/tagged-format
$ cd tagged-format
$ teapot build Executable/TaggedFormat
- Should packages be built into a shared prefix or should they be built into unique prefixes and joined together either via install or
-Land-I?- Relative include paths might fail to work correctly if headers are not installed into same directory.
- Should packages have some way to expose system requirements, e.g. installed compiler, libraries, etc. Perhaps some kind of
Package#valid?which allows custom logic?
- Fork it
- Create your feature branch (
git checkout -b my-new-feature) - Commit your changes (
git commit -am 'Add some feature') - Push to the branch (
git push origin my-new-feature) - Create new Pull Request
