If you want to contribute new docs or report problems, I invite you to do so on the project issue tracker. The goal of fpm is to make it easy and quick to build packages such as rpms, debs, OSX packages, etc. fpm, as a project, exists with the following principles in mind: • If fpm is not helping you make packages easily, then there is a bug in fpm. • If you are having a bad time with fpm, then there is a bug in fpm. • If the documentation is confusing, then this is a bug in fpm. If there is a bug in fpm, then we can work together to fix it. If you wish to report a bug/problem/whatever, I welcome you to do on the project issue tracker. You can find out how to use fpm in the documentation. Contents 1 fpm Documentation, Release 1.7.0 2 Contents CHAPTER 1 Backstory Sometimes packaging is done wrong (because you can’t do it right for all situations), but small tweaks can fix it.

ROOT Package Management: “Lazy Install” Approach
ROOT package management: “lazy install” approach Oksana Shadura ROOT Monday meeting Outline ● How we can improve artifact management (“lazy-install”) system for ROOT ● How to organise dependency management for ROOT ● Improvements to ROOT CMake build system ● Use cases for installing artifacts in the same ROOT session Goals ● Familiarize ROOT team with our planned work ● Explain key misunderstandings ● Give a technical overview of root-get ● Explain how root-get and cmake can work in synergy Non Goals We are not planning to replace CMake No change to the default build system of ROOT No duplication of functionality We are planning to “fill empty holes” for CMake General overview Manifest - why we need it? ● Easy to write ● Easy to parse, while CMakeLists.txt is impossible to parse ● Collect information from ROOT’s dependencies + from “builtin dependencies” + OS dependencies + external packages to be plugged in ROOT (to be resolved after using DAG) ● It can be easily exported back as a CMakeLists.txt ● It can have extra data elements [not only what is in CMakeLists.txt, but store extra info] ○ Dependencies description (github links, semantic versioning) ■ url: "ssh://[email protected]/Greeter.git", ■ versions: Version(1,0,0)..<Version(2,0,0) Manifest is a “dump” of status of build system (BS), where root-get is just a helper for BS Manifest - Sample Usage scenarios and benefits of manifest files: LLVM/Clang LLVM use CMake as a LLVMBuild utility that organize LLVM in a hierarchy of manifest files of components to be used by build system llvm-build, that is responsible for loading, verifying, and manipulating the project's component data.

Setting up Your Environment
APPENDIX A Setting Up Your Environment Choosing the correct tools to work with asyncio is a non-trivial choice, since it can significantly impact the availability and performance of asyncio. In this appendix, we discuss the interpreter and the packaging options that influence your asyncio experience. The Interpreter Depending on the API version of the interpreter, the syntax of declaring coroutines change and the suggestions considering API usage change. (Passing the loop parameter is considered deprecated for APIs newer than 3.6, instantiating your own loop should happen only in rare circumstances in Python 3.7, etc.) Availability Python interpreters adhere to the standard in varying degrees. This is because they are implementations/manifestations of the Python language specification, which is managed by the PSF. At the time of this writing, three relevant interpreters support at least parts of asyncio out of the box: CPython, MicroPython, and PyPy. © Mohamed Mustapha Tahrioui 2019 293 M. M. Tahrioui, asyncio Recipes, https://doi.org/10.1007/978-1-4842-4401-2 APPENDIX A SeTTinG Up YouR EnViROnMenT Since we are ideally interested in a complete or semi-complete implementation of asyncio, our choice is limited to CPython and PyPy. Both of these products have a great community. Since we are ideally using a lot powerful stdlib features, it is inevitable to pose the question of implementation completeness of a given interpreter with respect to the Python specification. The CPython interpreter is the reference implementation of the language specification and hence it adheres to the largest set of features in the language specification. At the point of this writing, CPython was targeting API version 3.7.
