Interfacing Gaudi with Python Objectives
8 Interfacing Gaudi with Python Gaudi Framework Tutorial, 2004 Objectives After completing this lesson, you should be able to: • Understand how Gaudi is interfaced to Python • Convince you that Python is a very good programming language for Rapid Prototyping • Write simple Python scripts to access LHCb data 8-2 Gaudi Framework Tutorial, 2004 Python Language Python is an Open Source programming language created by Guido van Rossum. While it has been available since 1990, it has recently seen a dramatic increase in popularity in a wide variety of domains Python is simple, elegant, powerful and reliable Features: • Variables & Arithmetic expressions • String manipulations • Conditionals (if/else statements), Loops (for/while) • Functions, Lists, Dictionaries, Classes (Objects), Exceptions , Modules 8-3 Gaudi Framework Tutorial, 2004 Why Python? Free, Open-Source, Maintainable Cross-Platform, Portable General-Purpose, High-level, Object-Oriented Interpreted • However it is quite fast (byte code idea from Java) Dynamically typed, Introspective • Not need to declare any variable Simple syntax, Robust • Emphasis by the author to minimize typing Variety of Shells Powerful built-in types and modules Î Ideal for Scripting and Prototyping 8-4 Gaudi Framework Tutorial, 2004 Python as a “Glue” Extension Modules • Very easy to interface to C++ classes (C-API) Collaborative • Extension modules can be plugged and used together Very rich set LHC modules specialized generic modules Several GUI toolkits EDG API PVSS XML Database GUIGUI Python shell JPE PyROOT gaudipython mathmath Gateways to other frameworks Java Root Gaudi Very rich set Classes Classes Framework of Python standard 8-5 Gaudi Framework Tutorial, 2004 modules Python Binding Techniques Python provides a very complete C-API • By hand bindings are possible but even for medium-sized projects, it becomes cumbersome and unmaintainable. -

Using the Go Programming Language in Practice
MASTER’S THESIS | LUND UNIVERSITY 2014 Using the Go Programming Language in Practice Fredrik Pettersson, Erik Westrup Department of Computer Science Faculty of Engineering LTH ISSN 1650-2884 LU-CS-EX 2014-19 Using the Go Programming Language in Practice Erik Westrup Fredrik Pettersson <[email protected]> <[email protected]> <[email protected]> <[email protected]> June 5, 2014 Master’s thesis work carried out at Axis Communications AB for the Department of Computer Science, Lund University. Supervisors: Jonas Skeppstedt <[email protected]> Mathias Bruce <[email protected]> Robert Rosengren <[email protected]> Examiner Jonas Skeppstedt Abstract When developing software today, we still use old tools and ideas. Maybe it is time to start from scratch and try tools and languages that are more in line with how we actually want to develop software. The Go Programming Language was created at Google by a rather famous trio: Rob Pike, Ken Thompson and Robert Griesemer. Before introducing Go, the company suffered from their development process not scaling well due to slow builds, uncontrolled dependencies, hard to read code, poor documenta- tion and so on. Go is set out to provide a solution for these issues. The purpose of this master’s thesis was to review the current state of the language. This is not only a study of the language itself but an investigation of the whole software development process using Go. The study was carried out from an embedded development perspective which includes an investigation of compilers and cross-compilation. We found that Go is exciting, fun to use and fulfills what is promised in many cases. -
Application Programming Interface (API) Is a Specification Intended to Be Used As an Interface by Software Components to Communicate with Each Other
Application programming interface 1 Application programming interface An application programming interface (API) is a specification intended to be used as an interface by software components to communicate with each other. An API may include specifications for routines, data structures, object classes, and variables. An API specification can take many forms, including an International Standard such as POSIX or vendor documentation such as the Microsoft Windows API, or the libraries of a programming language, e.g. Standard Template Library in C++ or Java API. An API differs from an application binary interface (ABI) in that the former is source code based while the latter is a binary interface. For instance POSIX is an API, while the Linux Standard Base is an ABI.[1] Language used An API can be: • language-dependent, meaning it is only available by using the syntax and elements of a particular language, which makes the API more convenient to use. • language-independent, written so that it can be called from several programming languages. This is a desirable feature for a service-oriented API that is not bound to a specific process or system and may be provided as remote procedure calls or web services. For example, a website that allows users to review local restaurants is able to layer their reviews over maps taken from Google Maps, because Google Maps has an API that facilitates this functionality. Google Maps' API controls what information a third-party site can use and how they can use it. The term API may be used to refer to a complete interface, a single function, or even a set of APIs provided by an organization.
