Automating Your Sync Testing
APPLICATION NOTE By automating system verification and conformance testing to ITU-T synchronization standards, you’ll save on time and resources, and avoid potential test execution errors. This application note describes how you can use the Paragon-X’s Script Recorder to easily record Tcl, PERL and Python commands that can be integrated into your own test scripts for fast and efficient automated testing. AUTOMATING YOUR SYNC TESTING calnexsol.com Easily automate synchronization testing using the Paragon-X Fast and easy automation by Supports the key test languages Pre-prepared G.8262 Conformance recording GUI key presses Tcl, PERL and Python Scripts reduces test execution errors <Tcl> <PERL> <python> If you perform System Verification language you want to record i.e. Tcl, PERL SyncE CONFORMANCE TEST and Conformance Testing to ITU-T or Python, then select Start. synchronization standards on a regular Calnex provides Conformance Test Scripts basis, you’ll know that manual operation to ITU-T G.8262 for SyncE conformance of these tests can be time consuming, testing using the Paragon-X.

PHP: Constructs and Variables Introduction This Document Describes: 1
PHP: Constructs and Variables Introduction This document describes: 1. the syntax and types of variables, 2. PHP control structures (i.e., conditionals and loops), 3. mixed-mode processing, 4. how to use one script from within another, 5. how to define and use functions, 6. global variables in PHP, 7. special cases for variable types, 8. variable variables, 9. global variables unique to PHP, 10. constants in PHP, 11. arrays (indexed and associative), Brief overview of variables The syntax for PHP variables is similar to C and most other programming languages. There are three primary differences: 1. Variable names must be preceded by a dollar sign ($). 2. Variables do not need to be declared before being used. 3. Variables are dynamically typed, so you do not need to specify the type (e.g., int, float, etc.). Here are the fundamental variable types, which will be covered in more detail later in this document: • Numeric 31 o integer. Integers (±2 ); values outside this range are converted to floating-point. o float. Floating-point numbers. o boolean. true or false; PHP internally resolves these to 1 (one) and 0 (zero) respectively. Also as in C, 0 (zero) is false and anything else is true. • string. String of characters. • array. An array of values, possibly other arrays. Arrays can be indexed or associative (i.e., a hash map). • object. Similar to a class in C++ or Java. (NOTE: Object-oriented PHP programming will not be covered in this course.) • resource. A handle to something that is not PHP data (e.g., image data, database query result). -
BSDLUA Slides (Application/Pdf
BSDLUA (in three parts) Evolved Unix Scripting Ivan Voras <[email protected]> What is BSDLUA? ● An experimental idea ● Use Lua for projects, tools, etc. which do not require C and would be more easily implemented in a scripting language ● An “in between” language – low-level features of C with integration capabilities of shell scripts Why??? ● The $1M question: what in the world would make someone program in something which is not /bin/sh ??? ● /bin/sh is the best thing since the invention of the bicycle... from the time when Unix programmers had real beards... (More specifically) ● I personally miss a “higher level” scripting language in the base system ● In the beginning there was TCL (or so I heard... it was before my time) ● The there was Perl... ● Both were thrown out – For good reasons What is wrong with shell scripts? ● Nothing … and everything ● Good sides: integration with system tools via executing programs, sourcing other scripts ● Bad sides: … somewhat depend on personal tastes … for me it's the syntax and lack of modern features ● Talking about the /bin/sh POSIX shell – more modern shells have nicer languages Why not use /bin/sh? ● (for complex programs) ● Syntax from the 1970-ies ● No local variables ● No “proper” functions (with declared arguments) ● Need to escape strings more often than what would sanely be expected ● Relies on external tools for common operations (tr, grep, join, jot, awk...) ● Too much “magic” in operation Why use Lua? (1) ● As a language: ● Nicer, modern language with lexical scoping ● Namespaces -
