All preprocessor commands begins with the hash (pound) symbol #. A C macro is just a preprocessor command that is defined using the #define preprocessor directive. During the preprocessing stage, the C preprocessor (a part of the C compiler) simply substitutes the body of the macro wherever its nam...

On Mac and Linux, the meteor command line tool assumes that the ssh command line tool, used to make secure connections to other computers, is always present. On Windows, this tool needs to be installed. Below are listed two options for setting it up and using it.

X-macros are a preprocessor-based technique for minimizing repetitious code and maintaining data / code correspondences. Multiple distinct macro expansions based on a common set of data are supported by representing the whole group of expansions via a single master macro, with that macro's replacem...

Emacs is a text editor whose most prominent feature is the ability of users to programmatically customize nearly all aspects of it. This is facilitated though a special dialect of the Lisp programming language, called Emacs Lisp, created specifically for use in the Emacs editor. There are a mult...

A walkthrough of macros can be found in The Rust Programming Language (a.k.a. The Book).

Machine Learning is the science (and art) of programming computers so they can learn from data. A more formal definition: It is the field of study that gives computers the ability to learn without being explicitly programmed. Arthur Samuel, 1959 A more engineering-oriented definition: A compu...

The Purpose of Macros Macros are intended for generating code, transforming code and providing new notations. These new notations can be more suited to better express the program, for example by providing domain-level constructs or entire new embedded languages. Macros can make source code mor...

Remote management of multiple docker engine hosts. docker-machine manages remote hosts running Docker. The docker-machine command line tool manages the full machine's life cycle using provider specific drivers. It can be used to select an "active" machine. Once selected, an active m...

The main difference between macros and functions is, that macros are evaluated within the current context, while functions open a new scope within the current one. Thus, variables defined within functions are not known after the function has been evaluated. On the contrary, variables within macros...

The ' symbol used in the macroexpand example is just syntactic sugar for the quote operator. You could have written (macroexpand (quote (infix 1 + 2))) instead. Macros are just functions that run at compile time, i.e. during the eval step in a read-eval-print-loop. Reader macros are anothe...

Macros are a form of compile time metaprogramming. Certain elements of Scala code, such as annotations and methods, can be made to transform other code when they are compiled. Macros are ordinary Scala code that operate on data types that represent other code. The [Macro Paradise][] plugin extends t...

Emacs is described as a self-documenting editor, and provides lots of information on how to use it within the editor itself. Amongst the entry points to this documentation is a tutorial, information about what functions is available related to a given topic,a information about the bindings between...

The topic uses PHP-ML for all machine learning algorithms. The installation of the library can be done using composer require php-ai/php-ml The github repository for the same can be found here. Also it is worth noting that the examples given are very small data-set only for the purpose of dem...

macro"string" # short, string macro form @macro_str "string" # long, regular macro form macro`command` String macros are not quite as powerful as plain old strings — because interpolation must be implemented in the macro's logic, string macros are unable to contain str...
