Downward funargs are local functions that are not returned or otherwise leave their declaration scope. They only can be passed downwards to other functions from the current scope. Two examples. This is a downward funarg: function () { var a = 42; var f = function () { return a + 1; } foo(f); // … Read more
Compiler – compiles code to a lower level code. Example: “Developer code” -> “Machine code” PHP -> C Java -> bytecode Transpiler – compiles code to same level of code/abstraction. Example: “Developer code” -> “Another developer code or version” JavaScript ES2015+ -> JavaScript ES5 Interpreter – interprets code, not really in the same class/league/context with … Read more
The term “pull requests” comes from the distributed nature of how many open source projects organize themselves. Instead of just pushing your changes into the repository (like you would do with a centralized repository, e.g. with Subversion), you are publishing your changes separately and ask the maintainer to pull in your changes. The maintainer then … Read more
Some data types are considered “primitive”, meaning they are not treated like an object and don’t have the properties of an object. On most platforms, integers and characters are examples of types that are primitive but can be boxed. Boxing means wrapping them in an object so they have the behavior of an object. The … Read more
A Fold for Every Occasion We can actually come up with a generic notion of folding which can apply to a whole bunch of different types. That is, we can systematically define a fold function for lists, trees and more. This generic notion of fold corresponds to the catamorphisms @pelotom mentioned in his comment. Recursive … Read more
After grepping through official documentation, it seems that “Vim script” is the “most” official name since nowhere is “VimScript” mentioned in regular sentences. GetLatestVimScripts is often mentioned, but this is a script name where no underlines are allowed. I’d guess VimL is just an abbreviation for Vim Language (Vim script). It was probably coined some … Read more
http://www.justsoftwaresolutions.co.uk/cplusplus/rvalue_references_and_perfect_forwarding.html Why is this useful? Well, it means that a function template can pass its arguments through to another function whilst retaining the lvalue/rvalue nature of the function arguments by using std::forward. This is called “perfect forwarding”, avoids excessive copying, and avoids the template author having to write multiple overloads for lvalue and rvalue references.
Converting an object in memory into a format that can be written to disk, or sent over the wire, etc. Wikipedia’s description.
In C++, every name has its scope outside which it doesn’t exist. A scope can be defined by many ways : it can be defined by namespace, functions, classes and just { }. So a namespace, global or otherwise, defines a scope. The global namespace refers to using ::, and the symbols defined in this … Read more
I + (some 18 characters) + N = InternationalizatioN I18N safe means that steps were taken during design and development that will facilitate Localization (L10N) at a later point.
