Webel's "super-relational" Note pages!

A Note is a short categorised statement, claim, policy, tip, or issue tracker Throughout this site, content is often related to supporting Notes, and each Note page links back to the content pages that reference it! The Note and Snippet concepts are very closely related and they support each other.
Look for "super-relational" Note page links at the bottom of most content pages!

CAVEAT, ISSUE, LIMITATION, TOOL Mathematica: Wolfram Player Pro 13.1: NotebookDelete[] does not work Wolfram, Mathematica, Wolfram Player Pro
ASSERTION, TIP Mathematica: Webel: You get compelling incremental value out of Mathematica even if you don't yet command all of the syntax and massive powers of the Wolfram Language! Wolfram Language, Wolfram, functional, functional programming, object-oriented, ADTs, Abstract Data Types, Mathematica, symbolic algebra
NAMING, OPTION, PATTERN, TIP Mathematica: Webel: You CAN/MAY use $ in variable names and function names - just not as the first character before a Capital - and it's extremely useful. You won't get sent to Azkaban prison if do you use a $ character! Wolfram, Mathematica, Mathematica:Entity, Wolfram Language, notation
TIP Mathematica: Webel: ADT pseudo classes: TIP: Prefer the Decorator Pattern over multiple inheritance of ADT-Method UpValues! (But not because "inheritance is evil", it isn't.) Mathematica, ADTs, Wolfram, Wolfram Language, Abstract Data Types, WebelADT, object-oriented, OO, OOP, functional, functional programming, stateless functional, Webel:ADT:MemberInterface, Decorator Pattern, multiple inheritance, inheritance
POLICY Mathematica: Webel: ADT pseudo classes: There is an 'ADT' universal base class that has no supers. It "blesses" every other sub-class ADT by populating it with some common ADT-method UpValues against its signature pattern via the 'adt$def$All[]' definer. Mathematica, ADTs, Wolfram, Wolfram Language, Abstract Data Types, WebelADT, object-oriented, OO, OOP, functional, functional programming, stateless functional, Webel:ADT:All, Webel:ADT, Mathematica::UpValue
EXPLANATION Mathematica: Webel: ADT pseudo classes: The term 'Abstract Data Types (ADTs)' is used informally (the ADTs do not always adhere to strict mathematical definitions of ADTs). Just please think of it here as meaning a "strong type" for Mathematica. Mathematica, ADTs, Wolfram, Wolfram Language, Abstract Data Types, WebelADT, object-oriented, OO, OOP, functional, functional programming
POLICY Mathematica: Webel: ADT pseudo classes: POLICY: The expression '$$' is reserved as the primary named parameter for the defining pattern of all ADT classes that extend the universal base 'ADT' class. Mathematica, ADTs, Wolfram, Wolfram Language, Abstract Data Types, WebelADT
CONVENTION, NAMING, POLICY Mathematica: Webel: ADT pseudo classes: POLICY: The ADT-Methods of an ADT-Class are created as TagSetDelayed UpValues using the 'signature' of the ADT-Class and its defining 'pattern' as 1st argument Mathematica, ADTs, Wolfram, Wolfram Language, Abstract Data Types, WebelADT, object-oriented, OO, OOP, functional, functional programming, stateless functional, Webel:ADT, Webel:ADT:Definer
CONVENTION, POLICY Mathematica: Webel: ADT pseudo classes: POLICY: The Abstract Data Types (ADTs) are stateless functional (although inheritance and overrides are supported), with no caching by default (although there is nice optional caching using CreateUUID[] and Once[]). Mathematica, ADTs, Wolfram, Wolfram Language, Abstract Data Types, WebelADT, object-oriented, OO, OOP, functional, functional programming, stateless functional
CONVENTION, POLICY Mathematica: Webel: ADT pseudo classes: POLICY: Every named concrete Abstract Data Type (ADT) class has a ONE unique "signature" (which is the pattern passed to the "definer" functions). To vary a signature, define another unique ADT class name. Mathematica, ADTs, Wolfram, Wolfram Language, Abstract Data Types, WebelADT, object-oriented, OO, OOP, functional, functional programming, stateless functional
POLICY Mathematica: Webel: ADT pseudo classes: POLICY: Definer functions MUST return the self-declared or injected 'pattern' that determines the unique "ADT-signature" of the defined ADT class. Mathematica, ADTs, Wolfram, Wolfram Language, Abstract Data Types, WebelADT, object-oriented, OO, OOP, functional, functional programming, stateless functional, Webel:ADT, Webel:ADT:Definer, Webel:ADT:signature
CONVENTION, NAMING, POLICY Mathematica: Webel: ADT pseudo classes: POLICY/DEFINITION: Every "hard coded" definer or defining client of a definer has a corresponding ADT ArchetypeClass. Example ("hard coded"): The definer 'my$def$MY$SmartList' has ArchetypeClass 'MY$SmartList'. Mathematica, ADTs, Wolfram, Wolfram Language, Abstract Data Types, WebelADT, object-oriented, OO, OOP, functional, functional programming, stateless functional, Webel:ADT:Class, Webel:ADT:Definer, singleton, Webel:ADT:ArchetypeClass
CONVENTION, NAMING, POLICY Mathematica: Webel: ADT pseudo classes: DEFINITION/CONVENTION: Functions that populate ADTs with reusable ADT-method UpValues are called 'definers' and include '$def' in the name after a Package scope indicator: Example: adt$def$ADT, my$def$MY$CleverList Mathematica, ADTs, Wolfram, Wolfram Language, Abstract Data Types, WebelADT, object-oriented, OO, OOP, functional, functional programming, stateless functional, Webel:ADT, Webel:ADT:Definer
CONVENTION, NAMING, POLICY Mathematica: Webel: ADT pseudo classes: CONVENTION: PROVISIONAL: The infix operator for calling ADT-Methods on ADT "objects" is the CircleDot (⊙ in Notebooks). ISSUE: \[CircleDot] is NOT GOOD FOR USE IN IDEs! Mathematica, ADTs, Wolfram, Wolfram Language, Abstract Data Types, WebelADT, object-oriented, OO, OOP, functional, functional programming, stateless functional, Webel:ADT:Class, Webel:ADT:Definer, singleton, Webel:ADT:infix, Webel:ADT:Object
CONVENTION, TIP Mathematica: Webel: A concise i:/o: notation is often used for indicating input/output cells in Mathematica notebooks in Webel's online help pages and tutorials, instead of 'In[n]:=' and 'Out[n]='. (Also learn how to hide them completely in notebooks.) Wolfram, Mathematica, Wolfram Language, Mathematica:notebook
CONVENTION, POLICY, TIP Mathematica: Webel ADT pseudo classes: A tricky POLICY & CONVENTION: Client packages MUST access the special "wrapped" primary named ADT-parameter '$$' via $ContextAliases! The recommended alias is "A`" (which stands of course for ADT). Mathematica, ADTs, Wolfram, Wolfram Language, Abstract Data Types, WebelADT, object-oriented, OO, OOP, functional, functional programming, stateless functional, Webel:ADT:Class, Webel:ADT, Webel:ADT:A`, Mathematica:$ContextAliases

CONVENTION, NAMING Mathematica: NAMING CONVENTION: Webel: ADT pseudo classes: An UpValue that can be invoked on an ADT accepting its unique 'signature' pattern as (at least) 1st argument is called an "ADT-method"'.
