\chapterprecishere{``Caution! Under no circumstances confuse the adjective \emph{basic} with the noun \emph{BASIC}, except under confusing circumstances!''\par\raggedleft --- \textup{\tbas\ Reference Manual, \theedition}\footnote{Original quotation is from \emph{The INTERCAL Programming Language Reference Manual} by Donald R. Woods and James M. Lyon}}
|
||||
|
||||
This chapter describes the basic concepts of the \tbas\ language.
|
||||
|
||||
|
||||
\section{Values and Types}
|
||||
\label{valuesandtypes}
|
||||
|
||||
BASIC is a \emph{Dynamically Typed Language}, which means variables do not know which group they should barge in; only values of the variable do. In fact, there is no type definition in the language: \emph{we do want our variables to feel themselves awkward.}
|
||||
|
||||
There are six basic types: \emph{number}, \emph{boolean}, \emph{string}, \emph{array}, \emph{generator} and \emph{function}.
|
||||
|
||||
\emph{Number} represents real (double-precision floating-point or \emph{actually rational}) numbers. Operations on numbers follow the same rules of the underlying virtual machine\footnote{if you are not a computer person, just disregard}, and such machines must follow the IEEE 754 standard\footnote{ditto.}.
|
||||
|
||||
\emph{Boolean} is the type of the values that is either \codebf{TRUE} or \codebf{FALSE}. Number \codebf{0} and \codebf{FALSE} makes condition \emph{false}. When used in numeric context, \codebf{FALSE} will be interpreted as 0 and \codebf{TRUE} as 1.
|
||||
|
||||
\emph{String} represents immutable\footnote{cannot be altered directly} sequences of bytes. However, you can't weave them to make something like \emph{string array}\footnote{future feature\ldots\ maybe\ldots? Probably not\ldots}.
|
||||
|
||||
\emph{Array} represents collection of numbers in 1- or more dimensions.
|
||||
|
||||
\emph{Generator} represents a value that automatically counts up/down whenever they have been called in For-Next loop.
|
||||
|
||||
\emph{Functions} are, well\ldots\ functions\footnote{This is not a closure; there is no way you can define a local- or anonymous variable in BASIC.}, especially user-defined ones. Functions are \emph{type} because some built-in functions will actually take \emph{functions} as arguments.
|
||||
|
||||
\section{Control Flow}
|
||||
|
||||
A program is executed starting with its lowest line number. Statements on a line are executed from left to right. When all Statements are finished execution, next lowest line number will be executed. Control flow functions can modify this normal flow.
|
||||
|
||||
You can dive into other line in the middle of the program with \code{GOTO}. The program flow will continue normally at the new line \emph{and it will never know ya just did that}.
|
||||
|
||||
If you want less insane jumping, \code{GOSUB} is used to jump to a subroutine. Subroutine is a little section of a code that serves as a tiny program inside of a program. \code{GOSUB} will remember from which statement in the line you have came from, and will return your program flow to that line when \code{RETURN} statement is encountered. (of course, if \code{RETURN} is used without \code{GOSUB}, program will raise some error) Do note that while you can reserve some portion of a program line as a \code{subroutine}, \tbas\ will not provide local variables and whatnot as all variables in \tbas\ are global, and you can just \code{GOTO} out of a subroutine to anywhere you desire and wreak havoc \emph{if you really want to}.
|
||||
|
||||
The \code{ON} statement provides alternative branching construct. You can enter multiple line numbers and let your variable (or mathematical expression) to choose which index of line numbers to \code{GOTO}- or \code{GOSUB} into.
|
||||
|
||||
The \code{IF-THEN-ELSE} lets you to conditionally select which of the two branches to execute.
|
||||
|
||||
The \code{FOR-NEXT} lets you to loop a portion of a program while automatically counting your chosen variable up or down.

\label{functions}
|
||||
|
||||
Functions are a form of expression that may taks input arguments surrounded by parentheses. Most of the traditional BASIC \emph{statements} that does not return a value are \emph{functions} in \tbas , and like those, while \tbas\ functions can be called without parentheses, it is highly \emph{discouraged} because of the ambiguities in syntax. \textbf{Always use parentheses on function call!}

|
||||
\subsection{READ}
|
||||
\codeline{\textbf{READ} VARIABLE}\par
|
||||

\section[Currying]{Haskell Curry Wants to Know Your Location}
|
||||
\label{currying101}
|
||||
|
||||
So what the fsck is currying? Consider the following code:
|
||||
|
||||
\begin{lstlisting}
|
||||
10 DEFUN F(K,T)=ABS(T)==K
|
||||
20 CF=F<~32
|
||||
30 PRINT CF(24) : REM will print 'false'
|
||||
40 PRINT CF(-32) : REM will print 'true'
|
||||
\end{lstlisting}
|
||||
|
||||
% NOTE: you can't use \basiccurry within \code{}
|
||||
Here, \code{CF} is a curried function of \code{F}; built-in operator \code{$<\!\sim$} applies \code{32} to the first parameter of the function \code{F}, which dynamically returns a \emph{function} of \code{CF(T) = ABS(T) == 32}. The fact that Curry Operator returns a \emph{function} opens many possibilities, for example, you can create loads of sibling functions without making loads of duplicate codes.
|
||||
|
||||
\section[Wrapping-Up]{The Grand Unification}
|
||||
|
||||
Using all the knowledge we have learned, it should be trivial\footnote{/s} to write a Quicksort function in \tbas, like this:
|
||||

10 DEFUN LESS(P,X)=X<P
|
||||
11 DEFUN GTEQ(P,X)=X>=P
|
||||
12 DEFUN QSORT(XS)=IF LEN(XS)<1 THEN NIL ELSE
|
||||
QSORT(FILTER(LESS<~HEAD(XS),TAIL(XS))) # HEAD(XS)!NIL #
|
||||
QSORT(FILTER(GTEQ<~HEAD(XS),TAIL(XS)))

Line 12 implements quicksort algorithm, using \code{LESS} and \code{GTEQ} as helper functions. \code{LESS} is a user-function version of less-than operator, and \code{GTEQ} is similar. \code{QSORT} selects a pivot by taking the head-element of the array \code{XS}\footnote{stands for \emph{X's}} with \code{HEAD(XS)}, then utilises curried version of \code{LESS} and \code{GTEQ} to move lesser-than-pivot values to the left and greater to the right (the head element itself does not get recursed, here \code{TAIL(XS)} is applied to make head-less copy of the array), and these two separated \emph{chunks} are recursively sorted using the same \code{QSORT} function. Currying is exploited to give comparison functions a pivot-value to compare against, and also because \code{FILTER} wants a \emph{function} and not an \emph{expression}. \code{HEAD(XS)!NIL} creates a single-element array contains head-element of the \code{XS}.
|
||||
|
||||
%Uncomment this if you finally decided to support a closure%
|
||||
%% Using \emph{closure}, the definition of \code{QSORT} can truly be a one-liner and be \emph{even more cryptic}:
|
||||
%%
|
||||
%% \begin{lstlisting}
|
||||
%% 10 QSORT=[XS]~>IF LEN(XS)<1 THEN NIL ELSE
|
||||
%% QSORT(FILTER([K]~>K<HEAD XS,TAIL XS)) # HEAD(XS)!NIL #
|
||||
%% QSORT(FILTER([K]~>K>=HEAD XS,TAIL XS))
|
||||
%% \end{lstlisting}

\newcommand{\intrange}{\hl{[$0..2^{53}-1$]}}
|
||||
|
||||
This chapter describes the \tbas\ language.
|
||||
|
||||
\section{Metasyntax}
|
||||
|
||||
In the descriptions of BASIC syntax, these conventions apply.
|
||||
|
||||
\begin{itemlist}
|
||||
\item \codebf{VERBATIM} --- Type exactly as shown
|
||||
\item \code{IDENTIFIER} --- Replace \emph{identifier} with appropriate metavariable
|
||||
\item \code{[a]} --- Words within square brackets are optional
|
||||
\item \code{\{a|b\}} --- Choose either \code{a} or \code{b}
|
||||
\item \code{[a|b]} --- Optional version of above
|
||||
\item \code{a\ldots} --- The preceding entity can be repeated
|
||||
\end{itemlist}
|
||||
|
||||
\section{Definitions}
|
||||
|
||||
A \emph{Program Line} consists of a line number followed by a \emph{Statements}. Program Lines are terminated by a line break or by the end-of-the-file.
|
||||
|
||||
A \emph{Line Number} is an integer within the range of \intrange.
|
||||
|
||||
A \emph{Statement} is special form of code which has special meaning. A program line can be composed of 1 or more statements, separated by colons. For the details of statements available in \tbas , see \ref{statements}.
|
||||
|
||||
\codeline{STATEMENT [: STATEMENT]\ldots}
|
||||
|
||||
An \emph{Expression} is rather normal program lines, e.g. mathematical equations and function calles. The expression takes one of the following forms. For the details of functions available in \tbas , see \ref{functions}.
|
||||
|
||||
\codeline{VARIABLE\_OR\_FUNCTION}\\
|
||||
\codeline{( EXPRESSION )}\\
|
||||
\codeline{\textbf{IF} EXPRESSION \textbf{THEN} EXPRESSION [\textbf{ELSE} EXPRESSION]}\\
|
||||
\codeline{FUNCTION \textbf{(} [EXPRESSION \{\textbf{,}|\textbf{;}\} [\{\textbf{,}|\textbf{;}\}]] \textbf{)}}\\
|
||||
\codeline{FUNCTION [EXPRESSION \{\textbf{,}|\textbf{;}\} [\{\textbf{,}|\textbf{;}\}]]}\\
|
||||
\codeline{EXPRESSION BINARY\_OPERATOR EXPRESSION}\\
|
||||
\codeline{UNARY\_OPERATOR EXPRESSION}
|
||||
|
||||
An \emph{Array} takes following form:
|
||||
|
||||
\codeline{ARRAY\_NAME \textbf{(} EXPRESSION [\textbf{,} EXPRESSION]\ldots\ \textbf{)}}
|
||||
|
||||
\section{Literals}
|
||||
\subsection{String Literals}
|
||||
|
||||
String literals take the following form:
|
||||
|
||||
\codeline{\textbf{"} [CHARACTERS] \textbf{"}}
|
||||
|
||||
where \code{CHARACTERS} is a 0 or more repetition of ASCII-printable letters.\footnote{In other words, \code{0x20..0x7E}}
|
||||
|
||||
To print out graphical letters outside of ASCII-printable, use string concatenation with \code{CHR} function, or use \code{EMIT} function.
|
||||
|
||||
\subsection{Numeric Literals}
|
||||
|
||||
Numeric literals take one of the following forms:
|
||||
|
||||
\codeline{[\textbf{+}|\textbf{-}][\textbf{0}|\textbf{1}|\textbf{2}|\textbf{3}|\textbf{4}|\textbf{5}|\textbf{6}|\textbf{7}|\textbf{8}|\textbf{9}]\ldots\ [\textbf{.}][\textbf{0}|\textbf{1}|\textbf{2}|\textbf{3}|\textbf{4}|\textbf{5}|\textbf{6}|\textbf{7}|\textbf{8}|\textbf{9}]\ldots}\\
|
||||
\codeline{\textbf{0}\{\textbf{x}|\textbf{X}\}[\textbf{0}|\textbf{1}|\textbf{2}|\textbf{3}|\textbf{4}|\textbf{5}|\textbf{6}|\textbf{7}|\textbf{8}|\textbf{9}]\ldots}\\
|
||||
\codeline{\textbf{0}\{\textbf{b}|\textbf{B}\}[\textbf{0}|\textbf{1}|\textbf{2}|\textbf{3}|\textbf{4}|\textbf{5}|\textbf{6}|\textbf{7}|\textbf{8}|\textbf{9}]\ldots}
|
||||
|
||||
Hexadecimal and binary literals are always interpreted as \emph{unsigned} integers. They must range between \intrange.
|
||||
|
||||
\subsection{Variables}
|
||||
|
||||
Variable names must start with a letter and all characters of the name must be letters \code{A-Z}, figures \code{0-9}. Variable names must not be identical to reserved words, but may \emph{contain} one. Variable names are case-insensitive.
|
||||
|
||||
Unlike conventional BASIC dialects (especially GW-BASIC), name pool of variables are shared between all the types. For example, if you have a numeric variable \code{A}, and define an array named \code{A} later in the program, the new array will overwrite your numeric \code{A}.
|
||||
|
||||
Furthermore, \emph{sigils} are not used in the \tbas\ and attempting to use one will raise syntax-error or undefined behaviour.
|
||||
|
||||
\subsection{Types}
|
||||
|
||||
Types of data recognised by \tbas\ are distinguished by some arcane magic of Javascript auto-casing mumbo-jumbo
|
||||
|
||||
\begin{tabulary}{\textwidth}{rCL}
|
||||
Type & Range & Precision \\
|
||||
\hline
|
||||
String & As many as the machine can handle & \, \\
|
||||
Integer & $ \pm 2^{53}-1 $ & exact within the range \\
|
||||
Float & $ \pm 4.9406564584124654 \times 10^{-324} $ -- $ \pm 1.7976931348623157 \times 10^{308} $ & about 16 significant figures \\
|
||||
\end{tabulary}
|
||||
|
||||
\section{Operators}
|
||||
\subsection{Order of Precedence}
|
||||
|
||||
The order of precedence of the operators is as shown below, lower numbers means they have higher precedence (more tightly bound)
|
||||
|
||||
\begin{longtable}{*{2}{m{\textwidth}}}\hline

\end{tabulary}
|

\end{longtable}
|
||||
|
||||
\subsubsection*{Examples}
|
||||
\begin{itemlist}
|
||||
\item Exponentiation is more tightly bound than negation: \code{-1\basicexp 2 == -(1\basicexp 2) == -1} but \code{(-1)\basicexp 2 == 1}
|
||||
\item Exponentiation is right-associative: \code{4\basicexp 3\basicexp 2 == 4\basicexp (3\basicexp 2) == 262144}. This behaviour is \emph{different} from GW-BASIC in which its exponentiation is left-associative.
|
||||
\end{itemlist}
|
||||
|
||||
\subsection{Mathematical Operators}
|
||||
|
||||
Mathematical operators operate on expressions that returns numeric value only, except for the \code{+} operator which will take the action of string concatenation if either of the operand is non-numeric.
|
||||
|
||||
\begin{tabulary}{\textwidth}{clL}
|
||||
Code & Operation & Result \\
|
||||
\hline
|
||||
\emph{x} $=$ \emph{y} & Assignment & Assigns \emph{y} into \emph{x} \\
|
||||
\emph{x} $\basicexp$ \emph{y} & Exponentiation & \emph{x} raised to the \emph{y}th power \\
|
||||
\emph{x} $\ast$ \emph{y} & Multiplication & Product of \emph{x} and \emph{y} \\
|
||||
\emph{x} $/$ \emph{y} & Division & Quotient of \emph{x} and \emph{y} \\
|
||||
\emph{x} $\backslash$ \emph{y} & Truncated Division & Integer quotient of \emph{x} and \emph{y} \\
|
||||
\emph{x} \condensedfont{MOD} \emph{y} & Modulo & Integer remainder of \emph{x} and \emph{y} with sign of \emph{x} \\
|
||||
\emph{x} $+$ \emph{y} & Addition & Sum of \emph{x} and \emph{y} \\
|
||||
\emph{x} $-$ \emph{y} & Subtraction & Difference of \emph{x} and \emph{y} \\
|
||||
$+$ \emph{x} & Unary Plus & Value of \emph{x} \\
|
||||
$-$ \emph{x} & Unary Minus & Negative value of \emph{x} \\
|
||||
\emph{x} \condensedfont{MIN} \emph{y} & Minimum & Lesser value of two \\
|
||||
\emph{x} \condensedfont{MAX} \emph{y} & Maximum & Greater value of two \\
|
||||
|
||||
\end{tabulary}
|
||||
|
||||
\subsubsection*{Notes}
|
||||
\begin{itemlist}
|
||||
\item Type conversion rule follows underlying Javascript implementation. In other words, \emph{only the god knows.}
|
||||
\item The expression \code{0\basicexp 0} will return \code{1}, even though the expression is indeterminant.
|
||||
\end{itemlist}
|
||||
|
||||
\subsubsection*{Errors}
|
||||
\begin{itemlist}
|
||||
\item Any expression that results \code{NaN} or \code{Infinity} in Javascript will return some kind of errors, mainly \code{Division by zero}.
|
||||
\item If \code{\emph{x}<0} and \code{\emph{y}} is not integer, \code{\emph{x}\basicexp\emph{y}} will raise \code{Illegal function call}.
|
||||
\end{itemlist}
|
||||
|
||||
\subsection{Comparison Operators}
|
||||
|
||||
Comparison operator can operate on numeric and string operands. String operands will be automatically converted to numeric value if they can be; if one operand is numeric and other is non-numeric string, the former will be converted to string value.
|
||||
|
||||
\begin{tabulary}{\textwidth}{clL}
|
||||
Code & Operation & Result \\
|
||||
\hline
|
||||
\emph{x} == \emph{y} & Equal & True if \emph{x} equals \emph{y} \\
|
||||
\emph{x} <\!> \emph{y} \quad \emph{x} >\!< \emph{y} & Not equal & False if \emph{x} equals \emph{y} \\
|
||||
\emph{x} < \emph{y} & Less than & True if \emph{x} is less than \emph{y} \\
|
||||
\emph{x} > \emph{y} & Greater than & True if \emph{x} is greater than \emph{y} \\
|
||||
\emph{x} <\!= \emph{y} \quad \emph{x} =\!< \emph{y} & Less than or equal & False if \emph{x} is greater than \emph{y} \\
|
||||
\emph{x} >\!= \emph{y} \quad \emph{x} =\!> \emph{y} & Greater than or equal & False if \emph{x} is less than \emph{y} \\
|
||||
\end{tabulary}
|
||||
|
||||
When comparing strings, the ordering is as follows:
|
||||
|
||||
\begin{itemlist}
|
||||
\item Two strings are equal only when they are of the same length and every codepoint of the first string is identical to that of the second. This includes any whitespace or unprintable characters.
|
||||
\item Each character position of the string is compared starting from the leftmost character. When a pair of different characters is encountered, the string with the character of lesser codepoint is less than the string with the character of greater codepoint.
|
||||
\item If the strings are of different length, but equal up to the length of the shorter string, then the shorter string is less than the longer string.
|
||||
\end{itemlist}
|
||||
|
||||
\subsection{Bitwise Operators}
|
||||
|
||||
Bitwise operators operate on unsigned integers only. Floating points are truncated\footnote{truncated towards zero} to integers.
|
||||
|
||||
\begin{tabulary}{\textwidth}{clL}
|
||||
Code & Operation & Result \\
|
||||
\hline
|
||||
\emph{x} <\!< \emph{y} & Bitwise Shift Left & Shifts entire bits of \emph{x} by \emph{y} \\
|
||||
\emph{x} >\!> \emph{y} & Bitwise Shift Right & Shift entire bits \emph{x} by \emph{y}, including sign bit \\
|
||||
\condensedfont{BNOT} \emph{x} & Ones' complement & $-\emph{x}-1$ \\
|
||||
\emph{x} \condensedfont{BAND} \emph{y} & Bitwise conjunction & Bitwise AND of \emph{x} and \emph{y} \\
|
||||
\emph{x} \condensedfont{BOR} \emph{y} & Bitwise disjunction & Bitwise OR of \emph{x} and \emph{y} \\
|
||||
\emph{x} \condensedfont{BXOR} \emph{y} & Bitwise add-with-no-carry & Bitwise XOR of \emph{x} and \emph{y} \\
|
||||
\end{tabulary}
|
||||
|
||||
\subsection{Boolean Operators}
|
||||
|
||||
Boolean operators operate on boolean values. If one of the operand is not boolean, it will be cast to appropriate boolean value. See \ref{valuesandtypes} for casting rules.
|
||||
|
||||
\begin{tabulary}{\textwidth}{clL}
|
||||
Code & Operation & Result \\
|
||||
\hline
|
||||
\condensedfont{NOT} \emph{x} & Logical negation & True if \emph{x} is false and vice versa \\
|
||||
\emph{x} \condensedfont{AND} \emph{y} & Bitwise conjunction & True if \emph{x} and \emph{y} are both true \\
|
||||
\emph{x} \condensedfont{OR} \emph{y} & Bitwise disjunction & True if \emph{x} or \emph{y} is true, or both are true \\
|
||||
\end{tabulary}
|
||||
|
||||
\subsection{Generator Operators}
|
||||
|
||||
Generator operators operate on numeric values and generators to create and modify a generator.
|
||||
|
||||
\begin{tabulary}{\textwidth}{clL}
|
||||
Code & Result \\
|
||||
\hline
|
||||
\emph{x} \condensedfont{TO} \emph{y} & Creates an generator that counts from \emph{x} to \emph{y} \\
|
||||
\emph{x} \condensedfont{STEP} \emph{y} & Modifies an counting stride of the generator \emph{x} into \emph{y} \\
|
||||
\end{tabulary}
|
||||
|
||||
\subsection{Array Operators}
|
||||
|
||||
Array operators operate on arrays and numeric values.
|
||||
|
||||
\begin{tabulary}{\textwidth}{clL}
|
||||
Code & Operation & Result \\
|
||||
\hline
|
||||
\emph{x} $!$ \emph{y} & Cons & Prepends a value of \emph{x} into an array of \emph{y} \\
|
||||
\emph{x} $\sim$ \emph{y} & Push & Appends a value of \emph{y} into an array of \emph{x} \\
|
||||
\emph{x} $\#$ \emph{y} & Concat & Concatenates two arrays \\
|
||||
\end{tabulary}
|
||||
|
||||
Arbitrary arrays can be constructed using empty-array constant \codebf{NIL}.
|
||||
|
||||
\subsection{Function Operators}
|
||||
|
||||
Function operators operate on functions and some values.
|
||||
|
||||
\begin{tabulary}{\textwidth}{clL}
|
||||
Code & Operation & Result \\
|
||||
\hline
|
||||
\emph{f} \basiccurry\ \emph{x} & Curry & Apply \emph{x} into the first parameter of the function \emph{f} \\
|
||||
%{[}\emph{x},\,\emph{y}\ldots{]} \basicclosure\ \emph{e} & Closure & Creates a closure (anonymous function) from one or more parameters \emph{x},\,\emph{y}\ldots\ and an expression \emph{e} \\
|
||||
\end{tabulary}
|
||||
|
||||
\emph{Currying} is an operation that returns new function that has given value applied to the original function's first parameter. See \ref{currying101} for tutorials.
|
||||
|
||||
\section{Syntax In EBNF}
|
||||
|
||||
If you're \emph{that} into the language theory of computer science, texts above are just waste of bytes/inks/pixel-spaces/whatever; this little section should be more than enough!

|

\label{statements}
|
||||
|
||||
A Program line is composed of a line number and one or more statements. Multiple statements are separated by colons \code{:}.
|
||||
|
||||
\section{IF}
|
||||
|
||||
\codeline{\textbf{IF} TRUTH\_VALUE \textbf{THEN} TRUE\_EXPRESSION [\textbf{ELSE} FALSE\_EXPERSSION]}
|
||||
|
||||
If \code{TRUTH\_VALUE} is truthy, executes \code{TRUE\_EXPRESSION}. If \code{TRUTH\_VALUE} is falsy and \code{FALSE\_EXPERSSION} is specified, executes that expression; otherwise next line or next statement will be executed.
|
||||
|
||||
\subsubsection*{Notes}
|
||||
|
||||
\begin{itemlist}
|
||||
\item \codebf{IF} is both statement and expression. You can use IF-clause after \codebf{ELSE}, or within functions as well, for example.
|
||||
\item \codebf{THEN} is \emph{not} optional, this behaviour is different from most of the BASIC dialects.
|
||||
\item Also unlike the most dialects, \codebf{GOTO} cannot be omitted; doing so will make the number be returned to its parent expression.
|
||||
\end{itemlist}
|
||||
|
||||
\section{ON}
|
||||
|
||||
\codeline{\textbf{ON} INDEX\_EXPRESSION \{\textbf{GOTO}|\textbf{GOSUB}\} LINE0 [\textbf{,} LINE1]\ldots}
|
||||
|
||||
Jumps to the line number returned by the \code{INDEX\_EXPRESSION}. If the result is outside of range of the arguments, no jump will be performed.
|
||||
|
||||
\subsubsection*{Parameters}
|
||||
|
||||
\begin{itemlist}
|
||||
\item \code{LINEn} can be a number, numeric expression (aka equations) or a line label.
|
||||
\item When \code{OPTIONBASE 1} is used within the program, \code{LINEn} starts from 1 instead of 0.
|
||||
\end{itemlist}
|
||||
|
||||
\section{DEFUN}
|
||||
|
||||
\emph{There it is, the} DEFUN. \emph{All those new-fangled parser\footnote{a computer program that translates program code entered by you into some data bits that only it can understand} and paradigms\footnote{a guidance to in which way you must think to assimilate your brain into the computer-overlord} are tied to this very statement on \tbas, and only Wally knows its secrets\ldots}
|
||||
|
||||
\codeline{\textbf{DEFUN} NAME \textbf{(} [ARGS0 [\textbf{,} ARGS1]\ldots] \textbf{)} \textbf{=} EXPRESSION }
|
||||
|
||||
With the aid of other statements\footnote{Actually, only the IF is useful, unless you want to \emph{transcend} from the \emph{dung} of mortality by using DEFUN within DEFUN (a little modification of the source code is required)} and functions, DEFUN will allow you to ascend from traditional BASIC and do godly things such as \emph{recursion}\footnote{see recursion} and \emph{functional programming}.
|
||||
|
||||
Oh, and you can define your own function, in traditional \code{DEF FN} sense.
|
||||
|
||||
\subsubsection*{Parameters}
|
||||
|
||||
\begin{itemlist}
|
||||
\item \code{NAME} must be a valid variable name.
|
||||
\item \code{ARGSn} must be valid variable names, but can be a name of variables already used within the BASIC program; their value will not be affected nor be used.

\section{Resolving Variables}
|
||||
|
||||
This section describes all use cases of \code{BasicVar}.
|
||||
|
||||
When a variable is \code{resolve}d, an object with instance of \code{BasicVar} is returned. A \code{bvType} of Javascript value is determined using \code{JStoBASICtype}.
|
||||
|
||||
\begin{tabulary}{\textwidth}{R|LL}
|
||||
Typical User Input & TYPEOF(\textbf{Q}) & Instanceof \\
|
||||
\hline
|
||||
\code{\textbf{Q}=42.195} & {\ttfamily num} & \emph{primitive} \\
|
||||
\code{\textbf{Q}=42>21} & {\ttfamily boolean} & \emph{primitive} \\
|
||||
\code{\textbf{Q}="BASIC!"} & {\ttfamily string} & \emph{primitive} \\
|
||||
\code{\textbf{Q}=DIM(12)} & {\ttfamily array} & Array (JS) \\
|
||||
\code{\textbf{Q}=1 TO 9 STEP 2} & {\ttfamily generator} & ForGen \\
|
||||
\code{DEFUN \textbf{Q}(X)=X+3} & {\ttfamily usrdefun} & BasicAST \\
|
||||
\end{tabulary}
|
||||
|
||||
\subsection*{Notes}
|
||||
\begin{itemlist}
|
||||
\item \code{TYPEOF(\textbf{Q})} is identical to the variable's bvType; the function simply returns \code{BasicVar.bvType}.
|
||||
\item Do note that all resolved variables have \code{troType} of \code{Lit}, see next section for more information.
|
||||
\end{itemlist}
|
||||
|
||||
\section{Unresolved Values}
|
||||
|
||||
Unresolved variables has JS-object of \code{troType}, with \emph{instanceof} \code{SyntaxTreeReturnObj}. Its properties are defined as follows:
|
||||
|
||||
\begin{tabulary}{\textwidth}{RL}
|
||||
Properties & Description \\
|
||||
\hline
|
||||
{\ttfamily troType} & Type of the TRO (Tree Return Object) \\
|
||||
{\ttfamily troValue} & Value of the TRO \\
|
||||
{\ttfamily troNextLine} & Pointer to next instruction, array of: [\#line, \#statement] \\
|
||||
\end{tabulary}
|
||||
|
||||
Following table shows which BASIC object can have which \code{troType}:
|
||||
|
||||
\begin{tabulary}{\textwidth}{RLL}
|
||||
BASIC Type & troType \\
|
||||
\hline
|
||||
Any Variable & {\ttfamily lit} \\
|
||||
Boolean & {\ttfamily bool} \\
|
||||
Generator & {\ttfamily generator} \\
|
||||
Array & {\ttfamily array} \\
|
||||
Number & {\ttfamily num} \\
|
||||
String & {\ttfamily string} \\
|
||||
DEFUN'd Function & {\ttfamily internal\_lambda} \\
|
||||
Array Indexing & {\ttfamily internal\_arrindexing\_lazy} \\
|
||||
Assignment & {\ttfamily internal\_assignment\_object} \\
|
||||
\end{tabulary}
|
||||
|
||||
\subsection*{Notes}
|
||||
\begin{itemlist}
|
||||
\item All type that is not \code{lit} only appear when the statement returns such values, e.g. \code{internal\_lambda} only get returned by DEFUN statements as the statement itself returns defined function as well as assign them to given BASIC variable.
|
||||
\item As all variables will have \code{troType} of \code{lit} when they are not resolved, the property must not be used to determine the type of the variable; you must \code{resolve} it first.
|
||||
\item The type string \code{function} should not appear outside of TRO and \code{astType}; if you do see them in the wild, please check your JS code because you probably meant \code{usrdefun}.

||||

# Syntax
|
||||
## Reserved directories
|
||||
* `$DEVICE<device_number>`
|
||||
|
||||
## Reserved files
|
||||
* `$DEVICE<device_number>/$BOOT` — associates to bootloader, exact filename depends on the filesystem the device uses
|
||||
|
||||
# Drivers
|
||||
Filesystem driver is just an executable that can do file I/O to one specific filesystem it supports.
|
||||
|
||||
Filesystem drivers, just as regular TVDOS drivers, resides in `<root>/TVDOS/DRIVERS/`
|
||||
|
||||
# Commands

||||
## cp
|
||||
`[cp|copy] <source> <destination>`
|
||||
|
||||
Executes following command:
|
||||
```
|
||||
<filesystem>.fs cp <source> <dest>
|
||||
```

||||
|
||||
## mv
|
||||
`[mv|move] <from> <to>`
|
||||
|
||||
Executes following command:
|
||||
```
|
||||
<filesystem>.fs mv <from> <to>
