/*
|
|
|
|
|
* TADS3 is a language designed by Michael J. Roberts for the writing of text
|
|
|
|
|
* based games. TADS comes from Text Adventure Development System. It has good
|
|
|
|
|
* support for the processing and outputting of formatted text and much of a
|
|
|
|
|
* TADS program listing consists of strings.
|
|
|
|
|
*
|
|
|
|
|
* TADS has two types of strings, those enclosed in single quotes (') and those
|
|
|
|
|
* enclosed in double quotes ("). These strings have different symantics and
|
|
|
|
|
* can be given different highlighting if desired.
|
|
|
|
|
*
|
|
|
|
|
* There can be embedded within both types of strings html tags
|
|
|
|
|
* ( <tag key=value> ), library directives ( <.directive> ), and message
|
|
|
|
|
* parameters ( {The doctor's/his} ).
|
|
|
|
|
*
|
|
|
|
|
* Double quoted strings can also contain interpolated expressions
|
|
|
|
|
* ( << rug.moved ? ' and a hole in the floor. ' : nil >> ). These expressions
|
|
|
|
|
* may themselves contain single or double quoted strings, although the double
|
|
|
|
|
* quoted strings may not contain interpolated expressions.
|
|
|
|
|
*
|
|
|
|
|
* These embedded constructs influence the output and formatting and are an
|
|
|
|
|
* important part of a program and require highlighting.

Some constructs mandate one or the other, but usually the author has may choose

T3_SEENSTART is used to indicate that a braceless TLB has been (potentially)
|
|
|
|
|
seen and is also used to match the closing ';' of the default style.
|
|
|
|
|
|
|
|
|
|
T3_EXPECTINGIDENTIFIER and T3_EXPECTINGPUNCTUATION are used to keep track of
|
|
|
|
|
what characters may be seen without incrementing the block level. The general
|
|
|
|
|
pattern is identifier <punc> identifier, acceptable punctuation characters
|
|
|
|
|
are ':', ',', '(' and ')'. No attempt is made to ensure that punctuation
|
|
|
|
|
characters are syntactically correct, eg parentheses match. A ')' always
|
|
|
|
|
signifies the start of a block. We just need to check if it is followed by a
|
|
|
|
|
'{', in which case we let the brace handling code handle the folding level.
|
|
|
|
|
|
|
|
|
|
expectingIdentifier == false && expectingIdentifier == false
|
|
|
|
|
Before the start of a TLB.
|
|
|
|
|
|
|
|
|
|
expectingIdentifier == true && expectingIdentifier == true
|
|
|
|
|
Currently in an identifier. Will accept identifier or punctuation.
|
|
|
|
|
|
|
|
|
|
expectingIdentifier == true && expectingIdentifier == false
|
|
|
|
|
Just seen a punctuation character & now waiting for an identifier to start.
|
|
|
|
|
|
|
|
|
|
expectingIdentifier == false && expectingIdentifier == truee
|
|
|
|
|
We were in an identifier and have seen space. Now waiting to see a punctuation
|
|
|
|
|
character
|
|
|
|
|
|
|
|
|
|
Space, comments & preprocessor directives are always acceptable and are
|
|
|
|
|
equivalent.
