THIS API IS CURRENTLY COMPLETELY "WORK IN PROGRESS" AND SUBJECT TO DAILY CHANGES!!

THE SAMPLE CODE IS USED TO RESEARCH THE API AND WILL BE COMPLETELY REWRITTEN SOON

A SimpleExpressions is build by chaining commands one after the other. Two consecutive members are separated by a ..

Basic construct

Two Content members chained one after the other imply "the first one - then - the second one" ; they thus are to be chained with the Then keyword:

Text("http").Then.Text("://") //means that we want to match "http://"
Text("http").Then.Maybe("s").Then.Text("://") //means we want to match "http://" and "https://"

The functions

Here are all the functions that SimpleExpressions currently supports:

Content

• Alphanumerics, Letters, Numbers
• One(char/string), OneOf(string)
• Text(string)
• Maybe
• Anything
• EitherOf(string)

Modifiers

• InRange(string)
• Except(string)

Logical operators

• Then
• Either.X.Or.Y.Then

Qualifiers

• PreRepeaters OneOrMore, ZeroOrMore
• PostRepeaters AtLeast, AtMost, Exactly

Bounds

• Repetitions
• Single-element repetition Exactly(int)/AtLeast(int).AtMost(int)
• Multi-element repetition Repeat.X.Exactly(int)/AtLeast(int).AtMost(int).Times
• Groups Group.X.Y.Together.As(string)

Functions and ideas - HERE BE BIG DRAGONS!

Work in Progress

• -AndWhitespaces
• Word(string)
• StartsWith
• EndOfLine
• Maybe

Ideas

• CaseInsensitive
• EndOfWord
• AsWord
• AsLine
• Greedy

Perform structural checks (dogfed with SimpleExpressions :D ). Due to the dynamic nature of SimpleExpressions, such a check can only happen after the parsing of the tokens has been done.

• Group + Together/As/Together-As
• AtLeast/Exactly/AtLeast-AtMost
• Repeat + AtLeast/AtLeast-AtMost/Exactly + Times
• Character(char) <- parameter check 'x'
• InRange(string) <- parameter format x-y

Other

• Simplify generation of parameters using arrays/collections?

After discusion with Miwi, evaluate:

• Sequence -> Text? @?
• Either-Or(-Then)
• Alphanumeric/Letter/Number, no "s"
• ZeroOrMore
• OneOrMore
• Precedence And > Or
