Runtime Semantics: CompileAtom
|
|
The syntax-directed operation CompileAtom takes arguments direction (forward or backward) and modifiers (a Modifiers Record) and returns a Matcher.
|
|
|
|
Atom :: `(` `?` RegularExpressionFlags `:` Disjunction `)`
|
|
1. Let addModifiers be the source text matched by RegularExpressionFlags.
|
|
2. Let removeModifiers be the empty String.
|
|
3. Let newModifiers be UpdateModifiers(modifiers, CodePointsToString(addModifiers), removeModifiers).
|
|
4. Return CompileSubpattern of Disjunction with arguments direction and newModifiers.
|
|
|
|
UpdateModifiers ( modifiers, add, remove )
|
|
The abstract operation UpdateModifiers takes arguments modifiers (a Modifiers Record), add (a String), and remove (a String) and returns a Modifiers. It performs the following steps when called:
|
|
|
|
1. Let dotAll be modifiers.[[DotAll]].
|
|
2. Let ignoreCase be modifiers.[[IgnoreCase]].
|
|
3. Let multiline be modifiers.[[Multiline]].
|
|
4. If add contains "s", set dotAll to true.
|
|
5. If add contains "i", set ignoreCase to true.
|
|
6. If add contains "m", set multiline to true.
|
|
7. If remove contains "s", set dotAll to false.
|
|
8. If remove contains "i", set ignoreCase to false.
|
|
9. If remove contains "m", set multiline to false.
|
|
10. Return the Modifiers Record { [[DotAll]]: dotAll, [[IgnoreCase]]: ignoreCase, [[Multiline]]: multiline }.
