getQ2Instance

public static Q2 getQ2Instance()

initQ2

public void initQ2()

getName

public java.lang.String getName()

Overrides:

getName in class Scheme

getLexer

public LispReader getLexer(gnu.kawa.io.InPort inp,
                  SourceMessages messages)

Overrides:

getLexer in class Scheme

getCompilationClass

public java.lang.String getCompilationClass()

Overrides:

getCompilationClass in class Scheme

registerEnvironment

public static void registerEnvironment()

The compiler insert calls to this method for applications and applets.

appendBodyValues

public boolean appendBodyValues()

Description copied from class: Scheme

Should the values of body/block be appended as multiple values? Otherwise, just return the result of the final expression.

Overrides:

appendBodyValues in class Scheme

getPrompter

public Procedure getPrompter()

Overrides:

getPrompter in class Language

createReadTable

public ReadTable createReadTable()

Description copied from class: LispLanguage

Create a fresh ReadTable appropriate for this language.

Overrides:

createReadTable in class Scheme

compareIndentation

public static int compareIndentation(int indentation1,
                     int indentation2)

Compare two indentation amounts. An indentation is (numberOfTabs<<16)+numberOfSpaces. A comparison is indeterminate if it depends on tab-width - e.g. the number of tabs in indentation1 is less than indentation2, but it's the reverse when it comes to spaces.

Returns:

Integer.MIN_VALUE if the comparison is indeterminate; otherwise returns the "difference" between the two (where tabs count as 8 spaces).
