public JavaScriptLinkGenerator(JavaScriptLanguageSupport language)

Method Details

isLinkAtOffset

public org.fife.ui.rsyntaxtextarea.LinkGeneratorResult isLinkAtOffset(org.fife.ui.rsyntaxtextarea.RSyntaxTextArea textArea,
 int offs)

Specified by:

isLinkAtOffset in interface org.fife.ui.rsyntaxtextarea.LinkGenerator

createSelectedRegionResult

protected org.fife.ui.rsyntaxtextarea.LinkGeneratorResult createSelectedRegionResult(org.fife.ui.rsyntaxtextarea.RSyntaxTextArea textArea,
 org.fife.ui.rsyntaxtextarea.Token t,
 JavaScriptDeclaration dec)

Returns:

LinkGeneratorResult based on the JavaScriptDeclaration and the position

setFindLocal

public void setFindLocal(boolean find)

Parameters:

find - flag to state whether to look in the RSTA editing script for variable/function completions

setFindPreprocessed

public void setFindPreprocessed(boolean find)

Parameters:

find - flag to state whether to look in the pre-processed scripts for variable/function completions

setFindSystem

public void setFindSystem(boolean find)

Parameters:

find - flag to state whether to look in the system scripts for variable/function completions

getLookupNameForFunction

private String getLookupNameForFunction(org.fife.ui.rsyntaxtextarea.RSyntaxTextArea textArea,
 int offs,
 String name)

Convert the function Token to JavaScript variable resolver lookup name by replacing any parameters with 'p' and stripping any whitespace between the parameters: e.g. Token may contain the function: addTwoNumbers(num1, num2);

The return result will be: addTwoNumbers(p,p);

Returns:

converted function name to variable resolver lookup name

checkForLinkableToken

private JavaScriptLinkGenerator.IsLinkableCheckResult checkForLinkableToken(org.fife.ui.rsyntaxtextarea.RSyntaxTextArea textArea,
 int offs)

Checks if the token at the specified offset is possibly a "click-able" region.

Parameters:

textArea - The text area.

offs - The offset, presumably at the mouse position.

Returns:

A result object.

wrapToken

private org.fife.ui.rsyntaxtextarea.Token wrapToken(org.fife.ui.rsyntaxtextarea.Token token)

Due to the Tokens being reused, this can cause problems when finding the next token associated with a token. Wrap the tokens to stop this problem.

Parameters:

token - to wrap

Returns:

copy of the original token

getLanguage

public JavaScriptLanguageSupport getLanguage()

Returns:

JavaScriptLanguage support
