installSyntaxPack

public boolean installSyntaxPack(java.net.URL syntaxPack)

Install all built-in Syntaxes from a syntax Pack.

Distributing a syntax pack

Syntax packs are jar files which contains classes which extends the TokenMarker class. Two additional properties files must be present in the jar file:

• A properties files which maps file extensions to syntax names
• A properties files which maps syntax names to the associated class path of the syntax

The Manifest of the jar file must contain two properties:

• MANIFEST_EXTENSIONS: the path of the file for the <extensions>-<syntax names> properties
• MANIFEST_TYPES: the path of the file for the <syntax names>-<TokenMarker class path> properties

Parameters:

syntaxPack - the syntax pack

Returns:

true if the install was successful

Distributing a syntax pack

Syntax packs are jar files which contains classes which extends the TokenMarker class. Two additional properties files must be present in the jar file:

• A properties files which maps syntax names to the associated class path of the syntax

The Manifest of the jar file must contain two properties:

• MANIFEST_EXTENSIONS: the path of the file for the <extensions>-<syntax names> properties
• MANIFEST_TYPES: the path of the file for the <syntax names>-<TokenMarker class path> properties

Parameters:

syntaxPack - the syntax pack
