nl_tokens: / * Some bundlers ( SystemJS builder ) sometimes want to rename dependencies . Here we check if alternative name was provided for a given moduleName and return it if possible .
pl_tokens: function tryRenameExternalModule ( moduleName ) { if ( currentSourceFile . renamedDependencies && <mask> . hasProperty ( currentSourceFile . renamedDependencies , moduleName . text ) ) { return "\"" + currentSourceFile . renamedDependencies [ moduleName . text ] + "\"" ; } return undefined ; }
