Function expandTracedToNodeIf

Convenience function for creating a CompositeGeneratorNode being configured with the provided tracing information in form of {astNode, property?, index: undefined} and appending content in form of a template, if condition is equal to true.

If condition is satisfied, this function returns a tag function that takes the desired template and does the processing by delegating to expandToNode and traceToNode and finally returning the resulting generator node. Otherwise, the returned function just returns undefined.

Example

expandTracedToNodeIf(entity !== undefined, entity)`
      Hello ${ traceToNode(entity, 'name')(entity.name) }
  `.appendNewLine()

If condition is satisfied, this function returns a tag function that takes the desired template and does the processing by delegating to expandToNode and traceToNode and finally returning the resulting generator node. Otherwise, the returned function just returns undefined.

Example

expandTracedToNodeIf(entity !== undefined, entity, 'definitions', 0)`

Convenience function for creating a CompositeGeneratorNode being configured with the provided tracing information in form of concrete coordinates and appending content in form of a template, if condition is equal to true. Complete coordinates are provided by the AstNodes' corresponding AstNode.$cstNodes.

This function returns a tag function that takes the desired template and does the processing by delegating to expandToNode and traceToNode and finally returning the resulting generator node.

If sourceRegion is a function supplying the corresponding region, it's only called if condition is satisfied.

Example

expandTracedToNodeIf(entity !== undefined, entity.$cstNode)`
      Hello ${ traceToNode(entity, 'name')(entity.name) }
  `.appendNewLine()

Convenience function for creating a CompositeGeneratorNode being configured with the provided tracing information in form of a list of concrete coordinates and appending content in form of a template, if condition is equal to true. Complete coordinates are provided by the AstNodes' corresponding AstNode.$cstNodes.

This function returns a tag function that takes the desired template and does the processing by delegating to expandToNode and traceToNode and finally returning the resulting generator node.

The list of regions in sourceRegions will later be reduced to the smallest encompassing region of all the contained source regions. If sourceRegions is a function supplying the corresponding regions, it's only called if condition is satisfied.

Example

expandTracedToNodeIf(entity !== undefined, [
     findNodeForKeyword(entity.$cstNode, '{')!,
     findNodeForKeyword(entity.$cstNode, '}')!
  ])`
      Hello ${ traceToNode(entity, 'name')(entity.name) }
  `.appendNewLine()
