StringSubstitute¶
Replace multiple placeholders in a string using a dictionary mapping.
Each key in the substitutions dictionary represents a placeholder string that will be replaced by its corresponding value. This is useful for templating scenarios where text contains various placeholders (e.g., {{subject_id}}, {{session}}) that need to be filled in with data-dependent values.
If a placeholder from the dictionary is not found in the input string, a warning is emitted (unless verbose is set to False). This allows for flexible templates where not all placeholders may be present in every input string.
All replacement values are converted to strings before substitution. Version 1.0.0
Ports/Properties¶
string¶
String to process.
- verbose name: String
- default value: None
- port type: DataPort
- value type: str (can be None)
- data direction: INOUT
substitutions¶
Dictionary mapping placeholder strings to their replacement values. Each key in the dictionary is a placeholder that will be replaced by its corresponding value. Values are converted to strings before substitution.
- verbose name: Substitutions
- default value: {}
- port type: DictPort
- value type: dict (can be None)
verbose¶
Whether to emit warnings when placeholders from the dictionary are not found in the input string.
- verbose name: Verbose
- default value: True
- port type: BoolPort
- value type: bool (can be None)
set_breakpoint¶
Set a breakpoint on this node. If this is enabled, your debugger (if one is attached) will trigger a breakpoint.
- verbose name: Set Breakpoint (Debug Only)
- default value: False
- port type: BoolPort
- value type: bool (can be None)
metadata¶
User-definable meta-data associated with the node. Usually reserved for technical purposes.
