Available Nodes

Text Processing Nodes

1. Variable builder [darkilNodes]

• Category: darkilNodes/text
• Description: Builds text variables from multiple inputs with configurable formatting.
• Features:
  • Supports multiple input types (text, integers, floats)
  • Configurable separators and prefixes/suffixes
  • Conditional output based on input presence
• Inputs:
  • switch (BOOL): node active toggle
  • out_val_by_switch (BOOL): return if active
  • var_name (STRING): variable name
  • var_value (STRING): variable value
  • INPUT_VAR (STRING): other variables input

2. Advanced variable builder [darkilNodes]

• Category: darkilNodes/text
• Description: Advanced text variable builder with complex formatting options.
• Features:
  • Supports multiple input types with custom formatting
  • Configurable separators and prefixes/suffixes
  • Conditional output based on input presence
  • Customizable number formatting for integers and floats
• Inputs:
  • switch (BOOL): node active toggle
  • out_val_by_switch (BOOL): return if active
  • var_name (STRING): variable name
  • var_text (STRING): variable value
  • INPUT_VAR (STRING): other variables input
  • DYNAMIC_* (STRING): dynamic inputs
  • condition (BOOLEAN): When True, outputs only if inputs are present
  • int_format (STRING): Format string for integers

3. Dynamic prompt builder [darkilNodes]

• Category: darkilNodes/text
• Description: Builds prompts from a small template language. Placeholders and toggle tags written in the prompt text spawn matching widgets on the node, so one prompt can be reconfigured live without editing the text.
• Features:
  • Placeholders {{NAME:TYPE:VALUE:DEFAULT:USE_INPUT}} create dynamic widgets. TYPE = STRING, INT, FLOAT, COMBO, SLIDER, KNOB; USE_INPUT (true) exposes an input socket for the value.
  • Toggle tags [[TAG]]…[[/TAG]] keep or drop the wrapped block via a per-tag switch. [[TAG:GROUP]] makes tags sharing a GROUP mutually exclusive (radio behavior). Tags can be nested.
  • Extra block [%extra%]…[%/extra%] is compiled to a second output; Vars block [%vars%]…[%/vars%] is ignored by the backend (a notes/scratch area).
  • Comments removed before processing: // …, # …, /* … */.
  • Spaceless blocks {%spaceless%}…{%spaceless stop%} collapse whitespace, and formatting directives (lower, upper, title, sentence, trim, dedent, list, list_and, …) transform the wrapped text and can be nested.
  • Syntax-highlighting editor: color highlighting, an Insert / Vars menu, caret-context hints, validation underlines, and keyboard autocomplete (EN/RU localized).
  • Compact switch bar: three inline switches on one row — EDITOR (show/hide the editor), PROMPT (process the main prompt), EXTRA (process the extra block).
• Inputs:
  • prompt (STRING, multiline): the prompt template with placeholders, tags, blocks and directives
• UI switches (client-side, one compact row):
  • EDITOR: show/hide the prompt editor widget
  • PROMPT: enable/disable processing of the main prompt (compiled_prompt)
  • EXTRA: enable/disable processing of the extra block (extra_compiled)
• Outputs:
  • compiled_prompt (STRING): the processed main prompt (empty when PROMPT is off)
  • extra_compiled (STRING): the processed extra block (empty when absent or EXTRA is off)
