# Custom ComfyUI Nodes Languages: **English** · [Русский](README_RU.MD) This repository contains custom nodes for ComfyUI that extend functionality for workflows. ## Available Nodes ### Text Processing Nodes #### 1. Variable builder [darkilNodes] ![Variable builder](docs/images/node_var_build.png) - **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] ![Advanced variable builder](docs/images/node_adv_var_build.png) - **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 - `float_format` (STRING): Format string for floats #### 3. Dynamic prompt builder [darkilNodes] ![Dynamic prompt builder 1](docs/images/node_prompt_build_1.png) ![Dynamic prompt builder 2](docs/images/node_prompt_build_2.png) - **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) #### 4.
