nyno-file-write-multiple

Use Mistral AI or JSON to write to Multiple files. The nyno-file-write-multiple workflow step is especially useful if you want to create knowledge bases or quickly start new projects.

Example Workflow:

nyno: '7.0'
workflow:
  - id: '3'
    next: [6]
    step: nyno-file-read
    args: [/input/prompts/output-json-files.md]
    context: {set_context: prev_file}
    label: read /input/prompts/output-json-files.md
  - id: '6'
    next: [4]
    step: gui-input-textarea
    label: ' Send Message (this opens a popup before the workflow)'
  - id: '4'
    next: [5]
    step: ai-mistral-text
    args: ['${prev_file}: ${prev}']
    label: Generate Text with Mistral AI
  - id: '5'
    step: nyno-file-write-multiple
    args: ['${prev}']
    context: {output_dir: /output/proj1}
    label: nyno-file-write-multiple

nyno-file-write-multiple — Write multiple files from an object structure

Description

- step: nyno-file-write-multiple
  args:
    - relative/path1.txt: "File content 1"
      relative/path2.js: "File content 2"

The nyno-file-write-multiple step writes multiple files at once from an object structure where keys are relative file paths and values are file contents. This is particularly useful for:

• Generating multiple configuration files
• Creating directory structures with content
• Writing multiple output files from a single operation

Usage in a workflow YAML:

workflow:
  - step: nyno-file-write-multiple
    args:
      - config/settings.json: '{"api": "enabled"}'
        scripts/init.sh: "#!/bin/bash\necho 'Initializing...'"

---

Parameters

Parameter	Type	Description
context.output_dir	string	Base directory where files will be written (default: /output).
context.set_context	string	Context variable name to store results (default: prev).

---

Return Values

On success (return code 0), stores an object in the specified context variable (default ${prev}):

{
  "success": true,
  "baseDir": "/output",
  "writtenFiles": [
    "/output/relative/path1.txt",
    "/output/relative/path2.js"
  ]
}

On failure (return code -1), stores error information in ${prev_error} (or ${[set_context]_error}):

{
  "errorMessage": "Error description"
}

---

Behavior

• Creates parent directories automatically if they don't exist
• Skips files with paths attempting to escape the output directory (paths starting with ..)
• Converts all content to strings (objects will be [object Object] unless stringified first)
• Overwrites existing files without warning
• Normalizes path separators across operating systems

---

Context Options

Option	Type	Default	Description
output_dir	string	/output	Base directory for all file operations
set_context	string	prev	Context variable name for results

---

Examples

Example #1 — Basic usage with inline object

workflow:
  - step: nyno-file-write-multiple
    args:
      - README.md: "# Project\n\nInitial setup"
        config.json: '{"version": 1}'

Example #2 — Using previous step output

workflow:
  - step: some-data-generator
    context:
      set_context: file_data
  - step: nyno-file-write-multiple
    args:
      - '${file_data}'
    context:
      output_dir: /custom/output
      set_context: written_files

Example #3 — Creating directory structure

workflow:
  - step: nyno-file-write-multiple
    args:
      - src/index.js: "console.log('Hello')"
        src/utils/helper.js: "export function help() {}"
        package.json: '{"name": "my-project"}'

Example #4 — Using with template variables

workflow:
  - step: nyno-uuidv4
    context:
      set_context: unique_id
  - step: nyno-file-write-multiple
    args:
      - temp/${unique_id}/data.txt: "Temporary data"
        temp/${unique_id}/meta.json: '{"id": "${unique_id}"}'
