# Module Creation Guide

## Style Reference

When creating new modules, you MUST match the visual style of the existing project. Follow these steps IN ORDER:

### Step 1: Check for `docs/project-styles.md`
- If the file exists → read it and use it as your style reference. DONE — skip to module creation.
- If the file does NOT exist → continue to Step 2.

### Step 2: Determine if exploration is needed
- Count modules in `template/estandar/modulos/` that have `builder.json` and do NOT start with `custom-`
- If 3+ qualifying modules exist → continue to Step 3
- If fewer than 3 → skip exploration, create the module based on the user's description. The style will be defined as modules are created.

### Step 3: Explore and GENERATE the style guide (MANDATORY)
- Read `index-base.tpl` and `style.css` of 3-4 representative modules (only those with `builder.json`, skip `custom-*`)
- **You MUST then call `save_project_styles`** with a markdown summary including:
  - Primary/secondary/accent colors (hex values)
  - Font families and sizes used
  - Spacing scale (padding/margin patterns)
  - Common Tailwind classes and custom CSS patterns
  - Button styles, card styles, section layouts
  - Any recurring design patterns (gradients, shadows, borders, etc.)
- This saves `docs/project-styles.md` which will be read by future module creation tasks — no re-exploration needed.

**After creating a module:** if `docs/project-styles.md` does not exist yet and there are now 3+ modules, call `save_project_styles`.

## Module Structure

Each module lives in `template/estandar/modulos/<moduleId>/` with:
- `index-base.tpl` — Twig template (source — EDIT THIS)
- `style.css` — Module styles
- `script.js` — Module JavaScript
- `builder.json` — Compiled builder vars (auto-generated, do NOT edit)
- `index.tpl` / `index-twig.tpl` — Compiled (auto-generated, do NOT edit)

## Creating a Module — Full Workflow

1. **Read style reference** (steps above)
2. **`acai-write`** — Create the module files directly (`index-base.tpl`, `style.css`, `script.js`, optional `hook.php`) using project-relative paths and complete file contents.
3. **Automatic compile** — Writing `index-base.tpl` automatically creates the generated template placeholders and triggers compilation. Only use `compile_module` manually if you need to re-run compilation without changing the file.
4. **`add_module_to_record`** — Adds the module to a page. Response includes `sectionId` — use it directly in the next step.
5. **`set_module_config_vars`** — Fill variables with content. Response includes `uploadFields` with `{ fieldName, recordNum }` for each upload variable.
6. **Upload images** — Use `generate_image` then `upload_record_image` with the `recordNum` and `fieldName` from step 5's `uploadFields`. No need to read builder.json or call get_module_config_vars.
7. **`navigate_browser`** — Navigate to the page so the user can see the result.

## HTML Field Types

Use these `data-field-type` attributes in `index-base.tpl`:

| Attribute | Purpose | Example |
|-----------|---------|---------|
| `headfield` | Editable heading | `<h2 data-field-type="headfield">Title</h2>` |
| `textfield` | Short editable text | `<span data-field-type="textfield">Text</span>` |
| `wysiwyg` | Rich text editor | `<div data-field-type="wysiwyg">Content</div>` |
| `upload` | Image upload | `<img data-field-type="upload" src="...">` |
| `list` | Select dropdown | `<div data-field-type="list" data-options="opt1,opt2">` |
| `multiv2` | Repeater/records | `<div data-field-type="multiv2">...</div>` |
| `checkbox` | Toggle | `<div data-field-type="checkbox">` |
| `colorpicker` | Color picker | `<div data-field-type="colorpicker">` |

## MJML Modules

Modules with `MJMLModule: true` in their schema are email modules:
- Only appear when the page table is `mail_marketing`
- For `mail_marketing` tables, only MJML modules are shown
- Use MJML markup instead of standard HTML

## Key Rules

- Always use Tailwind CSS as primary styling
- Use `section_id` variable for unique anchors/scoping
- Use `interno` variable to detect CMS editor vs public view
- Include other modules with: `<module_id :param1="value1"></module_id>`
- Editing `index-base.tpl` with `acai-write` or `acai-line-replace` compiles automatically
- Twig uses filters (with `|`), never functions
- Twig concatenation uses `~`: `'value=' ~ variable`
