From 93d60933651ccc2bad30abf817b445cadf9ac6da Mon Sep 17 00:00:00 2001 From: Nicolas Molina Monroy Date: Tue, 13 Oct 2026 07:10:06 -0400 Subject: [PATCH 1/7] Add the dot-ui-vtl-migration skill, driven by the dotCMS MCP Port the skill from dotCMS/core. The single-file migration rules and guide are copied unchanged. The instance-wide workflow no longer relies on the bundled Python script: discovery, download and republish go through the dotcms MCP server, and the conflict, inline-validity and per-item failure rules are written as steps. Registers the skill in the marketplace and README.

Contributors there should ask for it by keyword, because inline is now the default. + +**Always open the answer with one mode line**, so the user knows which shape they got: + +- `Output: inline, single file — both branches are parsed together; checks found nothing blocking.` +- `Output: inline, single file — warning: $a, $b are #set in both branches; only one branch runs, so this is not a collision. Three files is the alternative.` +- `Output: three files with router (_old.vtl, _new.vtl, .vtl).` +- `Output: none — inline blocked: . . Three files avoids it. Reply "inline anyway" to force it, or "three files".` + +### Mode 1 — Inline (default) + +One file. The migrated code goes in the `#if`, the original code in the `#else`: + +```vtl +#if( $structures.isNewEditModeEnabled() ) + +#else + +#end +``` + +Rules. Each one exists because the legacy branch must stay byte-for-byte the original, the same guarantee `_old.vtl` gives: + +- **The header is exactly** `#if( $structures.isNewEditModeEnabled() )`. `#else` and `#end` are each on their own line. +- **Do not indent either branch** to sit inside the `#if`. Both start at column 0. Indenting changes every legacy line. +- **The `#else` branch is the original, verbatim.** Do not reformat it, translate its comments, fix its typos, remove its trailing spaces or change its line endings. If it has a bug, leave it; mention it in your answer if it matters. +- **Never add a `#parse`** and never write `_new`/`_old` files in this mode. +- **Never ask for a filename or server path.** The user may have only the field's content, pasted from the content type editor; inline needs no path. If a path *was* given, the single file keeps the original file's name and replaces it. +- **Run the checks in "Before emitting inline" first.** They can stop the output. + +**When the original is a file on disk** (you were given a path), do not retype it. Write the migrated version to a temporary file, then assemble with the shell so the legacy bytes are copied, not regenerated. This is the only reliable way to keep CRLF line endings and a missing final newline: + +```sh +{ printf '#if( $structures.isNewEditModeEnabled() )\n'; cat migrated.vtl; printf '\n#else\n'; cat original.vtl; printf '\n#end'; } > result.vtl +``` + +When the content was pasted, copy the pasted legacy code into the `#else` exactly as the user sent it. + +### Before emitting inline + +Velocity parses the **whole file** before it renders either branch. With the router, the branch not taken is never even parsed; inline, both are. So some problems that only affected the legacy editor in the three-file shape would break the new editor too. Before emitting inline, read both branches and check: + +| Finding | Severity | What to do | +|---|---|---| +| A `#macro` with the same name in both branches | **Blocking** | Macros are registered at parse time, and the first definition wins. That is the migrated one, so the legacy editor would silently run the new macro. Emit nothing; name the macro; offer three files. | +| The legacy branch would not parse on its own: a `#if`/`#foreach`/`#macro`/`#define` without its `#end`, a stray `#end`, an `#else` outside an `#if` | **Blocking** | Inline would carry that parse error into the new edit mode. Emit nothing; give the line; offer three files. | +| The migrated branch would not parse on its own | **Blocking** | If you migrated it, that is a bug in your migration: fix it before emitting anything. If it came from the user (collapse or split), report the line like the legacy case and write nothing. | +| The same variable `#set` in both branches | Warning | `#set` runs at render time and only one branch renders, so this is not a collision. Emit, but list the names in the mode line. | + +Count directives the way Velocity does. Text inside `##`, `#* *#` and `#[[ ]]#` is not code, and `\#end` is escaped. A directive name also ends at the first character that is not a letter, digit, `_` or `@`, so `$('#end-date')` in a script **is** an `#end`, while `#endDate` is not. The full rules and examples are in `reference/migration-guide.md` → "Output Modes". + +After a blocking finding, emit inline only if the user explicitly insists ("inline anyway"), and restate the finding in the mode line when you do. + +### Mode 2 — Three files with a router + +Use this mode when the request asks for it (see the table above). Given an original file at `/static/personas/keytag_custom_field.vtl`, the three outputs are: + +--- + +#### File 1 — `keytag_custom_field_old.vtl` +The **original file content, completely unchanged**. Copy it verbatim — every deprecated API call, every dijit class, every dojo.ready. This is the fallback for the legacy editor. + +--- + +#### File 2 — `keytag_custom_field_new.vtl` +The **fully migrated file** with all deprecated patterns replaced per the migration rules. + +--- + +#### File 3 — `keytag_custom_field.vtl` (replaces the original) +The **conditional router** — this file takes the name of the original and delegates to `_new` or `_old` based on which edit mode is active: + +```vtl +#if( $structures.isNewEditModeEnabled() ) + #parse('/static/personas/keytag_custom_field_new.vtl') +#else + #parse('/static/personas/keytag_custom_field_old.vtl') +#end +``` + +The `#parse` paths must use the **full server path** of the file, not just the filename. Use the same directory as the original file. Indent the `#parse` lines with a tab and end the file right after `#end`, with no final newline, as the routers already in the repository do. On disk, write it with `printf` so no newline is added. + +--- + +This pattern lets both legacy and new edit modes coexist safely — old editor users continue using the deprecated code, new editor users get the modernized version. + +**When the user gives you a file path**, derive all three filenames automatically. In three-file mode only, if you receive file contents without a path, ask for the filename and its server path before outputting, because `#parse` cannot work without it. + +### Converting between modes + +Conversion only moves content. **Never apply a migration rule to either branch while converting.** It is a re-shaping, not a re-migration. + +**Collapse (router + `_new` + `_old` → one inline file).** Read the router's two `#parse` paths and find the `_new` and `_old` files. The `_new` content goes in the `#if` and the `_old` content in the `#else`, using the Mode 1 layout. Run "Before emitting inline" first; the same findings apply. If the router's paths do not match the files you were given (different names or directories), say so and stop. Do not guess. + +**Split (one inline file → router + `_new` + `_old`).** You need the router's full server path; ask for it if you do not have it. + +1. Find where the branches end. Line 1 is the header. The legacy branch starts after the **top-level** `#else`: the first `#else` line reached while no block opened after line 1 is still open. Count block openers (`#if`, `#foreach`, `#macro`, `#define`, `#literal`, `#@name`) and `#end`s from line 2 on. **Never just take the first `#else`**, because branches often contain their own `#if … #else … #end`. The file ends with the matching `#end`. +2. `_new.vtl` is everything between the header and the top-level `#else`. `_old.vtl` is everything between that `#else` and the final `#end`. In both cases, drop the one newline the inline layout added before the `#else` and before the `#end`. +3. Write the router in Mode 2's shape: tab-indented `#parse` lines with full server paths. + +If the file does not start with `#if( $structures.isNewEditModeEnabled() )`, or has no top-level `#else`, it is not an inline migration. Say so; do not guess. + +**On disk, use the shell for both directions** so bytes are copied, never retyped. Collapse is the Mode 1 command, with `_new` in place of `migrated.vtl` and `_old` in place of `original.vtl`. Split takes line ranges, where `E` is the line number of the top-level `#else` and `L` is the line number of the final `#end`: + +```sh +sed -n "2,$((E-1))p" inline.vtl | perl -pe 'chomp if eof' > name_new.vtl +sed -n "$((E+1)),$((L-1))p" inline.vtl | perl -pe 'chomp if eof' > name_old.vtl +``` + +## Non-Negotiables + +- All `getField()` calls must be inside `DotCustomFieldApi.ready()` +- Never use `DotCustomFieldApi.get()` or `DotCustomFieldApi.set()` (the old short forms) +- VTL variables stay exactly as-is +- Business logic stays exactly as-is — only the API calls and styling approach change +- Dijit CSS classes (any `class="dijit*"`) must be removed +- **Styling:** Prefer DaisyUI component classes + Tailwind utilities; keep custom CSS only when the guide says so +- Translate non-English comments to English **in the migrated code only** +- The legacy code (`#else` branch or `_old.vtl`) is never edited, not even its comments or whitespace +- Server-side VTL variables (`$inode`, `$identifier`, `$lang`, `$contentlet`, `$structure`, `$field`) are resolved at render time — do not confuse them with `DotCustomFieldApi` JavaScript APIs + +## Key Patterns to Know + +**Field reference lifecycle:** +```js +DotCustomFieldApi.ready(() => { + // Get once, reuse everywhere + const titleField = DotCustomFieldApi.getField('title'); + const urlField = DotCustomFieldApi.getField('url'); + + // Read + const current = titleField.getValue() || ''; + + // Write + urlField.setValue(slugify(current)); + + // Watch + titleField.onChange((value) => { + urlField.setValue(slugify(value)); + }); +}); +``` + +**Field visibility and state control:** +```js +DotCustomFieldApi.ready(() => { + const mediaField = DotCustomFieldApi.getField('media'); + const mediaFileField = DotCustomFieldApi.getField('mediafile'); + + // Show/hide based on current value + if (mediaField.getValue() === 'upload') { + mediaFileField.show(); + } else { + mediaFileField.hide(); + } + + // React to changes + mediaField.onChange((value) => { + if (value === 'upload') { + mediaFileField.show(); + } else { + mediaFileField.hide(); + } + }); + + // Enable/disable a field + mediaFileField.disable(); // blocks editing, applies disabled styling + mediaFileField.enable(); // restores interactivity +}); +``` + +**Reacting to validation state (required, errors, touched):** +```html + + + +``` + +> Use a self-contained `is-invalid` class with inline ` + + + + +``` + +**Important gotchas:** + +- **Always gate on `state.touched`.** A required + empty field is `invalid: true` from the moment it mounts.
