Hyva Tailwind Include Exclude

Add Module to Tailwind Include or Exclude List

Adds a module path as a { "src": "<PATH>" } entry to either the tailwind.include or tailwind.exclude array in a theme's hyva.config.json. This is the Hyvä 1.4+ / Tailwind v4 mechanism; Step 3 handles older setups.

Skill deps (read via <skill_path>/../{name}/SKILL.md): hyva-theme-list, hyva-compile-tailwind-css

Step 1: Determine the Target List

Decide whether the user wants to include or exclude the module in Tailwind CSS compilation:

• If the user's request clearly indicates one (e.g. "exclude", "include"), use it.
• Otherwise, ask the user whether to include or exclude the module. Wait for the answer before proceeding.

The chosen list is referred to as <target> (include or exclude) in the steps below.

Step 2: Find the Theme(s)

Use the hyva-theme-list skill to find all Hyvä themes. For each theme, the config file is located at <theme-path>/web/tailwind/hyva.config.json.

• If no themes are found, inform the user and stop.
• If only one theme is found, use it directly.
• If multiple themes are found, list them and ask the user which theme(s) to update. Wait for the answer before proceeding.
• If a selected theme is located under vendor/, warn the user that changes to vendor files are lost on composer update and ask for confirmation before proceeding.

Step 3: Confirm the Theme Uses Tailwind v4

hyva.config.json is only read by Hyvä 1.4+ / Tailwind v4 builds (via hyva-sources). Editing it on an older setup is a silent no-op. For each selected theme, read the tailwindcss version in <theme-path>/web/tailwind/package.json.

• If the major version is 4 or higher, continue to Step 4.
• If the major version is 3, the build does not read hyva.config.json; do not create or edit it. Instead tell the user how to make the change in the v3 setup, then stop for that theme:
  • To exclude a module, add its directory to excludeDirs in the postcssImportHyvaModules(...) call in <theme-path>/web/tailwind/postcss.config.js.
  • To include extra paths, add them to the content array in <theme-path>/web/tailwind/tailwind.config.js.

Step 4: Resolve the Module Path

Use the current working directory as the project root. If a module name was provided by the user when invoking the skill, use it. Otherwise, prompt the user for the module to resolve.

For an exclude

The exclude path must match the module's registered source path, which the build reads from app/etc/hyva-themes.json (a module can only be excluded if it is registered there).

• Read app/etc/hyva-themes.json and find the entry for the module, matching by its Vendor_Module name or by the provided path or directory name.
• Use that entry's registered source path verbatim. It often ends in /src (e.g. vendor/hyva-themes/magento2-hyva-checkout/src).
• If the module is not listed there, it is not imported by the build and cannot be excluded. Inform the user and stop.

For an include

Any directory relative to the project root can be included, so resolve it from the provided value:

• If the value contains / (e.g. vendor/vendor-name/module-name), verify the directory exists relative to the project root and use it as-is. If it does not exist, warn the user and ask how to proceed.
• If the value is a Vendor_Module name (e.g. Hyva_Checkout), look for app/code/<Vendor>/<Module> relative to the project root and use that path if it exists. If it is not found there, look it up under vendor/ via its registration.php.
• Otherwise (a plain directory name, e.g. magento2-hyva-checkout), search for a directory matching the name under vendor/ and app/code/:
  • If no match is found, inform the user and stop.
  • If exactly one match is found, derive its relative path from the project root (e.g. vendor/hyva-themes/magento2-hyva-checkout).
  • If multiple matches are found, list them and ask the user which one to use. Wait for the answer before proceeding.

Step 5: Update Each Target File

For each target hyva.config.json:

1. Read the file. If it does not exist, create it with the structure { "tailwind": { "<target>": [] } }. If the file exists but is not valid JSON, inform the user and stop without overwriting it.
2. Check if an entry with the resolved path already exists in tailwind.<target>. If it does, inform the user and skip that file. If the path exists in the opposite list (tailwind.exclude when including, or tailwind.include when excluding), warn the user and ask whether to remove it from there.
3. Add { "src": "<PATH>" } to the tailwind.<target> array, where <PATH> is the resolved module path from Step 4. Create the tailwind key and the <target> array if they are missing. For example, excluding a module results in:

   {
     "tailwind": {
       "exclude": [
         { "src": "vendor/hyva-themes/magento2-hyva-checkout/src" }
       ]
     }
   }
   

4. Write the updated JSON back, preserving the file's existing indentation and trailing newline.

Step 6: Confirm

Report which file(s) were updated, which list (include or exclude) was changed, and what path was added.

Step 7: Offer to Compile

The change has no visible effect until Tailwind CSS is recompiled. Offer to compile the Tailwind CSS for the updated theme(s) using the hyva-compile-tailwind-css skill so the change takes effect.
