    Template Compile extension for Fepper

    Export fully recursed templates in your backend's template language.

    This extension exports templates from the source/_patterns/03-templates directory to the backend, similar to the way that fp template does. However, the output will compile all included partials. Furthermore, this extension obviates the need to declare a translation for each tag.

    This should prove to be a simpler alternative to Fepper core's fp template task, but it is probably not appropriate for many CMSs (like Drupal and WordPress) for which fp template was originally designed.

    Instead, this extension is more suitable for Express-like applications, where any number of routes can be assigned a unique template for rendering HTML. Unlike Drupal and WordPress, instead of the backend trying to determine which partial goes where, the inclusion of partials, as appropriate per route, would be prototyped in Fepper. Running fp tpl-compile would then compile a single template per route.


    cd extend
    npm install --save-dev fp-tpl-compile


    fp tpl-compile

    This does the compilation as described in the first paragraph. You will still normally need to translate from Fepper's Mustache syntax (Feplet) to the backend's template language. fp tpl-compile leverages normal Feplet rendering, but targets the tag delimiters instead of the entire tag. You are free to use any alternate delimiter, but we recommend ERB notation, as exemplified in the Mustache docs. Wrap them in triple curly braces and use them as opening and closing delimiters. Use these wrapped delimiters to surround tags destined for the backend. In the example of ERB alternate delimiters and regular {{ and }} delimiters for the backend, the .json file specific to the Fepper template must declare <% and %> keys and have their values be {{ and }} respectively. In source/_data/_data.json file, their values should be <!-- and --> so they can be ignored by humans viewing the UI.

    Each template that is to be compiled requires a .json file with alternate and backend delimiter declarations. While this may appear to be unnecessarily repetitive, it leverages normal Fepper rendering, instead of hacking around it. It also avoids the chaos that global configurations for opening and closing delimiters for alternate and backend tags would instill. (Yes, that's four configurations. Yes, their keys would be long and/or unguessable.)

    The tpl_compile_dir and tpl_compile_ext preferences need to be configured in pref.yml or the template's .yml file. In this way, fp tpl-compile will know where to write, and what extension to use.

    fp tpl-encode:hbs -e .ext

    fp tpl-encode:hbs works in the reverse direction. It encodes backend templates for use as Fepper templates, which can in turn, be compiled back to the backend. Assuming the backend template is fully fleshed out, copy it to source/patterns/03-templates. Do not change its name. Then, run the command with the extension used by the backend. The copied backend template in source/patterns/03-templates will be replaced by a .mustache file, accompanied by a .json file.

    The .json file will declare ERB notation for alternate delimiters. The encoder will also add the "<%": "<!--" and "%>": "-->" key:value pairs to source/_data/_data.json if they aren't there already.

    One gotcha to be aware of is that underscore-prefixed hidden files must not have a corresponding .json file. Underscore-prefixed .json files will get compiled into source/_data/data.json, possibly overwriting values for <% and %>.

    fp tpl-encode:hbs encodes any backend language with tags delimited by {{ and }}.

    The output HTML will be formatted by js-beautify. To override the default configurations, modify the .jsbeautifyrc file at the root of Fepper.

    source/_patterns/03-templates/example.yml (or append to pref.yml):

      "placeholder_content": "Lorem ipsum",
    Insert into source/_data/_data.json:
    "<%": "<!--",

    Compiles to backend/docroot/templates/example.hbs:
