metalsmith-layouts
A metalsmith plugin for layouts
This plugin allows you to apply layouts to your source files. It passes your source files to the selected layout as the variable contents
and renders the result with the templating engine of your choice. You can use any templating engine supported by consolidate.js.
For support questions please use stack overflow or our slack channel. For templating engine specific questions try the aforementioned channels, as well as the documentation for consolidate.js and your templating engine of choice.
Installation
$ npm install metalsmith-layouts
Example
Configuration in metalsmith.json
:
{
"plugins": {
"metalsmith-layouts": {
"engine": "handlebars"
}
}
}
Source file src/index.html
:
---
layout: layout.html
title: The title
---
<p>The contents</p>
Layout layouts/layout.html
:
<!doctype html>
<html>
<head>
<title>{{title}}</title>
</head>
<body>
{{{contents}}}
</body>
</html>
Results in build/index.html
:
<!doctype html>
<html>
<head>
<title>The title</title>
</head>
<body>
<p>The contents</p>
</body>
</html>
This is a very basic example. For more elaborate examples see the metalsmith tag on stack overflow.
Options
You can pass options to metalsmith-layouts
with the Javascript API or CLI. The options are:
- engine: templating engine (required)
- default: default template (optional)
- directory: directory for the layouts, layouts by default (optional)
- partials: directory for the partials (optional)
- pattern: only files that match this pattern will be processed (optional)
- rename: change the file extension of processed files to
.html
(optional)
engine
The engine that will render your layouts. Metalsmith-layouts uses consolidate.js to render templating syntax, so any engine supported by consolidate.js can be used. Don't forget to install the templating engine separately. So this metalsmith.json
:
{
"plugins": {
"metalsmith-layouts": {
"engine": "swig"
}
}
}
Will render your layouts with swig.
default
The default layout to use. Can be overridden with the layout
key in each file's YAML frontmatter, by passing either a layout or false
. Passing false
will skip the file entirely.
If a default
layout has been specified, metalsmith-layouts
will process all files unless a pattern has been passed. Don't forget to specify the default template's file extension. So this metalsmith.json
:
{
"plugins": {
"metalsmith-layouts": {
"engine": "swig",
"default": "default.html"
}
}
}
Will apply the default.html
layout to all files, unless overridden in the frontmatter.
directory
The directory where metalsmith-layouts
looks for the layouts. By default this is layouts
. So this metalsmith.json
:
{
"plugins": {
"metalsmith-layouts": {
"engine": "swig",
"directory": "templates"
}
}
}
Will look for layouts in the templates
directory, instead of in layouts
.
partials
The directory where metalsmith-layouts
looks for partials. Each partial is named by removing the file extension from its path (relative to the partials directory), so make sure to avoid duplicates. So this metalsmith.json
:
{
"plugins": {
"metalsmith-layouts": {
"engine": "handlebars",
"partials": "partials"
}
}
}
Would mean that a partial at partials/nav.html
can be used in layouts as {{> nav }}
, and partials/nested/footer.html
can be used as {{> nested/footer }}
. Note that passing anything but a string to the partials
option will pass the option on to consolidate.
Make sure to check consolidate.js and your templating engine's documentation for guidelines on how to use partials.
pattern
Only files that match this pattern will be processed. So this metalsmith.json
:
{
"plugins": {
"metalsmith-layouts": {
"engine": "handlebars",
"pattern": "**/*.hbs"
}
}
}
Would process all files that have the .hbs
extension. Beware that the extensions might be changed by other plugins in the build chain, preventing the pattern from matching.
We use multimatch for the pattern matching.
rename
Change the file extension of processed files to .html
(optional). This option is set to false
by default. So for example this metalsmith.json
:
{
"plugins": {
"metalsmith-layouts": {
"engine": "handlebars",
"rename": true
}
}
}
Would rename the extensions of all processed files to .html
.
exposeConsolidate
Not available over the metalsmith.json
file.
Exposes Consolidate.requires as a function.
.use(layout('swig', {
exposeConsolidate: function(requires) {
}
}))
Consolidate
Any unrecognised options will be passed on to consolidate.js. You can use this, for example, to disable caching by passing cache: false
. See the consolidate.js documentation for all options supported by consolidate.
Origins
This plugin is a fork of the now deprecated metalsmith-templates. Splitting up metalsmith-templates
into two plugins was suggested by Ian Storm Taylor. The results are:
