overview: |
Partial tags are used to expand an external template into the current
template.
The tag's content MUST be a non-whitespace character sequence NOT containing
the current closing delimiter.
This tag's content names the partial to inject. Set Delimiter tags MUST NOT
affect the parsing of a partial. The partial MUST be rendered against the
context stack local to the tag. If the named partial cannot be found, the
empty string SHOULD be used instead, as in interpolations.
Partial tags SHOULD be treated as standalone when appropriate. If this tag
is used standalone, any whitespace preceding the tag should treated as
indentation, and prepended to each line of the partial before rendering.
tests:
- name: Basic Behavior
desc: The greater-than operator should expand to the named partial.
data: { }
template: '"{{>text}}"'
partials: { text: 'from partial' }
expected: '"from partial"'
- name: Failed Lookup
desc: The empty string should be used when the named partial is not found.
data: { }
template: '"{{>text}}"'
partials: { }
expected: '""'
- name: Context
desc: The greater-than operator should operate within the current context.
data: { text: 'content' }
template: '"{{>partial}}"'
partials: { partial: '*{{text}}*' }
expected: '"*content*"'
- name: Recursion
desc: The greater-than operator should properly recurse.
data: { content: "X", nodes: [ { content: "Y", nodes: [] } ] }
template: '{{>node}}'
partials: { node: '{{content}}<{{#nodes}}{{>node}}{{/nodes}}>' }
expected: 'X<Y<>>'
# Whitespace Sensitivity
- name: Surrounding Whitespace
desc: The greater-than operator should not alter surrounding whitespace.
data: { }
template: '| {{>partial}} |'
partials: { partial: "\t|\t" }
expected: "| \t|\t |"
- name: Inline Indentation
desc: Whitespace should be left untouched.
data: { data: '|' }
template: " {{data}} {{> partial}}\n"
partials: { partial: ">\n>" }
expected: " | >\n>\n"
- name: Standalone Line Endings
desc: '"\r\n" should be considered a newline for standalone tags.'
data: { }
template: "|\r\n{{>partial}}\r\n|"
partials: { partial: ">" }
expected: "|\r\n>|"
- name: Standalone Without Previous Line
desc: Standalone tags should not require a newline to precede them.
data: { }
template: " {{>partial}}\n>"
partials: { partial: ">\n>"}
expected: " >\n >>"
- name: Standalone Without Newline
desc: Standalone tags should not require a newline to follow them.
data: { }
template: ">\n {{>partial}}"
partials: { partial: ">\n>" }
expected: ">\n >\n >"
- name: Standalone Indentation
desc: Each line of the partial should be indented before rendering.
data: { content: "<\n->" }
template: |
\
{{>partial}}
/
partials:
partial: |
|
{{{content}}}
|
expected: |
\
|
<
->

/
# Whitespace Insensitivity
- name: Padding Whitespace
desc: Superfluous in-tag whitespace should be ignored.
data: { boolean: true }
template: "|{{> partial }}|"
partials: { partial: "[]" }
expected: '|[]|'
