Resources metadata example
{{< code-toggle copy="false">}} title: Application date : 2018-01-25 resources :
- src : "images/sunset.jpg" name : "header"
- src : "documents/photo_specs.pdf" title : "Photo Specifications" params: icon : "photo"
- src : "documents/guide.pdf" title : "Instruction Guide"
- src : "documents/checklist.pdf" title : "Document Checklist"
- src : "documents/payment.docx" title : "Proof of Payment"
- src : "**.pdf" name : "pdf-file-:counter" params : icon : "pdf"
- src : "**.docx" params : icon : "word" {{</ code-toggle >}}
From the example above:
sunset.jpg
will receive a newName
and can now be found with.GetMatch "header"
.documents/photo_specs.pdf
will get thephoto
icon.documents/checklist.pdf
,documents/guide.pdf
anddocuments/payment.docx
will getTitle
as set bytitle
.- Every
PDF
in the bundle exceptdocuments/photo_specs.pdf
will get thepdf
icon. - All
PDF
files will get a newName
. Thename
parameter contains a special placeholder:counter
, so theName
will bepdf-file-1
,pdf-file-2
,pdf-file-3
. - Every docx in the bundle will receive the
word
icon.
{{% warning %}}
The order matters --- Only the first set values of the title
, name
and params
-keys will be used. Consecutive parameters will be set only for the ones not already set. For example, in the above example, .Params.icon
is already first set to "photo"
in src = "documents/photo_specs.pdf"
. So that would not get overridden to "pdf"
by the later set src = "**.pdf"
rule.
{{%/ warning %}}
The :counter
placeholder in name
and title
The :counter
is a special placeholder recognized in name
and title
parameters resources
.
The counter starts at 1 the first time they are used in either name
or title
.
For example, if a bundle has the resources photo_specs.pdf
, other_specs.pdf
, guide.pdf
and checklist.pdf
, and the front matter has specified the resources
as:
{{< code-toggle copy="false">}} resources src = "*specs.pdf" title = "Specification #:counter" resources src = "**.pdf" name = "pdf-file-:counter" {{</ code-toggle >}}
the Name
and Title
will be assigned to the resource files as follows:
Resource file | Name |
Title |
---|---|---|
checklist.pdf | "pdf-file-1.pdf |
"checklist.pdf" |
guide.pdf | "pdf-file-2.pdf |
"guide.pdf" |
other_specs.pdf | "pdf-file-3.pdf |
"Specification #1" |
photo_specs.pdf | "pdf-file-4.pdf |
"Specification #2" |
