I am new to Jekyll. I have a post with the following yml front matter:

---
layout: images-grid
title: Grid Sample
image: "/imgs/image1.jpg"
---

I would like to create .rb plugin that identifies all the posts with "layout = images-grid" and adds the height and the width of the image as a yaml metadata so the height and the width will be available to the liquid templates.

Is there any way to do this?

could you not do something like this in your file?

{% if page.layout == images-grid %}
// do something
<img src="{{image}}" class="image-class"/>
{% endif %}

I'm looking for something similar (well not really similar, but the goal is the same, use a plugin to edit the front-matter of a post or posts).

So far the only option that I've found is to actually use the ruby File class to open and edit the file. So something like:

fileHandler = File.open("2013-11-23-post-title.html", "w+")

and then read in lines, editing/adding your new content to the front matter as necessary, i.e.:

fileHandler.puts "height: 480px\n width: 640px"

It would be nicer/ideal if the front-matter was available for manipulation as an attribute of the page or post object, but I don't think it is. I'm going to check the project page on github to see if there is already a feature request open for that.
