Post excerpts
There is now an easier way to show only portions or excerpts of your blog posts on your homepage, and any other areas of your site where you wish to show or preview your posts content.
To mark the point at which your post should be truncated when being previewed, I have shamelessly stolen the <!–– more ––> marker idea used in Jekyll.
How to create a post excerpt
When writing the markdown for your blog post, you can simply include <!–– more ––> on any line, and everything after that line will be removed in post previews (such as those on the Homepage). A "Read more about X..." link will appear at the end of the preview instead of <!–– more ––>.
How it works
The post_preview function in .app/generate_post_content.bash truncates the post content, and creates a $page_excerpt variable, which is used in the _post_preview.mustache template as {{page_excerpt}}.
If you create other templates or template partials in which you wish to show post previews, you can use:
my_html="`post_preview posts/2019/03/22/some-file.mdsh`"
And in your template you can then show the post excerpt/preview using {{my_html}}
