Jekyll post not generated

Question

I am trying to add a new post to my Jekyll site, but I cannot see it on the generated pages when I run jekyll serve.

What are some common reasons for a

Answer 1

I have written Rspec tests for my blog that express these rules:

require 'spec_helper'
require 'yaml'

# Documented at https://jekyllrb.com/news/2017/03/02/jekyll-3-4-1-released/
post_regex = %r!^(?:.+/)*(\d{2,4}-\d{1,2}-\d{1,2})-(.*)(\.[^.]+)$!

def date_in_front_matter(date)
  return date if date.is_a?(Date)
  return date.to_date if date.is_a?(Time)
  return Date.parse(date) if date.is_a?(String)
end

describe 'posts' do
  Dir.glob("_posts/*md").each do |file|
    basename = File.basename(file)

    context basename do
      front_matter = YAML.load(File.read(file).split(/---/)[1])

      it 'filename must match documented post regex' do
        expect(basename).to match post_regex
      end

      it 'date in file name same day as date in front matter' do
        date_in_file_name = Date.parse(post_regex.match(basename).captures[0])
        expect(date_in_front_matter(front_matter['date'])).to eq date_in_file_name
      end

      it 'title in front matter should not contain a colon' do
        expect(front_matter['title']).to_not match /:/
      end

      it 'front matter should not have published: false' do
        expect(front_matter['published']).to_not be false
      end
    end
  end
end

This may be of use to others as I was losing a lot of time due to typos in the date etc.

These tests along with the rest of the Rspec config can be seen in context here.

Just to add one more reason, when you move an article from _drafts to _post, you sometimes need to delete the _site for the article to be regenerated.

In my case it often happens that _site will not be entirely deleted before re-generation so the new article won't appear.

Anyway rm -rf _site and bundle exec jekyll serve works :)

If you are unable to track the file in --verbose and if the file is silently ignored then try removing collections_dir in the config.yml file. That solved the issue for me.
