redcarpet | The safe Markdown parser

I am using Redcarpet to render in a webpage data introduced by the User.

I see that it is very easy for the User to introduce malicious HTML code.

I am trying different Redcarpet initializer options to prevent any possible malicious code to be renderered in the output but nothing is working:

I am trying to run Jekyll and I have the following contents in the Gemfile

I'm following the instructions on https://github.com/niku/markdown-preview-eww

I have installed markdown-preview-eww using MELPA, redcarpet using gem, restarted Emacs and opened a .md file. However I don't understand how am I supposed to "Execute markdown-preview-eww".

The search engines haven't helped me out.

The issue: You can click on ‘Older’ to get to the second page of older blog, i.e. https://www.bgigurtsis.com/blog/page2/. However, clicking on ‘Newer’ once on that second page takes you to the homepage https://www.bgigurtsis.com, as opposed to the page you were just on https://www.bgigurtsis.com/blog

My setup I’m using a Jekyll theme hosted on AWS Amplify. Usually for this theme the index page is where all the blog posts are. I changed this so the index page is a ‘welcome’ post with a hyperlink to the blog instead.

To achieve this:

1. I moved index.html (pagination code) from my root dir into a folder called ‘blog’
2. Added an index.md (welcome page) in my root directory.
3. Added this code to my _config.yml: paginate_path: “/blog/page:num”

Here’s the folder structure:

My app works locally, however when I try to deploy to Heroku, I get a Sprockets::FileNotFound: couldn't find file 'angular' with type 'application/javascript' error.

I have tried precompiling with RAILS_ENV=production bundle exec rake assets:precompile and purging my build cache with heroku builds:cache:purge -a findum, but still no luck. I recently migrated from Bower to Yarn– not sure if my asset path is the problem?

Has anyone run into a similar error that they were able to resolve? So many thanks 🙏.

This is my application.js :

I'm using redcarpet gem to render some markdown text to html, a portion of the markdown was user inserted, and they typed in a totally valid special character (£), but now when rendering it I get a: Encoding::UndefinedConversionError "\xC2" from ASCII-8BIT to UTF-8

I know it's the £ sign because if I replace it in the text to render then it all works. but they might be inserting other special characters.

I'm not sure how to deal with this, here's my code building the html:

I am getting an error trying to run Spree 3.3 after following the steps to upgrade from 3.2 at https://guides.spreecommerce.org/developer/upgrades/three-dot-two-to-three-dot-three.html. I updated the Gemfile, ran bundle update, and then installed the migrations. I couldn't even run the migrations because of this same error:

I am having some trouble mapping (displaying) existing tuples in my local mysql database on my front end (Reactjs). I am receiving the following error: "TypeError: Cannot read property 'name' of null".

I was able to display these records in the past, so I know I am close, but have spent all day trying to get just the existing records to show up in the view, and so am hoping for some guidance. I am not very familiar with reactjs, so I have a feeling the problem may reside somewhere on that end. I am able to successfully query the database via terminal and see respective reviews. Any information would be greatly appreciated!

When running bundle exec jekyll serve, I get the following: Server address: http://0.0.0.0:4000//

Where does // come from in my config? How do I get rid of it to get http://0.0.0.0:4000/ ?
