Recently I had a need to color-code the text matched by a regular expression (regex) and had to resort to uploading a color-coded image of that text. You can also find the completed code on GitHub. 1 This is a very needed feature but the SO coders seem to go to great lengths to disable it. You can paste the CSS from the theme in the code CSS file.Īnd now, if you reload your application, you should see the theme in action, like the image below. In your application, create a new CSS file called code.css, and in the globals.css import it like so: 'code' You can find one here: HighlightJs themesĪnd once you found one, find the respective CSS styles on their GitHub repo We can then find or create a theme for these highlighting classes. The code block still looks the same, but if we look at the HTML created, we can see all kinds of new span elements with different classes. On the web, it may not always be rendered properly. We can still use the md variable in the same way and don't need to change much there: md. Syntax highlighted code blocks in Markdown (click to enlarge) The syntax highlighting depends on the editor you use. You can also use the formatting buttons in the bottom bar of your text window on OS X or the formatting keys in the Keyboard Bar of iA Writer for iOS. This lets you apply basic formatting by adding a few punctuation characters. Then we define a new variable that invokes the markdown package and includes the highlighter as a plugin. Markdown Guide Our apps use Markdown formatting. We changed the way we load the markdown package and the highlighter separately. Then head over to your pages/post/.js file and modify the imports section to look like this: import markdownIt from 'markdown-it' import highlightjs from 'markdown-it-highlightjs' const md = markdownIt (). To install the highlight package, run the following command. Since we are using markdown-it as our markdown parser, we can use highlightjs, an optional plugin. This script converts code blocks into separate span elements with classes to define what each part is. We can already parse code blocks however, they all look the same and have no highlighting.įor example, this image below shows how it would look: Use this GitHub repo as your starting point if you like to follow along. Let's try and add this feature to our new blog. Now that we created our markdown powered Next.js blog, we want to show off code blocks.Ĭode blocks like you would have seen on this website look like this: function $initHighlight ( block, cls ) export $initHighlight Making markdown code blocks look nice with a highlighter plugin 3 Feb, 2022
