Hugo uses Chroma as its code highlighter. To enable it, you simply need to add the following lines to your config.toml file.
pygmentsCodefences = true pygmentsCodefencesGuessSyntax = true pygmentsStyle = "monokai"
If you want a different style than monokai, checkout the Chroma Style Gallery.
Example
Here is a code snippet example from my md file.
# Test syntax highlighting {{< highlight python "linenos=table,hl_lines=3 7-9,linenostart=1">}} my_list = [ 1, 5, 2, 4, 2, 5 ] seen = set() unique = [] duplicate = [] for x in my_list: if x not in seen: unique.append(x) seen.add(x) else: duplicate.append(x) print(duplicate, " are duplicates.") print(unique, " are unique.") {{< / highlight >}}
