imaging VS chroma

There are a number of projects using manipulation libraries like https://github.com/disintegration/imaging which is already MIT licensed, and then there are various transcoders which I am unfamiliar with, but you will want to consider if you add enough value to make use of those unimportant to the decision to pay.

Sorry for not putting this code in my post. The input isn't from an *os.File, but rather from HTTP request captured by gin and it's on MultipartForm.File. The reason being why I had to do all these shenanigans is because I have to preprocess the image using this module: https://github.com/disintegration/imaging

Imaging

In Hugo and its built-in Chroma syntax highlighting, a code block begins with:

Hugo -> goldmark -> goldmark-highlighting -> chroma

I've used a markdown to html converter to convert my blog posts into HTML with very nice and customizable code samples... in my case I used Go's Blackfriday library with bfchroma[1] doing syntax highlighting with Chroma[2]. To add your language to Chroma you have to provide a lexer, which in turn is written in Pygments[3] syntax.

quick for generating Html and syntax highlighting code blocks

Chroma

For books from other publishers, I am just hardcoding language directly on an ad hoc basis. I briefly considered off-loading language detection to a library like chroma, but that might be too much work for little benefit.

Great blog, you should definitely do research on how you could implement a syntax highlighter for the code parts. Go Hugo for example, uses Chroma. Nice work 👍
