Raku, Go, Chroma, Germanium, Hugo and my blog

When I created my Raku programming language website with Hugo static site generator, I had to manually create the syntax highlighted html files for code examples shown in the front page, because Hugo used Chroma(written in Go and uses a mostly similar API to Pygments) for syntax highlighting which didn't support Raku. So I opened an issue on Chroma, the discussion showed that you cannot just convert the Raku lexer from Pygments to Chroma; You would need to create some functions manually, and Chroma needed a new Emitter interface which would take the LexerState as an argument, because Raku has some complex syntax; the Raku lexer in Pygments had functions for finding closing brackets matching the opening brackets, and for regex nesting in tokens, regexes and rules.

An improved flycheck-raku now available on melpa [Emacs]

Recently I forked the flycheck-raku (by @widefox) to the Raku GitHub organization. And did some improvements to it and published it on melpa, so others can easily install and update it. For those who don't know, flycheck is a tool for syntax checking Gnu Emacs buffers. You can install flycheck-raku using use-package: (use-package flychek-raku :ensure t) New features Project detection Previously if you used flycheck-raku on a project, it would show errors on use SomeModule;, even though the module was in the lib directory of the project.

How to type Raku unicode characters in Emacs

Raku programming language uses some unicode characters as operators, quotation marks, etc. In this post I'm going to explain how to type those characters in Emacs using input methods. First, you might want to see a list of those characters and their ASCII equivalents here. There is also a doc for entering unicode characters. You may specifically want to look at XCompose for a system-wide solution. There are at least two input methods you can use to enter the unicode characters used in Raku.
