Jesus +date: 2022-08-29 +slug: hello-world +title: Hello, world! +--- + +I have been thinking of starting a blog for a while, mostly to write +about stuff that makes no sense to publish academically, but also to +improve my writing skills. I expect to mostly write about Programming, +Emacs, Linux, and other tech topics. But we will see where it goes. + +In this first post I will quickly go over the implementation and +deployment of this site. Note that, you can find the code for this site +at <https://git.adbjesus.com/website>. + +### Static Site Generator + +Since this site will contain static content, I've decided to go with a +static site generator. In particular, I chose +[Zola](https://getzola.org). The main reason for using Zola and not +something else is that I am familiar with its implementation language +(Rust). This can allow me to easily contribute to the project to fix any +issue or scratch any itch. + +In terms of styling, I'm using simple templates and CSS I implemented +myself, which match the light/dark system theme option set by the user. +Something I am not yet doing, is using syntax highlighting for code in +blog posts. Although Zola supports this, it does not support some of the +languages that I want, such as Emacs Lisp and Nix, and it is using old +and buggy Sublime syntaxes. There is currently an [open +issue](https://github.com/getzola/zola/issues/1787) to replace the +current system. Another option, would be to use a javascript based +syntax highlighter. However, I would rather keep my site +javascript-free. As a result, since I don't consider it to be a critical +feature for now, I will not implement any syntax highlighting for the +time being. + +### Using Org + +One issue I had with Zola is that it does not suppor +[Org](https://orgmode.org) for writing content (see this +[issue](https://github.com/getzola/zola/issues/909)). However, I would +prefer to use it instead of markdown because I prefer and am more +comfortable with its syntax, but also because I want to be able to use +[Org Babel](https://orgmode.org/worg/org-contrib/babel/) to execute code +within the `.org` file directly when writing posts for which executing +code is useful. + +Nonetheless, this proved not to be an issue for my simple use case +because I can automatically convert `.org` files to `.md` files +(following the [CommonMark](https://commonmark.org/) spec) using +[pandoc](https://pandoc.org), and the +[ox-pandoc](https://github.com/emacsorphanage/ox-pandoc) package for +Emacs. To setup ox-pandoc to export `.org` files to CommonMark I have +the following in my Emacs configuration: + +``` elisp +(use-package ox-pandoc + :ensure t + :after org + :custom + (org-pandoc-menu-entry + '((?c "to cmk." org-pandoc-export-to-commonmark) + (?C "to cmk and open." org-pandoc-export-to-commonmark-and-open)))) +``` + +Then, I put the `index.org` for a blog post inside a dedicated folder +for that post: + +``` example +content +└── blog + └── 01-hello-world + ├── index.org + └── ... // other files +``` + +The `index.org` file includes some metadata in its header for both Zola +and ox-pandoc. For example, for this post I'm using the following +header: + +``` org +#+TITLE: Hello, world! +#+DATE: 2022-08-25 +#+PANDOC_METADATA: slug:hello-world +#+PANDOC_EXTENSIONS: commonmark+yaml_metadata_block +#+PANDOC_OPTIONS: standalone:t +#+PANDOC_OPTIONS: shift-heading-level-by:2 +``` + +The `TITLE`, `DATE`, and `PANDOC_METADATA` fields are added to the +exported markdown metadata block. To add the metadata block to the +generated markdown file we set the `yaml_metadata_block` pandoc +extension in `PANDOC_EXTENSIONS`, and the `standalone:t` option in +`PANDOC_OPTIONS`. The last line is used to start the generated headings' +levels at 3 for styling purposes. + +Finally, I use the `C-c C-e p c` shortcut to generate the markdown file, +which goes into the same folder, i.e.: + +``` example +content +└── blog + └── 01-hello-world + ├── index.org + ├── index.md + └── ... // other files +``` + +You can find the Org source for this post [here](index.org). + +### Deploying with Nix + +I deploy this site to my [NixOS](https://nixos.org) server using the +declarative NixOS configuration capabilities.
