clayoven
clayoven is a beautiful static site generator with a carefully curated set of features. It has been built at a glacial pace, over a period of eight years, as my website expanded in content. I have a spread of mathematical notes, both typeset and handwritten, software-related posts, and some wider-audience articles; it suffices to say that clayoven is good on all three fronts. The source files are written in "claytext", a custom format built for elegance and speed.
rdoc documentation is available at clayoven.artagnon.com.
Unique features
- Small! ~500 lines of well-written Ruby.
- Beautiful and easily extensible markup, with a dedicated vscode plugin for it.
- Automatically picks timestamps from git history, respecting moves.
- Server-side rendering of math, including commutative diagrams, via MathJaX and XyJaX.
Getting started
There is no published gem. To get started, clone, run bundle
to install the required gems, and put bin/clayoven
in $PATH
. Then, run clayoven init
in a fresh directory. To start writing, install vsclay for vscode, which will provide the necessary syntax highlighting, and trigger-[incremental build]-on-save functionality.
The claytext format
Here's an excerpt of claytext, illustrating the main features:
The site-generation engine
All site content is split up into "topics", to put in the sidebar, each of which can either serve as an index to a collection of ContentPages
(as a bunch of .clay
files in a subdirectory with the name #{topic}
), or a single IndexPage
(named #{topic}.index.clay
). index.clay
is special-cased to serve as the root of the site.
So, if you have these files,
.vscode/... # provided by `init`
.htaccess # provided by `init`
lib/... # provided by `init`
design/template.slim # provided by `init`
index.clay # provided by `init`
scratch.index.clay # provided by `init`
404.index.clay # provided by `init`
blog.index.clay
blog/personal/1.clay
blog/math/1.clay
colophon.index.clay
clayoven automatically builds a sidebar with index
, blog
and colophon
(each of which are instances of IndexPage
). /blog
will have links to the posts /blog/personal/1
and /blog/math/1
(each of which are instances of ContentPage
), under the titles personal
and math
(the "subtopics"). If there multiple ContentPage
entries under an IndexPage
, the latter simply serves to give a introduction, with links to articles automatically appearing after the introduction. IndexPage
and ContentPage
are run through the same design/template.slim
, and the template file has access to the accessors.
The engine works closely with the git object store, and builds are incremental by default; it mostly Just Works, and when it doesn't, there's an option to force a full rebuild. The engine also pulls out the created-timestamp (Page#crdate
) and last-modified-timestamp (Page#lastmod
) from git, respecting moves. ContentPages
are sorted by crdate
, reverse-chronologically, and IndexPages
are sorted alphabetically.
Usage
-
clayoven init
to generate the necessary template website. -
clayoven
to generate html files incrementally based on the current git index. -
clayoven aggressive
to regenerate the entire site along with asitemap.xml
; run occassionally. -
clayoven httpd
to preview your website locally.
Configuration
-
.clayoven/sitename
is URL of the site, excluding thehttps://
prefix. -
.clayoven/hidden
is a list ofIndexFiles
that should be built, but not displayed in the sidebar. You would want to use it for your 404 page and drafts. -
.clayoven/tz
is a timezone-to-location mapper, with lines of the form+0000 London
. clayoven digs through the git history for locations, and exposes aPage#locations
. -
.clayoven/subtopic
is a [subtopic directory]-to-subtitle mapper, with lines of the forminf ∞-categories
.
The claytext processor
The claytext processor is, at its core, a paragraph-processor; all content must be split up into either plain paragraphs, or "fences" (multiple paragraphs delimited by start and end tokens). The function of most markers should be evident from the scratch.html
produced by a clayoven init
. The format is strict, and the processor doesn't like files with paragraphs wrapped using hard line breaks.
Transforms::LINE
matches paragraphs where all lines begin with some regex, and Transforms::Fenced
match fences (could be multiple paragraphs) that start and end with the specified tokens. In addition to this, there are inline markdown markers `...`
and [...](...)
, for content that is to be put in <mark>
and <a>
, respectively.
Tips
- Check in the generated html to the site's repository, so that eyeballing
git diff
can serve as a testing mechanism. - If you accidentally commit
.clay
files before running clayoven, running it afterward will do nothing, since it will see a clean git index; you'll need to run the aggressive variant. - Importing historical content is easy; a
git commit --date="#{historical_date}"
would give the post an appropriate creation date that will be respected in the sorting-order.
Planned features, and anti-features
- Intellisense support for MathJaX in vsclay.
- Anti: extending claytext in ways that would necessitate an ugly implementation.
