Miller docs

Why use Mkdocs

• Connects to https://miller.readthedocs.io so people can get their docmods onto the web instead of the self-hosted https://johnkerl.org/miller/doc. Thanks to @pabloab for the great advice!
• More standard look and feel -- lots of people use readthedocs for other things so this should feel familiar.
• We get a Search feature for free.
• Mkdocs vs Sphinx: these are similar tools, but I find that I more easily get better desktop+mobile formatting using Mkdocs.

Contributing

• You need pip install mkdocs (or pip3 install mkdocs) as well as pip install mkdocs-material.
• The docs include lots of live code examples which will be invoked using mlr which must be somewhere in your $PATH.
• Clone https://github.com/johnkerl/miller and cd into docs6/ within your clone.
• Overview of flow:
  • docs6/src has *.md.in files containing markdown as well as directives for auto-generating code samples.
  • A genmds script reads docs6/src/*.md.in and writes docs6/src/*.md.
  • The mkdocs build tools reads docs6/src/*.md and writes HTML files in docs6/site.
• Quick-editing loop:
  • In one terminal, cd to this directory and leave mkdocs serve running.
  • In another terminal, cd to the src subdirectory of docs6 and edit *.md.in.
  • Run genmds to re-create all the *.md files, or genmds foo.md.in to just re-create the foo.md.in file you just edited.
  • In your browser, visit http://127.0.0.1:8000
  • This doesn't write HTML in docs6/site; HTML is served up directly in the browser -- this is nice for previewing interactive edits
• For-publish editing loop:
  • Leave one terminal open as a place you will run mkdocs build
  • In one terminal, cd to the src subdirectory of docs6 and edit *.md.in.
  • Generate src/*.md from src/*.md.in, and then from that generate the site/*/*.html:
    • Run genmds to re-create all the *.md files, or genmds foo.md.in to just re-create the foo.md.in file you just edited.
    • In the first terminal, run mkdocs build which will populate the site directory.
    • See also ./regen.sh which combines the genmds and mkdocs build steps.
  • This does write HTML in docs6/site.
  • In your browser, visit file:///your/path/to/miller/docs6/site/index.html
  • Link-checking:
    • sudo pip3 install git+https://github.com/linkchecker/linkchecker.git
    • cd site and linkchecker .
• Submitting:
  • Do the for-publish editing steps -- in particular, docs6/src/*md.in and docs6/src/*md are both checked in to source control.
  • git add your modified files, git commit, git push, and submit a PR at https://github.com/johnkerl/miller.

Notes

• CSS:
  • I used the Mkdocs Readthedocs theme which I like a lot. I customized docs6/src/extra.css for Miller coloring/branding.
• Live code:
  • I didn't find a way to include non-Python live-code examples within Mkdocs so I adapted the pre-Mkdocs Miller-doc strategy which is to have a generator script read a template file (here, foo.md.in), run the marked lines, and generate the output file (foo.md). This is genmds.
  • Edit the *.md.in files, not *.md directly.
  • Within the *.md.in files are lines like GENMD_RUN_COMMAND. These will be run, and their output included, by genmds which calls the genmds script for you.
