> "I'll just read a file, swap out some variables, and write some HTML." – Famous last words

I'm actually living the dream. The key: directly author html. I.e. the above file contains html.

Cool! Also, carrying forward the post author's tongue-in-cheek humour... I see your lua and raise you ~350 lines of Bash (excludes HTML templates). Take a good hard look at this shite [0]. Have you seen anything that is more obviously HTML-about-to-be-expanded-into-a-full-page?

    shite_template_standard_page_wrapper() {
        cat <<EOF
    <!DOCTYPE html>
    <html lang="en" prefix="og: https://ogp.me/ns#">
      $(shite_template_common_head)
      <body>
        <div id="the-very-top" class="stack center box">
          $(cat -)
          $(shite_template_common_footer)
        </div>
      </body>
    </html>
    EOF
    }
And, unlike PHP or whatever... have you ever seen more composable templating, as in functional programming?

    cat ./sample/hello.html |
      shite_template_common_default_page

    # Or..

    cat ./sample/hello.org |
      pandoc -f org -t html |
      shite_template_common_default_page
Just imagine all the pipelined pre/post-processor possibilities.

I really enjoyed reading this, the descent into madness sure did make for a fun ride. Lisp + rabbit holes gotta be one of my favourite literary genres. :D

I feel seen... who else is with me?

OR... you could just use inotify again... Behold this abomination (that works so well (on my machine) I can't believe it):

  __shite_hot_cmd_browser_refresh() {
      local window_id=${1:?"Fail. We expect window ID to be set in scope."}
  
      printf "%s\n" \
             "key --window ${window_id} --clearmodifiers 'F5'"
  }
  
  __shite_hot_cmd_goto_url() {
      local window_id=${1}
      local url=${2}
  
      printf "%s\n" \
             "key --window ${window_id} --clearmodifiers 'ctrl+l'" \
             "type --window ${window_id} --clearmodifiers --delay 1 ${url}" \
             "key --window ${window_id} --clearmodifiers 'Return'"
  }
... and a few functions later ...

  __shite_hot_cmd_exec() {
      # In debug mode, only show the actions, don't do them.
      if [[ ${SHITE_BUILD} == "hot" ]]
      then stdbuf -oL grep -v '^$' | __tap_stream | xdotool -
      else cat -
      fi
  }
  
  shite_hot_browser_reload() {
      local browser_window_id=${1:?"Fail. Window ID not set."}
      local base_url=${base_url:?"Fail. Base URL not set."}
      __shite_hot_cmd_public_events ${browser_window_id} ${base_url} |
          __shite_hot_cmd_exec
  }
... and finally ...

    # RUN PIPELINE
    shite_hot_watch_file_events ${watch_dir} |
        __shite_events_dedupe |
        __tap_stream |
        tee >(shite_hot_build ${base_url}) |
        # Perform hot-reload actions only against changes to public files
        tee >(shite_hot_browser_reload ${window_id} ${base_url})
