• I introduced the diary page creation system used in side of well to my own project.

Introduction memo

  • Latest code as of 2022-05-21
  • This needs to be pre-bundled because it is written in TypeScript and is split into multiple files and uses third-party libraries as well
  • The design and title of the diary page is cut out of the function, so if you want to change it, just change this.
  • All necessary files have been transcribed on this page.
    • You can also do URL imports across projects, leaving all but script.ts and template.ts, which you modify for your own use, at the well end.
    • I just collected them all because I felt weird using them without knowing the whole picture.
  • Use this for bundles.
    • /villagepump/scrapbox-bundler
    • Iā€™m just doing deno bundle <url> | esbuild --minify, so if you have a development environment at hand, thatā€™s fine.
    • Itā€™s not like the results of this build are cached for 10 years unless they go into a CDN and explicitly refresh, so now Iā€™m manually pasting the finished script into Scrapbox.
      • Itā€™s a bit of a pain, but I donā€™t plan to do a lot of this work in the future, so Iā€™m not inclined to automate it.
    • Accessing this URL will run the build.
    • I put the finished product at the end of this page under the name min.js, which you can call from your UserScript.
  • [/villagepump/why not unpinned in pin-diary](https://scrapbox.io/villagepump/why not unpinned in pin-diary).
    • If the title format is changed, the regular expression that determines the title format must also be changed.
  • Meaning of deps.ts
  • 2022-05-30
    • Unexplored Junior Scrapbox to create a page with a workroom template.
    • After that, I moved it to /mitoujr-script/times-dev instead of this page because there was a need to modify the body part ā€œto make it not pinnedā€.
