With this playground you can test the (currently indev) programming language lapyst.

Note that you'll be able to refer (declare) functions from the libc as provided by the wasi-sdk.

About stored data

This pages does not use cookies. However it uses the localStorage and indexedDB API's to localy store some data.
This data will never been send to any servers and completly stay on your local device, and is ensured by the localStorage API / your browser.

The data stored is:

• localStorage:
  • code_snippet - the current sourcecode of the playgrounddepreacted; data will be migrated to indexedDB and removed
  • current_snippet - id (or more accurately, the creation date) of the snippet currently loaded by the playground
• indexedDB:
  • database lapyst_playground - holds all data the playground stores
    • snippets - all snippets as viewable via the 'History' button in the top bar
      • code - the code of the snippet
      • desc - an optional description
      • createdAt - creationdate; also acts as primary identifier
      • lastModified - the date of the last modification
      • lastOpened - the date when the snippet was last opened; used to list the snippets in the history popup

About the share feature

Additionally this playground supports a "share"-feature, where you can share any snippets stored locally with other people.

This works by generating a link that contains all the information in an queryparam; no data is stored onto servers.

All data is contained inside the load query parameter as a base64 encoded JSON object.

Data included:

• code - the code of the snippet to share
• desc - the snippet's description
• createdAt - date where the snippet was created
• lastModified - date where the snippet was last edited
