Docker

2026-01-30 (updated: 2026-02-11)

git

A fork of this repo: https://github.com/Gsync/jobsync.git

Updated to include automatic Job Application insertion from Notmuch Emacs email client.

Original Functionality

db is stored at `./prisma/dev.db`

it can be queried with sqlite3:

  • sqlite3 prisma/dev.db
  • .tables # List tables

SELECT id, subject, classification, status, confidence FROM EmailImport LIMIT 10;

.mode column
.headers on
SELECT subject, classification, confidence FROM EmailImport WHERE status='pending' LIMIT 5;

org-shop

Org-table based shopping list management with:

  • Mark items in shop files (C-c d m)
  • Generate shopping lists (C-c d g)
  • Sync prices back with history tracking (C-c d s)
  • Clear marks (C-c d c)

new functionality:

  • 1. add |--| bars on the ** history sub-heading.
  • 2. back-sync notes column.
