At work, the RDBMS de-jour for many internal apps is - for better or worse - Oracle® Database.
However, the provided tooling for Oracle (sqlplus) lacks several features that I consider to be essential to be productive (e.g. schema-aware auto-complete for SQL-statements) and since there didn't seem to be any viable open-source alternatives I started a side-project to build something better.
After being used internally for over a year the result of that project, okcli, was made publicly available under a BSD-3 license earlier this week and announced on the company tech blog. The gif below shows it in action.
