Description

Use case

rtk psql exists and compresses Postgres table output. The Microsoft sqlcmd CLI (MSSQL) produces structurally identical noise — column header separators, padding, trailing whitespace — and is heavily used in .NET / Windows-server stacks.

Frequency

rtk discover on a 30-day Claude Code history: 208 invocations of sqlcmd, currently completely unfiltered.

Suggested behaviour (mirroring rtk psql)

  • Strip ASCII table borders / dash separator rows.
  • Compress repeated whitespace inside cells.
  • Honour -Q/-i flags transparently.
  • Optionally: prefer JSON via sqlcmd -y 0 + a JSON-aware variant, similar to what rtk aws does with --output json.

Filename suggestion: src/proxies/sqlcmd.rs, registered analogously to psql.rs.

Contributor guide

Research direction
Study the implementation of rtk psql in src/proxies/psql.rs, then create a similar proxy for sqlcmd that strips table borders and compresses whitespace. Handle Q and i flags. Consider adding a JSON aware variant.
