ADR-0001: Language and TUI framework
Status
Accepted
Context
RDBMS Playground is a cross-platform terminal application aimed at learners. It needs to feel fast, polished, and colourful, install cleanly on Linux, macOS, and Windows, and ship as a single binary with no runtime dependencies.
Beyond TUI rendering, the application has substantial SQL-handling needs: syntax highlighting, parsing user input to distinguish app DSL commands from SQL, rewriting simplified types into backend types, and analysing query plans for the teaching features.
Two stacks were realistic candidates:
- Rust + Ratatui + Crossterm — strong cross-platform terminal
support, single static binary, mature ecosystem. Crucially,
sqlparser-rsis a high-quality dialect-aware SQL parser directly applicable to the parsing, highlighting, and query analysis features. - Go + Bubble Tea (Charm) — excellent default aesthetics,
single static binary, easy distribution. Lacks an equivalent to
sqlparser-rs; SQL parsing would need to be written from scratch or wrap a less suitable library.
Decision
Use Rust with Ratatui and Crossterm for the TUI, with
sqlparser-rs for SQL parsing and rusqlite for the database
layer. Distribute as prebuilt binaries via GitHub releases plus
package managers (cargo binstall, Homebrew, Scoop, winget).
Consequences
- Single static binary on all three target platforms.
- Strong fit between SQL-heavy features and the Rust SQL ecosystem
(
sqlparser-rs,rusqlite). - Slightly steeper contributor on-ramp for developers unfamiliar with Rust compared to Go.
- TUI styling will require explicit work to match the polish that Bubble Tea / Lipgloss give for free; budget for it in the design pass.
Amendment 1 — Distribution channel is open after the Gitea migration (2026-06-09)
The Decision block above assumed prebuilt binaries would ship "via
GitHub releases plus package managers." Since then the repository has
been migrated off GitHub to a self-hosted Gitea instance
(git.lazyeval.net/oli/rdbms-playground), and tea is the forge CLI
in use. The "GitHub releases" half of that sentence is therefore no
longer a settled assumption.
This amendment does not pick a replacement. Binary distribution is
not built yet (no release pipeline, no CI — requirements.md TT5/E*
remain open), so the channel for prebuilt binaries is an open
choice — Gitea releases, a GitHub mirror's releases, or both — to be
settled by a dedicated ADR when distribution is actually implemented.
The package-manager channels named in the Decision (cargo binstall,
Homebrew, Scoop, winget) are independent of the forge and are
unaffected.
(For the same supersede-don't-rewrite reason, the Decision block also
still names sqlparser-rs, which ADRs 0030–0036 replaced with a
hand-rolled grammar; that is recorded there, not by editing this ADR.)
