Add a hint.concept.* tier-3 layer surfaced when the cursor sits inside a recognized clause (referential actions, 1:n/m:n cardinality, primary key, unique, check, foreign key), layered beneath the per-form block. New Node::Concept grammar wrapper records clause byte-spans; concept_topic_at_cursor resolves the innermost containing span. Examples are mode-keyed so they stay syntax-correct in both simple and advanced mode. Draft ADR (number at merge).

# Changelog
|
|
|
|
All notable, user-facing changes to RDBMS Playground are documented here.
|
|
|
|
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
|
|
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0/).
|
|
|
|
## [Unreleased]
|
|
|
|
### Added
|
|
- Pressing **F1** while the cursor sits inside a clause now adds a short
|
|
"About this clause" explanation beneath the command hint — covering
|
|
referential actions (`on delete`/`on update`), one-to-many and
|
|
many-to-many relationships, primary keys, unique and check constraints,
|
|
and foreign keys. The example shown matches whichever mode you're in.
|
|
- `help` now covers the advanced-mode SQL commands: `help select`, `help with`,
|
|
and the SQL forms of `insert` / `update` / `delete` / `explain` show their own
|
|
syntax, and the full command list is grouped into "Simple-mode commands" and
|
|
"Advanced-mode (SQL) commands" sections.
|
|
- Install via **Scoop**, **Homebrew**, and **winget** in addition to the
|
|
existing channels.
|
|
- Tier-4 end-to-end test suite that exercises the real application in a
|
|
terminal (cold launch, save/reopen, export/import, undo) — guards against
|
|
regressions the unit and render tests can't see.
|
|
- Automated colour-accessibility checks: every theme now has its
|
|
foreground/background contrast and its syntax-colour distinctness verified
|
|
on each build.
|
|
|
|
### Removed
|
|
- The `blob` column type. It could be declared but never given a value
|
|
(there was no way to type a binary value in either mode), so it was a
|
|
dead end with nothing to teach. The vocabulary is now nine types.
|
|
Existing projects that used a `blob` column still open — the column is
|
|
converted to `text` on first load (a backup of the original project file
|
|
is kept alongside it).
|
|
|
|
### Fixed
|
|
- Pasting or scripting several commands at once no longer occasionally
|
|
rejects a valid simple-mode `insert` — submitted right after adding a
|
|
column — as though it were advanced-mode SQL.
|
|
- **Light theme:** string-literal and flag colours in syntax highlighting
|
|
were below the WCAG-AA contrast bar; both are now legible. Two dark-theme
|
|
token colours that were hard to tell apart have been separated.
|
|
- Windows `install.ps1` now works on the in-box Windows PowerShell 5.1 and
|
|
updates `PATH` for the current session.
|
|
|
|
## [0.2.0] - 2026-06-17
|
|
|
|
### Added
|
|
- **Version surfaces:** a `--version` / `-V` command-line flag and an in-app
|
|
`version` command, both reporting the build's exact version.
|
|
- **Installation options:** publish to crates.io (`cargo install
|
|
rdbms-playground`), `cargo binstall` support, a one-line `curl | sh`
|
|
installer, and a Windows `install.ps1` — so you no longer have to hand-pick
|
|
a release asset.
|
|
- **Documentation & landing site** at <https://relplay.org> — the canonical
|
|
user guide plus screencast demos.
|
|
- A demonstration-mode key alias (Ctrl-G acting as F1) so screencasts can
|
|
show the in-app help/hint key.
|
|
|
|
### Fixed
|
|
- Corrected several errors in the contextual-hint help text.
|
|
|
|
## [0.1.0] - 2026-06-15
|
|
|
|
First public release: the cross-platform terminal sandbox for learning
|
|
relational-database concepts — tables, keys, relationships, indexes, queries
|
|
and query plans — in a guided simple mode or a full advanced (SQL) mode, with
|
|
projects, undo, and export/import.
