Historique du projet

Noboru Saito developed trdsql as a practical bridge between shell data files and relational query engines. The official documentation explains its internal processing as option and SQL interpretation, importing file names from SQL commands into a database, executing SQL, and exporting the result in a requested output format.

The project evolved from a text-query utility into a broader data conversion and analysis tool. The README documents direct SQL queries, file conversion mode, multiple input formats, multiple output formats, NULL handling, query files, compressed input and output, table-name shortcuts, joins, and selectable SQLite, PostgreSQL, or MySQL engines.

The author's release-history pages show a maturing project. Version 0.13.0, posted November 12, 2023, introduced a shorter `-t` table-name syntax useful for simple format conversion and addressed macOS arm64 binary builds. Version 1.0.0, posted April 8, 2024, was marked stable by the author and followed improvements such as multiple SQL execution added in v0.20.0.

Historique d'adoption

trdsql's adoption comes from the command-line data niche: users who have CSV, JSON, YAML, logs, or mixed tabular files but want real SQL operations without first creating a database schema. The official README documents binary downloads for Linux, Windows, and macOS, Docker usage, Go source builds, Homebrew, MacPorts, and FreeBSD packages.

The batch input records broader package-manager coverage, including Homebrew, MacPorts, Nix, and Scoop. That package spread matches the tool's cross-platform promise: a single CLI for shell users who want SQL-shaped inspection and conversion across operating systems.

Modes d'utilisation

In day-to-day use, trdsql runs SQL directly against files, reads from standard input, converts between formats with output flags, handles CSV headers and delimiters, parses JSON with jq expressions, and emits CSV, TSV, JSON, JSON Lines, LTSV, YAML, Markdown, ASCII tables, raw output, and other formats.

Its docs emphasize the tradeoff behind its power: trdsql imports data into an RDBMS before executing SQL, so it is not a streaming one-line-at-a-time filter. In exchange, users get real SQL semantics, joins, aggregation, window functions, configurable database engines, and format conversion in one package.

Pourquoi les passionnés de paquets s'y intéressent

For package nerds, trdsql sits in the same toolbox as `jq`, `xsv`, `mlr`, `q`, and `textql`, but it occupies the SQL-first corner. It is attractive when a user already thinks in SELECT, JOIN, GROUP BY, and database engine behavior but wants package-manager installation and shell-pipeline ergonomics.

The tool also shows the modern CLI packaging pattern: Go binary releases, Docker image, Homebrew and MacPorts formulas, Scoop availability, FreeBSD package notes, and source builds all coexist in the official installation docs.

Chronologie

• 2023: v0.13.0 release notes document `-t` table-name shorthand, macOS arm64 binary fixes, and build-environment changes.
• 2024: Official documentation site publishes trdsql overview, internals, configuration, SQL-engine, and format-conversion pages.
• 2024: v1.0.0 release notes state that the author considered trdsql stable enough for a 1.0.0 release.
