# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [v0.30.0] - 2003-03-27
### Added
- [#164]: Implemented `unique` function ([docs](https://sq.io/docs/query#unique)):
```shell
$sq '.actor | .first_name | unique'
```
This is equivalent to:
```sql
SELECT DISTINCT first_name FROM actor
```
- Implemented `count_unique` function ([docs](https://sq.io/docs/query#count_unique)).
```shell
$ sq '.actor | count_unique(.first_name)'
```
### Changed
- The `count` function has been changed ([docs](https://sq.io/docs/query#count))
- Added no-args version: `.actor | count` equivalent to `SELECT COUNT(*) AS "count" FROM "actor"`.
- **BREAKING CHANGE**: The "star" version (`.actor | count(*)`) is no longer supported; use the
naked version instead.
- Function columns are now named according to the `sq` token, not the SQL token.
```shell
# previous behavior
$ sq '.actor | max(.actor_id)'
max("actor_id")
200
# now
$ sq '.actor | max(.actor_id)'
max(.actor_id)
200
```
## [v0.29.0] - 2023-03-26
### Added
- [#162]: `group_by` now accepts [function arguments](https://sq.io/docs/query/#group_by).
### Changed
- Renamed `groupby` to `group_by` to match jq.
- Renamed `orderby` to `order_by` to match jq.
## [v0.28.0] - 2023-03-26
### Added
- [#160]: Use `groupby()` to group results. See [query guide](https://sq.io/docs/query/#group_by).
## [v0.27.0] - 2023-03-25
### Added
- [#158]: Use `orderby()` to order results. See [query guide](https://sq.io/docs/query/#order_by).
## [v0.26.0] - 2023-03-22
### Added
- [#98]: Whitespace is now allowed in SLQ selector names. You can
do `@sakila | ."film actor" | ."actor id"`.
### Fixed
- [#155]: `sq inspect` now populates `schema` field in JSON for MySQL,
SQLite, and SQL Server (Postgres already worked).
## [v0.25.1] - 2023-03-19
### Fixed
- [#153]: Improved formatting of text table with long lines.
## [v0.25.0] - 2023-03-19
### Added
- [#15]: Column Aliases. You can now change specify an alias for a column (or column expression
such as a function). For example: `sq '.actor | .first_name:given_name`, or `sq .actor | count(*):quantity`.
- [#151]: `sq add` now has a `--active` flag, which immediately sets the new source
as the active source.
## [v0.24.4] - 2023-03-15
### Fixed
- Fixed typos in `sq sql` command help.
## [v0.24.3] - 2023-03-14
### Added
- When a CSV source has explicit column names (via `--opts cols=A,B,C`), `sq` now verifies
that the CSV data record field count matches the number of explicit columns.
## [v0.24.2] - 2023-03-13
### Fixed
- [#142]: Improved error handling when Postgres `current_schema()` is unavailable.
## [v0.24.1] - 2023-03-11
### Fixed
- [#144]: Handle corrupted config active source.
## [v0.24.0] - 2022-12-31
### Added
- `sq ping` now respects `--json` flag.
### Fixed
- Improved handling of file paths on Windows.
## [v0.23.0] - 2022-12-31
### Added
- `sq ls` now respects `--json` flag.
- `sq rm` now respects `--json` flag.
- `sq add` now respects `--json` flag.\`
- CI pipeline now verifies install packages after publish.
### Changed
- `sq rm` can delete multiple sources.
- `sq rm` doesn't print output unless `--verbose`.
- Redacted snipped is now `xxxxx` instead of `****`, to match stdlib `url.URL.Redacted()`.
### Fixed
- Fixed crash on Fedora systems (needed `--tags=netgo`).
## [v0.21.3] - 2022-12-30
### Added
- `sq version` respects `--json` flag.
- `sq version` respects `--verbose` flag.
- `sq version` shows `latest_version` info when `--verbose` and there's a newer version available.
### Changed
- `sq version` shows less info when `--verbose` is not set.
## [v0.20.0] - 2022-12-29
### Added
- `sq` now generates manpages (and installs them).
## [v0.19.0] - 2022-12-29
### Added
- Installer for [Arch Linux](https://archlinux.org),
via [Arch User Repository](https://aur.archlinux.org).
## [v0.18.2] - 2022-12-25
### Added
- The build pipeline now produces `.apk` packages for [Alpine Linux](https://www.alpinelinux.org),
and `install.sh` has been updated accordingly. However, the `.apk` files
are not yet published to a repository, so it's necessary to run `apk` against
the downloaded `.apk` file (`install.sh` does this for you).
## [v0.18.0] - 2022-12-24
### Added
- [#95]: `sq add` now has a `--password` (`-p`) flag that prompts the user for the data source
password, instead of putting it in the location string. It will also read from stdin
if there's input there.
## [v0.17.0] - 2022-12-23
### Changed
- More or less every `go.mod` dependency has been updated to latest. This includes
drivers for `sqlite` and `sqlserver`. The driver updates led to some broken
things, which have been fixed.
## [v0.16.1] - 2022-12-23
### Fixed
- [#123]: Shell completion is better behaved when a source is offline.
## [v0.16.0] - 2022-12-16
### Added
- `--verbose` flag is now global
- `install.sh` install script.
### Changed
- Improved GH workflow
- `sq inspect` shows less output by default (use `-v` to restore previous behavior)
### Fixed
- `sq inspect` can now deal with Postgres sources that have null values for constraint fields
## [v0.15.11] - 2022-11-06
### Changed
- Yet more changes to GitHub workflow.
## [v0.15.4] - 2021-09-18

### Changed
- [#91]: MySQL driver options no longer stripped
## [v0.15.2] - 2021-03-08
### Changed
