CHANGELOG

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Breaking changes are annotated with ☢️.

v0.37.0 - 2023-06-13

Added

• #244: Shell completion for sq add LOCATION. See docs.

v0.36.2 - 2023-05-27

Changed

• ☢️ Proprietary database functions are now invoked by prefixing the function name with an underscore. For example:

  # mysql "date_format" func
  $ sq '@sakila/mysql | .payment | _date_format(.payment_date, "%m")'
  
  # Postgres "date_trunc" func
  $ sq '@sakila/postgres | .payment | _date_trunc("month", .payment_date)'
  

v0.36.1 - 2023-05-26

Fixed

• sq diff: Renamed --count flag to --counts as intended.

v0.36.0 - 2023-05-25

The major feature is the long-gestating sq diff.

Added

• #229: sq diff compares two sources, or tables.
• sq inspect --dbprops is a new mode that returns only the DB properties. Relatedly, the properties mechanism is now implemented for all four supported DB types (previously, it was only implemented for Postgres and MySQL).
• CSV format now colorizes output.

Changed

• sq inspect -v previously returned DB properties in a field named db_variables. This field has been renamed to db_properties. The renaming reflects the fact that some of those properties aren't really variables in the sense that they can be modified (e.g. DB server version or such).
• The structure of the former db_variables (now db_properties) field has changed. Previously it was an array of {"name": "XX", "value": "YY"} values, but now is a map, where the keys are strings, and the values can be either a scalar (bool, int, string, etc.), or a nested value such as an array or map. This change is made because some databases (e.g. SQLite) feature complex data in some property values.
• CSV format now renders byte sequences as [777 bytes] instead of dumping the raw bytes.
• ☢️ TSV format (--tsv) no longer has a shorthand form -T. Apparently that shorthand wasn't used much, and -T is needed elsewhere.
• ☢️ Likewise, --xml no longer has shorthand -X. And --markdown has lost alias --md.
• In addition to the format flags --text, --json, etc., there is now a --format=FORMAT flag, e.g. --format=json. This will allow sq to continue to expand the number of output formats, without needing to have a dedicated flag for each format.

Fixed

• sq config edit @source was failing to save any edits.

v0.35.0 - 2023-05-10

Added

• #8: Results can now be output in YAML.

Fixed

• sq config get OPT --text now prints only the value, not KEY VALUE. If you want to see key and value, consider using --yaml, or --text --verbose.

v0.34.2 - 2023-05-08

Fixed

• Both --markdown and the alias --md are now supported.

v0.34.1 - 2023-05-07

Fixed

• Fixed a minor issue where sq ls -jv and sq ls -yv produced no output if config contained no explicitly set options.

v0.34.0 - 2023-05-07

This release significantly overhauls sq's config mechanism (#199). For an overview, see the new config docs.

Alas, this release has several minor breaking changes ☢️.

Added

• sq config ls shows config.
• sq config get gets individual config option.
• sq config set sets config values.
• sq config edit edits config.
  • Editor can be specified via $EDITOR or $SQ_EDITOR.
• sq config location prints the location of the config dir.
• --config flag is now honored globally.
• Many more knobs are exposed in config.
• Logging is much more configurable. There are new knobs:

  $ sq config set log true
  $ sq config set log.level INFO
  $ sq config set log.file /var/log/sq.log
  

  There are also equivalent flags (--log, --log.file and --log.level) and envars (SQ_LOG, SQ_LOG_FILE and SQ_LOG_LEVEL).
• Several more commands support YAML output:
  • sq group
  • sq ls
  • sq mv
  • sq rm
  • sq src

Changed

• The structure of sq's config file (sq.yml) has changed. The config file is automatically upgraded when using the new version.
• The default location of the sq log file has changed. The new location is platform-dependent. Use sq config get log.file -v to view the location, or sq config set log.file /path/to/sq.log to set it.
• ☢️ Envar SQ_CONFIG replaces SQ_CONFIGDIR.
• ☢️ Envar SQ_LOG_FILE replaces SQ_LOGFILE.
• ☢️ Format flag --table is renamed to --text. This is changed because while the output is mostly in table format, sometimes it's just plain text. Thus table was not quite accurate.
• ☢️ The flag to explicitly specify a driver when piping input to sq has been renamed from --driver to --ingest.driver. This change aligns the naming of the ingest options and reduces ambiguity.

  # previously
  $ cat mystery.data | sq --driver=csv '.data'
  
  # now
  $ cat mystery.data | sq --ingest.driver=csv '.data'
  

• ☢️ sq add no longer has the generic --opts x=y mechanism. This flag was ambiguous and confusing. Instead, use explicit option flags.

  # previously
  $ sq add ./actor.csv --opts=header=false
  
  # now
  $ sq add ./actor.csv --ingest.header=false
  

• ☢️ The short form of the sq add --handle flag has been changed from -h to -n. While this is not ideal, the -h shorthand is already in use everywhere else as the short form of --header.

  # previously
  $ sq add ./actor.csv -h @actor
  
  # now
  $ sq add ./actor.csv -n @actor
  

• ☢️ The --pretty flag has been removed. Its only previous use was with the json format, where if --pretty=false would output the JSON in compact form. To better align with jq, there is now a --compact / -c flag that behaves identically to jq.
• ☢️ Because of the above --compact / -c flag, the short form of the --csv flag is changing from -c to -C. It's an unfortunate situation, but alignment with jq's behavior is an overarching principle that justifies the change.

v0.33.0 - 2023-04-15

The headline feature is source groups. This is the biggest change to the sq CLI in some time, and should make working with lots of sources much easier.

Added

• #192: sq now has a mechanism to group sources. A source handle can now be scoped. For example, instead of @sakila_prod, @sakila_staging, etc, you can use @prod/sakila, @staging/sakila. Use sq group prod to set the active group (which sq ls respects). See docs.
• sq group GROUP sets the active group to GROUP.
• sq group returns the active group (default is /, the root group).
• sq ls GROUP lists the sources in GROUP.
• sq ls --group (or sq ls -g) lists all groups.
• sq mv moves/renames sources and groups.

Changed

• sq ls now shows the active item in a distinct color. It no longer adds an asterisk to the active item.
• sq ls now sorts alphabetically when using --table format.
• sq ls now shows the sources in the active group only. But note that the default active group is / (the root group), so the default behavior of sq ls is the same as before.
• sq add hello.csv will now generate the handle @hello instead of @hello_csv. On a second invocation, it will return @hello1 instead of @hello_csv_1. Why this change? Well, with the availability of the source group mechanism, the _ character in the handle somehow looked ugly. And more importantly, _ is a relative pain to type.
• sq ping has changed to support groups. Instead of sq ping --all, you can do sq ping GROUP, e.g. sq ping /.

v0.32.0 - 2023-04-09

Added

• #187: For csv sources, sq will now try to auto-detect if the CSV file has a header row or not. Previously, this needed to be explicitly specified via an awkward syntax:

  $ sq add ./actor.csv --opts=header=true
  

  This change makes working with CSV files significantly lower friction. A command like the below now almost always works as expected:

  $ cat ./actor.csv | sq .data
  

  Support for Excel/XLSX header detection is in #191.

Fixed

• sq is now better at detecting the (data) kind of CSV fields. It now more accurately distinguishes between Decimal and Int, and knows how to handle Datetime.

• #189: sq now treats CSV empty fields as NULL.

v0.31.0 - 2023-03-08

Added

• #173: Predefined variables via --arg flag (docs):

  $ sq --arg first TOM '.actor | .first_name == $first'
  

Changes

• Use --md instead of --markdown for outputting Markdown.

Fixed

• #185: sq inspect now better handles "too many connections" situations.
• go.mod: Moved to jackc/pgx v5.
• Refactor: switched to slog logging library.

v0.30.0 - 2023-03-27

Added

• #164: Implemented unique function (docs):

  $ sq '.actor | .first_name | unique'
  

  This is equivalent to:

  SELECT DISTINCT first_name FROM actor
  

• Implemented count_unique function (docs).

  $ sq '.actor | count_unique(.first_name)'
  

Changed

• The count function has been changed (docs)
  • Added no-args version: .actor | count equivalent to SELECT COUNT(*) AS "count" FROM "actor".
  • ☢️ 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.

  # 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.

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.

v0.27.0 - 2023-03-25

Added

• #158: Use orderby() to order results. See query guide.

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

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, via Arch User Repository.

v0.18.2 - 2022-12-25

Added

• The build pipeline now produces .apk packages for Alpine Linux, 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

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
