# 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). Breaking changes are annotated with ☢️, and alpha/beta features with 🐥. ## Upcoming This is a significant release, focused on improving i/o, responsiveness, and performance. The headline features are caching of ingested data for document sources such as CSV or Excel, and download caching for remote document sources. ### Added - Long-running operations (such as data ingestion, or file download) now result in a progress bar being displayed. Display of the progress bar is controlled by the new config options [`progress`](https://sq.io/docs/config#progress) and [`progress.delay`](https://sq.io/docs/config#progressdelay). You can also use the `--no-progress` flag to disable the progress bar. - Ingested [document sources](https://sq.io/docs/concepts#document-source) (such as [CSV](https://sq.io/docs/drivers/csv) or [Excel](https://sq.io/docs/drivers/xlsx)) now make use of an ingest cache DB. Previously, ingestion of document source data occurred on each `sq` command. It is now a one-time cost; subsequent use of the document source utilizes the cache DB. If the source document changes, the ingest cache DB is invalidated and ingested again. This is a significantly improved experience for large document sources. - There's several new commands to interact with the cache. - [`sq cache enable`](https://sq.io/docs/cmd/cache_enable) and [`sq cache disable`](https://sq.io/docs/cmd/cache_disable) control cache usage. You can also instead use the new [`ingest.cache`](https://sq.io/docs/config#ingestcache) config option. - [`sq cache clear`](https://sq.io/docs/cmd/cache_clear) clears the cache. - [`sq cache location`](https://sq.io/docs/cmd/cache_location) prints the cache location on disk. - [`sq cache stat`](https://sq.io/docs/cmd/cache_stat) shows stats about the cache. - [`sq cache tree`](https://sq.io/docs/cmd/cache_location) shows a tree view of the cache. - Downloading of remote document sources (e.g. a CSV file at [`https://sq.io/testdata/actor.csv`](https://sq.io/testdata/actor.csv)) has been completely overhauled. Previously, `sq` would re-download the remote file on every command. Now, the remote file is downloaded and cached locally. Subsequent commands check for staleness of the cached download, and re-download if necessary. - As part of the download revamp, new config options have been introduced: - [`http.request.timeout`](https://sq.io/docs/config#httprequesttimeout) is the timeout for the initial response from the server, and [`http.response.timeout`](https://sq.io/docs/config#httpresponsetimeout) is the timeout for reading the entire response body. We separate these two timeouts because it's possible that the server responds quickly, but then for a large file, the download takes too long. - [`https.insecure-skip-verify`](https://sq.io/docs/config#httpsinsecureskipverify) controls whether HTTPS connections verify the server's certificate. This is useful for remote files served with a self-signed certificate. - [`download.cache`](https://sq.io/docs/config#downloadcache) controls whether remote files are cached locally. - [`download.refresh.continue-on-error`](https://sq.io/docs/config#downloadrefreshcontinueonerror) controls whether `sq` should continue with a stale cached download if an error occurred while trying to refresh the download. This is a sort of "Airplane Mode" for remote document sources: `sq` continues with the cached download when the network is unavailable. - There are two more new config options introduced as part of the above work. - [`cache.lock.timeout`](https://sq.io/docs/config#cachelocktimeout) controls the time that `sq` will wait for a lock on the cache DB. The cache lock is introduced for when you have multiple `sq` commands running concurrently, and you want to avoid them stepping on each other. - Similarly, [`config.lock.timeout`](https://sq.io/docs/config#configlocktimeout) controls the timeout for acquiring the (newly-introduced) lock on `sq`'s config file. This helps prevent issues with multiple `sq` processes mutating the config concurrently. - `sq`'s own [logs](https://sq.io/docs/config#logging) previously outputted in JSON format. Now there's a new [`log.format`](https://sq.io/docs/config#logformat) config option that permits setting the log format to `json` or `text`. The `text` format is more human-friendly, and is now the default. ### Changed - Ingestion performance for [`json`](https://sq.io/docs/drivers/json#json) and [`jsonl`](https://sq.io/docs/drivers/json#jsonl) sources has been significantly improved. ### Fixed - Opening a DB connection now correctly honors [`conn.open-timeout`](https://sq.io/docs/config#connopen-timeout). ## [v0.46.1] - 2023-12-06 ### Fixed - `sq` sometimes failed to read from stdin if piped input was slow to arrive. This is now fixed. ## [v0.46.0] - 2023-11-22 ### Added - [#338]: While `sq` has had [`group_by`](https://sq.io/docs/query#group_by) for some time, somehow the [`having`](https://sq.io/docs/query#having) mechanism was never implemented. That's fixed. ```shell $ sq '.payment | .customer_id, sum(.amount) | group_by(.customer_id) | having(sum(.amount) > 200)' customer_id sum(.amount) 526 221.55 148 216.54 ``` - [#340]: The [`group_by`](https://sq.io/docs/query#group_by) function now has a synonym `gb`, and [`order_by`](https://sq.io/docs/query#order_by) now has synonym `ob`. These synonyms are experimental 🧪. The motivation is to reduce typing, especially the underscore (`_`) in both function names, but it's not clear that the loss of clarity is worth it. Maybe synonyms `group` and `order` might be better? Feedback welcome. ```shell # Previously $ sq '.payment | .customer_id, sum(.amount) | group_by(.customer_id) | order_by(.customer_id)' # Now $ sq '.payment | .customer_id, sum(.amount) | gb(.customer_id) | ob(.customer_id)' ``` - [#340]: [`sq inspect`](https://sq.io/docs/cmd/inspect): added flag shorthand `-C` for `--catalogs` and `-S` for `--schemata`. These were the only `inspect` flags without shorthand. ## [v0.45.0] - 2023-11-21 ### Changed - [#335]: Previously, `sq` didn't handle decimal values correctly. It basically shoved a decimal value into a `float` or `string` and hoped for the best. [As is known](https://medium.com/@mayuribudake999/difference-between-decimal-and-float-eede050f6c9a), floats are imprecise, and so we saw [unwanted behavior](https://github.com/neilotoole/sq/actions/runs/6932116521/job/18855333269#step:6:2345), e.g. ```shell db_type_test.go:194: Error Trace: D:/a/sq/sq/drivers/sqlite3/db_type_test.go:194 Error: Not equal: expected: "77.77" actual : "77.77000000000001" ``` Now, `sq` uses a dedicated [`Decimal`](https://github.com/shopspring/decimal) type end-to-end. No precision is lost, and at the output end, the value is rendered with the correct precision. There is a [proposal](https://github.com/golang/go/issues/30870) to add decimal support to the Go [`database/sql`](https://pkg.go.dev/database/sql) package. If that happens, `sq` will happily switch to that mechanism. - 👉 A side effect of decimal support is that some output formats may now render decimal values differently (i.e. correctly). In particular, Excel output should now render decimals as a number (as opposed to a string), and with the precision defined in the database. Previously, a database `NUMERIC(10,5)` value might have been rendered as `100.00`, but will now accurately render `100.00000`. ## [v0.44.0] - 2023-11-20 ### Added - New [SLQ](https://sq.io/docs/concepts#slq) function [`rownum()`](https://sq.io/docs/query#rownum) that returns the one-indexed row number of the current record. ```shell $ sq '.actor | rownum(), .actor_id, .first_name | order_by(.first_name)' rownum() actor_id first_name 1 71 ADAM 2 132 ADAM 3 165 AL ``` - [`sq inspect`](https://sq.io/docs/inspect) has two new flags: - [`--schemata`](https://sq.io/docs/inspect#schemata): list the source's schemas ```shell $ sq inspect @sakila/pg12 --schemata -y - schema: information_schema catalog: sakila owner: sakila - schema: public catalog: sakila owner: sakila active: true ``` - [`--catalogs`](https://sq.io/docs/inspect#catalogs): list the source's catalogs ```shell $ sq inspect @sakila/pg12 --catalogs CATALOG postgres sakila ``` ### Fixed - [`sq version`](https://sq.io/docs/cmd/version) now honors option [`format.datetime`](https://sq.io/docs/config#formatdatetime) when outputting build timestamp. - Fixed a fairly nasty bug that prevented correct rendering of SLQ functions nested inside an expression. ### Changed - The `--exec` and `--query` flags for [`sq sql`](https://sq.io/docs/cmd/sql) were removed in the preceding release ([v0.43.1]). That was probably a bit hasty, especially because it's possible those flags _could_ be reintroduced when the _query vs exec_ situation is figured out. So, those two flags are now restored, in that their use won't cause an error, but they've been hidden from command help, and remain no-op. ## [v0.43.1] - 2023-11-19 ### Added - Related to [#270], the output of [`sq inspect`](https://sq.io/docs/inspect) now includes the source's catalog (in JSON and YAML output formats). ### Fixed - MySQL driver didn't populate all expected values for [`sq inspect --overview`](https://sq.io/docs/inspect#source-overview). ### Changed - ☢️ Removed unused `--exec` and `--query` flags from [`sq sql`](https://sq.io/docs/cmd/sql) command. ## [v0.43.0] - 2023-11-18 ### Added - [#270]: Flag [`--src.schema`](https://sq.io/docs/cmd/sq/#override-active-schema) permits switching the source's schema (and catalog) for the duration of the command. The flag is supported for the [`sq`](https://sq.io/docs/cmd/sq#override-active-schema), [`sql`](https://sq.io/docs/cmd/sql/#active-source--schema) and [`inspect`](https://sq.io/docs/inspect#override-active-schema) commands. - New SLQ functions [`catalog()`](https://sq.io/docs/query#catalog) and [`schema()`](https://sq.io/docs/query#schema) return the catalog and schema of the DB connection. - The SLQ [`unique`](https://sq.io/docs/query#unique) function now has a synonym `uniq`. ### Changed - `sq src --text` now outputs only the handle of the active source. Previously it also printed the driver type and short location. Instead use `sq src --text --verbose` to see those details. ## [v0.42.1] - 2023-09-10 ### Fixed - [#308]: Fix to allow build on [32-bit systems](https://github.com/void-linux/void-packages/pull/45023). Thanks [@icp](https://github.com/icp1994). ## [v0.42.0] - 2023-08-22 ### Added - 🐥 [#279]: The SQLite [driver](https://sq.io/docs/drivers/sqlite) now has initial support for several SQLite [extensions](https://sq.io/docs/drivers/sqlite#extensions) baked in, including [Virtual Table](https://www.sqlite.org/vtab.html) and [FTS5](https://www.sqlite.org/fts5.html). Note that this is an early access release of extensions support. Please [open an issue](https://github.com/neilotoole/sq/issues/new/choose) if you discover something bad. ## [v0.41.1] - 2023-08-20 ### Fixed - `sq version` was missing a newline in its output. ## [v0.41.0] - 2023-08-20 This release is heavily focused on improvements to Microsoft Excel support. The underlying Excel library has been changed from [`tealeg/xlsx`](https://github.com/tealeg/xlsx) to [`qax-os/excelize`](https://github.com/qax-os/excelize), largely because `tealeg/xlsx` is no longer actively maintained. Thus, both the [XLSX output writer](https://sq.io/docs/output/#xlsx) and the [XLSX driver](https://sq.io/docs/drivers/xlsx) have been rewritten. There should be some performance improvements, but it's also possible that the rewrite introduced bugs. If you discover anything strange, please [open an issue](https://github.com/neilotoole/sq/issues/new/choose). ### Added - [#99]: The [CSV](https://sq.io/docs/drivers/csv) and [XLSX](https://sq.io/docs/drivers/xlsx) drivers can now handle duplicate header column names in the ingest data. For example, given a CSV file: ```csv actor_id,first_name,actor_id 1,PENELOPE,1 2,NICK,2 ``` The columns will be renamed to: ```csv actor_id,first_name,actor_id_1 ``` The renaming behavior is controlled by a new option [`ingest.column.rename`](https://sq.io/docs/config#ingestcolumnrename) This new option is effectively the ingest counterpart of the existing output option [`result.column.rename`](https://sq.io/docs/config#resultcolumnrename). - [#191]: The [XLSX](https://sq.io/docs/drivers/xlsx) driver now [detects](https://sq.io/docs/drivers/xlsx#header-row) header rows, like the CSV driver already does. Thus, you now typically don't need to specify the `--ingest.header` flag for Excel files. However, the option remains available in case `sq` can't figure it out for a particular file. - The Excel writer has three new config options for controlling date/time output. Note that these format strings are distinct from [`format.datetime`](https://sq.io/docs/config#formatdatetime) and friends, because Excel has its own format string mechanism. - [`format.excel.datetime`](https://sq.io/docs/config#formatexceldatetime): Controls datetime format, e.g. `2023-08-03 16:07:01`. - [`format.excel.date`](https://sq.io/docs/config#formatexceldatetime): Controls date-only format, e.g. `2023-08-03`. - [`format.excel.time`](https://sq.io/docs/config#formatexceldatetime): Controls time-only format, e.g. `4:07 pm`. - The ingest [kind detectors](https://sq.io/docs/detect#kinds) (e.g. for `CSV` or `XLSX`) now detect more [date & time formats](https://sq.io/docs/detect#datetime-formats) as `kind.Datetime`, `kind.Date`, and `kind.Time`. - If an error occurs when the output format is `text`, a stack trace is printed to `stderr` when the command is executed with `--verbose` (`-v`). - There's a new option [`error.format`](https://sq.io/docs/config#errorformat) that controls error output format independent of the main [`format`](https://sq.io/docs/config#format) option . The `error.format` value must be one of `text` or `json`. ### Changed - ☢️ The default Excel date format has changed. Previously the format was `11/9/89`, and now it is `1989-11-09`. The same applies to datetimes, e.g. `11/9/1989 00:00:00` becomes `1989-11-09 00:00`. This change is made to reduce ambiguity and confusion. `sq` uses a [library](https://github.com/qax-os/excelize) to interact with Excel files, and it seems that the library chooses a particular format by default (`11/9/89`). There are several paths we could take here: 1. Interrogate the OS, and use the OS locale date format. 2. Stick with the library default `11/9/89`. 3. Pick a default other than `11/9/89`. We pick the third option. The first option (locale-dependent) is excluded because, as a general rule, we want `sq` to produce the same output regardless of locale/system settings. We exclude the second option because month/day confuses most of the world. Thus, we're left with picking a default, and `1989-11-09` is the format used in [RFC3339](https://datatracker.ietf.org/doc/html/rfc3339) and friends. Whether this is the correct (standard?) approach is still unclear, and feedback is welcome. However, the user can make use of the new config options ([`format.excel.datetime`](https://sq.io/docs/config#formatexceldatetime) etc.) to customize the format as they see fit. - The XLSX writer now outputs header rows in **bold text**. - ☢️ The XLSX writer now outputs blob (`bytes`) cell data as a base64-encoded string, instead of raw bytes. ### Fixed - Fixed bug where source-specific config wasn't being propagated. ## [v0.40.0] - 2023-07-03 This release features a complete overhaul of the [`join`](https://sq.io/docs/query#joins) mechanism. ### Added - [#277]: A table selector can now have an alias. This in and of itself is not particularly useful, but it's a building block for [multiple joins](https://github.com/neilotoole/sq/issues/12). ```shell $ sq '@sakila | .actor:a | .a.first_name' ``` - New option `result.column.rename` that exposes a template used to rename result set column names before display. The primary use case is to de-duplicate columns names on a `SELECT * FROM tbl1 JOIN tbl2`, where `tbl1` and `tbl2` have clashing column names ([docs](https://sq.io/docs/config#resultcolumnrename)). - [#157]: Previously only `join` (`INNER JOIN`) was available: now the rest of the join types such as `left_outer_join`, `cross_join`, etc. are implemented ([docs](https://sq.io/docs/query#join-types)). ### Changed - ☢️ [#12]: The table [join](https://sq.io/docs/query#joins) mechanism has been completely overhauled. Now there's support for multiple joins. See [docs](https://sq.io/docs/query#joins). ```shell # Previously, only a single join was possible $ sq '.actor, .film_actor | join(.actor_id)' # Now, an arbitrary number of joins $ sq '.actor | join(.film_actor, .actor_id) | join(.film, .film_id)' ``` - ☢️ The alias for `--jsonl` (JSON Lines) has been changed to `-J`. ### Fixed - Config options weren't being propagated correctly to all parts of the code. ## [v0.39.1] - 2023-06-22 ### Fixed - Bug with `sq version` output on Windows. ## [v0.39.0] - 2023-06-22 ### Added - [#263]: `sq version` now supports `--yaml` output. - [#263]: `sq version` now outputs host OS details with `--verbose`, `--json` and `--yaml` flags. The motivation behind this is bug submission: we want to know which OS/arch the user is on. E.g. for `sq version -j`: ```json { "version": "v0.38.1", "commit": "eedc11ec46d1f0e78628158cc6fd58850601d701", "timestamp": "2023-06-21T11:41:34Z", "latest_version": "v0.39.0", "host": { "platform": "darwin", "arch": "arm64", "kernel": "Darwin", "kernel_version": "22.5.0", "variant": "macOS", "variant_version": "13.4" } } ``` - [#263]: The output of `sq inspect` and `sq inspect -v` has been refactored significantly, and should now be easier to work with ([docs](https://sq.io/docs/inspect)). ## [v0.38.1] - 2023-06-19 ### Fixed - [#261]: The JSON writer (`--json`) could get deadlocked when a record contained a large amount of data, triggering an internal `Flush()` (which is mutex-guarded) from within the mutex-guarded `WriteRecords()` method. ## [v0.38.0] - 2023-06-18 This release has significant improvements (and breaking changes) to SLQ (`sq`'s query language). ### Changed - ☢️ [#254]: The formerly-implicit "WHERE" mechanism now requires an explicit `where()` function. This, alas, is a fairly big breaking change. But it's necessary to remove an ambiguity roadblock. See discussion in the [issue](https://github.com/neilotoole/sq/issues/254). ```shell # Previously $ sq '.actor | .actor_id <= 2' # Now $ sq '.actor | where(.actor_id <= 2)' ``` - [#256]: Column-only queries are now possible. This has the neat side effect that `sq` can now be used as a calculator. ```shell $ sq 1+2 1+2 3 ``` You may want to use `--no-header` (`-H`) when using `sq` as a calculator. ```shell $ sq -H 1+2 3 $ sq -H '(1+2)*3' 9 ``` ### Fixed - Literals can now be selected ([docs](https://sq.io/docs/query#select-literal)). ```shell $ sq '.actor | .first_name, "X":middle_name, .last_name | .[0:2]' first_name middle_name last_name PENELOPE X GUINESS NICK X WAHLBERG ``` - Lots of expressions that previously failed badly, now work. ```shell $ sq '.actor | .first_name, (1+2):addition | .[0:2]' first_name addition PENELOPE 3 NICK 3 ``` - [#258]: Column aliases can now be arbitrary strings, instead of only a valid identifier. ```shell # Previously only valid identifier allowed $ sq '.actor | .first_name:given_name | .[0:2]' given_name PENELOPE NICK # Now, any arbitrary string can be used $ sq '.actor | .first_name:"Given Name" | .[0:2]' Given Name PENELOPE NICK ``` ## [v0.37.1] - 2023-06-15 ### Fixed - [#252]: Handle `*uint64` returned from DB. ## [v0.37.0] - 2023-06-13 ### Added - [#244]: Shell completion for `sq add LOCATION`. See [docs](https://sq.io/docs/source#location-completion). ## [v0.36.2] - 2023-05-27 ### Changed - ☢️ [Proprietary database functions](https://sq.io/docs/query#proprietary-functions) are now invoked by prefixing the function name with an underscore. For example: ```shell # 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`](https://sq.io/docs/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](https://sq.io/docs/output#csv-tsv) 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](https://sq.io/docs/output#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](https://sq.io/docs/config). 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: ```shell $ 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`](https://sq.io/docs/cmd/group) - [`sq ls`](https://sq.io/docs/cmd/ls) - [`sq mv`](https://sq.io/docs/cmd/mv) - [`sq rm`](https://sq.io/docs/cmd/rm) - [`sq src`](https://sq.io/docs/cmd/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. ```shell # 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. ```shell # 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`. ```shell # 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](https://sq.io/docs/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](https://sq.io/docs/source#groups). - `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: ```shell $ 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: ```shell $ 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](https://sq.io/docs/query#predefined-variables)): ```shell $ 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`](https://pkg.go.dev/golang.org/x/exp/slog) logging library. ## [v0.30.0] - 2023-03-27 ### 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"`. - ☢️ 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 - Bug fixes ## [v0.15.3] - 2021-03-13 ### Changed - [#91]: MySQL driver options no longer stripped ## [v0.15.2] - 2021-03-08 ### Changed - [#89]: Bug with SQL generated for joins.
