See also the annotated release notes for this release.

• Documentation now uses the Furo Sphinx theme. (#435)
• Code examples in documentation now have a "copy to clipboard" button. (#436)
• sqlite_utils.utils.utils.rows_from_file() is now a documented API, see Reading rows from a file. (#443)
• rows_from_file() has two new parameters to help handle CSV files with rows that contain more values than are listed in that CSV file's headings: ignore_extras=True and extras_key="name-of-key". (#440)
• sqlite_utils.utils.maximize_csv_field_size_limit() helper function for increasing the field size limit for reading CSV files to its maximum, see Setting the maximum CSV field size limit. (#442)
• table.search(where=, where_args=) parameters for adding additional WHERE clauses to a search query. The where= parameter is available on table.search_sql(...) as well. See Searching with table.search(). (#441)
• Fixed bug where table.detect_fts() and other search-related functions could fail if two FTS-enabled tables had names that were prefixes of each other. (#434)

• Datasette now runs some SQL queries in parallel. This has limited impact on performance, see this research issue for details.
• Datasette should now be compatible with Pyodide. (#1733)
• datasette publish cloudrun has a new --timeout option which can be used to increase the time limit applied by the Google Cloud build environment. Thanks, Tim Sherratt. (#1717)
• Spaces in database names are now encoded as + rather than ~20. (#1701)
• <Binary: 2427344 bytes> is now displayed as <Binary: 2,427,344 bytes> and is accompanied by tooltip showing "2.3MB". (#1712)
• Don't show the facet option in the cog menu if faceting is not allowed. (#1683)
• Code examples in the documentation are now all formatted using Black. (#1718)
• Request.fake() method is now documented, see Request object.

• Now depends on click-default-group-wheel, a pure Python wheel package. This means you can install and use this package with Pyodide, which can run Python entirely in your browser using WebAssembly. (#429)

Try that out using the Pyodide REPL:

```pycon

import micropip await micropip.install("sqlite-utils") import sqlite_utils db = sqlite_utils.Database(memory=True) list(db.query("select 3 * 5")) [{'3 * 5': 15}] ```

• New errors=r.IGNORE/r.SET_NULL parameter for the r.parsedatetime() and r.parsedate() convert recipes. (#416)
• Fixed a bug where --multi could not be used in combination with --dry-run for the convert command. (#415)
• New documentation: Using a convert() function to execute initialization. (#420)
• More robust detection for whether or not deterministic=True is supported. (#425)

• Fixed a bug where databases with a different route from their name (as used by the datasette-hashed-urls plugin) returned errors when executing custom SQL queries. (#1682)

In preparation for Datasette 1.0, this release includes two potentially backwards-incompatible changes. Hashed URL mode has been moved to a separate plugin, and the way Datasette generates URLs to databases and tables with special characters in their name such as / and . has changed.

Datasette also now requires Python 3.7 or higher.

See also the annotated release notes.

• URLs within Datasette now use a different encoding scheme for tables or databases that include "special" characters outside of the range of a-zA-Z0-9_-. This scheme is explained here: Tilde encoding. (#1657)
• Removed hashed URL mode from Datasette. The new datasette-hashed-urls plugin can be used to achieve the same result, see datasette-hashed-urls for details. (#1661)
• Databases can now have a custom path within the Datasette instance that is independent of the database name, using the db.route property. (#1668)
• Datasette is now covered by a Code of Conduct. (#1654)
• Python 3.6 is no longer supported. (#1577)
• Tests now run against Python 3.11-dev. (#1621)
• New datasette.ensure_permissions(actor, permissions) internal method for checking multiple permissions at once. (#1675)
• New datasette.check_visibility(actor, action, resource=None) internal method for checking if a user can see a resource that would otherwise be invisible to unauthenticated users. (#1678)
• Table and row HTML pages now include a <link rel="alternate" type="application/json+datasette" href="..."> element and return a Link: URL; rel="alternate"; type="application/json+datasette" HTTP header pointing to the JSON version of those pages. (#1533)
• Access-Control-Expose-Headers: Link is now added to the CORS headers, allowing remote JavaScript to access that header.

• Common Datasette symbols can now be imported directly from the top-level datasette package, see Import shortcuts. Those symbols are Response, Forbidden, NotFound, hookimpl, actor_matches_allow. (#957)
• /-/versions page now returns additional details for libraries used by SpatiaLite. (#1607)
• Documentation now links to the Datasette Tutorials.
• Datasette will now also look for SpatiaLite in /opt/homebrew - thanks, Dan Peterson. (#1649)

Plugins and internals

• New plugin hook: filters_from_request(request, database, table, datasette), which runs on the table page and can be used to support new custom query string parameters that modify the SQL query. (#473)
• Added two additional methods for writing to the database: await db.execute_write_script(sql, block=True) and await db.execute_write_many(sql, params_seq, block=True). (#1570)
• The db.execute_write() internal method now defaults to blocking until the write operation has completed. Previously it defaulted to queuing the write and then continuing to run code while the write was in the queue. (#1579)
• Database write connections now execute the prepare_connection(conn, database, datasette) plugin hook. (#1564)
• The Datasette() constructor no longer requires the files= argument, and is now documented at Datasette class. (#1563)
• The tracing feature now traces write queries, not just read queries. (#1568)
• The query string variables exposed by request.args will now include blank strings for arguments such as foo in ?foo=&bar=1 rather than ignoring those parameters entirely. (#1551)

Faceting

• The number of unique values in a facet is now always displayed. Previously it was only displayed if the user specified ?_facet_size=max. (#1556)
• Facets of type date or array can now be configured in metadata.json, see Facets in metadata.json. Thanks, David Larlet. (#1552)
• New ?_nosuggest=1 parameter for table views, which disables facet suggestion. (#1557)
• Fixed bug where ?_facet_array=tags&_facet=tags would only display one of the two selected facets. (#625)

Other small fixes

• Label columns detected for foreign keys are now case-insensitive, so Name or TITLE will be detected in the same way as name or title. (#1544)
• Upgraded Pluggy dependency to 1.0. (#1575)
• Now using Plausible analytics for the Datasette documentation.
• explain query plan is now allowed with varying amounts of whitespace in the query. (#1588)

• Fixed bug where writable canned queries could not be used with custom templates. (#1547)
• Improved fix for a bug where columns with a underscore prefix could result in unnecessary hidden form fields. (#1527)

• New CLI reference documentation page, listing the output of --help for every one of the CLI commands. (#383)
• sqlite-utils rows now has --limit and --offset options for paginating through data. (#381)
• sqlite-utils rows now has --where and -p options for filtering the table using a WHERE query, see Returning all rows in a table. (#382)

CLI and Python library improvements to help run ANALYZE after creating indexes or inserting rows, to gain better performance from the SQLite query planner when it runs against indexes.

Three new CLI commands: create-database, analyze and bulk.

More details and examples can be found in the annotated release notes.

• The CLI tool can now also be run using python -m sqlite_utils. (#368)
• Using --fmt now implies --table, so you don't need to pass both options. (#374)
• The --convert function applied to rows can now modify the row in place. (#371)
• The insert-files command supports two new columns: stem and suffix. (#372)
• The --nl import option now ignores blank lines in the input. (#376)

• The table.lookup() method now has an optional second argument which can be used to populate columns only the first time the record is created, see Working with lookup tables. (#339)
• sqlite-utils memory now has a --flatten option for flattening nested JSON objects into separate columns, consistent with sqlite-utils insert. (#332)
• table.create_index(..., find_unique_name=True) parameter, which finds an available name for the created index even if the default name has already been taken. This means that index-foreign-keys will work even if one of the indexes it tries to create clashes with an existing index name. (#335)
• Added py.typed to the module, so mypy should now correctly pick up the type annotations. Thanks, Andreas Longo. (#331)
• Now depends on python-dateutil instead of depending on dateutils. Thanks, Denys Pavlov. (#324)
• table.create() (see Explicitly creating a table) now handles dict, list and tuple types, mapping them to TEXT columns in SQLite so that they can be stored encoded as JSON. (#338)
• Inserted data with square braces in the column names (for example a CSV file containing a item[price]) column now have the braces converted to underscores: item_price_. Previously such columns would be rejected with an error. (#329)

This release introduces the new sqlite-utils convert command (#251) and corresponding table.convert(...) Python method (#302). These tools can be used to apply a Python conversion function to one or more columns of a table, either updating the column in place or using transformed data from that column to populate one or more other columns.

This command-line example uses the Python standard library textwrap module to wrap the content of the content column in the articles table to 100 characters: $ sqlite-utils convert content.db articles content\ '"\n".join(textwrap.wrap(value, 100))'\ --import=textwrap The same operation in Python code looks like this: ```python import sqlite_utils, textwrap

db = sqlite_utils.Database("content.db") db["articles"].convert("content", lambda v: "\n".join(textwrap.wrap(v, 100))) ``` See the full documentation for the sqlite-utils convert command and the table.convert(...) Python method for more details.

Also in this release:

• The new table.count_where(...) method, for counting rows in a table that match a specific SQL WHERE clause. (#305)
• New --silent option for the sqlite-utils insert-files command to hide the terminal progress bar, consistent with the --silent option for sqlite-utils convert. (#301)

• sqlite-utils schema my.db table1 table2 command now accepts optional table names. (#299)
• sqlite-utils memory --help now describes the --schema option.

• Fix for an intermittent race condition caused by the refresh_schemas() internal function. (#1231)

• New datasette --uds /tmp/datasette.sock option for binding Datasette to a Unix domain socket, see proxy documentation. (#1388)
• "searchmode": "raw" table metadata option for defaulting a table to executing SQLite full-text search syntax without first escaping it, see Advanced SQLite search queries. (#1389)
• New plugin hook: get_metadata(datasette, key, database, table), for returning custom metadata for an instance, database or table. Thanks, Brandon Roberts! (#1384)

• This project now uses flake8 and has started to use mypy. (#291)
• New documentation on contributing to this project. (#292)

• New plugin hook: skip_csrf(datasette, scope), for opting out of CSRF protection based on the incoming request. (#1377)
• POST requests to endpoints that do not support that HTTP verb now return a 405 error.
• db.path can now be provided as a pathlib.Path object, useful when writing unit tests for plugins. Thanks, Chris Amico. (#1365)

• New sqlite-utils memory data.csv --schema option, for outputting the schema of the in-memory database generated from one or more files. See --schema, --dump and --save. (#288)
• Added installation instructions. (#286)

This release introduces the sqlite-utils memory command, which can be used to load CSV or JSON data into a temporary in-memory database and run SQL queries (including joins across multiple files) directly against that data.

Also new: sqlite-utils insert --detect-types, sqlite-utils dump, table.use_rowid plus some smaller fixes.

sqlite-utils memory

This example of sqlite-utils memory retrieves information about the all of the repositories in the Dogsheep organization on GitHub using this JSON API, sorts them by their number of stars and outputs a table of the top five (using -t):

``` $ curl -s 'https://api.github.com/users/dogsheep/repos'\ | sqlite-utils memory - ' select full_name, forks_count, stargazers_count from stdin order by stargazers_count desc limit 5 ' -t full_name forks_count stargazers_count

dogsheep/twitter-to-sqlite 12 225 dogsheep/github-to-sqlite 14 139 dogsheep/dogsheep-photos 5 116 dogsheep/dogsheep.github.io 7 90 dogsheep/healthkit-to-sqlite 4 85 ```

The tool works against files on disk as well. This example joins data from two CSV files:

$ cat creatures.csv species_id,name 1,Cleo 2,Bants 2,Dori 2,Azi $ cat species.csv id,species_name 1,Dog 2,Chicken $ sqlite-utils memory species.csv creatures.csv ' select * from creatures join species on creatures.species_id = species.id ' [{"species_id": 1, "name": "Cleo", "id": 1, "species_name": "Dog"}, {"species_id": 2, "name": "Bants", "id": 2, "species_name": "Chicken"}, {"species_id": 2, "name": "Dori", "id": 2, "species_name": "Chicken"}, {"species_id": 2, "name": "Azi", "id": 2, "species_name": "Chicken"}]

Here the species.csv file becomes the species table, the creatures.csv file becomes the creatures table and the output is JSON, the default output format.

You can also use the --attach option to attach existing SQLite database files to the in-memory database, in order to join data from CSV or JSON directly against your existing tables.

Full documentation of this new feature is available in Querying data directly using an in-memory database. (#272)

sqlite-utils insert --detect-types

The sqlite-utils insert command can be used to insert data from JSON, CSV or TSV files into a SQLite database file. The new --detect-types option (shortcut -d), when used in conjunction with a CSV or TSV import, will automatically detect if columns in the file are integers or floating point numbers as opposed to treating everything as a text column and create the new table with the corresponding schema. See Inserting CSV or TSV data for details. (#282)

The two big new features in this release are the _internal SQLite in-memory database storing details of all connected databases and tables, and support for JavaScript modules in plugins and additional scripts.

For additional commentary on this release, see Datasette 0.54, the annotated release notes.

The _internal database

As part of ongoing work to help Datasette handle much larger numbers of connected databases and tables (see Datasette Library) Datasette now maintains an in-memory SQLite database with details of all of the attached databases, tables, columns, indexes and foreign keys. (#1150)

This will support future improvements such as a searchable, paginated homepage of all available tables.

You can explore an example of this database by signing in as root to the latest.datasette.io demo instance and then navigating to latest.datasette.io/_internal.

Plugins can use these tables to introspect attached data in an efficient way. Plugin authors should note that this is not yet considered a stable interface, so any plugins that use this may need to make changes prior to Datasette 1.0 if the _internal table schemas change.

Named in-memory database support

As part of the work building the _internal database, Datasette now supports named in-memory databases that can be shared across multiple connections. This allows plugins to create in-memory databases which will persist data for the lifetime of the Datasette server process. (#1151)

The new memory_name= parameter to the Database class can be used to create named, shared in-memory databases.

JavaScript modules

JavaScript modules were introduced in ECMAScript 2015 and provide native browser support for the import and export keywords.

To use modules, JavaScript needs to be included in <script> tags with a type="module" attribute.

Datasette now has the ability to output <script type="module"> in places where you may wish to take advantage of modules. The extra_js_urls option described in Custom CSS and JavaScript can now be used with modules, and module support is also available for the extra_body_script() plugin hook. (#1186, #1187)

datasette-leaflet-freedraw is the first example of a Datasette plugin that takes advantage of the new support for JavaScript modules. See Drawing shapes on a map to query a SpatiaLite database for more on this plugin.

Code formatting with Black and Prettier

Datasette adopted Black for opinionated Python code formatting in June 2019. Datasette now also embraces Prettier for JavaScript formatting, which like Black is enforced by tests in continuous integration. Instructions for using these two tools can be found in the new section on Code formatting in the contributors documentation. (#1167)

This release includes a number of changes relating to an internal rebranding effort: Datasette's configuration mechanism (things like datasette --config default_page_size:10) has been renamed to settings.

• New --setting default_page_size 10 option as a replacement for --config default_page_size:10 (note the lack of a colon). The --config option is deprecated but will continue working until Datasette 1.0. (#992)
• The /-/config introspection page is now /-/settings, and the previous page redirects to the new one. (#1103)
• The config.json file in Configuration directory mode is now called settings.json. (#1104)
• The undocumented datasette.config() internal method has been replaced by a documented .setting(key) method. (#1107)

Also in this release:

• New plugin hook: database_actions(datasette, actor, database), which adds menu items to a new cog menu shown at the top of the database page. (#1077)
• datasette publish cloudrun has a new --apt-get-install option that can be used to install additional Ubuntu packages as part of the deployment. This is useful for deploying the new datasette-ripgrep plugin. (#1110)

• Fixed bug where row pages could sometimes 500 if the underlying queries exceeded a time limit. (#1088)
• Fixed a bug where the table action menu could appear partially obscured by the edge of the page. (#1084)

This release introduces a new sqlite-utils search command for searching tables, see Executing searches. (#192)

The table.search() method has been redesigned, see Searching with table.search(). (#197)

The release includes minor backwards-incompatible changes, hence the version bump to 3.0. Those changes, which should not affect most users, are:

• The -c shortcut option for outputting CSV is no longer available. The full --csv option is required instead.
• The -f shortcut for --fmt has also been removed - use --fmt.
• The table.search() method now defaults to sorting by relevance, not sorting by rowid. (#198)
• The table.search() method now returns a generator over a list of Python dictionaries. It previously returned a list of tuples.

Also in this release:

• The query, tables, rows and search CLI commands now accept a new --tsv option which outputs the results in TSV. (#193)
• A new table.virtual_table_using property reveals if a table is a virtual table, and returns the upper case type of virtual table (e.g. FTS4 or FTS5) if it is. It returns None if the table is not a virtual table. (#196)
• The new table.search_sql() method returns the SQL for searching a table, see Building SQL queries with table.search_sql().
• sqlite-utils rows now accepts multiple optional -c parameters specifying the columns to return. (#200)

Changes since the 3.0a0 alpha release:

• The sqlite-utils search command now defaults to returning every result, unless you add a --limit 20 option.
• The sqlite-utils search -c and table.search(columns=[]) options are now fully respected. (#201)

This release introduces a new sqlite-utils search command for searching tables, see Executing searches. (#192)

The table.search() method has been redesigned, see Searching with table.search(). (#197)

The release includes minor backwards-incompatible changes, hence the version bump to 3.0. Those changes, which should not affect most users, are:

• The -c shortcut option for outputting CSV is no longer available. The full --csv option is required instead.

• The new table.search_sql() method returns the SQL for searching a table, see Building SQL queries with table.search_sql().
• sqlite-utils rows now accepts multiple optional -c parameters specifying the columns to return. (#200)

• Improvements to the new Binary data documentation page.

A new visual design, plugin hooks for adding navigation options, better handling of binary data, URL building utility methods and better support for running Datasette behind a proxy.

New visual design

Datasette is no longer white and grey with blue and purple links! Natalie Downe has been working on a visual refresh, the first iteration of which is included in this release. (#1056)

Plugins can now add links within Datasette

A number of existing Datasette plugins add new pages to the Datasette interface, providig tools for things like uploading CSVs, editing table schemas or configuring full-text search.

Plugins like this can now link to themselves from other parts of Datasette interface. The menu_links(datasette, actor) hook (#1064) lets plugins add links to Datasette's new top-right application menu, and the table_actions(datasette, actor, database, table) hook (#1066) adds links to a new "table actions" menu on the table page.

The demo at latest.datasette.io now includes some example plugins. To see the new table actions menu first sign into that demo as root and then visit the facetable table to see the new cog icon menu at the top of the page.

Binary data

SQLite tables can contain binary data in BLOB columns. Datasette now provides links for users to download this data directly from Datasette, and uses those links to make binary data available from CSV exports. See Binary data for more details. (#1036 and #1034).

URL building

The new datasette.urls family of methods can be used to generate URLs to key pages within the Datasette interface, both within custom templates and Datasette plugins. See Building URLs within plugins for more details. (#904)

Running Datasette behind a proxy

The base_url configuration option is designed to help run Datasette on a specific path behind a proxy - for example if you want to run an instance of Datasette at /my-datasette/ within your existing site's URL hierarchy, proxied behind nginx or Apache.

Support for this configuration option has been greatly improved (#1023), and guidelines for using it are now available in a new documentation section on Running Datasette behind a proxy. (#1027)
