Changelog#

2.5.1#

  • Add exclude and include to thumbnail definitions to skip creation of thumbnails for some images. See Templates for more details.

2.5.0#

  • Add support for “shortcodes”, that is, function calls embedded in the document source. See Shortcodes for more details.

  • Add a new configuration option to load plugins from a directory. See Plugins for more details.

  • Documents which fail to parse don’t abort the build any more. Instead, a warning will be printed pointing to the broken document, and the processing will continue.

  • Markdown extensions can be configured now. See Configuration for more details. As part of this change, the default output format changed to html5 (previously it was xhtml.)

  • Add a new build_context global variable to templates. See Templates for more details.

2.4.1#

  • Add support for parallel node processing. This can result in significantly faster build times for sites with many resources. You can use --no-parallel to disable parallel processing in case this causes problems.

  • Add support for additional thumbnail formats. This also replaces the old mechanism using image_thumbnail_sizes with a new configuration setting, image_thumbnails. See Templates for more details.

  • Use tomllib on Python 3.11 instead of tomli.

  • The RedisCache uses transactions now to avoid problems with concurrent access to individual cache items.

2.4.0#

Note

This release contains breaking changes when using indices and collections. Make sure to review the changelog and the Collections and Indices pages when running into issues after updating.

The main change is that missing metadata fields in collections and indices result in an error now, instead of silently removing items. Use exclude_without to filter nodes missing specific metadata fields. When updating from < 2.4, you can simply copy the order_by/group_by entry in the respective YAML file into exclude_without to get the original behavior back.

  • Add Query.with_node_kinds and Query.without_node_kinds to Query. This allows lists of nodes (as returned by select() and other functions) to be filtered by the node kind. This is useful if you want to mix static content and documents in the same folder.

  • Add SiteTemplateProxy.select_pages and Page.children to select pages (i.e. document and index nodes) only without having to manually filter the result using with_node_kinds/without_node_kinds.

  • Add node_kinds to Collection.__init__ to allow constraining a collection to a specific node kind. See Collections for more details.

  • Add exclude_without to Collection.__init__ and Index.__init__ to allow excluding items without a specific metadata field.

  • Improve the debug output during publishing. The template publisher will now print which document is published using which template. As part of this change, Template.path was added.

  • Change how Page.references is populated for top level indices. Previously, references would not be populated for a top-level index. Additionally, improve the documentation of top-level indices, see Indices for more details.

  • Improve error handling when trying to sort nodes which are missing the corresponding metadata key, for example, using sorted_by_title(). Previously, this would raise an exception about a failed comparison involving None, now this raises a more useful exception which contains the path to the item missing the metadata key and which key was requested.

2.3.5#

  • Add --no-cache option to liara serve and liara build (off by default.)

    In some cases, it may be necessary to disable the cache to ensure up-to-date output during development. For instance SASS files can have includes which are not tracked by liara and fail to trigger a rebuild. With --no-cache each file is rebuilt on each request. This can be very slow and is thus only recommended during template/style development.

  • Improve the liara validate-links command:

    • Check internal links by default. Previously, if run without -t, no links were checked.

    • Return a non-zero exit code if broken links are found

    • Add more debug output

    • Fix an issue which prevented timeouts from being reported correctly.

2.3.4#

  • Add a new configuration option to select the SASS compiler. See configuration for details.

    Note

    The option is set to libsass by default for now, but it is highly recommended to install the command line compiler and use it. The option to use libsass will be removed in a future release.

  • Add support for caching to SassResourceNode. This can significantly speed up building sites with large amounts of SASS files.

  • Change the default log formatting settings:

    • The default output no longer includes the source. The source refers (typically) to the class producing the log message and results in noise for most normal use of Liara.

    • The verbose output includes the message severity now. This makes it easier to spot warnings and errors in the verbose output.

    • The debug output level contains both the source and the severity.

2.3.3#

  • Improve error handling during publishing. A generated node that fails to produce content is now skipped and a warning is printed.

  • Non-fatal issues (i.e. those which don’t stop the build) use the warning log level now instead of error.

  • Update PyYAML dependency to 6.0.

  • Update pymdown-extensions dependency to 9.0.

  • Replace toml dependency with tomli which is TOML 1.0 compliant (toml only supports TOML 0.5)

  • Add Python 3.10 as an officially supported version.

2.3.2#

  • Add a new --date option to the command line to build the site at a different date. This is useful conjunction with the DateFilter, as it allows previewing scheduled entries.

  • Improve error handling during content discovery. An error while creating a document will no longer abort the build. Additionally, instead of printing a full stack trace, an short error message containing the file path is printed. In any case, discovery continues so multiple broken documents can be identified.

2.3.1#

  • Improve ambiguous template pattern resolution. See Templates for details.

  • Allow setting template backend options. See Templates for details. As part of this change, the Jinja2 backend now sets trim_blocks and lstrip_blocks by default to True.

2.3.0#

  • Add a --port option to liara serve to change the listen port.

  • Add an ignore_files option to ignore certain file patterns. This is particularly useful if an editor creates lock or backup files that should be ignored. See Configuration for details.

  • The file discovery process will ignore invalid index and resource files instead of failing with an exception. An error will be logged to help find the problematic files.

  • Fix liara list-content not showing the node type on _index nodes.

  • Handling of metadata has changed:

    • Document metadata can be placed in a separate .meta file instead of being part of the document itself. See Content for details.

    • Separate .meta files for metadata are no longer supported in the static and resource directory. This previously didn’t work as expected – resource files with .meta files associated had the .meta file processed (which would cause a failure), and static files had the .meta file added as a separate static file. From this release on, .meta files don’t get any special treatment when placed in the static or resource directory trees. Static files inside the content directory continue to support metadata files. See Content for details.

2.2.1#

  • Mako is now installed by default, and the mako extra is gone. If you installed Liara using liara[mako], please switch to liara going forward.

  • liara.template.Page.content now returns an empty string for IndexNode instances. Previously, it would raise an exception.

  • liara quickstart gained a new option, --template-backend, which allows selecting between jinja2 and mako templates.

  • The collection sort order can be reversed now. See Collections for details.

2.2.0#

  • Bump minimal required Python version to 3.8.

  • liara serve now uses the cache configuration specified by the user instead of always using a filesystem cache with fixed paths.

  • Add RedisCache, which uses Redis as the storage backend. Using Redis in a shared environment allows multiple clients to benefit from the cache. Additionally, the Redis cache allows for cache entries to expire, so it won’t accumulate garbage over time (i.e. draft posts which never get published, etc.) See Configuration for details on how to enable Redis. Redis also requires Liara to be installed with the [redis] option.

2.1.3#

  • Fix liara quickstart not working.

  • Fix a bug when fixing up timezones while using the zoneinfo package for timezone data.

2.1.2#

  • Deprecate liara.template.Page.meta in favor of liara.template.Page.metadata (which was newly added in this version) for consistency with liara.template.SiteTemplateProxy.metadata.

  • Use the logger in liara serve instead of printing directly to the console for log messages. The default listen URL will be still printed if showing the browser is disabled.

  • Set the Content-Type header in liara serve. This fixes an issue with Chrome/Edge where SVG images would not work as they were served without a content type.

  • Update jinja2 dependency to 3.0. This provides access to new Jinja2 features like required blocks.

  • Update click dependency to 8.0.

2.1.1#

  • Fix plugins not being packaged.

2.1.0#

  • Introduce a new plugin system. This moves the has-pending-document command into a new plugin and adds signals to interact with Liara’s processing. See Plugins for details.

  • Remove liara.version.version. Use the standard liara.__version__ variable instead, which was already present in earlier versions.

2.0.7#

  • Add a server_rule_only option to prevent the creation of redirection nodes and use the redirection paths verbatim.

2.0.6#

  • Add has-pending-document to the command line. This will check if there is any content which is filtered by the DateFilter. This is useful for cron-based deploys which try to not rebuild if there are no content changes, as there is no other way to find out if all content in a given revision has been published.

2.0.5#

  • Fix liara create-config not working.

2.0.4#

  • Add Sqlite3Cache, which allows caching everything into a single file instead of one file per entry.

  • Add a bytecode cache for the Jinja2TemplateRepository.

  • Fix generated nodes not getting generated when using liara serve.

  • Reduce debug spew when stopping liara serve using ^C.

2.0.3#

2.0.2#

  • Fix a packaging issue.

2.0.1#

  • Improve document handling: Documents without a trailing newline are now supported, previously they would cause an error.

  • Improve configuration: Empty configuration files are now supported.

  • Fix list-files requiring a type to be specified.

  • Add exclude().

  • Override base_url when serving locally. This was previously documented to work, but not implemented. As part of this change, set_metadata_item() was added.

2.0#

liara 2.0 is a complete rewrite of liara, with no shared code with the 1.x series. liara 2 is now template & content driven, and no longer just a library which simplifies static page generation. Unlike the 1.x series, it is possible to use liara 2 without writing any Python code.
