tarchetypes 0.10.0.9002

• Add an output_file argument to tar_quarto() and tar_quarto_raw() for single documents (#198, @mutlusun).
• Detect child quarto documents (#199, @mutlusun).

tarchetypes 0.10.0 (2024-09-26)

• Add a delimiter argument to tar_map() etc. for customizing separators in target names (#177, @psychelzh).
• Add "raw" hook functions (#185, @multimeric).
• Add tar_assign() (#186, https://github.com/ropensci/targets/issues/1309, @hadley).
• Merge help files of "_raw" functions (#191, @hadley).
• Supersede tar_format_feather() in favor of tar_arrow_feather() (#190).
• Supersede the tar_aws_*() target factories. They are obsolete because of the repository argument in tar_target().

tarchetypes 0.9.0 (2024-04-17)

Invalidating changes

• To align with https://github.com/ropensci/targets/issues/1244 and https://github.com/ropensci/targets/pull/1262, switch the hashing functions from digest::digest() to secretbase::siphash13().

tarchetypes 0.8.0 (2024-03-18)

• Expose the new description argument of tar_target() in targets 1.5.1.9001.
• tar_map() and other static branching target factories now append values to the target descriptions. Use the descriptions argument of those functions to customize.
• Ensure consistent repository settings in tar_change() and tar_map_rep().
• tar_knit(), tar_render(), tar_quarto(), and their "rep" and "raw" versions all gain a working_directory argument to change the working directory the report knits from. Users who set working_directory need to supply the store argument of tar_load() and tar_read() relative to the working directory so the report knows where to find the data (#169).
• tar_knit(), tar_render(), tar_quarto(), and their "raw" versions all gain an output_file argument to more conveniently set the file path to the rendered output file.
• tar_quarto() and its "rep" and "raw" versions all gain a new quarto_args argument for advanced Quarto arguments (#166, @petrbouchal).

tarchetypes 0.7.12 (2024-02-06)

• Adjust tests because group iteration is now explicitly prohibited for dynamic targets.

tarchetypes 0.7.11 (2024-01-09)

• Use tar_seed_create() and tar_seed_set() from targets.
• Document limitations of literate programming target factories like tar_render() (#158).
• Make tar_rep2() compatible with tar_map() (#165).

tarchetypes 0.7.10 (2023-12-04)

• Prepare to use tar_seed_create() and tar_seed_set() (https://github.com/ropensci/targets/issues/1139). Future versions of tarchetypes should use these package functions, but this version cannot because of the compatibility constraints of the release cycle.
• Migrate tests to targets >= 1.3.2.9004 progress statuses ("completed" instead of "built", "dispatched" instead of "started").

tarchetypes 0.7.9 (2023-10-04)

• Deprecate the packages and library arguments of tar_quarto() and tar_quarto_raw() (#155, @svraka).
• Switch to from furrr to parallel for rep_workers in tar_rep() etc. (#251, @solmos).

tarchetypes 0.7.8 (2023-09-01)

• Relax overly strict assertion on R Markdown / Quarto parameter lists (@rmgpanw, #152).
• Adjust a test to comply with upcoming targets 1.3.0.

tarchetypes 0.7.7 (2023-06-15)

• Allow format = "file_fast" in target factories.

tarchetypes 0.7.6 (2023-05-02)

• Support Quarto profiles through the QUARTO_PROFILE environment variable (#139, @andrewheiss).
• Take the basename of the source file for #129 so the output files land correctly when the source file is in a subdirectory (#129, targets issue 1047, @joelnitta).
• Use targets::tar_runtime_object()$store instead of targets::tar_runtime_object()$get_store() to ensure forward compatibility with targets.
• Use interactive test for tar_download() to avoid unpredictable network issues outside our control.

tarchetypes 0.7.5 (2023-03-07)

• Implement a new set_deps argument in the hook functions to force modified targets to keep the dependencies they had before applying the hook (#131, @edalfon).
• Forward all settings to tar_copy_target() (#131, @edalfon).
• Initialize the directory of output files in tar_quarto_rep() and tar_render_rep() (#129, @benzipperer).
• Work around https://github.com/quarto-dev/quarto-cli/pull/2456 by writing temporary local files in tar_quarto_rep() (#129, @benzipperer).

tarchetypes 0.7.4 (2023-01-06)

• Implement rep_workers to control inner parallelism in batched replication functions (#117).
• Ensure the function passed to furrr functions has environment tar_option_get("envir").
• Allow subdirectories of rendered reports with tar_quarto_rep() (#129, @mglev1n).

tarchetypes 0.7.3 (2022-11-29)

• Support nested futures for parallelism among reps within batches (#117, @kkmann).
• Add Quarto troubleshooting section to help files.

tarchetypes 0.7.2 (2022-10-31)

• Migrate away from deprecated targets::tar_path().
• Implement and return resilient seeds in batched replication (#111, #113).

tarchetypes 0.7.1 (2022-09-07)

• Document https://github.com/ropensci/tarchetypes/discussions/105 (@MarekGierlinski).
• Adapt tests to changes in tar_manfiest() default output.

tarchetypes 0.7.0 (2022-08-05)

• Add new functions tar_quarto() and tar_quarto_rep() (and "raw" versions) for Quarto documents and projects in pipelines (#89).
• Add new function tar_quarto_files() to inspect Quarto projects and documents for important files: source files to inspect for target dependencies, output documents, and Quarto-specific inputs like _quarto.yml. Uses quarto::quarto_inspect() and powers the automatic file detection in tar_quarto() etc. (#89).
• Add runtime guardrails to the params argument of tar_render_rep() (must be a data frame with unique rows (or unique elements of output_file)).
• Temporarily change root.dir when scanning for dependencies so knitr child documents work (#93, @mutlusun).
• Use format = "rds" for target_batch in tar_map_rep_raw() so the global format option does not mess up the pipeline.
• Handle non-atomic length-one list columns in tar_append_static_values().
• Allow tar_render() to work with just one row of parameters (#96, #97, @ugoebel73).
• Remove dependencies and collect garbage before running reports.
• Make sure all the target factories have memory and garbage_collection arguments.

tarchetypes 0.6.0 (2022-04-19)

• Implement tar_file_read() (#84, @petrbouchal).
• Suppress warnings for deprecated AWS formats.
• Select the correct targets in tar_select_targets() (#92, @arcruz0).
• Support the repository argument for targets >= 0.11.0.

tarchetypes 0.4.1 (2022-01-07)

• Select list elements from command1 using [[ and not [ in tar_map2() functions.

tarchetypes 0.4.0 (2021-12-10)

• Implement tar_map_rep() and tar_map_rep_raw() for dynamic batched replication within static branching for data frames (#78).
• Implement tar_map2_count(), tar_map2_count_raw(), tar_map2_size(), and tar_map2_size_raw() for batched dynamic-within-static branching for data frames (#78).
• Deprecate tar_rep_map() in favor of tar_rep2() to avoid name confusion. Likewise with tar_rep_map_raw() to tar_rep2_raw() (#78).

tarchetypes 0.3.2 (2021-10-26)

• Allow empty / NULL target list in tar_map() (@kkami1115).
• Do not claim to support "aws_file" format in tar_files() or related target factories.

tarchetypes 0.3.1 (2021-09-21)

• Relax assertion on language objects.
• Explain targets timestamps correctly in the help files of tar_age() and tar_cue_age().

tarchetypes 0.3.0 (2021-08-04)

Invalidating changes

• When names = NULL in tar_map(), use hashes instead of numeric indexes for generated target names (#67). That way, target names are no longer sensitive to the order of values, and so targets will incorrectly invalidate less often. Unfortunately, this is an invalidating change: some targets will automatically rerun after you install this version of tarchetypes. I apologize for the inconvenience this causes. However, we do need this patch in order to solve #67, and targets will incorrectly invalidate less frequently in the future.

Enhancements

• Migrate to utilities for error handling and metaprogramming exported from targets (#59).

tarchetypes 0.2.1 (2021-06-21)

Bug fixes

• Make the *_raw() target factories process command the same way whether it is an expression or ordinary language object.
• Ensure compatibility with targets 0.5.0.9000, which logs skipped targets.

New features

• Add tar_rep_map() and tar_rep_map_raw() to perform batched computation downstream of tar_rep() (#50).
• Add tar_select_names() and tar_select_targets() to make certain metaprogramming tasks easier.
• In tar_map(), attempt to convert the elements of values into lists of language objects.

tarchetypes 0.2.0 (2021-05-11)

• Allow trailing commas in tar_plan() (#40, @kendonB).
• Implement tar_age() based on tar_cue_age() (#39, @petrbouchal).
• Implement new cue factories tar_cue_age(), tar_cue_age_raw(), tar_cue_force(), and tar_cue_skip() (#39).
• Implement tar_download() (#38, @noamross, @petrbouchal)
• Set intermediate temporary directory to remove race condition in tar_render_rep() (#36, @gorgitko).
• Prefix internal condition classes with "tar_".
• Add new format helpers such as tar_aws_rds() and tar_parquet().
• Support hooks tar_hook_before(), tar_hook_inner(), and tar_hook_outer() (#44).
• Deep-copy the cue in tar_map().

tarchetypes 0.1.1 (2021-03-28)

• Unset crayon.enabled for literate programming.
• Switch meaning of %||% and %|||% to conform to historical precedent.

tarchetypes 0.1.0 (2021-02-27)

• Add new functions for easier grouping of data frames for dynamic branching: tar_group_by(), tar_group_select(), tar_group_size(), tar_group_count() (#32, @liutiming).
• In tar_render() and related functions, track the *_files/ output directory if it exists (#30).
• Implement an external walk_ast() function to make it easier for other developers to extend the static code analysis of tarchetypes (@MilesMcBain).

tarchetypes 0.0.4 (2021-02-02)

• Skip literate programming tests if pandoc is missing or has an insufficient version.
• Use explicit temp files in examples even when running inside targets::tar_dir(). (targets::tar_dir() and targets::tar_test() already run code in a temporary directory.)
• Add comments in the examples to emphasize that targets::tar_dir() runs code in a temporary directory, which means all ostensibly files created in the enclosed expression will actually be written to temporary storage and not the user's file space.

tarchetypes 0.0.2 (2021-02-01)

• Make sure every function with a help file in man/ has Rd-tags \value and \arguments.
• For every function with a help file in man/, describe the return value in the \value Rd tag. For each function that returns a target object or list of target objects, the \value tag now links to https://books.ropensci.org/targets/, the user manual where the purpose of target objects is explained, and https://books.ropensci.org/targets-design/, the design specification which documents the structure and composition of target objects.
• Ensure that examples, vignettes, and test do not write to the home file space of the user.
• Ensure that no function defined in the tarchetypes package writes by default to the home file space of the user. The paths of all output files are controlled by non-tarchetypes functions that invoke tarchetypes.

tarchetypes 0.0.1

• tar_plan() now returns a list of target objects rather than a pipeline object. Related: https://github.com/ropensci/targets/issues/253.

tarchetypes 0.0.0.9000

• First version.
• Implement tar_knitr_deps() and tar_knitr_deps_expr() to accommodate custom multi-file literate programming projects like R Markdown sites and bookdown projects (#23, @tjmahr).
