Expose an envir argument to many functions for further control over evaluation if callr_function is NULL.out.attrs when hashing groups of data frames to extend #507 to expand.grid() (#508).targets.GITHUBPAT to GITHUB_TOKEN in the tar_github_actions() YAML file (#554, @eveyp).eval chunk option in Target Markdown (#552, @fkohrt).time column for all builder targets, regardless of storage format._targets.yaml to parallel workers.exclude argument to tar_watch() and tar_watch_server() (#458, @gorkang)..gitignore file to ignore everything in _targets/meta/ except .gitignore and _targets/meta/meta.knitr engines for pipeline construction and prototyping from within literate programming documents (#469, @cderv, @nviets, @emilyriederer, @ijlyttle, @GShotwell, @gadenbuie, @tomsing1). Huge thanks to @cderv on this one for answering my deluge of questions, helping me figure out what was and was not possible in knitr, and ultimately circling me back to a successful approach.use_targets(), which writes the Target Markdown template to the project root (#469).tar_unscript() to clean up scripts written by Target Markdown.tar_make() and tar_manifest().pattern = slice() or pattern = sample() are invalid.tar_target_raw(), assert that commands have length 1 when converted to expressions.tar_cue() (@maelle).dplyr groups and "grouped_df" class in tar_group() (tarchetypes discussion #53, @kendonB).tar_read() and tar_read_raw()._targets.yaml). Fixes CRAN check errors from version 0.4.1.roxygen2 docstrings from shiny.Suggests: packages.targets.yaml in the callr process.file.rename() errors when migrating staged temporary files (#410).assert_df() from store_assert_format() instead of store_cast_object(). And now those last two functions are not called at all if the target throws an error.tar_poll() at the same time as the pipeline (#393).tar_renv() to _targets_packages.R (#397).outdated = FALSE in tar_visnetwork().tar_timestamp() and tar_timestamp_raw() to get the last modified timestamp of a target's data (#378).tar_progress_summary() to compactly summarize all pipeline progress (#380).characters argument of tar_traceback() to cap the traceback line lengths (#383).tar_watch() (#382).tar_poll() to repeatedly poll runtime progress in the R console (#381). tar_poll() is a lightweight alternative to tar_watch().tar_envvar() function to list values of special environment variables supported in targets. The help file explains each environment variable in detail._targets.yaml (#297). New functions tar_config_get() and tar_config_set() interact with the _targets.yaml file. Currently only supports the store field to set the data store path to something other than _targets/.deployment = "main" (#398, #399, #404, @pat-s).tar_traceback() (#383).tar_watch(), use shinybusy instead of shinycssloaders and keep current output on display while new output is rendering (#386, @rcorty).AWS_DEFAULT_REGION environment variable (check_region = TRUE; #400, @tomsing1).tar_meta(), return POSIXct times in the time zone of the calling system (#131).qs::qread() now that qs 0.24.1 requires stringfish >= 1.5.0 (#147, @glep).pattern = slice(...) can take multiple indexes (#406, #419, @djbirke, @alexgphayes)queue$enqueue() is now queue$prepend() and always appends to the front of the queue (#371).devtools::load_all() or similar is detected inside _targets.R (#374).feather and parquet tests on CRAN.backoff option in tar_option_set() to set the maximum upper bound (seconds) for the polling interval (#333).tar_github_actions() function to write a GitHub Actions workflow file for continuous deployment of data analysis pipelines (#339, @jaredlander).TAR_MAKE_REPORTER environment variable to globally set the reporter of the tar_make*() functions (#345, @alexpghayes).tar_make_clustermq() and tar_make_future() (#333).tar_make_future(), try to submit a target every time a worker is polled.tar_make_future(), poll workers in order of target priority.targets internal objects out of the environment in order to avoid accidental massive data transfers to workers.rlang::check_installed() inside assert_package() (#331, @malcolmbarrett).tar_destroy(destroy = "process").tar_watch(), increase default seconds to 15 (previously 5).tar_watch(), debounce instead of throttle inputs.tar_watch(), add an action button to refresh the outputs.tar_make(). Will help compute a cache key on GitHub Actions and similar services.tar_deduplicate() due to the item above.tar_target_raw(), tar_meta(), and tar_seed() (#357, @alexpghayes).%||% and %|||% to conform to historical precedent.reporter = "silent" (#364, @matthiasgomolka).envir element.tar_load(), subset metadata to avoid accidental attempts to load global objects in tidyselect calls.vctrs::vec_c() (#320, @joelnitta).names argument to tar_objects() and tar_workspaces() with tidyselect functionality.targets version) in _targets/meta/process and write new functions tar_process() and tar_pid() to retrieve the data (#291, #292).targets_only argument to tar_meta().tar_helper() and tar_helper_raw() to write general-purpose R scripts, using tidy evaluation for as a template mechanism (#290, #291, #292, #306).tar_exist_meta(), tar_exist_objects(), tar_exist_progress(), tar_exist_progress(), tar_exist_script() (#310).supervise argument to tar_watch().complete_only argument to tar_meta() to optionally return only complete rows (no NA values).callr errors and refer users to the debugging chapter of the manual.crayon if an only if the calling process is interactive (#302, @ginolhac). Can still be disabled with options(crayon.enabled = FALSE) in _targets.R.format = "url" when the HTTP response status code is not 200 (#303, @petrbouchal).extras packages to tar_renv() (to support tar_watch()).tar_watch() if _targets.R does not exist.names argument of tar_load() (#314, @jameelalsalam).nobody in custom curl handles (#315, @riazarbi).targets is somehow actively monitoring each job, e.g. through a connection or heartbeat (#318).errormode = "warn" in getVDigest() for files to work around https://github.com/eddelbuettel/digest/issues/49 for network drives on Windows. targets already runs those file checks anyway. (#316, @boshek).targets tried to load from.tar_test() now skips all tests on Solaris in order to fix the problems shown on the CRAN check page.allow and exclude to work on imports in tar_visnetwork() and tar_glimpse().visNetwork legends on right to avoid crowding the graph.force() on subpipeline objects to eliminate high-memory promises in target objects. Allows targets to be deployed to workers much faster when retreival is "main" (#279).tar_watch() app to tabulate progress on dynamic branches (#273, @mattwarkentin).type, parent, and branches in progress data for tar_watch() (#273, @mattwarkentin).fields argument in tar_progress() and default to "progress" for back compatibility (#273, @mattwarkentin).tar_progress_branches() function to tabulate branch progress (#273, @mattwarkentin).tar_watch() to toggle automatic refreshing and force a refresh..Random.seed by default in tar_visnetwork().tar_watch() app.clustermq tests on Solaris.if(FALSE) blocks from help files to fix "unexecutable code" warnings (tar_glimpse(), tar_visnetwork(), and tar_watch()).tar_edit(), tar_watch_ui(), and tar_watch_server()).tar_workspace().)CITATION._targets.R (#253).tar_pipeline() and tar_bind() because of the above (#253).visNetwork stabilization (#264, @mattwarkentin).visNetwork font size.error is "continue" (#267, @liutiming).tar_bind() (#245, @yonicd).igraph topological sort.workspaces argument to tar_option_set() to specify which targets will save their workspace files during tar_make() (#214).error = "save" to error = "workspace" to so it is clearer that saving workspaces no longer duplicates data (#214).what to destroy in tar_destroy().tar_undebug() because is redundant with tar_destroy(destroy = "workspaces").head(), tail(), and sample() to provide functionality equivalent to drake's max_expand (#56).tar_pattern() function to emulate dynamic branching outside a pipeline.level_separation argument to tar_visnetwork() and tar_glimpse() to control the aspect ratio (#226).imports argument to tar_option_set() (#239).outdated is FALSE in tar_visnetwork().tar_visnetwork() to try to account for color blindness.tar_manifest().tar_renv() now invokes _targets.R through a background process just like tar_outdated() etc. so it can account for more hidden packages (#224, @mattwarkentin).deployment equal to "main" for all targets in tar_make(). This ensures tar_make() does not waste time waiting for nonexistent files to ship over a nonexistent network file system (NFS). tar_make_clustermq() or tar_make_future() could use NFS, so they still leave deployment alone.size field to the metadata to allow targets to make better judgments about when to rehash files (#180). We now compare hashes to check file size differences instead of doing messy floating point comparisons with ad hoc tolerances. It breaks back compatibility with old projects, but the error message is informative, and this is all still before the first official release.storage, retrieval, and deployment settings (#183, @mattwarkentin).garbage_collection to a target-level setting, i.e. argument to tar_target() and tar_option_set() (#194). Previously was an argument to the tar_make*() functions.tar_name() and tar_path() to run outside the pipeline with debugging-friendly default return values.storage is "remote" (#182, @mattwarkentin).target$subpipeline rather than target$cache to make that happen (#209, @mattwarkentin).tar_bind() to combine pipeline objects.tar_seed() to get the random number generator seed of the target currently running.future::plan()s through the resources argument of tar_target() (#198, @mattwarkentin).library() instead of require() in command_load_packages().targets$cache$targets$envir to improve convenience in interactive debugging (ls() just works now.) This is reasonably safe now that the cache is populated at the last minute and cleared as soon as possible (#209, #210).
