Down with drake_config()!

Version 7.10.0

Unavoidable but minor breaking changes

These changes invalidate some targets in some workflows, but they are necessary bug fixes.

• Remove spurious local variables detected in $<-() and @<-() (#1144).
• Avoid target names with trailing dots (#1147, @plebejer).

Bug fixes

• Handle unequal list columns in bind_plans() (#1136, @jennysjaarda).
• Handle non-vector sub-targets in dynamic branching (#1138).
• Handle calls in analyze_assign() (#1119, @jennysjaarda).
• Restore correct environment locking (#1143, @kuriwaki).
• Log "running" progress of dynamic targets.
• Log dynamic targets as failed if a sub-target fails (#1158).

New features

• Add a new "fst_tbl" format for large tibble targets (#1154, @kendonB).
• Add a new format argument to make(), an optional custom storage format for targets without an explicit target(format = ...) in the plan (#1124).
• Add a new lock_cache argument to make() to optionally suppress cache locking (#1129). (It can be annoying to interrupt make() repeatedly and unlock the cache manually every time.)
• Add new functions cancel() and cancel_if() function to cancel targets mid-build (#1131).
• Add a new subtarget_list argument to loadd() and readd() to optionally load a dynamic target as a list of sub-targets (#1139, @MilesMcBain).
• Prohibit dynamic file_out() (#1141).

Enhancements

• Check for illegal formats early on at the drake_config() level (#1156, @MilesMcBain).
• Smoothly deprecate the config argument in all user-side functions (#1118, @vkehayas). Users can now supply the plan and other make() arguments directly, without bothering with drake_config(). Now, you only need to call drake_config() in the _drake.R file for r_make() and friends. Old code with config objects should still work. Affected functions:
  • make()
  • outdated()
  • drake_build()
  • drake_debug()
  • recoverable()
  • missed()
  • deps_target()
  • deps_profile()
  • drake_graph_info()
  • vis_drake_graph()
  • sankey_drake_graph()
  • drake_graph()
  • text_drake_graph()
  • predict_runtime(). Needed to rename the targets argument to targets_predict and jobs to jobs_predict.
  • predict_workers(). Same argument name changes as predict_runtime().
• Because of #1118, the only remaining user-side purpose of drake_config() is to serve functions r_make() and friends.
• Document the limitations of grouping variables (#1128).
• Handle the @ operator. For example, in the static code analysis of x@y, do not register y as a dependency (#1130, @famuvie).
• Remove superfluous/incorrect information about imports from the output of deps_profile() (#1134, @kendonB).
• Append hashes to deps_target() output (#1134, @kendonB).
• Add S3 class and pretty print method for drake_meta_() objects objects.
• Use call stacks instead of environment inheritance to power drake_envir() and id_chr() (#1132).
• Allow drake_envir() to select the environment with imports (#882).
• Improve visualization labels for dynamic targets: clarify that the listed runtime is a total runtime over all sub-targets and list the number of sub-targets.
