box 1.2.1

Bug fixes

• Suppress a spurious internal warning upon reloading a module, caused by a dependent module being imported more than once (#363).

Miscellaneous

• Changed the way environments are locked, since environment unlocking is no longer allowed by the CRAN policies.

box 1.2.0

Breaking changes

• Deprecation warning: in the next major version, ‘box’ will read the environment variable R_BOX_PATH only once, at package load time. Modifying its value afterwards will have no effect, unless the package is unloaded and reloaded.
• ‘box’ no longer supports R 3.5 since the R build infrastructure (in particular ‘devtools’) no longer supports it.

Bug fixes

• Fix backports definitions so that they work in binary packages that were created using newer R versions (#347).
• Replace call to function that was added in R 4.0.0 to make package work again in R 3.6.3 (#335).

New and improved features

• Prevent accidental misuse by checking that arguments to box::file() and box::export() are unnamed (#334).
• The method argument of box::register_S3_method() is now optional (#305).

box 1.1.3

Bug fixes

• Silence warnings caused by an internal change of the R HTML help display functionality (#255, #278).
• Support loading modules inside RStudio even when ‘rstudioapi’ is not installed (#293).
• Do not crash in the presence of missing arguments in function calls inside modules (#266).
• Support trailing comma in in reexports via box::use() (#263).

New and improved features

• Add box::topenv() function, analogous to base::topenv() (#310).
• Support lazy loading data from packages (#219).
• Improve error messages for invalid box::use() declarations (#253).
• Add box::purge_cache() function to force reloading all modules (@kamilzyla, #236).

box 1.1.2

(Version update for technical reasons; no changes.)

box 1.1.1

(Version update for technical reasons; no changes.)

box 1.1.0

Breaking changes

• Modules without any @export declarations now export all visible names (= names not starting with a dot). To restore the previous behaviour of a module without exports, call box::export() inside the module.
• box::set_script_path() now returns the full path previously set, as documented, not just its parent directory’s path. Existing code that relies on this function’s previously incorrect behaviour will need to be updated.

Bug fixes

• Work around broken isRunning() function in Shiny ≥1.6.0 (#237).
• Return the full path from box::set_script_path(), as documented, not just the parent directory’s path; box::script_path() now also returns that path without requiring the user to set a new path (#239).
• Improve detection of whether code is called from inside RStudio (#225).
• Work around an R bug in path handling on non-Windows platforms when paths passed to the R binary contain spaces.
• Make HTML rendering of interactive module help work on Windows (#223).
• Prevent a segfault in R ≤ 3.6.1 caused by a missing declaration of an internal C symbol (#213).
• Allow exporting modules that were previously loaded using a different prefix (#211).
• Reload dependencies when reloading a module (#39, #165, #195).
• Don’t crash in the presence of nested, expanded functions inside modules (#203, #204).

New and improved features

• Improve error messages when calling box::unload() or box::reload() with an invalid argument (#232).
• Improve error messages when a module cannot be found or when there’s a syntactic error in a box::use() declaration.
• Support legacy modules (aka. R scripts) better by exporting all visible names (#207).
• Permit specifying exports by calling box::export() instead of via @export declarations (#227).
• Add a standard module for core R packages (#200).
• Warn when legacy functions are imported inside modules (#206).
• Support modules without exports.

box 1.0.2

New and improved features

• Make box::help() work with attached objects (#170).
• Allow trailing comma in attach specification (#191).
• Allow loading the main module of a submdule via box::use(.[...]) (#192).

box 1.0.1

Bug fixes

• [...] now correctly attaches exported names starting with a dot (#186).

New and improved features

• Allow trailing comma in box::use() declaration (#172).
• Support loading local modules when executing files opened in RStudio (#187).
• Improve error message when accessing a non-existent module export via $ (#180).
• Improve performance of accessing a module export via $ (#180).
• Add explicit support for loading local modules inside ‘testthat’ unit tests (#188).

Complete rewrite; see the migration guide for more information.
