• Fixes for CRAN checks.

CRAN release: 2022-10-28

• dev_topic_find() is now exported (#215).

• dev_help() will remind you to run pkgload::load_all() if no in-development packages are found (#221).

• Shimmed ? now works even if you’ve renamed the documentation topic (#220).

• dev_help() now works with an RStudio daily to deliver a rendered development documentation that includes working images and links (#228).

CRAN release: 2022-06-27

• load_all() now calls rlang::check_installed() to prompt whether to install missing packages.

Outdated and missing dependencies are installed using pak if installed. If not, the remotes package is used if installed. Otherwise install.packages() is used as a last resort but this method does not support Remotes fields.

• load_all() gains an attach argument set to TRUE by default (#209). If set to FALSE, load_all() creates a new namespace but doesn’t create a package environment on the search path. In this case, it is more similar to loadNamespace() than to library().

• Improved the way help pages are displayed in RStudio. This makes the behaviour within and outside RStudio consistent and fixes issues with Rd macros (#120).

• unregister() is now exported. This is a gentler version of unload() which removes the package from the search path, unregisters methods, and unregisters the namespace. However it doesn’t try to unload the namespace or its DLL so that dangling references keep working.

• User onLoad hooks are now run after exports have been populated. This allows the hook to use exported functions.

• The loaded namespace is now locked just before user onLoad hooks are run. This better reproduced the namespace sealing behaviour of regular loading.

The package environment environment is now locked as well before both the user and package onAttach hooks are run.

• Added support for loading a .so or .dll file from the inst folder via a new library.dynam() shim (@ethanplunkett, #48).

• The system.file() shim now fails if you supply a path that starts with inst to better reproduce the behaviour with installed packages (#104).

• load_all() now imports its dependencies lazily to avoid parallel installation issues (#89).

• Unknown Rd macros no longer trigger a warning when building the package topic index (#119).

• load_all(compile = TRUE) now forces a full recompilation (#93).

• The advice about running rm() to remove conflicts with objects in the global environment is now clickable in RStudio (#199).

• New is_loading() predicate to detect whether load_all() is currently running (#134).

• .dynLibs() is no longer emptied when package with no DLL is unloaded (#176).

• The ? shim no longer interprets ?"/" as a path (#198).

• rstudioapi is no longer a hard dependency of pkgload (#187).

• Errors thrown in user hooks are now demoted to a warning condition. Previously they were demoted using try(), making it harder to debug them.

• load_all() correctly re-loads modified translations, avoiding the usual gettext behaviour.

CRAN release: 2021-11-30

• Lionel Henry is now the maintainer.

• load_all() automatically registers package translations, if found.

CRAN release: 2021-10-13

• pkgload now forces all bindings on unload. This fixes errors and inconsistencies when dangling references force lazy bindings after unload or reload.

• load_all() now restores S3 methods registered by third party packages (#163).

• load_dll() will now preserve the DLL name when loading instead of always using the package name. This allows packages to include DLL’s with different names (#162, @dfalbel).

CRAN release: 2021-09-11

CRAN release: 2021-04-06

• unload() no longer unregisters methods for generics of the package being unloaded. This way dangling references to generics defined in the stale namespace still work as expected (r-lib/vctrs#1341).

• load_all() will now work for packages that have testthat tests but do not have testthat installed (#151)

• The pkgbuild dependency has been moved to Suggests, as it is only needed for packages with compiled code.

• load_all() will now work for packages that have testthat tests but do not have testthat installed (#151)

• load_all(warn_conflicts = TRUE) becomes more narrow and only warns when a function in the global environment masks a function in the package, consistent with the docs (#125, #143 @jennybc).

• load_all() no longer does a comprehensive check on the DESCRIPTION file when loading, instead just checking that it exists and starts with Package (#149, @malcolmbarrett)

• unload() no longer warns when it can’t unload a namespace.

CRAN release: 2021-02-23

• Fix test failure in R 4.1 with regards to S4 method registration

• load_all() now preserves existing namespaces in working order. In particular, it doesn’t unload the package’s shared library and keeps it loaded instead. When reloading, a copy of the SO for the new namespace is loaded from a temporary location. These temporary SOs are only unloaded on GC and deleted from their temporary location via a weak reference attached to the namespace.

This mechanism ensures that lingering references to the namespace keep working as expected. Consequently the namespace propagation routine that was added to pkgload as a workaround has been removed.

Note that .Call() invocations that pass a string symbol rather than a structured symbol may keep crashing, because R will look into the most recently loaded SO of a given name. Since symbol registration is now the norm, we don’t expect this to cause much trouble.

• load_all() no longer forces all bindings of a namespace to avoid lazy-load errors. Instead, it removes exported S3 methods from the relevant tables.

• This improves the loading behaviour with packages that define objects in their namespaces lazily (e.g. with delayedAssign()).

• This also makes load_all() more predictable after a method has been removed from the package. It is now actually removed from the generic table. It would previously linger until R was restarted.

• If load_all() attaches testthat, it automatically suppresses conflicts.

CRAN release: 2020-05-29

• dev_example() now works after removing an inconsistent call to load_all() (@riccardoporreca, #122).

• load_all() now issues a warning if exported objects conflict with objects defined in the global environment (#112)

• run_example() arguments run and test are deprecated in favor of the (hopefully) more clear run_dontrun and run_donttest (#107).

• Internal fixes for compatibility with the future 4.1.0 release.

CRAN release: 2018-10-29

• shim_question() now works for topics from the R base package that are passed with the double colon operator (e.g. base::min) (@mdequeljoe, #99).

• load_all() now allows using explicitly qualified, exported names in test helpers (@klmr, #95).

• load_all() gains a compile argument which controls more finely whether to compile the code or not. The recompile argument is now deprecated and will be removed in a future version of pkgload.

CRAN release: 2018-10-11

• unload() now only removes S4 classes which were generated in the package being unloaded (#75)

• help() will no longer error when trying to load package level help (#67).

• Trailing slashes now removed from all paths, which fixes issues on Windows (#73).

• load_dll() now fixed in R-devel (#77).

• The help shim’s now work for ::: inputs (#72).

CRAN release: 2018-07-07

• load_all() now updates imports of dependent packages when a package is reloaded (#59).

• load_all() now assigns DESCRIPTION/Depends to .Depends object of package environment. (@yiufung pkgload#61)

• load_all() now attaches testthat if the attach_testthat option is TRUE. This allows load_all() to more closely mimic the testing environment. (#56)

• check_dep_version() and check_suggested() are now exported.

• check_dep_version() now emits a warning and returns FALSE rather than aborting. (#47)

• Package imports are now exported when using load_all(). This behavior can be disabled by using load_all(export_imports = FALSE).

• The as.package() and is.package() functions have been removed.

• load_code(), load_data(), load_dll(), load_all(), parse_ns_file() all now take an explicit path rather than a path or a package object.

• imports_env(), ns_env(), pkg_env() and unload() now take a package name rather than a path or a package object.

• run_example() now works on R 3.1.

• unload() now unloads S4 classes for packages loaded with library() as well as load_all() (#46).

• load_all() gains a helpers option to specify whether or not to source testthat helpers. (@pitakakariki devtools #1202)

• load_all() now sources the testthat helpers in the namespace environment rather than the package environment (#40).

• load_all() now sets the NOT_CRAN environment variable when it sources testthat helpers. It also sets DEVTOOLS_LOAD to “true” so that you can check whether they are run during package loading.

• dev_topic_path() now only returns the last path found, fixing an error when a package has both a package function level help with the same name. (#21)

• New function is_dev_package() to determine if a given package has been loaded by pkgload::load_all() (#2).

• load_all() no longer updates the collate directive. Instead this functionality has been moved to devtools::document().

• dev_help() now optionally takes a character vector of packages to search within. This replaces find_topic().

• dev_topic_index_reset() is now exported, and allows you to reset the topic index associated with a given package.

• Added a NEWS.md file to track changes to the package.

• Initial release from code spun off from devtools
