screen.rdesk_storage() key-value managers (app$prefs,
app$recent, app$shared) automatically mapping
settings to %APPDATA%, %LOCALAPPDATA%, and
%PROGRAMDATA% with permissions checks and temp
fallbacks.build_app() now strips development artifacts from the
bundled app/ directory before packaging. Previously, if the
developer’s workspace contained an renv setup, the bundled
.Rprofile would source renv/activate.R on
startup, hijacking .libPaths() away from the bundle’s
packages/library/ and causing an immediate Error
Code 1 crash. The following paths are now permanently excluded
from the bundle: .Rprofile, .Renviron,
renv/, renv.lock, .git/,
.gitignore, .gitattributes,
.Rproj.user/, .Rhistory, .RData,
tests/, .DS_Store. A message is printed during
build listing what was excluded. Apps built without these artifacts are
unaffected.build_app() now copies the developer’s currently
running R installation as the app runtime by default
(runtime_dir = NULL). Previously it downloaded a fixed R
4.4.2 portable build which caused crashes in distributed apps when
packages had been compiled for a newer R version (e.g. 4.5.x via
renv). The version mismatch between the downloaded runtime
and the bundled packages produced a cryptic shared-library ABI error on
launch.
Added rdesk_detect_r_home() (internal) which
resolves the developer’s R installation path via R.home()
with a clear error if it is not found.
Added rdesk_copy_r_runtime() (internal) which
selectively copies bin/, library/,
etc/, modules/, and include/ from
the source R installation into the bundle staging directory.
The legacy download behaviour is preserved for CI environments or
air-gapped scenarios via runtime_dir = "download". A
warning is printed advising users to prefer the default to avoid version
mismatch.
