Downloads the Zig release version for this platform, verifies the
archive against the size and SHA-256 that
https://ziglang.org/download/index.json publishes (pinned in rzig), and
unpacks it into dir. find_zig() and the configure scripts of
packages created with use_rzig() find compilers installed in
zig_home(), so R CMD INSTALL of such a package needs no further setup.
Usage
install_zig(
version = "0.16.0",
dir = zig_home(),
mirrors = TRUE,
quiet = FALSE
)
uninstall_zig(version = NULL, dir = zig_home())
zig_home()Value
install_zig(): the path of the zig executable, invisibly.
uninstall_zig(): the folders removed, invisibly. zig_home(): a path.
Details
The archive (about 55 MB, about 300 MB unpacked) comes from one of the
community mirrors of Zig, tried in an order that varies between sessions,
or else from ziglang.org, as the Zig Software Foundation asks of automated
downloads. A download whose size or SHA-256 differs from the pin is
deleted before anything is extracted or run. An existing installation of
the same version is reused. uninstall_zig() removes installations made by
install_zig().
zig_home() is the folder named by the environment variable
RZIG_ZIG_HOME, or zig in the user cache folder of rzig
(tools::R_user_dir()).
Examples
zig_home()
#> [1] "/home/runner/.cache/R/rzig/zig"
if (FALSE) { # \dontrun{
install_zig("0.16.0")
find_zig()
} # }
