This uses knitr::knit()
with custom options set for the Carpentries
template. It runs in a separate process to avoid issues with user-specific
options bleeding in.
Usage
build_episode_md(
path,
hash = NULL,
outdir = path_built(path),
workdir = path_built(path),
workenv = globalenv(),
profile = "lesson-requirements",
quiet = FALSE,
error = TRUE
)
Arguments
- path
path to the RMarkdown file
- hash
hash to prepend to the output. This parameter is deprecated and is effectively useless.
- outdir
the directory to write to
- workdir
the directory where the episode should be rendered
- workenv
an environment to use for evaluation. Defaults to the global environment, which evaluates to the environment from
callr::r()
.- quiet
if
TRUE
, output is suppressed, default isFALSE
to show{knitr}
output.- error
if
TRUE
(default) errors do not make an invalid build. This can be set to false to cause the build to fail if an error occurs. This is generally controlled via thefail_on_error
config option.
Examples
if (.Platform$OS.type == "windows") {
options("sandpaper.use_renv" = FALSE)
}
if (!interactive() && getOption("sandpaper.use_renv")) {
old <- renv::config$cache.symlinks()
options(renv.config.cache.symlinks = FALSE)
on.exit(options(renv.config.cache.symlinks = old), add = TRUE)
}
