- name: "activate.prompt"
  type: "logical[1]"
  default: true
  description: >
    Automatically prompt the user to activate the current project, if it does
    not appear to already be activated? This is mainly useful to help ensure
    that calls to `renv::snapshot()` and `renv::restore()` use the project
    library. See `?renv::activate` for more details.

- name: "autoloader.enabled"
  type: "logical[1]"
  default: true
  description: >
    Enable the renv auto-loader? When `FALSE`, renv will not
    automatically load a project containing an renv autoloader within
    its `.Rprofile`. In addition, renv will not write out the project
    auto-loader in calls to `renv::init()`.

- name: "auto.snapshot"
  type: "logical[1]"
  default: false
  description: >
    Automatically snapshot changes to the project library when the project
    dependencies change?

- name: "bioconductor.init"
  type: "*"
  default: ~
  description: >
    The default value to be used for the `bioconductor` parameter in calls
    to `renv::init()`. This can be used if you'd like to automatically enable
    or disable Bioconductor by default for newly-initialized `renv` projects.
    See the documentation in `?renv::init` for more details.

- name: "bitbucket.host"

  default: "api.bitbucket.org/2.0"
  description: >
    The default Bitbucket host to be used during package retrieval.

- name: "copy.method"
  type: "*"
  default: "auto"
  description: >
    The method to use when attempting to copy directories. See **Copy Methods**
    for more information.

- name: "crandb.enabled"
  type: "logical[1]"
  default: false
  description: >
    Use the [crandb](https://github.com/r-hub/crandb) service when
    looking up packages from CRAN which are not available in the configured
    repositories? When enabled, renv will query the crandb API to find the
    latest version of a package compatible with the current version of R.
    This can be useful when an older version of R is being used, and the
    latest version of a package on CRAN requires a newer version of R.
    Disabled by default.

- name: "connect.timeout"
  type: "integer[1]"
  default: 20
  description: >
    The amount of time to spend (in seconds) when attempting to download
    a file. Only applicable when the `curl` downloader is used.

- name: "connect.retry"
  type: "integer[1]"
  default: 3
  description: >
    The number of times to attempt re-downloading a file, when transient
    download errors occur. Only applicable when the `curl` downloader is used.

- name: "cache.enabled"
  type: "logical[1]"
  default: true
  description: >
    Enable the global renv package cache? When active, renv will install
    packages into a global cache, and link or copy packages from the cache
    into your \R library as appropriate. This can greatly save on disk space
    and install time when \R packages are shared across multiple projects in
    the same environment.

- name: "cache.symlinks"
  type: "logical[1]"
  code: >
    .Platform$OS.type == "unix"
  description: >
    Symlink packages from the global renv package cache into your project
    library? When `TRUE`, renv will use symlinks (or, on Windows, junction
    points) to reference packages installed in the cache. Set this to `FALSE`
    if you'd prefer to copy packages from the cache into your project library.
    Enabled by default, except on Windows where this feature is only enabled
    if the project library and global package cache are on the same volume.

- name: "dependency.errors"
  type: "character[1]"
  default: "reported"
  description: >
    Many renv APIs require the enumeration of your project's \R package
    dependencies. This option controls how errors that occur during this enumeration
    are handled. By default, errors are reported but are non-fatal. Set this to `"fatal"`
    to force errors to be fatal, and `"ignored"` to ignore errors altogether. See
    [`dependencies()`] for more details.

- name: "dependencies.limit"
  type: "integer[1]"
  default: 1000
  description: >
    By default, renv reports if it discovers more than this many files when
    looking for dependencies, as that may indicate you are running
    `dependencies()` in the wrong place. Set to `Inf` to disable this warning.

- name: "exported.functions"
  type: "character[*]"
  default: "*"
  description: >
    When `library(renv)` is called, should its exports be placed on the search
    path? Set this to `FALSE` to avoid issues that can arise with, for example,
    `renv::load()` masking `base::load()`. In general, we recommend referencing
    renv functions from its namespace explicitly; e.g. prefer
    `renv::snapshot()` over `snapshot()`.

    By default, all exported renv functions are attached and placed on the
    search path, for backwards compatibility with existing scripts using renv.


- name: "external.libraries"
  type: "character[*]"
  default: ~
  description: >
    A character vector of external libraries, to be used in tandem with
    your projects. Be careful when using external libraries: it's possible that things
    can break within a project if the version(s) of packages used in your project
    library happen to be incompatible with packages in your external libraries; for
    example, if your project required `xyz 1.0` but `xyz 1.1` was present and loaded
    from an external library. Can also be an \R function that provides the paths to
    external libraries. Library paths will be expanded via [`.expand_R_libs_env_var()`]
    as necessary.

- name: "filebacked.cache"
  type: "logical[1]"
  default: true
  description: >
    Enable the renv file-backed cache? When enabled, renv will cache the
    contents of files that are read (e.g. DESCRIPTION files) in memory, thereby
    avoiding re-reading the file contents from the filesystem if the file has
    not changed. renv uses the file `mtime` to determine if the file has
    changed; consider disabling this if `mtime` is unreliable on your system.

- name: "github.host"
  type: "character[1]"
  default: "api.github.com"
  description: >
    The default GitHub host to be used during package retrieval.

- name: "hydrate.libpaths"
  type: "character[*]"
  default: ~
  description: >
    A character vector of library paths, to be used by [hydrate()]
    when attempting to hydrate projects. When empty, the default set of library paths
    (as documented in `?renv::hydrate`) are used instead. See [`hydrate()`] for more details.

- name: "install.build"
  type: "logical[1]"
  default: false
  description: >
    Should downloaded package archives be built (via `R CMD build`) before installation?
    When TRUE, package vignettes will also be built as part of package installation.
    Because building packages before installation may require packages within 'Suggests'
    to be available, this option is not enabled by default.

- name: "install.remotes"
  type: "logical[1]"
  default: true
  description: >
    Should renv read a package's `Remotes:` field when determining how
    package dependencies should be installed?

- name: "install.shortcuts"
  type: "logical[1]"
  default: true
  description: >
    Allow for a set of 'shortcuts' when installing packages with renv? When
    enabled, if renv discovers that a package to be installed is already
    available within the user or site libraries, then it will install a
    local copy of that package.

- name: "install.staged"
  type: "logical[1]"
  default: true
  description: >
    DEPRECATED: Please use `renv.config.install.transactional` instead.

- name: "install.transactional"
  type: "logical[1]"
  default: true
  description: >
    Perform a transactional install of packages during install and restore? When
    enabled, renv will first install packages into a temporary library, and later
    copy or move those packages back into the project library only if all packages
    were successfully downloaded and installed. This can be useful if you'd like to
    avoid mutating your project library if installation of one or more packages fails.

- name: "install.jobs"
  type: "integer[1]"
  default: 4
  description: >
    The number of packages to install concurrently during `install()` and
    `restore()`. Packages within the same dependency wave are installed in
    parallel using this many concurrent R CMD INSTALL processes. Set to `1L`
    for sequential installation.

- name: "install.verbose"
  type: "logical[1]"
  default: false
  description: >
    Be verbose when installing R packages from sources? When `TRUE`, renv will
    stream any output generated during package build + installation to the console.

- name: "locking.enabled"
  type: "logical[1]"
  default: false
  description: >
    Use interprocess locks when invoking methods which might mutate the project
    library? Enable this to allow multiple processes to use the same renv
    project, while minimizing risks relating to concurrent access to the
    project library. Disable this if you encounter locking issues. Locks are stored
    as files within the project at `renv/lock`; if you need to manually remove a
    stale lock you can do so via `unlink("renv/lock", recursive = TRUE)`.

- name: "mran.enabled"

    repository URLs used by PPM into binary URLs as appropriate for the
    current Linux platform. Set this to `FALSE` if you'd like to continue using
    source-only PPM URLs, or if you find that renv is improperly transforming
    your repository URLs. You can still set and use PPM repositories with this
    option disabled; it only controls whether renv tries to transform source
    repository URLs into binary URLs on your behalf.

- name: "ppm.default"
  type: "logical[1]"
  default: true
  description: >
    Boolean; should new projects use the
    [Posit Public Package Manager](https://packagemanager.posit.co/)
    instance by default? When `TRUE` (the default), projects initialized with
    `renv::init()` will use the P3M instance if the `repos` R option has not

- name: "repos.override"
  type: "character[*]"
  default: ~
  description: >
    Override the R package repositories used during [`restore()`]? Primarily
    useful for deployment / continuous integration, where you might want to enforce
    the usage of some set of repositories over what is defined in `renv.lock` or otherwise
    set by the R session.

    This can be specified as a single repository URL (e.g., "https://cloud.r-project.org"),
    or as multiple named repositories separated by semicolons using the format

- name: "sandbox.enabled"
  type: "logical[1]"
  default: true
  description: >
    Enable sandboxing for renv projects? When active, renv will attempt
    to sandbox the system library, preventing non-system packages installed in the
    system library from becoming available in renv projects. (That is, only packages
    with priority `"base"` or `"recommended"`, as reported by `installed.packages()`,
    are made available.)

    Sandboxing is done by linking or copying system packages into a separate
    library path, and then instructing R to use that library path as the system
    library path. In some environments, this action can take a large amount of
    time -- in such a case, you may want to disable the renv sandbox.

- name: "shims.enabled"
  type: "logical[1]"
  default: true
  description: >
    Should renv shims be installed on package load? When enabled, renv
    will install its own shims over the functions `install.packages()`, `update.packages()`
    and `remove.packages()`, delegating these functions to [`renv::install()`],
    [`renv::update()`] and [`renv::remove()`] as appropriate.

- name: "snapshot.inference"
  type: "logical[1]"
  default: true
  description: >
    For packages which were installed from local sources, should renv try to infer the
    package's remote from its DESCRIPTION file? When `TRUE`, renv will check and prompt
    you to update the package's DESCRIPTION file if the remote source can be ascertained.
    Currently, this is only implemented for packages hosted on GitHub. Note that this
    check is only performed in interactive R sessions.

- name: "snapshot.validate"
  type: "logical[1]"
  default: true
  description: >
    Validate \R package dependencies when calling snapshot? When `TRUE`,
    renv will attempt to diagnose potential issues in the project library before
    creating `renv.lock` -- for example, if a package installed in the project library
    depends on a package which is not currently installed.

- name: "startup.quiet"
  type: "logical[1]"

- name: "updates.check"
  type: "logical[1]"
  default: false
  description: >
    Check for package updates when the session is initialized? This can
    be useful if you'd like to ensure that your project lockfile remains up-to-date

- name: "updates.parallel"
  type: "*"
  default: 2
  description: >
    Check for package updates in parallel? This can be useful when a large
