#' Deploy an Application
#'
#' Deploy a [shiny][shiny::shiny-package] application, an
#' [RMarkdown][rmarkdown::rmarkdown-package] document, a plumber API, or HTML
#' content to a server.
#'
#' ## Deployment records
#'
#' When deploying an app, `deployApp()` will save a deployment record that
#' makes it easy to update the app on server from your local source code. This
#' generally means that you need to only need to supply important arguments
#' (e.g. `appName`, `appTitle`, `server`/`account`) on the first deploy, and
#' rsconnect will reuse the same settings on subsequent deploys.
#'
#' The metadata needs to make this work is stored in `{appDir}/rsconnect/`.
#' You should generally check these files into version control to ensure that
#' future you and other collaborators will publish to the same location.
#'
#' If you have lost this directory, all is not lost, as `deployApp()` will
#' attempt to rediscover existing deployments. This is easiest if you are
#' updating an app that you created, as you can just supply the `appName`
#' (and `server`/`account` if you have multiple accounts) and `deployApp()`
#' will find the existing application account. If you need to update an app
#' that was created by someone else (that you have write permission) for, you'll
#' instead need to supply the `appId`.
#'
#' @param appDir A directory containing an application (e.g. a Shiny app
#'   or plumber API). Defaults to the current directory.
#' @param appFiles,appFileManifest Use `appFiles` to specify a
#'   character vector of files to bundle in the app or `appFileManifest`
#'   to provide a path to a file containing a list of such files. If neither
#'   are supplied, will bundle all files in `appDir`, apart from standard
#'   exclusions and files listed in a `.rscignore` file. See
#'   [listDeploymentFiles()] for more details.
#' @param appPrimaryDoc If the application contains more than one document, this
#'   parameter indicates the primary one, as a path relative to `appDir`. Can be
#'   `NULL`, in which case the primary document is inferred from the contents
#'   being deployed.
#' @param appSourceDoc `r lifecycle::badge("deprecated")` Please use
#'   `recordDir` instead.
#' @param appName Application name, a string consisting of letters, numbers,
#'   `_` and `-`. The application name is used to identify applications on a
#'   server, so must be unique.
#'
#'   If not specified, the first deployment will be automatically it from the
#'   `appDir` for directory and website, and from the `appPrimaryDoc` for
#'   document. On subsequent deploys, it will use the previously stored value.
#' @param appTitle Free-form descriptive title of application. Optional; if
#'   supplied, will often be displayed in favor of the name. If ommitted,
#'   on second and subsequent deploys, the title will be unchanged.
#' @param envVars A character vector giving the names of environment variables
#'   whose values should be synchronised with the server (currently supported by
#'   Connect only). The values of the environment variables are sent over an
#'   encrypted connection and are not stored in the bundle, making this a safe
#'   way to send private data to Connect.
#'
#'   The names (not values) are stored in the deployment record so that future
#'   deployments will automatically update their values. Other environment
#'   variables on the server will not be affected. This means that removing an
#'   environment variable from `envVars` will leave it unchanged on the server.
#'   To remove it, either delete it using the Connect UI, or temporarily unset
#'   it (with `Sys.unsetenv()` or similar) then re-deploy.
#'
#'   Environment variables are set prior to deployment so that your code
#'   can use them and the first deployment can still succeed. Note that means
#'   that if the deployment fails, the values will still be updated.
#' @param appId Use this to deploy to an exact known application, ignoring all
#'   existing deployment records and `appName`.
#'
#'   You can use this to update an existing application that is missing a
#'   deployment record. If you're re-deploying an application that you
#'   created it's generally easier to use `appName`; `appId` is best reserved
#'   for re-deploying apps created by someone else.
#'
#'   You can find the `appId` in the following places:
#'   * On shinyapps.io, it's the `id` listed on the applications page.
#'   * For Posit Connect, it's `guid` from the info tab on the content page.
#' @param appMode Optional; the type of content being deployed.
#'   Provide this option when the inferred type of content is incorrect. This
#'   can happen, for example, when static HTML content includes a downloadable
#'   Shiny application `app.R`. Accepted values include `"shiny"`, `"api"`,
#'   `"rmd-static"`, `"rmd-shiny"`, `"quarto-static"`, `"quarto-shiny"`, and
#'   `"static"`. The Posit Connect API Reference contains a full set of
#'   available values. Not all servers support all types of content.
#' @param contentCategory Optional; classifies the kind of content being
#'   deployed (e.g. `"plot"` or `"site"`).
#' @param account,server Uniquely identify a remote server with either your
#'   user `account`, the `server` name, or both. If neither are supplied, and
#'   there are multiple options, you'll be prompted to pick one.
#'
#'   Use [accounts()] to see the full list of available options.
#' @param upload If `TRUE` (the default) then the application is uploaded from
#'   the local system prior to deployment. If `FALSE` then it is re-deployed
#'   using the last version that was uploaded. `FALSE` is only supported on
#'   shinyapps.io; `TRUE` is required on Posit Connect.
#' @param recordDir Directory where deployment record is written. The default,
#'   `NULL`, uses `appDir`, since this is usually where you want the deployment
#'   data to be stored. This argument is typically only needed when deploying
#'   a directory of static files since you want to store the record with the
#'   code that generated those files, not the files themselves.
#' @param launch.browser If true, the system's default web browser will be
#'   launched automatically after the app is started. Defaults to `TRUE` in
#'   interactive sessions only. If a function is passed, it will be called
#'   after the app is started, with the app URL as a paramter.
#' @param on.failure Function to be called if the deployment fails. If a
#'   deployment log URL is available, it's passed as a parameter.
#' @param logLevel One of `"quiet"`, `"normal"` or `"verbose"`; indicates how
#'   much logging to the console is to be performed. At `"quiet"` reports no
#'   information; at `"verbose"`, a full diagnostic log is captured.
#' @param lint Lint the project before initiating deployment, to identify
#'   potentially problematic code?
#' @param metadata Additional metadata fields to save with the deployment
#'   record. These fields will be returned on subsequent calls to
#'   [deployments()].
#'
#'   Multi-value fields are recorded as comma-separated values and returned in
#'   that form. Custom value serialization is the responsibility of the caller.
#' @param forceUpdate What should happen if there's no deployment record for
#'   the app, but there's an app with the same name on the server? If `TRUE`,
#'   will always update the previously-deployed app. If `FALSE`, will ask
#'   the user what to do, or fail if not in an interactive context.
#'
#'   Defaults to `TRUE` when called automatically by the IDE, and `FALSE`
#'   otherwise. You can override the default by setting option
#'   `rsconnect.force.update.apps`.
#' @param python Full path to a python binary for use by `reticulate`.
#'   Required if `reticulate` is a dependency of the app being deployed.
#'   If python = NULL, and RETICULATE_PYTHON or RETICULATE_PYTHON_FALLBACK is
#'   set in the environment, its value will be used. The specified python binary
#'   will be invoked to determine its version and to list the python packages
#'   installed in the environment.
#' @param forceGeneratePythonEnvironment Optional. If an existing
#'   `requirements.txt` file is found, it will be overwritten when this argument
#'   is `TRUE`.
#' @param quarto Should the deployed content be built by quarto?
#'   (`TRUE`, `FALSE`, or `NA`). The default, `NA`, will use quarto if
#'   there are `.qmd` files in the bundle, or if there is a
#'   `_quarto.yml` and `.Rmd` files.
#'
#'   (This option is ignored and quarto will always be used if the
#'   `metadata` contains `quarto_version` and `quarto_engines` fields.)
#' @param appVisibility One of `NULL`, `"private"`, or `"public"`; the
#'   visibility of the deployment. When `NULL`, no change to visibility is
#'   made. Currently has an effect only on deployments to shinyapps.io.
#' @param image Optional. The name of the image to use when building and
#'   executing this content. If none is provided, Posit Connect will
#'   attempt to choose an image based on the content requirements. You can
#'   override the default by setting the environment variable `RSCONNECT_IMAGE`.
#' @param envManagement Optional. Should Posit Connect install R and Python
#'   packages for this content? (`TRUE`, `FALSE`, or `NULL`).
#'   The default, `NULL`, will not write any values to the bundle manifest,
#'   and Connect will fall back to the application default environment
#'   management strategy, or the server default if no application default
#'   is defined.
#'
#'   (This option is a shorthand flag which overwrites the values of both
#'   `envManagementR` and `envManagementPy`.)
#' @param envManagementR Optional. Should Posit Connect install R packages
#'   for this content? (`TRUE`, `FALSE`, or `NULL`). The default, `NULL`, will
#'   not write any values to the bundle manifest, and Connect will fall back to
#'   the application default R environment management strategy, or the server
#'   default if no application default is defined.
#'
#'   (This option is ignored when `envManagement` is non-`NULL`.)
#' @param envManagementPy Optional. Should Posit Connect install Python packages
#'   for this content? (`TRUE`, `FALSE`, or `NULL`). The default, `NULL`, will
#'   not write any values to the bundle manifest, and Connect will fall back to
#'   the application default Python environment management strategy, or the
#'   server default if no application default is defined.
#'
#'   (This option is ignored when `envManagement` is non-`NULL`.)
#' @param space Optional. For Posit Cloud, the id of the space where the content
#'   should be deployed. If none is provided, content will be deployed to the
#'   deploying user's workspace or deployed to the same space in case of
#'   redeploy.
