\arguments{
\item{endpoint}{GitHub API endpoint. Must be one of the following forms:
\itemize{
\item \verb{METHOD path}, e.g. \code{GET /rate_limit},
\item \code{path}, e.g. \verb{/rate_limit},
\item \verb{METHOD url}, e.g. \verb{GET https://api.github.com/rate_limit},
\item \code{url}, e.g. \verb{https://api.github.com/rate_limit}.
}

If the method is not supplied, will use \code{.method}, which defaults
to \code{"GET"}.}

\item{...}{Name-value pairs giving API parameters. Will be matched into
\code{endpoint} placeholders, sent as query parameters in GET requests, and as a
JSON body of POST requests. If there is only one unnamed parameter, and it
is a raw vector, then it will not be JSON encoded, but sent as raw data, as
is. This can be used for example to add assets to releases. Named \code{NULL}
values are silently dropped. For GET requests, named \code{NA} values trigger an
error. For other methods, named \code{NA} values are included in the body of the
request, as JSON \code{null}.}

\item{per_page}{Number of items to return per page. If omitted,
will be substituted by \code{max(.limit, 100)} if \code{.limit} is set,
otherwise determined by the API (never greater than 100).}

\item{.token}{Authentication token. Defaults to \code{GITHUB_PAT} or
\code{GITHUB_TOKEN} environment variables, in this order if any is set.
See \code{\link[=gh_token]{gh_token()}} if you need more flexibility, e.g. different tokens
for different GitHub Enterprise deployments.}

\item{.destfile}{Path to write response to disk. If \code{NULL} (default),
response will be processed and returned as an object. If path is given,
response will be written to disk in the form sent.}

\item{.overwrite}{If \code{.destfile} is provided, whether to overwrite an
existing file.  Defaults to \code{FALSE}.}

\item{.api_url}{Github API url (default: \url{https://api.github.com}). Used
if \code{endpoint} just contains a path. Defaults to \code{GITHUB_API_URL}
environment variable if set.}

\item{.method}{HTTP method to use if not explicitly supplied in the
\code{endpoint}.}

\item{.limit}{Number of records to return. This can be used
instead of manual pagination. By default it is \code{NULL},
which means that the defaults of the GitHub API are used.
You can set it to a number to request more (or less)
records, and also to \code{Inf} to request all records.
Note, that if you request many records, then multiple GitHub
API calls are used to get them, and this can take a potentially
long time.}

\item{.accept}{The value of the \code{Accept} HTTP header. Defaults to
\code{"application/vnd.github.v3+json"} . If \code{Accept} is given in
\code{.send_headers}, then that will be used. This parameter can be used to
provide a custom media type, in order to access a preview feature of
the API.}

\item{.send_headers}{Named character vector of header field values
(except \code{Authorization}, which is handled via \code{.token}). This can be
used to override or augment the default \code{User-Agent} header:
\code{"https://github.com/r-lib/gh"}.}

\item{.progress}{Whether to show a progress indicator for calls that
need more than one HTTP request.}
}
\value{
Answer from the API as a \code{gh_response} object, which is also a
\code{list}. Failed requests will generate an R error. Requests that
generate a raw response will return a raw vector.
}
\description{
This is an extremely minimal client. You need to know the API
to be able to use this client. All this function does is:
\itemize{
\item Try to substitute each listed parameter into \code{endpoint}, using the
\code{{parameter}} notation.
\item If a GET request (the default), then add all other listed parameters
as query parameters.
\item If not a GET request, then send the other parameters in the request
body, as JSON.
\item Convert the response to an R list using \code{\link[jsonlite:fromJSON]{jsonlite::fromJSON()}}.

## There are two ways to send JSON data. One is that you supply one or
## more objects that will be converted to JSON automatically via
## jsonlite::toJSON(). In this case sometimes you need to use
## jsonlite::unbox() because fromJSON() creates lists from scalar vectors
## by default. The Content-Type header is automatically added in this
## case. For example this request turns on GitHub Pages, using this
## API: https://docs.github.com/v3/repos/pages/#enable-a-pages-site

gh::gh(
  "POST /repos/{owner}/{repo}/pages",
  owner = "gaborcsardi",
  repo = "playground",
  source = list(
    branch = jsonlite::unbox("master"),
    path = jsonlite::unbox("/docs")
  ),
  .send_headers = c(Accept = "application/vnd.github.switcheroo-preview+json")
)

## The second way is to handle the JSON encoding manually, and supply it
## as a raw vector in an unnamed argument, and also a Content-Type header:

body <- '{ "source": { "branch": "master", "path": "/docs" } }'
gh::gh(
  "POST /repos/{owner}/{repo}/pages",
  owner = "gaborcsardi",
  repo = "playground",
  charToRaw(body),
  .send_headers = c(
    Accept = "application/vnd.github.switcheroo-preview+json",
    "Content-Type" = "application/json"
  )
)
\dontshow{\}) # examplesIf}
