R: List available options.

httr_options {httr} | R Documentation

## List available options.

### Description

This function lists all available options for `config()`. It provides both the short R name which you use with httr, and the longer Curl name, which is useful when searching the documentation. `curl_doc` opens a link to the libcurl documentation for an option in your browser.

### Usage

    httr_options(matches)

    curl_docs(x)

### Arguments

`matches` | If not missing, this restricts the output so that either the httr or curl option matches this regular expression.
`x` | An option name (either short or full).

### Details

RCurl and httr use slightly different names to libcurl: the initial `CURLOPT_` is removed, all underscores are converted to periods and the option is given in lower case. Thus "CURLOPT_SSLENGINE_DEFAULT" becomes "sslengine.default".

### Value

A data frame with three columns:

`httr` | The short name used in httr
`libcurl` | The full name used by libcurl
`type` | The type of R object that the option accepts

### Examples

    httr_options()
    httr_options("post")

    # Use curl_docs to read the curl documentation for each option.
    # You can use either the httr or curl option name.
    curl_docs("userpwd")
    curl_docs("CURLOPT_USERPWD")
