-## HTTPie: cURL for humans
-
-[![Build Status](https://secure.travis-ci.org/jkbr/httpie.png)](http://travis-ci.org/jkbr/httpie)
-
-
-HTTPie is a CLI frontend for [python-requests](http://python-requests.org) built out of frustration. It provides an `http` command that can be used to easily issue HTTP requests. It is meant to be used by humans to interact with HTTP-based APIs and web servers. The response headers are colorized and the body is syntax-highlighted if its `Content-Type` is known to [Pygments](http://pygments.org/) (unless the output is redirected).
-
-![httpie](https://github.com/jkbr/httpie/raw/master/httpie.png)
-
-### Installation
-
-Latest stable version using [pip](http://www.pip-installer.org/en/latest/index.html):
-
-    pip install -U httpie
-    # easy_install httpie
-
-Master:
-
-    pip install -U https://github.com/jkbr/httpie/tarball/master
-
-
-### Usage
-
-    http [flags] METHOD URL [header:value | data-field-name=value]*
-
-The default request `Content-Type` is `application/json` and data fields are automatically serialized as a JSON `Object`, so this:
-
-    http PATCH api.example.com/person/1 X-API-Token:123 name=John email=john@example.org
-
-Will issue the following request:
-
-    PATCH /person/1 HTTP/1.1
-    User-Agent: HTTPie/0.1
-    X-API-Token: 123
-    Content-Type: application/json; charset=utf-8
-
-    {"name": "John", "email": "john@example.org"}
-
-You can pass other types than just strings using the `field:=value` notation. It allows you to set arbitrary JSON to the data fields:
-
-    http PUT httpie.org/pies bool:=true list:=[1,2,3] 'object:={"a": "b", "c": "d"}'
-
-Produces the following JSON request:
-
-    {"bool": true, "list": [1, 2, 3], "object": {"a": "b", "c": "d"}}
-
-You can use the `--form` flag to set `Content-Type` and serialize the data as `application/x-www-form-urlencoded`.
-
-The data to be sent can also be passed via `stdin`:
-
-    http PUT api.example.com/person/1 X-API-Token:123 < person.json
-
-Most of the flags mirror the arguments you would use with `requests.request`. See `http -h`:
-
-    usage: http [-h] [--version] [--json | --form] [--traceback]
-                [--pretty | --ugly] [--headers | --body] [--style STYLE]
-                [--auth AUTH] [--verify VERIFY] [--proxy PROXY]
-                [--allow-redirects] [--file PATH] [--timeout TIMEOUT]
-                METHOD URL [items [items ...]]
-
-    HTTPie - cURL for humans.
-
-    positional arguments:
-      METHOD                HTTP method to be used for the request (GET, POST,
-                            PUT, DELETE, PATCH, ...).
-      URL                   Protocol defaults to http:// if the URL does not
-                            include it.
-      items                 HTTP header (key:value), data field (key=value) or raw
-                            JSON field (field:=value).
-
-    optional arguments:
-      -h, --help            show this help message and exit
-      --version             show program's version number and exit
-      --json, -j            Serialize data items as a JSON object and set Content-
-                            Type to application/json, if not specified.
-      --form, -f            Serialize data items as form values and set Content-
-                            Type to application/x-www-form-urlencoded, if not
-                            specified.
-      --traceback           Print exception traceback should one occur.
-      --pretty, -p          If stdout is a terminal, the response is prettified by
-                            default (colorized and indented if it is JSON). This
-                            flag ensures prettifying even when stdout is
-                            redirected.
-      --ugly, -u            Do not prettify the response.
-      --headers, -t         Print only the response headers.
-      --body, -b            Print only the response body.
-      --style STYLE, -s STYLE

-      --verify VERIFY       Set to "yes" to check the host's SSL certificate. You
-                            can also pass the path to a CA_BUNDLE file for private
-                            certs. You can also set the REQUESTS_CA_BUNDLE
-                            environment variable.
-      --proxy PROXY         String mapping protocol to the URL of the proxy (e.g.
-                            http:foo.bar:3128).
-      --allow-redirects     Set this flag if full redirects are allowed (e.g. re-

-      --file PATH           File to multipart upload
-      --timeout TIMEOUT     Float describes the timeout of the request (Use

+=======================
+HTTPie: cURL for humans
+=======================
+
+**HTTPie is a CLI HTTP utility** built out of frustration with existing tools.
+Its goal is to make CLI interaction with HTTP-based services as
+**human-friendly** as possible. HTTPie provides an ``http`` command that allows
+for issuing **arbitrary HTTP** requests using a **simple and natural syntax**,
+and displays **colorized responses**:
+
+.. image:: https://github.com/jkbr/httpie/raw/master/httpie.png
+    :alt: HTTPie compared to cURL
+
+HTTPie supports Python 2.6+ (including Python 3.x and PyPy) and has been tested
+under Mac OS X, Linux and Windows. It also has a
+comprehensive `suite of tests`_ with `continuous integration`_.
+
+Under the hood, the excellent `Requests`_ and `Pygments`_ Python libraries
+are used.
+
+
+Installation
+============
+
+The latest **stable version** of HTTPie can always be installed or updated
+to via `pip`_ (prefered)
+or ``easy_install``::
+
+    pip install -U httpie
+    # easy_install pip
+
+Or, you can install the **development version** directly from GitHub:
+
+.. image:: https://secure.travis-ci.org/jkbr/httpie.png
+    :target: http://travis-ci.org/jkbr/httpie
+    :alt: Build Status of the master branch
+
+::
+
+    pip install -U https://github.com/jkbr/httpie/tarball/master
+
+There are also packages available for `Ubuntu`_, `Debian`_ and possibly other
+distributions as well.
+
+
+Usage
+=====
+
+Hello world::
+
+    http httpie.org
+
+Synopsis::
+
+    http [flags] [METHOD] URL [items]
+
+There are five different types of key/value pair ``items`` available:
+
++-----------------------+-----------------------------------------------------+
+| **Headers**           | Arbitrary HTTP headers. The ``:`` character is      |
+| ``Name:Value``        | used to separate a header's name from its value,    |
+|                       | e.g., ``X-API-Token:123``.                          |
++-----------------------+-----------------------------------------------------+
+| **Simple data         | Included in the request body and depending on the   |
+| fields**              | ``Content-Type`` they are automatically serialized  |
+| ``field=value``       | as a JSON ``Object`` (default) or                   |
+|                       | ``application/x-www-form-urlencoded``               |
+|                       | (``--form``/  ``-f``). Data items use ``=``         |
+|                       | as the separator, e.g., ``hello=world``.            |
++-----------------------+-----------------------------------------------------+
+| **Raw JSON fields**   | Useful when the ``Content-Type`` is JSON and one or |
+| ``field:=json``       | more fields need to be a ``Boolean``, ``Number``,   |
+|                       | nested ``Object``, or an ``Array``. It's because    |
+|                       | simple data items are always serialized as a        |
+|                       | ``String``. E.g., ``pies:=[1,2,3]``, or             |
+|                       | ``'meals:=["ham","spam"]'`` (note the quotes).      |
+|                       | It may be more convenient to pass the whole JSON    |
+|                       | body via ``stdin`` when it's more complex           |
+|                       | (see examples bellow).                              |
++-----------------------+-----------------------------------------------------+
+| **File fields**       | Only available with ``-f`` / ``--form``. Use ``@``  |
+| ``field@/dir/file``   | as the separator, e.g.,                             |
+|                       | ``screenshot@~/Pictures/img.png``.                  |
+|                       | The presence of a file field results                |
+|                       | into a ``multipart/form-data`` request.             |
++-----------------------+-----------------------------------------------------+
+| **Query string        | Appends the given name/value pair as a query        |
+| parameters**          | string parameter to the URL.                        |
+| ``name==value``       | The ``==`` separator is used                        |
++-----------------------+-----------------------------------------------------+
+
+
+All ``items`` come after the URL, and, unlike ``flags``, they become part of
+the actual request being is sent. Their types are distinguished by the
+separator used.
+
+
+Examples
+--------
+::
+
+    http PATCH api.example.com/person/1 X-API-Token:123 name=John email=john@example.org age:=29
+
+The following request is issued::
+
+    PATCH /person/1 HTTP/1.1
+    User-Agent: HTTPie/0.1
+    X-API-Token: 123
+    Content-Type: application/json; charset=utf-8
+
+    {"name": "John", "email": "john@example.org", "age": 29}
+
+It can easily be changed to a **form** request using the ``-f``
+(or ``--form``) flag, which produces::
+
+    PATCH /person/1 HTTP/1.1
+    User-Agent: HTTPie/0.1
+    X-API-Token: 123
+    Content-Type: application/x-www-form-urlencoded; charset=utf-8
+
+    age=29&name=John&email=john%40example.org
+
+It is also possible to send ``multipart/form-data`` requests, i.e., to
+simulate a **file upload form** submission. It is done using the
+``--form`` / ``-f`` flag and passing one or more file fields::
+
+    http -f POST example.com/jobs name=John cv@~/Documents/cv.pdf
+
+The above will send the same request as if the following HTML form were
+submitted::
+
+    <form enctype="multipart/form-data" method="post" action="http://example.com/jobs">
+        <input type="text" name="name" />
+        <input type="file" name="cv" />
+    </form>
+
+**Query string parameters** can be added to any request without having to
+escape the ``&`` characters. The following request will contain
+``?search=donuts&in=fridge`` as the query string part of the URL::
+
+    http GET example.com search==donuts in==fridge
+
+The whole request body can also be passed in **via stdin,** in which
+case it will be used with no further processing::
+
+    echo '{"name": "John"}' | http PATCH example.com/person/1 X-API-Token:123
+    # Or:
+    http POST example.com/person/1 X-API-Token:123 < person.json
+
+That can be used for **piping services together**. The following example
+``GET``-s JSON data from the Github API and ``POST``-s it to httpbin.org::
+
+    http GET https://api.github.com/repos/jkbr/httpie | http POST httpbin.org/post
+
+The above can be further simplified by omitting ``GET`` and ``POST`` because
+they are both default here as the first command has no request data whereas
+the second one has via ``stdin``::
+
+    http https://api.github.com/repos/jkbr/httpie | http httpbin.org/post
+
+Note that when the **output is redirected** (like the examples above), HTTPie
+applies a different set of defaults than for a console output. Namely, colors
+aren't used (unless ``--pretty`` is set) and only the response body
+is printed (unless ``--print`` options specified).
+
+An alternative to ``stdin`` is to pass a filename whose content will be used
+as the request body. It has the advantage that the ``Content-Type`` header
+will automatically be set to the appropriate value based on the filename
+extension. Thus, the following will request will send the verbatim contents
+of the file with ``Content-Type: application/xml``::
+
+    http PUT httpbin.org/put @/data/file.xml
+
+When using HTTPie from **shell scripts** it can be useful to use the
+``--check-status`` flag. It instructs HTTPie to exit with an error if the
+HTTP status is one of ``3xx``, ``4xx``, or ``5xx``. The exit status will
+be ``3`` (unless ``--allow-redirects`` is set), ``4``, or ``5``,
+respectively::
+
+    #!/bin/bash
+
+    if http --check-status HEAD example.org/health &> /dev/null; then
+        echo 'OK!'
+    else
+        case $? in
+            3) echo 'Unexpected 3xx Redirection!' ;;
+            4) echo '4xx Client Error!' ;;
+            5) echo '5xx Server Error!' ;;
+            *) echo 'Other Error!' ;;
+        esac
+    fi
+
+

+
+    HTTPie - cURL for humans. <http://httpie.org>
+
+    positional arguments:
+      METHOD                The HTTP method to be used for the request (GET, POST,
+                            PUT, DELETE, PATCH, ...). If this argument is omitted,
+                            then HTTPie will guess the HTTP method. If there is
+                            some data to be sent, then it will be POST, otherwise
+                            GET.
+      URL                   The protocol defaults to http:// if the URL does not
+                            include one.
+      ITEM                  A key-value pair whose type is defined by the
+                            separator used. It can be an HTTP header
+                            (header:value), a data field to be used in the request
+                            body (field_name=value), a raw JSON data field
+                            (field_name:=value), a query parameter (name==value),
+                            or a file field (field_name@/path/to/file). You can
+                            use a backslash to escape a colliding separator in the
+                            field name.
+
+    optional arguments:
+      --help                show this help message and exit
+      --version             show program's version number and exit
+      --json, -j            (default) Data items from the command line are
+                            serialized as a JSON object. The Content-Type and
+                            Accept headers are set to application/json (if not
+                            specified).
+      --form, -f            Data items from the command line are serialized as
+                            form fields. The Content-Type is set to application/x
+                            -www-form-urlencoded (if not specified). The presence
+                            of any file fields results into a multipart/form-data
+                            request.
+      --traceback           Print exception traceback should one occur.
+      --pretty              If stdout is a terminal, the response is prettified by
+                            default (colorized and indented if it is JSON). This
+                            flag ensures prettifying even when stdout is

+      --ugly, -u            Do not prettify the response.
+      --print OUTPUT_OPTIONS, -p OUTPUT_OPTIONS
+                            String specifying what the output should contain: "H"
+                            stands for the request headers, and "B" for the
+                            request body. "h" stands for the response headers and
+                            "b" for response the body. The default behaviour is
+                            "hb" (i.e., the response headers and body is printed),
+                            if standard output is not redirected. If the output is

+                            solarized. For this option to work properly, please
+                            make sure that the $TERM environment variable is set
+                            to "xterm-256color" or similar (e.g., via `export TERM
+                            =xterm-256color' in your ~/.bashrc).
+      --check-status        By default, HTTPie exits with 0 when no network or
+                            other fatal errors occur. This flag instructs HTTPie
+                            to also check the HTTP status code and exit with an
+                            error if the status indicates one. When the server
+                            replies with a 4xx (Client Error) or 5xx (Server
+                            Error) status code, HTTPie exits with 4 or 5
+                            respectively. If the response is a 3xx (Redirect) and
+                            --allow-redirects hasn't been set, then the exit
+                            status is 3. Also an error message is written to
+                            stderr if stdout is redirected.
+      --auth AUTH, -a AUTH  username:password. If only the username is provided
+                            (-a username), HTTPie will prompt for the password.
+      --auth-type {basic,digest}
+                            The authentication mechanism to be used. Defaults to
+                            "basic".
+      --verify VERIFY       Set to "no" to skip checking the host's SSL
+                            certificate. You can also pass the path to a CA_BUNDLE
+                            file for private certs. You can also set the
+                            REQUESTS_CA_BUNDLE environment variable. Defaults to
+                            "yes".
+      --proxy PROXY         String mapping protocol to the URL of the proxy (e.g.
+                            http:foo.bar:3128).
+      --allow-redirects     Set this flag if full redirects are allowed (e.g. re-
+                            POST-ing of data at new ``Location``)
+      --timeout TIMEOUT     Float describes the timeout of the request (Use
+                            socket.setdefaulttimeout() as fallback).
+
+
+Contribute
+==========
+
+Bug reports and code and documentation patches are greatly appretiated. You can
+also help by using the development version of HTTPie and reporting any bugs you
+might encounter.
+
+Before working on a new feature or a bug, please browse the `existing issues`_
+to see whether it has been previously discussed.
+
+Then fork and clone `the repository`_.
+
+To point the ``http`` command to your local branch during development you can
+install HTTPie in an editable mode::
+
+    pip install --editable .
+
+To run the existing suite of tests before a pull request is submitted::
+
+    python setup.py test
+
+`Tox`_ can also be used to conveniently run tests in all of the
+`supported Python environments`_::
+
+    # Install tox
+    pip install tox
+
+    # Run tests
+    tox
+
+
+Changelog
+=========
+
+* `0.2.7dev`_
+* `0.2.6`_ (2012-07-26)
+    * The short option for ``--headers`` is now ``-h`` (``-t`` has been
+      removed, for usage use ``--help``).
+    * Form data and URL parameters can have multiple fields with the same name
+      (e.g.,``http -f url a=1 a=2``).
+    * Added ``--check-status`` to exit with an error on HTTP 3xx, 4xx and
+      5xx (3, 4, and 5, respectively).
+    * If the output is piped to another program or redirected to a file,
+      the default behaviour is to only print the response body.
+      (It can still be overwritten via the ``--print`` flag.)
+    * Improved highlighting of HTTP headers.
+    * Added query string parameters (``param==value``).
+    * Added support for terminal colors under Windows.
+* `0.2.5`_ (2012-07-17)
+    * Unicode characters in prettified JSON now don't get escaped for
+      improved readability.
+    * --auth now prompts for a password if only a username provided.
+    * Added support for request payloads from a file path with automatic
+      ``Content-Type`` (``http URL @/path``).
+    * Fixed missing query string when displaying the request headers via
+      ``--verbose``.
+    * Fixed Content-Type for requests with no data.
+* `0.2.2`_ (2012-06-24)
+    * The ``METHOD`` positional argument can now be omitted (defaults to
+      ``GET``, or to ``POST`` with data).
+    * Fixed --verbose --form.
+    * Added support for `Tox`_.
+* `0.2.1`_ (2012-06-13)
+    * Added compatibility with ``requests-0.12.1``.
+    * Dropped custom JSON and HTTP lexers in favor of the ones newly included
+      in ``pygments-1.5``.
+* `0.2.0`_ (2012-04-25)
+    * Added Python 3 support.
+    * Added the ability to print the HTTP request as well as the response
+      (see ``--print`` and ``--verbose``).
+    * Added support for Digest authentication.
+    * Added file upload support
+      (``http -f POST file_field_name@/path/to/file``).
+    * Improved syntax highlighting for JSON.
+    * Added support for field name escaping.
+    * Many bug fixes.
+* `0.1.6`_ (2012-03-04)
