2.7. Conditions
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
in Section 2.1.
3. Responsibilities
-------------------
3.1. Distribution of Source Form
All distribution of Covered Software in Source Code Form, including any
Modifications that You create or to which You contribute, must be under
the terms of this License. You must inform recipients that the Source
Code Form of the Covered Software is governed by the terms of this
License, and how they can obtain a copy of this License. You may not
attempt to alter or restrict the recipients' rights in the Source Code
Form.
3.2. Distribution of Executable Form
If You distribute Covered Software in Executable Form then:
(a) such Covered Software must also be made available in Source Code
Form, as described in Section 3.1, and You must inform recipients of
the Executable Form how they can obtain a copy of such Source Code
Form by reasonable means in a timely manner, at a charge no more
than the cost of distribution to the recipient; and
(b) You may distribute such Executable Form under the terms of this
License, or sublicense it under different terms, provided that the
license for the Executable Form does not attempt to limit or alter
the recipients' rights in the Source Code Form under this License.
3.3. Distribution of a Larger Work
You may create and distribute a Larger Work under terms of Your choice,
provided that You also comply with the requirements of this License for
the Covered Software. If the Larger Work is a combination of Covered
Software with a work governed by one or more Secondary Licenses, and the
Covered Software is not Incompatible With Secondary Licenses, this
License permits You to additionally distribute such Covered Software
under the terms of such Secondary License(s), so that the recipient of
the Larger Work may, at their option, further distribute the Covered
Software under the terms of either this License or such Secondary
License(s).
3.4. Notices
You may not remove or alter the substance of any license notices
(including copyright notices, patent notices, disclaimers of warranty,
or limitations of liability) contained within the Source Code Form of
the Covered Software, except that You may alter any license notices to
the extent required to remedy known factual inaccuracies.
3.5. Application of Additional Terms
You may choose to offer, and to charge a fee for, warranty, support,
indemnity or liability obligations to one or more recipients of Covered
Software. However, You may do so only on Your own behalf, and not on
behalf of any Contributor. You must make it absolutely clear that any
such warranty, support, indemnity, or liability obligation is offered by
You alone, and You hereby agree to indemnify every Contributor for any
liability incurred by such Contributor as a result of warranty, support,
indemnity or liability terms You offer. You may include additional
disclaimers of warranty and limitations of liability specific to any
jurisdiction.
4. Inability to Comply Due to Statute or Regulation
---------------------------------------------------
If it is impossible for You to comply with any of the terms of this
License with respect to some or all of the Covered Software due to
statute, judicial order, or regulation then You must: (a) comply with
the terms of this License to the maximum extent possible; and (b)
describe the limitations and the code they affect. Such description must
be placed in a text file included with all distributions of the Covered
Software under this License. Except to the extent prohibited by statute
or regulation, such description must be sufficiently detailed for a
recipient of ordinary skill to be able to understand it.
5. Termination
--------------
5.1. The rights granted under this License will terminate automatically
if You fail to comply with any of its terms. However, if You become
compliant, then the rights granted under this License from a particular
Contributor are reinstated (a) provisionally, unless and until such
Contributor explicitly and finally terminates Your grants, and (b) on an
ongoing basis, if such Contributor fails to notify You of the
non-compliance by some reasonable means prior to 60 days after You have
come back into compliance. Moreover, Your grants from a particular
Contributor are reinstated on an ongoing basis if such Contributor
notifies You of the non-compliance by some reasonable means, this is the
first time You have received notice of non-compliance with this License
from such Contributor, and You become compliant prior to 30 days after
Your receipt of the notice.
5.2. If You initiate litigation against any entity by asserting a patent
infringement claim (excluding declaratory judgment actions,
counter-claims, and cross-claims) alleging that a Contributor Version
directly or indirectly infringes any patent, then the rights granted to
You by any and all Contributors for the Covered Software under Section
2.1 of this License shall terminate.
5.3. In the event of termination under Sections 5.1 or 5.2 above, all
end user license agreements (excluding distributors and resellers) which
have been validly granted by You or Your distributors under this License
prior to termination shall survive termination.

# vertx-clojure
A lightweight clojure adapter for vertx toolkit.
- **STATUS**: *alpha*, in design and prototyping phase.
- **AUDIENCE**: this is not a vertx documentation, this readme intends
to explain only the clojure api
Example code on `resources/user.clj` file.
## Install
Using `deps.edn`:
```clojure
vertx-clojure/vertx {:mvn/version "0.0.0-SNAPSHOT"}
```
Using Leiningen:
```clojure
[vertx-clojure/vertx "0.0.0-SNAPSHOT"]
```
## User Guide
### Verticles
Verticles is the basic "unit of execution" in the vertx toolkit. The
concept is very simular to actors with the exception that a verticle
does not have a inbox, and verticles communicates with other verticles
or with the rest of the world using **eventbus**.
For create a verticle, you will need to create first a system instance
(a name that we give to the `Vertx` instance):
```clojure
(require '[vertx.core :as vc])
(def system (vc/system))
```
Then, you can proceed to create a verticle. A verticle concist on
three functions: `on-start`, `on-stop` and `on-error` (where the
`on-start` is mandatory the rest optional).
Lets define a dummy verticle that just prints hello world on start
callback:
```clojure
(defn on-start
[ctx]
(println "Hello world"))
(def dummy-verticle
(vc/verticle {:on-start on-start}))
```
The `dummy-verticle` is a verticle factory, nothing is running at this
momment. For run the verticle we need to deploy it using the
previously created `system` instance:
```clojure
(vc/deploy! system dummy-verticle)
```
The `deploy!` return value is a `CompletionStage` so you can deref it
like a regular `Future` or use **funcool/promesa** for chain more
complex transformations. The return value implements `AutoCloseable`
that will allow to undeploy the verticle.
The `deploy!` function also accepts an additional parameter for
options, and at this momment it only accepts as single option:
- `:instances` - number of instances to launch of the same verticle.
### Event Bus
The **eventbus** is the central communication system for verticles. It
has different patterns of communication. On this documentation we will
cover the: `publish/subscribe` and `request/reply`.
Lets define a simple echo verticle:
```clojure
(require '[vertx.eventbus :as ve])
(defn on-message
[msg]
(:body msg))
(defn on-start
[ctx]
(vc/consumer ctx "test.echo" on-message))
(def echo-verticle
(vc/verticle {:on-start on-start}))
```
And then, lets deploy 4 instances of it:
```clojure
(vc/deploy! system echo-verticle {:instances 4})
```
Now, depending on how you send the messages to the "test.echo" topic,
the message will be send to a single instance of will be broadcasted
to all verticle instances subscribed to it.
To send a message and expect a response we need to use the
`ve/request!` function:
```clojure
@(ve/request! system {:foo "bar"})
;; => #vertx.eventbus.Msg{:body {:foo "bar"}}
```
The return value of `on-message` callback will be used as a reply and
it can be any plain value or a `CompletionStage`.
When you want to send a message but you don't need the return value,
there is the `ve/send!` function. And finally, if you want to send a
message to all instances subscribed to a topic, you will need to use
the `ve/publish!` function.
### Http Server (vertx.http)
**STATUS**: pre-alpha: experimental & incomplete
This part will explain the low-level api for the http server. It is
intended to be used as a building block for a more higher-level api or
when you know that you exactly need for a performance sensitive
applications.
The `vertx.http` exposes two main functions `handler` and
`server`. Lets start creating a simple "hello world" http server:
```
(require '[vertx.http :as vh])
(defn hello-world-handler
[req]
{:status 200
:body "Hello world\n"})
(defn on-start
[ctx]
(vh/server {:handler (vh/handler hello-world-handler)
:port 2021}))
(->> (vc/verticle {:on-start on-start})
(vc/deploy! system))
```
NOTE: you can start the server without creating a verticle but you
will loss the advantage of scaling (using verticle instances
parameter).
The `req` object is a plain map with the following keys:
- `:method` the HTTP method.
- `:path` the PATH of the requested URI.
- `:headers` a map with string lower-cased keys of headers.
- `:vertx.http/request` the underlying vertx request instance.
- `:vertx.http/response` the underlying vertx response instance.
And the response object to the ring response, it can contain
`:status`, `:body` and `:headers`.
**WARNING:** at this moment there are no way to obtain directly the
body of request using clojure api, this is in **design** phase and we
need to think how to expose it correctly without constraint too much
the user code (if you have suggestions, please open an issue).
**NOTE**: If you want completly bypass the clojure api, pass a vertx
`Handler` instance to server instead of using
`vertx.http/handler`. There is the `vertx.util/fn->handler` helper
that converts a plain clojure function into raw `Handler` instance.
### Web Server (vertx.web)
**STATUS**: alpha
This part will explain the higher-level http/web server api. It is a
general purpose with more clojure friendly api. It uses
`reitit-core`for the routing and `sieppari` for interceptors.
Lets start with a complete example:
```clojure
(require '[vertx.http :as vh])
(require '[vertx.web :as vw])
(require '[vertx.web.interceptors :as vwi])
(defn hello-world-handler
[req]
{:status 200
:body "Hello world!\n"})
(defn on-start
[ctx]
(let [routes [["/" {:interceptors [(vwi/cookies)]
:all hello-world-handler}]]
handler (vw/handler ctx
(vw/assets "/static/*" {:root "resources/public/static"})
(vw/router routes))]
(vh/server {:handler handler
:port 2022})))
(->> (vc/verticle {:on-start on-start})
(vc/deploy! system))
```
The routes are defined using `reitit-core` and the interceptors are
using `sieppari` as underlying implementation. The request object is
very similar to the one explained in `vertx.http`.
The main difference with `vertx.http` is that the handler is called
when the body is ready to be used and is available under `:body`
keyword on the request.
All additional features such that reading the query/form params,
parse/write cookies, cors and file uploads are provided with
interceptors as pluggable pieces:
- `vertx.web.interceptors/uploads` parses the vertx uploaded file data
structure and expose it as clojure maps under `:uploads` key.
- `vertx.web.interceptors/params` parses the query string and form
params in the body if the content-type is appropriate and exposes
them under `:params`.
- `vertx.web.interceptors/cors` properly sets the CORS headers.
- `vertx.web.interceptors/cookies` handles the cookies reading from
the request and cookies writing from the response.
