# clj-dde

A Clojure library (really a wrapper around the Java DDE library provided by pretty_tools) to interoperate with DDE (dynamic data exchange) sources.

## Rationale

1. Sometimes you need to connect to a DDE source, and

2. would rather do it in Clojure > some other language

## Setup

Make sure you have [Leiningen](http://leiningen.org/) installed.

Your `project.clj` should include something like the following:

```clj

(defproject foo "0.1.0"

  ...

  :dependencies [[org.clojure/clojure "1.5.1"]

                 [clj-dde "0.2.0"]]

  ...)

```

## Usage

Work in Progress.

When you need to connect with a DDE data source...

```clojure

(def excel-conv (dde/convesation))          ;; to setup a connection.

(dde/connect excel-conv "excel" "sheet1")   ;; to connect to a datasource (excel)

(dde/request excel-conv "R1C1")             ;; to 'poll' the data contained in cell R1C1

```

The major difference between version 0.1.x and 0.2.x is that all functions

that previously returned `nil` now returns the conversation object, thus

making the functions chain-able:

```clojure

(-> (dde/conversation)

    (dde/connect "excel" "sheet1")

    (dde/request "R1C1"))

```

check out the dde-example folder for further examples and usage.

## Issues

If you get the message "java.lang.UnsatisfiedLinkError: no JavaDDEx64 (or JavaDDE) in java.library.path"  you need to add the javaDDEx64.dll (or javaDDE.dll) file (it's in /resources) to your classpath directory:

`(System/getProperty "java.library.path")` to find out where this file needs to go.
