# lein-files-hash

A Leiningen plugin to save hash trees of files and directories to properties

files.

## Usage

Add the dependency to the `:plugins` vector of your project.clj:

[![Clojars Project](http://clojars.org/de.otto/lein-files-hash/latest-version.svg)](http://clojars.org/de.otto/lein-files-hash)

Configure what should be hashed and saved where:

```

  :files-hash [{:properties-file "resources/versions.properties"

                :property-key "graph-hash"

                :deps  ["org.some.dependency/dependency"

                        "org.some.other.dependency/other-dependency"]

                :paths ["src/de/otto/package1"

                        "src/de/otto/package2"]}]

```

This will then on invocation create a SHA-256 Merkle hash tree of all files 

(using filenames under the given paths) and dependencies (using dependency names and 

the corresponding version). The resulting hash is stored under the given

key in the given properties file. As the format hints, you can have multiple

such configurations.  You can also refer to single file names in the paths

vector.

The properties file is read and written through `java.util.Properties` (_not_

`org.apache.commons.configuration.PropertiesConfiguration`!).  This means that

comments are clobbered and in the case of duplicate keys, the last one wins.

Call from shell:

    $ lein files-hash

You might want to do this in your project's build aliases:

    :aliases {"uberjar" ["do" ["clean"] ["files-hash"] "uberjar"]}
