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:

Configure what should be hashed and saved where:

  :files-hash [{:properties-file "resources/versions.properties"
                :property-key "graph-hash"
                :paths ["src/de/otto/package1"
                        "src/de/otto/package2"]}]

This will then on invocation create a SHA-256 Merkle hash tree of all files and their names under the given paths and save the resulting hash 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"]}
