ivydepparse.py - Ivy Dependency Parser

Parsing an Ivy module descriptor (ivy.xml) for its dependencies from a tool like CMake can be tough. This script takes a descriptor on the standard input and prints its dependencies in an easily parsable format.

Installation

$ sudo pip install ivydepparse

Usage

$ ivydepparse < ivy.xml

Example

ivy-example.xml:

...
    <dependency org="com.ttgf" name="myGreatDep" rev="1.2.3" conf="debug;release"/>
    <dependency org="com.ttgf" name="myGreatDep" rev="1.2.3" conf="other"/>
    <dependency org="com.ttgf" name="myGreatDebugDep" rev="2.3.4" conf="debug"/>
...

results in

$ ivydepparse < ivy-example.xml
org=com.ttgf|name=myGreatDebugDep|rev=2.3.4|conf=debug;org=com.ttgf|name=myGreatDep|rev=1.2.3|conf=debug,release,other

Details

The output is a one-liner, a semicolon-separated list of dependencies. Each dependency is a pipe-separated list of attributes as name=value.

If any value contains one of our separators, they get escaped as follows:

• ; is replaced by ,
• | is replaced by :
• = is replaced by :

For each dependency, all attributes are guaranteed to be present and in that order: org, name, rev, conf.

Attributes can be empty. An empty attribute appears as name=.

Dependencies having the same key (org/name/rev) will be output as one single dependency.

The order inside conf in the output is not specified.

The order of the dependencies in the output is not specified.
