jarfile
A Node.js module for getting information about a jar file.
Synopsis
Want to know something about what is going on in a jar file? This module may help!
Caveats
Currently this module can only tell you about manifest entries. If there's other stuff worth knowing about the contents of a jar file, feel free to submit a pull request!
Installation
npm install jarfile
Example
var jarfile = // Get the Main-Class entry from foo.jar.jarfile
Functions
jarfile.fetchJarAtPath(path, callback)
Reads information from the jar file at the given path, and passes the following to the callback:
- An error if there was an error reading the jar file or its manifest.
- A
Jar
object. See the methods below for what to do with this object.
Note that this function caches Jar
objects and doesn’t make any attempts to ensure the underlying file has not changed.
Jar.prototype.valueForManifestEntry([sectionName], entryName)
Returns the string value for the given entry’s name. If you’re looking for an entry in a particular section, specify the section’s name as the first argument. If the section or entry does not exist in the manifest, null
is returned.
