Filename suffix mappings for compression formats
------------------------------------------------
Key: COMPRESS-68
URL: https://issues.apache.org/jira/browse/COMPRESS-68
Project: Commons Compress
Issue Type: New Feature
Reporter: Jukka Zitting
Priority: Minor
There are many file name suffix conventions like .tgz for gzipped .tar files
and .svgz for gzipped .svg files. It would be useful if Commons Compress knew
about these conventions and provided tools to help client applications to use
these conventions.
For example in Apache Tika we currently have the following custom code to
deduce the original filename from a gzipped file:
{code}
if (name.endsWith(".tgz")) {
name = name.substring(0, name.length() - 4) + ".tar";
} else if (name.endsWith(".gz") || name.endsWith("-gz")) {
name = name.substring(0, name.length() - 3);
} else if (name.toLowerCase().endsWith(".svgz")) {
name = name.substring(0, name.length() - 1);
} else if (name.toLowerCase().endsWith(".wmz")) {
name = name.substring(0, name.length() - 1) + "f";
} else if (name.toLowerCase().endsWith(".emz")) {
name = name.substring(0, name.length() - 1) + "f";
}
{code}
It would be nice if we instead could do something like this:
{code}
name = GzipUtils.getGunzipFilename(name);
{code}
