dsnparse 0.1.4

parse dsn urls

Parse dsn connection url strings. I kept duplicating dsn parsing code for things like prom and morp, and I realized I was going to need many more dsn urls in the future so I decided to create something a little more modular.

This is a generic version of dj-database-url.

So, now you can create dsns like this:

scheme://user:pass@host:port/path?query=query_val#fragment

For example, let’s look at a prom dsn:

prom.interface.postgres.Interface://testuser:testpw@localhost/testdb

Now let’s parse it:

import dsnparse

dsn = "prom.interface.postgres.Interface://testuser:testpw@localhost:1234/testdb"
r = dsnparse.parse(dsn)

print r.scheme # prom.interface.postgres.Interface
print r.username # testuser
print r.password # testpw
print r.host # localhost
print r.hostloc # localhost:1234
print r.paths # ['testdb']

Also, dsnparse can easily use environment variables:

r = dsnparse.parse_environ('ENVIRONMENT_VARIABLE_NAME')

I tried to keep the interface very similar to urlparse so it will feel familiar to use.
