BasicUrl

A simple Ruby module that provides basic URL operations.

This implementation supports:

• Object oriented operations (obj.join(component) instead of MODULE.join(obj, component))
• Easy URL encoding
• Joining relative paths (obj('a/b').join('c') returns a/b/c not a/c)

This gem does not try to be RFC compliant when joining URLs.

Given that the majority of other implementations all do some degree of shenanigans when joining URLs it's assumed that a/b/c + d = a/d is buried in a spec somewhere. This library does not do that, it does a/b/c + d = a/b/c/d, which is what is needed in 99% of cases. If you need full RFC compliance this gem is not suitable.

Usage

require 'BasicURL'

base_url = BasicUrl.parse('192.0.2.64/api/v1', default_protocol: 'https')

puts(base_url.path)
# api/v1

# Basic joining, returns a new object
# join! is also available to update the current object
controller = base_url.join('some/controller')
puts controller.path
# api/v1/some/controller

# By default absolute paths replace
controller = base_url.join('/some/controller')
puts controller.path
# some/controller

# But this is selectable
controller = base_url.join('/some/controller', replace_when_absolute: false)
puts controller.path
# api/v1/some/controller             

# To get a URL string call .to_s
puts controller.to_s
# https://192.0.2.64/api/v1/some/controller

# Path components are URL encoded by default
puts BasicUrl.new(protocol: 'http', host: 'foo.local', path: '/api/v0/some path/with spaces', params: { key: 'value:1', key2: 'Value!', key3: ['and', 'arrays']}).to_s
# http://foo.local/api/v0/some+path/with+spaces?key=value%3A1&key2=Value%21&key3[]=and&key3[]=arrays

# Query parameters can also be added with params=.  This modifies the object
controller = base_url.join('some/controller')

controller.params = { key1: 'val1' }
controller.params[:key2] = 'val2'
puts controller.to_s
# https://192.0.2.64/api/v1/some/controller?key1=val1&key2=val2

Contributing

All support is through Github issues. Questions, bug reports and pull requests are accepted at https://github.com/TJNII/basic_url.

This is an opinionated project, the author was finally annoyed enough by using Pathname to join URL components to publish this. This project will not support the a + b + c + d = d behavior of other implementations, if you require that perhaps Adressable::URI would be better.

For the quickest response please add a test case.

Hope this helped you, have a good day.
