.heuristic_parse(uri) ⇒ Gitable::URI?

Attempts to make a copied URL bar into a git repository URI.

First line of defense is for URIs without .git as a basename:

  • Change the scheme from http:// to git://

  • Add .git to the basename

Parameters:

  • uri (Addressable::URI, #to_str) —

    URI of a git repository.

Returns:

  • (Gitable::URI, nil) —

    the URI object or nil if nil was passed in.

Raises:

  • (TypeError) —

    The uri must respond to #to_str.

  • (Gitable::URI::InvalidURIError) —

    When the uri is total rubbish.

def self.heuristic_parse(uri)
  return uri if uri.nil? || uri.kind_of?(self)

  # Addressable::URI.heuristic_parse _does_ return the correct type :)
  gitable = super # boo inconsistency

  if gitable.github?
    gitable.extname = "git"
  end
  gitable
end

.parse(uri) ⇒ Gitable::URI?

Parse a git repository URI into a URI object.

Parameters:

  • uri (Addressable::URI, #to_str) —

    URI of a git repository.

Returns:

  • (Gitable::URI, nil) —

    the URI object or nil if nil was passed in.

Raises:

  • (TypeError) —

    The uri must respond to #to_str.

  • (Gitable::URI::InvalidURIError) —

    When the uri is total rubbish.

  add = super # >:( at inconsistency

  if Gitable::ScpURI.scp?(uri)
    # nil host is an Addressable misunderstanding (therefore it might be scp style)
    Gitable::ScpURI.parse(uri)

Instance Method Details

#authenticated? ⇒ Boolean

Detect URIs that will require some sort of authentication

Returns:

  • (Boolean) —

    true if the URI uses ssh or has a user but no password

# File 'lib/gitable/uri.rb', line 109

def authenticated?
  ssh? || (!normalized_user.nil? && normalized_password.nil?)
end

#basename ⇒ Object

Addressable does basename wrong when there’s no basename. It returns “/” for something like “host.com/”

141
142
 
# File 'lib/gitable/uri.rb', line 140

def basename
  super == "/" ? "" : super
end

#basename=(new_basename) ⇒ String

Set the basename, replacing it if it exists.

Parameters:

  • New (String) —

    basename

Returns:

  • (String) —

    basename result

# File 'lib/gitable/uri.rb', line 148

def basename=(new_basename)
  base = basename
  if base.to_s.empty?
    self.path += new_basename
  else
    rpath = normalized_path.reverse
    # replace the last occurrence of the basename with basename.ext
    self.path = rpath.sub(%r|#{Regexp.escape(base.reverse)}|, new_basename.reverse).reverse
  end
  basename
end

#extname=(new_ext) ⇒ String

Set an extension name, replacing one if it exists.

If there is no basename (i.e. no words in the path) this method call will be ignored because it is likely to break the uri.

Use the public method #set_git_extname unless you actually need some other ext

Parameters:

  • New (String) —

    extension name

Returns:

  • (String) —

    extname result

  return nil if basename.to_s.empty?
  self.basename = "#{basename.sub(%r#\.git/?$#, '')}.#{new_ext.sub(/^\.+/,'')}"
  extname
end

#github? ⇒ Boolean

Is this uri a github uri?

Returns:

  • (Boolean) —

    github.com is the host?



59

61
 
# File 'lib/gitable/uri.rb', line 59

def github?
  !!normalized_host.to_s.match(/\.?github.com$/)
end

#inferred_scheme ⇒ Boolean

Scheme inferred by the URI (URIs without hosts or schemes are assumed to be ‘file’)

Returns:

  • (Boolean) —

    Is the URI local

    'file'
  else
    normalized_scheme
  end
end

#local? ⇒ Boolean

Detect local filesystem URIs.

Returns:

  • (Boolean) —

    Is the URI local



84
85
86
 
# File 'lib/gitable/uri.rb', line 84

def local?
  inferred_scheme == 'file'
end

#project_name ⇒ String

Tries to guess the project name of the repository.

Returns:

  • (String) —

    Project name without .git



77
78
79
 
# File 'lib/gitable/uri.rb', line 77

def project_name
  basename.sub(/\.git$/,'')
end

#set_git_extname ⇒ String

Set the ‘.git’ extension name, replacing one if it exists.

If there is no basename (i.e. no words in the path) this method call will be ignored because it is likely to break the uri.

Returns:

  • (String) —

    extname result

# File 'lib/gitable/uri.rb', line 134

def set_git_extname
  self.extname = "git"
end

#ssh? ⇒ Boolean

Detect URIs that connect over ssh

Returns:

  • (Boolean) —

    true if the URI uses ssh?



102
103
104
 
# File 'lib/gitable/uri.rb', line 102

def ssh?
  !!normalized_scheme.to_s.match(/ssh/)
end

#to_web_uri(uri_scheme = 'https') ⇒ Addressable::URI

Create a web uri for repositories that follow the github pattern. This probably won’t work for all git hosts, so it’s a good idea to use this in conjunction with #github? to help ensure correct links.

Parameters:

  • Scheme (String) —

    of the web uri (smart defaults)

Returns:

  • (Addressable::URI) —

    https://#host/#path_without_git_extension

  return nil if normalized_host.to_s.empty?
  Addressable::URI.new(:scheme => uri_scheme, :host => normalized_host, :port => normalized_port, :path => normalized_path.sub(%r#\.git/?#, ''))
end
