12 This is a private module for internal use only. There is nothing for
13 you to see here (yet). All API documentation is purely for my own
14 reference.

17 throw($message)
18 throw($exception_object)
19 Throws a Pinto::Exception with the given message. If given a reference
20 to a Pinto::Exception object, then it just throws it again.
21 debug( $message )
23 debug( sub {...} )
24 Writes the message on STDERR if the "PINTO_DEBUG" environment variable
25 is true. If the argument is a subroutine, it will be invoked and its
26 output will be written instead. Always returns true.
27 whine( $message )
29 Just calls warn(), but always appends the newline so that line numbers
30 are suppressed.
31 author_dir( @base, $author )
33 Given the name of an $author, returns the directory where the
34 distributions for that author belong (as a Path::Class::Dir). The
35 optional @base can be a series of Path::Class:Dir or path parts (as
36 strings). If @base is given, it will be prepended to the directory
37 that is returned.
38 itis( $var, $class )
40 Asserts whether var is a blessed reference and is an instance of the
41 $class.
42 parse_dist_path( $path )
44 Parses a path like the ones you would see in a full URI to a
45 distribution in a CPAN repository, or the URI fragment you would see in
46 a CPAN index. Returns the author and file name of the distribution.
47 Subdirectories between the author name and the file name are discarded.
48 isa_perl( $path_or_uri )
50 Return true if $path_or_uri appears to point to a release of perl
51 itself. This is based on some file naming patterns that I've seen in
52 the wild. It may not be completely accurate.
53 mtime( $file )
55 Returns the last modification time (in epoch seconds) for the "file".
56 The argument is required and the file must exist or an exception will
57 be thrown.
58 md5( $file )
60 Returns the "MD-5" digest (as a hex string) for the $file. The
61 argument is required and the file must exist on an exception will be
62 thrown.
63 sha256( $file )
65 Returns the "SHA-256" digest (as a hex string) for the $file. The
66 argument is required and the file must exist on an exception will be
67 thrown.
68 validate_property_name( $prop_name )
70 Throws an exception if the property name is invalid. Currently,
71 property names must be alphanumeric plus any underscores or hyphens.
72 validate_stack_name( $stack_name )
74 Throws an exception if the stack name is invalid. Currently, stack
75 names must be alphanumeric plus underscores or hyphens.
76 current_utc_time()
78 Returns the current time (in epoch seconds) unless the current time has
79 been overridden by $Pinto::Globals::current_utc_time.
80 current_time_offset()
82 Returns the offset between current UTC time and the local time in
83 seconds, unless overridden by $Pinto::Globals::current_time_offset.
84 The "current_time" function is used to determine the current UTC time.
85 current_username()
87 Returns the username of the current user unless it has been overridden
88 by $Pinto::Globals::current_username. The username can be defined
89 through a number of environment variables. Throws an exception if no
90 username can be determined.
91 current_author_id()
93 Returns the author id of the current user unless it has been overridden
94 by $Pinto::Globals::current_author_id. The author id can be defined
95 through environment variables. Otherwise it defaults to the upper-case
96 form of the "current_username". And since PAUSE only allows letters
97 and numbers in the author id, then we remove all of those from the
98 "current_username" too.
99 is_interactive()
101 Returns true if the process is connected to an interactive terminal
102 (i.e. a keyboard & screen) unless it has been overridden by
103 $Pinto::Globals::is_interactive.
104 interpolate($string)
106 Performs interpolation on a literal string. The string should not
107 include anything that looks like a variable. Only metacharacters (like
108 \n) will be interpolated correctly.
109 trim_text($string)
111 Returns the string with all leading and trailing whitespace removed.
112 title_text($string)
114 Returns all the characters in $string before the first newline. If
115 there is no newline, returns the entire $string.
116 body_text($string)
118 Returns all the characters in $string after the first newline. If
119 there is no newline, returns an empty string.
120 truncate_text($string, $length, $elipses)
122 Truncates the $string and appends $elipses if the $string is longer
123 than $length characters. $elipses defaults to '...' if not specified.
124 decamelize($string)
126 Returns the string forced to lower case and words separated by
127 underscores. For example "FooBar" becomes "foo_bar".
128 indent_text($string, $n)
130 Returns a copy of $string with each line indented by $n spaces. In
131 other words, it puts "4n" spaces immediately after each newline in
132 $string. The original $string is not modified.
133 mksymlink($from => $to)
135 Creates a symlink between the two files. No checks are performed to
136 see if either path is valid or already exists. Throws an exception if
137 the operation fails or is not supported.
138 is_system_prop($string)
140 Returns true if $string is the name of a system property.
141 uuid()
143 Returns a UUID as a string. Currently, the UUID is derived from random
144 numbers.
145 user_palette()
147 Returns a reference to an array containing the names of the colors
148 pinto can use. This can be influenced by setting the "PINTO_PALETTE"
149 environment variable.
150 is_blank($string)
152 Returns true if the string is undefined, empty, or contains only
153 whitespace.
154 is_not_blank($string)
156 Returns true if the string contains any non-whitespace characters.
157 mask_uri_passwords($string)
159 Masks the parts the string that look like a password embedded in an
160 http or https URI. For example, "http://joe:secret@foo.com" would
161 return "http://joe:*password*@foo.com"
162 is_remote_repo {
164 Returns true if the argument looks like a URI to a remote repository
