Padre::Util − Padre non−Wx Utility Functions
The "Padre::Util" package is a internal storage area for miscellaneous functions that aren’t really Padre-specific that we want to throw somewhere convenient so they won’t clog up task-specific packages.
All functions are exportable and documented for maintenance purposes, but except for in the Padre core distribution you are discouraged in the strongest possible terms from using these functions, as they may be moved, removed or changed at any time without notice.
"slurp"
my $content = Padre::Util::slurp( $file );
if ( $content ) {
print $$content;
} else {
# Handle errors appropriately
}
This is a simple slurp implementation, provided as a convenience for internal Padre use when loading trivial unimportant files for which we don’t need anything more robust.
All file reading is done with "binmode" enabled, and data is returned by reference to avoid needless copying.
Returns the content of the file as a SCALAR reference if the file exists and can be read.
Returns false if loading of the file failed.
This function is only expected to be used in situations where the file should almost always exist, and thus the reason why reading the file failed isn’t really important.
"newline_type"
my $type = Padre::Util::newline_type( $string );
Returns "None" if there was not "CR" or "LF" in the file.
Returns "UNIX", "Mac" or "Windows" if only the appropriate newlines were found.
Returns "Mixed" if line endings are mixed.
"get_matches"
Parameters:
|
• |
The text in which we need to search |
||
|
• |
The regular expression |
||
|
• |
The offset within the text where we the last match started so the next forward match must start after this. |
||
|
• |
The offset within the text where we the last match ended so the next backward match must end before this. |
||
|
• |
backward bit (1 = search backward, 0 = search forward) − Optional. Defaults to 0. |
"_T"
The "_T" function is used for strings that you do not want to translate immediately, but you will be translating later (multiple times).
The only reason this function needs to exist at all is so that the translation tools can identify the string it refers to as something that needs to be translated.
Functionally, this function is just a direct pass-through with no effect.
"share"
If called without a parameter returns the share directory of Padre. If called with a parameter (e.g. "Perl6") returns the share directory of Padre::Plugin::Perl6
"get_project_rcs"
Given a project directory (see "get_project_dir"), returns the project’s Revision Control System ("RCS") by name. This can be either "CVS", "SVN" or "Git". Returns "undef" if none was found.
"get_project_dir"
Given a file it will try to locate the root directory of the given project. This is a temporary work around till we get full project support but it is used by some ("SVK") plug-ins.
"parse_version"
This is a clone of ExtUtils::MakeMaker "parse_version" to prevent loading a bunch of other modules
my $version = Padre::Util::parse_version($file);
Parse a $file and return what $VERSION is set to by the first assignment. It will return the string "undef" if it can’t figure out what $VERSION is. $VERSION should be for all to see, so "our $VERSION" or plain $VERSION are okay, but "my $VERSION" is not.
"parse_version()" will try to "use version" before checking for $VERSION so the following will work.
$VERSION = qv(1.2.3);
