NAME
Padre::Util - Padre non-Wx Utility Functions
DESCRIPTION
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.
FUNCTIONS
"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.
"parse_variable"
my $version = Padre::Util::parse_variable($file, 'VERSION');
Parse a $file and return what $VERSION (or some other variable) 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_variable()" will try to "use version" before checking for $VERSION so the following will work.
$VERSION = qv(1.2.3);
Originally based on "parse_version" from ExtUtils::MakeMaker.
"_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. Uses File::ShareDir inside.
"run_in_directory"
Padre::Util::run_in_directory( $command, $directory );
Runs the provided "command" in the "directory". On win32 platforms, executes the command to provide *true* background process executions
without window popups on each execution. on non-win32 platforms, it runs a "system" command.
Returns 1 on success and 0 on failure.
"run_in_directory_two"
Plugin replacment for perl command qx{...} to avoid black lines in non *inux os
qx{...};
run_in_directory_two('...');
optional parameters are dir and return type
run_in_directory_two('...', $dir);
run_in_directory_two('...', $dir, type);
also
run_in_directory_two('...', type);
return type 1 default, returns a string
nb you might need to chomp result but thats for you.
return type 0 hash_ref
example 1,
Padre::Util::run_in_directory_two('svn --version --quiet');
"1.6.12
"
example 2,
Padre::Util::run_in_directory_two('svn --version --quiet', 0);
{
error "",
input "svn --version --quiet",
output "1.6.12
"
}
