NAME
Parrot::Configure::Utils - Configuration Step Utilities
DESCRIPTION
The Parrot::Configure::Utils module contains utility functions for use by the configuration step classes found under config/.
The subroutines found in this module do not require the Parrot::Configure object as an argument. Those subroutines formerly found in this module which do require the Parrot::Configure object as an argument have been moved into Parrot::Configure::Compiler.
Functions
_run_command($command, $out, $err)
Runs the specified command.
Output is directed to the file specified by _build_compile_command( $cc, $ccflags, $cc_args )
Constructs a command-line to do the compile.
integrate($orig, $new)
Integrates prompt($message, $value)
Prints out "message [default] " and waits for the user's response.
Returns the response,
or the default if the user just hit file_checksum($filename, $ignore_pattern)
Creates a checksum for the specified file.
This is used to compare files.Any lines matching the regular expression specified by copy_if_diff($from, $to, $ignore_pattern)
Copies the file specified by move_if_diff($from, $to, $ignore_pattern)
Moves the file specified by capture_output($command)
Executes the given command.
The command's output (both stdout and stderr),
and its return status is returned as a 3-tuple.
STDERR is redirected to test.err during the execution,
and deleted after the command's run.
check_progs([$programs])
Where _slurp($filename)
Slurps
$out,
warnings and errors are directed to the file specified by $err.
$new into $orig.
Returns $orig if $new is undefined.
ENTER.
$ignore_pattern are not included in the checksum.
$from to the location specified by $to if its contents have changed.The regular expression specified by $ignore_pattern is passed to file_checksum() when comparing the files.
$from to the location specified by $to if its contents have changed.
$programs may be either a scalar with the name of a single program or an array ref of programs to search the current PATH for.
The first matching program name is returned or undef on failure.
Note: this function only returns the name of the program and not its complete path.This function is similar to autoconf's AC_CHECK_PROGS macro.
$filename into memory and returns it as a string.
This is just an alias for Parrot::BuildUtil::slurp_file.
