NAME¶
scandeps - Scan file prerequisites
SYNOPSIS¶
% scandeps *.pm # Print PREREQ_PM section for *.pm
% scandeps -e 'STRING' # Scan an one-liner
% scandeps -B *.pm # Include core modules
% scandeps -V *.pm # Show autoload/shared/data files
% scandeps -R *.pm # Don't recurse
% scandeps -C CACHEFILE # use CACHEFILE to cache dependencies
DESCRIPTION¶
scandeps is a simple-minded utility that prints out the
"PREREQ_PM" section needed by modules.
If you have
CPANPLUS installed, modules that are part of an earlier
module's distribution with be denoted with "S"; modules without a
distribution name on CPAN are marked with "?".
Also, if the "-B" option is specified, module belongs to a perl
distribution on CPAN (and thus uninstallable by "CPAN.pm" or
"CPANPLUS.pm") are marked with "C".
Finally, modules that has loadable shared object files (usually needing a
compiler to install) are marked with "X"; with the "-V"
flag, those files (and all other files found) will be listed before the main
output. Additionally, all module files that the scanned code depends on but
were not found (and thus not scanned recursively) are listed. These may
include genuinely missing modules or false positives. That means, modules your
code does not depend on (on this particular platform) but that were picked up
by the heuristic anyway.
OPTIONS¶
- -e STRING
- Scan STRING as a string containing perl code.
- -c
- Compiles the code and inspects its %INC, in addition to
static scanning.
- -x
- Executes the code and inspects its %INC, in addition to
static scanning.
- -B
- Include core modules in the output and the recursive search
list.
- -R
- Only show dependencies found in the files listed and do not
recurse.
- -V
- Verbose mode: Output all files found during the process;
show dependencies between modules and availability.
Additionally, warns of any missing dependencies. If you find missing
dependencies that aren't really dependencies, you have probably found
false positives.
- -C CACHEFILE
- Use CACHEFILE to speed up the scanning process by caching
dependencies. Creates CACHEFILE if it does not exist yet.
