[edit] Papers

These are the papers from talks I have given on D-Bus proper and the Net::DBus binding for perl. They do not differ terribly; The TLUG talk tries to be more language neutral where the TPM talk is more Perl-centric.

• Toronto Perl Mongers (TPM) Talk - Aug. 28, 2008

As: PDF 240 KiB or ODT 94 KiB

• Toronto Linux User's Group (TLUG) Talk - Aug. 12, 2008

As: PDF 248 KiB or ODT 94 KiB (last updated on Aug. 27, 2008)

[edit] Sample Code

These are the sample programs written to go along with the various talks I've given on D-Bus. Each program file has a good deal of internal comments that explain what each part of the various programs does, why it is there and how you might change it to experiment.

[edit] Query HAL for Devices

This is the most basic example of how to use D-Bus. It is a slight modification on the Net::DBus 'lshal.pl' script.

• mk-lshal.pl (Perl 719 bytes)

[edit] Basic Service and Caller

This is a very basic service* script that publishes a simple method onto the D-Bus and a caller that calls the newly published method.

• service_01.pl (Perl 5.8 KiB)
• caller_01.pl (Perl 3.0 KiB)

(* This is not technically a 'service' in the D-Bus sense yet as no '.service' file exists at this point)

[edit] Proper Service script with signals, Updated Caller and new Listener

This is a slightly more advanced version of the previous service script that adds signals onto the D-Bus and a slightly more advanced caller that calls this new signal and a new "listener" file that reacts when the new signal is emitted. This also adds the '.service' file for the service script making it a proper "service" in the D-Bus sense.

• service_01.pl (Perl 6.9 KiB)
• caller_01.pl (Perl 3.6 KiB)
• listener_01.pl (Perl 3.4 KiB)
• tle-bu.org.example_02.service (D-Bus '.service' 159 bytes)

[edit] References

This is the main tutorial page. It still leaves much to be desired.

This is my (Digimer's) personal collection of notes and such that I have gathered while trying to build this body of work.
