1. An ASL Appetizer
ASL!

2. Overview
What is ASL?
What can I do with ASL?
Demo

3. What is ASL? Adapter Scripting Language Not a general purpose language
Limited I/O (no user interaction)
No library support
The native scripting language of InCharge

4. Unique Strengths of ASL
A Parser
Makes it easy to parse files of any format
As powerful as regular expressions but easier to read!
Can connect two InCharge processes
Many built in connections are implemented in ASL
Embedded in all of the InCharge binaries
Runs inside of an InCharge server
Always available in any InCharge environment

5. InCharge Binary What are the InCharge binaries? sm_server SAM IP AM/PM
NPM
sm_adapter
Syslog Adapter
EMOM Adapter
sm_trapd
Trap Adapter
brstart
Broker

8. What can ASL do?

9. Interact with a remote repository
Server API
Repos
sm_whatever…
sm_adapter –s REMOTE_SERVER
Client API
routers = getInstances(“Router”);
foreach r (routers) {
rObj = object(“Router”, r); }
Server
Client

10. Interact with the local repository
Server API
Repos
sm_whatever…
sm_adapter
Client API
routers = self->getInstances(“Router”);
foreach r (routers) {
rObj = self->object(“Router”, r); }

11. Subscribe to Topology and/or Events
Server API
Repos
sm_whatever…
sm_adapter –-subscribe=.*::.*::.*/pae
Client API
START {
timeStamp : integer fs
“NOTIFY” fs
class : word fs
instance : word fs
event : word fs
conf : integer fs }
Server
Client

12. Read/Parse a file sm_whatever… Server API Repos Client API
sm_adapter --file=jdr.txt
Client API
START {
h : word
c : word
..eol
} do {
adp->addPending(h,c,”Read from file”); }
plan_r.afnoc.mil poe
fluid.gnt.mil poe
essence.brk.mil poe

13. Write to a file sm_whatever… Server API Repos Client API
sm_adapter –m sm_actions
Client API
fo = create(“ACT_File”, “myFileObj”);
Fo->fileName = “myAdapter.log”;
foreach n (getInstances(“Node”) {
obj = object(n);
fo->writeln(obj->CreatonClass.”\t”.n); }
Router gw1-i-fw-001
Host im2-i-fms-001

14. Launch other ASL threads
Server API
Repos
sm_whatever…
Client API
drv = create(“GA_Driver”, “myDrv”);
drv->ReadsRulesFrom = create(“GA_RuleSet, “myRules”);
drv->ReadsRulesFrom->fileName=“foo.asl”;
drv->start();
