OVERVIEW
--------
The cvs DCOP service consists of the following three parts:
1. CvsService - The main interface to the functionality of the cvs command line
client. There is one method for each cvs command, e.g. add,
checkout, commit, etc... The methods assemble the command line
arguments, create a CvsJob and return a DCOPRef object for it
to the caller. There is one instance of this service for each
application instance.
2. Repository - This DCOPObject manages the configuration data of the current
cvs repository. The data is automatically updated when other
service instances change it.
3. CvsJob - This class represents a cvs job. You can execute and cancel it,
and you can retrieve the output of the cvs client by either
connecting to the proper DCOP Q_SIGNALS or by using the output()
method. There are two types of jobs. First the non-concurrent
job which has to run alone, like cvs update or import. Second
the jobs which can run concurrently like cvs log or annotate.
USAGE
-----
How-to use this service in C++ applications:
// start DCOP service
QString error;
QCString appId;
KApplication::startServiceByDesktopName("cvsservice", QStringList(), &error,
&appId);
// create stub for repository
Repository_stub repository(appId, "CvsRepository");
// set directory of working copy
repository.setWorkingCopy("/home/user/kde/kdesdk/cervisia");
// create stub for service
CvsService_stub cvsService(appId, "CvsService");
// call "cvs log" for cervisiapart.h
DCOPRef job = cvsService.log("cervisiapart.h");
// connect to Q_SIGNALS to get output
connectDCOPSignal(job.app(), job.obj(), "jobExited(bool, int)", [MY SLOT]);
connectDCOPSignal(job.app(), job.obj(), "receivedStdout(QString)",
[MY SLOT]);
// execute the cvs command
job.execute();
How-to use this service in a shell script:
#!/bin/sh
# start DCOP service
APP=`dcopstart cvsservice`
# set directory of working copy
dcop $APP CvsRepository setWorkingCopy /home/user/kde/kdesdk/cervisia
# call "cvs log" for cervisiapart.h
JOB=`dcop $APP CvsService log cervisiapart.h`
# execute the cvs command
dcop $JOB execute
# print the output on stdout
dcop $JOB output
# stop DCOP service
dcop $APP CvsService quit
How-to use this service in a javascript:
#!/usr/bin/env kjscmd
var client = new DCOPClient(this);
if ( client.attach() )
{
// start DCOP service
var appID = client.dcopStart("cvsservice");
// set directory of working copy
client.send(appID, "CvsRepository", "setWorkingCopy(QString)", "/home/user/kde/kdesdk/cervisia");
// call "cvs log" for cervisiapart.h
var job = client.call(appID, "CvsService", "log(QString)", "cervisiapart.h");
// execute the cvs command
job.call("execute()");
// wait for job to finish
while( job.call("isRunning()") );
// print the output on stdout
var output = job.call("output()");
println(output);
// stop DCOP service
client.send(appID, "CvsService", "quit()");
}
