Sorry for posting and falling off the earth. A bit sick today but will try and give the gist of a send in time loop. This is just off the top of my head and as always there are probably better ways to do this (also as I mentioned before, not sure which forms of read will block and which won't so your mileage may vary depending on need)
command startProcess ## code to connect to the process open process "myprocess" for update ## check for errors opening the process, if no errors then set the cRunning of this card to true -- a method to break the loop, set to false to stop the loop readloop -- handler to do the read end startProcess command readloop if the the cRunning of this card then read from process "myProcess" until empty if it is not empty then #do whatever you want with the resulting read. #if the end line is read, close process set the cRunning of this card to false end if send "readloop" to me in 1 tick end if end readloop On Wed, Mar 28, 2012 at 4:19 PM, Glen Bojsza <gboj...@gmail.com> wrote: > My first test has come back fairly well. > > I missed some of the initial lines of output but got all the remaining > lines. > > I broke out of the loop no problem with the unique output line... when it > was seen in the output I exited the repeat. > > So the first issue I would like to solve is either have the scrolling field > show the latest output ... how can you have the field show the last ten > lines? > > Optionally, try to figure out a send in time and see if it frees the > user... if it does then this would be the better solution. > > Glen > > On Wed, Mar 28, 2012 at 4:08 PM, Bob Sneidar <b...@twft.com> wrote: > > > One method I have heard of is to redirect output to a text file, then > open > > the file for read and read from the file every so often in a repeat loop. > > You still need to know when the process has ended so you can break out of > > the loop. > > > > Bob > > > > > > On Mar 28, 2012, at 2:39 PM, Glen Bojsza wrote: > > > > > The documentation seems slightly confusing (to me). > > > > > > On Linux I want to open a process for update, then write the command to > > be > > > executed and then read from the process and fill the output to a field. > > > > > > The command takes anywhere from 1 minute to 8 minutes to execute and > > while > > > it is running it outputs the various stages and results it currently > has > > > completed. > > > > > > In the terminal window if I just do the command line it produces > anywhere > > > between 20 to 100 lines of output where the final line has a unique > > output > > > acknowledging that it has completed. > > > > > > How should I be writing my read from process? > > > > > > I assume that this should be done inside a repeat forever loop where > you > > > can trap the mouseclick to exit or check for the unique output line > from > > > the read process to exit. > > > > > > I can't seem to any output from the read statement? > > > > > > Finally, is there a way to make this non blocking (ie let it run and > > update > > > the field while the user moves on to something else)? > > > > > > thanks, > > > > > > Glen > > > _______________________________________________ > > > use-livecode mailing list > > > use-livecode@lists.runrev.com > > > Please visit this url to subscribe, unsubscribe and manage your > > subscription preferences: > > > http://lists.runrev.com/mailman/listinfo/use-livecode > > > > > > _______________________________________________ > > use-livecode mailing list > > use-livecode@lists.runrev.com > > Please visit this url to subscribe, unsubscribe and manage your > > subscription preferences: > > http://lists.runrev.com/mailman/listinfo/use-livecode > > > _______________________________________________ > use-livecode mailing list > use-livecode@lists.runrev.com > Please visit this url to subscribe, unsubscribe and manage your > subscription preferences: > http://lists.runrev.com/mailman/listinfo/use-livecode > _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
