go to post Nikita Savchenko · Jan 21, 2017 I hope so! :) Or we can even think about some kind of "screen debugger" for terminal like it was suggested.
go to post Nikita Savchenko · Jan 20, 2017 Good news! Today we figured out how to implement Ctrl+C interrupts in WebTerminal. Thanks to Mark for pointing on this.Now WebTerminal will prompt you to update to version 4.1.2, which includes Ctrl+C interrupts implementation. See the related docs: when there is any selection, Ctrl+C will work as a normal text copying. But when there is no text selected, Ctrl+C will work as an interrupt.Mark, I need a bit more time to implement non-freezing long output behavior, but it is in my list now and will be implemented soon. Thanks for your comments!
go to post Nikita Savchenko · Jan 20, 2017 Mark,Good point on the output issue. I was thinking to make non-freezing output during the development but postponed this idea in favor of synchronous output (which is freezing browser until all the content renders). I will take this into account in future versions of WebTerminal.CTRL-C for now works as a default combination for copying text. Unfortunately, after reading documentation a lot, I am still having no idea how to implement interrupt in WebTerminal. Technically speaking, I need to send the interrupt signal to a jobbed process somehow, but continue to execute it from, for example, some label in the COS code. Any help here is appreciated!To track the interrupt enhancement, I have created this issue.
go to post Nikita Savchenko · Jan 19, 2017 Hello Mark, thank you!I did a little fast research and found that it is possible to make the behavior of printing long output similar to the standard Caché terminal (just to make terminal scroll and scroll through the text until the output stops). But how do you think, does it makes sense to replace this "freezing" behavior with always-scrolling output? In both cases, the output is not readable (normally readable). Maybe it makes more sense to display a floating message like "Output in progress..." when WebTerminal freezes for more than 1 second?Would be glad to hear your opinion, thanks!
go to post Nikita Savchenko · Jan 3, 2017 Thanks for hint, Edward, but how can I start using it? open 3564 use 3564 write ##class(%Library.Device).GetType() close 3564 command throws <NOTOPEN> exception.
go to post Nikita Savchenko · Jan 3, 2017 Hello Sebastian!I am glad to hear you like WebTerminal. I do as much as possible to make it even better.For now, WebTerminal may still have some escape sequences not implemented, and there is one issue that may also cause old "dinosaur" application to work in a little bit different way. If you find the reason causing the terminal application not to work as expected, please, feel free to describe this in the GitHub's issues section.
go to post Nikita Savchenko · Jan 3, 2017 Kevin,Please see my answer below and tell me if it helps.Try using the browser's incognito mode or reinstalling WebTerminal if you need to log in from scratch.
go to post Nikita Savchenko · Jan 3, 2017 Hello Kevin!It's all about setting up the /terminal web application. Go to the Management Portal -> System Administration -> Security -> Applications -> Web Applications, then choose /terminal web application.There you can specify the required resource for this web application:For example, you can specify %Development resource, which means that any users that do not have the access to this resource will not be able to log in to WebTerminal.As _SYSTEM user has this access, you can create a custom resource, for example, WebTerminal, and create a role WebTerminal which provides the access to this resource, and then set up this role to the web application and assign this role only to those users you want to have access to WebTerminal.Please, feel free to ask if you need more details about setting up roles and resources.Thanks for the good question!And a question to community: I think creating WebTerminal role/resource programmatically during the WebTerminal installation makes sense, does it? As well as adding some documentation on setup/use/roles/etc.
go to post Nikita Savchenko · Jan 3, 2017 OK, WebTerminal v4 doesn't have any problems with USE command anymore. The last thing left to deal with is probably the current device detection.
go to post Nikita Savchenko · Dec 10, 2016 Stefan,I think it makes sense to edit this article a bit and replace all "dying" system methods with their working analogues, e.g. .$toJSON() -> .%ToJSON(), etc. Do we ready to do so in terms of transition back to no system methods?This article has a good search engine ranking and I usually use information from here.Thanks!
go to post Nikita Savchenko · Nov 7, 2016 Thanks to Bernd, I finally found that this is not a Caché sessions unexpected behavior, the reason is in the browser's basic authentication cache.To clear the browser's cache, here is one "dirty" solution for this: stackoverflow (and probably the only solution). The JavaScript function sends the wrong login/password authentication request to the server, and it results as 401 Unauthorized error. And this forces browser to clear its cache.
go to post Nikita Savchenko · Nov 7, 2016 I did log in exactly as I described: When I come to the /playground/index page at first, Caché meets me with an authentication window, asking to enter my username and a password. The output of the log is the next: You're logged in as _SYSTEM SessionId = xH9mWezT2o, NewSession = 1 Thank you!
go to post Nikita Savchenko · Nov 7, 2016 Hello Bernd,Yes, I did: ClassMethod Logout() As %Status{write "Bye, " _ $Username _ "!"do %session.%SaveData()set %session.EndSession = 1do %session.Logout(1)quit $$$OK} I tried %SaveData as documentation says as well, and this doesn't result as expected neither.
go to post Nikita Savchenko · Nov 2, 2016 Wow, thanks, I thought that this routine will just be executed before the terminal session start and then the normal terminal session will happen.Do you know is it possible to achieve this behavior? Thank you!
go to post Nikita Savchenko · Oct 3, 2016 Hello John!This tool is available for Caché 2013.1+ versions (REST support).
go to post Nikita Savchenko · Jun 30, 2016 Thanks, Fabio!Good to know about SPOOL device. Thank you! However, this method touches ^SPOOL global. Being set before the call, ^SPOOL global changes it's value, which is not secure for my needs.P.S. Recently, Stuart gave me a complete answer. Thanks for your help!
go to post Nikita Savchenko · Jun 30, 2016 Thank you, Stuart!I think this is a complete solution. I wrapped it to a class method and it works just as expected: ClassMethod VarList() As %String{ IF $DATA(%) ; This places the existence of variable % into $TEST. NEW % SET %=$SELECT($TEST:$LISTBUILD("%"),1:"") SET:$DATA(%0) %=%_$LISTBUILD("%0") NEW %0 SET %0="%0" FOR { SET %0=$ORDER(@%0) QUIT:%0="" SET %=%_$LISTBUILD(%0) } QUIT %}Results withUSER > write%=11a=<OBJECT REFERENCE>[1@DevProject.Robot]i=5USER > zw ##class(DevProject.Robot).VarList()$lb("%","a","i")USER > kill %USER > zw ##class(DevProject.Robot).VarList()$lb("a","i")
go to post Nikita Savchenko · Jun 15, 2016 Nice! Will wonder if you have some sort of more-liner, which also saves and restores objects (orefs). But I believe it is not too useful.
