go to post Dmitry Maslennikov · Apr 30, 2019 1. What you did, to get it. Please add all your steps, so we can find what you did wrong.2. IRIS container changed nothing what comes from base Ubuntu image. If you can install mc there it should be possible on IRIS as well. But I don't see any reasons, why mc should be available inside the container. And why you need it there?
go to post Dmitry Maslennikov · Apr 25, 2019 I think you are talking about subscripts and about the full length of global reference. You can't do anything with it and just accept it as a fact.
go to post Dmitry Maslennikov · Apr 22, 2019 It's not so much important to have key before install, much more important to have it when server is running.But how you sure that your key is suitable for this platform. You can check it on running container, where you can enter inside, and go the csession. You can find some intersting methods for $SYSTEM.License in the documentation which can help you to check license file inside the container.
go to post Dmitry Maslennikov · Apr 22, 2019 Most of the reasons for getting such error is just missed license file or exceeded license limit.Just check it, you can mount it during docker run or copy it inside the image during docker build.I see that you use quite an old version, I would recommend considering usage latest version based on IRIS. Due to many limitations of using such an old version in Docker.
go to post Dmitry Maslennikov · Apr 15, 2019 So, you can convert $List to some kind of List in C?$LIST is a very simple format, but you can't get any particular item just by position. You should go through the list from the first item.In a simple explanation, it is just concatenation of individual $LIST. So, you can't say how many items you have until you go through this list and count them.
go to post Dmitry Maslennikov · Apr 15, 2019 I have not played with C, yet. But I found CachePopList and CachePushList. have you tried to play with it? Looks like it may help you to order over $List.
go to post Dmitry Maslennikov · Apr 13, 2019 Sure, all project specific settings, should be stored in .vscode folder In the root of project. So, you can control this folder with source control system. Look at the VSCode documentation. And at one of my ne projects as an example.
go to post Dmitry Maslennikov · Apr 12, 2019 It's really great news. And so cool that InterSystems started to participate more in developers conferences. I wish to participate all of them :)
go to post Dmitry Maslennikov · Apr 10, 2019 Base64 does not work with unicode with two or more bites. You should convert it first write $system.Encryption.Base64Encode($zcvt("тест","O","UTF8")) 0YLQtdGB0YI=
go to post Dmitry Maslennikov · Apr 10, 2019 Some time ago I did an example of Angular Application with IRIS on a backend.Source for this project available on gitlab.How to develop Angular application, you should look at angular documentation, and all about frontend development. There are some tools, which helps to develop and build your frontend side. Such as webpack, which do most of work related with build your sources to production ready environment.In my simple project, you need only docker, and any editor, preferable VSCode.By command, you will get a running server in development mode. So, you can edit Angular code, and IRIS code, and see an immediate result. docker-compose up -d And this project also deployable with Kubernetes. So, after any push of changes to gitlab, it will build, and test it. node_modules, never goes to source control. It's enough to have package.json and package-lock.json there. node_modules may contain platform specific libraries. Hope I will manage to write a complete article about this project, with all the details.
go to post Dmitry Maslennikov · Apr 10, 2019 Sorry, usually I use it to add custom methods to properties. Did not not, that it doesn't work for such methods as Set/Get. But you can add any other method.
go to post Dmitry Maslennikov · Apr 9, 2019 Why do not use PropertyClass, so, you can generate own getter and setter for any property in a class?
go to post Dmitry Maslennikov · Apr 4, 2019 There is also ClassMethod GetGlobalSize in the class %Library.GlobalEdit , where you can select a fast way to count or not, and you will get a different result. ClassMethod GetGlobalSize(Directory As %String, GlobalName As %String, ByRef Allocated As %Integer, ByRef Used As %Integer, fast As %Boolean = 0) as %StatusGet size of this global'Allocated' - total size, in MB, of blocks allocated for the global.'Used' - total used data, in MB, for the global.'fast' - TRUE : faster return, it won't return the value of 'Used'.FALSE - slower return,, it returns values for both 'Allocated' and 'Used'.So, when fast, it just counts blocks and don't care how those blocks fill by data and multiply the number of blocks on Size of the block.Used, counts only when you pass fast=0, and it calculates exact size, and to be more accurate reads all blocks, so it could be slower.

go to post Dmitry Maslennikov · Apr 3, 2019 Visual Studio and Visual Studio Code are two very different products but just with similar names.To configure Visual Studio Code, you can use this settings { "objectscript.conn": { "active": true, "host": "localhost", "port": 57772, "ns": "SAMPLES", "username": "admin", "password": "SYS" } } Where, active, should be true, if you going to be connectedport should point to Web server port, and not super portusername/password, the user should have enough permissions with role %Development
go to post Dmitry Maslennikov · Apr 2, 2019 Very interesting, I did not now that LaTex maybe used in such a way. How it is used Syntax Highlighting, maybe I can help? How Pygments related? Some time ago I started to do Syntax highlightings to Pygments but did not finished it, yet. But I have textmate grammar, which can be used in many places.
go to post Dmitry Maslennikov · Mar 27, 2019 I'm not an InterSystems guy and can say only from my point of view, how it works.Every global name has internal representation in some kind of binary format, I don't know how it can be converted to and back. But this string used to find a correct block. Like when you looking for ^C(9996,46, yellow), it first should read Map (Block 3), to find where Global ^C started (Block 44), then using this internal format for global, it can find the closest node in the first pointer block if it points to another pointer block, the same search repeats until it reached any Data block, which may also contain data for multiple nodes. Not sure If I can better explain it, but most important is that B* tree helps to very quickly find the final block, and their neighbours.
go to post Dmitry Maslennikov · Mar 19, 2019 There is a workaround with a storage driver. Here is an example of ccontrol-wrapper which can help with it. And example of Dockerfile how it can be used.
go to post Dmitry Maslennikov · Mar 19, 2019 I would argue about using VM instead of Docker. My choice is Docker for sure, for many reasons. It is not so difficult to make it worked in Docker, and you will get a lot from it. And if it is possible for you to move to IRIS, it would be a good way to go.I've been working for many different projects at the same time, and use Docker for all of them.
