$zhex
hex to dec

write $zhex("99")
​153

and back, dec to hex

write $zhex(153)
​99

be careful, hexadecimal should be a string and decimal should be a number

There are no particular recommended SourceControl systems. Everything depends on your choice.

Some time ago, with versions cache less then 2016.2 and before Atelier was appeared, we could use nothing except Studio. And in this case to work with particular SourceControl we should write own addon for Studio as a wrapper for this SourceControl. You can find one as a good example here on github, which works with GIT

Now, when we have Atelier, we could forget about this part, and use lots of available plugins for different SourceControl systems.

BTW, I prefer git, but most of time used SVN at work, and git for my own projects.

It's a right way, but don't you think, that you forgot to save your changes ? something like this

w rtn.%Save()

or you can just use $system.OBJ.Load("les.mac") or $system.OBJ.Load("some.class.cls") in versions 2016.2+
if you have less version but not less then 2014.1, you can load class with %Compiler.UDL.TextServices  as I've already offered to use it for export on stackoverflow

As I'm not sure what you mean by 'dead' locks, I'll just show simple code for looking all locks in current namespace

    set lockName=""
    for {
        set lockName=$order(^$LOCK(lockName))
        quit:lockName=""
        set mode=^$LOCK(lockName,"MODE")
        set owner=^$LOCK(lockName,"OWNER")
        write !,mode,?4,owner,?12,lockName
    }

What do you mean by dead locks ?

Studio reformats some class parts, such as Methods defenitions when you save it.

But as I know feature Atelier, stores class definition as is, so you do not need more such option, just format class as you need, and it should keep so.

Timur, you can look at my example at github which I wanted to use in to article about using docker but have not managed yet. In this example I have Dockerfile for ECP-client, which can be build for particular ECP-server. And with %Installer manifest possible to make backward data channel too, while we have already known about where our server placed, we can connect to him via %Net.RemoteConnect or something else and make new backward connection, the problem is in this case how to remove old ones. I played only on one machine. But in anyway, Ansible still could be useful, but in case to prepare servers to work in docker cluster,  which should be prepared before we could use docker-compose and so on. And My example also contains web-server (apache), to have an access to this new instance. What I wanted to do then is to use some load balancer, HAProxy or traefik (as recommended Luca), to get one point access to my application, and dynamically expandable, without any manual operations, except scaling.

Yes, such language extension is very useful, but there is one more feature less known, and unfortunately completely undocumented. Its structured system variables, some of them could me familiar it is: ^$JOB,  ^$LOCK, ^$GLOBAL and ^$ROUTINE. More information in documentation here. But not all knows that it is possible to make your own such global. You should create routine with name SSVN"global_name" in %SYS namespace, for example SSVNZA for ^$ZA global

and for example with this code below, you SET, GET, KILL any values in this global, and this global will contain individual data for every session, and it is possible to use $order or even $query for  such global

ROUTINE SSVNZA
#define global $na(^CacheTemp.ZA($select($isobject($get(%session)):%session.SessionId,1:$job)))

fullName(glob) {
    set global=$$$global
    for i=4:1:glob set global=$na(@global@(glob(i)))
    quit global
}
set(glob, value) public {
    set global=$$fullName(.glob)
    set @global=value
}
get(glob) public {
    set global=$$fullName(.glob)
    quit @global
}
kill(glob, zkill=0) public {
    set global=$$fullName(.glob)
    if zkill {
        zkill @global
    } else {
        kill @global
    }
}
order(glob, dir) public {
    set global=$$fullName(.glob)
    quit $order(@global, dir) 
}
query(glob, dir) public {
    set global=$$fullName(.glob)
    set result=$query(@global, dir)
    quit:result="" ""
    set newGlobal=$name(^$ZA)
    for i=$ql($$$global)+1:1:$ql(result) {
        set newGlobal=$name(@newGlobal@($qs(result,i)))
    }
    quit newGlobal 
}

But as I said before, as it is completely undocumented feature a bit difficult to get complete compatibility with ordinary globals. But it still could be useful, in other cases, like it used by InterSystems.

My result is 157 :)

Actually, XData content it is a just XML, in it is stored exactly as you wrote it in IDE. But it is possible to compile any XData to any other format as you need, at this portal you can find two articles about how to do it, first and second. In your case it could be much easier, like some method which in compile mode gets all XData content and place it to &html<>, which then compile again as usual, and what you need after it is just call this generated method, to show this html. 

Steve,

I would recommend to distant webservers from ECP Application servers. In your case I would install webserver exactly on the server where ECP Application Server have already installed, so in this case your connect via superport will be secured, and in this case only web port should be opened in the firewall. Outside of this servers after firewall you need to use some load balancer, in this case I would recommend to use HAProxy. Connection between extarnal HAProxy and  internal webservers could be secured with ssl, but I'm not sure that is really needed.

And in this case it is possible to store all static content such as JS, CSS and images on server where load balancer placed, to avoid redundant request to the data servers. It is not a big problem for the production systems.

So finally in simple view it my looks like below.

Many times I need to get some link from documentation, to show particular part to someone. And some time it is quite difficult to get such link, and the worst place in Class References, where I can't get good link for a particular part of class.

So, what I need is, an active icon with link, which then I can use, and for Class reference too.

As an example github.

You could just pass this arguments in Execute method, something like this

    new $namespace
    set $namespace="%sys"

    Set tRS = ##class(%ResultSet).%New("%SYS.Journal.File:Search")
    Set tSC = tRS.Execute("test", "/opt/cache/mgr/journal/20160507.001")
    if $$$ISERR(tSC) {
        do $system.OBJ.DisplayError(tSC)
    }
    
    do tRS.%Display()

this code will return all offset's which contains text - 'test'

You must remember that this query should be executed only in %SYS namespace.

Usually we could use some another modern ways, which allow us to call queries.  

    set statement=##class(%SQL.Statement).%New()
    set tSC=statement.%PrepareClassQuery("%SYS.Journal.File","Search")
    if $$$ISERR(tSC) {
        do $system.OBJ.DisplayError(tSC)
    }
    Set tRS = statement.%Execute("test", "/opt/cache/mgr/journal/20160507.001")​

or even much shorter

    set tRS=##class(%SYS.Journal.File).SearchFunc("test", "/opt/cache/mgr/journal/20160507.001")
    
    do tRS.%Display()

But unfortunately such code snippets does not work in case when Query does not contain any parameters in his original declaration.

After this error you should look at cconsole.log, where you can find error code, why loading was failed.
Mostly there are two errors with loading dll in cache,  using 32bit dll instead of 64bit. And if this library has unsatisfied dependencies, in this case I'm using this tool to find such dependencies.
