Title: JScript development and MDG Technoligies
Post by: SvenK on January 09, 2013, 09:36:30 pm

Hello,

as there is no feasible way to automatically import a couple of JScripts into EA, I started to investigate in MDG Technologies to do so.
However, I faced some problems:

I maintain a couple of scripts and stored them in different groups. However, the group information is lost when exporting as MDG. Do I have to maintain all scripts in a flat tree? This becomes very confusing.

It is not possible to edit scripts imported from MDG, which is on one hand obvious. However, how do I develop the scripts? Do I need a "master development project file" where the scripts are stored instead of imported as MDG and only develop functionality within this project?

Can I use variables in the !INC command to switch between script groups?
E.g.

Code: [Select]

var group="MyLocalGroup"
!INC <group>.myscript


Code: [Select]

var group="MyMdgGroup"
!INC <group>.myscript

Do you have a better workflow to develop JScripts and easily distribute/update them?

It is probably easiest to have a single model where you develop scripts. Yes, they will all be grouped into a group with the technology name.

To avoid needing to change your scripts to reference a group it's probably easiest to put them in a group by that name in the model you are developing them in.

Thanks for the hint.

In what table are the scripts stored? I was thinking of writing a script to import other scripts directly into the database.
It's is quite uncomfortable to be not able to versioning our scripts and to make diffs on changes.

It was easier to find than expected:
t_script

Title: Re: JScript development and MDG Technoligies

In the table t_script, the following fields are available:
ScriptCategory: Referece to an GUID; only different for Group or script
ScriptName: Unique GUID
ScriptAuthor: GUID of the Author
Notes: Short description of script type in XML
Script: The actual script content

However, in what table can the ScriptCategory be found.
And how to get a GUID when inserting an new script to the t_script table?

Any help would be appreciated.

From my book Inside EA concerning ScriptCategory:

Quote

A value to distinguish between group and script. It looks like a GUID but it has no “{}”
3955A83E-9E54-4810-8053-FACC68CD4782 = group
605A62F7-BCD0-4845-A8D0-7DC45B4D2E3F = script

q.

Thanks, so it is only a constant (same values in my project file).
With this I figured out that ScriptAuthor references to the Group where a script is stored (weird name).

So the last think I have to figure out is how to get a new GUID to use it as ScriptName if I add a new script.

Hi Sven,

I know this was answered some time ago, somewhere on this forum, bu i can't find it.

Anyways, you can use the GUID generated by the script below,

regards,

Paulus

Code: [Select]

Dim typeLib
typeLib = CreateObject("Scriptlet.TypeLib")

' GUIDs returned from typeLib have 2 unprintable characters at the end. Strip them off.
GenerateGUID = Left(typeLib.Guid, 38)

Thanks!

For the sake of completeness, this is the corresponding JScript code.

Code: [Select]

function getNewGuid()
{
      var typeLib = new ActiveXObject("Scriptlet.TypeLib")
      return typeLib.Guid.slice(0,38) // Last two character are unreadable
}

Here are some interesting details on why using TypeLib:
