`ScriptManager` (ScriptManager) is a utility useful to manage scripts in a workspace.
Line 7: Line 7:
Obviously it makes sense to make `ScriptManager` available as a User Command. This User Command prints the fully qualified names of functions and operators together with time stamps and the user names to the session, sorted by time stamp (oldest first).
Line 9: Line 9:
This page offers a small class script `ScriptManager_UC.dyalog` which is designed to do exactly that. Note that fns/opr in scripted namespaces are '''execluded'''. In the context of a command latest they don't offer real value since they all get the same time stamp when the script gets fixed. This is more often misleading than useful.
Line 11: Line 11:
== Assumptions ==
In order to make `ScriptManager` available as a user command the script `ScriptManager_UC.dyalog` ("UC" for User Command) attached to this page must go somewhere where Dyalog is able to find it. There are to options:		 The following is a sample session taken in the workspace "CPro" (Causeway) a Dyalog installation is coming with at the time of writing (2012-03).
Line 14: Line 13:
 * Move it into `Salt\Spice` inside the Dyalog installation folder. That's where the Dyalog User Commands are located.
 * Create a particular folder for your own User Commands.		 An empty vector means ALL fns/opr:
{{{
      ]q←Latest ⍬
      ⍴q
1832 3
}}}
Line 17: Line 20:
Although the first option is certainly easier, it's actually the second one which is recommended. There are a couple of reasons: A positive integer n is treated as "report n fns/opr changed most recently", therefore you get 6 or less objects printed to the session:

 * Messing Dyalog scripts with your scripts is not a good idea.
 * When a new version of Dyalog arrives you are in trouble.
 * Having a separate folder for your own User Commands allows you to overwrite a Dyalog User Command with an improved version you are not going to loose in case of an update or a new version.		 A negative integer n is treated as "report all fns/opr changed during the nth recent days":

Line 23: Line 44:
To make your own User Command folder work you have to do a couple of things: Note that you cannot specify the negative value as `-4` rather than `¯4` because Dyalog considers it to be a switch then and refuses to accept that.

 1. Add the folder to the SALT search path.
 1. Create another folder which is going to host the "real thing". A recommended name is "!UserCommandCode".
 1. Copy the script `ScriptManager_UC.dyalog` from the ScriptManager page into that folder.
 1. Create a registry entry pointing to that new folder with the name `HKEY_CURRENT_USER\Software\Dyalog\Dyalog APL/W 12.1 Unicode\SALT\CodeFolder`		 By default `Latest` investigates `#`. With the optional switch `-s` one can change that. The following statement returns 6 fns/opr from the namespace `#.Class.IC`:

Line 32: Line 59:
In order to achieve that the script `ScriptManager_UC.dyalog` reads the `HKEY_CURRENT_USER\Software\Dyalog\Dyalog APL/W 12.1 Unicode\SALT\CodeFolder` from the Windows registry. It then tries to load the "real" `ScriptManager` script from that folder. Occasionally it might be useful to include fns/opr from scripted namespaces as well. This can be achieved with the `-a` switch (for "all").
Line 34: Line 61:
Note that not only our examples given on this page but also the code in `ScriptManager_UC.dyalog` all refer to version 12.1 Unicode of Dyalog. If your are using a different version of Dyalog of course you must change the script, otherwise it's not going to work. Let's create a scripted namespace in order to get something to bite into:

User Command "Latest"

Overview

This User Command prints the fully qualified names of functions and operators together with time stamps and the user names to the session, sorted by time stamp (oldest first).

Note that fns/opr in scripted namespaces are execluded. In the context of a command latest they don't offer real value since they all get the same time stamp when the script gets fixed. This is more often misleading than useful.

The following is a sample session taken in the workspace "CPro" (Causeway) a Dyalog installation is coming with at the time of writing (2012-03).

An empty vector means ALL fns/opr: 

      ]q←Latest ⍬                 
      ⍴q
1832 3

A positive integer n is treated as "report n fns/opr changed most recently", therefore you get 6 or less objects printed to the session: 

      ]Latest2 6

 #.Class.Qualify     2008.02.22 18:52:15  Adrian

 #.CPro.Fns.Exec0    2008.02.22 19:43:40  Adrian

A negative integer n is treated as "report all fns/opr changed during the nth recent days": 

      ]Latest2 ¯2
 #.CPro.Class.EventNumber  2008.01.24 14:46:02  Adrian 
 #.Class.MakeBitmap        2008.02.22 18:37:41  Adrian

 #.CPro.Fns.Exec0          2008.02.22 19:43:40  Adrian

Note that you cannot specify the negative value as -4 rather than ¯4 because Dyalog considers it to be a switch then and refuses to accept that.

By default Latest investigates #. With the optional switch -s one can change that. The following statement returns 6 fns/opr from the namespace #.Class.IC: 

      ]Latest2 ¯5 -s=#.Class.IC
 #.Class.IC.Caption      1997.07.31 18:13:06  Adrian 
 #.Class.IC.Design       1997.07.31 23:38:26  Adrian

 #.Class.IC.Refresh      2008.02.22 19:42:32  Adrian

Occasionally it might be useful to include fns/opr from scripted namespaces as well. This can be achieved with the -a switch (for "all").
