`ScriptManager` (ScriptManager) is a utility useful to manage scripts in a workspace.
Line 7: Line 8:
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 10:
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.

Refer to UserCommands/WhereShouldTheyGo for advice how to organize your User Commands. 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).

== Problem with SALT == An empty vector means ALL fns/opr:

Line 15: Line 21:
When you get a "Target namespace not found" error reported by SALT but crashing ScriptManager than you are using an outdated version of SALT. Ask Dyalog for a better version of SALT where this bug got fixed. 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:
{{{

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

}}}

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

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

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.Initialise  2008.02.22 18:40:42  Adrian 
 #.Class.Qualify     2008.02.22 18:52:15  Adrian 
 #.Class.PM.Refresh  2008.02.22 19:01:15  Adrian 
 #.Class.IL.Refresh  2008.02.22 19:27:25  Adrian 
 #.Class.IC.Refresh  2008.02.22 19:42:32  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 
 #.Class.Initialise        2008.02.22 18:40:42  Adrian 
 #.Class.Qualify           2008.02.22 18:52:15  Adrian 
 #.Class.PM.Refresh        2008.02.22 19:01:15  Adrian 
 #.Class.IL.Refresh        2008.02.22 19:27:25  Adrian 
 #.Class.IC.Refresh        2008.02.22 19:42:32  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.Create       1997.08.01 11:50:52  Adrian 
 #.Class.IC.onConfigure  1997.08.01 11:54:51  Adrian 
 #.Class.IC.Read         1997.09.01 15:36:54  Adrian 
 #.Class.IC.Fns          2008.01.23 12:51:28  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").

Let's create a scripted namespace in order to get something to bite into: 

      ⎕fix ':Namespace Foo' '∇r←Hello' 'r←''World''' '∇' ':EndNamespace'
      ]Latest2 3
 #.Class.IL.Refresh  2008.02.22 19:27:25  Adrian 
 #.Class.IC.Refresh  2008.02.22 19:42:32  Adrian 
 #.CPro.Fns.Exec0    2008.02.22 19:43:40  Adrian 
      ]Latest2 3 -a
 #.Class.IC.Refresh  2008.02.22 19:42:32  Adrian 
 #.CPro.Fns.Exec0    2008.02.22 19:43:40  Adrian 
 #.Foo.Hello         2012.03.05 16:20:35  Kai
