Under My Computer"/Tools/Folder Options/File Types" I added a new type
called "ijs". In it I defined several options with one called "Run" as a
default. It is defined as
"c:\Program Files\j\J601\j.exe" -jprofile d:\juser\config\runprof.ijs "%1"
runprof.ijs is a script which sets up the full development environment
except no ijx nor the ijs windows is displayed. It also sets up error
handling so if there is an error the ijx window pops up to show the
error instead of just J going away. It also allows the ijs script to be
anywhere instead of just under ~user.
I haven't looked at it in a while; however, the script below should work
for you. But if there is a problem let me know. Anyway, it should give
you enough clues to write your own. This is the runprof.ijs script:
NB. Profile for runtime. ______________________
0 : 0
This alternate profile will run a script file name in the forth item in
ARGV_z_
if it exists. The environment that the script runs in is the same as if
it were
run in the J development mode. Therefore, any script developed and
tested in the
J development mode can be run as a standalone application simply by
starting J
as follows:
Jsystempath\j.exe -jprofile userpath\config\runprof.ijs scripttorun
[more args]
The folders for J, current directory and scripttorun are independent of
each other.
If profile.ijs is modified to allow the user data to be outside the J
folders then
it is independent also. If the unmodified version of profile.ijs is run
then
userpath would be the same as Jsystempath.
When scripttorun gets control the -jprofile and runprof.ijs items are
removed.
So, when scripttorun gets control, ARGV_z_ will look like
+-----+-----------+--------+---------+
|j.exe|scripttorun|optional|arguments|
+-----+-----------+--------+---------+
By defining the file type ijs to envoke J as described above means that
any ijs
file can be run as a standalone application by simply double clicking
the file
name in a directory list or from a shortcut to the file. It is not
necessary to
use the J Project Manager to make a standalone application.
The current directory is saved over the running of profile.ijs so if
profile.ijs
were modified to use the current directory it will still work properly.
The *.ijx window is suppressed by setting IFJIJX_j_ to one before
passing control
to profile.ijs. It looks like scripttorun should be run as part of
profile.ijs
as ARGV_z_ is set up to run it; however, for some reason when IFJIJX_j_
is set to
one it doesn`t run it. So there is a separate load to run it.
Most of this script is enclosed in a local verb to make sure that the
local names
are really local and disappear before scripttorun gets control.
To do:
Fix the load of scripttorun to watch for errors and open an ijx window
if an error
occurs.
Might want to add another parameter, -edit, which means to bring up the
script in
an .ijs window instead of running it.

In addition to "Run" I added a few other commands - "Edit" to bring up a
script for testing without having to start J first.

Does anyone know if it's possible (under MS Win) to associate an ijs
file with J such that when you double-click on the ijs, J starts up
opens the file in its own window (ie equivalent to starting J and then
doing File Open on the file you've selected)? Is this something that
windows users think might be useful?
