Re: [Jbeta] data transfer fixes
Eric, I have just attempted your transfer process with the jod.ijs script. This is a 3000 line script so it's a good stress test. Good News: I was able to build the attachment and sent it to myself and save it as a temporary file. Bad News: The mangling required to stuff the script into html is not undone. The unmangle process you outline will probably work on most scripts but if text in the original matches HTML fragments it will break. Perhaps going to a safe encoding would do the trick. jdb On Tue, Jun 19, 2012 at 1:47 PM, Eric Iverson eric.b.iver...@gmail.com wrote: Thanks for the clear report. Progress, but not quite there yet.

Re: [Jbeta] data transfer fixes
A good test would be to use HTML source in place of J scripts. If the unmangle recovers the original it's probably good enough. I've long used wrapped txt=: LF, fread '~temp/t.ijs' enc=: 5!:5 'txt' It expands the scripts but completely eliminates delimiters that may clash with HTML On Tue, Jun 19, 2012 at 2:15 PM, Eric Iverson eric.b.iver...@gmail.com wrote: I thought the minimal mangling done was sufficient (assuming it is properly undone at the receiver).

The upload is easy, but what is required is a site that runs a server that allows http post requests that manage upload of files. A JHS server could serve this purpose.

[Jbeta] After reading about editing j iPhone sandbox files I gave it a try on a flight to Phoenix.
After reading about editing j iPhone sandbox files I gave it a try on a flight to Phoenix. The day before I loaded the main JOD files in the sandbox with the aim of getting JOD to run on the iPhone. My first attempt did not work. My JOD code thought it was on a Linux system. To make it work I opened up the main script (about 3000) lines using je. The iPhone did not choke on these large files. I made a few changes and successfully managed to load JOD, create dictionaries (jfiles based) and load some large dictionary dump scripts. Not all of JOD runs, I need regular expressions, and I have to change where I save some config stuff but all in all this little iPhone version of j is the real deal.

[Jbeta] Green input when debug engaged on jPhone
I've noticed that when you turn on the debugger (13!:x) and hit a stop the input field goes green. Since the normal color is restored when you turn off the debugger I presume this is by design. Also, for those interested in what's installed in the j iPhone directories. iTunes does not see files outside the root. Eric noted this already. However, you can copy entire directories off the iphone. Last night I copied the entire iPhone J directory off the machine to rummage around and see what's there.

Re: [Jbeta] Invoking the JGTK editor from the terminal.
One more comment about this: Eric, I have gotten used to your approach of displaying a link in JHS for opening J code to edit. It was a simple matter to tweak JOD to do: ed ;:'addloadscript mls' c:/documents and settings/jdbaker/j701-user/temp/addloadscript.ijshttp://127.0.0.1:65001/jijs?mid=openpath=c:/documents%20and%20settings/jdbaker/j701-user/temp/addloadscript.ijs One click brings up the script (in this case containing two words) in the JHS editor. The fact that the link persists in the log is VERY handy. I have been using both the JGTK and JHS environments for testing but I am spending more and more time in JHS. I've had to fall back on 13!:x debugging but for old J farts like myself that's not a big deal. The amount of memory consumed by jsconsole.exe is typically a tiny fraction of what Chome/IE/Safari consume and it is typically less than j.exe 6.02 as well.

[Jbeta] Remarks of lastest GTK Beta
I have been following all the messages about people having problems with GTK. Here's my latest set of observations for the current beta. 1) I never incrementally install new *.exe - so I wiped out my j701 directory - downloaded the latest gtkwin32.zip and reinstalled from scratch. 2) I don't use the install all option of jpkg - I prefer to install selected packages from JHS using chrome as my browser - no problems getting the packages I'm interested in. 3) At work - nestled behind the corporate firewall - requests to download via wget calls fail so I download the gtk binary by direct browser reference followed by a manual unzipping to the proper location in the j701 directories. 4) Then I start jconsole and run 'install' jpkg 'ide/gtk gui/gtk' to set any J specific configs required - look the main install verb for details. Once this is complete the j701gtk icon on the program menus starts up without problems. I have spend about 45 minutes playing with the front end and so far it's very smooth. No crashes and only one message in the jconsole window warning me that a GTK theme was missing. I have tried the gtk editor on my JOD dump scripts. JOD dump scripts are typically massive J scripts - sometimes containing hundreds of verbs and thousands of lines. The GTK editor takes a moment to load these monsters but once they are up all the GTK goodies, script coloring, side bar tags, token coloring works like a charm. There are some hidden slick features in the GTK editor that some of you may not be aware up. I changed the session font to APL385 Unicode and opened up some *.tex LaTeX documents that contained APL source code in UTF-8 format. To my utter delight the syntax coloring properly colored LaTeX commands and the APL text rendered perfectly side by side with J code. The only editor I have see do this before is the TexWorks editor. I think I'm going to like this GTK environment - good work guys. -- John D. Baker bakerj...@gmail.com -- For information about J forums see http://www.jsoftware.com/forums.htm
Re: [Jbeta] J701a - GTK Front End Install
I will add my observations on the current GTK beta install for windows machines. On my home machines I had no problem downloading a clean j701 beta and running install 'gtkide' in jconsole. On office machines - behind the usual corporate firewall the getgtkbin verb hangs. I looked at the definition of the verb and was oddly able to directly download the gtkwin32.zip in the browser. I expect the firewall recognized the browser request and allowed it but did not recognized the j request. Once you get the zip - unzipping to the proper directory results in a system that so far looks ok. On Mon, Jan 10, 2011 at 3:20 PM, Don Guinn dongu...@gmail.com wrote: I see them now. Thank you.

I had successfully loaded the win32 version under Vista with both jhs and jgtk working ok - but I was trying to solve my own problems with the user folder not being where I wanted it, and decided to reinstall j701. I didn't want to lose all the addons as it's time-consuming to download them, so I deleted the contents of most J folders (bin, system, etc), but not those under addons. After reinstalling J701, I encountered the same behaviour as reported by William Szuch, ie an invitation to install 'gtkide' which I did. This resulted in a lengthy sequence of download and expansion messages. I then complied with the request to load 'gtkide' which did not succeed. I tried another install 'gtkide' which I think yielded the message that it was already installed. After a bit of thought, I deleted only those folders under addons which appeared to have contents related to gtk. I also deleted gtk stuff elsewhere under j701, ie under install. This time, install 'gtkide' followed by load 'gtkide' was successful. I think I might have needed to reload one or two addons using pacman, but certainly not all. I dont recall any difficulty with readonly files or folders. This is roughly what happened. I'm afraid I didn't exactly record everything that occurred as I was just trying to deal with my own problems at the time. It looks as if a facility to uninstall all or part of J would be useful.

Re: [Jbeta] 64 bit COM interface in j7?
Thanks Eric, I was thinking the same thing. I will probably go with the sockets connection as it allows greater flexibility down the road.

Re: [Jbeta] new j701 beta for all platforms

However, since your report says the window just flashes and dies there is a good chance that will just happen here as well. If it flashes and dies we'll have to step through the jhs initialization to see where the problem is. The initialization is not very complicated. Bascially it creates a listening socket, binds it to port 65001, and then switches to jfe mode where input and output are done with J verbs. Until you get the server to start successfully, there is no point in fiddling with the browser. Is your system perhaps configured in some security way to kill apps trying to establish listening sockets? You could extract the socket stuff from init_jhs_ to see where the trouble is. It creates a socket, binds to port 65001 and localhost, and does a listen. My guess is the trouble is here, rather than in the switch to JFE mode. On Wed, Jun 9, 2010 at 8:09 AM, R.E.

Re: [Jbeta] Gtk IDE
This scheme works nicely. I haven't looked under the hood but how are the
regex's being applied? Does it occur in J or in the GTK editor.
Chris, I think I will get used to the (defs names) pretty quickly. It's a
nice relevant way to jump around in J source files. I have tried the editor
with large semi-compiled JOD scripts that contains hundreds of defined
names. Of course it slows down but is still useful. For scripts with less
than 30 names it's almost the bees knees.

Re: [Jbeta] Gtk IDE
I installed the windows version and kicked it around a bit. For an early beta this looks quite promising. It will be nice to standarize gui's across the three main J platforms, windows, linux mac.

If seems that only outer comments are colored NB. this comment is outside explicit definitions are get colored. someverb=: 3 : 0 x + y ) Inner comments do not get colored someverb=: 3 : 0 NB. this comment is inside explicit definitions - it doesn't get colored. x + y ) as a matter of style I prefer inner comments for explicit definitions because they can be quickly displayed in the console.

Re: [Jbeta] J7 IDE
The devil is always in the details. I am generally in favor of replacing native foreigns with cd calls but the potential removal of the 1!: and 2! families caught my eye. If this step is taken please provide clear scripts on the various platforms illustrating how these verbs can be replaced with equivalent cd calls. I am particularily concerned about losing the component file facility in jfiles that sets on top of the indexed read 1!: calls.

Re: [Jbeta] VB COM Interface
This may be BINPATH related I will do some checking. On Feb 3, 2008 7:28 AM, Eric Iverson [EMAIL PROTECTED] wrote: I haven't checked carefully, but I believe the J server bugs with BSTR lengths were fixed in the 601 release. At quick check shows no differences in that area between 601 and 602. Your example with SysAllocStringLen is correct that a null is always at the end of a BSTR memory allocation and although part of the memory allocated is not included in the BSTR length count. I think (but haven't checked) that the integer count preceeding the BSTR pointer is in fact a byte count and not a wchar count. That is, in your 'test' BSTR example the value in the preceeding length is 8, not 4. There were some changes in the J server and these are documented in Help|User Manual|COM, OLE, and OCX|J OLE Automation Server The important change is that the sentences necessary to load profile and get an ijx window are different than in 601.

I also encountered this before so I made a test app to try it again. In the attached zip file are: 1. StringTest.DLL - the DLL to be called by the J script. For the non VB savvy, its similar to an OCX. 2. stringtest.ijs - the J script that acts as a wrapper to StringTest.DLL 3. jtestvb.JPG - a screenshot of my VB IDE while debugging the test. You can see J session at the back of VB. 4. Various VB files - so you can recompile the thing yourself with VB6. ;) So to make a long story short, J did not add an extra space at the end of the string but instead added a 0 (or in C notation a \0 ). I think this has something to do with how J handles strings ... as zero terminated character arrays. :) Can we consider this as a bug? I actually don't know ... you see I've been lucky since I have never consciously called a 3rd party DLL/OCX without making a VB or C/C++ wrapper between the 3rd party object and J. What I'm saying is that if it becomes a problem, I'll just strip it off myself.

[Jbeta] VB COM Interface
I have been running a VB/COM application for a number of years. If's a VB6 application that mostly passes BSTR's to a J application. None of the betas in the current 602 cycle work with this application. The last J version that works is 6.01. Registering j602 and using this app results in a series of errors. The BSTR interface has changed in some way. Has only else experienced difficulties with similar applicaions. jdb -- For information about J forums see http://www.jsoftware.com/forums.htm

Anssi At 19:12 29.5.2006, you wrote: In a change like x for x. there is a cost. The question is who pays. Jsoftware policy is to favor new users over old. A new user should find things as clean as possible. A new user, with a newly installed system, getting their first taste of J, should not be distracted with the x. and y. historical baggage. Or any other barnacles from the past. As much as possible the cost of the change should be borne by old users. I hope the reasoning behind this is obvious, if not agreeable. J is used by a small community. A community that is too small. Jsoftware is dedicated to growing this base and we feel this is best done by presenting well to new users. An old user has been involved in discussion of the change and can work out their own manner of coping. A new user would be confused and could focus on this dead tree rather than the forest. With luck the user base will grow until the emphasis has to shift to favoring new to old users. We look forward to that day. -- For information about J forums see http://www.jsoftware.com/forums.htm -- For information about J forums see http://www.jsoftware.com/forums.htm
