Re: [Jgeneral] Change font size in JHS?
There was a typo in the line. The comma between startup_jhs and ijs should have been a period. Following is the corrected line: 'PC_FONTSIZE_jhs_=:''22px''' fwrite jpath'~config/startup_jhs.ijs' This works for me. Note that you have to stop the JHS server and restart it to have the startup_jhs script loaded.

Then shutdown JHS and restart. This is not working. It seems that startup_jhs.ijs is not being run at startup; at least the font is not changing. However, if I explicitly open and run that script, then the font size immediately does change (so evidently I didn't mistype the command in the file). This is under OS X, in case that makes any difference. -- Murray Eisenberg mur...@math.umass.edu Mathematics Statistics Dept.

Re: [Jgeneral] How to advance chapters in labs
Rather than stay stuck at J602, some enterprising soul could provided some wrappers and instructions for the simple chapter management verbs in locale jlab.

Re: [Jgeneral] Change font size in JHS?
JHS fontsize when a page is created is determiined by variable PC_FONTSIZE_jhs_ In your JHS session try: PC_FONTSIZE_jhs_ 11px PC_FONTSIZE_jhs_=:'22px' reload the page to see the new size You could put this in a startup script or in the jhs config file.

Re: [Jgeneral] J on iOS: how recall sentences into entry field?
There are 2 ways: Touch the log area to get the cursor on the line you want to recall and then press the return button (not the keyboard return key). or Do a careful left swipe in the input area. This takes a bit of practice. Experiment wiht left and right swipe to move through the recent lines. A swipe is a touch or the screen and an almost immediate sideways movement on the screen.

Re: [Jgeneral] jdll.h missing from j701
I think everything should work in J7 except for cdf for the reasons Bill pointed out.

Re: [Jgeneral] jdll.h missing from j701
Raul, Bill is correct that cdf unload all dlls that cd has loaded. This wasn't too bad in the old J602 days, but is catastrophic in J7. In theory cdf could be made to take an argument to unload just a specific dll but, if I remember correctly, it doesn't because back in those early days unloading specific dlls caused all sorts of problems. Did you get the call to jj.dll to work? If so, you will have to live with that and not do the cdf. Please clarify for me if you got JDo to work or not.

Re: [Jgeneral] JHS ipad support
I'm afaid I don't have the time to help in detail now. You are perhaps
biting off too much right now. It is probably a mistake to copy all that
stuff from jijx to jijxipad without really understanding the jijx
framework. Why not focus for now on the smaller task of just adding a
labadvance button to jijxipad. For the experiment us jijx to open a lab.
Then you have the well defined and limited task of adding a button to
jijxipad that calls labnext when called.

Re: [Jgeneral] JHS ipad support
The following assumes you have used jijx to open a lab. To add an advance
button to jijxipad you need to do something like.
add following line in HBS=: section to create the button
'advance'jhb'adv'
add following J def to handle the button event in J
ev_advance_click=: 3 : 'labnext_jlab_ 0'
towards the end in the javascript definition add the js handler

I assume you mean by a labnext button a lab advance button? A choose a lab button would also be needed, and an actual lab choice by the user would trigger the showing of the labnext button on jijxipad, right? Regarding the space key peculiarities of the ipad keyboard, I have discovered a couple of workarounds. On the numeric ipad keypad there is an undo key which can be helpful if you wish to simply enter a list of space-separated numbers: just press the undo key first and then enter the list. On the symbolic ipad key pad there is a redo key which can be used to enter something like `a=: a list of space-separated numbers': on the alpha keypad enter the letter `a', then go straight to the symbolic keypad by way of the numeric keypad, then press the redo key before entering `=: ...' . These are not great alternatives, but they seem to work.

Are you doing this with Jsoftware JUM or with your own server running the latest JHS update? The iPad jijs support is limited but it does work as far as I know. If I remember correctly it is only an editor and doesn't have an action to run the script. Try the following and let me know if it helps. On the iPad jijxipad form press the E button to the right of the input line. This should give you a new window with a jijsipad form for editing. The jijsipad form has a text field for a file name and a button to read the file and a button to save the file. Enter something like abc=:1234 and press the save button. Now switch back to the ijx window and explicitly do a load of the the file. You should see the abc noun has been defined. Does this help? It would be easy to improve this but it would be nice to have some feedback. Probably the main thing to add would be a run button on the jijsipad form. Not sure what you mean by jijxh.

Re: [Jgeneral] JHS screen formatting
The jhs jijs problems stem from the complexity of the html5 contenteditable
control. The html support for this control was new at the time jhs was
developed and unfortunately support (and bugs) varied greatly across the
various browsers. The situation has stabalized and I am convinced that with
some serious effort the problems with jhs jijs could be resolved.
Unfortunately right now this is not a Jsoftware priority. A wonderful
exercise for an interested party.
I use JHS exclusively for my own work and deal with the situation as
follows:
1. for local JHS (files on the same machine as JHS server) I use my editor
of choice (currently gedit because it is pretty much the same across
windows/linux/mac) for script editing and my own dead simple project manager
to handle script loads and opens.
2, for remote JHS I use the new (not yet part of the pacman jhs update) jijs
editor built for the ipad. This editor uses a simple textarea edit control
and although missing syntax coloring behaves nicely. This was initially
driven because the iphone/ipad devices don't support contenteditable at all.
But I have found that for remote editing the simple textarea works nicely,
reliably and is adequate for most needs.
Over the next few weeks I hope to make updates available that will make
these two approaches more available.
Meanwhile if you are using JHS locally I'd suggest using a local editor and
providing a JHS shortcut to do the load as this will likely meet your needs
better than the current JHS jijs form.

Re: [Jgeneral] installation instructions
A lot is assumed in J701 and having forum access can help. What system did you install? I will assume j7 for windows 32 bit. Did the install (running j701a_win.exe) run smoothly to completion? The last window of the install had some hints of what to do next. You probably want to start by running jhs rather than jconsole as it has a GUI interface and is a bit friendlier. The start button j701 program group should have a launch icon for jhs. Clicking it should start a command window that has information text about what to do next. The jhs command window is a server that runs a J session you can access from a browser. Start a browser and follow the instructions in the jhs server window (essentially browse to URL http://localhost:65001/jijx). If this doesn't help, please provide more details and ask more questions.

Re: [Jgeneral] J602 on Intel MacBook: library load failed
I think (but am not sure) that the problem is that J's jnilib (the link between java and the JE) won't work with java 1.6. If you want to pursue this you need to get a java 1.4 (or perhaps 1.5).

Re: [Jgeneral] Will J run on plug computers?
My current feeling is that using such devices as browsers to a J server makes more sense than porting and running J locally. I think the potential usability is much higher, for far less work, and covers a wider range of devices. Have you tried one with the current Jsoftware JHS. No doubt there are problems, but they are worth solving. Put another way: if such devices were in serious and wide use with the J server, then that might be enough interest to justify the extra steps for a port.

Re: [Jgeneral] out of memory using 11!:2999
I wonder if you are just seeing normal J memory allocation. That is, when additional space is required for an array the size of the array is doubled (memory allocation are in factors of 2).

GPL issues are complicated. I don't understand them and get more confused the more I try. I consider it to be more ideological than legal. The problem is the viral nature and where to draw the boundaries.

The operating system was BSV 4004 and was quite different from the IBM offerings at the time. The Siemens machine was very closely related to the RCA Spectra series.

Re: [Jgeneral] Fonts in jwd on Ubuntu
The qscreen results are curious. The 3120 indicates a VERY wide screen even though the 1050 height seems low. And the 212 212 for horizontal and vertical pixels per logical inch seem wrong unless your screen is really tiny. The 212 212 is going to cause Java and J to think they need lots of pixels to draw a character that is readable, the result being extra large characters. In earlier messages Oleg suggested looking at DPI settings and I think it worthwhile to look more closely there at at your general screen configuration. Can you config your system to use a 'normal' screen size (e.g., 1280 1024). This isn't a solution, (especially if it requires temporary use of another screen device) but might narrow down the problem area.

Re: [Jgeneral] J on the iPhone?
We have no plans to port J to the iPhone or similar devices. The way to go with these devices is a web server that provides J execution, state, and display with the device browser as the front end. This is not too difficult to do. The main complications come from trying to support multiple users and issues such as security and resource consumption. Those complications go away if you simply host your own J server that is dedicated to your own use.

[Jgeneral] Failed to get Java metrics
A new j.jar is available that might fix the java metrics problem.
http://www.jsoftware.com/download/j.jar
The previous version did a sleep loop for 1 second waiting for Java gui init
to finish. It seems this wasn't long enough for some environments on the
first run of java. The new j.jar allows 10 seconds.
If you have had the Java metrics problem, please try the new j.jar and
report the results.

Subject: [Jgeneral] Further on Failed to get Java metrics error and
asimple workaround
Several posts last month reported that starting J 6.02 on OSX resulted in
an error message-Failed to get Java metrics. Although this error is a
minor annoyance when running the IDE, it would be potentially very
confusing for end users of standalone applications.
Investigating the problem further, I found that the error occurs the first
time J is started after every reboot. I've only encountered the error on
OSX 10.4 (PPC) and 10.5 (Intel), both running Java SE 5. I had no problem
running on linux (Ubuntu 7 and Fedora 8, Java SE 6). The error does not
occur if any java program is run prior to starting J (including the prior
failed attempt to start J).
As a simple workaround (until either Java on OSX or j.jar is fixed), a
simple splash screen program can be inserted into the jwd script just
prior to the execution of J. With the addition of the splash screen, the
Java metrics error does not occur (even after a reboot) with the cost of a
few seconds additional startup time. The change to the startup isn't
worthwhile for users of the IDE who don't turn their computer off very
often, but if you're distributing a program for use by non-J programmers
it may be worth consideration. The revised start up script and java class
for the splash screen are given below.

The revised jwd script is as follows (the last two lines are a single line
of code):

cd `dirname $0`/..

Re: [Jgeneral] Further on Failed to get Java metrics error and asimple workaround
I doubt the problem has to do with threads. The javametrics are aquired in a
non-AWT loop that sleeps until the AWT thread has settled down and the
required info is available. My quess is that the loop is allowed to time out
to early in Norman's situation. There would be no harm in increasing the
time allowed and when I get a chance I will provide a version that simply
waits longer to see if that fixes the problem. Java initialization from
scratch is a surprisingly long winded process.

It is commandable to do this research, but...
Splashes are annoying. So is it worth replacing one annoyance

It was noticed earlier that there may be an issue with accessing
AWT from main thread.
So maybe this route can be pursued first?

Re: [Jgeneral] install configure J602 under Windows XP
I haven't looked at your problems in detail, but these comments might help.
Study HelpUser ManualInstall page. In particular the section Customized
User Folder.
If you want the standard profile, then I would strongly recommend against
starting J with your own profile. You should start J normally and let normal
mechanisms provide the customization you require.
With luck you will find that a custom install to the folder of your choice
combined with careful modification of profile_template.ijs to create
profilex.ijs will give you what you want.
I would be wary of a multi-user install that has the same user folders for
all users. This is against the intended structure and use. It might be
better to have private user folders and then simple mechanism to provide a
common shared folder.

Subject: [Jgeneral] install configure J602 under Windows XP
The J602 installer for Windows offers three choices none of which is what
I want: I want to install for all users, but NOT in c:\Program Files.
The best I could do was to install as a single user and to select the
program installation directory I wanted, D:\Language\j602\bin\j.exe.
But I do NOT want to keep any user files in
C:\[user]\j602-user
but rather inside the the single Juser directory that I want to specify,
just like I always have before (with recent releases) by means of suitable
configuration files include a profile.ijs -- see below.
I note that the installer did create C:\[user]\j602-user but except for 4
empty subdirectories, that directory is completely empty.
The J program shortcut I use has target
D:\Language\j602\bin\j.exe -jprofile
d:\language\Juser\config6\myprofile.ijs
and starts in the installation directory, d:\language\j602.
The myprofile.ijs referred to above includes:
NB. create SYSTEMFOLDERS
NB. the entry for binary is added in boot.ijs
sep=. PATHSEP_j_
prf=. PROFILE {.~ PROFILE i: sep
add=. 'd:\language\Jaddons'
sys=. prf,sep,'system'
tmp=. 2!:5'JHOME'
usr=. 'd:\language\Juser'
cfg=. 'd:\language\Juser\config6'
hlp=. sys,sep,'extras',sep,'help'
hom=. (0e. { ;prf) 2!:5 'JHOME'
ids=. ;: 'profile system addons temp user config help home'
SYSTEMFOLDERS_j_=: ids ,. prf;sys;add;tmp;usr;cfg;hlp;hom
And the version of startup.ijs in that same d:\language\Juser\config6
includes:
NB. Provide global for environment var JHOME
HOME_z_=: (2!:5'JHOME'),'\'
TEMP_j_=: (2!:5'JHOME')
This startup.ijs is what referred to in the entry
STARTUP=: 'd:\language\Juser\config6\startup.ijs'
in d:\language\Juser\config6\config.ijs.
When I try to start the program using the shortcut as modified, I get
error message: Error and no IDE window for debugging.
What's wrong and how can it be fixed?

Re: [Jgeneral] wd setlocale

completely off base.
The intent of wd'setlocale' is that wdhandler is called in the desired
locale. In the splitter example this would be in the object locale of the
splitter class. There should be no requirement for wdhandler to look at
syslocalec, just as there is no need for it to look as syslocalep.

Here's a pattern for wd setlocale from jsplitter.ijs:
(PID,'_',ID,'_paint')=: paint
(PID,'_',ID,'_mbldown')=: mbldown
(PID,'_',ID,'_mblup')=: mblup
(PID,'_',ID,'_mmove')=: mmove
HWNDC=: wd 'qhwndc ',ID
wd 'setlocale ',ID,' ',coname''
It seems to beat the raison d'etre of wd setlocale:
if it is necessary to create event verbs
for each control instance, that's no better
than before--when such event verbs were defined
in parent form as handlers in control locale:
(PID,'_',ID,'_mmove')=: ('mmove_',ctl_loc,'_')~
what would be really nice, is if it weren't necessary
to define event verbs; wd setlocale should suffice
to tell that for such parent and for such child id
here's the locale (control instance) that would have
the handelrs in the simple form mmove (without PID_ID_):
mmove=: 3 : 0
... do move
)
Maybe it's already there and somebody does not
fully understand something. If it's not there it
should be easy to realize such logic in the main
wdhandeler based on the wdq values.

Up to calling wdhandler is fine.
The problem is in what wdhanlder is calling.
It is currently calling verb:

So it prevents having generic controls without

(PID,'_',ID,'_mblup')=: mblup
(PID,'_',ID,'_mmove')=: mmove

It seems to beat the raison d'etre of wd setlocale:
if it is necessary to create event verbs

than before--when such event verbs were defined
in parent form as handlers in control locale:

what would be really nice, is if it weren't necessary
to define event verbs; wd setlocale should suffice
to tell that for such parent and for such child id
here's the locale (control instance) that would have
the handelrs in the simple form mmove (without PID_ID_):
mmove=: 3 : 0

Maybe it's already there and somebody does not
fully understand something. If it's not there it
should be easy to realize such logic in the main
wdhandeler based on the wdq values.

Re: [Jgeneral] wd setlocale
If wdhandler is called in a child object locale, you would like wdhandler to
just call event. Makes sense.
Analogously, if wdhandler is called in a form object locale, would you like
the option that wdhandler just call event?
The point is that PID and CID are probably not needed and indeed are a
nuisance if called in an object locale.
We can't make the change for forms as too much would break. Perhaps a form
style could indicate this option. Perhaps a setlocale parameter could select
the plain event option. In this case the changes would be to the wd'q'
result and not to the wdhandler definition.
Your point deserves attention. It would be nice if it can be done in a
manner that is backwards compatible, is clean in 603, and doesn't require to
much messing around with 602.

Up to calling wdhandler is fine.
The problem is in what wdhanlder is calling.
It is currently calling verb:
PID_CID_event''
So it prevents having generic controls without
creating every time the cascade of verbs:
PID_CID_event=: event
for each instance.
To fix this, wdhandeler should call simply
event''
if it exists or proceed as it does right now

Re: [Jgeneral] J602 available
To run pacman to update files in a protected folder such as Program Files you need to have permission. You may be able to right click the J icon and select 'Run as Administrator'. Or you may have to actually log on as an admin account an run J there as admin to run pacman. Running XP on a limited account is good practice. This is a little less necessary on Vista as accounts are by default limited, but can fairly easily and visibly boosted to admin when required. Again, I wonder why people install J in program files.

Your limited account is really limited and can't be bumped up to admin by the menu 'run as administrator'. There may be an option for your account that you could turn on that would enable the 'run as admin' but I am not sure. If not, you will have to log on to a admin account to run pacman.

Re: [Jgeneral] If I upgrade to a 64-bit machine
Mapping is all done with cd calls to standard host facilities. The jmf script utilities have not been updated to allow mapping files with more than 2^31 bytes.

I think I understand the problem with that lab on the mac. On both windows and linux the mbopen and mbsave dialogs are nearly identical and have an edit field for a file name.

Re: [Jgeneral] Segmentation fault with j601_64 on Ubuntu 7.10 (64x)
Linux J64 troubles: I am not familiar with the Ubuntu release numbers. Is your system old (2 years), middle aged (1 year), or bleading edge? The problem may be in jconsole. In which case it is likely in one of the libraries it uses or in its readline support. Or the problem may be in libj601.so. It would help a lot if you could test jwd. To do this you will have to find where Java 64 is on your system (you may have to download and install it). When you have Java 64 you will need to edit the jwd script to run it. If jwd works then that shows that the libj601.so works. You can use ldd to see what libraries jconsole is using and perhaps that will give a clue to the problem. cd j601_64 ldd jconsole I would rather track this down in the new j602 beta.

J would be one of the prime uses of the new device. I would be grateful to anyone currently running J6 on a Pocket device to advise me of what to buy. I don't need it to also be a cell-phone or have any other bells and whistles; just a vanilla Pocket PC with the latest operating system would suffice as long as it runs J6 (and Pocket Word, Pocket XL and Microsoft Reader). I would also appreciate it if the J developers could say whether in their opinion they intend to continue to support and develop J for pocket devices, and if so, what minimum specs I should be looking for.

Re: [Jgeneral] J ui -- new files
At first glance the idea of allowing open to open a new file that didn't previously exist is a good idea. This can probably be done by changing the mbopen parameters to remove ofn_filemustexist. I think this works in j.exe but am not sure about j.jar. Perhaps Chris will have a chance to think about this as a change to ijs open. - Original Message - From: Raul Miller [EMAIL PROTECTED] To: General forum general@jsoftware.com Sent: Monday, October 01, 2007 5:48 PM Subject: [Jgeneral] J ui -- new files I have been frustrated with the J new file UI. Example: I am thinking about creating a new script. I am not sure if I have already created it. Let's call this script 'noise.ijs' Possible interaction with J for this case: Control-N wait for window to appear (for example, if my J session was swapped out) move mouse then select File-Save As... (or use platform dependent key sequence) move mouse then click on parent directory icon move mouse then [double] click on user directory name check for 'noise.ijs' If name does not exist: replace 123.ijs with noise hit enter If name does exist: ESC move mouse and close edit window (or system dependent key strokes) Control-O move mouse then [double] click on noise.ijs That's a lot of work what should be a simple operation -- open a script which is probably new on this machine (but might not be). Note also that at this point I have created a bogus empty file which has no relation to what I wanted to accomplish. I could rearrange those steps, by first checking if the file name does exist, but that would not eliminate these bogus files for all cases. This probably leads to some additional steps, such as: Control-O move mouse then click on parent directory icon move mouse then [double] click on Temp directory name find the most recently created numbered file right click on it and delete it ESC I wish I could hit Control-O and if the file name I type in does not exist I get an are you sure? prompt? (Which would either cancel the operation or create the newly named file, depending on how I answer.) I also wonder at the utility of the Delete numbered file popup which shows up at window close time but not at save as some other file name time. It seems to me that logically speaking this popup should appear at file abandonment time -- and Save As... should be treated as one of those times if its new name is different from the old numeric name. Am I overlooking something useful here?

Re: [Jgeneral] debugger start-up
I assme you are in Windows. I have occasionally seen this and agree there is a bug. I have been unable to track it down.

Re: [Jgeneral] usb stick noexec mount in linux
My investigation also convinces me that remount is the only reasonable approach for running J on the stick directly. In some cases it may be better to simply copy the j directory to a user directory, run from there, and copy back at the end if desired and this is quite simple. These are minor problems considering the convenience of having complete J system for several platforms that are quite easily and directly usable. It makes Bill Lam's comment about using a stick instread of a laptop very realistic for certain situations. - Original Message - From: Raul Miller [EMAIL PROTECTED] To: General forum general@jsoftware.com Sent: Friday, July 13, 2007 11:28 AM Subject: Re: [Jgeneral] usb stick noexec mount in linux On 7/13/07, Raul Miller [EMAIL PROTECTED] wrote: On 7/12/07, Raul Miller [EMAIL PROTECTED] wrote: On 7/12/07, Robert Bernecky [EMAIL PROTECTED] wrote: /etc/udev/rules.d/50-udev-default.rules ... /etc/udev/rules.d/85-mount-fstab.rules Note that this approach will make all USB sticks executable (instead of only the one with J on it).

And, unfortunately, automounting under linux has had several implementations with significantly different architectures, so documenting an approach for arbitrary sets of linux users would take some study. Anyways, I think mount -o remount still stands as the simplest approach. -- Raul -- For information about J forums see http://www.jsoftware.com/forums.htm -- For information about J forums see http://www.jsoftware.com/forums.htm
[Jgeneral] usb stick noexec mount in linux
I have been playing with J602 systems installed on a usb stick (thanks to Bill Lam). It works nicely on Windows but I have some questions for linux/unix gurus. The usb stick is automatically mounted by my Suse linux system. It was trivial to copy the J602 system over but I can't run it as it is mounted as noexec. I can manually unmount and remount without the noexec (su required) but this is a nuisance. Is there a way (sudo command) to just change the noexec option after the device has been automatically mounted? -- For information about J forums see http://www.jsoftware.com/forums.htm
Re: [Jgeneral] Profile.ijs comments
The intent is that the J front end (jconsole.exe j.exe et. al.) always define PROFILE and ARGV. They should be defined in the example you give and I am surprised that they aren't. I can't look at this further right now and ask that you run your experiment again. Check both jconsole.exe and j.exe. The later setting of PROFILE if not already set shouldn't be there and is a bit of left over history. - Original Message - From: Sherlock, Ric [EMAIL PROTECTED] To: General forum general@jsoftware.com Sent: Tuesday, June 19, 2007 9:49 PM Subject: RE: [Jgeneral] Profile.ijs comments -Original Message- [mailto:[EMAIL PROTECTED] On Behalf Of Sherlock, Ric In the default profile.ijs, one of the first things done is to set the noun PROFILE_z_ to be the pathname of the default profile.ijs if it is not already defined. My current thinking is that if you were using a custom profile (via -jprofile on the command line) then PROFILE_z_ should be set before the line. if. notdef 'PROFILE' do. PROFILE_z_=: 1!:45'' end. Reading back through some forum archives, another possibility occurs to me. Bill Lam suggests in http://www.jsoftware.com/pipermail/programming/2006-December/004527.html that ARGV should work with -jprofile, because it is injected by J executable before running any script. If this is true then perhaps PROFILE is also supposed to be injected by the J executable? However when I run c:\program files\j601\j.exe -jprofile 18!:4 'z' 18!:5 '' +-+ |z| +-+ 4!:1 ]0 1 2 3 $4!:1 ]0 1 2 3 0 Neither ARGV or PROFILE are defined in the z locale.

Re: [Jgeneral] Re: jconsole - ubuntu 64bit - (v7.04) - unterminatedquotedstring error
A google search for unterminated quoted string indicates the problem is with the shell configuration and is not a problem in J console. You should probably see what you can find there that is relevant to your instalation. One problem area is with bad stuff in your shell rc file. The problem can also show up if the rc file is bad and you have funny stuff in the command line. What exactly are you typing to run jconsole?

Do you get this output immediately on starting jconsole or is it in response to your first input.
