Adventure with Emacs

Is there any Emacs user to give me some hints about this program. I wish to use it for Web development, and i reed that i need Nxhtml mode. I can't find this package in ofical repos nor in AUR?

There is a little thing that bothering me:
When i run shell in Emacs it don't work nice: there is no completions for second word, sudo pacma and when i press <TAB> x2 it says: "No completions of pacma."
Again, not a direct answer to your question, but there are a few terminal emulators for emacs. See this Emacs Wiki page for a complete list:
http://www.emacswiki.org/emacs/CategoryShell
And for something completely different, you can always try eshell.
Now that I think of it, I'm not sure I get completions on the second word (e.g., sudo pacm...) when I use bash in urxvt. I'll have to look into that.

Replacing a string of character by another one with emacs

Hello,
With Vim, I had something like this in my setup (tex.vim in ftplugin)
imap <buffer> ... \ldots
imap <buffer> « \og
imap <buffer> » \fg
imap <buffer> " \textquotedblleft
imap <buffer> ¢ \textquotedblright\
imap <buffer> € \EUR
imap <buffer>~ $\sim\
imap <buffer> // \\
imap <buffer> /np \newpage
Currently, I am trying emacs, and would like the same setup. I have searched the web, but with no luck. Indeed, I've just found the following code (and made some modifications to try it) :
(defun replace-string-pairs-region (start end mylist)
"Replace string pairs in region."
(save-restriction
(narrow-to-region start end)
(mapc
(lambda (arg)
(goto-char (point-min))
(while (search-forward (car arg) nil t) (replace-match (cadr arg)) )
) mylist
(defun replace-chars (start end)
"Replace "..." by "\ldots" and other similar chars"
(interactive "r")
(replace-string-pairs-region start end '(
("..." "\ldots")
;("<" "<")
;(">" ">")
But it doesn't work.
Does anyone know how could I replace "..." by "\ldots" and other things like that with Emacs ?

Thank you a lot for your answer, but my problem was not to replace "..." by "\ldots" after typing it, but how could I replace "..." by "\ldots" while I am typing it, just after I finished to push the last dot.
I have tried to set it up with the abbrev mode, but it seems to work only for words. So for example, if I enter the word such as, say, "arch", then it replace it automatically by "archlinux" after pressing the space key. I won't have to replace the string manually, it does it automatically with the abbreviation mode of Emacs. Here is an example of what I am talking about :
(abbrev-mode t) ; completion automatique
(global-set-key (quote [tab]) (quote dabbrev-expand))
(setq default-abbrev-mode t)
(define-abbrev-table 'global-abbrev-table '(
("..." "\ldots" t)
("arch" "archlinux" nil)
But my problem is, it doesn't work for "...", just for words. Of course, I could do it manually with the shortcut you wrote, but it would be nice to make it work automatically. Is there a way to do so ?
If you don't understand what I am talking about, try Vim, copy "imap <buffer> ... \ldots" in your .vimrc, and Vim will replace all "..." by "\ldots" while typing. I am sure I can do it with Emacs, I just don't know how.

Sync ical help with emac and macpro?

hello out there.... my son has an emac...we subscribe to fam plan .mac.... want to sync his calendar with mine (i have mac pro laptop). he does not have leapard(not compatible with emac i am told...which stinks bty!). can he sync his ical with mine? or visa versa? thanks!

Syncing is really just for one person with multiple machines so that their calendar moves with them. However, you can Publish and Subscribe to each others calendars.
Do this on both machines:
Select the calendar in the list at left and choose Publish from the Calendar menu. Choose the options which apply to you, but I do recommend the one "Publish changes automatically". Once you have clicked OK and the calendar is Published successfully, you can choose to send a mail to the other person in the next dialog.
When you get the mail, you'll see a link to subscribe to the other person's calendar. Follow through the options in iCal, this time ensuring you choose "Auto Refresh: Every ... " at the bottom. When you click OK, the calendar will appear in Subscriptions and will be in your calendar view unless you uncheck it.

Keymapping problem when working with emacs and openbox

I have an apple keyboard and I had to do some remapping of the keys to make the mod-4 key the first key to the left of the space bar for when working with Emacs. The below script worked fine when I was using the dwm window manager, but after switching to openbox I have found that instead of swapping keycodes between the option and command keys, only the command key seems to be working since the initial openbox command-space doesn't work when pressing option-space.
One odd thing I noticed, was on the new setup when I click run `showkey` and press the option and command keys I get 56 and 125 respectively, but these keys don't work at all when inserting them into the below script instead of the 64 and 133.
I must admit I created the script below by continually tweaking it until it worked so there could be a much better way of doing it.
//.xmodmap
### capslock => ctrl
xmodmap -e "clear Lock"
xmodmap -e "add Control = Caps_Lock"
### switch alt and command
xmodmap -e "keycode 64 = Alt_L"
xmodmap -e "keycode 133 = Meta_L"
### remap of mod 4
xmodmap -e "clear Mod4"
xmodmap -e "add Mod4 = Super_L"
** Update: The Alt key is not being swapped with the command key, but is not just a duplicate. So no M-x can be done by both Alt-x and Command-x

How do I upgrade to 10.4 and... is wireless internet possible with eMac?

Hi all,
thanks for answering my last question about browsers: now using Camino and is way better than anything else...
So, so more puzzles:
1) I have 10.3.9 and need to upgrade to 10.4. A friend just told me I can do it for free via updates but I don't believe him as I can't find it. What's the solution?
2) Is it possible to get wirless net with eMacs? If so, what setting do you use?
Thanks all!

Tiger install DVDs are in short supply. Tiger is no longer available at the Apple Store *but may be available for $129 by calling Apple Phone Sales @ 1-800-MY-APPLE (1-800-692-7753)*. For other sources, do a Google search for MA453Z/A (10.4.6), MA190Z/A (10.4.3) and M9639Z/A (10.4) . Also look on eBay. Be sure & buy a retail version (black with silver X) and not a model specific version (gray) (See Can I use another Mac's system restore disc on my Mac? ). Expect to pay (possibly a lot) more than the Apple list price of $129.
Also check these web stores: http://www.lacomputercompany.com/cgi-bin/rpcart/index.cgi?command=dispitem&type= sku&sku=19521 http://www.allmac.com/shop/index.php?cPath=5_10003
Possible Alternative if you are currently using Panther 10.3 – Do a Google search for Tiger 10.4 Upgrade DVD . It will upgrade your 10.3 to 10.4, but it doesn’t contain the full retail Tiger installer. Should be cheaper than the retail Tiger install DVD.
After you install the base 10.4.x, update to the final Tiger version 10.4.11. Here's the link for the 10.4.11 combo update http://support.apple.com/kb/TA24901?viewlocale=en_US
Look at this link Mac OS X v10.4 Tiger Installing Software Support Page
http://www.apple.com/support/tiger/install/
You can also download the Tiger Installation and Setup Guide
http://manuals.info.apple.com/en/TigerInstall_SetupGuide.pdf
When you upgrade the OS, do it via Archive & Install. See About the Archive and Install feature http://support.apple.com/kb/HT1710
Be sure to select Preserve Users & Settings. Also, repair permissions before and after the install.

Shell Scripts: "Open [ALL] With" Emacs

Hi All,
I'm trying to figure out a way to open ALL shell scripts (for which I use the extension ".sh") with emacs (launched in the terminal) by default.
I've made some progress towards this goal, but am stuck on the last step. Here's what I've done:
[1] I copied an Apple Script (from here: http://hints.macworld.com/article.php?story=20031027142625782) to create an Application (which I've called "Emacs_open_with.app"), that when launched with a file, will open it in emacs in the terminal.
[2] I can make Emacs_open_with.app the default launch app for a individual shell script by right-clicking -> Open With -> Other... -> Emacs_open_with.app (+ check the box "Always Open With). However, doing this will only make it the default app for that single shell script, not for all of them, as I desire.
[3] Normally, one can associate an application with a file extension, such that any file with that extension will be launched by default by this associated application, by: Right-clicking a file -> Get Info -> Open With -> Other... -> [DESIRED APP] (+ check the box "Always Open With) -> Change All... -> Click Continue when the pop-up appears which asks "Are you sure you want to change all similar documents to open with the application...". However, this does NOT work for Emacs_open_with.app; as soon as I click continue, the drop-down menu which I had used to select "Emacs_open_with.app" changes back to another, different Application.
Any idea about how best to tackle this problem? Thanks for your help!

Hi Darth,
Thanks for your hint! Nevertheless I think it's something more profound, since there's no error etc. For example, should I have the path wrong I assume that OWB would return me some kind of an error when it doesn't find the .sh-file? Isn't there any log-file to see whether the command was executed? It seems like the execution of the User Defined element would be skipped altogether.
Cheers,
IlmariNo, if you don't give an absolute path OWB will not return any error, it just wont do anything at all...

Bicyclerepair with emacs

bicyclerepair is a python refactoring (and more) helper. I wanted to try it with emacs, i installed it from aur and updated .emacs as it's recomended:
;; pymacs
(autoload 'pymacs-load "pymacs" nil t)
(autoload 'pymacs-eval "pymacs" nil t)
(autoload 'pymacs-apply "pymacs")
(autoload 'pymacs-call "pymacs")
(pymacs-load "bikeemacs" "brm-")
(brm-init)
However i get the following error. Any ideas?
Debugger entered--Lisp error: (error "Pymacs loading bikeemacs...failed")
signal(error ("Pymacs loading bikeemacs...failed"))
error("Pymacs loading %s...failed" "bikeemacs")
pymacs-load("bikeemacs" "brm-")

The solution was:
1. python-mode-1.0 should be loaded in emacs
2. cp ~/bicyclerepair-0.9/ide-integration/bikeemacs.py /usr/lib/python2.4/site-packages/bike/
3. replace the loading with: (pymacs-load "/usr/lib/python2.4/site-packages/bike/bikeemacs" "brm-")
I get the menu, but the refactoring (for example rename or find references) does not work...
Ideas?

Wireless keyboard and mouse with emac

Hi,
Does anyone know whether the new wireless keyboard and mouse will work with eMac without built in bluetooth, and USB 1.0?
Should I use a USB 2.0 dongle or a USB 1.0 dongle.
Any help would be very appreciated.
thanks

That is how I use my macbook. When I start up in the moring, I turn the mouse, keyboard and monitor on first, I then hit the power button on the macbook and immediately close the lid. The macbook will then boot up on the external display. Just in case you allow the macbook to go to sleep, you need to go to allow bluetooth devices to wake the computer. You set this in the bluetooth system prefs.

Using Video Adapter with eMac

I've searched all over and cannot find any information on this, so any help would be greatly appreciated.
I would like to send video from my eMac to my TV. I purchased the Apple Video Adapter and an RCA cable. I have the adapter plugged into the computer, and the cable plugged into the adapter and the TV. I restarted the computer. The TV (on its video setting) shows static with the adapter plugged in; if I take it out, it goes black, so clearly some signal is passing through. However, I cannot figure out how to get the eMac to recognize the new "display".
The discussions on the subject mention using a "detect display" fuction. I don't see anything called "detect display" in the display preferences. I do have it set to show the displays in the menu bar, and the drop-down menu only shows the eMac and its resolutions. The preferences, also, only gives me the info for the eMac.
Am I missing something? Is there a setting I need to change? Should I assume the adapter is defective (I gather this has happened to others)?
Thanks in advance for your help!
eMac 700 MHz Mac OS X (10.4.3)

I don't think the problem is at the TV's end, as it's clearly getting some sort of signal on the video setting I'm using (there's static when it's connected to the computer, and nothing when it's not). The problem is that the computer doesn't see that it's connected to another display.
Something I realized, comparing computers (we also have a Mini)--the Mini's display preferences window has a "detect displays" button that the eMac's doesn't. They're both running 10.4.3. Any ideas (anyone?) why the eMac's missing it?
Thanks again!

Printer Sharing with eMac, iMac, and iBook not working

Hello, everyone. I hope you guys can help me out with this:
I have an Epson Stylus CX4600 hooked up to my eMac via USB. My eMac prints fine with it. The eMac is getting its internet via an Ethernet wire going downstairs into my Linksys Router, which sends my Shaw internet to my iBook, my iMac, and my eMac.
I want to allow the iMac and iBook to access the printer over the network directly, so I can just print from those computers and have it come out the eMac printer.
I've looked at many articles on this. So far I've installed the drivers on all computers, plus they can all network to each other over File Sharing, so they are connected.
But I haven't been able to print yet. The most I've been able to do is get the files I try to print from the iBook and iMac to show up on the eMac, in its printer queue. Only it didn't show up for a LONG time. And when it did, the jobs automatically stopped and everytime I clicked start, it would automatically switch back to stopped again. The files would not print.
At this point, I want to get the iBook connected to it first. If I can do that, I'll try the iMac. But the iBook is first priority. I've tried making it connect to the Printer using IPP (IP Printing), and the result was... what I explained in the above paragraph. I also tried just ordinary Printer Sharing, but it said something close to this:
"Unable to locate eMac.local, Unknown host."
That hardly makes sense, because at that time I also tried getting the iBook connected to the eMac over File Sharing which worked. For some reason, the "eMac.local" and "iMac.local" files don't show up in my Network thing when I connect to them, or even when they're not connected. HOWEVER, I think they did at one point. I could swear I saw "eMac.local" and "iMac.local" in the Servers folder in the Network section of the iBook at one point. But it's no longer there.
Please help. I've described my problem as well as possible. What a long post. If there's any way to make my eMac, iMac, and iBook be able to print through my Epson Stylus CX4600 at any time directly, then I'll do it.
Help!

Yes. I did say that my eMac, iMac, and iBook are all
connected to the internet and networked to each other
over the Linksys router. I believe the router is
still on factory settings because we never really
"set" or programmed anything with it.
Mac OS 9.2.2 on the iMac, Mac OS X 10.4.8 on the
other two. IP addresses?
192.168.1.100 is what I would use to connect to the
eMac from the other computers.
This is the eMac's IP, correct? Did you type it into Network, or was it assigned by the router's DHCP?
192.168.1.101 is what I would use to connect to the
iBook from the other computers.
This is the iBook's IP, right? Again, fixed or DHCP?
192.168.1.102 is what I would use to connect to the
iMac from the other computers.
Same for this IP.
The iBook, as I've said, is wired. No wireless
connections to speak of.
Okay. Now, if the router is handing out IP addresses via DHCP, what range was it configured for? My Linksys, for example, is configured to hand out IPs in the range 192.168.0.10 to 192.168.0.254. It has the IP 192.168.0.1, so the IPs 192.168.0.2 through 192.168.0.9 are available for me to hand out as fixed IPs. If I was to hand out 192.168.0.100 as a fixed IP, the router's DHCP server would have a potential problem, as it might hand out that address too, and only one device can have a particular IP address on a particular network. If your router is handing out 192.168.1.100, .101, and .102 via DHCP, you could and probably do have a conflict if you've got those addresses set up as fixed IPs. In particular, if you have anything else on the network, including Bonjour-enabled devices such as printers, you're likely to have a conflict.
Best way to resolve a conflict, if any:
1 set all the Macs to either DHCP, or if fixed IPs are required, to a fixed IP outside the range of the DHCP range on the router. (Or you could just turn off DHCP on the router.)
2 check the router to be sure that DHCP is set the way you want it, and the DHCP pool is what you think it is.
3 shut down the Macs.
4 turn off the router, wait 30 seconds, turn it back on.
5 turn the Macs back on, one at a time.
On my Linksys, the way to set the DHCP pool is simple:
1 log into the router. (My router IP: 192.168.0.1. Yours would be 192.168.1.1.) Hit the 'Setup' tab. Verify the gateway IP. (Should be the router's IP. If it's not, something very strange is happening.) Verify the start of the DHCP pool. Verify that DHCP is on (or off, as you want). Verify the end of the DHCP pool. (My start is 192.168.0.10, and there are 245 IPs in the pool, so the end is 192.168.0.254. If I changed the number of IPs to 200, the end of the pool would be 192.168.0.209, and I'd be able to set the IPs 192.168.0.200 to 254 as fixed IPs if I wanted.) If your router allows for IPs to be reserved, you can set up reserved IPs for one or more of your Macs. (A reserved IP is an IP the router holds for a specific device. The network card in each computer has a specific MAC address; if that address is registered with the router, then every time that computer is turned on and connected it will get the IP that was reserved for it... so long as that IP is in the DHCP range and DHCP is turned on. Think of it as a fixed IP without your having to actually fix the IP.)

Using with eMac

I have an eMac with USB 1.1, which i believe can't be updated to 2.0. At the moment I have a 3rd gen iPod which connects via Firewire and it all works fine. I'm considering upgrading to a new iPod, for the capacity, but I was wondering whether anyone has experience of using the new iPod with USB 1.1? Will it just be a case of taking a very long time to put 50GB onto it, but after that it will just be a minor annoyance when i put small amounts of new stuff on it each time I update it? Or is it basically not worth getting a new iPod if you haven't got USB 2.0?

Will it just be a case of taking a very long time to put 50GB onto it<<<</div>
USB2 is 480Mbps and USB1 is 12Mbps. These are BITS per second figures. The rates for BYTES per second are 48MBps and 1.2MBps, respectively. My math says 17 minutes for 50GB with USB2 and a really really long time with USB1.

Screen sharing not working with eMac lab after 3.2 update

Screen sharing no longer functions after applying the 3.2 update in our eMac labs running 10.4.10 and PPC processors. However, it still functions in our iMac labs running 10.4.10 Intel processors. Before update, I was able to screen share with all the computers in the lab. After the update, I am only able to share with one single computer at a time. Not very useful anymore for teachers to use for demonstrating purposes at our school. It definately had something to do with the update since it was working moments before the update. Please help before I have to call Apple regarding this issue. Again, it only seems to affect screen sharing across PPC eMac computers, not Intel based computers.

Through much testing at our schools, we determined that the problem lies with the update and the admin machine running ARD. If the admin machine is less than a G5 (doesn't matter if it is intel or PPC), ARD will not screen share with multiple computers (more than 3 machines) at a time. If you have a G5 admin machine, you probably will not experience this problem. Apple has yet to contact our district regarding any options for fixing the problem. We are currently in the process of shuffling computers to make sure there is a G5 admin machine in every lab to run ARD. However, I still think Apple needs to recognize this as a problem with their update. Screen sharing is a great tool for teaching class and it is too bad that with the current 3.2 update, it breaks the ability to use it with "older" G4 macs. Hence, that is why your eMac screen sharing is not working anymore. I can only hope for a prompt update to ARD to remedy this situation.

Problem using ddd with emacs

Dear all,
I am using emacs in conjunction with ddd to debug C codes on my laptop
I normally enter gdb commands on the tty in emacs, watch the position in the source code in emacs and look variable states in ddd.
For some reason I can not enter gdb command on emacs's tty. It is as if ddd would not receive them. But, in turn if I enter gdb commands directly in ddd, I do get a copy of the command and its output on emacs tty.
I call ddd like this:
ddd -fullname
I tried different alternative way to call ddd (--tty, --tty -fullname, --tty -fullname --gdb)
So I went through some test in order to track down the problem.
1) If I start ddd from a standard shell (gnome-terminal), I am able to send commands to ddd
2) In emacs if I use gdb instead of ddd, I am able to send commands to gdb through the tty
3) I copied the config file from my office machine, where the interplay between ddd and emacs works, but the communication problem between emacs and ddd remains.
emacs version is emacs-23.1-5
ddd version is ddd-3.3.12-1
I currently have no idea on how to solve my problem.
Any idea ?
Best regards,
Hakim

EntityFacade class is very simple and it uses a static EntityManager object. Here the code:
public class EntityFacade {
     private static EntityManager em = Persistence.createEntityManagerFactory("ElectroManager").createEntityManager();
     private static Logger logger=Logger.getLogger(EntityFacade.class);
     public static void insertCliente(Cliente c)
          logger.debug("Inserisco cliente nel db: " + c);
          em.getTransaction().begin();
          c.setId(getNextIdForTable("Cliente"));
          em.persist(c);
          em.getTransaction().commit();
If I call the method from inside a main it works well, so I think the problem is not the classpath neither the URL in the persistence.xml. However the URL is:
<property name="toplink.jdbc.url" value="jdbc:derby:c:/programmi/ElectroManager/db/electroManager"/>
I use the latest build version of TopLink.
Thanks.

How to debug Java adventure with jdb

Hi,
I'm learning J2ee and I'd like to use and debug
Java adventure. I tried to find some information but found nothing.
What I tried to debug , is to start the j2ee server by adding the following options into the bin/asadmin.bat file:
-Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n
This it doesn't work because the j2ee server is started with the javaw.exe virtual machine. So I'm stuck here.
My first question: 1- what visual debugger is great to debug J2ee apps ??
I'd like to known what are the steps to:
2- how to start the j2ee server in order to attach the jdb or a visual
debugger ?
3- when starting the j2ee server, what do i have to do in order to step
into the code source of Java adventure and follow function calls ?
4- how do I have to start the jdb to attach to the J2ee server ?
5- Any useful tip to debug J2ee apps ! :-)
Thanks in advance !

Hi,Hello
I'm learning J2ee and I'd like to use and debug
Java adventure. I tried to find some information but
found nothing.
What I tried to debug , is to start the j2ee server by
adding the following options into the bin/asadmin.bat
file:
-Xdebug
ug
-Xrunjdwp:transport=dt_socket,address=8000,server=y,sus
end=nThat looks OK.
This it doesn't work because the j2ee server is
started with the javaw.exe virtual machine. So I'm
stuck here.javaw.exe implies you are on a win32 machine. The default
debugging transport on win32 is shared memory... but you specify
a socket connection on the debugee command line above. This
means you need to specify sockets on the debugger side as well.
For example:
jdb -connect com.sun.jdi.SocketAttach:hostname=localhost,port=8000
Note the port number (8000) matches the value you specified
when starting the debugee.
>
My first question: 1- what visual debugger is great
to debug J2ee apps ??For a list of debugging tools, check this web page:
http://java.sun.com/products/jpda/using.html
Many of these products work well in a J2EE environment.
Most of them are either free, or come with an introductory
"try before you buy" offer.
I'd like to known what are the steps to:
2- how to start the j2ee server in order to attach
the jdb or a visual
debugger ?You are on the right track with the flags/options you
mentioned.
3- when starting the j2ee server, what do i have to
do in order to step
into the code source of Java adventure and follow
low function calls ?The code you want to examine needs to be compiled
with the "-g" flag added to the javac command line.
When -g is specified, javac will save information
in the .class files that is used later during debugging.
4- how do I have to start the jdb to attach to the
J2ee server ?See above...
For more coverage on this topic, refer to:
JPDA Connection and Invocation Details
http://java.sun.com/j2se/1.4.2/docs/guide/jpda/conninv.html
5- Any useful tip to debug J2ee apps ! :-)That is a bit outside the scope of this forum... sorry.
Any useful tips will depend on what J2EE app server you
are using. Most of the well-known servers come with
a debugging guide. For example, take a look at:
Debugging J2EE Applications in the SunOne Application Server
documentation:

Using a Solarmonkey Adventurer with MacBook Air (2010)

Can anyone tell me if you can buy a power attachment for the Macbook Air that has a USB connection at the other end?
I have just bought a Solarmonkey Adventurer from Powertraveller.com, this is a solar powered charger that has multiple adapters to charge all sorts of gadgets, ie: ipod, iphone, ipad, GPS, camera's etc etc .... I doesn't come with an adapter for the MacBook Air but it would need the standard end piece the connects to the computer but with a USB at the other end.
Can anyone help?
Cheers
Sally

The end connection of your power device would tend to indicate that it's output is around 5 volts, which is far below the voltage requirement for the Air. As well, the devices you mention are far less demanding of wattage as well.
Simple answer... No, there is no USB to MagSafe connector, adapter, or cable available, nor would it likely work anyway, because of the aforementioned voltage/wattage issue.
