Emacs inside of gedit? - emacs

After years of experimentation with editors, the fact is I prefer them as minimal as possible. I never use fancy features and the full-feature IDE's become bloated, heavy, and slow. Of course, when I do something that pretty much requires a specific IDE (like Android dev and Eclipse) I have no problems using it. But most of the time, I use gedit for programming.
However, I like many Emacs commands, and I want to use them occasionally. Is there a way to embed Emacs inside of gedit? For instance, I envision pressing alt-q (or whatever combo) and Emacs mode is enabled, and from then on all my key presses in the current tab do Emacs commands. I press alt-q again, and it turns off. This would allow me the best of both worlds. Anything like this exist, or do I need to write this plugin myself?

No.
I've seen discussion of embedding of Emacs in other applications in the past, and the consensus is that even that's not feasible, let alone what you're suggesting.
You'd be better off identifying what gedit does that makes you want to use it instead of Emacs, and extending Emacs to make it do that, too. (There can't be that much --- gedit doesn't do much.) The extra features can just sit there and wait for you, and you'll find it easier to locate and use them if you're comfortable in Emacs-mode already.
(On top of all the other advantages of Emacs, you gain the ability to use the same editor you use in a windowed environment on the terminal --- a huge advantage.)
Or maybe yes . . .
You can use the External Tools plugin of gedit (look for it in Preferences). Add a new command, bind it to the key you want, and use this script:
#!/bin/sh
FILE_NAME=$GEDIT_CURRENT_DOCUMENT_PATH
emacs $FILE_NAME
If you want it to open in the currently-running Emacs, replace emacs with emacsclient, and add the following to your .emacs:
(server-start)

This is kind of backward. Why don't you just use Emacs and stay away from all the extra bells and whistles? It'd probably be easier to coax emacs to emulate gedit than the other way around.

If gedit (a) can be scripted to launch another application with the current file as an argument, and (b) will notice if the file is modified on disk and offer to reload it, then you would have a workaround.

First of all, this is not a question on emacs vs vim. I use eclipse IDE for programming and I intend to continue using it. Having read many advantages of emacs and vim, especially the ability to do almost anything without using the mouse, I want to use a similar typing/editing scheme in my eclipse IDE; I'm aware that there are plugins available for eclipse to change the editing style to emacs or vim (emacs+, vrapper to name a few..).
Since I plan to continue using eclipse, the various advantages of vim and emacs like small memory foot print, vim/elisp scripting, availability on different platforms, configurablity etc are all lost. I want to import only the text editing scheme to eclipse and master it while keeping all of eclipse's features.
So, I would like to have an objective comparison of the benefits/disadvantages of only the text editing styles of emacs and vim.
EDIT: the reason I cannot move away from eclipse is because my company uses a customized version of eclipse which has specific plugins and dsls to interact with our product(hardware)

Please note that Vim is not an IDE (a search will bring up various discussions of this topic), therefore this dichotomy does not exist. You can very well use both Vim (for text editing) and a real IDE (for debugging, source code browsing, etc.), in parallel. A simple "launch current file in Vim" integration is quickly done, and you've already noted that there are several plugins that bring the basic key bindings (but not the huge customizability) into the IDE.
Also, it strikes me as odd that you have no preconception of Vim vs. Emacs yet. Most people breathe and live their key bindings so much that they desire them in their IDE, too; you just seem to "have heard" about those advantages, but haven't experienced them yet.
My advice: Use your IDE for work (as you have to, anyway), and try out Vim (as well as Emacs) in parallel, maybe for recreational tasks, a little scripting, blogging, whatever. You can then see for yourself whether you'll "get hooked" on one of them, or maybe the IDE will just work out fine for you. Also, time will tell whether a simple integration is sufficient, or whether you want something tight and deep like the Eclim project.
I can only tell something about vim, I have used emacs once in a while, but it doesn't seem to be compatible with me. Although I really like scheme which is a lisp dialect. Vimscript is a horror to program in, but it is possible.
The main feature vim offers is that it adds structure to text beyond the syntax of your language. You can manoeuvre, edit and transform your text with vim's movements. These are at the heart of vim and have to be learned well. This in combination of modes, makes vim a powerful tool for text editing.
On the other hand, for code editing, vim needs some modifications to be useful. You will a considerable amount of configuration. Most people keep their vim configuration in a fire and bullet-proof safe, so they will not lose their painfully built stack of options, plugins and other configurational paraphernalia. That is including me. A vimrc is quite personal. Emacs is easier to configure. I could pick it up much faster.
You have to learn a tremendous amount of knowledge to even be able to use it. Emacs is much easier, you can use it at once. My first encounter with vim was being not be able to leave the damn program, whatever I did. My second encounter, was carefully hitting i and the type some text and quickly hit :wq. But somewhere later I suddenly wanted to tame it.
Vim has macro's, which make a lot of text transforming tasks fun. E.g. this removes al spaces at the end of a line, something I sometimes run to stop the nagging of pylint about spaces:
qs:g/ $/s///g<CR>#sq
You should read this as: record a macro in register s, replace globally all spaces at the end with nothing, apply macro in register s, stop recording. When hitting:
#s
This macro will run endlessly, until you are satisfied. I still want to find one, which stops after he hunted the last space. This makes vim fun, it is a little language with one letter commands. You can combine letters together:
4f,d$
This means find he 4th comma (,) and delete (d) the line from there till the end ($). That makes it quite attractive.
I would personally go for vim, but you have to try the editors out. They have different philosophies and one of those will bite you and the other will seem reasonable. I don't believe you will find many people, who uses both and mastered both. They are both usable as code editor.
I still have emacs on my wishlist, maybe I will swap.
I would suggest reading these answers as they contain a good amount of differences between the two (although a lot of the benefits mentioned don't matter for you). I strongly suggest just trying them out.
A big difference that you will notice is that Vim uses modes, which makes it have a high initial learning curve, while Emacs is modeless, and you can use it like a normal text editor (notepad), but with added functionality. And his is where your style/preference matters. I personally don't like holding control down to move around in Emacs, where in Vim, you escape to normal mode and use hjkl to move around.

Emacs (Multi)Term vs Xterm vs Console & TMUX

I'm an Emacs user trying to learn a software tool that is best run from a terminal. The default set-up to get the most out of that tool is to use xterm for interaction and call Vim for editing. One could simply replace Vim with Emacs in this setup, but then one would spend most of the time working outside of Emacs in an Xterm.
I figured out there is (Multi)Term-mode in Emacs, but it is really hard to find out about its pros and cons. So I have the following questions:
[Without X11]: Why or when would anybody use Emacs (Mutli)Term instead of Console & TMUX (or GNU Screen)?
[With X11] How does Emacs (Multi)Term compare to Xterm?
Obviously speed is one criteria for comparison, but I'm sure there are other.
You'd use Emacs term over tmux/screen if you're more familiar with Emacs and already use it for many other things and/or if you spend more time in Emacs than in the terminal.
Emacs's Term is much less sophisticated and much less reliable than xterm. But it works within Emacs so if you live in Emacs, it might be a good option.
Note that you may also prefer to use Emacs's M-x shell functionality, which gives you a command line without giving you an actual terminal emulator. That means that the commands are edited in Emacs before being sent to the underlying command-line program, so all the usual Emacs editing can be used there (and the history manipulation as well as command completion is performed by Emacs as well, which can be great, or can be disappointing (e.g. if the completion needs info which Emacs does not have)).

Is there a .emacs file available to make its keybindings behave like any modern IDE?

I learned programming with GUI editors such as Notepad++, Gedit, Netbeans and so on, so I'm used to some keybindings common in almost all of these programs (and some others like LO Writer, etc).
Is there any place where I can find a .emacs file that makes it work like that, so I can have all its power without spending half of my life in learning its keybindings or configuring it?
You might try ErgoMacs which was built to modernize Emacs. I haven't tried it since when I found it I already had too many of my own keybindings to switch, but if I were starting over, I'm pretty sure I would use it.
cua-mode remaps emacs to use the key bindings that most other programs use. It is built in to emacs and you can enable it in your .emacs with:
(cua-mode t)
It depends a bit on what you mean. There are ways to make Emacs use keyboard shortcuts that are standard in Windows, as e.g. pointed out by ataylor. However, when you say you want it to behave more like an IDE, it seems that you're not only interested in text editing keybindings (such as, moving the point, copy and paste, marking a region, etc.), but specifically for the functionality offered by IDEs: compiling, management of code projects, deployment, code refactoring, etc.
But Emacs is not an IDE. It's a text editor. Okay, it really is a lisp interpreter based around a visual model of text buffers.
As such it can do many tasks that IDEs do, but out of the box, IDEs do many of the tasks mentioned above better because they are made for these tasks. Since Emacs is just a lisp interpreter, a lot of people have written extensions to its core functionality, in form of so called "modes". So, yes, by installing the right modes on top of a vanilla Emacs you can make it a pretty powerful tool that can compete with IDEs.
But that doesn't go without spending half of my life in learning its keybindings or configuring it. Well, half your life is a bit of a stretch. Emacs has a steep learning curve, that's true, but it's worth it -- because it is not an IDE. It's more than that.
If you're not willing to learn new stuff, than maybe you might want to take a moment and reconsider whether programming really is for you. Because the IT landscape changes very quickly all the time. Maybe in five years, Java is dead and no-one uses Eclipse any more. But you can be pretty sure of one thing: Emacs will still be around.
Okay, the last paragraph was total FUD, so ignore it. But seriously, learning new keybindings is not as hard as you think. And it doesn't take thaaat long either. You could re-configure and re-assign completely to your own liking in Emacs, but why not give the standard keybindings a chance?

How to Make Eclipse More Like Emacs

I am very familiar with emacs--and I realize that there is nothing that it cannot do--but there are some things that it does not do well or efficiently. So, being between projects I am open to the idea of switching to a full-featured IDE such as Eclipse.
With muscle-memory being what it is, I would like to make Eclipse as emacs-like as possible. I have already discovered the excellent Emacs+ plugin which gets me about halfway there. However, I am still missing the following features of emacs which I routinely rely upon:
shell: It's not just a shell, it's also a buffer.
occur: Search->File... is close to what I want, but I just want it to search the current file--which might be a text file, a logfile, or a shell buffer, or whatever.
align-regexp: This awesome little command in emacs helps me make files more readable, and alignment helps with keyboard macros.
What plugins would you recommend to solve these issues? Are there any other emacs features you miss in Eclipse or plugins you would recommend?
Please, no emacs/vi zealots asking why on Earth I would do such a thing.
For the shell you have WickedShell
Ctrl+F is enough to trigger a Search within the current file. (does not create a new buffer with matched lines)
Only Mark Occurrences is about highlighting occurrences, but that is not as advanced as the Emacs function.
Formatter options can emulate "align-regex" function, as described here.
Preferences -> Java -> Code Style -> Formatter.
Click 'Edit' on the profile (you may need to make a new one since you can't edit the default).
In the indentation section select 'Align fields with columns'.
Then, in your code Ctrl+Shift+F will run that formatter.
I can confirm Brian's suggestion (Emacs key-bindings). What I do to resolve this dilemma is to use both Emacs and Eclipse simultaneously. They are both very good at reporting external changes to files so there is minimal chance of tromping on edits (but it can happen). More to the point, you can leverage the strengths of both tools without having to give up either one. The combination of using both tools and Eclipse having Emacs key-bindings makes this quite satisfactory for me.
IIRC (It's been a while since I've used eclipse) eclipse has a "use Emacs key-bindings" mode. I believe that there's also the option to tell eclipse to use emacs as its own editor...

How to change emacs config in Lisp In A Box

I have been a programmer for a decade now, but I believe this is the first time I've ever asked a question on a forum. I just can't figure this out and can't find the answer already online.
I am trying to turn on CUA mode so that emacs is more bearable for a windows user (normal copy paste functions). I am running Windows 7 and installed emacs through the Lisp In A Box package. I understand that I need to add a line to my .emacs file or init.el file. I'm not sure which, but I can't find either in my Lip In A Box install directory. The emacs package install also did not come with any tutorials or help files, so its really hard to pick this up.
I am stuck, any help is greatly appreciated!
The .emacs can be found by looking at the answers to this similar question.
Regarding documentation and tutorials, it looks like the link you provided for "Lisp in a Box" says:
If you are new to Emacs, it is
recommended that you read the Emacs
Tutorial which you can access from
with Emacs by going to the Help menu,
or by typing Control-h, letting go,
and hitting t. A more extensive manual
is also available from the Help menu,
or on the web at
http://www.gnu.org/software/emacs/manual/.
Which makes it sound like the manual is there, and certainly the tutorial (I made bold the directions to get to the tutorial).
As far as other places to get information, there is a collection of screencasts on the wiki.
Your question doesn't specify whether or not you what to add to your .emacs to activate CUA mode. You can check out the CUA mode documentation on the wiki (which has links to the manual). The minimal installation is just adding this to your .emacs: (cua-mode t).
For GNU/Emacs, you can choose to use any one of the following three file names as the start-up configuration file:
${HOME}/.emacs
${HOME}/.emacs.el
${HOME}/.emacs.d/init.el
It would probably be a good idea to decide on one of the three options and then stick to it - the first one seems to be the most widely used one. In any case, ${HOME} stands for your home directory -- which is likely to be different from the Lisp In A Box install directory!
Coming from a Unix tradition, Emacs understands ~ (tilde) as an abbreviation for your home directory, so you can visit the .emacs file by typing:
C-x C-f ~/.emacs [ENTER]
(Note that the capital C is Emacs standard notation for a combination of the CTRL key and a second key, i.e. here you press CTRL-x CTRL-f which stands for "find-file" and will then ask you for a file name in the bottom part of the Frame (aka mini-buffer).)
If these are your first customizations, you will just see an empty buffer. Enter
;; start CUA mode every time Emacs starts
(cua-mode t)
and save the buffer with C-x C-s.
Next time you start Emacs, CUA mode should be turned on automatically.
What the others have told you is true: Simply adding (cua-mode t) to your dotfile would be sufficient. HOWEVER: Lisp in a box' Emacs doesn't load this file by default.
Therefore, be sure to edit the shortcut so that it does load the dotfile. This is important, because otherwise you would get weird behavior, where you would add the correct line to the dotfile, start emacs, and then not get cua mode. That would suck.
The reason it does this is to ensure that it starts a vanilla emacs everytime, instead of finding, say C:/_emacs and loading that instead, giving you another user's customizations and confusing you.
The flag for not loading an init file is -q or --no-init-file. Also make sure that --no-site-file is not there.
(I realize that this is an old post, but I found this while looking for something related, and I don't want people walking away frustrated over something that doesn't work.)
