If you&#39;re lazy, one easy way is to extend &lt;code&gt;generic-mode&lt;/code&gt; to know about your new language:

&lt;http://emacswiki.org/emacs/GenericMode&gt;

I do this a lot for config files for applications that I work with a lot to get decent syntax highlighting.  [Here&#39;s one](http://lists.digium.com/pipermail/asterisk-dev/attachments/20050113/a1304cae/asterisk-mode.obj) I did for the asterisk PBX a long time ago as an example.

I need to package my Python application, its dependencies and Python into a single MSI installer. The end result should desirably be:

 - Python is installed in the standard location
 - the package and its dependencies are installed in a separate directory (possibly site-packages)
 - the installation directory should contain the Python uncompressed and a standalone executable is not required

I use the Boost Test framework for my C++ code but there are two problems with it that are probably common to all C++ test frameworks:

  - There is no way to create automatic test stubs (by extracting public functions from selected classes for example).
  - You cannot run a single test - you have to run the entire &#39;suite&#39; of tests (unless you create lots of different test projects I guess).

Does anyone know of a better testing framework or am I forever to be jealous of the test tools available to Java/.NET developers?

I would like to write an &lt;b&gt;Emacs major mode&lt;/b&gt; for a 4GL.
Can someone show me a tutorial?
As far as I googled I was able to find only this broken:

I&#39;m trying to detect the size of the screen I&#39;m starting emacs on, and adjust the size and position the window it is starting in (I guess that&#39;s the frame in emacs-speak) accordingly. I&#39;m trying to set up my &lt;tt&gt;.emacs&lt;/tt&gt; so that I always get a &quot;reasonably-big&quot; window with it&#39;s top-left corner near the top-left of my screen.

I guess this is a _big_ ask for the general case, so to narrow things down a bit I&#39;m most interested in GNU Emacs 22 on Windows and (Debian) Linux.


How do I set the size of Emacs&#39; window?

Suppose I want to open a file in an existing Emacs session using `su` or `sudo`, without dropping down to a shell and doing `sudoedit` or `sudo emacs`. One way to do this is

    C-x C-f /sudo::/path/to/file

but this requires an expensive [round-trip through SSH][1]. Is there a more direct way?

[EDIT] @JBB is right. I want to be able to invoke `su`/`sudo` to save as well as open. It would be OK (but not ideal) to re-authorize when saving. What I&#39;m looking for is variations of `find-file` and `save-buffer` that can be &quot;piped&quot; through `su`/`sudo`.

When editing HTML in emacs, is there a way to automatically pretty-format a blob of markup, changing something like this:

      &lt;table&gt;
      &lt;tr&gt;
    &lt;td&gt;blah&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;

...into this:

    &lt;table&gt;
     &lt;tr&gt;
      &lt;td&gt;
       blah
      &lt;/td&gt;
     &lt;/tr&gt;
    &lt;/table&gt;


Can emacs re-indent a big blob of HTML for me?

Emacs puts backup files named `foo~` everywhere and I don&#39;t like having to remember to delete them.  Also, if I edit a file that has a hard link somewhere else in the file system, the hard link points to the backup when I&#39;m done editing, and that&#39;s confusing and awful.  How can I either eliminate these backup files, or have them go somewhere other than the same directory?



How do I control how Emacs makes backup files?

I&#39;ve switched computers a few times recently, and somewhere along the way I lost my .emacs.  I&#39;m trying to build it up again, but while I&#39;m at it, I thought I&#39;d pick up other good configurations that other people use.

So, if you use Emacs, what&#39;s in &lt;i&gt;your&lt;/i&gt; .emacs?

Mine is pretty barren right now, containing only:

1. Global font-lock-mode! `(global-font-lock-mode 1)`
2. My personal preferences with respect to indentation, tabs, and spaces.
3. Use cperl-mode instead of perl-mode.
4. A shortcut for compilation.

What do you think is useful?

I&#39;m looking for an elegant way of determining which element has the highest occurrence ([mode][1]) in a JavaScript array. 

For example, in

    [&#39;pear&#39;, &#39;apple&#39;, &#39;orange&#39;, &#39;apple&#39;]

the `&#39;apple&#39;` element is the most frequent one.

I&#39;m using git version 1.5.6.3, and it seems git doesn&#39;t notice a folder&#39;s mode changes

    #create a test repository with a folder with 777 mode
    :~$ mkdir -p test/folder
    :~$ touch test/folder/dummy.txt
    :~$ cd test
    :~/test$ chmod 777 folder/

    #init git repository
    :~/test$ git init
    Initialized empty Git repository in ~/test/.git/
    :~/test$ git add .
    :~/test$ git commit -m &#39;commit a directory&#39;
    Created initial commit 9b6b21a: commit a directory
     0 files changed, 0 insertions(+), 0 deletions(-)
     create mode 100644 folder/dummy.txt

    #change folder permission to 744
    :~/test$ chmod 744 folder/
    :~/test$ git status 
    # On branch master
    nothing to commit (working directory clean)

What does `04000` stand for?

    :~/test$ git ls-tree HEAD folder
    040000 tree 726c1d5f0155771348ea2daee6239791f1cd7731	folder

Is this normal behavior? 

How can I track folder mode changes?

Normally you can execute a Python script for example: `python myscript.py`, but if you are in the interactive mode, how is it possible to execute a Python script on the filesystem?

    &gt;&gt;&gt; exec(File) ???

It should be possible to execute the script more than one time.

I have an WPF application which access windows services, task schedulers on the local machine. 
When I deploy this WPF application and run it without &quot;Run as Administrator&quot; , it fails as it is not able to access the windows services and task schedulers on the local machine. If I run it with &quot;Run as Administrator&quot;, it works correctly.

How do I make my application by default run in admin mode when it is deployed in production?

I&#39;ve been doing a basic program to find the max, min, median, variance, mode etc. of a vector. Everything went fine until I got to the mode.

The way I see it, I should be able to loop through the vector, and for each number that occurs I increment a key on the map. Finding the key with the highest value would then be the one that occurred the most. Comparing to other keys would tell me if it&#39;s a single multiple or no mode answer. 

Here&#39;s the chunk of code that&#39;s been causing me so much trouble. 

    map&lt;int,unsigned&gt; frequencyCount;
    // This is my attempt to increment the values
    // of the map everytime one of the same numebers 
    for(size_t i = 0; i &lt; v.size(); ++i)
        frequencyCount[v[i]]++;
    
    unsigned currentMax = 0;
    unsigned checked = 0;
    unsigned maax = 0;
    for(auto it = frequencyCount.cbegin(); it != frequencyCount.cend(); ++it )
        //checked = it-&gt;second;
        if (it -&gt;second &gt; currentMax)
        {
            maax = it-&gt;first;
        }
        //if(it -&gt;second &gt; currentMax){
        //v = it-&gt;first
    
    cout &lt;&lt; &quot; The highest value within the map is: &quot; &lt;&lt; maax &lt;&lt; endl;

The entire program can be seen here. http://pastebin.com/MzPENmHp
