Yes, you can comment lines out of Git config files using `#` or `;`.

From [the documentation](http://git-scm.com/docs/git-config#_syntax):

&gt; **Syntax**
&gt;
&gt; The syntax is fairly flexible and permissive; whitespaces are mostly ignored. The `#` and `;` characters begin comments to the end of line, blank lines are ignored.

I&#39;ve just recently switched to a Mac from Ubuntu. I was disappointed that mac doesn&#39;t have the convenient `sudo apt-get` in Ubuntu. I&#39;ve heard that I should use homebrew but I&#39;m not exactly sure what homebrew or macports does? 

What is the difference/usage of homebrew, macports or other package installation tools?

While writing [this answer][1], I had to match exclusively on linebreaks instead of using the `s`-flag (`dotall` - dot matches linebreaks).  

The sites usually used to test regular expressions behave differently when trying to match on `\n` or `\r\n`.

I noticed

 - Regex101 matches linebreaks only on `\n`   
([example][2] - delete `\r` and it matches)  


 - RegExr matches linebreaks _neither_ on `\n` _nor_ on `\r\n`  
and I can&#39;t find something to make it match a linebreak, except for the `m`-flag and `\s`   
([example][3])

 - Debuggex behaves even more different:  
in [this example][4] it matches only on `\r\n`, while  
[here][5] it only matches on `\n`, with the same flags and engine specified

I&#39;m fully aware of the `m`-flag (multiline - makes `^` match the start and `$` the end of a line), but sometimes this is not an option. Same with `\s`, as it matches tabs and spaces, too.    

My thought to use the unicode newline character ([`\u0085`][6]) wasn&#39;t successful, so:

 1. Is there a failsafe way to integrate the match on a linebreak (preferably regardless of the language used) into a regular expression?
 2. Why do the above mentioned sites behave differently (especially Debuggex, matching once only on `\n` and once only on `\r\n`)?

Match linebreaks - \n or \r\n?

I have a `http.proxy` line on my repository configuration file that I would like to &#39;turn on and off&#39; easily without having to remember and type again the whole configuration every time I&#39;m behind or free from this proxied connection.

Another possibility would be to use this repository configuration file when I&#39;m behind the proxy and when not, use a global/local configuration file without any proxy setup.


Can I comment out a line in a .git/config file?

I know that it&#39;s possible to set per-repo configs which override the user-level config (i.e. `/path/to/my/repo/.gitconfig` overrides `~/.gitconfig`). Is it possible to set git configs which override the user-level settings for all child folders of a given folder? I.e., I have

    |--topLevelFolder1
    |--\
    |   ---.gitconfig_override
    |--\
    |   ---childFolder1
    |       \---[...]
    |--\
    |   ---childFolder2
    |       \---[...]

And I want the settings defined in `.gitconfig_override` to apply in `childFolder1` and `childFolder2`.

My motivation for this is as follows: I have a work laptop which I also use in my spare time for personal projects. All my work code is nested within a single folder. When I push to work git repos, I need to do so with my work persona - work login instead of name, and work email. When I push to my own personal (github) repos, I want to do so with my real name and personal email.

Other possible solutions I&#39;ve thought of (and problems):

* Create separate users for &quot;work&quot; and &quot;play&quot;, set their user-level settings appropriately, and log in as the appropriate user when I switch context (hassle, plus I could easily forget to switch)
* Create a script that searches for git repos inside &quot;workFolder&quot;, and adds/updates their .gitconfig files to hold the appropriate details (if I create a repo and forget to run the script before pushing, I will push as the wrong person)
* &quot;hack&quot; git such that every time it creates a repo, it checks the filepath and, if appropriate, updates the .gitconfig file (complicated, messy, and almost certainly The Wrong Way To Do It - plus, I wouldn&#39;t have the first clue how to go about it!)

I checked [this question][1], which only seems to contain solutions for single repos, not multiple. Hopefully someone will see this question who missed that one!

Merge git repo into branch of another repo

My team is using Bitbucket for our git repository and we&#39;ve recently starting using the pull request functionality for code reviews.  It works fine on the first review, but if it goes through multiple iterations (that is, changes are made and pull request updated), I would like to see a link with just the new changes that were made since the last code review.

I looked into the &quot;compare&quot; functionality but the UI looks like it can only compare between branches.  Is there a simple way to get a diff between two commits?

Every time I start Git Gui on a particular project I get this message:

&gt; This repository currently has approximately 320 loose objects.

![enter image description here][1]

I then proceed to click *Yes*, and I get this dialog:

![enter image description here][2]

The thing is, when I open Git Gui again, **I get the exact same message**, again about 320 loose objects! It&#39;s as if clicking *Yes* had no effect at all.

I create a `package.json`, I run `npm install`, it works alright. It creates a `node_modules` directory in my root folder (which I can change by using `--prefix` option). However, I don&#39;t like underscores all that much. I want to change the name of the directory NPM downloads the modules to. I want it to be named `nmods` or `node-modules` or something like that.

Bower can do a similar thing by reading the `directory` property inside a `.bowerrc` file in the current dir. Is there a way to do the same with NPM?

What would be the best way to store DB config (username, password) in an open source app that runs on node.js / Express? Two specific questions:

1. Shall I put it into a separate config.js file in `/lib` folder, for example, and never include it into the master repository that is publicly available on GitHub?

2. To inlcude the config, is it as simple as `require(&#39;./config.js&#39;)` from the file that needs it or is there a better way of doing it?

PS sorry if the questions seem a bit simple or not so well formulated, but I&#39;m just starting :)

Best way to store DB config in Node.Js / Express app

I have multiple property files that I want to load from classpath. There is one default set under `/src/main/resources` which is part of `myapp.jar`. My `springcontext` expects files to be on the classpath. i.e. 

    &lt;util:properties id=&quot;Job1Props&quot;
		location=&quot;classpath:job1.properties&quot;&gt;&lt;/util:properties&gt;

    &lt;util:properties id=&quot;Job2Props&quot;
		location=&quot;classpath:job2.properties&quot;&gt;&lt;/util:properties&gt;

I also need the option to override these properties with an external set. I have an external config folder in `cwd`. As per spring boot doc config folder should be on classpath. But its not clear from doc if it will only override the `application.properties` from there or all the properties in config. 

When I tested it, only `application.properties` gets picked up and rest of properties are still picked up from `/src/main/resources`. I have tried supplying them as comma separated list to `spring.config.location` but the default set is still not being overriden.

How do I make multiple external config files override default ones?  

As workaround I currently used `app.config.location` (app specific property) which I supply through the command line. i.e 

    java -jar myapp.jar app.config.location=file:./config

 and I changed my `applicationcontext` to 

&lt;util:properties id=&quot;Job1Props&quot;
		location=&quot;{app.config.location}/job1.properties&quot;&gt;&lt;/util:properties&gt;

    &lt;util:properties id=&quot;Job2Props&quot;
		location=&quot;{app.config.location}/job2.properties&quot;&gt;&lt;/util:properties&gt;

And this is how I make separation between file and classpath while loading Application. &lt;br/&gt;
**EDITS:**

    //pseudo code

    if (StringUtils.isBlank(app.config.location)) {
    			System.setProperty(APP_CONFIG_LOCATION, &quot;classpath:&quot;);
    }

I would really like not to use the above workaround and have Spring override all external config files on the classpath like it does for the `application.properties` file.


Spring Boot and multiple external configuration files

I have 4 states: **dashboard**, **dahboard.main**, **dashboard.minor**, **login**.
dashboard is abstract and it is a parent state for .minor and .main states.
Below is my code:

    .state(&#39;dashboard&#39;, {
            url: &quot;/dashboard&quot;,
            abstract: true,
            templateUrl: &quot;views/dashboard.html&quot;,
            resolve: {
                auth: function ($q, authenticationSvc) {
                    var userInfo = authenticationSvc.getUserInfo();
                    if (userInfo) {
                        return $q.when(userInfo);
                    } else {
                        return $q.reject({ authenticated: false });
                    }
                }
            },
            controller: &quot;DashboardCtrl&quot;,
            data: { pageTitle: &#39;Example view&#39; }
        })
        .state(&#39;dashboard.main&#39;, {
            url: &quot;&quot;,
            templateUrl: &quot;views/main.html&quot;,
            controller: &quot;DashboardCtrl&quot;,
            data: { pageTitle: &#39;Main view&#39; }
        })

As you see in dashboard state I have resolve option. By this I would like to redirect user to login page if he is not authorized. For this reason I use special **authenticationSvc** service:

    .factory(&quot;authenticationSvc&quot;, [&quot;$http&quot;, &quot;$q&quot;, &quot;$window&quot;, function ($http, $q, $window) {
        var userInfo;

        function login(email, password) {
            var deferred = $q.defer();

            $http.post(&quot;/api/login&quot;, { email: email, password: password })
                .then(function (result) {
                    if(result.data.error == 0) {
                        userInfo = {
                            accessToken: result.data.accessToken
                        };
                        $window.sessionStorage[&quot;userInfo&quot;] = JSON.stringify(userInfo);
                        deferred.resolve(userInfo);
                    }
                    else {
                        deferred.reject(error);
                    }
                }, function (error) {
                    deferred.reject(error);
                });

            return deferred.promise;
        }
        function getUserInfo() {
            return userInfo;
        }
        return {
            login: login,
            logout: logout,
            getUserInfo: getUserInfo
        };
    }]);

I check auth value in **config** :

    .run(function($rootScope, $location, $state) {
        $rootScope.$state = $state;
        $rootScope.$on(&quot;routeChangeSuccess&quot;, function(userInfo) {
            consol.log(userInfo);
        });
        $rootScope.$on(&quot;routeChangeError&quot;, function(event, current, previous, eventObj) {
            if(eventObj.authenticated === false) {
                $state.go(&#39;login&#39;);
            }
        });
    });

But unfortunately when I go to my website root or dashboard state I get an empty page. What is wrong with this code? Thanks!

Angularjs ui-router. How to redirect to login page

I exploring a few options to setup kafka and I knew that the Zookeeper has to be up and running to initiate a kafka.


I would like to know how can I find the below.


1) hostname and port for my zookeeper instance---I checked the zoo.cfg and I could only find the ClientPort not the hostname, will hostname be the hostname of my box??


2) To check if ZooKeeper is up and running---I tried to do a `ps -ef | grep &quot;zoo&quot;` I could not find anything. May be I am using a wrong key word to search??

Any help would be really appreciated?
