As you are not trying to move the files around in the tree, you should be able to just checkout the directory:

    git checkout master -- dirname


If there are no spaces in paths, and you are interested, like I was, in files of specific extension only, you can use 

    git checkout otherBranch -- $(git ls-tree --name-only -r otherBranch | egrep &#39;*.java&#39;)

To copy the directory *without tracking it*:

    git restore --source master dirname

In my case this simplest solution to get files from the origin branch directory was:

 - **origin** - remote repository alias(origin by default)  sourceBranchName
 - **branch** with required files in directory 
 - **sourceBranchDirPath** - relative/absolute path to the required directory with

files

    git checkout origin/sourceBranchName -- sourceBranchDirPath

Example:

    git checkout origin/validation_fix -- src/test/java/validation/

&gt; Result was all files from **origin/validation_fix** branch by
&gt; **src/test/java/validation/** relative path in the draft
&gt; mode(uncommited)



Is it possible in C++ to replace part of a string with another string?

Basically, I would like to do this:

    QString string(&quot;hello $name&quot;);
    string.replace(&quot;$name&quot;, &quot;Somename&quot;);

But I would like to use the Standard C++ libraries.

What is the difference between a pure virtual function and a virtual function? 

I know &quot;Pure Virtual Function is a Virtual function with no body&quot;, but what does this mean and what is actually done by the line below:

    virtual void virtualfunctioname() = 0

How do I copy all files in a directory from another branch? I can list all of the files in that directory by doing 

    git ls-tree master:dirname

I can then copy all of the files individually by doing

    git checkout master -- dirname/filename

However, using wildcards has so far been a total fail.  This does nothing: 

    git checkout master -- dirname/*.png

 Though I guess I can use a bash script to do that, there has to be an easier way, right?

Is there an efficient workflow to mirror a project that is mainly hosted on bitbucket using Hg, to github?

Mirroring a HG project from Bitbucket to Github

In Git I can do this:
&lt;pre&gt;
1. Start working on new feature:
$ git co -b newfeature-123  # (a local feature development branch)
do a few commits (M, N, O)

master A---B---C
                \
newfeature-123   M---N---O

2. Pull new changes from upstream master:
$ git pull
(master updated with ff-commits)

master A---B---C---D---E---F
                \
newfeature-123   M---N---O

3. Rebase off master so that my new feature 
can be developed against the latest upstream changes:
(from newfeature-123)
$ git rebase master

master A---B---C---D---E---F
                            \
newfeature-123               M---N---O
&lt;/pre&gt;
&lt;br /&gt;

I want to know how to do the same thing in Mercurial, and I&#39;ve scoured the web for an answer, but the best I could find was: [git rebase - can hg do that][1]

That link provides 2 examples:&lt;br /&gt;
1. I&#39;ll admit that this: (replacing the revisions from the example with those from my own example)
&lt;pre&gt;
hg up -C F  
hg branch -f newfeature-123  
hg transplant -a -b newfeature-123 
&lt;/pre&gt;
is not too bad, except that it leaves behind the pre-rebase M-N-O as an unmerged head and creates 3 new commits M&#39;,N&#39;,O&#39; that represent them branching off the updated mainline.

Basically the problem is that I end up with this:
&lt;pre&gt;
master A---B---C---D---E---F
                \           \
newfeature-123   \           M&#39;---N&#39;---O&#39;
                  \
newfeature-123     M---N---O
&lt;/pre&gt;
this is not good because it leaves behind local, unwanted commits that should be dropped.


2. The other option from the same link is 
&lt;pre&gt;
hg qimport -r M:O
hg qpop -a
hg up F
hg branch newfeature-123
hg qpush -a
hg qdel -r qbase:qtip
&lt;/pre&gt;
and this does result in the desired graph:
&lt;pre&gt;
master A---B---C---D---E---F
                            \
newfeature-123               M---N---O
&lt;/pre&gt;
but these commands (all 6 of them!) seem so much more complicated than 
&lt;pre&gt;
$ git rebase master
&lt;/pre&gt;

I want to know if this is the only equivalent in Hg or if there is some other way available that is simple like Git.

Hg: How to do a rebase like git&#39;s rebase

I&#39;m a Git user trying to use Mercurial.

Here&#39;s what happened: I did a `hg backout` on a changeset I wanted to revert. That created a new head, so hg instructed me to merge (back to &quot;default&quot;, I assume). After the merge, it told me I still had to commit. Then I noticed something I did wrong when resolving a conflict in the merge, and decided I wanted to have everything as before the `hg backout`, that is, I want this uncommited merge to go away. On Git this uncommited stuff would be in the index and I&#39;d just do a `git reset --hard HEAD` to wipe it out but, from what I&#39;ve read, the index doesn&#39;t exist on Mercurial. So how do I back out from this?

I started cloning an SVN repository using the git-svn&#39;s clone operation.  After about 6 hours of importing (it&#39;s a big repo), my computer went and slept on me.  Is there a way to resume the operation without redoing all of the initial work?

I want to associate custom metadata with a `git commit`.  Specifically to record a review ID from a code review but it could be anything.  Tags seem a natural way to do that but I expect to have a review for every commit and I don&#39;t want to clutter `gitk` with tons of tags.  Is there some other mechanism to add custom metadata?  Can I make certain tags invisible?  If I could tell `gitk` not to display tags matching some pattern or RE, that would likely work but I don&#39;t see a way to do that.

Can I add metadata to git commits? Or can I hide some tags in gitk

Like a lot of people, I&#39;d like to customize the ugly `input type=file`, and I know that it can&#39;t be done without some hacks and/or `javascript`. But, the thing is that in my case the upload file buttons are just for uploading images (**jpeg|jpg|png|gif**), so I was wondering if I could use a &quot;`clickable`&quot; image which would act exactly as an input type file (show the dialog box, and same $_FILE on submitted page).&lt;br /&gt;
I found some workaround [here][1], and [this interesting one][2] too (but does not work on Chrome =/).

What do you guys do when you want to add some style to your file buttons? If you have any point of view about it, just hit the answer button ;)

Unless I&#39;m missing something, it seems that none of the APIs I&#39;ve looked at will tell you how many objects are in an `&lt;S3 bucket&gt;/&lt;folder&gt;`. Is there any way to get a count?

I&#39;m trying to make a script to list all directory, subdirectory, and files in a given directory.  
I tried this:

```python
import sys, os

root = &quot;/home/patate/directory/&quot;
path = os.path.join(root, &quot;targetdirectory&quot;)

for r, d, f in os.walk(path):
    for file in f:
        print(os.path.join(root, file))
```

Unfortunatly it doesn&#39;t work properly.  
I get all the files, but not their complete paths.

For example if the dir struct would be:

&lt;pre&gt;
/home/patate/directory/targetdirectory/123/456/789/file.txt
&lt;/pre&gt;

It would print:

&lt;pre&gt;
/home/patate/directory/targetdirectory/file.txt
&lt;/pre&gt;

What I need is the first result. Any help would be greatly appreciated! Thanks.

Python list directory, subdirectory, and files

Why must a copy constructor&#39;s parameter be passed by reference?

Why should the copy constructor accept its parameter by reference in C++?

    $from = &quot;\\something\1 XLS\2010_04_22\*&quot;
    $to =  &quot;c:\out\1 XLS\2010_04_22\&quot;
    copy-item $from $to -Recurse 

This works if `c:\out\1 XLS\2010_04_22\` does exist . Is it possible with a single command to create `c:\out\1 XLS\2010_04_22\` if it doesn&#39;t exist?

I have an object which has many bufferedimages in it, I want to create a new object copying all the bufferedimages into the new object, but these new images may be altered and i don&#39;t want the original object images to be altered by altering the new objects images.

is that clear?

Is this possible to do and can anyone suggest a good way to do it please?

In bash I need to do this:

1. take all files in a directory 

2. copy them into an existing directory

How do I do this? I tried `cp -r t1 t2` (both t1 and t2 are existing directories, t1 has files in it) but it created a directory called t1 inside t2, I don&#39;t want that, I need the files in t1 to go directly inside t2. How do I do this?

I&#39;m currently working on a branch and want some commits to merge into other branches:

        a-b-c-d-e-f-g (branchA)
       /
    --o-x-x-x-x-x-x-x-x-x-x (master)
       \
        x-x-x-x-x (branchB)

(Letters denote commits, and the &quot;x&quot; are irrelevant commits.)

However I noticed that it would be a good idea to pool some commits. I want to &quot;concatenate&quot; commit a, d, e and g into one patch and commit it to master. Commits b and f should go as one commit to branchB. Is there a good &#39;git&#39;-ish way to achieve it?


Reordering of commits

I&#39;ve been working on code checked out from the development line and discovered that the changes made might be breaking changes and need to be moved to an experimental branch before committing to the main dev tree. However, I don&#39;t have the experimental branch checked out and I don&#39;t want to lose the changes that have already been made.

Is there a way to commit the changes in the working folder to a different branch than originally checked out?
