I have one repository with multiple projects how do I give each project it’s on repository with the existing history?

When I started with Mercurial about a year ago I created one repository called SandBox to put all my projects in it, now about a year later I realize that wasn’t very smart choice I have 19 project in it some of them are big. I would like to give each project its own repository also keeping the history. Is there an easy way I accomplish this?

Take a look at the Convert extension: https://www.mercurial-scm.org/wiki/ConvertExtension

What you actually need is --filemap: https://www.mercurial-scm.org/wiki/ConvertExtension#A--filemap

Well, consider a project with the following structure (in bitbucket):

$ find hgmultiproject
hgmultiproject
hgmultiproject/proj2
hgmultiproject/proj2/mysndfile
hgmultiproject/proj1
hgmultiproject/proj1/myfirstfile
hgmultiproject/proj3
hgmultiproject/proj3/mythirdfile

This project has this log:

You can extract the projects using the Convert extension with the --filemap option.

How to do it? First, you should create a filemap file. In this case, the content should be:

rename proj1 .
exclude proj2
exclude proj3

The first line will move everything inside the proj1 dir to the root of the new repository. The second line will remove the proj2 dir from the new repository, and the third line will remove the proj3.

To use it, just call this way:

$ hg convert --filemap proj1filemap hgmultiproject/ extracted-proj1

Now, enter the new repo:

$ cd extracted-proj1/

It has no working copy...

extracted-proj1 $ ls

y but you just need to update:

extracted-proj1 $ hg update
1 updated files, 0 merged files, 0 deleted files, 0 nonresolved files
extracted-proj1 $ ls
myfirstfile

And the new log is...

extracted-proj1 $ hg log

You should follow these steps for each project of your repository.
