| == Tutorial - Cloning a repository == ''(This page is part 2 of 9 of the [[Tutorial]] series. Previous part is [[TutorialInstall]], next part is [[TutorialHistory]])'' You have followed TutorialInstall to install Mercurial already, right? Good! In Mercurial, we do all of our work inside a [[Repository|repository]]. A repository is a directory that contains all of the source files that we want to keep history of, along with complete histories of those source files (inside the .hg directory — see UnderstandingMercurial). The easiest way to get started with Mercurial is to use a repository that already contains some files and some history. To do this, we use the {{{clone}}} command. This makes a [[Clone|clone]] of a repository; it makes a complete copy of another repository so that we will have our own local, private one to work in. Let's clone a small "hello, world" repository hosted at selenic.com: {{{ $ hg clone http://www.selenic.com/repo/hello my-hello }}} If all goes well, the {{{clone}}} command prints this (Mercurial 1.4): {{{ requesting all changes adding changesets adding manifests adding file changes added 2 changesets with 2 changes to 2 files updating to branch default 2 files updated, 0 files merged, 0 files removed, 0 files unresolved }}} We should now find a directory called {{{my-hello}}} in our current directory: {{{ $ ls my-hello }}} Inside the {{{my-hello}}} directory, we should find some files, together with the .hg directory, that contains Mercurial's private data (basically the history of the repository plus various state information — see [[Repository]] for more information): {{{ $ ls -a . .. .hg Makefile hello.c }}} These files are exact copies of the files from the [[Tip|tip]] revision of the default branch in the repository we just cloned. '''Note:''' in Mercurial, each repository is self-contained. When you clone a repository, the new repository becomes an exact copy of the existing one at the time of the clone, but subsequent changes in either one ''will not show up'' in the other unless you explicitly transfer them, by either [[Pull|pulling]] or [[Push|pushing]]. By default, `hg clone` checks out (see [[Update]]) the [[Tip|tip]]most [[Revision|revision]] of the repository's ''default branch'' into the repository's [[WorkingDirectory|working directory]]. To see which revision is currently checked out, we can use the [[Parent|parents]] command: {{{ $ cd my-hello $ hg parents changeset: 1:82e55d328c8c tag: tip user: mpm@selenic.com date: Fri Aug 26 01:21:28 2005 -0700 summary: Create a makefile }}} At this point, we can start examining some of the history of our new repository, by continuing to TutorialHistory. ---- CategoryTutorial |
