4 Using ikiwiki with the [[rcs/git]] backend, some interesting things can be done
5 with creating mirrors (or, really, branches) of a wiki. In this tip, I'll
6 assume your wiki is located on a server, and you want to take a copy with
9 With the configuration described here, you can commit local changes to the
10 version on the laptop, perhaps while offline. You can browse and edit the
11 wiki using a local web server. When you're ready, you can manually push the
12 changes to the main wiki on the server.
14 ## simple clone approach
16 First, set up the wiki on the server, if it isn't already. Nothing special
17 needs to be done here, just follow the regular instructions in [[setup]]
18 for setting up ikiwiki with git.
20 Next, `git clone` the source (`$REPOSITORY`, not `$SRCDIR`)
21 from the server to the laptop.
23 Now you need to write a setup file for ikiwiki on the laptop. Mostly this
24 is standard, but a few special settings are needed:
26 * Configure a cgi wrapper as usual, but configure the git wrapper to
27 be written to the `post-commit` hook of the git clone, rather than the
28 usual `post-update` hook.
30 git_wrapper: /home/user/foo-wiki/.git/hooks/post-commit
32 * By default, ikiwiki pulls and pushes from `origin`. This shouldn't be
33 done on the laptop, because the origin may not be accessible (when the
34 laptop is offline). Also, commits made on the laptop should stay there,
35 until manually pushed, so that the laptop can serve as a staging area.
37 Make sure you have ikiwiki 2.11 or better installed, and set:
41 * You can optionally enable to the [[plugins/mirrorlist]] plugin,
42 and configure it so that each page links to the corresponding page on the
45 Now just run `ikiwiki --setup wiki.setup --getctime` and you should be
46 good to go. (You only need the slow `-getctime` option the first time you
47 run setup.) If you have taken your `wiki.setup` file from an existing
48 wiki, you may need to change certain parameters to adapt to the paths
49 on your laptop, a few examples:
51 srcdir: /home/user/foo-wiki
52 destdir: /home/user/public_html
54 url: http://foo-wiki.localhost
55 libdir: /home/user/foo-wiki/.ikiwiki
57 TMPDIR: /home/user/tmp
61 Now, set up a [[web_server|dot_cgi]] on your laptop, if it doesn't
62 already have one. You can also skip that step if you want only to
63 render the wiki and not allow edition, in which case you'll want the
66 # disable CGI, unless you want to get really funky
70 You can also direct people to the main server for web edition there.
72 Use standard git commands to handle pulling from and pushing to the server.
74 Note that if changes are pulled from the server, you will need to manually
75 update the wiki, with a command such as `ikiwiki --setup wiki.setup --refresh`.
76 If you'd like it to automatically update when changes are merged in, you
77 can simply make a symlink `post-merge` hook pointing at the `post-update`
80 ## bare mirror approach
82 As above, set up a normal ikiwiki on the server, with the usual bare repository.
84 Next, `git clone --mirror server:/path/to/bare/repository`
86 This will be used as the $REPOSITORY on the laptop. Then you can follow
87 the instructions in [[setup by hand|/setup/byhand]] as per a normal ikiwiki
88 installation. This means that you can clone from the local bare repository
89 as many times as you want (thus being able to have a repository which is
90 used by the ikiwiki CGI, and another which you can use for updating via
93 Use standard git commands, run in the laptop's bare git repository
94 to handle pulling from and pushing to the server.
