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