Create and Test Forex Strategies
A namespace is similar to a directory or folder, while pagenames are similar to files.
In DokuWiki you can use namespaces to categorize your pages. For names of namespaces the same restrictions hold as for pagenames.
A default DokuWiki installation comes with built-in namespace: wiki.
You don't need to create namespaces separately; simply create pages with colons in the pagename. The token after the last colon will be the name of the page itself, while all other tokens are namespaces. All namespaces used in your pagename that don't exist already will be created by DokuWiki automatically.
(In DokuWiki pages are created as in every other wiki. Simply create a link to a non existing page, follow this link, and click on Create this page.) Adding pages.
Examples: | |
---|---|
example .example .:example | refers to the page “example” in the current namespace. |
:example | refers to the page “example” in the root namespace. |
..example ..:example .:..:example | refers to the page “example” in the parent namespace |
wiki:example | refers to the page “example” in the namespace “wiki”. The namespace “wiki” is located beneath the root namespace. |
ns1:ns2:example :ns1:ns2:example | refers to the page “example” in the namespace ns2. The namespace ns2 is located beneath the namespace ns1; the namespace ns1 is located beneath the root namespace. |
.ns1:ns2:example .:ns1:ns2:example | refers to the page “example” in the namespace ns2. The namespace ns2 is located beneath the namespace ns1; the namespace ns1 is located beneath the current namespace. |
..ns1:ns2:example ..:ns1:ns2:example | refers to the page “example” in the namespace ns2. The namespace ns2 is located beneath the namespace ns1; the namespace ns1 is located beside the current namespace (i.e. both ns1 and the current namespace are beneath the same parent namespace, wherever according to the root namespace this parent may be located itself). |
.ns1:ns2: | refers to the page “start” in the namespace ns2. The namespace ns2 is located beneath the namespace ns1; the namespace ns1 is located beneath the current namespace. (The default page can be named something other than “start” by adjusting the config:startpage configuration setting.) |
Gotcha: The syntax for relative and absolute internal links is non-unique and complex relative to directory and filename conventions. Paths are absolute if and only if they begin with “/”. Links are absolute if and only if they have a “:” prefix or have no prefix but do have intermediate (or suffix) “:” Links relative to the current namespace may also begin with either “.” or “.:” (“..” or “..:” for parent namespace).
When all pages inside a namespace are removed the namespace logically doesn’t exist anymore. DokuWiki usually deletes the now empty directory as well.
In order to rename a namespace manually you will have to:
data/pages
data/media
(if this exists)data/meta
data/attic
(or move that over as well, if you want to preserve old versions)For example, on a Unix host, you could:
mv /dokuwiki_base/data/pages/old_namespace /dokuwiki_base/data/pages/new_namespace
mv /dokuwiki_base/data/media/old_namespace /dokuwiki_base/data/media/new_namespace
rm -Rf /dokuwiki_base/data/meta/old_namespace
rm -Rf /dokuwiki_base/data/attic/old_namespace
Note that the old_namespace
and/or new_namespace
words may need to be encoded if they are on a non-Latin character set (i.e. Greek, Russian, etc).
However, you will still have lots of junk left around. For example in data/changes.log
, various files under cache (including the .idx
files etc). If possible you could just start from a blank state
as follows (again under Unix) but be warned that this will mean losing all your historical information (i.e. recent changes
):
cat /dev/null > /dokuwiki_base/data/changes.log
rm -Rf /dokuwiki_base/data/attic/*
rm -Rf /dokuwiki_base/data/cache/?
rm -Rf /dokuwiki_base/data/cache/*.idx
rm -Rf /dokuwiki_base/data/cache/purgefile
DISCLAIMER : I understand this is convoluted (and maybe I missed/messed a couple of things you should also do). All in all this is a PITA. You may also use a couple of plugins that are available for (re)building the searchindex for the complete wiki, erasing entire cache and/or old wiki revisions thus avoiding to do this manually.
You can use the third-party PageMove plugin to move each of the pages from the old namespace to the new one. Please consult the documentation to see if this fits your needs.
It is possible to link to a default file of a namespace ending the linkid with a colon: [[foo:bar:]]. To which page the link links is dependent on the existence of certain named files. For [[foo:bar:]] the following pages are checked:
foo:bar:$conf['start'] foo:bar:bar foo:bar
The pages are checked in that order and whatever page is found first will be linked to. Autoplural linking is not done for those links
