## DokuWiki
Toolkit provides DokuWiki API for Gemini.
Allows to simple deploy new apps or make existing website mirror
### Examples
* [β-Doku](https://github.com/YGGverse/bdoku) - DokuWiki Satellite for Gemini Protocol
### Reader
Read DokuWiki and convert to Gemini
``` php
$reader = new \Yggverse\Gemini\Dokuwiki\Reader(
// optional regex rule set array
);
```
#### Reader::getRules
#### Reader::setRules
#### Reader::getRule
#### Reader::setRule
Get or change existing regex rule (or just skip by using build-in set)
``` php
echo $reader->setRule(
'/subject/ui',
'replacement'
);
```
#### Reader::getMacroses
#### Reader::setMacroses
#### Reader::getMacros
#### Reader::setMacros
``` php
echo $reader->setMacros(
'~my-macros-key~',
'~my-macros-value~',
);
```
#### Reader::toGemini
Convert DokuWiki text to Gemini markup
As wiki has lot of inline links, to make converted document well-readable, this method does not replace links with new line `=>` macros, but uses inline context: `Name ( URL )`. This model useful with `Reader::getLinks` method, that for example appends all those related links to the document footer.
If you don't like this implementation, feel free to change it by `Reader::setRule` method!
``` php
echo $reader->toGemini(
file_get_contents(
'/host/data/pages/index.txt'
)
);
```
#### Reader::getH1
Get document title
``` php
$gemini = $reader->toGemini(
file_get_contents(
'/host/data/pages/index.txt'
)
);
echo $reader->getH1(
$gemini
);
```
#### Reader::getLinks
Get document links
``` php
$gemini = $reader->toGemini(
file_get_contents(
'/host/data/pages/index.txt'
)
);
echo $reader->getLinks(
$gemini
);
```
### Filesystem
Provides methods for simple and secure interaction with DokuWiki file storage
``` php
$filesystem = new \Yggverse\Gemini\Dokuwiki\Filesystem(
'/host/data' // storage location
);
```
#### Filesystem::getList
Return simple array of all files in storage
``` php
var_dump (
$filesystem->getList(
'hello:world'
)
);
```
#### Filesystem::getTree
Return all files under the storage folder in tree format
``` php
var_dump (
$filesystem->getTree(
'hello:world'
)
);
```
#### Filesystem::getPagePathsByPath
Return pages under the given data directory
``` php
var_dump (
$filesystem->getPagePathsByPath(
// absolute path to target data directory (e.g. Filesystem::getDirectoryPathByUri)
)
);
```
#### Filesystem::getDirectoryPathByUri
#### Filesystem::getPagePathByUri
Return absolute path to stored page file
``` php
var_dump (
$filesystem->getPagePathByUri(
'hello:world'
)
);
```
#### Filesystem::getDirectoryUriByPath
#### Filesystem::getPageUriByPath
Return page URI in `dokuwiki:format`
``` php
var_dump (
$filesystem->getPageUriByPath(
'/full/path/to/page.txt'
)
);
```
#### Filesystem::getMediaPathByUri
Return absolute path to stored media file
``` php
var_dump (
$filesystem->getMediaPathByUri(
'hello:world'
)
);
```
#### Filesystem::getMimeByPath
Return file MIME if path match storage item
``` php
var_dump (
$filesystem->getMimeByPath(
'/full/path/to/page.txt'
)
);
```
#### Filesystem::getDataByPath
Return file content if path match storage item
``` php
var_dump (
$filesystem->getDataByPath(
'/full/path/to/page.txt'
)
);
```
#### Filesystem::isPath
Check path exist and match storage item
``` php
var_dump (
$filesystem->isPath(
'/full/path/to/page.txt'
)
);
```
### Helper
Useful methods to minify controller codebase
``` php
$helper = new \Yggverse\Gemini\Dokuwiki\Helper(
new \Yggverse\Gemini\Dokuwiki\Filesystem(),
new \Yggverse\Gemini\Dokuwiki\Reader()
);
```
#### Helper::getChildrenSectionLinksByUri
Return simple array of children section links in Gemini format
``` php
var_dump (
$helper->getChildrenSectionLinksByUri(
'hello:world'
)
);
```
#### Helper::getChildrenPageLinksByUri
Return simple array of children page links in Gemini format
``` php
var_dump (
$helper->getChildrenPageLinksByUri(
'hello:world'
)
);
```
#### Helper::getPageLinkByPath
Return page link (that contain document name) in Gemini format
``` php
var_dump (
$helper->getPageLinkByPath(
$filesystem->getPagePathByUri(
'hello:world'
)
)
);
```
