gemini-php

PHP 8 Library for Gemini Protocol

Usage

composer require yggverse/gemini:dev-main

DokuWiki

Toolkit provides DokuWiki API for Gemini.

Allows to simple deploy new apps or make existing website mirror

Examples

• β-Doku - DokuWiki Satellite for Gemini Protocol

Reader

Read DokuWiki and convert to Gemini

$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)

echo $reader->setRule(
    '/subject/ui',
    'replacement'
);

Reader::getMacroses

Reader::setMacroses

Reader::getMacros

Reader::setMacros

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!

echo $reader->toGemini(
    file_get_contents(
        '/host/data/pages/index.txt'
    )
);

Reader::getH1

Get document title

$gemini = $reader->toGemini(
    file_get_contents(
        '/host/data/pages/index.txt'
    )
);

echo $reader->getH1(
    $gemini
);

Reader::getLinks

Get document links

$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

$filesystem = new \Yggverse\Gemini\Dokuwiki\Filesystem(
    '/host/data' // storage location
);

Filesystem::getList

Return simple array of all files in storage

var_dump (
    $filesystem->getList(
        'hello:world'
    )
);

Filesystem::getTree

Return all files under the storage folder in tree format

var_dump (
    $filesystem->getTree(
        'hello:world'
    )
);

Filesystem::getPagePathsByPath

Return pages under the given data directory

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

var_dump (
    $filesystem->getPagePathByUri(
        'hello:world'
    )
);

Filesystem::getDirectoryUriByPath

Filesystem::getPageUriByPath

Return page URI in dokuwiki:format

var_dump (
    $filesystem->getPageUriByPath(
        '/full/path/to/page.txt'
    )
);

Filesystem::getMediaPathByUri

Return absolute path to stored media file

var_dump (
    $filesystem->getMediaPathByUri(
        'hello:world'
    )
);

Filesystem::getMimeByPath

Return file MIME if path match storage item

var_dump (
    $filesystem->getMimeByPath(
        '/full/path/to/page.txt'
    )
);

Filesystem::getDataByPath

Return file content if path match storage item

var_dump (
    $filesystem->getDataByPath(
        '/full/path/to/page.txt'
    )
);

Filesystem::isPath

Check path exist and match storage item

var_dump (
    $filesystem->isPath(
        '/full/path/to/page.txt'
    )
);

Helper

Useful methods to minify controller codebase

$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

var_dump (
    $helper->getChildrenSectionLinksByUri(
        'hello:world'
    )
);

Helper::getChildrenPageLinksByUri

Return simple array of children page links in Gemini format

var_dump (
    $helper->getChildrenPageLinksByUri(
        'hello:world'
    )
);

Helper::getPageLinkByPath

Return page link (that contain document name) in Gemini format

var_dump (
    $helper->getPageLinkByPath(
        $filesystem->getPagePathByUri(
            'hello:world'
        )
    )
);
