Pepperminty Wiki

A Wiki in a box

Pepperminty Wiki is a complete wiki contained in a single file, inspired by @am2064's Minty Wiki. It's open source too (under MPL-2.0), so contributions are welcome!

Getting Started

Requirements

• PHP-enabled webserver
• PHP session support (for logging in, see here for more information)
• The following PHP extensions: mbstring, imagick (for preview generation), fileinfo (for proper mime type checking of uploaded files), and zip (for compress exports)
• Write access to own folder (only for editing)

Getting your own copy

Setting up your own copy of Pepperminty Wiki is easy. Since Pepperminty Wiki works on a module based system, all you need to do is choose the modules you want installed, and then configure your new installation so that it fits your needs. There are several ways to do this:

Method 1: Using the latest pre-built stable release

If you want a pre-built stable version, then you can use the latest release. It has a changelog that tells you what has changed since the last release, along with a pre-built version with all the latest modules.

Method 2: Grabbing the pre-built verion from the repository

If you're feeling lazy, you can grab the bleeding-edge version from this respository, which comes with all the latest modules. You can get it here.

Method 3: Using the online downloader

Pepperminty Wiki has a downloader that you can use to select the modules you want to include in your install. The online downloader will give you the latest stable release. You can find it here.

Method 3.5: Using the downloader offline

You can also you the downloader offline. Simply clone this repository to your web server and then point your web browser at your.server/path/to/perppminty/wiki/download.php.

Method 4: Building your own from source

Pepperminty Wiki can also be built from source (and I do this all the time when testing). Start by cloning the repository. Then go into the modules folder and append .disabled to the names of any modules you don't want to be included (e.g. modules/page-edit.php would become modules/page-edit.php.disabled). Then follow the instructions for your platform:

Windows

Simply run the build.bat script in the root of the repository. It will handle everything for you.

Linux and Everyone Else

Run the following commands from the root of the repository in order, adjusting them for your specific platform (these are for a standard Ubuntu Server install):

rm build/index.php
php rebuild_module_index.php
php build.php

These commands are also in build.sh. You can run that if you want. Here's an explanation of what each command does:

1. Deletes the old index.php in the build folder that comes with the repository
2. Rebuilds the module index that the build scripts uses to determine what modules it should include when building
3. Actually builds Pepperminty Wiki. Outputs to index.php.

Configuring

To configure your new install, open index.php in your favourite text editor and take a look at the comments. They should be self explanatory, but if you need any help, just contact me or open an issue.

Below are all the configuration directives that Pepperminty Wiki (and all the modules included in the repository) understand.

Key	Value	Explanation
sitename	string	The site's name. Used all over the place. Note that by default the session cookie is prefixed with a variant of the sitename, so changing this will log everyone out!
logo_url	url	A url that points to the site's logo. Leave blank to disable. When enabled, the logo will be inserted next to the site name on every page.
logo_postition	left	right
updateurl	url	The url from which to fetch updates. Defaults to the master (development) branch. If there is sufficient demand, a separate stable branch will be created. Note that if you use the automatic updater currently it won't save your module choices. MAKE SURE THAT THIS POINTS TO A HTTPS URL, OTHERWISE SOMEONE COULD INJECT A VIRUS INTO YOUR WIKI!
sitesecret	string	The secret key used to perform 'dangerous' actions, like updating the wiki. It is strongly advised that you change this!
editing	boolean	Determines whether editing is enabled. Set to false to disable disting for all users (anonymous or otherwise).
maxpagesize	integer	The maximum number of characters allowed on a single page. The default is 135,000 characters, which is about 50 pages.
clean_raw_html	boolean	Whether page sources should be cleaned of HTML before rendering. If set to true any raw HTML will be escaped before rendering. Note that this shouldn't affect code blocks - they should alwys be escaped. It is STRONGLY recommended that you keep this option turned on, ESPECIALLY if you allow anonymous edits as no sanitizing whatsoever is performed on the HTML. If you need a feature that the markdown parser doesn't have, please open an issue. Also note that some parsers may override this setting and escape HTML sequences anyway.
enable_math_rendering	boolean	Whether to enable client side mathematical expression parsing. When enabled LaTeX mathematical expressions can be enclosed in dollar signs like so: $x^2$. Turn off if you don't use it.
anonedits	boolean	Determines whether users who aren't logged in are allowed to edit your wiki. Set to true to allow anonymous users to edit the wiki.
defaultpage	string	The name of the page that will act as the home page for the wiki. This page will be served if the user didn't specify a page.
defaultaction	action name	The default action. This action will be performed if no other action is specified. It is recommended you set this to "view" - that way the user automatically views the default page (see above).
parser	parser name	The parser to use when rendering pages. Defaults to 'default', which is a modified version of slimdown, originally written by Johnny Broadway.
show_subpages	boolean	Whether to show a list of subpages at the bottom of the page.
subpages_display_depth	number	The depth to which we should display when listing subpages at the bottom of the page.
max_recent_changes	number	The maximum number of recent changes to display on the recent changes page.
optimize_pages	boolean	Whether to optimise all webpages generated. Currently this option only minifies inline css.
users	array of users	An array of usernames and passwords - passwords should be hashed with sha256. Put one user / password on each line, remembering the comma at the end. The last user in the list doesn't need a comma after their details though. Tip: use the hash action to hash passwords appropriately for Pepperminty Wiki, but remember to use an incognito window!
require_login_view	boolean	Whether to require that users login before they do anything else. If you combine this setting with the data_storage_dir option to move the storage directory outside your web root, this will completely hide your wiki from anyone who isn't logged in.
data_storage_dir	path	The directory in which to store all files, except this main index.php. A single dot ('.') denotes the current directory. Remember to omit the trailing slash from the directory name, as it is added automatically by Pepperminty Wiki. Combine with require_login_view in order to completely hide your wiki from anonymous users.
use_sha3	boolean	Whether to use the new sha3 hashing algorithm that was standardised on the 8th August 2015. Only works if you have strawbrary's sha3 extension installed. Get it here: https://github.com/strawbrary/php-sha3 Note: If you change this settings, make sure to update the password hashes above! Note that the hash action is aware of this option and will hash passwords appropriately based on this setting.
admins	array of usernames	An array of usernames that are administrators. Administrators can delete and move pages.
admindisplaychar	string	The string that is prepended before an admin's name on the nav bar. Defaults to a diamond shape (◆).
protectedpagechar	string	The string that is prepended a page's name in the page title if it is protected. Defaults to a lock symbol. (🔒)
admindetails	associative array	Contact details for the site administrator. Since users can only be added by editing this file, people will need a contact address to use to ask for an account. Displayed at the bottom of the page, and will be appropriately obfusticated to deter spammers.
export_allow_only_admins	boolean	Whether to only allow adminstrators to export the your wiki as a zip using the page-export module.
nav_links	array	An array of links and display text to display at the top of the site. See the comment in the settings file for more details.
nav_links_extra	array	An array of additional links in the above format that will be shown under "More" subsection, in the same format as the above.
nav_links_bottom	array	An array of links in the above format that will be shown at the bottom of the page, the same format as the above 2.
footer_message	string( + HTML)	A message that will appear at the bottom of every page. May contain HTML.
editing_message	string( + HTML)	A message that will appear just before the submit button on the editing page. May contain HTML.
upload_enabled	boolean	Whether to allow image uploads to the server.
upload_allowed_file_types	array of strings	An array of mime types that are allowed to be uploaded. Note that Pepperminty Wiki only does minimal checking of the actual content that is being uploaded - so please don't add any dangerous file types here on a parmanant bases for your own safety!
preview_file_type	mime type	The default file type for previews. Defaults to image/png. Also supports image/jpeg and image/webp. image/webp is a new image format that reduces image sizez by ~20%, but PHP still has some issues with invalid webp images.
default_preview_size	number	The default size of preview images.
mime_extension_mappings_location	path	The location of a file that maps mime types onto file extensions and vice versa. Used to generate the file extension for an uploaded file. Set to the default location of the mime.types file on Linux. If you aren't using linux, download this pastebin and point this setting at it instead.
mime_mappings_overrides	array of strings	An array of override mime mappings to translate mime types into the appropriate file extension. Use if the file pointed to by the above assigns weird file extensions to any file types.
min_preview_size	number	The minimum allowed size for generated preview images in pixels.
max_preview_size	number	The maximum allowed size for generated preview images in pixels.
search_characters_context	number	The number of characters that should be displayed either side of a matching term in the context below each search result.
search_title_matches_weighting	number	The weighting to give to search term matches found in a page's title.
search_tags_matches_weighting	number	The weighting to give to search term matches found in a page's tags.
css	string of css	A string of css to include. Will be included in every page. This may also be a url that references an external stylesheet.
favicon	url	A url that points to the favicon for your wiki.
session_prefix	string	The prefix that should be used in the names of the session variables. Defaults to an all lower case version of the site name with all non alphanumeric characters removed. Remember that changing this will log everyone out since the session variable's name will have changed. Normally you won't have to change this - This setting is left over from when we used a cookie to store login details. By default this is set to a safe variant of your site name.
