TOPIC_INTRODUCTION = '''>Nomad Network
`c`*Communicate Freely.`*
`a
The intention with this program is to provide a tool to that allows you to build private and resilient communications platforms that are in complete control and ownership of the people that use them.
Nomad Network is build on LXMF and Reticulum, which together provides the cryptographic mesh functionality and peer-to-peer message routing that Nomad Network relies on. This foundation also makes it possible to use the program over a very wide variety of communication mediums, from packet radio to fiber.
Nomad Network does not need any connections to the public internet to work. In fact, it doesn't even need an IP or Ethernet network. You can use it entirely over packet radio, LoRa or even serial lines. But if you wish, you can bridge islanded Reticulum networks over the Internet or private ethernet networks, or you can build networks running completely over the Internet. The choice is yours.
The current version of the program should be considered a beta release. The program works well, but there will most probably be bugs and possibly sub-optimal performance in some scenarios. On the other hand, this is the best time to have an influence on the direction of the development of Nomad Network. To do so, join the discussion on the Nomad Network project on GitHub.
'''
TOPIC_CONCEPTS = '''>Concepts and Terminology
The following section will briefly introduce various concepts and terms used in the program.
>>Peer
A `*peer`* refers to another Nomad Network client, which will generally be operated by another person. But since Nomad Network is a general LXMF client, it could also be any other LXMF client, program, automated system or machine that can communicate over LXMF.
All peers (and nodes) are identified by their `*address`* (which is, technically speaking, a Reticulum destination hash). An address consist of 20 hexadecimal characters, and looks like this:
`c<b8ea8f92541c9a275f0e>
`l
Anyone can choose whatever display name they want, but addresses are always unique, and generated from the unique cryptographic keys of the peer. This is an important point to understand. Since there is not anyone controlling naming or address spaces in Nomad Network, you can easily come across another user with the same display name as you.
Your addresses will always be unique though, and you must always verify that the address you are communicating with is matching the address of the peer you expect to be in the other end.
To make this easier, Nomad Network allows you to mark peers and nodes as either `*trusted`*, `*unknown`* or `*untrusted`*. In this way, you can mark the peers and nodes that you know to be legitimate, and easily spot peers with similar names as unrelated.
>>Announces
An `*announce`* can be sent by any peer or node on the network, which will notify other peers of its existence, and contains the cryptographic keys that allows other peers to communicate with it.
In the `![ Network ]`! section of the program, you can monitor announces on the network, initiate conversations with announced peers, and announce your own peer on the network. You can also connect to nodes on the network and browse information shared by them.
>>Conversations
Nomad Network uses the term `*conversation`* to signify both direct peer-to-peer messaging threads, and also discussion threads with an arbitrary number of participants that might change over time.
Both things like discussion forums and chat threads can be encapsulated as conversations in Nomad Network. The user interface will indicate the different characteristics a conversation can take, and also what form of transport encryption was used for messages within.
In the `![ Conversations ]`! part of the program you can view and interact with all currently active conversations. You can also edit nickname and trust settings for peers belonging to these conversations here. To edit settings for a peer, select it in the conversation list, and press `!Ctrl-E`!.
By default, Nomad Network will attempt to deliver messages to a peer directly. This happens by first establishing an encrypted link directly to the peer, and then delivering the message over it.
If the desired peer is not available because it has disconnected from the network, this method will obviously fail. In this case, Nomad Network will attempt to deliver the message to a node, which will store and forward it over the network, for later retrieval by the destination peer. The message is encrypted with an ephemeral key before being transmitted to the network, and is only readable by the intended recipient.
For propagated delivery to work, one or more nodes must be available on the network. If one or more trusted nodes are available, Nomad Network will automatically select the most suitable node to send the message via, but you can also manually specify what node to use.
To select a node manually, go to the `![ Network ]`! part of the program, choose the desired node in the `*Known Nodes`* list, and select the `!< Info >`! button. In the `!Node Info`! dialog, you can specify the selected node as the default propagation node.
>>Node
A Nomad Network `*node`* is an instance of the Nomad Network program that has been configured to host information for other peers and help propagate messages and information on the network.
Nodes can host pages (similar to webpages) written in a markup-language called `*micron`*, as well as make files and other resources available for download for peers on the network. Nodes also form a distributed message store for offline users, and allows messages to be exchanged between peers that are not online at the same time.
If no nodes exist on a network, all peers will still be able to communicate directly peer-to-peer, but both endpoints of a conversation will need to be available at the same time to converse. When nodes exist on the network, messages will be held and syncronised between nodes for deferred delivery if the destination peer is unavailable. Nodes will automatically discover and peer with each other, and handle synchronisation of message stores.
To learn how to host your own node, read the `*Hosting a Node`* section of this guide.
'''
TOPIC_HOSTING = '''>Hosting a Node
To host a node on the network, you must enable it in the configuration file, by setting `*enable_node`* directive to `*yes`*. You should also configure the other node-related parameters such as the node name and announce interval settings. Once node hosting has been enabled in the configuration, Nomad Network will start hosting your node as soon as the program is lauched, and other peers on the network will be able to connect and interact with content on your node.
By default, no content is defined, apart from a short placeholder home page. To learn how to add your own content, read on.
>>Pages
Nomad Network nodes can host pages similar to web pages, that other peers can read and interact with. Pages are written in a compact markup language called `*micron`*. To learn how to write formatted pages with micron, see the `*Markup`* section of this guide (which is, itself, written in micron). Pages can be linked arbitrarily with hyperlinks, that can also link to pages (or other resources) on other nodes.
To add pages to your node, place micron files in the `*pages`* directory of your Nomad Network programs `*storage`* directory. By default, the path to this will be `!~/.nomadnetwork/storage/pages`!. You should probably create the file `!index.mu`! first, as this is the page that will get served by default to a connecting peer.
You can control how long a peer will cache your pages by including the cache header in a page. To do so, the first line of your page must start with `!#!c=X`!, where `!X`! is the cache time in seconds. To tell the peer to always load the page from your node, and never cache it, set the cache time to zero. You should only do this if there is a real need, for example if your page displays dynamic content that `*must`* be updated at every page view. The default caching time is 12 hours. In most cases, you should not need to include the cache control header in your pages.
You can use a preprocessor such as PHP, bash, Python (or whatever you prefer) to generate dynamic pages. To do so, just set executable permissions on the relevant page file, and be sure to include the interpreter at the beginning of the file, for example `!#!/usr/bin/python3`!.
>>Files
Like pages, you can place files you want to make available in the `!~/.nomadnetwork/storage/files`! directory. To let a peer download a file, you should create a link to it in one of your pages.
>>Links and URLs
Links to pages and resources in Nomad Network use a simple URL format. Here is an example:
`!1385edace36466a6b3dd:/page/index.mu`!
The first part is the 10 byte destination address of the node (represented as readable hexadecimal), followed by the `!:`! character. Everything after the `!:`! represents the request path.
By convention, Nomad Network nodes maps all hosted pages under the `!/page`! path, and all hosted files under the `!/file`! path. You can create as many subdirectories for pages and files as you please, and they will be automatically mapped to corresponding request paths.
You can omit the destination address of the node, if you are reffering to a local page or file. You must still keep the `!:`! character. In such a case, the URL to a page could look like this:
`!:/page/other_page.mu`!
The URL to a local file could look like this:
`!:/file/document.pdf`!
Links can be inserted into micron documents. See the `*Markup`* section of this guide for info on how to do so.

'''
TOPIC_FIRST_RUN = '''>First Time Information
Hi there. This first run message will only appear once. It contains a few pointers on getting started with Nomad Network, and getting the most out of the program.
You're currently located in the guide section of the program. I'm sorry I had to drag you here by force, but it will only happen this one time, I promise. If you ever get lost, return here and peruse the list of topics you see on the left. I will do my best to fill it with answers to mostly anything about Nomad Network.
To get the most out of Nomad Network, you will need a terminal that supports UTF-8 and at least 256 colors, ideally true-color. If your terminal supports true-color, you can go to the `![ Config ]`! menu item, launch the editor and change the configuration.
It is recommended to use a terminal size of at least 122x32. Nomad Network will work with smaller terminal sizes, but the interface might feel a bit cramped.
If you don't already have a Nerd Font installed (see https://www.nerdfonts.com/), I also highly recommend to do so, since it will greatly expand the amount of glyphs, icons and graphics that Nomad Network can use. Once you have your terminal set up with a Nerd Font, go to the `![ Config ]`! menu item and enable Nerd Fonts in the configuration instead of normal unicode glyphs.
Nomad Network expects that you are already connected to some form of Reticulum network. That could be as simple as the default UDP-based demo interface on your local ethernet network. This short guide won't go into any details on building networks, but you will find other entries in the guide that deal with network setup and configuration.
At least, if Nomad Network launches, it means that it is connected to a running Reticulum instance, that should in turn be connected to `*something`*, which should get you started.
For more some more information, you can also read the `*Introduction`* section of this guide.
Now go out there and explore. This is still early days. See what you can find and create.

'''
TOPIC_NETWORKS = '''>Network Configuration
Nomad Network uses the Reticulum Network Stack for communication and encryption. This means that it will use any interfaces and communications channels already defined in your Reticulum configuration.
Reticulum supports using many kinds of devices as networking interfaces, and allows you to mix and match them in any way you choose. The number of distinct network topologies you can create with Reticulum is more or less endless, but common to them all is that you will need to define one or more interfaces for Reticulum to use.
If you have not changed the default Reticulum configuration, which should be located at `!~/.reticulum/config`!, you will have one interface active right now. With it, you should be able to communicate with any other peers and nodes that exist on your local ethernet or WiFi network, if your system is connected to one, and most probably nothing else outside of that.
To learn how to configure your Reticulum setup to use LoRa radios, packet radio or other interfaces, or connect to other Reticulum networks via the Internet, the best places to start is to read the relevant parts of the Reticulum Manual, which can be found on GitHub:
`c`_https://markqvist.github.io/Reticulum/manual/interfaces.html`_
`l
If you don't currently have access to the Internet, the default Reticulum configuration file is also full of examples of all the supported interface types, and it should be relatively simple to get a working setup going just from those examples.
For future reference, you can download the Reticulum Manual in PDF format here:
`c`_https://github.com/markqvist/Reticulum/raw/master/docs/Reticulum%20Manual.pdf`_
`l
It might be nice to keep that handy when you are not connected to the Internet, as it is full of information and examples that are also very relevant to Nomad Network.
>The Unsigned.io Testnet
If you have Internet access, and just want to get started experimenting, you are welcome to join the Unsigned.io RNS Testnet. The testnet is just that, an informal network for testing and experimenting. It will be up most of the time, and anyone can join, but it also means that there's no guarantees for service availability.
The Testnet also runs the latest version of Reticulum, often even a short while before it is publicly released, which means strange behaviour might occur. If none of that scares you, add the following interface to your Reticulum configuration file to join:
>>
[[RNS Testnet Frankfurt]]
type = TCPClientInterface
interface_enabled = yes
outgoing = True
target_host = frankfurt.rns.unsigned.io
target_port = 4965

TOPIC_MARKUP = '''>Outputting Formatted Text
>>>>>>>>>>>>>>>
-\u223f
<
`c`!Hello!`! This is output from `*micron`*
Micron generates formatted text for your terminal
`a
>>>>>>>>>>>>>>>
-\u223f
<
Nomad Network supports a simple and functional markup language called `*micron`*. If you are familiar with `*markdown`* or `*HTML`*, you will feel right at home writing pages with micron.
With micron you can easily create structured documents and pages with formatting, colors, glyphs and icons, ideal for display in terminals.
>>Recommendations and Requirements
While micron can output formatted text to even the most basic terminal, there's a few capabilities your terminal `*must`* support to display micron output correctly, and some that, while not strictly necessary, make the experience a lot better.
Formatting such as `_underline`_, `!bold`! or `*italics`* will be displayed if your terminal supports it.
If you are having trouble getting micron output to display correctly, try using `*gnome-terminal`*, which should work with all formatting options out of the box. Most other terminals will work fine as well, but you might have to change some settings to get certain formatting to display correctly.
>>>Encoding
All micron sources are intepreted as UTF-8, and micron assumes it can output UTF-8 characters to the terminal. If your terminal does not support UTF-8, output will be faulty.
>>>Colors
Shading and coloring text and backgrounds is integral to micron output, and while micron will attempt to gracefully degrade output even to 1-bit terminals, you will get the best output with terminals supporting at least 256 colors. True-color support is recommended.
>>>Terminal Font
While any unicode capable font can be used with micron, it's highly recommended to use a `*"Nerd Font"`* (see https://www.nerdfonts.com/), which will add a lot of extra glyphs and icons to your output.
> A Few Demo Outputs
`F222`Bddd

`b
If you want to make a break, horizontal dividers can be inserted. They can be plain, like the one below this text, or you can style them with unicode characters and glyphs, like the wavy divider in the beginning of this document.
-
`cText can be `_underlined`_, `!bold`! or `*italic`*.
You can also `_`*`!`B5d5`F222combine`f`b`_ `_`Ff00f`Ff80o`Ffd0r`F9f0m`F0f2a`F0fdt`F07ft`F43fi`F70fn`Fe0fg`` for some fabulous effects.
`a
>>>Sections and Headings
You can define an arbitrary number of sections and sub sections, each with their own named headings. Text inside sections will be automatically indented.
-
If you place a divider inside a section, it will adhere to the section indents.
>>>>>
If no heading text is defined, the section will appear as a sub-section without a header. This can be useful for creating indented blocks of text, like this one.
>Micron tags
Tags are used to format text with micron. Some tags can appear anywhere in text, and some must appear at the beginning of a line. If you need to write text that contains a sequence that would be interpreted as a tag, you can escape it with the character \\.
In the following sections, the different tags will be introduced. Any styling set within micron can be reset to the default style by using the special \\`\\` tag anywhere in the markup, which will immediately remove any formatting previously specified.
>>Alignment
To control text alignment use the tag \\`c to center text, \\`l to left-align, \\`r to right-align, and \\`a to return to the default alignment of the document. Alignment tags must appear at the beginning of a line. Here is an example:
`Faaa
`=
`cThis line will be centered.
So will this.
`aThe alignment has now been returned to default.
`rThis will be aligned to the right
``
`=
``
The above markup produces the following output:
`Faaa`B333
`cThis line will be centered.
So will this.
`aThe alignment has now been returned to default.
`rThis will be aligned to the right
``
>>Formatting
Text can be formatted as `!bold`! by using the \\`! tag, `_underline`_ by using the \\`_ tag and `*italic`* by using the \\`* tag.
Here's an example of formatting text:
`Faaa
`=
We shall soon see `!bold`! paragraphs of text decorated with `_underlines`_ and `*italics`*. Some even dare `!`*`_combine`` them!
`=
``
The above markup produces the following output:
`Faaa`B333
We shall soon see `!bold`! paragraphs of text decorated with `_underlines`_ and `*italics`*. Some even dare `!`*`_combine`!`*`_ them!
``
>>Sections
To create sections and subsections, use the > tag. This tag must be placed at the beginning of a line. To specify a sub-section of any level, use any number of > tags. If text is placed after a > tag, it will be used as a heading.
Here is an example of sections:
`Faaa
`=
>High Level Stuff
This is a section. It contains this text.
>>Another Level
This is a sub section.
>>>Going deeper
A sub sub section. We could continue, but you get the point.
>>>>
Wait! It's worth noting that we can also create sections without headings. They look like this.
`=
``
The above markup produces the following output:
`Faaa`B333
>High Level Stuff
This is a section. It contains this text.
>>Another Level
This is a sub section.
>>>Going deeper
A sub sub section. We could continue, but you get the point.
>>>>
Wait! It's worth noting that we can also create sections without headings. They look like this.
``
>Colors
Foreground colors can be specified with the \\`F tag, followed by three hexadecimal characters. To return to the default foreground color, use the \\`f tag. Background color is specified in the same way, but by using the \\`B and \\`b tags.
Here's a few examples:
`Faaa
`=
You can use `B5d5`F222 color `f`b `Ff00f`Ff80o`Ffd0r`F9f0m`F0f2a`F0fdt`F07ft`F43fi`F70fn`Fe0fg`f for some fabulous effects.
`=
``
The above markup produces the following output:
`Faaa`B333
You can use `B5d5`F222 color `f`B333 `Ff00f`Ff80o`Ffd0r`F9f0m`F0f2a`F0fdt`F07ft`F43fi`F70fn`Fe0fg`f for some fabulous effects.
``
>Links
Links to pages, files or other resources can be created with the \\`[ tag, which should always be terminated with a closing ]. You can create links with and without labels, it is up to you to control the formatting of links with other tags. Although not strictly necessary, it is good practice to at least format links with underlining.
Here's a few examples:
`Faaa
`=
Here is a link without any label: `[1385edace36466a6b3dd:/page/index.mu]
This is a `[labeled link`1385edace36466a6b3dd:/page/index.mu] to the same page, but it's hard to see if you don't know it
Here is `F00a`_`[a more visible link`1385edace36466a6b3dd:/page/index.mu]`_`f
`=
``
The above markup produces the following output:
`Faaa`B333
Here is a link without any label: `[1385edace36466a6b3dd:/page/index.mu]
This is a `[labeled link`1385edace36466a6b3dd:/page/index.mu] to the same page, but it's hard to see if you don't know it
