# Markor
Text editor - Notes & ToDo (for Android).
Simple and lightweight, supporting Markdown, todo.txt, Zim & more!
**Download:** [F-Droid](https://f-droid.org/repository/browse/?fdid=net.gsantner.markor), [GitHub](https://github.com/gsantner/markor/releases/latest)
Markor is a TextEditor for Android.
This project aims to make an editor that is versatile, flexible, and lightweight.
Markor utilizes simple markup formats like Markdown and todo.txt for note-taking and list management.
It is versatile at working with text; it can also be used for keeping bookmarks, copying to clipboard, fast opening a link from text and lots more.
Created files are interoperable with any other plaintext software on any platform.
Markor is openly developed free software that accepts community contributions.

## New features in the latest update - Markor v2.11 - AsciiDoc, CSV and Org-Mode, Todo.txt advanced search, Line numbers
### Line number support
Markor supports showing line numbers now. In the top file menu you can find a new option to enable numbers.
It is supported in editor as well in view mode of documents (in code blocks).
### New format: AsciiDoc
AsciiDoc is one of the new formats that are now supported.
While it might be not as much fleshed out like Markdown, it should fit for general use.
### New format: CSV
[CSV file](https://en.wikipedia.org/wiki/Comma-separated_values) are supported now (in sense of syntax highlighting and preview).
For details see [CSV README](doc/2023-06-02-csv-readme.md), it was implemented in #1988, #1987, #1980, #1667.
* Editor with SyntaxHighlighter
* Each csv column is shown in a different unique color to see which csv-data belongs to which colum/header
* Preview as html-Table with export as pdf
* A csv column may contain markdown (See Example column in screenshot)
### New format: Org-Mode
The third and last new format newly added is Org-Mode. Note that currently only editor syntax highlighting and action buttons to make editing easier are available.
There is no dedicated view mode implemented.

# FAQ
## File browser & file management
#### How do I save a file?
Markor automatically saves text when you leave Markor or close a file. Additionally there is save button in the top menu.
#### How do I save files to SD Cards?
Browse to the start folder of your SD Card and press the + button (using file browser or the menu option). Now press the plus button and follow the steps in the dialog. Afterwards Markor's file browser won't strike out filenames anymore and files are writable.
#### How to synchronize files?
Markor is and will stay an offline focused application. It works with sync synchronization apps, they have to do syncing respectively.
Sync clients known to work in combination include BitTorrent Sync, Dropbox, FolderSync, OwnCloud, NextCloud, Seafile, Syncthing, Syncopoli and others.
The project recommendation is Syncthing. [-> Guide for Syncthing](doc/2020-04-04-syncthing-file-sync-setup-how-to-use-with-markor.md)
#### What is Notebook?
The root folder of your files! Markor starts with this folder at the main screen and allows you to browse files. You can work at any (accessible) file & location with Markor.
#### What is ToDo?
Your main to-do list file in todo.txt format. You can access it by swiping once at the main screen, by selecting todo.txt at Notebook, or by using the dedicated launcher. You can also open it from Notebook or other apps! You will also have the option to create a to-do task when sharing text into Markor when the text is just one line. The location of this file is freely choosable and independent from the Notebook directory.
#### What is QuickNote?
The fastest and easiest way to take notes! QuickNote is a file in Markdown format with a freely choosable file location. You can access it by swiping twice at the main screen, by selecting QuickNote at Notebook, or by using the dedicated launcher. The location of this file is freely choosable and independent from the Notebook directory.
#### Launchers
A launcher is a "start menu option" in your devices launcher (=appdrawer / start menu). When Markor is installed you have the start menu option for Markor. When the Markor settings option "Launcher (Special Documents)" is enabled, you get the additional start menu options for ToDo and QuickNote. Note that a device restart is required when you change this option.
## Format: Markdown
#### What is Markdown?
A general purpose markup format for documents of all kinds. As Markdown gets converted to HTML prior displaying a rendered view, you can also include HTML in the text, thus you can do everything web browsers can do.
CommonMark is the specification that the markdown parser used in Markor implements.

#### Links to files that contains spaces
Most Markdown applications use URL encoding for links, so does Markor. This means replace every space` ` with `%20`. This ensures that your Markdown content is compatible with most other Markdown applications.
Markor has a dedicated button for adding links and file references, which automatically applies this appropiate format. Take a look at this [video](https://user-images.githubusercontent.com/6735650/63089879-e6aa9400-bf48-11e9-87c1-78a1ba1c444f.gif) to find out where the file reference button is located and how to use it.
Example: `[alt](my cool file.md)` ⮕ `[alt](my%20cool%20file.md)`.
#### Can I use Markor in class to write down equations? (Math)
Yes, Markor has advanced functionalities for math! Enable the feature by checking Settings»Format»Markdown»Math.
Markor's [markdown-reference.md](samples/markor-markdown-reference.md) template (available from new file dialog) showcases some examples.
