novelWriter is a Markdown-like text editor designed for writing novels assembled from many smaller
text documents. It uses a minimal formatting syntax inspired by Markdown, and adds a meta data
syntax for comments, synopsis, and cross-referencing between files. It's designed to be a simple
text editor that allows for easy organisation of text files and notes, built on plain text files
for robustness.

The plain text files are suitable for version control software, and also well suited for file
synchronisation tools. The core project structure is stored in a single project XML file. Other
meta data is primarily saved in JSON files.

The full documentation is available on [readthedocs.io](https://novelwriter.readthedocs.io).

## Implementation

The application is written in Python 3 using Qt5 via PyQt5. It is developed on Linux, but it should
in principle work fine on other operating systems as well, as long as dependencies are met. It is
regularly tested on Ubuntu Linux, Windows, and macOS.

## Project Contributions

Contributions to this project are welcome. However, please read the
[Contributing Guide](https://github.com/vkbo/novelWriter/blob/main/CONTRIBUTING.md) before
submitting larger additions or changes to this project.

## Key Features

Some key features of novelWriter are listed below. Consult the
[documentation](https://novelwriter.readthedocs.io) for more information.

### Markdown Flavour

novelWriter is _not_ a full-feature Markdown editor. It is a plain text editor that uses
Markdown-like syntax to allow for a minimal set of formatting that is useful for the specific task
of writing novels. The formatting is currently limited to:

* Headings levels 1 to 4 using the `#` syntax only.
* Emphasised and strongly emphasised text. These are rendered as italicised and bold text.
* Strikethrough text.
* Hard line breaks using two or more spaces at the end of a line.

That is it. Features not supported in the editor are also not exported when using the export tool.

In addition, novelWriter adds the following, which is otherwise not supported by Markdown:

* A line starting with `%` is treated as a comment and not rendered on exports unless requested.
  Comments do not count towards the word count.
* If the first word of the comment is `synopsis:`, the comment is indexed and treated as the
  synopsis for the section of text under the same header. These synopsis comments can be used to
  build an outline and exported to external documents.
* A set of meta data keyword/values starting with the character `@`. This is used for tagging
  and inter-linking documents, and can also be included when generate a project outline.
* A variety of thin and non-breaking spaces are supported. Some of them depend on the system
  running at least Qt 5.9. Earlier versions of Qt will unfortunately strip them out when saving.
* Tabs can be used in the text, and should be properly aligned in both editor and viewer. This can
  be used to make simple tables and lists. Full Markdown tables and lists are not supported. Note
  that for HTML exports, most browsers will treat a tab as a space, so it may not show up like
  expected. Open Document exports should produce the expected result.

The core export formats of novelWriter are Open Document and HTML5. Open Document is an open
standard for office type documents that is supported by most office applications. See
[Open Document > Application Support](https://en.wikipedia.org/wiki/OpenDocument#Application_support)
for more details.

You can also export the entire project as a single novelWriter Markdown-flavour document. These can
later be imported again into novelWriter. In addition, printing and export to PDF is offered
through the Qt library, although with limitations to formatting.

### Colour Themes

The editor has syntax highlighting for the features it supports, and includes a set of different
syntax highlighting themes. Optional GUI themes are also available, including dark themes.

### Easy Organising of Project Files

The structure of the project is shown on the left hand side of the main window. Project files are
organised into root folders, indicating what class of file they are. The most important root folder
is the `Novel` folder, which contains all of the files that make up the finished novel. Each root
folder can have subfolders. Subfolders have no impact on the final project structure, they are
there for you to organise your files in whatever way you want.

The editor supports four levels of headings, which determines what level the following text belongs
to. Headings of level one signify a book or partition title. Headings of level two signify the
start of a new chapter. Headings of level three signify the start of a new scene. Headings of level
four can be used internally in each scene to separate sections.

Each novel file can be assigned a layout format, which shows up as a flag next to the item in the
project tree. These are mostly to help the user track what they contain, but they also have some
impact on the format of the exported document. See the
[documentation](https://novelwriter.readthedocs.io) for further details.

### Project Notes

Supporting note files can be added for the story plot, characters, locations, story timeline, etc.
These have their separate root folders. These are optional files.

### Visualisation of Story Elements

The different notes can be assigned tags, which other files can refer back to using `@`-prefixed
meta keywords. This information can be used to display an outline of the story, showing where each
scene connects to the plot, and which characters, etc. occur in them. In addition, the tags
themselves are clickable in the document view pane, and control-clickable in the editor. They make
it possible to quickly navigate between the documents while editing.

## Standard Installation

For a regular installation, it is recommended that you download one of the minimal zip files from
the [Releases](https://github.com/vkbo/novelWriter/releases) page or the
[novelwriter.io](https://novelwriter.io/) website.
The [documentation](https://novelwriter.readthedocs.io/) has detailed install instructions for
[Linux](https://novelwriter.readthedocs.io/en/latest/setup_linux.html),
[Windows](https://novelwriter.readthedocs.io/en/latest/setup_windows.html), and
[macOS](https://novelwriter.readthedocs.io/en/latest/setup_mac.html).
They are pretty straightforward.

## Running from Source

If you want to run novelWriter directly from the source code, you must run the `novelWriter.py`
file from command line.

**Note:** You may need to replace `python` with `python3` and `pip` with `pip3` in the instructions
below on some systems. You may also want to add the `--user` flag for `pip` to install in your user
space only.

### Dependencies

Dependencies can generally be installed from PyPi with:
```bash
pip install pyqt5 lxml pyenchant
```

### Additional Steps for Linux

On Linux, you can most likely find the dependencies in your distribution's repository. On Ubuntu
and Debian, run:
```bash
sudo apt install python3-pyqt5 python3-lxml python3-enchant
```

If you want to set up a launcher on Linux, you can run:
```bash
python setup.py xdg-install
```

### Additional Steps for macOS

First, make sure you have properly set up Python3 with Homebrew. If not, check their
[documentation](https://docs.brew.sh/Homebrew-and-Python).
In addition, the following steps are necessary to install all dependencies:
```bash
brew install enchant
pip3 install --user -r requirements.txt
pip3 install --user pyobjc
```

### Additional Steps for Windows

Windows doesn't by default come with Python installed. If you haven't installed it already, get it
from [python.org/downloads](https://www.python.org/downloads/). Remember to select "Add Python to
PATH" during the installation.

The script `setup_windows.bat` can be used to create desktop and start menu icons for novelWriter.
The script will also install dependencies for you from PyPi.

## Internationalisation

If you install from source, you must build the translation files yourself if you want to switch to
a different GUI language than British English. This requires that you have the Qt translation
framework installed. Check the specific instruction in the README in the `i18n` source folder for
how to build the translation files.

## Debugging

If you need to debug novelWriter, you must run it from the command line. It takes a few parameters,
which can be listed with the switch `--help`. The `--info`, `--debug` or `--verbose` flags are
particularly useful for increasing logging output for debugging.
