# Themes and Styles
|
|
## Themes
|
|
A **theme** specifies the look of VNote, the style of the editor and read mode, and the syntax highlight style of code block.
|
|
|
|
A theme corresponds to a folder in the `themes` subfolder in the configuration folder with structure:
|
|
|
|
```
|
|
themes/
|
|
├── v_pure
|
|

```
|
|
|
|
- `v_pure.palette`: the main entry of a theme, which specifies other files and styles;
|
|
- `v_pure.qss`: file for [**Qt Style Sheet**](http://doc.qt.io/qt-5/stylesheet-reference.html), which specifies the look of all the widgets;
|
|
- `v_pure.mdhl`: file for the style of Markdown editor, using [The Syntax of PEG Markdown Highlight Stylesheets](http://hasseg.org/peg-markdown-highlight/docs/stylesheet_syntax.html);
|
|
- `v_pure.css`: file for the style of read mode;
|
|
- `v_pure_codeblock.css`: file for the style of the code block highlight in read mode, using [Highlight.js](https://highlightjs.org/static/demo/);
|
|
|
|
### Palette of Theme
|
|
Let's look into the `.palette` file. The file is in `INI` format.
|
|
|
|
#### [metadata]
|
|
This section specifies other style files this theme will use.
|
|
|
|
```ini
|
|
; File path could be absolute path or relative path (related to this file).
|
|
; Use @color_tag to reference a style.
|
|
|
|
[metadata]
|
|
qss_file=v_pure.qss
|
|
mdhl_file=v_pure.mdhl
|
|
css_file=v_pure.css
|
|
codeblock_css_file=v_pure_codeblock.css
|
|
version=2
|
|
```
|
|
|
|
#### [phony]
|
|
This section is used to define **variables** for fundamental, abstract color attributes. A variable could be referenced by `@variable_name` to define another variable.
|
|
|
|
These variables are referenced by other sections, so you are free to choose and define your own ones.
|
|
|
|
```ini

#### [soft_defined]

|
|
|
|
```ini

#### [widgets]

|
|
|

The `qss` file may look like this if you are curious:
|
|
|
|
```css
|
|
/* QWidget */
|
|
QWidget
|
|
{
|
|
color: @widget_fg;
|
|
font-family: "Hiragino Sans GB", "冬青黑体", "Microsoft YaHei", "微软雅黑", "Microsoft YaHei UI", "WenQuanYi Micro Hei", "文泉驿雅黑", "Dengxian", "等线体", "STXihei", "华文细黑", "Liberation Sans", "Droid Sans", "NSimSun", "新宋体", "SimSun", "宋体", "Helvetica", "sans-serif", "Tahoma", "Arial", "Verdana", "Geneva", "Georgia", "Times New Roman";
|
|
}
|
|
|
|
QWidget[NotebookPanel="true"] {
|
|
padding-left: 3px;
|
|
}
|
|
/* End QWidget */
|
|
|
|
/* QMainWindow */
|
|
QMainWindow {
|
|
color: @base_fg;
|
|
background: @base_bg;
|
|
}
|
|
|
|
QMainWindow::separator {
|
|
background: @dock_separator_bg;
|
|
width: 2px;
|
|
height: 2px;
|
|
}
|
|
|
|
QMainWindow::separator:hover {
|
|
background: @dock_separator_hover_bg;
|
|
}
|
|
/* End QMainWindow */
|
|
|
|
QMenuBar {
|
|
border: none;
|
|
background: @menubar_bg;
|
|
color: @menubar_fg;
|
|
}
|
|
|
|
QMenuBar::item:selected {
|
|
background: @menubar_item_selected_bg;
|
|
}
|
|
```
|
|
|
|
### Custom Themes
|
|
VNote supports custom themes. Just place your theme (folder) to the `themes` folder, restart VNote and choose your theme in the `File` menu.
|
|
|
|
The best way to custom a theme is tuning a defaut theme. VNote will output default themes in the `themes` folder (or if not, you could download it [here](https://github.com/tamlok/vnote/tree/master/src/resources/themes)). Copy a default theme and rename the `palette` file. Then you could tune it to your taste. Restart of VNote is needed to let the changes take effect.
|
|
|
|
## Editor Styles
|
|
Editor style is specified by a `mdhl` file. Each theme may carry a `mdhl` file. You could also apply another `mdhl` file instead of using the default one specified by the theme. Separate style file could be placed in the `styles` folder in the configuration folder. Restart of VNote is needed to scan new `mdhl` files and re-open of notes is needed to apply new style.
|
|
|
|
|
|
|
|
### Syntax of MDHL File
|
|
The `mdhl` file adopts the [The Syntax of PEG Markdown Highlight Stylesheets](http://hasseg.org/peg-markdown-highlight/docs/stylesheet_syntax.html) and expands it to support more elements.
|
|
|
|
```
|
|
# This is the default markdown styles used for Peg-Markdown-Highlight
|
|
# created by Le Tan(tamlokveer@gmail.com).
|
|
# For a complete description of the syntax, please refer to the original
|
|
# documentation of the style parser
|
|
# [The Syntax of PEG Markdown Highlight Stylesheets](http://hasseg.org/peg-markdown-highlight/docs/stylesheet_syntax.html).
|
|
# VNote adds some styles in the syntax which will be marked [VNote] in the comment.
|
|
#
|
|
# Note: Empty lines within a section is NOT allowed.
|
|
# Note: Do NOT modify this file directly. Copy it and tune your own style!

|
|
|
|
The syntax highlight of the code blocks in edit mode is specified by the `VERBATIM` element.
|
|
|
|
For example, if you want to change the font size of the code block in edit mode, you may need to add the following line under `VERBATIM` element:
|
|
|
|
```
|
|
font-size: -2
|
|
```
|
|
|
|
## Rendering Styles
|
|
Rendering style in read mode is specified by a `css` file. Each theme may carry a `css` file. You could also apply another `css` file instead of using the default one specified by the theme. Separate style file could be placed in the `styles` folder in the configuration folder. Restart of VNote is needed to scan new `css` files and re-open of notes is needed to apply new style.
|
|
|
|
|
|
|
|
## Code Block Rendering Styles
|
|
Rendering style in read mode is specified by a `css` file. Each theme may carry a `css` file. You could also apply another `css` file instead of using the default one specified by the theme. Separate style file could be placed in the `styles/codeblock_styles` folder in the configuration folder. Restart of VNote is needed to scan new `css` files and re-open of notes is needed to apply new style.
|
|
|
|
This file is used by the **highlight.js** renderer engine. You could download existing style files from [Highlight.js Github](https://github.com/isagalaev/highlight.js/tree/master/src/styles). |
