# Simple Text Viewer
Desktop application for browse source code with syntax highlighting on Linux OS, written on C++ Qt 5.x
### Motivation
Browsing with application source code in GUI mode on OS Linux with syntax highlighting in read-only mode opening files, as a replacement of viewer in Double Commander.
## Base functions
1. Opening files only in read-only mode
2. Syntax highlighting of source code
3. Custom color theme of syntax highlighting
4. Custom create rules of syntax highlighting based on types of file
5. Searching text in sources
## Files configurations and paths
Base resource files locate in ***/usr/share/simpletextviewer***
- Color themes ***../themes***. For example: ***default.theme***
- Rules of syntax highlighting ***../syntax***, For example: ***syntax_cpp.syn***
> File name of syntax contain with **syntax_xxx.syn**
>
> **where**
>
> xxx - extention of opened file for browse
Base application config file location in
$HOME/.config/simpletextviewer/.editor.conf
This file contain current used theme name:
theme=default
## Creating color theme
File of color theme contains color with KEY=COLOR
```
background=#FFFFFF
base_text_color=#000000
keywords=#000C80
braces=#FFAC23
comments=#858585
objects=#000000
control_characters=#000000
macros=#000000
strings=#115C00
chars=#115C00
numbers=#FF0000
line_number=#000000
current_line=#C7C7C7
preprocessor=#0C6F5A
```
> Key names and color format must be strict keeps.
## Creating rules of syntax highlighting
File of syntax rules contains lines with KEY=VALUE
Where
KEY - name of type word or characters
VALUE = space-separated word which must coloring
For example:
```
keywords=int bool char byte long double
comments_single=//
comments_block=/* */
preprocessor=#include #ifndef #define #endif
objects=Array List Set QString QFile QColor
macros=SIGNAL tr
braces=[ ] { } ( )
control_characters=|| && :: << >> -> => <= != == & ! ? = . , + - = | ; < > *
```
For values such as "braces", "control_characters" importance is order: in begin placed complex values, further - simple values.
## In planning
- Settings dialog for create color themes and syntax rules
