comNG Introduction

Introduction

comNGLang is a simple language defined by comNG, the purpose is to highlight log text without extra decorator chars. Thanks to monaco editor, it make this possible.

Syntax

We defined 10 tokens in comNGLang, each token has a regex to match certain character pattern and render this pattern with certain color. In following section, we will give out regex and description for each token.

Regex

Have a look at these regex, it’s the most precise description of comNGLang syntax definition.

Fatal

Start with [fatal](case ignore, [] optional, end with at least 1 space) or [F](case sensitive, [] optional, end with at least 1 space), the whole line will be rendered as fatal line.

Single [fatal](case ignore, [] optional, start/end with at least 1 space) or [F](case sensitive, [] optional, start/end with at least 1 space), the word will be rendered as fatal word.
