Log File Highlighter

![alt text][sample]

Description

A Visual Studio Code extension for adding color highlighting to log files. It is based on standard conventions for log4net log files but it's general enough to be useful for other variations of log files as well. The colors are customizable but by default the current color theme's colors are used.

Open Source

This extension is open source under the MIT License and completely free but if you like it and want to encourage further development, then you might want to consider supporting it using one of the links below:

But that's completely optional, of course 😊

Note

An earlier version of the syntax highlighting definition from this extension was included into Visual Studio Code version 1.20. If the default behavior of log files in VS Code is good enough for you, then you don't need this extension. However, if you want additional highlighting, customizable patterns and time duration calculation and visualization, then keep reading :-)

Features

Syntax Highlighting

The extension associates with .log files and applies coloring to the different elements in the file, for example:

Category	Example
Dates and times in ISO format, such as	2015-12-09, 2015-12-09 09:29, 2015-12-09 09:29:02.258
Dates and times in some culture-specific formats	12/09/2016, 12.09.2016, 12-09-2016, 12-09-2015 09:29, 12-09-2015 09:29:02,258

Visualization of Time Duration and Progress

If you select multiple lines of a .log file, some simple timestamp analysis is performed.

• A status bar item is displayed that indicates how many days, hours, minutes, seconds and milliseconds that is selected.
• A progress bar is also drawn under the timestamps in the selection to give a visual representation of each line's point in time within the selection.
• Press <kbd>Escape</kbd> to clear the progress bars.

Settings

• enableProgressIndicator can be used to disable the progress indicator feature. The default value is true. Set it to false to disable the feature.

• progressIndicatorUnderlineColor can be used to set the color of the progress indicator. The default value is #00ff1f8f. Note the alpha channel value at the end of the color value (8f). This can be used to make the color semi-transparent for mixing with the background color.

Example:

"logFileHighlighter.enableProgressIndicator": true,
"logFileHighlighter.progressIndicatorUnderlineColor": "#ffee00",

Tail Mode

The extension also supports a tail mode where the end of the log file is kept in view as new lines are added. To activate it, scroll to the end of the log file until a message is shown in the status bar: Log File Tail Mode

To deactivate tail mode for the current file, scroll up again.

This feature can be disabled by setting the logFileHighlighter.enableTailMode setting to false.
