This plugin for Sublime Text 3 will color-highlight log files from 128 Technology routers.
Before:
After:
This plugin is very heavily based on the Colorcoder plugin by Valerij Primachenko.
Right now: Download the zipped-file and unzip it. Name the resulting folder "128T Log Viewer". Copy that folder to your Sublime Text Packages directory - you can find the Packages directory by choosing the Sublime Text▶Preferences▶Browse Packages. On a Mac, this would be /Users/<username>/Library/Application Support/Sublime Text 3/Packages directory. I have no idea what it is on Windows/Linux.
Eventually: Download the plugin via packageControl.
To properly work 128T Log Viewer needs an appropriately modified color scheme. On the first run the plugin will try its best to automatically modify your current scheme. ❕ The plugin will not actually modify the scheme but create a modified copy in a new directory called "128T-Log-Viewer" and apply it - note this directory is not the same as the one you created if you installed manually using the zip file.
You can use Tools▶Packages▶128T Log Viewer▶ Tweak Log Viewer on current color scheme (or CTRLSHIFTP it) to modify the colors a bit (you can change the lightness and saturation).
Uninstalling will cause Sublime Text to generate an error about a missing color scheme file. That's because your general User settings for Sublime Text have been changed to use the 128T Log Viewer's color scheme instead of your original. So go to Sublime Text▶Preferences▶Settings, and in the User settings remove or comment out the "color_scheme" setting line. Your original color scheme should also be in that User settings under "original_color_scheme" - you can change the name of this to "color_scheme" and everything should be right as rain.
You can turn the highlighting off per view via View▶128T Log Viewer this view.
The 128T Log Viewer also might slow down the editor when highlighting huge files, so it will turn itself off once the file has exceeded the max_size (the check happens when you save the file or reactivate the view). You can force it to highlight the file nevertheless via said menu item (which will read Colorcoding may hurt performance, File is large now)
Default (faster) highlighting method makes the undo work letterwise, you can change this by setting use_fast_highlighting_but_undo_typing_letterwise to false. The 128T Log Viewer will then use alternative engine, which does not interfere with undo, but work somewhat slower on large files. You might want to tune max_size lower then.
Finally ❗ if you use some plugins which change the color scheme based on time, or filename, or modify the schemes you better turn the auto_apply_on_scheme_change off, or the plugin conflict may result in an endless loop which will lock the editor. You can always change the settings even when Sublime Text is not running.
