AnalysePlugin

Shorten your time of reading mega bytes of log files! DE 2016-01 Supporting Don HO's NotePad++ see http://notepad-plus-plus.org/ This sources are a dockable pattern search plugin for Notepad++ version 5.1 or later. With this plugin you can search for multiple patterns in any of the opened documents in NotePad++. You may want to tune your search using all fancy tricks from NPP like regular expressions or escaped patterns and give each of the searches different colors. The result will be stored in a dockable window in same ordering as in the origin and a double click allows you to jump to the original position. It is designed to treat log-files of typical size like 60MB. More features can be found in the help dialogue of the plugin. For generating the dll file I use a msdev compiler. If you like to port it to other OSs just let me know your changes and I'll incorporate it. Best Regards, Mattes H.

jq

Lightweight and flexible command-line JSON processor

jq is like sed for JSON data - you can use it to slice, filter, map and transform structured data with the same ease that sed, awk, grep and friends let you play with text. jq is written in portable C, and it has zero runtime dependencies. You can download a single binary, scp it to a far away machine of the same type, and expect it to work. jq can mangle the data format that you have into the one that you want with very little effort, and the program to do so is often shorter and simpler than you'd expect. Data in jq is represented as streams of JSON values - every jq expression runs for each value in its input stream, and can produce any number of values to its output stream. jq filters run on a stream of JSON data. The input to jq is parsed as a sequence of whitespace-separated JSON values which are passed through the provided filter one at a time. The output(s) of the filter are written to standard out, again as a sequence of whitespace-separated JSON data.
