NinjaParser 0.0.2

Parse .ninja_log files and print statistics.

NinjaParser

NinjaParser is a Python module to parse .ninja_log files and print build times.

If you have been complaining about long build times you may have switched to ninja from make. If not, you should give it a try. Along with being faster, ninja also provides a log file, .ninja_log containing timings for each built object. This information can be helpful to understand the bottlenecks in your building process. However, this file needs to be parsed to be comprehensible. NinjaParser prints a sorted list of built times with percentages for the top ten objects. You can also use -f option to filter objects that you want to print aggregated stats.

Usage

ninjaparser [-h] [-t TOP] [-f FILTER] [path ...]

Parse .ninja_log files.

positional arguments:
  path                  Path to .ninja_log file or the directory that contains it. Default is the current directory. (default: None)

optional arguments:
  -h, --help            show this help message and exit
  -t TOP, --top TOP     Print only top `n` items. Prints top 10 by default. Use -t -1 to print all. (default: 10)
  -f FILTER, --filter FILTER
                        Print aggregated stats for objects that includes the filter. Default is an empty string, no filtering. (default: )
