analizo-metrics-batch - processes several source code directories in batch
analizo metrics-batch [OPTIONS] [<input> [<input> ...]]
Processes several source code directories in batch running analizo metrics for each and optionally consolidating the results in a single data file.
analizo metrics-batch is useful when you want to analyze several projects at once, or several different versions of the same project. You pass a list of directories in the command line and each one will be analyzed as a separate project. If no directories are passed in the command line, all of the subdirectories of the current directory will be analized.
For example, suppose you want to process 5 consecutive releases of myproject, from version 0.1.0 to 0.5.0.
First you unpack the release tarballs for those versions in a directory, say /tmp/analysis:
$ ls -1 /tmp/analysis myproject-0.1.0 myproject-0.2.0 myproject-0.3.0 myproject-0.4.0 myproject-0.5.0
Then you change to that directory, and then run analizo metrics-batch:
$ cd /tmp/analysis $ analizo metrics-batch
analizo metrics-batch will collect the metrics data in a single .csv file, that you can import in spreadsheet software or statistical packages.
analizo metrics-batch is part of the analizo suite.
- --parallel N, -p N
Activates support for parallel processing, using N concurrent worker processes. Usually you will want N to be less than or equal to the number of CPUs in your machine.
Note that analizo metrics extraction is a CPU-intensive process, so setting N as the exacty number of CPUs you have may bring your machine to an unusable state.
- --output <file>, -o <file>
Write output to <file>. Default is to write to metrics.csv. That file can then be opened in data analysis programs.
- --quiet, -q
Suppresses messages to standard output.
