peri.conf

The default values for the global package configuration are provided in peri.conf.default_conf. The configuration variables are described here:

Variable name	Default value	Description
fftw-threads	-1	Number of threads for fftw to use, -1 indicates all available
fftw-planning-effort	FFTW_MEASURE	One of (FFTW_ESTIMATE, FFTW_MEASURE, FFTW_PATIENT) where options to the right take longer the first time but are faster in subsequent evaluations.
fftw-wisdom	~/.peri-wisdom.pkl	Location of file in which to store wisdom. Wisdom is the results of fftw benchmarking itself, allowing it to run as fast as possible.
log-filename	~/.peri.log	Name of file for logging.
log-to-file	False	Whether or not to actually save logs to a file as well
log-colors	False	Display logs in color (supported by xterm256)
verbosity	vvv	Level of verbosity for logs, the more v’s the more verbose

peri.conf.create_default_conf()

Dump the default_conf to the configuration file

peri.conf.get_conf_filename()

The configuration file either lives in ~/.peri.json or is specified on the command line via the environment variables PERI_CONF_FILE

peri.conf.load_conf()

Load the configuration with the priority:

1. environment variables
2. configuration file
3. defaults here (default_conf)

peri.conf.read_environment()

Read all environment variables to see if they contain PERI

peri.conf.transform(v)

Translate environment variables to ones corresponding to keys in the configuration. In particular, env variables may be made with “PERI_”+key_name: fftw-threads = PERI_FFTW_THREADS. Each env var is later checked to see if it has to do with PERI
