cfget - get values from a config file


cfget [options] section/key
cfget [options] --dump=STYLE [section/key [section/key...]]
cfget [options] --template=STYLE [infile [outfile]]


Get values from a config file.

cfget is a simple tool to read values from configuration files. It is useful, for example, to create configurable shellscripts or makefiles.

It can also be configured to support virtual configuration values that, if not present in the config file, are automatically computed from the existing values. This makes it convenient, for example, to get a "duration" value from a configuration file that only contains a "start date" and an "end date".

-C file, --cfg=file
config file to read; the option can be given more than once to read more than one file. If missing, read a colon separated list from the CFGET_CFG env variable.
-P file, --plugin=file
list of plugin files or directories to load. The option can be given more than once to read more than one file. If missing, read a colon separated list from the CFGET_PLUGINS env variable.
-d name, --dump=name
dump the contents of the database using the given style. Use '--dump=list' for a list of available styles. If one or more paths are provided in the command line, dump only those paths, otherwise dump all.
-t name, --template=name
read a template file, expand template placeholders using the configuration data and output the result. Use '--template=list' for a list of available styles.
-f name, --format=name
use a custom configuration file format (default: ini). Use '--format=list' for a list of available formats. The CFGET_FORMAT environment value, if defined, can be used to provide a different default value.
-r path, --root=path
restrict all work to values under the given path
