uni: a program to interface with the UniConf configuration system

NAME

uni - a program to interface with the uniConf configuration system

SYNOPSIS

uni get KEY [DEFAULT] uni set KEY [VALUE] uni xset KEY [VALUE] uni keys KEY uni hkeys KEY uni xkeys KEY uni dump KEY uni hdump KEY uni xdump KEY

DESCRIPTION

UniConf is the One True Configuration system that includes all the others because it has plugin backends and frontends. Or, less grandiosely, it's a lightweight, distributed, cacheable tree of strings. uni is used to interface directly with the UniConf system. It's primary use is for diagnostic purposes, but it can be used to add UniConf support to shell scripts.

ENVIRONMENT VARIABLE

UNICONF Before using uni, you must tell it which UniConf moinker you wish to query by setting this environment variable. Monikers are used to contact UniConf back-ends, be they a uniconfd server, or a local file. For example, they could be: o a filename (ini:/var/lib/app/config.ini), o or a network address, (tcp:open.nit.ca:4111).
COMMANDS
get Retreive the VALUE associated with the provided KEY within the UniConf database. If a DEFAULT is provided, this will be returned if the KEY has no associated VALUE. set Assign the provided VALUE the the provided KEY. UniConf provides no guarentee that the entry committed throughout the database. The next "get" command for this KEY may not return the most recently "set" value due to caching, or the existance of a read-only generator. xset Assign, to the provided KEY, the contents of the standard-input stream. Use this command to pipe information into the UniConf database. keys List all the sub-keys contained within the provided KEY. hkeys List all the sub-keys, recursively, contained within the provided KEY. Since any KEY may contain sub-keys, UniConf provides no guarentee that there are no circular references. xkeys List all the sub-keys contained within the provided KEY, which can contain wildcards. See the WILDCARDS section. dump List all the sub-keys and their values, contained within the provided KEY. hdump List all the sub-keys and their values, recursively, contained within the provided KEY. xdump List all the sub-keys and their values, contained within the provided KEY, which can contain wildcards.
WILDCARDS
A KEY looks just like a normal slash-delimited path. The root of the UniConf tree has a KEY named "/". Sub-keys can be accessed by names such as "/software/myapp/version". With wildcards, you can access more than one key at a time. * To access a sub-key within any one level of keys, use the asterix like so: "/software/*/version". This retrieves all keys of "version" that are one level beneath "/software". ... To access a sub-key anywhere beneath a key, use the ellipsis like so: "/.../version". This retrieves all keys of "version" that are zero or more levels beneath the root (i.e. any appearance of "version" within the database.
