NAME

       cf-promises - validate and analyze CFEngine policy code

SYNOPSIS

       cf-promises [OPTION]...  [FILE]

DESCRIPTION

       cf-promises is a tool for checking CFEngine policy code. It operates by first parsing policy code checing
       for  syntax  errors. Second, it validates the integrity of policy consisting of multiple files. Third, it
       checks for semantic errors, e.g. specific attribute set rules. Finally, cf-promises  attempts  to  expose
       errors  by  partially evaluating the policy, resolving as many variable and classes promise statements as
       possible. At no point does cf-promises make any changes to the system.

OPTIONS

       --eval-functions, -
              Evaluate functions during syntax checking (may  catch  more  run-time  errors).  Possible  values:
              'yes', 'no'. Default is 'yes'

       --show-classes, -
              Show discovered classes, including those defined in common bundles in policy

       --show-vars, -
              Show  discovered  variables, including those defined without dependency to user-defined classes in
              policy

       --help, -h
              Print the help message

       --bundlesequence, -b
              Use the specified bundlesequence for verification

       --debug, -d
              Enable debugging output

       --verbose, -v
              Output verbose information about the behaviour of the agent

       --dry-run, -n
              All talk and no action mode - make no changes, only inform of promises not kept

       --version, -V
              Output the version of the software

       --file, -f
              Specify an alternative input file than the default

       --define, -D
              Define a list of comma separated classes to be defined at the start of execution

       --negate, -N
              Define a list of comma separated classes to be undefined at the start of execution

       --inform, -I
              Print basic information about changes made to the system, i.e. promises repaired

       --diagnostic, -x
              Activate internal diagnostics (developers only)

       --reports, -r
              Generate reports about configuration and insert into CFDB

       --policy-output-format, -p
              Output the parsed policy. Possible values: 'none', 'cf', 'json'. Default is 'none'. (experimental)

       --syntax-description, -s
              Output a document describing the available syntax elements of CFEngine. Possible  values:  'none',
              'json'. Default is 'none'.

       --full-check, -c
              Ensure full policy integrity checks

       --warn, -W
              Pass comma-separated <warnings>|all to enable non-default warnings, or error=<warnings>|all

       --legacy-output, -l
              Use legacy output format

       --color, -C
              Enable  colorized  output.  Possible  values:  'always',  'auto',  'never'. If option is used, the
              default value is 'auto'

       --tag-release, -T
              Tag a directory with promises.cf with cf_promises_validated and cf_promises_release_id

CFENGINE

       CFEngine  provides  automated  configuration  management  of  large-scale  computer  systems.  A   system
       administrator  describes  the  desired state of a system using CFEngine policy code. The program cf-agent
       reads policy code and attempts to bring the current system state to the desired state  described.  Policy
       code  is  downloaded by cf-agent from a cf-serverd daemon. The daemon cf-execd is responsible for running
       cf-agent periodically.
       Documentation for CFEngine is available at http://cfengine.com/documentation/.

PROMISE THEORY

       CFEngine is built on principles from promise theory, proposed by Mark Burgess in 2004. Promise theory  is
       a  model  of  voluntary  cooperation  between  individual,  autonomous actors or agents who publish their
       intentions to one another in the form of promises. A promise is a declaration of intent whose purpose  is
       to  increase  the recipient's certainty about a claim of past, present or future behaviour. For a promise
       to increase certainty, the recipient needs to trust the promiser, but trust can  also  be  built  on  the
       verification  that  previous  promises  have  been  kept,  thus trust plays a symbiotic relationship with
       promises.
