NAME

       spark - examines SPARK programs and generates verification conditions

SYNOPSIS

       spark [OPTIONS] [ FILE_LIST or @METAFILE ]

DESCRIPTION

       The  Examiner  for  SPARK,  spark, analyses the given source files for errors and violations of the SPARK
       subset and (optionally) generates verification conditions and dead path conjectures necessary  for  proof
       of absence of run-time exceptions and partial correctness.

       This  manual  page only summarises the spark command-line flags, please refer to the full Examiner manual
       for further information.

OPTIONS

       These options do not quite follow the usual GNU command line syntax. All options start with a single dash
       instead of the usual two and they can also be abbreviated, as long as the abbreviation is unique. For ex‐
       ample -help can be abbreviated to -he but not -h as this clashes with -html.

       -source_extension=file_type
              Specifies source file extension (Default 'ada')

       -noindex_file, -index_file=file_spec
              Specifies the index file. By default no index file is used.

       -nowarning_file, -warning_file=file_spec
              Specifies the warning control file. By default no warning control file is used.

       -noconfig_file, -config_file=file_spec
              Specifies the Examiner configuration file. By default no configuration file is used.

       -noswitch
              Ignore the spark.sw file, if it exists.

       -nolistings, -listing_extension=file_type
              By default all listing files have the 'lst' extension. These options can be used to disable  list‐
              ing file generation or to change the default extension.

       -noreport_file, -report_file=file_spec
              By  default  the report will be named 'SPARK.REP'. These options can be used to change the default
              name or to disable report generation.

       -html, -html=dir_spec
              Generate HTML listings and report file.

       -output_directory=dir_spec
              Generate report, listing and proof files in the specified directory.

       -plain_output
              No dates, line or error numbers will appear in the output files.

       -language=L
              This can be one of 83, 95 (the default) or 2005.

       -profile=P
              Choose between the sequential (the default) or ravenscar language profile.

       -noduration
              Do not predefine Standard.Duration.

       -syntax_check
              Perform syntax check only. No semantic checks.

       -flow_analysis=TYPE
              Choose between information or data.

       -policy=TYPE
              Select security or safety policy for flow analysis.

       -vcg   Generate VCs.

       -dpc   Generate DPCs.

       -rules=CHOICE
              Select policy for generation of composite constant proof rules. Can be one of none (the  default),
              lazy, keen or all.

       -annotation_character=CHAR
              Select alternative annotation character. The default is '#'.

       -noecho
              Suppress screen output.

       -nosli Don't generate SLI files.

       -sparklib
              Use the standard SPARK library.

       -nostatistics, -statistics
              Append Examiner table usage statistics to the report file. By default we don't do this.

       -fdl_identifiers=OPTION
              Control  treatment  of FDL identifiers when found in SPARK source. Can be one of 'reject' (the de‐
              fault) or 'accept' or <string>.

       -version
              Print Examiner banner and statistics and then exit.

       -help  Print command line summary and options.

       -original_flow_errors
              Print information flow errors in original, less compact, format.

       -error_explanations=SETTING
              Print explanations after error messages. Settings can be off (the  default),  first_occurrence  or
              every_occurrence.

       -justification_option=TYPE
              Select policy for justification of errors. Values can be full (the default), brief or ignore.

       -casing, -casing=CHOICE
              Check casing for identifier references and check casing of package Standard identifiers. It is al‐
              so possible to specify i or s to check for only one of these.
