Configuring Codyze

There are two ways of configuring Codyze, through command line options or a configuration file.

If both are present, the command line options take precedence over the configuration file. For list and map type options, the data from the configuration file can be overwritten if the normal option (e.g. --option-name) is used. To append the data from the command line to the one from the configuration file, use the additions option (e.g. --option-name-additions)

Command Line Interface

There are three execution modes in which Codyze can run:

  • Command line mode:
    Non-interactive command line client, accepts arguments from command line and runs analysis
  • Language server protocol mode:
    This mode is for IDE support and binds to stdout as a server for Language Server Protocol (LSP)
  • Interactive console mode:
    The text based user interface (TUI) is an interactive console that allows exploring the analyzed source code by manual queries

Subcommands are used to enter the modes (analyze, lsp, or interactive).

The help and version message can be displayed with -h and -V respectively. The full help is only available if a subcommand is specified.

Configuration File

The configurations can also be defined with a JSON configuration file. Use the option --config=<filepath> to specify the path to the config file. The configuration from ./codyze.json will always be loaded if no other file is specified.

Relative paths in the configuration file are resolved relative to the configuration file location.

The configuration structure separates the options by subcommand as seen below.

{
  "analyze": {
    "source": "src"
  },
  "lsp": {
    "source": "other-src"
  }
}
The value of the option is taken from the object which corresponds to the subcommand used for the execution. This means if codyze analyze is called, source would be src, and if codyze lsp is called, source would be other-src. An exemplary configuration file can also be found in the GitHub repository.

List of Configurations

This is a list of all available configurations, their descriptions and their respective name. The names are the same for the configuration file and the CLI options.

./ denotes the working directory in which Codyze was started.

Key Value Description Default Value
source Path[] Path to the to be analyzed files or directories. [./]
disabled-source Path[] Path to files or directories which should not be analyzed. Symbolic links are not followed when filtering out these paths. []
output String Output file in which results are written. Use "-" to print to stdout. findings.sarif
timeout long Terminates analysis after given minutes. 120
spec Path[] Paths to Mark rule files. [./]
disabled-spec Path[] The specified Mark rules will be excluded from being parsed and processed. The rule has to be specified by its fully qualified name (package.rule). If there is no package name, specify rule as .rule. Use package.* to disable an entire package. []
no-good-findings boolean Disables output of positive findings. false
pedantic boolean Activates pedantic analysis mode. In this mode, Codyze analyzes all MARK rules and report all findings. This option overrides "disabled-mark-rules" and "no-good-finding" and ignores any Codyze source code comments. false
executor String Manually choose Executor to use with the given spec files. If unspecified, Codyze randomly selects an executor capable of evaluating the given specification files. randomly selected
typestate DFA/WPDS Specify typestate analysis mode.
DFA: Deterministic finite automaton (faster, intraprocedural)
WPDS: Weighted pushdown system (slower, interprocedural)
DFA
additional-languages String[] Specify programming languages of to be analyzed files (full names). []
unity boolean Only relevant for C++. A unity build refers to a build that consolidates all translation units into a single one, which has the advantage that header files are only processed once, adding far less duplicate nodes to the graph. false
type-system-in-frontend boolean If false, the type listener system is only activated once the frontends are done building the initial AST structure. This avoids errors where the type of a node may depend on the order in which the source files have been parsed. true
default-passes boolean Adds all default passes in cpg (1. FilenameMapper, 2. TypeHierarchyResolver, 3. ImportResolver, 4. VariableUsageResolver, 5. CallResolver, 6. EvaluationOrderGraphPass, 7. TypeResolver). true
passes String[] Register these passes to be executed in the specified order. Please specify the passes with their fully qualified name. []
debug-parser boolean Enables debug output generation for the cpg parser. false
disable-cleanup boolean Switch off cleaning up TypeManager memory after analysis, set to true only for testing. false
code-in-nodes boolean Should the code of a node be shown as parameter in the node. false
annotations boolean Enables processing annotations or annotation-like elements. false
fail-on-error boolean Should parser/translation fail on parse/resolving errors (true) or try to continue in a best-effort manner (false). false
symbols Map Definition of additional symbols. {}
parallel-frontends boolean If true, the ASTs for the source files are parsed in parallel, but the passes afterwards will still run in a single thread. This speeds up initial parsing but makes sure that further graph enrichment algorithms remain correct. false
match-comments-to-nodes boolean Controls whether the CPG frontend shall use a heuristic matching of comments found in the source file to match them to the closest AST node and save it in the comment property. false
analyze-includes boolean Enables parsing of include files. If includePaths are given, the parser will resolve symbols/templates from these in include but not load their parse tree. false
includes Path[] Paths containing include files. []
enabled-includes Path[] If includes is not empty, only the specified files will be parsed and processed in the cpg, unless it is a part of the disabled list, in which it will be ignored. []
disabled-includes Path[] If includes is not empty, the specified includes files will be excluded from being parsed and processed in the cpg. The disabled list entries always take priority over the enabled list entries. []
