NAME infer - static analysis for Java and C/C++/Objective-C/Objective-C++ SYNOPSIS infer analyze [options] infer capture [options] infer compile [options] infer help [options] infer explore [options] infer report [options] infer reportdiff [options] infer run [options] infer --compilation-database[-escaped] file [options] infer [options] -- compile command infer [options] DESCRIPTION Infer is a static analyzer. Given a collection of source files written in Java or in languages of the C family, and a command to build them, infer produces a list of potential issues. Infer consists of a collection of tools referenced in the SEE ALSO section of this manual. See their respective manuals for more information. When run without a subcommand, and if a compilation command is specified via the -- option or one of the --clang-compilation-database[-escaped] options, then infer behaves as infer-run(1). Otherwise, infer behaves as infer-analyze(1). OPTIONS Every infer command accepts the arguments from all the other infer commands. Options are read from the .inferconfig file, then from the INFER_ARGS environment variable, then from the command line. Options in INFER_ARGS take precedence over options in .inferconfig, and options passed on the command line take precedence over options in INFER_ARGS. See the ENVIRONMENT and FILES sections of this manual for more information. Options can be specified inside an argument file file by passing @file as argument. The format is one option per line, and enclosing single ' and double " quotes are ignored. Options without a default value (e.g., --linter) and options with list-like values (e.g., --Xbuck) all have a corresponding --option-reset flag that resets their values to nothing or the empty list, respectively. For instance, --Xbuck-reset will cancel any previous --Xbuck option passed to infer. See the manuals of individual infer commands for details about their supported options. The following is a list of all the supported options (see also --help-full for options reserved for internal use). --annotation-reachability Activates: checker annotation-reachability: Given a pair of source and sink annotation, e.g. `@PerformanceCritical` and `@Expensive`, this checker will warn whenever some method annotated with `@PerformanceCritical` calls, directly or indirectly, another method annotated with `@Expensive` (Conversely: --no-annotation-reachability) See also infer-analyze(1). --annotation-reachability-custom-pairs json Specify custom sources/sink for the annotation reachability checker Example format: for custom annotations com.my.annotation.{Source1,Source2,Sink1} { "sources" : ["Source1", "Source2"], "sink" : "Sink1" } See also infer-analyze(1). --annotation-reachability-cxx json Specify annotation reachability analyses to be performed on C/C++/ObjC code. Each entry is a JSON object whose key is the issue name. "sources" and "sinks" can be specified either by symbol (including regexps) or path prefix. "sinks" optionally can specify "overrides" (by symbol or path prefix) that block the reachability analysis when hit. Example: { "ISOLATED_REACHING_CONNECT": { "doc_url": "http:://example.com/issue/doc/optional_link.html", "sources": { "desc": "Code that should not call connect [optional]", "paths": [ "isolated/" ] }, "sinks": { "symbols": [ "connect" ], "overrides": { "symbol_regexps": [ ".*::Trusted::.*" ] } } } } This will cause us to create a new ISOLATED_REACHING_CONNECT issue for every function whose source path starts with "isolated/" that may reach the function named "connect", ignoring paths that go through a symbol matching the OCaml regexp ".*::Trusted::.*". See also infer-analyze(1). --annotation-reachability-cxx-sources json Override sources in all cxx annotation reachability specs with the given sources spec See also infer-analyze(1). --annotation-reachability-only Activates: Enable annotation-reachability and disable all other checkers (Conversely: --no-annotation-reachability-only) See also infer-analyze(1). --append-buck-flavors +string Additional Buck flavors to append to targets discovered by the --buck-compilation-database option. See also infer-capture(1). --no-biabduction Deactivates: checker biabduction: This analysis deals with a range of issues, many linked to memory safety. (Conversely: --biabduction) See also infer-analyze(1). --biabduction-only Activates: Enable biabduction and disable all other checkers (Conversely: --no-biabduction-only) See also infer-analyze(1). --bo-debug int Debug level for buffer-overrun checker (0-4) See also infer-analyze(1). --bo-field-depth-limit int Limit of field depth of abstract location in buffer-overrun checker See also infer-analyze(1). --bootclasspath string Specify the Java bootclasspath See also infer-capture(1). --buck-blacklist +regex Skip capture of files matched by the specified regular expression. Only the clang, non-compilation-database Buck integration is supported, not Java. See also infer-capture(1) and infer-run(1). --buck-clang Activates: Buck integration for clang-based targets (C/C++/Objective-C/Objective-C++). (Conversely: --no-buck-clang) See also infer-capture(1). --buck-compilation-database { no-deps | deps } Buck integration using the compilation database, with or without dependencies. Only includes clang targets, as per Buck's #compilation-database flavor. See also infer-capture(1). --buck-compilation-database-depth int Depth of dependencies used by the --buck-compilation-database deps option. By default, all recursive dependencies are captured. See also infer-capture(1). --buck-java-flavor Activates: Buck integration for Java which uses the buck flavor #infer-java-capture instead of genrules like buck-java. (Conversely: --no-buck-java-flavor) See also infer-capture(1). --buck-java-flavor-suppress-config Activates: Suppress setting buck config values for the infer binary and its version in the buck-java-flavor integration. (Conversely: --no-buck-java-flavor-suppress-config) See also infer-capture(1). --buck-java-heap-size-gb int Explicitly set the size of the Java heap of Buck processes, in gigabytes. See also infer-capture(1). --buck-merge-all-deps Activates: Find and merge all infer dependencies produced by buck. Use this flag if infer doesn't find any files to analyze after a successful capture. Only valid for --buck-clang. (Conversely: --no-buck-merge-all-deps) See also infer-capture(1). --buck-targets-blacklist +regex Skip capture of buck targets matched by the specified regular expression. Only valid for --buck-compilation-database. See also infer-capture(1) and infer-run(1). --bufferoverrun Activates: checker bufferoverrun: InferBO is a detector for out-of-bounds array accesses. (Conversely: --no-bufferoverrun) See also infer-analyze(1). --bufferoverrun-only Activates: Enable bufferoverrun and disable all other checkers (Conversely: --no-bufferoverrun-only) See also infer-analyze(1). --capture-blacklist regex Skip capture of files matched by the specified OCaml regular expression (only supported by the javac integration for now). See also infer-capture(1) and infer-run(1). --censor-report +string Specify a filter for issues to be censored by adding a 'censored_reason' field in the json report. Infer will not report censored issues on the console output and in report.txt, but tools that post-process the json report can take them into account. If multiple filters are specified, they are applied in the order in which they are specified. Each filter is applied to each issue detected, and only issues which are accepted by all filters are reported. Each filter is of the form: `::`. The first two components are OCaml Str regular expressions, with an optional `!` character prefix. If a regex has a `!` prefix, the polarity is inverted, and the filter becomes a "blacklist" instead of a "whitelist". Each filter is interpreted as an implication: an issue matches if it does not match the `issue_type_regex` or if it does match the `filename_regex`. The filenames that are tested by the regex are relative to the `--project-root` directory. The `` is a non-empty string used to explain why the issue was filtered. See also infer-report(1) and infer-run(1). --cfg-json file Path to CFG json file See also infer-analyzejson(1). --changed-files-index file Specify the file containing the list of source files from which reactive analysis should start. Source files should be specified relative to project root or be absolute See also infer-analyze(1). --clang-biniou-file file Specify a file containing the AST of the program, in biniou format.

See also infer-capture(1). --clang-blacklisted-flags +string Clang flags to filter out See also infer-capture(1). --clang-blacklisted-flags-with-arg +string Clang flags (taking args) to filter out See also infer-capture(1). --clang-compound-literal-init-limit int Limit after which initialization of compound types (structs and arrays) is not done element by element but using a builtin function that each analysis has to model. See also infer-analyze(1) and infer-capture(1). --clang-yojson-file file Specify a file containing the AST of the program, in yojson format. Please note you still need to provide a compilation command. See also infer-capture(1). --compilation-database +path File that contain compilation commands (can be specified multiple times) See also infer-capture(1). --compilation-database-escaped +path File that contain compilation commands where all entries are escaped for the shell, eg coming from Xcode (can be specified multiple times) See also infer-capture(1). --config-checks-between-markers Activates: checker config-checks-between-markers: [EXPERIMENTAL] Collects config checks between marker start and end.

ENVIRONMENT Extra arguments may be passed to all infer commands using the INFER_ARGS environment variable (see the OPTIONS section). INFER_ARGS is expected to contain a string of ^-separated options. For instance, calling `INFER_ARGS=--debug^--print-logs infer` is equivalent to calling `infer --debug --print-logs`. INFERCONFIG: Tells infer where to find the .inferconfig file. (See the FILES section) If INFER_STRICT_MODE is set to "1", then infer commands will exit with an error code in some cases when otherwise a simple warning would be emitted on stderr, for instance if a deprecated form of an option is used. FILES .inferconfig can be used to store infer options. Its format is that of a JSON record, where fields are infer long-form options, without their leading "--", and values depend on the type of the option: - for switches options, the value is a JSON boolean (true or false, without quotes) - for integers, the value is a JSON integer (without quotes) - string options have string values - path options have string values, and are interpreted relative to the location of the .inferconfig file - cumulative options are JSON arrays of the appropriate type Infer will look for an .inferconfig file in the current directory, then its parent, etc., stopping at the first .inferconfig file found.
