SAMU(1) General Commands Manual SAMU(1) NAME samu -- ninja-compatible build tool SYNOPSIS samu [-C dir] [-d debugflag] [-f buildfile] [-j maxjobs] [-k maxfail] [-l maxload] [-w warnflag=action] [-nv] [target...] samu [-C dir] [-f buildfile] -t clean [-gr] [target...] samu [-C dir] [-f buildfile] -t compdb [-x] [rule...] samu [-C dir] [-f buildfile] -t commands [target...] samu [-C dir] [-f buildfile] -t graph [target...] samu [-C dir] [-f buildfile] -t query [target...] samu [-C dir] [-f buildfile] -t targets [depth [maxdepth]] samu [-C dir] [-f buildfile] -t targets rule [rulename] samu [-C dir] [-f buildfile] -t targets all samu -t list DESCRIPTION samu loads a build manifest from buildfile and rebuilds targets if they are out of date. If no targets are specified, the manifest's default targets are built. If there are no default targets, the leaf nodes of the dependency graph are built (outputs that have no consuming action). Targets are out of date if they are older than the generating action's newest input, they have no entry in the build log, or if the command to build the target differs from what was used previously. Targets built with generator rules are not rebuilt if the command changes. If the clean tool is used, the targets are cleaned instead. When a target is cleaned, it is removed and are all of its inputs are cleaned. Targets with no generating actions are never removed. Targets built with generator rules are only removed if -g is specified. If the commands tool is used, a list of shell commands used to build the specified (or default) targets is printed. If the compdb tool is used, a compilation database (https://clang.llvm.org/docs/JSONCompilationDatabase.html) is printed instead. If the graph tool is used, a graphviz dot file is printed instead. If the query tool is used, the inputs and outputs of the targets are printed instead. If the targets tool is used, a list of targets will be displayed, ei- ther by rule or by depth. The first argument determines how the tar- gets will be displayed: depth An indented tree of targets will be displayed, starting by the root targets (those with no dependent targets), up to the depth specified by maxdepth (defaults to 1). rule If rulename is given, a list of targets using the given rule will be displayed. Otherwise, a list of source files will be displayed. all A list of all targets will be displayed. If the list tool is used, a list of available tools is displayed. OPTIONS -C Switch working directory to dir before building. -d Enable a debugging option. This flag may be specified multiple times to enable multiple debugging options. Possible values for debugflag are: explain Print messages explaining why outputs were dirty. keepdepfile Don't remove $depfile after it was parsed. keeprsp Don't remove $rspfile after job completion or failure. -f Load manifest from buildfile instead of build.ninja. -j Run up to maxjobs jobs in parallel (default based on number of CPUs). If zero, allow unlimited concurrent jobs. -k Allow up to maxfail job failures. If negative or zero, allow any number of job failures. -l Do not spawn new jobs if the system load percentage is greater than maxload. If zero, spawn jobs as soon as possible. -n Do not actually execute the commands or update the log. -v Print full commands instead of just description. -w Control how certain errors are handled. If warnflag is dupbuild, action specifies what to do if an output is listed in multiple build edges. If action is err, treat it like an error and fail. If action is warn, only print a diagnostic message. -t Instead of building, invoke a subtool. All arguments and flags after the subtool are interpreted by the subtool. The cur- rently supported subtools are clean, commands, compdb, graph, query, and targets. -g When cleaning, also clean outputs of generator actions. -r targets are interpreted as rules, and all outputs of actions with the specified rule types will be cleaned instead. -x When printing a compilation database, replace @$rspfile with $rspfile_content (with <blank> in place of <newline>). ENVIRONMENT SAMUFLAGS Options for samu that get applied before those specified on the command-line. The only options allowed in SAMUFLAGS are -v, -j and -l. NINJA_STATUS The status output printed to the left of each rule de- scription, using printf-like conversion specifiers. If unset, the default is "[%s/%t] ". Available conversion specifiers: %s Number of started jobs. %f Number of finished jobs. %t Total number of jobs. %r Number of running jobs. %u Number of remaining jobs. %p Percentage of completed jobs. %o Rate of finished jobs per second (to 1 decimal place). %e Elapsed time in seconds (to 3 decimal places). %% The '%' character.
