NAME

       dmypy - mypy daemon mode client

SYNOPSIS

       dmypy [OPTIONS...] COMMAND] [COMMAND OPTIONS ...]

DESCRIPTION

       Mypy  can  run as a long-running daemon (server) process allowing to perform type checking
       much faster, since program state cached from previous runs is kept in memory  and  doesn’t
       have  to  be  read  from  the  file system on each run. The server also uses finer-grained
       dependency tracking to reduce the amount of work that needs to be done.

       If you have a large codebase to check, running mypy using the mypy daemon  can  be  10  or
       more  times  faster  than  the regular command-line mypy tool, especially if your workflow
       involves running mypy repeatedly after small edits – which is often a good idea,  as  this
       way you’ll find errors sooner.

       Dmypy is a command-line client to send type-checking requests to the server.

COMMANDS

   start [--log-file FILE] [--timeout TIMEOUT] ARGS...
       Start a mypy daemon.

       Runs  a new mypy daemon, passing regular mypy flags to it.  If --log-file is used, directs
       daemon stdout/stderr to FILE.  --timeout specifies the server shutdown timeout in seconds.

   stop
       Stop a mypy daemon.

       Politely asks the currently running mypy daemon to go away.

   kill
       Kill a mypy daemon.

       Kills the process of the currently running mypy daemon.

   restart [--log-file FILE] [--timeout TIMEOUT] ARGS...
       Restart a mypy daemon.

       Stops the existing and then runs a new mypy daemon, passing regular mypy flags to it.   If
       --log-file  is used, directs daemon stdout/stderr to FILE.  --timeout specifies the server
       shutdown timeout in seconds.

   status [-v]
       Show a mypy daemon status.

       If -v or --verbose is used, prints detailed status.

   daemon [--timeout TIMEOUT] ARGS...
       Run a mypy daemon in the foreground, passing regular mypy flags to it.

       --timeout specifies the server shutdown timeout in seconds.

   check [-v] [--junit-xml JUNIT_XML] [--perf-stats-file PERF_STATS_FILE] FILE [FILE ...]
       Check some files.

       Tell the currently running mypy daemon to check some files. This requires  the  daemon  to
       already be running.

       -v, --verbose
              Print detailed status

       --junit-xml JUNIT_XML
              Write junit.xml to the given file

       --perf-stats-file PERF_STATS_FILE
              Write telemetry information to the given file

   recheck  [-v] [--junit-xml JUNIT_XML] [--perf-stats-file PERF_STATS_FILE] [--update FILE [FILE
       ...]] [--remove FILE [FILE ...]]
       Re-check the previous list of files, with optional modifications. This requires the daemon
       to already be running.

       -v, --verbose
              Print detailed status

       --junit-xml JUNIT_XML
              Write junit.xml to the given file

       --perf-stats-file PERF_STATS_FILE
              Write telemetry information to the given file

   run  [-v]  [--junit-xml  JUNIT_XML]  [--perf-stats-file  PERF_STATS_FILE]  [--timeout TIMEOUT]
       [--log-file FILE] ARGS...
       Check some files, (re)starting the daemon if necessary.

       -v, --verbose
              Print detailed status

       --junit-xml JUNIT_XML
              Write junit.xml to the given file

       --perf-stats-file PERF_STATS_FILE
              Write telemetry information to the given file

       --timeout TIMEOUT
              Server shutdown timeout (in seconds)

       --log-file FILE
              Direct daemon stdout/stderr to FILE

   hang
       Hang for 100 seconds.

OPTIONS

       -h, --help
              Show a help message and exit.

       --status-file STATUS_FILE
              Status file to retrieve daemon details to.

       -V, --version
              Show program’s version number and exit.
