NAMEdmypy − mypy daemon mode client

SYNOPSISdmypy [OPTIONS...] COMMAND] [COMMAND OPTIONS ...]

DESCRIPTIONMypy 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.

stopStop a mypy daemon. Politely asks the currently running mypy daemon to go away.

killKill 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

hangHang 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.
