| # encoding: utf-8
# api: streamtuner2
# title: win32/subprocess
# description: Utilizes subprocess spawning or win32 API instead of os.system
# version: 0.3.1
# version: 0.4
# depends: streamtuner2 > 2.2.0, python >= 2.7
# priority: optional
# config:
# { name: cmd_spawn, type: select, select: "popen|shell|call|execv|spawnv|pywin32|win32api|system", value: popen, description: Spawn method }
# { name: cmd_flags, type: select, select: "none|nowait|detached|nowaito|all|sw_hide||sw_minimize|sw_show", value: nowait, description: Process creation flags (win32) }
# { name: cmd_flags, type: select, select: "none|nowait|detached|nowaito|all|sw_hide|sw_maximize|sw_minimize|sw_show", value: nowait, description: Process creation flags (win32) }
# type: handler
# category: io
#
# Overrides the action.run method with subprocess.Popen() and a bit
# cmdline parsing. Which mostly makes sense on Windows to avoid some
# `start` bugs, such as "http://.." arguments getting misinterpreted.
# Also works on Linux, though with few advantages and some gotchas.
#
# +------------------+-----+------+---------+-------+----------------------+
# | VARIANT | SYS | ARGS | FLAGS | PATHS | NOTES |
# +------------------+-----+------+---------+-------+----------------------+
# | subprocess.popen | * | [] | all | base | Most compatible |
# | subprocess.shell | lnx | str | all | base | Linux only? |
# | subprocess.call | * | [] | all | base& | May block Gtk thread |
# | os.execv | w32 | s/[] | - | full& | fork+exec |
# | os.spawnv | lnx | s/[] | nowait | full& | ? |
# | pywin32.CreatePr | w32 | str | detached| full | Few parameters used |
# | win32api.WinExec | w32 | str | sw_show | base | Mostly like `start`? |
# | win32api.WinExec | w32 | str | sw_* | base | Mostly like `start`? |
# | system/default | * | str | - | base | normal action.run() |
# +------------------+-----+------+---------+-------+----------------------+
#
# · The flags are only supported on Windows. The FLAGS column just lists
# recommended defaults. Will implicitly be `none` for Linux.
# · Note that for Linux, you should decorate player commands with "&" and
# use absolute paths for call/exec/spawn to work as expected. |
