honeybee_plus.radiance.command.pyRad.pyRadLib.pyrad_proc.ProcMixin[source]¶ Bases:
objectProcess and pipeline management for Python Radiance scripts
-
call_many(cmdlines, actstr, _in=None, out=None, universal_newlines=False)[source]¶ Create a series of N processes, chained via pipes, possibly with an incoming and outgoing pipe at each end. Returns a tuple of N subprocess.Popen instances. Depending on the values of _in and out, the first and last may be available to write to or read from respectively. Most arguments are equivalent to call_one(), with - cmdlines
a list of N command argument lists
_in / out applying to the ends of the chain.
If _in or out is PIPE, the caller should call p.wait() on all returned Popen instances after writing to and closing the first one.
-
call_one(cmdl, actstr, _in=None, out=None, universal_newlines=False)[source]¶ - Create a single subprocess, possibly with an incoming and outgoing
pipe at each end. - cmdl
A list of strings, leading with the name of the executable (without the *.exe suffix), followed by individual arguments.
actstr A text string of the form “do something”. Used in verbose mode as “### do someting
- ### [command line]”
Used in error messages as “Scriptname: Unable to do something”.
_in / out What to do with the input and output pipes of the process: * a filename as string
Open file and use for reading/writing.
a file like object Use for reading/writing
PIPE Pipe will be available in returned object for reading/writing.
None (default) System stdin/stdout will be used if available
If _in or out is a PIPE, the caller should call p.wait() on the returned Popen instance after writing to and closing it.
-
call_two(cmdl_1, cmdl_2, actstr_1, actstr_2, _in=None, out=None, universal_newlines=False)[source]¶ Create two processes, chained via a pipe, possibly with an incoming and outgoing pipe at each end. Returns a tuple of two Popen instances. Arguments are equivalent to call_one(), with _in and out applying to the ends of the chain. If _in or out is PIPE, the caller should call p.wait() on both returned popen instances after writing to and closing the first on .
