PyFoam.ThirdParty.Gnuplot.gp_macosx module

gp_macosx – an interface to the command line version of gnuplot used under Mac OS X.

The only difference between this interface and gp_unix is that default_term is ‘aqua’.

This file implements a low-level interface to gnuplot. This file should be imported through gp.py, which in turn should be imported via ‘import Gnuplot’ rather than using these low-level interfaces directly.

class PyFoam.ThirdParty.Gnuplot.gp_macosx.GnuplotOpts[source]

Bases: object

The configuration options for gnuplot on Mac OS X.

See the gp_unix.py for documentation on all of the parameters.

class PyFoam.ThirdParty.Gnuplot.gp_macosx.GnuplotProcess(persist=None, quiet=False)[source]

Bases: object

Unsophisticated interface to a running gnuplot program.

This represents a running gnuplot program and the means to communicate with it at a primitive level (i.e., pass it commands or data). When the object is destroyed, the gnuplot program exits (unless the ‘persist’ option was set). The communication is one-way; gnuplot’s text output just goes to stdout with no attempt to check it for error messages.

Members:

‘gnuplot’ – the pipe to the gnuplot command.

Methods:

‘__init__’ – start up the program.

‘__call__’ – pass an arbitrary string to the gnuplot program,
followed by a newline.

‘write’ – pass an arbitrary string to the gnuplot program.

‘flush’ – cause pending output to be written immediately.

‘close’ – close the connection to gnuplot.

Determine whether gnuplot recognizes the option ‘-persist’.

If the configuration variable ‘recognizes_persist’ is set (i.e., to something other than ‘None’), return that value. Otherwise, try to determine whether the installed version of gnuplot recognizes the -persist option. (If it doesn’t, it should emit an error message with ‘-persist’ in the first line.) Then set ‘recognizes_persist’ accordingly for future reference.
