# This file is read by nanoscale to determine which ports to listen

#
# Render servers
#
#	Server			Port		Usage
#	======			====		=====
#	nanovis			2000		production
#	vtkvis			2010		production
#	geovis			2015		testing
#	vmdshow			2018		testing
#	pymolproxy		2020		production
#
# The syntax is
#	register_server <name> <port> ?<flags>? {
#	    commands...
#	} {
#	    variables...
#       }
#
# Registers a server by <name> at port <port>.
# When a connection is made to <port>, <command> is run.
# Environment variables will be set before executing command.
#
# Note: Don't set DISPLAY here. nanoscale itself sets the DISPLAY
#	variable.
#
# Defaults:
#   - Server reads from file descriptor 0.
#   - Server writes to descriptor 1.
#   - Server stdout and stderr are redirected to a log file.

# PymolProxy --
#	Server Type	Molecular layouts using Pymol viewer
#	Port		2020
#	Threaded	yes
# Notes:
#	- Need PYMOL_SITE_PATH for parallelpiped box.py location.
#	- For debug tracing, redirect stderr of the proxy to a log file.

# VmdShow --
#	Server Type	Molecular layouts using VMD viewer (for mdshowcase)
#	Port		2018
#	Threaded	no
# Notes:
#	- Commands are sent directly to the VMD process that uses custom
#	  TCL code to process.
#	- Redirect input to descriptor 3: Otherwise VMD will get select hit.
#	- Redirect output to descriptor 4: Lots of information written to
#	  stdout and stderr of VMD.  Captured in log file.
#	- Executing binary without wrapper shell script. Requires VMDDIR set.
#	- Meshing programs surf and msms require explicit environment variables.
#	- Client doesn't send data files to VMD, but file paths.  Unlikely
#	  client will block on a large write.
