Nikos, I've known about python integration but was not aware of the g.gui.modeler. Since GRASS is only one of the tools I use, and not on all projects, I would like to learn when it would be more appropriate to use a python or wxGUI Graphical Modeler rather than a bash shell script. I'm not challenging the use of python or g.gui.modeler. I want to determine whether either (or both) have advantages -- to me -- over writing a shell script and using it directly rather than as input to wx.gui.modeler or a python script. After reading the g.gui.modeler page I understand what it does but its advantages over a plain shell script are not obvious to me. Pointers to more information might provide the answers.

Nozhan, You will find that you have more control working at the console, particularly when the wxGUI does not recognize files you want to use. The GUI can be quite useful, but working at the console is preferred by those who are used to working on consoles in linux, *BSD, and various unices. Also, you can write scripts to perform repetative or complex processes and run them from the command line. The GUI does not support this. Please note that (Python) scripting is possible via the GUI as well. There is a Python tab and a simple Python script editor integrated (since at least version 7.4). Simple examples are also included. I don't use them, so I don't have an opinion about their usability. There is also the wxGUI Graphical Modeler. It too has the script editor integrated. In 2008, I requested for such an option: https://trac.osgeo.org/grass/ticket/131. Not speaking Python at the time, I asked for help to learn. I think it can be a good starting point in Python scripting for GRASS GIS. The 'Help' menu offers links to various resources. Adding one or two more resources, like https://github.com/wenzeslaus/python-grass-addon, is meaningful. Nikos Either on a 'getting started' or wiki page is a list of commands to start grass. In your installation 'grass' and 'grass74' are synonymous. If you run multiple versions (e.g., 7.4.x and 7.5svn) then you want to assign each to a unique name. signature.asc Description: PGP signature ___ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user
Re: [GRASS-user] Possible Grass Bug
Dear Nozhan, d.mon can only be called from the black terminal window that also opens when you open GRASS GIS. If you then want to display raster or vector maps, you will also need to write the commands in the black terminal. If you want to display maps in the GUI (layer manager + map display) just use buttons, or go to data catalog and browse the map you want to display.

Please let me know if you need further information. Nozhan, How do you start grass? The default is to start with the GUI. In this case you already have the monitor wx0 running. Just for giggles, start grass with 'grass text'. When it loads apply the monitor display command 'd.mon start=wx0' and when you're finished, use 'd.mon stop=wx0' to close the monitor then enter 'exit' on the grass command line to kill the application.

[GRASS-user] Possible Grass Bug
Dear Grass members, I apologize for any inconvenience but I am not familiar with the bug system in Grass GIG. Please let me know if this e-mail needs to be sent to a different address. Recently, I started working with Grass GIS (version 7.4.0). At the moment, I am following the tutorial ``NCSU GIS/MEA582: Geospatial Modeling and Analysis". I came across the command ``d.mon" that does not work the way it is supposed to work. The issue is that d.mon start=wx0 does not initiate a new display window, nor does d.mon stop=wx0 terminate an existing window. Also, ``d.mon -l" or ``d.mon -p" show nothing. In all cases the commands are written in the CONSOLE window in the Layer Manager sub-window and when the Enter button is hit the following error message appears that ``Command 'd.mon' not yet implemented in the WxGUI. Try adding it as a command layer instead." It, also, needs to be mentioned that the ``d.rast map=elevation" shows the elevation map just fine. It is the d.mon that is not working! Please let me know if you need further information. P.S. I am running Grass GIS 7.4.0 on Ubuntu trsuty 14.04 (32 bit).
