  • Outline Mode in Gams-Mode for Emacs

    Let’s get to know the great things you can do with Gams-mode. In the previous post I showed how Gams-mode nicely colors your code, the syntax-highlighting. In this post we will look at the great way Gams-mode shows the results of your model run. This is done in the Gams-Outline mode.
    First run your model by hitting C-c C-s (C stands for Ctrl) or use the same command from the menu. Emacs will open a new window and you see how Gams solves your model. When Gams is finished you can hit F10 (or C-c C-v)  to show the listing

  • Emacs Goodies

    Often you have to repeat a series of keystrokes. That is probably boring if the number of repetitions is low, but gets really annoying if the number gets higher. A typical example is formatting data or text. Take the following text snippet where we have data coming from a comma separated file:
    A;410
    B;243
    C;134
    A;410
    B;324
    C;134
    A;410
    B;324
    C;134
    and you would like to have this text in the following format
    A        410,
    B        243,
    Emacs makes this a very easy job: Start the macro recording with C-x (  or F3 (the C stands for the Control

  • Syntax Coloring in Gams-Mode

    I suppose you have installed emacs and gams-mode for emacs (if not see my preceding posts) and now are eager to start working on your model.
    Let us start simple and get a model from the Gams-library. If you started emacs you are not in gams-mode (you can check this by looking at the menu bar: there is no gams-entry). If you load a gams model (with the extension “gms”), Emacs automatically turns on gams-mode and the gams entry appears in the menu bar (blue arrow). The first thing you probably notice is the syntax coloring. The coloring you will

  • Installing Gams-Mode for Emacs

    After installing Emacs (see my previous post), the next thing to do is install gams-mode. If you got Emacs running, installing gams-mode is not so difficult.
    First of all download gams-mode from Shiro Takeda’s website: You will find it here: gams-mode-download.
    Update: you can now directly install gams-mode from the package repository:
    • Alt-x and type ‘list-packages’
    • search for gams-mode
    • click on it and install.

    That’s all.

    The files are zipped and should be unzipped to a directory Emacs will find. I show you my settings (as usual, you can do it in another way).
    I have all my additional … Read the rest “Installing Gams-Mode for Emacs”
