GDL Editors on Linux

This entry is part 2 of 4 in the series GDL Gnu Data Language

For editing GDL / IDL .pro files on Linux you can of course use any Text Editor (gedit, vi) or the IDLDE, but the following could prove useful:

Kate is a text editor for the KDE desktop environment but looks just as good on a Gnome Desktop (Ubuntu default). Kate has built-in support for syntax highlighting .pro files. To install, search for Kate in the Ubuntu Software Centre, or at the command line use:

Opening a .pro file in Kate should show your syntax highlighting and some auto-completion.

You can also have a split view with a terminal panel so you can run GDL commands.

2. Emacs & IDLWAVE

The IDLWAVE website has some good instructions. First install emacs from the Ubuntu Software Center or at the command-line use:

Next install IDLWAVE at the command line with the following commands:

After installing IDLWAVE create a file named .emacs (dot emacs) in your home directory with the following content:

Open emacs (Applications > Accessories > Emacs 22) and notice the IDLWAVE menu. Notice the menu option for IDLWAVE > External > Start IDL shell. To get this to work you will need to create a symlink for the idl command pointing to the gdl program, as follows:

    Hello!
    I’m at the last step of trying to install idlwave on my mac computer and I’m confused as to what the last question is asking concerning the symlink. How exactly do I do that? Also with the step prior I created a file using textwrangler and named it test.emacs and copied and pasted the content and saved the file to my desktop. Am I supposed to do this?

    Thank you!

      Kalvin,
      You probably want to use the Terminal app and type the command to create the link e.g. sudo ln -s /usr/bin/gdl /usr/bin/idl
      For yout test.emacs file I would suggest saving it as .emacs rather than test.emacs and it should be saved in your home folder (e.g. /Users/Kalvin ) rather than your desktop. Finder does not show hidden files and folders without some work so you might be better learning a bit about using the command line and using Terminal. For example, tying ‘ls -al’ (without the quotes) in Terminal will show all files and folders in your home folder including the hidden . files such as .emacs
      Hope this helps,
      jonny

    Hello,
    I have installed the idlwave successfully on my Mac, but I don’t know how to make highlight syntax for the key words such like ‘plot’. Can you tell how to set it ?

    Thank you!
