− | A lot of the | + | A lot of the behaviour of the terminal is controlled by the file '''parameters.py'''. Different projects of mine require different parameters. There are several way to achieve this. The simplest to understand might be to have a different files for each project. You can do this if you want, starting from my parameter file. You can also use a secondary parameter file that overrides the settings in the first file. But right now I am working with a somewhat different method that seems easier to manage. This is the method in the supplied parameter file and the one that I will explain here. The parameter file is heavily commented and these comments should be read if you have questions. You can also search other files for parameters.xxx where xxx is the name of the parameter you are investigating. |
− | + | In the __init__ method after a couple of required lines that help hold the application there is a call to self.default_terminal_mode(). This subroutine sets a ton of parameters and this is enough to make the terminal run nicely. See the comments in the subroutine for more info. | |
− | + | I then have a call to a short ( so far ) subroutine self.computer_name_tweaks( ) This subroutine uses the already set parameter computername to tweak a few settings depending on the computer's name. | |
+ | this makes it easy for me to change the default parameters setting based on the computer I am using to run the program. Thus I can move the program around without changing the parameter file. | ||
− | + | Finally I make a call to a subroutine like: well_monitor_mode(). This is the file for an arduino project that monitors my water well pressure. This is a pretty complicated set up, because of the database access in the well monitor. For this documentation I will do a subroutine called tutorial_example_mode() which make the most basic changes from the default mode. | |
