X.G.2.1 Ruby programming

In this case, most of the VBA programming of post-processing operations has been replaced by corresponding code in “TESTSAT/VBARUBYEX/RUBY” directory. This code is loaded through the “main.rb” main file. This file looks as follows:

One makes the following comments:

• The first lines update the list of directories from which ruby files and extensions shall be loaded. You must change these lines according to the local configuration of your computer. Note that the first directory added to the list is defined relative to the current working directory. The rest of the programming assumes that the working directory is the one in which “PostProject.xlsm” is located. A special VBA command in “PostProject.xlsm” has been added to ensure it is the case.
• The following lines redirect standard outputs to “main.log” file. This can be handy when you have a bug and you want to retrieve ruby error messages.
• Finally, the lines that follow perform “require” statements that load the programmed modules. The “postProject” require corresponds to most of the post-processing programming.

Note that the example we provide here depends on the availability of “FeResPost” and “sqlite3” ruby extensions. The example will not work on your computer if these two modules are not properly installed.
