Export Code to Another Project¶
Sometimes there are parts of a model that you would like to re-use in another AIMMS model. If it is a very generic component, you could choose to create an AIMMS library or an AIMMS module out of it. Please see the chapter “Organizing a Project Into Libraries” in the AIMMS The User’s Guide for more information about this. In the cases that you only want to quickly export/import a set of identifiers once, you can also use the export/import functionality in AIMMS.
Also, on this blog we will provide the AIMMS code where applicable as .ams files. You can import these into your existing projects with the instructions found below. In some cases where the whole project is needed (and not only some snippets), we will provide the whole project as an a .zip file.
Exporting a section¶
Before you start exporting, you should place all the identifiers you wish to export from your current model into one section in your AIMMS model. When you have done this, there are two possible ways of exporting this section:
Select the section in the model tree and select Export… in the edit menu
Use the source attribute of the section identifier to store the section in a separate file
The first option has the advantage that it requires less steps. However, the second approach has the advantage that you can share code among projects.
If you do not perform the last two steps, all identifiers declared in the section will not be stored in the main project file anymore, but separately in the .aim or .ams file that you selected.
To export a copy of a section to a .ams file, just highlight the section in the model editor and then, via the AIMMS Menu, select export.
To make a section available for sharing among projects, please use the following steps:
Open attribute window of the section you wish to export
Select wizard button of the source file attribute
Select Write in the menu
Select the location you want to store the .ams file
Set the filename to what you want and press Save
Importing a section¶
To import an
.ams file, please use the following steps:
Create a new section in your model that will hold the identifiers that will be imported
Select this section identifier in the model tree
In the Edit menu, select Import…
Select the .ams file that you want to import
After this, AIMMS will present you with a dialog that shows which identifiers will be imported and which ones are conflicting with already existing identifiers in your model.
When using the source file attribute of a section, you can store the contents of the section in a separate file (if you do not use the “Remove (keep subtree)…”). Please note that if you use an .ams file for the source file attribute, changes that are made to this text file with any other program (e.g. a text editor or version management system) while the AIMMS project is open will not be picked up by AIMMS! Only after you close and re-open the project, will these changes be visible in your project.
