Setting Minimum API Level
Each release of the T-Nspire™ software includes API support for a specific set
of Lua scripting features. Setting the minimum API level for a script lets you
specify a minimum set of features that you require for your script.
If a user tries to run the script on a system that does not meet the script's
minimum API level, a message notifies the user and prevents the script from
running.
To Set the Minimum API Level for a Script:
1. Determine the minimum level that you want your script to require.
- Setting the level too low for the script's feature set can result in a script
error on older software.
- Setting the level too high can result in the script refusing to start on
older software that supports the feature set.
2. On the Script Editor File menu, select Set Minimum API Level.
3. In the dialog box, type the minimum level using the format major.minor.
For example, you might type 2.3.
This API level or higher will be required for running the script.
Saving Script Applications
Clicking Set Script resets (updates) a script application in a TI-Nspire™ or
PublishView™ document. However, the script and script application are not
saved until you save the document. If you close the document or close the
TI-Nspire™ software without saving, work on the script is lost.
To ensure the script application is saved after all work is complete, follow these
steps.
1. From the Script Editor window, click Set Script to reset (update) the script
application in the document.
2. From an open document, click File > Save Document to save changes to
the TI-Nspire™ or PublishView™ document.
Note: To ensure work is backed up, set the script and save the document
frequently.
