AMPL IDE currently does not support the features you mentioned. We will add them to our feature request list.
Some users gave very positive feedback of the unofficial AMPL extension for VSCode
Perhaps you could give it a try?
The procedure will be:
- install VSCode in your machine.
- click on the Manage symbol, go to extensions, search for AMPL and install the extension.
- click on the Manage symbol, select Settings > extensions > ampl and specify the path to the AMPL executable, so that you can use AMPL in the VSCode terminal.
Auto-complete, bracket matching and other features will be available.
Hope this helps!
Best regards,
Nicolau
