Hello there, Quick Intro: We have an interactive CLI for a language called M used in banking and healthcare... I am working on adding readline integration as a nice to have feature. We are an open source project located over here: https://gitlab.com/YottaDB/DB/YDB.
I sent an earlier message, and I thank Chet for the reply. I am dealing with the unpleasant for anybody to handle signals. One of our signals suspends execution, completely unwinds the C stack (yes, we have lots of assembly code for that), and then reissues the prompt. An example will help: YDB>write "f<cursor>o <<< Receive SIGUSR1 Once a SIGUSR1 is received, in the background, execution is suspended, a custom function is executed, and the entire prompt code is actually processed, but the user sees absolutely nothing of that. In the example above, the cursor will stay between f and o. Our current code just sets up all the prompt data structures from a saved structure when the signal is received. Is this possible with readline()? I naively tried rl_save_state() and rl_restore_state(), but that doesn't seem to work. --Sam
