9 Interactive mode

Interactive mode is entered by executing the command asy with no file arguments. Each line must be a complete Asymptote statement; however, it is not necessary to terminate each line with a semicolon.

The following special commands are supported only in interactive mode and must be entered immediately after the prompt:

help

view the manual

reset

reset Asymptote to its initial state, except that a prior call to scroll (see scroll) and any changes to the setting outname are respected.

input FILE

resets the environment and does an erase(); include FILE. If the file name FILE contains nonalphanumeric characters, enclose it with quotation marks. For convenience, a trailing semi-colon followed by optional Asymptote commands may be entered on the same line.

quit

exit interactive mode (abbreviated as q; exit is a synonym). A history of the most recent 1000 (can be changed with the historylines command-line option) previous commands will be retained in the file .asy/history in the user's home directory (unless the command line option -localhistory was specified, in which case the history will be stored in the file .asy_history in the current directory).

Typing ctrl-C interrupts the execution of Asymptote code and returns control to the interactive prompt.

Interactive mode is implemented with the GNU readline library. To customize the key bindings, see: http://cnswww.cns.cwru.edu/php/chet/readline/readline.html
