cd3 / gsc Goto Github PK

gsc's cpu usage can get high. Need to figure out how to make it wait for user input while idle. Currently we are using a select/poll loop.

In auto mode, the script is ran and user input is ignored. But since the terminal is placed into raw mode, signals are not send to gsc, so the user can't kill a running gsc session with Ctrl-C.

The user should at least be able to kill gsc, but it might be useful to accept some command in auto mode so the user could pause for example. This would probably require making the user input handler async. It currently blocks.

When gsc is ran without an input parameter or argument boost gives a conversion error. A fix would be to print out the proper syntax of the command and where to find further help.

script parser sends all files to the session. need to process script lines.

add support for turning stdout on/off

If gsc does not run the script and exit as normal, the child processes can stay alive. For example, if something causes a segfault in the main proc, the child proc are not killed.:

currently have a hack in place that ignores multi-char key presses. need to implement this correctly.

this would be a good project to test the conan package manager on.

If these keys are pressed during a demo, the demo freezes and has to be terminated. The monitor shows that gsc is still receiving key pressed through.

A quick look at show_key shows that all of these keys actually send 4 characters. Not sure if that is the problem. Perhaps a key combination is being sent to the shell that turns off stdout?

if there are blank lines in the script file, they get sent to the shell as soon as they are encountered. they should wait for the user to press return.

If bash is used, the input lines are not echoed to the screen. zsh works fine.

It would be nice to be able to run a session in an ncurses window so we could display some extra information while a session is running.

For example:

• a window that shows what keys were "pressed", even if they are not visible.
• rewind support. the ability to go back in the session script and have the display output window rewind as well.
• display current input mode (insert, throughput, command, etc)

The --wait-chars option allows a list of characters that gsc should pause on, for example if you want gsc to wait for user input on all tabs. It would be useful to change this on the fly. If you have a command that produces a prompt asking for user input (for example "Are you sure? [Y/n]"), sometimes these prompts only read one char so the prompt exits as soon as the y char is sent. In this case, it would be nice to temporarily make gsc pause on y so it will show before the prompt disappears.

It would be useful to write the commands that actually get ran to a file. This would allow a script to be updated/corrected while running.

need to configure terminal size when starting a session.

also, terminal settings are not being restored correctly after a session finishes.
