Platformio-atom-ide-terminal: Disappearing cursor with `alias cls='printf "\033c"' in ~/.bashrc`

[twifty]

• [x ] I have reset Atom to defaults prior to submitting report.
• [ ] I have not reset Atom to defaults prior to submitting report.

Description

The terminal cursor disappears when entering the \033c character.

I have defined a bash alias in my ~/bashrc file as alias cls='printf "\033c"'. When I enter the command in ide-terminal, the screen is cleared correctly, but the blinking cursor disappears. The terminal however, continues to accept input and the cursor returns after executing the next command.

I am aware of the reset command, but this causes a noticable delay.

Steps to reproduce

1. Add alias cls='printf "\033c"' to ~/.bashrc
2. run reset in ide-terminal, to reload the above file
3. run cls in ide-terminal

Expected behavior:
A blinking cursor

Actual behavior:
A missing cursor

Reproduces how often:
100%

Hi @twifty and thanks or this report.

Your alias is clearing the screen completely which is meant to do that. Could you try to use \033[H\033[J instead of \033c just in case.

What we really need is #426 term.js is wildly buggy and not maintained, so need to be replaced in order to provide better compatibility with modern terminals across OS's.

\033[H\033[J only clears the visible screen, exactly the same as the clear command. It doesn't clear the scrollback buffer. Scrolling up will reveal the history.

I use the terminal to run makefiles, so I need to quickly scroll to the output start in order to see the first compiler error. I'll continue to use \033c for now, which clears everything. The presence of a cursor is not that important.

Next time you are working on this part of the code, would you add an option to not scroll to end of output.

This project is community driven so its up to users to submit fixes and features.

Then you will have to put up with the issue until such time anyone who can fix the issue is also annoyed enough because of it and will just submit a PR. Who know when that will be,

We recently had a couple of contributions that closed old tickets, so who knows what will happen and when.

Thanks for understanding and thanks for filling in all issue template details.

Community driven? Well, when I get the time I'll look into fixing the issue.

@twifty Yes, the project owner is minimally involved just merging and doing releases as they dont use the plugin anymore read #543 for further information. So its up to us. I deal with node-pty-prebuild-multiarch and the issue tracker + testing of PRs.

Best would be to fork really but definitely need some support from other community users who are proficient at coffescript and can replace old abandoned dependencies like term.js and fix bugs etc.
