Missing process list and other oddities in Windows

[hyperlink]

This is what it looks like in Windows 7.

• braille characters are drawn with an offset
• process list is empty
• other info doesn't line up

[MrRio]

You might wanna try cygwin, I think it supports Unicode, and also should install the 'ps' tool we use for the process list.

[branneman]

And this is PowerShell on Windows 8. cmd.exe looks about the same.

[branneman]

If I use an app like Console, the braille characters do work, but still no normal lines. Those should be easy to fix, right?

[cmc19]

I dont know of a version of ps for windows. The best alternative that i know of is tasklist.

[MrRio]

Does Windows cygwin not ship with ps?

[branneman]

ps can be easily added to windows, and tools like Git actually do this. There's a ps.exe inside my C:\Program Files (x86)\Git\bin, this is an example output:

┌─bvandermeer@laptop-work C:\Users\bvandermeer\Source
└─$ ps

There's also projects like MinGW and GnuWin32, so there's multiple options for windows users to have stuff like ps.

[branneman]

On the other hand there's the command tasklist on windows, which will always work. I think that's always a better option.

[branneman]

I will build a new module to abstract away the os-specifics to get a list of currently running processes. This ought to be easy for me, since I have a windows system, and have got a lot of linux experience.

[MrRio]

Perfect :)

[branneman]

FYI: Work In Progress here: https://github.com/branneman/current-processes

Once I'll get myself a FreeBSD and Solaris VM, I can finish and npm publish. Should be soon.

[MrRio]

Nice work :+1:

Can you paste me the output of

SET >> vars.txt

I'll see if I can tackle this term issue for the boxes.

[branneman]

I think the term issue should be something that blessed should fix. Issue https://github.com/chjj/blessed/issues/28 describes this exact problem.

But here's your paste from my SET output. I censored some lines, but most of it is here:

If I run SET TERM=windows-ansi before running vtop, I do get the correct lines. Maybe the solution could be as easy as upgrading blessed? Or do what the note on Windows says, add this:

if (process.platform === 'win32') {
    var screen = blessed.screen({ term: 'windows-ansi' });
}

[matthiasg]

weird .. it doesnt even start on my machine (win 10 x64, node 5.4.1) citing: The system cannot find the path specified. not the vtop.cmd mind you, it can find that fine, but vtop.cmd is using /bin/sh.exe ? which obviously doesnt exist. reason being the bin/vtop file wanting to execute in a /bin/shinstead of in node (which would be correct for cross platform)

[tjmoore]

Likewise same problem as @matthiasg . However on Windows 10 you can install the Linux subsystem (Ubuntu bash for Windows) and just install it from there. Works perfectly, even the ncurses style formatting. Downside is you only see processes within the subsystem, not Windows processes.

[kumarharsh]

I'm not able to get this started on Windows too...

Windows 10, Creators Update

'/bin/sh' is not recognized as an internal or external command,
operable program or batch file.
