Hey! Does tty-prompt or tty-table play well with Curses? I ask because I couldn't find a way to refresh the screen if the content of a table or prompt changes. Would I be able to run tty-prompt or tty-table within a curses window and call Curses.refresh to get content to update?
@JohnConfidence TTY components don't use curses so that they can work on all platforms. Can you mix the two? I think you can but you will have to test yourself. If you wish to refresh the terminal window, you can use ANSI codes, for example, tty-cursor has clear_screen code. I hope this helps.
Any advice on how to make them play nice together?
Essentially, I want to show a progressbar above a prompt asking the user for input.
Or below, doesn't really matter.
Adding a
\n to the format string seems to have done the trick.
TTY::ProgressBar.new("progress [:bar]\n")
Side note,
render seems like it might be good to have as public api.
Hey everybody. I wonder if someone has any tip on how to do this: I would like to have TTY::Prompt return a value from a keypress event. Something like this:
prompt = TTY::Prompt.new
prompt.on :keypress do |event|
if event.key.name == :page_up
prompt.return 'four' # <= I want something like this
end
end
response = prompt.select "Select", %w[one two three]
puts "response: #{response}"I have spent the last two hours digging in the Prompt and Reader code trying to figure it out, until I admitted defeat and realized Piotr's code is way above my paygrade....
Hi everyone. I am working on a shell and I have trouble with TUI applications such as man, less, vim... I am using TTY::Command to run these commands in a PTY but it seems the input, the output, probably both are not wired correctly. Even the following code does not display things correctly (let alone input).
runner = TTY::Command.new pty: true, output: some_logger
runner.run 'vim'Are these applications supposed to be supported (am not sure if it's ncurses specific or related to termcaps)? If not, is it planned? Am I doing it wrong?
Thank you in advance :)
@Docteur-Lalla Running editor command in a child process is problematic for many reasons, including the fact that the process never finishes. Try running Ruby's
%x[vim] as a test. As an alternative, you can try tty-editor .
I guess a
min option to go with max could also work: min: 1 would ensure at least one option is selected - I can see that doesn't exist yet, though I'm not certain on the required side
When using
teletype to create a project, it creates a templates folder within lib/PROJECT. What is this meant for?
Hi @piotrmurach , thanks for the great code! I am having an issue, though, with tty::reader through a gserver socket. I start the reader with: rio = TTY::Reader.new(input: sio, output: sio) and I read lines with readline = rio.read_line("\r#{serverIdentifier}:>") ... What happens is when a user telnets to the server, each time they type a character, the prompt and their input is tabbed 8 spaces right. I love the previous command retrieval, and if I could get this glitch straightened out, I would be ecstatic! Do you have suggestions for me to try? Many thanks.
@anbayanyay_twitter This issue is not specific to TTY::Reader. This is to do with cooked vs raw terminal mode. Even if you use Ruby's
getc method you will get similar behaviour. Had a similar issue recently to do with TTY::Prompt behaviour (see piotrmurach/tty-prompt#137). Glad you managed to figure this out!
@b1tt0 I can assure you that TTY::Cursor works fine. Please make sure that you print cursor content to the terminal (read https://github.com/piotrmurach/tty-cursor#1-usage)
@keilmillerjr_gitlab Usage of a browser requires some sort of HTTP server on that side, it's quite cumbersome, but still possible, may be there are open source implementations of that out there already. I don't know your circumstances, but perhaps the easiest way of running a terminal app remotely is SSH
I overwrote a command description from "desc A" to "desc B" but it did not work. Am I doing wrong...?

@narutaro The
teletype isn't yet that smart to figure this out, unfortunately. When you come across things that could be improved or have suggestions please post them on the project issues tracker or even better submit a pull request. At the moment I'm updating all tty components and working on the tty itself to provide a bit smoother experience in v0.11.0.
Thank you for the wonderful tty-prompt and tty-screen gems. I just built these TUIs with them: https://github.com/AndyObtiva/rake-tui / https://github.com/AndyObtiva/rvm-tui
Hi @piotrmurach , I have question about tty-option. In https://github.com/piotrmurach/tty-option#2510-validate say Will internally cause an exception TTY::Option::InvalidArgument that will make params invalid. but I execute the same first example and dont get a exception
Hi @inyerade, one of the 'features', as explained in the readme docs, is that "Parsing doesn't raise errors by default and collects issues to allow for better user experience." The sentence that you cited "Will internally cause an exception TTY::Option::InvalidArgument that will make params invalid. " means that inside the TTY::Option the specific error is raised that makes the
params invalid but no actual errors are raised. I would suggest reading parse method section and params section. I wrote the Readme to document all the APIs and usage but please free to submit PR if something is missing or not clear enough. I'm keen to make sure the docs are complete and easy to use.
help needed: for some reason, I "gem install tty" but don't get "teletype" as a new command.

@JeffreyArtworks Unfortunately, this is not an issue related to
tty gem. I verified by installing v0.10.0 that the teletype executable works as expected. I'd potentially look into reinstalling Ruby version that you're using. However, this is an issue for yourself to figure out why your system fails to find Ruby installed executables.
