@tiev The idea with templates is that you can create file templates using the erb engine, populate them with data from the command. This is exactly what teletype is doing to setup all the files for you. In future I will add some glue code to make it obvious what is happening here and create some empty template files.
@coreynwops_gitlab Ok, if I understand you correctly, you want something that converts arbitrary objects/hashes into another format json/yaml you name it. That would be cool to have but this is not specific to terminal apps and hence won't fit into tty namespace. However, if you want to convert tabular data into different formats then I can surely see this as part of https://github.com/piotrmurach/tty-table
I dont have a real-world-issue with it right now, its more about the API and consistency of calling stuff. E.g. mysql:
TTY::Command.new.run(:mysql, *["--user", conf.user, "--password=#{conf.password}"], in: open("/tmp/stuff.sql"))
I prefer the above form over
TTY::Command.new.run("mysql --user #{conf.user} --password=#{...}") (direct string interpolation)
Now, this is a special case bacause of the mysql-command being bitchy. It does not accept
--password mypass, but requires the equal sign and no space, like --passwod=mypass. This is the case only for this option, probably because of security considerations. Because of this, I cannot use the first shown example, because cmd.run(:mysql, *["--password=#{'mypass']") will result in mysql --password\=mypass. Usually that is what you want: nicely escaped! But in rare cases like this one, I dont want it. Same is true for the following command mysql -uuser -ppass mydb -e 'SHOW TABLES'. As SHOW TABLES has a space inside, it will be escaped and not be correcty parsed by mysql.
Should I open an issue to discuss a possible API design if there is no workaround or overlooked solution?
@fwolfst I believe the command is basically the same as
system(...). If you specify one string, it gets executed using the shell. If you provide multiple arguments, they get provided to the OS level execve.
system("mysql", "-e", "SHOW TABLES") should work just fine
execve shouldn't be touching the args, they are passed directly through to the child process
I saw the tty-editor but seems it cannot do that
ok I actually get why it crashed, the content of the block should evaluate to a string (duh....) but my question stands, is there a way?
@Dwake5 you must get terminal size and draw box for the whole terminal. Tty has thay two features
@minhl337 One way I can think of doing this:
prompt = TTY::Prompt.new
prompt.ask("Date of birth (yyyy-mm-dd)?") do |q|
q.validate(/\A\d{4}-d{2}-d{2}\Z/)
q.messages[:valid?] = "Invalid date format"
q.convert :datetime
endThis will validate correct format and convert the input into DateTime for you.
@nivpgir Currently there is no way, tty-prompt was developed much earlier than tty-box and cannot be absolutely positioned inside terminal to allow it to be wrapped inside a box.
If I pause within the script, between table creation and render, and then call render myself, I get a string with what looks the table in it as the response, but nothing is actually output to the terminal. This is within a rake task.
Am I missing something obvious?
I would like to make an app like
ls or mkdir that we call without passing a command.
@matheussilvasantos I would generate a new gem with teletype and add command, so for example, you get
mkdir create and then in cli.rb use default_command :create to instruct your binary to run create command when no command is provided. It's a bit roundabout way but it should work and gives you benefits of writing tests and more.
Hello. I found a behaviour about default option for multiline input in tty-prompt and am wondering whether this is deliberate? In the spec, it states that the returned value for a multiline question with default option enabled returns an empty array. If this is deliberate, can I know what is the rationale behind this design?

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.
