input

问题 In Bash the only way to get a (user) input seems to be to use the read method, which pauses the rest of the script. Is there any way to receive a command line input (ending with the enter key) without pausing the script. From what I've seen there may be a way to do it with $1 ..? 回答1: read -t0 can be used to probe for input if your process is structured as a loop #!/bin/bash a='\|/-' spin() { sleep 0.3 a="${a:1}${a:0:1}" echo -n $'\e'7$'\r'"${a:1:1}"$'\e'8 } echo 'try these /|\- , dbpq , |)>)

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 9 years ago . Can anyone provide me a direct and easy way (ofcourse with codes and other necessary libraries to be included for right execution) to input data from excel file to C++? Actually, I need to input a huge amount of

问题 I'm trying to get user input and allowing them to only input a whole number which is also positive.

CHARACTER NOT ACCEPTED!!\n"); else if (First <= 0) printf("Error! First must be a positive value!\n"); else if (Second <= 0) printf("Error Second must be a positive value!\n

问题 Basically, I have an angular application, and I would like to have (change) only be triggered after a few seconds of nothing happening. Therefore instead of sending requests every time a letter is written in an input field, only after writing a letter and nothing happening for a few seconds, then the request would be sent. 回答1: You may use rxjs debounceTime piped to the valueChanges observable of the reactive FormControl as in the example at https://stackblitz.com/edit/angular-debounce-form

问题 I need to display certain inputs when an option from the dropdown menu is selected. The dropdown menu consists of three options, Blood Pressure, Weight and Temperature. When the user selects an option, the input fields relating to that option need to be visible and the rest hidden. For example when the user selects Blood Pressure, the systolic and diastolic input fields need to be visible, the temperature and weight fields need to be hidden. <Form.Item label="Vital"> {getFieldDecorator("vital

问题 I am making a simple 2d game in the terminal, and I have been wondering how I could get stdin without having to return. So, instead of the user having to press w\n (\n for return), they would just press 'w' and it would go forwards. scanf, gets, and getchar cannot do this, but I have seen it be done before in programs such as Vi. How would I achieve this? 回答1: You need to set your terminal to non-canonical mode. You can use functions like tcsetattr, and tcgetattr to set and get terminal
