Question

What is the most effective way to dynamically incorporate external input into a SlimerJS script?

Could use some assistance with SlimerJS. My current program requires intermittent input from stdin to proceed with the next task.

The code below functions effectively when using PhantomJS+CasperJS for reading external input, but encounters difficulties with SlimerJS+CasperJS.

some code ...

var nextLink = system.stdin.readLine();

some code ...

Any suggestions on resolving this issue?

javascript casperjs slimerjs

Answer №1

It is clear that this feature is not supported, as seen in the feature request on GitHub and the absence of the stdin property in the official documentation.

There are primarily two potential solutions to this issue. Both involve creating a secondary program in a language of your choice, which can also be a PhantomJS script.

One workaround involves continuously checking a predefined file for input when necessary in the CasperJS script. When the point is reached where input is needed, the second program would be executed. This secondary program could be something simple like:
```
echo my text > predefinedFile.txt
```
or it could be more complex. The polling functions in CasperJS would resemble this:
```
function poll(){
    var content = fs.read(predefinedFile).trim();
    if (!content) {
        this.wait(1000, poll);
    } else {
        // perform desired actions
    }
}
//....
casper.then(poll);
```
Another option is utilizing the webserver module, which allows sending messages to SlimerJS while running as a CasperJS script. The second program would need to send actual requests.
