👋🏼 hallo guys,
i want to write a cli dart app. which starts nano .... and at exit save the input should be parsed to a File(...) as content.
i already tried to look for something like this on the pub.dev site, but couldn't find anything. maybe i'm looking for it wrong ... ?
for example:
var output = *start nano*
var file = File(argResults!['file-name']).writeAsStringSync(output);
how can i do that?
Have a look at the 'editor' function in the dcli package.
https://onepub.dev/packages/dcli
It starts an editor and waits for it to close.

I am trying a proof of concept here:
Using Chaquopy 4.0.0 (I use python 2.7.15), I am trying to write a string to file in a specific folder (getFilesDir()) using Python, then reading in via Android.
To check whether the file was written, I am checking for the file's length (see code below).
I am expecting to get any length latger than 0 (to verify that the file indeed has been written to the specific location), but I keep getting 0.
Any help would be greatly appreciated!!
main.py:
import os.path
save_path = "/data/user/0/$packageName/files/"
name_of_file = raw_input("test")
completeName = os.path.join(save_path, name_of_file+".txt")
file1 = open(completeName, "w")
toFile = raw_input("testAsWell")
file1.write(toFile)
file1.close()
OnCreate:
if (! Python.isStarted()) {
Python.start(new AndroidPlatform(this));
File file = new File(getFilesDir(), "test.txt");
Log.e("TEST", String.valueOf(file.length()));
}```
It's not clear whether you've based your app on the console example, so I'll give an answer for both cases.
If you have based your app on the console example, then the code in onCreate will run before the code in main.py, and the file won't exist the first time you start the activity. It should exist the second time: if it still doesn't, try using the Android Studio file explorer to see what's in the files directory.
If you haven't based your app on the console example, then you'll need to execute main.py manually, like this:
Python.getInstance().getModule("main");
Also, without the input UI which the console example provides, you won't be able to read anything from stdin. So you'll need to do one of the following:
Base your app on the console example; or
Replace the raw_input calls with a hard-coded file name and content; or
Create a normal Android UI with a text box or something, and get input from the user that way.
I have a page which has a script tag. The script inside that tag is very long, but I would like to debug it. Unfortunately, I cannot scroll to the relevant place in the Console, because after a certain length the script is simply not displayed, see the attachment:
As you can see, it ends with
return !filt...
The actual function looks like this:
this.validate = function(filters) {
for (var filter in filters) {
if (!innerValidation(filters[filter].filterType, filters[filter].evaluatedValue, data[filters[filter].key])) {
return filters[filter].isOr;
}
}
return !filters[filter].isOr;
};
Question: Why does Chrome truncate my script and how could that be changed?
Note, that I know I could load it from an external file, but I am actually interested to know the cause of this behavior.
The display of the script is truncated but it still parses and runs the code correctly. You should be able to view the full code in the Sources tab under the relevant host and put breakpoints in there.
If you have a long script, it is best to make that into its own file instead. This will provide you with the best debugging experience.
The Elements panel truncates large scripts to help keep things fast and there is no way to undo this. Therefore, you would need to use some external debugging tools to try and get at this, but even then most of them work best with external script files as well.
Inline scripts should be very short if ever used. For any decent sized chunks of scripting, allocate that into its own file.
Below are the additional bullets :
I can get my "button" with following code :
$elem = $driver->find_element('//*[#id="file_uploader"]/div/div/div/div[1]/div[1]/div/span');
$driver->mouse_move_to_location(element => $elem); # xoffset => x, yoffset => y
$driver->click_ok('LEFT');
$driver->pause(3000);
But after that, I can't get anything in Opened Window which appears . How is it possible to upload a file?

Thanks in advance !
Selenium can not deal with OS dialogs. Therefore there is no way to deal with this dialog. This means you need to upload a file without opening it.
Luckily Selenium allows the user to send the filepath to the file input. This will upload the file.
In order to make it work you first need to find the input element instead of the button. It'll look something like:
<input type='file'>
Once you've found this element you can send the filepath to it like you would send any text to a textfield. I'm not sure how to do this in perl, but in Python you can achieve it like this:
element.send_keys('path/to/file')
You'll probably know yourself what the perl equivalent is.
In fact, it's more specifical. I have two ways to upload a file in my web application :
First user can use a button 'select file'.
Second you can drop directly file .
By second way, and using "upload_file" method in Selenium::Remote::Driver package as it was proposed here, it's possible. I do that :
my $fname = "D:/dev/tests/selenium/phantomjs-2.1.1-windows.zip";
my $remote_fname = $driver->upload_file( $fname );
my $element = $driver->find_element( '//*[#id="file_uploader"]/div/div/div/div[1]/div[2]/input[#class="dx-fileuploader-input"]' );
$element->send_keys( $remote_fname );
But not with my "button".
How is it possible ? I'm forwarding you additional screenshots here :

I'm trying to write a init script for the Atom editor to add a custom command to be able to reveal the currently opened editor file in the tree-view with one key combination, instead of two.
Here is an example code (which makes something different) to make clear how it generally has to look like.
atom.commands.add 'atom-editor', 'custom:cut-line', ->
editor = atom.workspace.getActiveEditor()
editor.selectLine()
editor.cutSelectedText()
The two commands I need should not be sent to the editor, but to the tree-view. Here are the two commands:
tree-view:toggle-focus
tree-view:reveal-active-file
I assume I have to do something similar as above, like getActiveTreeView or something like that. I tried to google it but it doesn't seem to be obvious. Does someone know how to do this?
It could look something like this:
atom.commands.add 'atom-editor', 'custom:show-active-file', ->
tree-view.toggle-focus()
tree-view.reveal-active-file()
You can use the atom.commands.dispatch() method to send a command when getting a hold of the object to send the commands to is hard. In your case, you can use:
atom.commands.add 'atom-editor', 'custom:show-active-file', ->
atom.commands.dispatch(atom.workspaceView.element, 'tree-view:toggle-focus')
atom.commands.dispatch(atom.workspaceView.element, 'tree-view:reveal-active-file')
Sadly, Lee's answer is not correct anymore. Within changes in the API the changed the naming of atom.workspaceView to atom.workspace.
So, if anyone gets here (sure questions and answer is a "bit" old), here's the current working script.
atom.commands.add 'atom-editor', 'custom:show-active-file', ->
atom.commands.dispatch(atom.workspace.element, 'tree-view:toggle-focus')
atom.commands.dispatch(atom.workspace.element, 'tree-view:reveal-active-file')

I often call the same commands in MongoDb command shell, for example :
db.user().find().pretty();
How would you store and call back this command ?
Ideally converting it to something like this :
db.findp( 'user' );
I believe this is NOT what your looking for, now that I read your question again: http://docs.mongodb.org/manual/applications/server-side-javascript/
Instead you are looking to modify the console in such a manner to make your life easier.
I should note, right now, that there is actually an extension which can do this sort of auto-formatting for you made by 10gen: https://github.com/TylerBrock/mongo-hacker
However if you wish to modify the files behind MongoDBs console a little more then you will need to do some manual labour.
There is a rc script in your home directory called .mongorc.js. In this file you can place any custom code you like (as #Asya mentioned) and it will actually become a command within the console.
In you rc file you could place a function like:
DB.prototype.pfind = function(col){
return this[col].find().pretty();
};
Or you could write:
DBCollection.prototype.pfind = function(){
return this.find().pretty();
};
Then you should be able to do:
db.pfind('users');
Or with the second command:
db.users.pfind();
Of course this method is for Linux, I am unsure about Windows, however, Windows should have an rc type script somewhere I believe.
