I have a shell command that I am running in a RealBasic App, and until now I've just been reading the output, but it requires user input. Is there something I could use to embed something like a terminal or a console application that could run a command, show the output, and take the input, maybe in a widget looking like a text area, like many IDEs and code editors have?
There is no pre-built control in RealStudio to accomplish this. However it's trivial to implement with a TextArea control and a Shell object set to Mode=2.
An example of this is included in the RealStudio Examples directory in your RealStudio install directory (by default on Windows, C:\Program Files\REAL Software\Real Studio\Examples\Shell\Interactive Shell.rbp.)
Could you separate the output and input, or would this not make sense for your use case?
If you could, then you could simply use a TextArea to display the console app's output, just keep appending to the TextArea's text. Then use a TextField for single line input underneath the TextArea, or whatever else makes sense for entering the params you need to send to the console app.
Then you can use a button (or catch [RETURN] key up in TextField) to grab the input and pass on to the console app.

I am working in a tool which requires the user to interact with a console and for each typed command there is a graphic representation with the result of the command. I would like to have a single JavaFX app with a TextArea serving as the console for the spring-shell app and a canvas serving as the visualization output.
How can I replace standard input / output used by spring-shell with a TextArea?
Thanks
I can get basic html text to flip 180*, but I'd like to know how to get a whole Doc in my Drive file to flip using a standalone script (so I can do it repeatedly). I'm aware I can get a doc, open the scripts editor and then use my flippin' project to flip the doc I called, but I don't know what the syntax looks like. My first flippin' success was pasting text into the .html file as simply as possible and using:
function doGet() {
return HtmlService.createHtmlOutputFromFile('Page');
getContent()
}
I just test ran it from the dialog box as a web app. But I'm interested in building this one command feature out into several different domains to get experience with the variety of possibilities available in GAS. Anyone care to tutor me? Please?!...
While willing to write ↩a as a new shortcut for the run all cells above command I could not find how to specify the return symbol in Jupyter Notebook.
Writing return-a or ↩-ain the Edit Command Mode does not work and the modifier is not specified in the help dialog.
Any idea?
Return is not a modifier so shortcut like ↩-a make little sens (pressing enter and A at the same time. ↩,a meaning Return key followed by A key make more sens, but Enter is so pervasive for many actions that it is not usable in user shortcuts. I would suggest you to open an issue on jupyter/notebook on GitHub to ask for return to be added as a convenient way to map to ↩ , though even if we do that we can't guaranty that it will work. If you are willing to try to code that yourself, have a look at keyboard.js, the mapping from enter to displaying ↩ is already done in quickhelp.js, for mac at least.
Let's take a look at one of the demos.
runExample("09_upload")
I am using the supplied file to perform some computations and to display an aggregated performance across all uploaded files. Therefore, I use something like
tryCatch(compute.smth(), error=function(e){})
so that the displayed result is not affected by the bad input. However, I'd like to indicate somehow that uploading the bad file lead to an error, notifying the user about the problem with his input. It'll be something like
tryCatch(compute.smth(), error=badFile())
where badFile() should modify some displayable output. Any ideas?
As a last resort, this is probably an option, but I'd like some native Shiny.
You can show alerts like below with the ShinySky package: https://github.com/AnalytixWare/ShinySky
You can install the package using
install.packages("devtools")#if not alrady installed
devtools::install_github("ShinySky","AnalytixWare")
Place a shinyalert(id) in the ui.R for where you want the alert to appear.
In your server.R
Make sure you have a 3 parameters funciton being passed to shinyServer e.g.shinyServer(function(input, output,session) {
use showshinyalert(id,HTMLText,session) to show the alert. Clicking on the alert will dismiss it.
See this gist for example https://gist.github.com/xiaodaigh/7707701

(1) For example, I want to set map gd g* in Qt's Fakevim like below but failed.
(2) And also I'd like to set F3 as the save command, how to do it?
(3) In Fakevim, it provides an option "Read .vimrc", but where to find the file .vimrc?
Thank you!
It doesn't look like there is a lot of documentation for FakeVim, so official sources might not exist. Most of this was obtained by experimentation.
If you want to dig deeper, I guess there's no source as official as the actual source: http://qt.gitorious.org/qt-creator/qt-creator/blobs/0809986e501415fe2c8508800b94b5b3169dc048/src/plugins/fakevim/fakevimplugin.cpp
User commands
First off, realize that in Tools>Options>FakeVim>User Command Mapping, you're only setting what your user actions will perform, not how you perform them.
By default, user command #1 is triggered by pressing Alt-V, then 1.
Alt-V, then 2, triggers user action #2, and so on.
You can change the keyboard shortcuts through the general QtCreator configuration interface, under Tools>Options>Environment>Keyboard. There is a "FakeVim" section with all the user actions listed. Select your user action of choice, press the little "erase" icon in the input field under "Shortcut", then press your desired shortcut key, which should appear in the input field.
Second, to finish a command where you would normally press enter, you should literally type in <CR> after the commands. You also need to enter in ':' to enter command mode.
So if you wanted to map the vim save command, ":w", to F3 via FakeVim, you would:
Go to Tools>Options>FakeVim>User Command Mapping.
Enter ":w<CR>" as one of the user commands (say #7).
Go to Tools>Options>Environment>Keyboard.
Find the FakeVim action "UserAction7".
Set F3 as a shortcut for it.
Now, every time you're in the editor, you should be able to click F3 and have the FakeVim :w command execute, which will save your file.
Note that there is also an option to set a shortcut for "Save" directly in the QtCreator keyboard settings, so for this particular shortcut you don't actually need to go through FakeVim.
Setting shortcuts for other vim commands should be similar. Note that you're restricted to the subset of vim commands that FakeVim implements. Refer to the source, linked above, for checking any particular command you're wondering about.
Vimrc file
On Linux this would be ~/.vimrc, a file in the user's home directory. I presume you're asking about Windows.
The best source I can find is this bug report about it being hard to use Fakevim's vimrc on Windows: https://bugreports.qt.io/browse/QTCREATORBUG-8748
Following that, the file Fakevim looks for is ".vimrc" in %USERPROFILE% (you can enter a name like that in Explorer to go to the folder). However, it's tricky to access a file with a name like that on Windows. (Thus why the real vim uses '_vimrc' on Windows -- but FakeVim apparently doesn't, at least at the moment.)
Here is a superuser page with workarounds for how to create such files on Windows: https://superuser.com/questions/64471/create-rename-a-file-folder-that-begins-with-a-dot-in-windows
