How I can intercept keystroke in Rust without any libraries?
For example: press W - print: "Press key 'W'".
without any libraries?
There's nothing in the standard library to do this, no.

I am writing a small game program in c++, which requires user to press some keys from keyboard. The problem with 'cin>>' or cin.get() is that it requires user to press enter to read data into memory. So, please help me to read key strokes with out pressing enter key. I work on Linux.
maybe you can use ncurses library?
By default the terminal is buffered and is in "cooked mode" where individual key presses are not sent to the application immediately.
You might be able to use something like GNU readline for input, or you could use ncurses for input and output, or if you just want to receive every key as it's pressed you could put the terminal into raw mode and do everything manually using the cfmakeraw function.
My cygwin terminal (known as Mintty) can't work, when I minimize it to the windows taskbar, and restore it, and it will receive the Ctrl-C signal, but i didn't touch any key.
This is wierd. when a long time command is running, i swith it to see wether is finishe, then it is interputed my Ctrl -C. I refresh intall it several times. it's still there.
This situation can also happened when i select some text on the terminal.
Thanks
Some translator software have the "Hyper Translate" function, which will copy texts selected then tries to translate it, the way how it copy strings is to simulate a Ctrl-C from keyboard. When using cygwin or some ssh/telnet terminal tools (e.g. SecureCRT, putty, NX Client..) and the Ctrl-C is not set as the hotkey for copy action, and you tries to select a block of texts, trouble comes.
I guess the one who asking this question is also a Chinese like me. Then, the famous software which will bring this trouble is "Youdao Dictionary".
Disabling the "Hyper Translate / HuaCiFanYi" function of the "Youdao Dictionary" is a remedy.
As Leif Zhang mentioned, if you are using Lingoes or other dictionary you should uncheck the option Translate Selected Text as the following image.
I'm trying to use xdebug with vim on linux. I follow the instructions to install xdebug and after that I can see the information about xdebug if I call phpinfo() from a file inside the apache server.
After open a file in vim, it is supposed that when I press F5 it should show something like "waiting for a new connection on port 9000 for 10 seconds...", but it doesn't show anything..
Any idea?
I would recommend you look at a new vim debugger plugin, called vdebug: https://github.com/joonty/vdebug -- it is actively developed and seems very capable.
I had the same sort of problem, it turned out that my terminal emulator was capturing the keypress and not sending it to vim (I think). Remapping the functions to different keys solved the problem.
It could actually be his/her keyboard. If the keyboard has mult-media functions as well as F1-F12 on them... then there is, usually a "F-Lock" key next to the row of function keys that will turn on/off the function key behavior. Really annoying, IMHO, for the new keyboards sold these days.... and rarely does the keyboard have a light to indicate the ulterior operation of said function keys.
I say this cuz, that is exactly what happened to me just now.
I've played around with processEnter, on command, and on anyKey with textEntry to no avail. I've been looking through the massive amount of documentation for wx-core, but I don't see anything that'll help. I'm using wxhaskell 0.13.2.1 on Windows 8.
You need to use wxTE_PROCESS_ENTER style to have a chance of capturing the Enter key in a wxTextCtrl. If you don't use it, this key is used for activating the default dialog button -- or beeping, under Windows, if there is no such button.
To scratch a personal itch, I'm writing something like a cross between a character map and an on-screen keyboard. When the user selects a character, I'd like to insert it into another application, specifically, the application that would next receive focus if my application were closed. Is there any way to do this? Right now, I work around it by just putting the character into the clipboard and terminating, leaving the user to hit paste in the other application, but usage would be far more streamlined if I could just insert the text programmatically.
I'm doing this in GTK and expect to run it only on Linux. But cross-platform solutions are also appreciated, and if GTK can't do it but some other toolkit can, I'll gladly switch.
This sounds like you should use libwnck, which is a GTK-related library that lets you manipulate windows on the desktop. The documentation is a little sparse, but the function wnck_screen_get_previously_active_window() seems promising.
From a WnckWindow you can get an X window ID, and perhaps from there you can use the X libraries to send a paste message (or even send it a "Ctrl-V" keypress event), perhaps with XSendEvent().
Very good question, by the way. I wish I could answer it more knowledgeably.
