            xmonad-contrib Prompt: Execute terminal prompt in a particular workspace?
            Asked 2022-Mar-06 at 12:20

            I recently decided to build XMonad from source via Stack to make a custom configuration. Let me preface by saying I do not have a ton of experience with Haskell. My OS is Linux - Arch.


            I am attempting to make use of the XMonad.Prompt package from xmonad-contrib in order to launch some applications. (

            Currently, one prompt I am using is XMonad.Prompt.Man, which launches the man program with a provided argument in the default terminal (the terminal I default to is Alacritty). (docs: (src:

            What actually is the type of C `char **argv` on Windows
            Asked 2022-Jan-27 at 20:25

            From reading docs in either MSDN or the n1256 committee draft, I was under the impression that a char would always be exactly CHAR_BIT bits as defined in . If CHAR_BIT is set to 8, then a byte is 8 bits long, and so is a char.

            Test code

            Given the following C code:



            Answered 2022-Jan-27 at 18:14

            From your code and the output on your system, it appears that:

            • type char has indeed 8 bits. Its size is 1 by definition. char **argv is a pointer to an array of pointers to C strings, null terminated arrays of char (8-bit bytes).
            • the char type is signed for your compiler configuration, hence the output 0xFFFFFFE7 and 0xFFFFFFE0 for values beyond 127. char values are passed as int to printf, which interprets the value as unsigned for the %X conversion. The behavior is technically undefined, but in practice negative values are offset by 232 when used as unsigned. You can configure gcc to make the char type unsigned by default with -funsigned-char, a safer choice that is also more consistent with the C library behavior.
            • the 2 non ASCII characters çà are encoded as single bytes E7 and E0, which correspond to Microsoft's proprietary encoding, their code page Windows-1252, not UTF-8 as you assume.

            The situation is ultimately confusing: the command line argument is passed to the program encoded with the Windows-1252 code page, but the terminal uses the old MS/DOS code page 437 for compatibility with historic stuff. Hence your program outputs the bytes it receives as command line arguments, but the terminal shows the corresponding characters from CP437, namely τ and α.

            Microsoft made historic decisions regarding the encoding of non ASCII characters that seem obsolete by today's standards, it is a shame they seem stuck with cumbersome choices other vendors have steered away from for good reasons. Programming in C in this environment is a rough road.

            UTF-8 was invented in September of 1992 by Unix team leaders Kenneth Thomson and Rob Pike. They implemented it in plan-9 overnight as it had a number of interesting properties for compatibility with the C language character strings. Microsoft had already invested millions in their own system and ignored this simpler approach, which has become ubiquitous on the web today.

            Despite the fact that emsdk is installed, following current (as at 8 Jan '22) documentation will not result in working examples. Build would be failed.

            In order to build it on Ubuntu with make --version GNU Make 4.2.1 you need to provide -e option to pass environment variables to make

            Then, after build is finished -- start python http server in examples directory and navigate to it in browser: python3 -m http.server 9999 open localhost:9999 and open desired example.



            Download Only Pre-Compiled Binaries of Rust Crates

            Answered 2021-Dec-15 at 10:51

            Since crates can be compiled with or without certain features which result in different code, there isn't any mechanism to up- or download pre-compiled crates. On top of that, the list of supported targets is very long which would make it very likely that the platform you're on doesn't have pre-compiled binaries.

            Finally, there'd need to be additional mechanisms to sign the code and verify that the pre-compiled code matches the source code.

            So all in all there are several obstacles that render implementing this impractical.



            Vim/NeoVim script how to check the terminal emulator
            Asked 2021-Dec-10 at 03:01

            I have two terminals installed on my machine one is ubuntu's default terminal and the other one is alacritty. want to check from which terminal does the vim is opened from. because I can get the alacritty work with the airline so if It is the case i will not use let g:airline_powerline_fonts = 1 and set this variable to zero. How can it be done?



            Answered 2021-Dec-10 at 03:01

            The alacritty terminal emulator usually goes with the $TERM variable set to alacritty (instead of xterm or xterm-256color or a variant.)

            So assuming that's your configuration (you might be getting the incorrect $TERM setting, particularly if you're connecting to a remote box through SSH, or using a multiplexer such as tmux or screen), you can use that in your vimrc to check whether you're running in Alacritty.

            You can check that from the shell:

            How to open multiple instances of Alacritty on macOS?
            Asked 2021-Sep-03 at 09:47

            macOS 11.4 , Alacritty 0.8.0 installed from homebrew 3.2.5 , although this should not matter because the question is mostly related to macOS UI.

            What I want to do is something equivalent to's right click on icon > New Window sort of thing; Alacritty does not support windows.

            On Linux, I'm used to launching new instance of alacritty with background option in dmenu.

            On a mac, what would a similar action look like ?
