Bracketed Paste Mode is not enabled on Windows #53763
Description
Windows Terminal now supports "bracketed paste mode" when in VT (Virtual Terminal) Mode. This will allow Windows users to paste into the Julia REPL with text beginning with "julia>", which will then be removed from the input. This feature already exists for Linux and macOS users. (It probably works for the one FreeBSD user too).
Here is where the work was done to enable this in Windows:
https://devblogs.microsoft.com/commandline/windows-terminal-preview-1-18-release/
microsoft/terminal#15155
To enable virtual terminal input, use SetConsoleMode with ENABLE_VIRTUAL_TERMINAL_INPUT.
Here is a demonstrating, starting with some setup.
# From REPL.Terminals.enable_bracketed_paste
function enable_bracketed_paste()
write(stdout, "\x1b[?2004h")
end
# Similar to REPL.LineEdit._console_mode()
function get_input_console_mode()
hInput = ccall(:GetStdHandle, stdcall, Ptr{Cvoid}, (UInt32,), -10 % UInt32) # STD_INPUT_HANDLE
dwMode = Ref{UInt32}(0)
ccall(:GetConsoleMode, stdcall, Int32, (Ref{Cvoid}, Ref{UInt32}), hInput, dwMode)
return dwMode[]
end
function enable_virtual_terminal_input()
hInput = ccall(:GetStdHandle, stdcall, Ptr{Cvoid}, (UInt32,), -10 % UInt32)
dwMode = get_input_console_mode()
ENABLE_VIRTUAL_TERMINAL_INPUT = 0x200
ccall(:SetConsoleMode, stdcall, Int32, (Ptr{Cvoid}, UInt32), hInput, dwMode | ENABLE_VIRTUAL_TERMINAL_INPUT)
endHere's how it can be used.
julia> get_input_console_mode() # Virtual terminal input is not enabled by default on Windows
0x00000007
julia> 5+5 # copied the line before the comment

julia> readline() # pasted the line

"julia> 5+5"
julia> begin

@info "" get_input_console_mode()
readline() # pasted the same line
end
