Some holiday animations (from Vt100.net)

[miskox]

Here https://www.vt100.net/dec/animation/ you can see some .txt files that you can

type *.txt

and see some animation. Some might work some will not display correctly (they are for original DEC Video Terminals).

All .txt files are included in the .zip.

The Windows Terminal is able to handle those escape sequences pretty well

But I'm afraid my machine is way too fast and I can't see any animation.

I suspect some vt100 sequences are (actually) not supported by the console, but this fast hack might help:

Code: Select all

@echo off
setlocal enableExtensions enableDelayedExpansion

set "xmas2.speed=800"
for %%a in (*.txt) do (
	cls
	call :play "%%~a" !%%~na.speed!
	pause
)
goto :eof
call :play file [skip] [speed]


:play
setlocal
set "file=%~1"
set /a "delay=1000-%~2+0"
for /f "tokens=1* delims=:" %%a in ('findstr /n "^" "%file%"') do (
	for /l %%w in (1, 1, %delay%) do rem:
	echo(%%b
)
endlocal
goto :eof

@penpen: thanks. This works very well. Though I see some 'undefined' characters on my Win10.

Yes, original DEC Video Terminals were not that fast.

Cute, thanks for sharing

I have a question for @penpen!

Why add 0 to this?

Code: Select all

set /a "delay=1000-%~2+0"

I was inspecting your code, but I am curious if I am missing something here?

I'm guessing it's to prevent syntax errors if %2 isn't provided
