“Wheel Of Fortune” game CHALLENGE!!!1!

[zapshe]

Console animations have simply never impressed me, so I really don't feel accomplished in doing them.

Any program that I'm serious about and needs a user interface I'll create a GUI for.

Hell, I made a copy of the dino game on chrome, which could have been on console, but I used a whole GUI for it lmao

Does it have to be C++? I think this is just the perfect use case for https://charm.sh/

Here's my attempt at console style wordle (very crude ATM -- might polish a bit later):

Sorry to be slow on the promised update. I forgot what a nightmare parsing input is for xterm, and I want to give you all something better than my usual hacks. (I know, I’ve been saying I’ll make a console how-to for ages.)

Maybe I’ll cut it down to just getting non-function keys from the keyboard and leave out the UTF-8/function/extended keys and mouse input...

Tell me what you want.

[edit]
Does WSL2 matter to y’all?
Because you could just get input from the linux event subsystem too...
But that doesn’t properly exist on WSL2.



OK, the REAL question is:

Anyone still using Windows Console in Windows < 10 (8, 7, Vista, XP, ...)?

Going forward, I’m going to assume Windows 10.

[Geckoo]

Is there a deadline before submitting?

[seeplus]

Anyone still using Windows Console in Windows < 10 (8, 7, Vista, XP, ...)?

Yes - Windows 7!

PS. Isn't WSL a Windows virus that needs to be removed? :) :)

[Duthomhas]

@Geckoo
The only deadline is a locked-n-archived topic.

[deleted account xyzzy]

AFAIK as long as there are recent replies to the topic it stays open.

I don't know what the idle time is needed to lock the topic, it's at least several months from what I've seen.

Anyone still using Windows Console in Windows < 10 (8, 7, Vista, XP, ...)?

I use it all the time. I have a number of work related batch files, and I use cygwin pathed into the console for grep and a few other unixy tools. I often delete files from the console, its faster (the windows delete likes to do a bunch of slow thinking about it operations up front and then prints what its doing which also slows it way down). I like the bulk copy (xcopy and the new one I keep forgetting) operations. I compile the little programs here in the forums in g++ (cygwin again) if I need to do so. I redirect to and from files a bit as well. I have any number of subst invocations to make fake drives for various reasons.

I think windows finally lets you do everything in the GUI that you can do in the console, but far less efficient. My oldest install is win 8, though. I had a 7 until fairly recently.

[Duthomhas]

I’ve always done almost everything from the terminal. Way back from CP/M through Windows 95, XP, 7, and now 10, and all the random Linux variations I played with. Oh, and Sun OS at University, but I dunno if that counts here.

Clicking through a gazillion menus (folders) to do anything at all is truly obnoxious. I can fire up my terminal prompt and have everything at my fingertips.

As an aside, I can’t stand PowerShell. It took the terminal idea and goobered it to be as painful as possible.

The key to using the terminal is managing your PATH. The next is to keep utilities handy. I set my terminal startup to automatically run C:\Users\Michael\bin\prompt.bat, which is actually pretty simple:

@echo off
cls
path C:\Users\Michael\bin;%PATH%
chcp 65001 > nul

if "%ConEmuDir%"=="" (
  prompt $E[33;1m$P$G$E[90m 
)

set DIRCMD=/ogn

:: Macro Aliases

doskey apath=for %%F in ($1) do @path %%~fF;%%PATH%%
doskey mpath=for %%A in ("%%PATH:;=";"%%") do @if not "%%~A"=="" @echo   %%~A
doskey rpath=for %%F in ($1) do @for /F "usebackq delims=" %%M in (`echo set "PATH=%%PATH:%%~fF=%%"`) do @%%M

doskey deltree=rd/s/q $*
doskey dira=dir/a $*
doskey dird=dir/a-hd $*
doskey mcd=@md $* $T @cd $*

doskey 7z="C:\Program Files (x86)\7-Zip\7z.exe" $*
doskey npp="C:\Program Files (x86)\Notepad++\Notepad++" $*

... and so on.

`doskey` is the Windows version of the *nix `alias`. It works a little differently, though, so make sure to type help doskey before you use it. (And it is a much easier read than searching through man bash to read up on alias.)

Then I populate my C:\Users\Michael\bin directory with a bunch of useful little batch files. For example, I can look at all my macros (aliases) with:

  C:\Users\Michael\bin\macros.bat

::if 0 {
  @echo off
  tclsh "%~f0" %*
  goto :EOF
}

set f [open "|doskey /macros"]
set s [read $f]
if {[catch {close $f} err]} {
  puts $err
  exit
}

set lines []
set max 0
foreach line [lsort -dictionary [split $s \n]] {
  if {$line eq {}} continue
  lassign [split $line "="] alias command
  lappend lines [list $alias $command]
  set max [expr {max($max, [string length $alias])}]
}

foreach alias_command $lines {
  lassign $alias_command alias command
  puts "[format %${max}s $alias] = $command"
}

C:\Users\Michael> macros
     7z = "C:\Program Files (x86)\7-Zip\7z.exe" $*
  apath = for %F in ($1) do @path %~fF;%PATH%
 astyle = C:\m\bin\AStyle\bin\astyle.exe -A1 -s2 $*
blender = title blender 3.0 $T "C:\Program Files\Blender Foundation\Blender 3.0\blender.exe" $*
    npp = "C:\Program Files (x86)\Notepad++\Notepad++" $*
...

In order to keep the path clean when programming, I’ll actually nest invocations of cmd.exe. So, for example, I can type:

C:\Users\Michael> msvc x64

and C:\Users\Michael\bin\msvc.bat will start a new shell in the same terminal (cmd /k ...) and find and run vsvarsall.bat for an AMD-64 toolchain. (msvc.bat is actually rather lengthy, being both DOS batch script and being smart enough to complain if it has already been invoked and being able to find and invoke the correct vsvarsall.bat script — I have multiple versions of VS installed.)

That way when I am done I can get back to a “clean” prompt by simply typing exit. Here’s a useful script to report how many times the command shell has been nested for a particular terminal:

  C:\Users\Michael\bin\levels.bat

::if 0 {
  @echo off
  :: 
  :: Report the number of cmd.exe processes running in this Windows Console window
  :: (You can 'exit' n-1 times before this Windows Console closes.)
  ::
  set source=%~f0
  if exist %source%.bat set source=%source%.bat
  tclsh %source% %*
  goto :EOF
}

set pss [exec {*}[auto_execok wmic] process get processid,parentprocessid,executablepath]
foreach ps [split $pss \n] {
  lassign [lreverse [string map {\\ /} $ps]] pid ppid exename
  set PARENTS($pid) $ppid
  set EXES($pid) [file tail $exename]
}

set p [pid]
set n 0
while {$p in [array names PARENTS]} {
  if {$EXES($PARENTS($p)) ne "cmd.exe"} break
  incr n
  set p $PARENTS($p)
}

puts $n

You may have noticed that I tend to use tclsh (Tcl shell) for a lot of useful stuff when DOS batch is either insufficient or just too obnoxious and clumsy. It doesn’t really matter which shell/interpreter you recur to — VisualBasicSript is already installed on Windows systems and you could use that — Python is also a useful alternative. Heck, you could even make PowerShell scripts if that floats your boat. You could even compile little C++ programs to do stuff. The point is to have useful tools.

All this can be easily duplicated in a Linux prompt. I have WSL2 up and running (complete with an X Server so I can run graphical Linux programs from the Ubuntu prompt as well). I add aliases to my ~/.bashrc (or ~/.profile, if needed) to make switching between the two easy and convenient.

For example, I use Notepad++ regularly. Since it is a Windows program (and because notepadqq is currently garbage, sorry), I add it to my list of aliases.

  ~/.bashrc snippet

...
alias dir='ls -CF --color'
alias dira='ls -A'
alias npp='/mnt/c/Program\ Files\ \(x86\)/Notepad\+\+/Notepad\+\+.exe'
...

Now, whether I am on Windows or Linux, I can simply type:

    npp somefile.cpp

to begin editing somefile.cpp.


One interesting trick is to automagically add a utility to the path when it is first used. For example:

  C:\Users\Michael\bin\python.bat

@echo off
path C:\Python37\Scripts;C:\Python37;%PATH%
python.exe %*

Now I don’t have to care whether Python is already in the path or not. I just type python quux.py and quux.py runs properly, every time.

This works because the python.bat is initially the only thing found in the PATH, but after executing it, it is now listed after the actual python.exe executable in the PATH, so it never gets called by mistake.


Once you get everything set up, open a terminal and type mpath and look at all the junk in there. A lot of it can be removed. For example, I don’t need C:\gtkmm64\bin sitting in there. (I should have properly installed any programs using GTK!) Copy and save the list somewhere before the next step:

Click on Start (or the little hourglass on Windows 10) and type “environment variables” to get a suggestion to edit the system environment variables. (Where this actually is differs on Windows versions, so use the finder to find it.)

Be careful how aggressively you cull stuff from the list. In general, do not remove stuff from the global environment variables — especially anything in any subdirectory of C:\Windows! But feel free to remove anything you want from the local user’s (your) environment variables. If something you want stops working, you can add it back. (You did copy and save your original list, right?)

A lot of programs just add themselves to the path when they install, even when they don’t need to. Sometimes you will find stuff listed multiple times. And you will occasionally find something weird, like multiple semicolons. Feel free to fix all that, until mpath gives you a short, pretty list of essential items, with your bin directory listed right at the top.

[Duthomhas]

The idea is to cull the PATH down to only those items currently needed, and restore it to that state when you are done needing anything extra.

This is the very same principle you should apply in Linux. *nixen tend to do most of that for you, so it is rare to have to care there.

On Windows, though, it might make all the difference. For example, if you open your prompt right now and type g++, exactly which GCC are you invoking? If you’ve installed Perl, you might get that one. Or TDM, that one. Or worse, parts of both.

Keep your PATH clean.

That’s the key.

[edit]
I’m really confused about how the Report button gets used by some people. George P’s commentary seemed right on and useful.

And, honestly, as it’s my topic, it would seem to me that, unless someone is posting spam or violent or vulgar or otherwise anti-social stuff, I ought to be the only one with my finger over what belongs in this thread or not...

I never considered simply setting up your terminal and basic PATH control (something I learned from Unix) to be esoteric... I wonder what most people’s experience is?

My reported comment about the time frame for when a thread goes into archive status really was accurate, if a bit lean on details.

[deleted account xyzzy]

There is an indication of what the no archive/archive time frame is, look at the Jobs section.

A post from August 24 is locked, but a post from September 9 can have replies.

Not a definitive answer, X number of days without a reply, though.

[Duthomhas]

Hurray!

My power supply went **pop** about a week ago. Finally got a new one installed. (I contracted COVID at about the same time — a couple of days before, so it is only recently I have been able to go buy a new PS and install it.)

It was kind of... shocking... when the thing went out (loud bang and all). No actual flames, but the smell was frightening.

Glad nothing else got fried. (The PS is supposed to protect the PC when it goes poof, so chance was low of anything getting past it, but you never really know until you boot back up...)

(I’m OK on COVID too.)
