"Missing SETLOCAL" when initializing Visual Studio Command Prompt.

[FreezerBurnt]

I'm using:

TCC 27.00.18 x64 Windows 10 [Version 10.0.19042.746]

And just recently installed Microsoft Visual Studio Community 2019, but TCC has some trouble running the command prompt initialization scripts. When running:

"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars32.bat"

I get:

**********************************************************************
** Visual Studio 2019 Developer Command Prompt v16.8.3

Missing SETLOCAL
[vcvarsall.bat] Environment initialized for: 'x86'

Digging into the setup scripts (which are quite extensive):

267 @REM Choose FrameworkDir32 or FrameworkDir64 depending on the preferred bitness.
268 setlocal EnableDelayedExpansion
269 set __DOTNET_FrameworkDir=!FrameworkDir%__DOTNET_PREFERRED_BITNESS%!

When debugging, the "Cancel" seems to come from line 268, and the error message comes from the "endlocal" that should have matched the "setlocal".

Why would I be getting a "Cancel" on a perfectly valid setlocal call?

I have no problem running that script.

Can you confirm that it's actually getting to the same line in dotnet.bat?

The initialization system is quite complicated. I can run just:

 C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\Tools\vsdevcmd\core\dotnet.bat

And get the same problem:

I put a comment just before that line (it's 267 here).

@REM Choose FrameworkDir32 or FrameworkDir64 depending on the preferred bitness.
echo at line 268
setlocal EnableDelayedExpansion

And ...

Okay, so it's probably a configuration thing. I just did a little experiment with a CMD file called setit.cmd:

setlocal ENABLEEXTENSIONS

Literally, just that. If I open a brand new TCC prompt, I get the "CANCEL". If I run it a second time, it's doesn't complain.

d:\tmp>setit.cmd
setlocal ENABLEEXTENSIONS

Cancel batch job D:\tmp\setit.cmd ? (Y/N/A) : A

d:\tmp>setit.cmd
setlocal ENABLEEXTENSIONS

d:\tmp>

Okay, I'm narrowing it down to the LOCAL and GLOBAL lists:

This causes the error:

And this doesn't:

 

[FreezerBurnt]

Yup. Found it.

Both "Functions" and "Aliases" must have one or the other checked. If neither are checked, SETLOCAL fails.

The same does not seem to be true for "History" and "Directory History".

Thanks for helping me nail this down @vefatica !!

I have a work around (honestly I'm not sure HOW I want the lists set and don't quite understand the meaning yet) and I think this should be a bug in TCC 27.

 

[vefatica]

These settings are OK (for this problem).

But they cause this to happen. I issue FUNCTION or ALIAS and get the SET command!

 

[FreezerBurnt]

Neat! And down the rabbit hole we go!

In general, I suggest you don't use TCC for scripts written for CMD.
There's too many caveats to have it working stable enough for consistent results.
