While testing some of my new environments I made a mistake like this:
...
begindocument
...
beginA
...
endA
...
beginB
...
endA
...
enddocument
LaTeX complained that B did not end when document ended. And it talks about the line where enddocument is, and the line where beginB was, but it did not talk about the mismatching endA (the location of the actual error).
Why can't LaTeX detect such? I know that newenvironment actually defines two commands, one for beginning and one for ending, but isn't it possible to detect the case where something is to be ended that never had begun?
Update 1:
The example I had given was (to my best knowledge) the essence of the problem, and I contructed it in the head as the original file has thousands of lines and many figures, etc. (too much to present here, and also written by a TeX analphabet, so you will tear your hair out to see my struggles...). But people do not believe what I wrote. So I made a small test file from my big file, showing the problem:
Here's the essential part of the input:
begingfxTableCap[p]lrCaptionlabel2%
gfxCap0.4Platzhalter.pdfCaption 2A
&
gfxCap0.4Platzhalter.pdfCaption 2B
endgfxTableCapLab
Causing this output (truncated to the essence):
This is pdfTeX, Version 3.14159265-2.6-1.40.18 (TeX Live 2017/TeX Live for SUSE Linux) (preloaded format=pdflatex)

So it does not say "unexpected endgfxTableCapLab.
In case it's special for the environments I had defined, here's the mess:

While testing some of my new environments I made a mistake like this:
...
begindocument
...
beginA
...
endA
...
beginB
...
endA
...
enddocument
LaTeX complained that B did not end when document ended. And it talks about the line where enddocument is, and the line where beginB was, but it did not talk about the mismatching endA (the location of the actual error).
Why can't LaTeX detect such? I know that newenvironment actually defines two commands, one for beginning and one for ending, but isn't it possible to detect the case where something is to be ended that never had begun?
Update 1:
The example I had given was (to my best knowledge) the essence of the problem, and I contructed it in the head as the original file has thousands of lines and many figures, etc. (too much to present here, and also written by a TeX analphabet, so you will tear your hair out to see my struggles...). But people do not believe what I wrote. So I made a small test file from my big file, showing the problem:
Here's the essential part of the input:
begingfxTableCap[p]lrCaptionlabel2%
gfxCap0.4Platzhalter.pdfCaption 2A
&
gfxCap0.4Platzhalter.pdfCaption 2B
endgfxTableCapLab
Causing this output (truncated to the essence):
This is pdfTeX, Version 3.14159265-2.6-1.40.18 (TeX Live 2017/TeX Live for SUSE Linux) (preloaded format=pdflatex)

So it does not say "unexpected endgfxTableCapLab.
In case it's special for the environments I had defined, here's the mess:

LaTeX detects it. Exactly when the document ended andBwas never finished. How is it supposed to detect it earlier? It does not have a human brain.

It is not that people don't (want to) believe what you write. It's the fact that in some (many?) situations the issue you describe does not occur (as demonstrated in the answer), so your situation must be special and people need to see code that actually reproduces the problem to be able to help.

Note for example that if I complete the code at the beginning of the question to a working example withdocumentclassarticle newenvironmentAAA newenvironmentBBB begindocument beginA endA beginB endA enddocumentTeX says! LaTeX Error: beginB on input line 11 ended by endA.on l.13 and thus gives a good error message. But if I saynewenvironmentBbeginAendAinstead, I get! LaTeX Error: beginB on input line 11 ended by enddocument.. This is what you have in your second example code.

the new code produces a different error! Package pdftex.def Error: File"""Platzhalter".pdf' not found: using draft setting` really the idea is you make a minimal example that produces the error that you are asking about, but I'll fix that this time.

@U.Windl I already fixed your example not to require a figure which was not necessary to demonstrate the error that you were asking about. If you have a question that does need a figure, you can useexample-imagewhich is in tex distributions for such tests but here I simply deleted theincludegraphics

While testing some of my new environments I made a mistake like this:
...
begindocument
...
beginA
...
endA
...
beginB
...
endA
...
enddocument
LaTeX complained that B did not end when document ended. And it talks about the line where enddocument is, and the line where beginB was, but it did not talk about the mismatching endA (the location of the actual error).
Why can't LaTeX detect such? I know that newenvironment actually defines two commands, one for beginning and one for ending, but isn't it possible to detect the case where something is to be ended that never had begun?
Update 1:
The example I had given was (to my best knowledge) the essence of the problem, and I contructed it in the head as the original file has thousands of lines and many figures, etc. (too much to present here, and also written by a TeX analphabet, so you will tear your hair out to see my struggles...). But people do not believe what I wrote. So I made a small test file from my big file, showing the problem:
Here's the essential part of the input:
begingfxTableCap[p]lrCaptionlabel2%
gfxCap0.4Platzhalter.pdfCaption 2A
&
gfxCap0.4Platzhalter.pdfCaption 2B
endgfxTableCapLab
Causing this output (truncated to the essence):
This is pdfTeX, Version 3.14159265-2.6-1.40.18 (TeX Live 2017/TeX Live for SUSE Linux) (preloaded format=pdflatex)

So it does not say "unexpected endgfxTableCapLab.
In case it's special for the environments I had defined, here's the mess:

errors environments

While testing some of my new environments I made a mistake like this:
...
begindocument
...
beginA
...
endA
...
beginB
...
endA
...
enddocument
LaTeX complained that B did not end when document ended. And it talks about the line where enddocument is, and the line where beginB was, but it did not talk about the mismatching endA (the location of the actual error).
Why can't LaTeX detect such? I know that newenvironment actually defines two commands, one for beginning and one for ending, but isn't it possible to detect the case where something is to be ended that never had begun?
Update 1:
The example I had given was (to my best knowledge) the essence of the problem, and I contructed it in the head as the original file has thousands of lines and many figures, etc. (too much to present here, and also written by a TeX analphabet, so you will tear your hair out to see my struggles...). But people do not believe what I wrote. So I made a small test file from my big file, showing the problem:
Here's the essential part of the input:
begingfxTableCap[p]lrCaptionlabel2%
gfxCap0.4Platzhalter.pdfCaption 2A
&
gfxCap0.4Platzhalter.pdfCaption 2B
endgfxTableCapLab
Causing this output (truncated to the essence):
This is pdfTeX, Version 3.14159265-2.6-1.40.18 (TeX Live 2017/TeX Live for SUSE Linux) (preloaded format=pdflatex)

So it does not say "unexpected endgfxTableCapLab.
In case it's special for the environments I had defined, here's the mess:

It is not that people don't (want to) believe what you write. It's the fact that in some (many?) situations the issue you describe does not occur (as demonstrated in the answer), so your situation must be special and people need to see code that actually reproduces the problem to be able to help.

Note for example that if I complete the code at the beginning of the question to a working example withdocumentclassarticle newenvironmentAAA newenvironmentBBB begindocument beginA endA beginB endA enddocumentTeX says! LaTeX Error: beginB on input line 11 ended by endA.on l.13 and thus gives a good error message. But if I saynewenvironmentBbeginAendAinstead, I get! LaTeX Error: beginB on input line 11 ended by enddocument.. This is what you have in your second example code.

the new code produces a different error! Package pdftex.def Error: File"""Platzhalter".pdf' not found: using draft setting` really the idea is you make a minimal example that produces the error that you are asking about, but I'll fix that this time.

@U.Windl I already fixed your example not to require a figure which was not necessary to demonstrate the error that you were asking about. If you have a question that does need a figure, you can useexample-imagewhich is in tex distributions for such tests but here I simply deleted theincludegraphics

Please always post actual test documents not untestable fragments. In general latex would detect that error at the
endA
but there are cases when it can not, for example if B was verbatim then by definition all processing is disabled until endB is seen, in which case that error would only be detected at end of file.
so
documentclassarticle
begindocument
beginempty
endempty
beginquad
endempty
enddocument
produces an error message on line 11
! LaTeX Error: beginquad on input line 9 ended by endempty.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.

looking at the specific example provided, note that tex is a macro expansion system not a compiler it never parses the full document in advance.
so starting from
begingfxTableCap[p]lrCaptionlabel2%
endgfxTableCapLab
enddocument
after the first few expansions of gfxTableCap you have
begingfxTableCapLabplrCaption%
endgfxTableCapLab
enddocument
so the explicit endgfxTableCapLab in your document closed the inner environment, but the outer gfxTableCap is never closed and that can not be detected until the closing of a containing group which is enddocument here.

Probably more a comment than an answer. As for the test document: I typed it from memory as I don't have the document here, and the document actually is way to large to present here. I'm trying to extract a test case (hopefully) to demonstrate the problem. What I can say for now is that my environment messes with floats.

It is not that people don't (want to) believe what you write. It's the fact that in some (many?) situations the issue you describe does not occur (as demonstrated in the answer), so your situation must be special and people need to see code that actually reproduces the problem to be able to help.

Note for example that if I complete the code at the beginning of the question to a working example with
documentclassarticle newenvironmentAAA newenvironmentBBB begindocument beginA endA beginB endA enddocumentTeX says! LaTeX Error: beginB on input line 11 ended by endA.on l.13 and thus gives a good error message. But if I saynewenvironmentBbeginAendAinstead, I get! LaTeX Error: beginB on input line 11 ended by enddocument.. This is what you have in your second example code.– moewe

the new code produces a different error
! Package pdftex.def Error: File"""Platzhalter".pdf' not found: using draft setting` really the idea is you make a minimal example that produces the error that you are asking about, but I'll fix that this time.– David Carlisle

@U.Windl I already fixed your example not to require a figure which was not necessary to demonstrate the error that you were asking about. If you have a question that does need a figure, you can use
example-imagewhich is in tex distributions for such tests but here I simply deleted theincludegraphics– David Carlisle
