LaTeX 2e environment that “knows” the name of surrounding environment
5
I'd like to have a LaTeX 2e-environment which when occurring inside another environment "knows" the name of the surrounding environment.
Is this possible?
I know that @currenvir provides the name of the current environment.
I seek some sort of @surroundenvirwhich provides the name of the surrounding environment.
E.g.
documentclass{article}
makeatletter
newenvironment{FOO}{message{@currenvir-begin: Surrounding environment's name is @surroundenvir}}%
{message{@currenvir-end: Surrounding environment's name is @surroundenvir}}
newenvironment{BAR}{message{@currenvir-begin: Surrounding environment's name is @surroundenvir}}%
{message{@currenvir-end: Surrounding environment's name is @surroundenvir}}
newenvironment{FOOBAR}{message{@currenvir-begin: Surrounding environment's name is @surroundenvir}}%
{message{@currenvir-end: Surrounding environment's name is @surroundenvir}}
makeatother
begin{document}
begin{FOO}
end{FOO}
begin{BAR}
end{BAR}
begin{FOOBAR}
end{FOOBAR}
begin{FOO}
begin{BAR}
begin{FOOBAR}
end{FOOBAR}
end{BAR}
end{FOO}
end{document}
shall deliver console output:
FOO-begin: Surrounding environment's name is document
FOO-end: Surrounding environment's name is document
BAR-begin: Surrounding environment's name is document
BAR-end: Surrounding environment's name is document
FOOBAR-begin: Surrounding environment's name is document
FOOBAR-end: Surrounding environment's name is document
FOO-begin: Surrounding environment's name is document
BAR-begin: Surrounding environment's name is FOO
FOOBAR-begin: Surrounding environment's name is BAR
FOOBAR-end: Surrounding environment's name is BAR
BAR-end: Surrounding environment's name is FOO
FOO-end: Surrounding environment's name is document

Environments are usually called using a begin-end clause. You can patch begin (using etoolbox) to store the value of @currenvir before it is updated:
documentclass{article}
usepackage{etoolbox}
makeatletter
% patchcmd{<cmd>}{<search>}{<replace>}{<success>}{<failure>}
patchcmd{begin}{begingroup}{begingrouplet@surroundenvir@currenvir}{}{}
newenvironment{FOO}{message{@currenvir-begin: Surrounding environment's name is @surroundenvir}}%
{message{@currenvir-end: Surrounding environment's name is @surroundenvir}}
newenvironment{BAR}{message{@currenvir-begin: Surrounding environment's name is @surroundenvir}}%
{message{@currenvir-end: Surrounding environment's name is @surroundenvir}}
newenvironment{FOOBAR}{message{@currenvir-begin: Surrounding environment's name is @surroundenvir}}%
{message{@currenvir-end: Surrounding environment's name is @surroundenvir}}
makeatother
begin{document}
begin{FOO}
end{FOO}
begin{BAR}
end{BAR}
begin{FOOBAR}
end{FOOBAR}
begin{FOO}
begin{BAR}
begin{FOOBAR}
end{FOOBAR}
end{BAR}
end{FOO}
end{document}
This yields in the .log:
FOO-begin: Surrounding environment's name is document
FOO-end: Surrounding environment's name is document
BAR-begin: Surrounding environment's name is document
BAR-end: Surrounding environment's name is document
FOOBAR-begin: Surrounding environment's name is document
FOOBAR-end: Surrounding environment's name is document
FOO-begin: Surrounding environment's name is document
BAR-begin: Surrounding environment's name is FOO
FOOBAR-begin: Surrounding environment's name is BAR
FOOBAR-end: Surrounding environment's name is BAR
BAR-end: Surrounding environment's name is FOO
FOO-end: Surrounding environment's name is document
Note that @currenvir defaults to document, set inside the LaTeX2e kernel.
