One of the intended uses of the =specific= tag is to include code that will be exported only to latex into the preamble.

It would be nice to be able to include multiline content into the tag. Currently, this is not possible.

Here is a usecase:


I define several macros in the preamble that I use consistently in TeXmacs in a given paper (recurring operators/constructions). My workflow would require the following:

1) Ask Texmacs not to include any of the macro definitions into the latex file and just use the macros as is.
2) Ask Texmacs to include handwritten macro definitions into the latex file.

1 & 2 require to surround every TeXmacs =assign= command in the preamble by a =<specific|texmacs|???>= tag.

2 requires writing TeX code and surrounding each line by the =<specific|latex|???>= tag

2alt) write all latex code into a separate file e.g. =paper.sty= kept in the same directory + add one directive:
=<specific|latex|\usepackage{paper}>=

Note that 2alt still requires surrounding every texmacs assign statement with a =<specific|texmacs|???>= tag.


I know that defining a texmacs style is a more proper way, however

- it is more technically involved

- Texmacs has bugs when dealing with per-project styles that are included locally, rather than including globally installed ones. (on Windows)

The ability to surround a large block with =<specific|texmacs|???>= would be a fantastic intermediate solution.
