描述问题

If the user uses a non-built-in style and then opens the pdf-tm after exporting the pdf-tm, the style will be displayed incorrectly.

I suggest that you should fix this bug first and then start to port the code from Mogan to GNU TeXmacs.

I would like to help with the TeXmacs port of the project. What is the current status? I start to badly need this feature working in TeXmacs. :) Fixing for non-standard style file could be quite complex, as it means importing arbitrarily nested styles and packages. Moreover these style files could depend on scheme scripts which would not be importable/usable from the pdf-tm. So it is not clear what a correct fix is. In some sense it is not a problem of pdf-tm but a lacking feature of TeXmacs: make documents independent of the surrounding environment. The clean solution so far should be to detect the problem and warn the user that the tm-pdf file still depends on outside content which has to be present in order for the file to render correctly.

The only annoying bug is that it only works for PDF 1.4, if one switched the PDF version to 1.5/1.6/1.7, it will fail to attach the tm document to PDF without any warning or error.

What is the problem? where the program fails and how I can test the problem? I've adapted the code for TeXmacs and I'm preparing a PR here: https://github.com/texmacs/texmacs/tree/wip_pdftm

I've also modified a bit the embedding code, since the version in Mogan does not embed the bibliographic data in the original document. (both attachments and auxiliary elements of the document)

What is the problem?

In Edit->Preferences->Convert->Pdf->Pdf version number, set it to 1.5, 1.6 or 1.7, the exported PDF does not contain the texmacs document.
