Extract individual library versions

[Mike-Devel]

Is there a simple way to only extract the files relevant to Spirit classic/v2/x3? Unfortunately, it is not at all clear from the project structure what belongs to what.

Have you considered to use a separate repository for each of those libraries (not sure if boost rules allow this, or be desirable for your project at all - just a thought that came to my mind)?

If I recall correctly there is a tool to extract boost libraries with all their dependencies. You can take a look at this stackoverflow question: https://stackoverflow.com/questions/2150836/how-to-extract-the-boost-interprocess-library (https://stackoverflow.com/questions/2150836/how-to-extract-the-boost-interprocess-library) Hope this helps.

I probably should have been more explicit. I meant only the files for classic OR for v2 OR x3 from this repository. IIRC, bcp will not distinguish between them.

The Spirit has a very clear structure. Splitting is not a thing that is promoted or supported, but should be simple to achieve.

• Spirit X3 boost/spirit/home/x3.*
• Spirit V2 boost/spirit/home/support.*
  • Qi boost/spirit/home/qi.*
    • Shortcuts boost/spirit/include/qi.*
    • Repository boost/spirit/repository/home/qi.*
      • Shortcuts boost/spirit/repository/include/qi.*
  • Karma boost/spirit/home/karma.*
    • Shortcuts boost/spirit/include/karma.*
    • Repository boost/spirit/repository/home/karma.*
      • Shortcuts boost/spirit/repository/include/karma.*
  • Lex boost/spirit/home/lex.*
    • Shortcuts boost/spirit/include/lex.*
• Classic boost/spirit/home/classic.*

You also can list the only headers that is required with Clang echo #include "boost/spirit/home/x3.hpp" | clang -I"path/to/boost" -H -fsyntax-only -x c++ - 2>&1 | grep -oe boost/spirit/.*

x3 seems to also have some dependencies on boost/spirit/home/support/ e.g. here: https://github.com/boostorg/spirit/blob/e14eaa3057a48776371a557631422deeb0ad81de/include/boost/spirit/home/x3/char/char.hpp#L11-L14.

Thank you very much for the script that will be very helpful. Seems like GitHub has eaten some of your quotes though. Should be:

echo '#include "boost/spirit/home/x3.hpp"' | clang -I"path/to/boost" -H -fsyntax-only -x c++ - 2>&1 | grep -oe "boost/spirit/.*"

@djowel how do you look at splitting classic into its own repository? There are some precedents in boost of doing that to break dependency cycles. It will also decrease the number of dependencies people have to install if they are not needed classic (boost_thread and its subdependencies).

Good question. I think it is a good idea.

[Mike-Devel]

Would it make sense to go even one step further and separate each version (classic, v2, x3) into a separate repo? Or are v2 and x3 closely coupled?
