Hi,

Our vala packages bundle themselves via bundled bootstrap binaries.
When I asked in #vala on the irc.gnome.org, I was pointed to
https://gitlab.gnome.org/ricotz/vala-bootstrap as a possible solution.

Thanks,

Maxim

Small correction, it appears to be bootstrapped source files, i.e.
compiler-generated C code.

Looking at the vala source code, we can bootstrap the current version
from 0.39.5.8, which appears to be between release cycles – 0.39.6
already requires it, whereas 0.39.5 bootstraps from 0.25.1.  I'm not
sure how to get 0.25.1 to build from source, though.  The code in vala-
bootstrap does not appear helpful, it in fact reads exactly like Vala-
compiled Vala.

Cheers

I've now hosted my own vala-bootstrap [1], which has valacompiler.c and
gee translated to more readable C already.  I'd be happy to take in
patches or transfer it to the bootstrappable project.

Neat!  Will you send patches to use it to bootstrap our vala in Guix?

An easier route to bootstrap Vala could be the archeological approach:

Oldest commit(SVN import): 68f95ffe3aef82aac0fb7bbc65d1faab19902e3c
Last commit with only C code(except for tests written in Vala): 
c300d9c3d0af08f628b6c260bdd32f431a47e0f2

Became self-hosting(it still bootstraps with written C code under valac/): 
29a1dec53a4661779cc819ede69732c6c1118088

Removed bootstrappability(removed valac/ directory and uses Vala-generated C 
code under ccode/): 35bd6909ba2b8467ba95dfe6360e7a7e227115c8

Oldest release: VALA_0_0_1

This information should make it possible to bootstrap Vala.

Provided that we find a version of yacc that doesn't choke on the
grammar files.  Also, we got an uncertain road ahead for Valas before
0.35.1, and then vala 0.39.6 did a dirty bump in which they rely on a
practically unreleased version.

So yes, the archeological approach could work, but I wouldn't
necessarily count on it being "easy".

Cheers
