Public bug reported:
Severity: minor, feature request
Steps to reproduce:
- apt install lua-check
- luacheck -v
Seen:
- lua-check depends on lua5.1, which forces system-wide change of `lua` to
`lua5.1`
- even after using `update-alternatives` to revert system back to using
lua5.3, luacheck -v reports "Luacheck: 0.21.1 \ Lua: Lua 5.1"
- Luacheck version 0.21.1 was 2017-09-10, two and a half years after Lua5.3
became the current version.
Expected:
- lua-check depends on lua-any (is it possible? is it feasible?)
Other info:
- luacheck must force the lua version to use, because lua(5.1|5.2|5.3)
searches only versioned paths for libraries -- if the luacheck libraries are in
the "5.1" paths, then the "5.3" interpreter won't see them.
Workaround: after installing package lua-check
- update-alternatives --install /usr/bin/lua lua-interpreter /usr/bin/lua5.3
130 --slave /usr/share/man/man1/lua.1.gz lua-manual
/usr/share/man/man1/lua5.3.1.gz
- update-alternatives --install /usr/bin/luac lua-compiler /usr/bin/luac5.3
130 --slave /usr/share/man/man1/luac.1.gz lua-compiler-manual
/usr/share/man/man1/luac5.3.1.gz
- mkdir -p /usr/local/share/lua/5.3
- ln -s /usr/share/lua/5.1/luacheck /usr/local/share/lua/5.3/luacheck
- perl -pi -e 's/env lua5.1/env lua5.3/' /usr/bin/luacheck
I acknowledge that this is not a "bug" per se; I don't know how else to
make a change request.
