Hover, go to definition, completion (after a dot too: fields, methods, a module's names, an enum's variants,
array/text/map methods), signature help, the outline and errors while typing -- everything the C++ one did,
and the same tests/lsp_test.py passes against it.
It doesn't type-check by itself: for every change it runs finch index on the editor's text (--overlay says
which file the text stands in for) and reads what the compiler learned about every name, which is also what
the compiler's own error messages are made of. Half-typed code keeps using the last version that compiled.
src/docs.fch is the one description of the built-ins that hover and completion share.
tests/run.sh runs the LSP test too. 107 passed.
boot/ is src/ now. The C++ compiler and CMake are gone from this branch (they are on before-bootstrap).
bootstrap/build.sh builds the compiler from bootstrap/<system>.ll -- the compiler's own LLVM IR -- then builds
it with itself and checks the two come out identical. bootstrap/build.sh seed writes the seed anew.
The driver is complete: the runtime is compiled once and kept in ~/.cache/finch; a program's own C files,
.o and .a files and frameworks link along; a linker failure is read and answered with link "lib" or the
library that is missing. The old tests/fail diagnostics are all in again (a missing import, a str compared with
null, 'write just the library's name', a map key that is a float, non-ASCII names, ...).
tests/run.sh is the one test runner: programs, refusals, -g builds and the shared library. 106 passed.
