`-dev-` was in every Emacs symbol this client owns and meant nothing to anyone
typing one: the daemon is `flan dev` at a shell, but from inside Emacs there is
no other kind of connection to distinguish it from. `M-x flan-dev` is now
`M-x flan`, `flan-dev-quit` is `flan-quit`, the private prefix `flan-dev--` is
`flan--`, and every defcustom follows — ninety-odd symbols, with the two files
renamed to emacs/flan.el and emacs/test-flan.el so the file names say the same
thing as the symbols in them.
No aliases. Renaming a defcustom breaks a config that names it and there is no
way around that; the repo has no precedent for softening one, and an alias left
behind is what keeps a rename from finishing. MANUAL.md says the old names are
gone and how to fix a config, which is the whole of the migration path.
Three strings are not symbols and keep their spelling: `.flan-dev.sock`, which
bin/main.ml writes and which a renamed variable searching for a renamed file
would simply never find; and the two buffer names `*flan-dev*` and ` *flan-dev*`,
which name the `flan dev` subcommand's own output rather than anything in elisp.
`flan dev` with a space is the CLI and is untouched everywhere.
The entry point also stops asking a question it already has the answer to. From
a buffer visiting a .flan file it starts that file; from anywhere else it reads
one from the minibuffer as before; `C-u` reads one either way, which is how you
start a second program without leaving the first. The current buffer is still
the only source of the default — the bug where a previous project won over the
buffer you were in was fixed by removing `flan--file` from that position, and
nothing here puts it back.
Four checks on the `interactive' form, evaluated on its own rather than by
calling the command, because calling it would build and launch a program and
the question is only which file the form arrives at and whether it had to ask.
A fifth asserts that nothing answers to the old names. test/test_emacs.ml loads
the test file by path and test/test_session.ml names the client file in a
comment, so the rename reaches those two lines; nothing else outside emacs/ and
the docs moved. Verified by byte-compiling every file
clean and by `dune test` and `@page`.
