- **Add [SPDX-style](https://spdx.dev/) license attribution** to all source files. This is ongoing.

- **Header file restructuring.** The current separation of the APIs into many `include/fossil-scm/*.h` files is somewhat confusing. The initial intent was to keep my low-end development system of the time from choking on syntax highlighting on one large file, but those days are largely behind me. It may make sense to combine those into 1 public API file, 1 internal API file, and the auto-generated config file(s). (Even then, it's big enough to choke emacs' syntax highlighting on lower-end systems like Raspberry Pi SBCs.)

- **Stop using char as booleans**. This tree historically uses `char` type for booleans. Now that the tree is C99, we can switch to the `bool` type. This is ongoing.

- **f-vdiff**: port in [](fossil:3504672187af59f0) in order to be able to select the diff width based on the terminal size.

- **f-vdiff**/dibu: port the DELETE/INSERT collapsing from [](8752aca1b7187d39) into the ncurses unified diff view.

# Maybe (and Maybe Not) TODO

- **Undo** support.

- **Bring some of the configuration-related state up to date.** The infrastructure is there but the exact list of fossil-supported properties is lagging behind by several years. On the other hand, the majority of such config state is really application-specific and probably has no business being handled by this library. Some settings, e.g. `forbid-delta-manifests`, we internally honor to avoid Grief in downstream repositories. Others, such as the various globs settings, have API-level support and can be honored by the appropriate library APIs via toggles (e.g. the file-add API optionally honors the `ignore-glob` setting).
