TC 0.7.0 introduces a new `TaskData` type that maps to Taskwarrior's
`Task` type more cleanly. It also introduces the idea of gathering lists
of operations and "committing" them to a replica.
A consequence of this change is that TaskChampion no longer
automatically maintains dependency information, so Taskwarrior must do
so, with its `TDB2::dependency_sync` method. This method does a very
similar thing to what TaskChampion had been doing, so this is a shift of
responsibility but not a major performance difference.
Cxx is .. not great. It is missing a lot of useful things that make a
general-purpose bridge impractical:
- no support for trait objects
- no support for `Option<T>` (https://github.com/dtolnay/cxx/issues/87)
- no support for `Vec<Box<..>>`
As a result, some creativity is required in writing the bridge, for
example returning a `Vec<OptionTaskData>` from `all_task_data` to allow
individual `TaskData` values to be "taken" from the vector.
That said, Cxx is the current state-of-the-art, and does a good job of
ensuring memory safety, at the cost of some slightly awkward APIs.
Subsequent work can remove the "TDB2" layer and allow commands and other
parts of Taskwarrior to interface directly with the `Replica`.
* move taskchampion-lib to src/tc/lib, remove the rest
* update references to taskchampion
* Use a top-level Cargo.toml so everything is consistent
* apply comments from ryneeverett
* Recommend LSP's in development docs
Per conversation in #3338.
There are already a lot of documented compile options so I think we're
better off suggesting that everybody create a compile_commands.json
whether or not they're using an LSP because it doesn't cost much.
While I was at it it seemed reasonable to mention rust LSP too. Now that
rls is deprecated I'm not sure there is any competitor to rust-analyzer
worth mentioning.
* Export compile commands by default.
Thanks to @felixschurk for the idea and telling me how to do it.
It took me a minute to figure out that this places the
compile_commands.json in the build directory rather than the root of the
project. But clangd still finds it there and that's a better place for
it anyway.
* update build instructions
Usage of "modern" CMake syntax and using specific out of source build.
Further add example on how to build in parallel, build a specific target
and how to change the compiler.
This closes#3236.
* move doc/misc to top level, add READMEs
* Move docs -> doc/devel
This also consolidates the _three_ documents describing (differently)
how to build Taskwarrior into a signle document.
