Jan Mas Rovira 2d36a65324 Make compile targets a subcommand instead of a flag (#2700) ... # Changes The main goal of this pr is to remove the `--target` flag for `juvix compile` and use subcommands instead. The targets that are relevant to normal users are found in `juvix compile --help`. Targets that are relevant only to developers are found in `juvix dev compile --help`. Below I list some of the changes in more detail. ## Compile targets for user-facing languages - `juvix compile native` - `juvix compile wasi`. I wasn't sure how to call this: `wasm`, `wasm32-wasi`, etc. In the end I thought `wasi` was short and accurate, but we can change it. - `juvix compile vampir` - `juvix compile anoma` - `juvix compile cairo` ## *New* compile targets for internal languages See `juvix dev compile --help`. 1. `dev compile core` has the same behaviour as `dev core from-concrete`. The `dev core from-concrete` is redundant at the moment. 2. `dev compile tree` compiles to Tree and prints the InfoTable to the output file wihout any additional checks. 3. `dev compile reg` compiles to Reg and prints the InfoTable to the output file wihout any additional checks. 4. `dev compile asm` compiles to Asm and prints the InfoTable to the output file wihout any additional checks. 5. 4. `dev compile casm` compiles to Asm and prints the Result to the output file wihout any additional checks. TODO: should the Result be printed or something else? At the moment the Result lacks a pretty instance. 6. ## Optional input file 1. The input file for commands that expect a .juvix file as input is now optional. If the argument is ommited, he main file given in the package.yaml will be used. This applies to the following commands: 1. `juvix compile [native|wasi|geb|vampir|anoma|cairo]` 8. `juvix dev compile [core|reg|tree|casm|asm]` 1. `juvix html` 3. `juvix markdown`. 4. `juvix dev internal [typecheck|pretty]`. 5. `juvix dev [parse|scope]` 7. `juvix compile [native|wasi|geb|vampir|anoma|cairo]` 9. note that `juvix format` has not changed its behaviour. ## Refactor some C-like compiler flags Both `juvix compile native` and `juvix compile wasi` support `--only-c` (`-C`), `--only-preprocess` (`-E`), `--only-assemble` (`-S`). I propose to deviate from the `gcc` style and instead use a flag with a single argument: - `--cstage [source|preprocess|assembly|exec(default)]`. I'm open to suggestions. For now, I've kept the legacy flags but marked them as deprecated in the help message. ## Remove code duplication I've tried to reduce code duplication. This is sometimes in tension with code readability so I've tried to find a good balance. I've tried to make it so we don't have to jump to many different files to understand what a single command is doing. I'm sure there is still room for improvement. ## Other refactors I've implemented other small refactors that I considered improved the quality of the code. ## TODO/Future work We should refactor commands (under `compile dev`) which still use `module Commands.Extra.Compile` and remove it.		2024-04-09 13:29:07 +02:00
