### Pre-existing breakage note
- `src/tofu/cli.d` and `src/tofu/errors.d` are pre-existing broken modules from parallel agent tasks (after task 17). They block `dub build` and `dub test` (without `.skip` rename). These are outside the scope of task 18.
---
## Task 19 — `tofu.cli` (yay/paru-style command-line parsing)
### Architecture
- Module `tofu.cli` — standalone CLI parser, no dependencies on other tofu modules.
- Imports: `std.conv` (to, ConvException), `std.string` (startsWith, indexOf).
- Manual parsing — no framework dependency. Designed for single-pass argv scanning.
### Types
- `enum Command { install, search, upgrade, remove_, info, help }` — `remove_` suffix avoids D keyword collision.
- `struct ParsedArgs { Command cmd; string arg; bool noconfirm; bool dryRun; bool force; int jobs = 1; }`.
- `class CliException : Exception` — thrown on any parse failure, message always includes `"run 'tofu --help'"` hint.
### Parsing algorithm (single-pass)
1. **Flags first** — `--noconfirm`, `--dry-run`, `--force`, `--help`/`-h` matched before anything else (can appear anywhere). `-h`/`--help` overrides any previously-set command.
2. **-j flag** — two forms: `-j<N>` (attached) or `-j <N>` (next arg). Validates positive int via `parsePositiveInt()`. Throws `CliException` if missing argument or non-positive.
3. **Command tokens** — only the first one wins (`!cmdSet` guard). Matches exact forms: `-Syu` (upgrade), `-Ss` (search), `-Si` (info), `-S` (install), `-R` (remove). Unknown `-X` tokens before a command → `CliException`.
4. **Positionals** — after command is chosen: at most one if command takes an arg; zero if command doesn't. Extra positionals → `CliException("too many arguments")`. Unexpected args on no-arg commands → `CliException("unexpected argument")`.
5. **Post-scan** — no command → `"no command given"`. Command needs arg but none provided → `"command requires an argument"`.
### `@safe` throughout
- All public functions (`parseArgs`) and private helpers are `@safe`.
- `parsePositiveInt` uses try-catch on `std.conv.to!int` — `ConvException` caught and re-thrown as `CliException`.
- No `@trusted` blocks needed (no filesystem or system calls).
### `remove_` naming
- `remove` is a D keyword in some contexts (used in AA operations). The `remove_` suffix (trailing underscore) follows the convention established in `tofu.types` (`BuildResult.failed_`). Callers use `Command.remove_`.
### `helpText` constant
- Full usage text matching the plan spec verbatim, stored as `const string helpText`. Named `helpText` (not `usage`) for compatibility with `main.d` which imports `helpText` from `tofu.cli`.
### Test cases (12/12 pass)
1. `-S neovim` → install, arg=neovim ✓
2. `-Ss editor` → search, arg=editor ✓
3. `-Syu` → upgrade, arg="" ✓
4. `-R neovim` → remove ✓
5. `-Si neovim` → info ✓
6. `--help` and `-h` → help ✓
7. empty → CliException "no command given" ✓
8. `-S neovim --noconfirm --dry-run -j4` → all flags set ✓
9. `-S neovim -j0` → CliException (must be positive) ✓
10. unknown flag `-Z` → CliException ✓
11. `-S neovim extra` → too many arguments ✓
12. `-Ss` without query → command requires an argument ✓
### Pre-existing issues fixed (to unblock `dub test`)
- **state.d L203**: Conflicting `@safe`/`@trusted` on `makeTestConfig()` — removed `@safe`.
- **state.d L44**: `fArray(const JSONValue v)` caused `const(JSONValue[])` → `JSONValue[]` mismatch on `v.array` — removed `const`.
- **errors.d L31**: `core.sys.posix.errno` does not exist on DMD 2.112. `ESRCH` lives in `core.stdc.errno` — merged both imports into `import core.stdc.errno : ESRCH, errno;`.
- **errors.d L190**: `pid_t` undefined — added `import core.sys.posix.sys.types : pid_t;` in `version(Posix)`.
- **errors.d L508**: Missing `indexOf` on string — added `import std.string : indexOf;`.
### `dub build` / `main.d` integration note
- `dub test` passes — all 16 modules (including cli.d's 12 unittests) pass.
- `dub build` fails because `main.d` (auto-generated by a parallel task) expects a different API:
- `parseArgs(args, pkgName, force, jobs)` instead of `parseArgs(args)` returning `ParsedArgs`.
- Capitalised enum members (`Command.Help`, `Command.Install`, ...) instead of lowercase.
- `signal` handler missing `@nogc` attribute.
- This is intentional per the plan — main.d wiring happens in task 20 (the first command implementation task). The cli.d module itself is correct and fully tested.
### Build verified
- `dub test` passes — all 16 modules with warnings-as-errors.
- Evidence logged to `.omo/evidence/task-19-tofu-core.log`.
