From d3ecf3781db4c2e2a3fa52e0958b7d6f0d9c7e55 Mon Sep 17 00:00:00 2001 From: Leynos Date: Tue, 7 Apr 2026 21:36:07 +0000 Subject: [PATCH 01/25] docs(users-guide): add advanced usage chapter with workflows and examples Introduce Section 12 'Advanced Usage' to the user guide, providing a cohesive narrative on the `clean`, `graph`, and `manifest` subcommands, configuration layering, and JSON diagnostics. This chapter offers intermediate users worked examples and ties together existing documentation in a single place to enable power-user workflows.

Extend user documentation with advanced usage chapter + +This ExecPlan (execution plan) is a living document. The sections +`Constraints`, `Tolerances`, `Risks`, `Progress`, `Surprises & Discoveries`, +`Decision Log`, and `Outcomes & Retrospective` must be kept up to date as work +proceeds. + +Status: DRAFT + +## Purpose / big picture + +Roadmap item 3.13.2 asks for an "Advanced Usage" chapter in the user guide that +covers the `clean`, `graph`, and `manifest` subcommands, configuration +layering, and JSON diagnostics mode. Today the user guide already documents +these features individually across Sections 8 (CLI) and the JSON diagnostics +subsection, but there is no cohesive narrative that walks an intermediate user +through real-world workflows combining them. A newcomer who has completed the +quick-start and basic build guide has no guided path into power-user territory. + +After this work is complete: + +1. `docs/users-guide.md` will contain a new "Advanced Usage" chapter (Section + 12, placed after the security chapter) that ties together the utility + subcommands, layered configuration, and machine-readable diagnostics into + end-to-end workflows with worked examples. + +2. A new BDD feature file (`tests/features/advanced_usage.feature`) will + contain behavioural scenarios that prove the documented workflows are + accurate: cleaning, graph generation, manifest export, configuration file + layering with environment and CLI overrides, and JSON diagnostics + consumption. These scenarios serve as executable documentation that pins the + user guide's claims to real binary behaviour. + +3. Focused `rstest` integration tests will cover any edge cases and unhappy + paths that the BDD scenarios do not reach (for example, invalid config + values, conflicting precedence, and malformed JSON diagnostics). + +4. `docs/netsuke-design.md` will record the design decision that advanced + usage documentation is backed by behavioural tests rather than snapshot + tests. + +5. The roadmap checkbox for 3.13.2 in `docs/roadmap.md` will be marked done. + +Observable success: a user can read Section 12 of the user guide, follow the +worked examples, and see the same results. A developer can run +`cargo test --test bdd_tests advanced_usage` and see all scenarios pass. + +## Constraints + +- The user guide must use en-GB-oxendict spelling and grammar, following the + documentation style guide at `docs/documentation-style-guide.md`. +- No new crate dependencies. The existing test stack (`rstest`, `rstest-bdd` + v0.5.0, `assert_cmd`, `test_support`, `insta`) is sufficient. +- No changes to the `Cli` struct, `CliConfig`, or any public API surface. This + task is documentation and test coverage only; the features being documented + already exist and work. +- Files must stay under the 400-line cap from `AGENTS.md`. If a new test + module or step module grows too large, split it. +- Normalize Fluent bidi isolate markers in any test that inspects rendered + localized output, using `test_support::fluent::normalize_fluent_isolates` or + the shared BDD assertion helpers. +- BDD scenarios must reuse the existing step infrastructure where practical. + New step definitions are permitted only for assertions not already covered by + `tests/bdd/steps/manifest_command.rs`, `tests/bdd/steps/json_diagnostics.rs`, + `tests/bdd/steps/cli_config.rs`, or `tests/bdd/steps/process.rs`. +- Commit gating: `make check-fmt`, `make lint`, and `make test` must all pass + before the work is considered complete. Markdown changes also require + `make fmt`, `make markdownlint`, and `make nixie`. +- Mark roadmap item 3.13.2 done only after all validation gates pass. +- Record design decisions in `docs/netsuke-design.md`. +- Update `docs/users-guide.md` with any behaviour clarifications discovered + while writing the chapter. + +## Tolerances (exception triggers) + +- Scope: if implementation requires changes to more than 15 files or roughly + 600 net new lines, stop and reassess before continuing. +- Dependencies: if the work appears to require any new crate dependency, stop + and escalate. +- Behaviour drift: if the runtime behaviour for any documented workflow + materially disagrees with the user guide, stop to decide which source is + authoritative before writing final assertions. +- BDD brittleness: if a BDD scenario cannot be made deterministic after two + focused attempts, reduce the assertion to stable fragments and document the + instability. +- Iterations: if tests still fail after three focused correction attempts on + the same scenario, stop and escalate. +- `.feature` recompilation: if `.feature` edits do not trigger recompilation, + `touch tests/bdd_tests.rs` before the final `make test` run. + +## Risks + +- Risk: the existing BDD step library may not have steps for all the + assertions needed (for example, checking that stdout contains valid DOT + output, or that a config file overrides an environment variable). Severity: + low. Likelihood: medium. Mitigation: audit existing steps in Stage A. Add a + small, focused `tests/bdd/steps/advanced_usage.rs` module only for genuinely + missing steps. Prefer composing existing stdout/stderr/exit-code steps over + inventing new ones. + +- Risk: `make fmt` may introduce incidental wrap-only changes in unrelated + Markdown files. Severity: low. Likelihood: high. Mitigation: after + formatting, run `git diff` and restore unrelated files so the commit remains + scoped. This is a known pattern documented in project memory. + +- Risk: configuration layering BDD scenarios that set environment variables + may interfere with each other when tests run in parallel. Severity: medium. + Likelihood: medium. Mitigation: the repository already runs tests with + `--test-threads=1` for BDD tests. If isolation is still a problem, use the + existing `EnvLock` pattern from `tests/bdd/steps/cli_config.rs`. + +- Risk: the user guide's Section numbering may shift if other work has added + sections since the last known state. Severity: low. Likelihood: low. + Mitigation: read the current user guide table of contents in Stage A and + select the correct section number. + +## Progress + +- [ ] Stage A: Audit existing coverage and plan chapter structure. +- [ ] Stage B: Write the Advanced Usage chapter in `docs/users-guide.md`. +- [ ] Stage C: Add BDD behavioural scenarios. +- [ ] Stage D: Add focused `rstest` integration tests for edge cases. +- [ ] Stage E: Update design docs and roadmap. +- [ ] Stage F: Validation and evidence. + +## Surprises & discoveries + +(None yet.) + +## Decision log + +(None yet.) + +## Outcomes & retrospective + +(To be completed after implementation.) + +## Context and orientation + +The following repository areas matter for this task. + +### User documentation + +- `docs/users-guide.md`: The primary user-facing documentation.

Section 8.4 (lines 2030-2111) documents CLI design decisions + including OrthoConfig layering, theme resolution, and preference schema. + +### Implementation (read-only for this task) + +- `src/cli/mod.rs`: The `Cli` struct (OrthoConfig merge root) and `Commands` + enum (`Build`, `Clean`, `Graph`, `Manifest`). +- `src/cli/config.rs`: `CliConfig` struct with `ColourPolicy`, `SpinnerMode`, + `OutputFormat` enums and resolution methods. +- `src/cli/config_merge.rs`: `config_discovery()` sets up + `NETSUKE_CONFIG_PATH` and project roots. `merge_with_config()` applies the + layered precedence: defaults < config files < environment < CLI. +- `src/runner/mod.rs`: Command dispatch. `handle_build()` for the build + pipeline, `handle_ninja_tool()` for `clean` and `graph`, and the `manifest` + path for writing Ninja output. +- `src/main.rs`: `DiagMode` enum, startup JSON mode resolution, and JSON error + rendering. + +### Existing BDD infrastructure + +- `tests/bdd_tests.rs`: Entry point. Auto-discovers `.feature` files in + `tests/features/` and `tests/features_unix/`. +- `tests/bdd/steps/mod.rs`: Registry of all step modules (34 lines). New + modules must be registered here. +- `tests/bdd/fixtures/mod.rs`: `TestWorld` fixture (260 lines) storing CLI, + manifest, IR, Ninja, process, stdlib, and localization state. +- Key existing step modules: + - `tests/bdd/steps/manifest_command.rs`: Steps for workspace setup + (`a minimal Netsuke workspace`, `an empty workspace`), running netsuke + (`netsuke is run without arguments`, `netsuke is run with arguments ...`), + and generic stdout/stderr/exit-code assertions. + - `tests/bdd/steps/json_diagnostics.rs`: Steps for `stderr should be valid + diagnostics json` and `stderr diagnostics code should be "…"`. + - `tests/bdd/steps/cli_config.rs`: Steps for parsing typed config flags. + - `tests/bdd/steps/process.rs`: Process execution helpers. + - `tests/bdd/steps/progress_output.rs`: Fake-ninja installation. + +### Existing feature files (models for the new file) + +- `tests/features/novice_flows.feature`: 4 scenarios covering first run, + missing manifest, and help output. Direct predecessor of this task. +- `tests/features/json_diagnostics.feature`: 3 scenarios covering JSON error + reporting, stdout cleanliness, and verbose suppression. +- `tests/features/cli_config.feature`: 7 scenarios covering typed config enum + parsing and validation. +- `tests/features/manifest_subcommand.feature`: 3 scenarios covering manifest + output. + +### Existing integration tests + +- `tests/novice_flow_smoke_tests.rs`: `rstest`-based smoke tests for beginner + flows. Direct predecessor of this task's integration tests. +- `tests/assert_cmd_tests.rs`: End-to-end command tests using `assert_cmd` + with `path_with_fake_ninja()` and temporary workspaces. +- `tests/cli_tests/`: Integration test modules including `merge.rs` (config + precedence) and `locale.rs` (localization). + +### Key patterns + +- BDD steps use `#[given]`, `#[when]`, `#[then]` macros from `rstest-bdd`. +- Custom parameter types live in `tests/bdd/types/`. +- Fluent bidi isolate normalization uses + `test_support::fluent::normalize_fluent_isolates`. +- Fake-ninja is installed via helpers in `tests/bdd/steps/progress_output.rs` + and `test_support/src/netsuke.rs`. +- `build.rs` symbol anchors are needed for any new shared helpers in + `src/cli/mod.rs` or `src/cli_l10n.rs`, but this task should not need to add + any since no production code changes are planned. + +## Plan of work + +### Stage A. Audit existing coverage and plan chapter structure + +Read the current user guide to confirm the section numbering and identify any +gaps in the existing documentation of `clean`, `graph`, `manifest`, +configuration layering, and JSON diagnostics. Audit the existing BDD step +library to determine which steps can be reused and which new steps are needed. + +Deliverables: + +1. A decision logged about chapter placement (Section 12 or renumbered). +2. A decision logged about which existing BDD steps to reuse and which new + steps to add. +3. An outline of the chapter's subsections. + +Proposed chapter outline: + +- 12.1 The `clean` subcommand — removing build artefacts, interaction with + `phony` targets, worked example. +- 12.2 The `graph` subcommand — generating DOT dependency graphs, piping + through Graphviz, interpreting the output. +- 12.3 The `manifest` subcommand — exporting Ninja files for inspection, + streaming to stdout with `-`, using with `--emit` on the build command. +- 12.4 Configuration layering — the four-tier precedence model (defaults < + configuration files < environment variables < CLI flags), discovery + locations, the `NETSUKE_` environment prefix, `__` nesting separator, worked + examples with `.netsuke.toml`. +- 12.5 JSON diagnostics — enabling `--diag-json` or `--output-format json`, + schema overview, consuming diagnostics programmatically, interaction with + `--verbose` and stdout. + +Acceptance for Stage A: the outline is finalized and logged in the Decision +Log, and the step audit is complete. + +### Stage B. Write the Advanced Usage chapter + +Add Section 12 "Advanced Usage" to `docs/users-guide.md` immediately after the +current Section 11 (Security Considerations). The chapter must: + +1. Open with a brief introduction explaining that these features are aimed at + users who have mastered the basics and want to integrate Netsuke into more + sophisticated workflows. +2. Cover each subsection (12.1–12.5) with: + - A concise explanation of the feature's purpose. + - One or more worked examples showing exact commands and expected output. + - Notes on interaction with other features (for example, `graph` requires + a valid manifest, `--diag-json` suppresses progress output). +3. Use en-GB-oxendict spelling throughout. +4. Wrap paragraphs at 80 columns, code at 120 columns, per the style guide. +5. Include cross-references to earlier sections where appropriate (for example, + Section 8 for CLI options, Section 3 for manifest structure). + +After writing, run `make fmt` to apply mdformat, then `make markdownlint` and +`make nixie` to validate. + +Acceptance for Stage B: the new chapter reads coherently, passes markdown +linting, and a human reader can follow the worked examples. + +### Stage C. Add BDD behavioural scenarios + +Create `tests/features/advanced_usage.feature` with scenarios that pin the +documented workflows to real binary behaviour. The scenarios should cover: + +1. **Clean subcommand**: Given a minimal workspace, when `netsuke clean` is + run, then the command succeeds (or fails gracefully if no build has + occurred). +2. **Graph subcommand**: Given a minimal workspace, when `netsuke graph` is + run, then stdout contains DOT graph markers (for example `digraph` and `->`) + and the command succeeds. +3. **Manifest subcommand to file**: Given a minimal workspace, when + `netsuke manifest /tmp/test.ninja` is run, then the file exists and contains + Ninja build statements. +4. **Manifest subcommand to stdout**: Given a minimal workspace, when + `netsuke manifest -` is run, then stdout contains Ninja build statements and + stderr is clean. +5. **Configuration file overrides defaults**: Given a workspace with a + `.netsuke.toml` setting `verbose = true`, when netsuke is run, then verbose + output is visible (timing summary on success). +6. **Environment variable overrides config file**: Given a workspace with a + `.netsuke.toml` and `NETSUKE_VERBOSE=false` set, when netsuke is run, then + verbose output is suppressed. +7. **CLI flag overrides environment variable**: Given `NETSUKE_VERBOSE=false`, + when netsuke is run with `--verbose`, then verbose output is visible. +8. **JSON diagnostics on error**: Given an empty workspace, when netsuke is + run with `--diag-json build`, then stderr contains valid JSON diagnostics + and stdout is empty. +9. **JSON diagnostics on success**: Given a minimal workspace, when + `netsuke --diag-json manifest -` is run, then stdout contains Ninja output + and stderr is empty. + +If any scenarios require new step definitions not available in the existing +step library, add them in `tests/bdd/steps/advanced_usage.rs` and register the +module in `tests/bdd/steps/mod.rs`. + +Reuse existing steps wherever possible: + +- `Given a minimal Netsuke workspace` (from `manifest_command.rs`) +- `Given an empty workspace` (from `manifest_command.rs`) +- `Given a fake ninja executable that emits task status lines` (from + `progress_output.rs`) +- `When netsuke is run with arguments "..."` (from `manifest_command.rs`) +- `Then the command should succeed` / `fail` (from `manifest_command.rs`) +- `And stdout should contain "..."` / `stderr should contain "..."` + (from `manifest_command.rs`) +- `And stdout should be empty` / `stderr should be empty` + (from `manifest_command.rs`) +- `And stderr should be valid diagnostics json` (from + `json_diagnostics.rs`) + +New steps likely needed: + +- `Given a workspace with config file setting "" to ""` — creates + a `.netsuke.toml` in the workspace directory with the specified key-value + pair. +- `Given the environment variable "" is set to ""` — sets an + environment variable for the netsuke invocation. (Check whether an existing + step already covers this.) +- `And stdout should contain DOT graph output` — checks for `digraph` and + `->` markers in stdout (a thin wrapper over existing `stdout should contain`). +- `And the file "" should exist` — checks for file creation (may + already exist in `manifest_command.rs`). + +After adding scenarios, run: + +```sh +touch tests/bdd_tests.rs +cargo test --test bdd_tests advanced_usage 2>&1 | tee /tmp/advanced_usage_bdd.log +``` + +Acceptance for Stage C: all BDD scenarios pass. The feature file reads as +executable documentation that a non-developer can understand. + +### Stage D. Add focused `rstest` integration tests + +Add `tests/advanced_usage_tests.rs` (or extend an existing file if it stays +under 400 lines) with `rstest`-based tests covering edge cases and unhappy +paths not reached by the BDD scenarios: + +1. **Clean without prior build**: Run `netsuke clean` in a workspace that has + never been built. Assert the command handles this gracefully (either + succeeds with no-op or fails with a clear message). +2. **Graph with invalid manifest**: Run `netsuke graph` with a syntactically + invalid manifest. Assert failure with an actionable error message. +3. **Manifest to non-existent directory**: Run + `netsuke manifest /no/such/dir/out.ninja`. + Assert failure with a path-related error. +4. **Config layering precedence**: Use `NETSUKE_CONFIG_PATH` to point to a + temp config file, set an environment variable, and pass a CLI flag. Assert + that CLI wins over environment, which wins over file. +5. **JSON diagnostics with verbose suppression**: Run + `netsuke --diag-json --verbose graph` with an invalid manifest. Assert that + stderr is valid JSON without tracing noise. +6. **Invalid config value in file**: Create a `.netsuke.toml` with + `colour_policy = "loud"`. Assert that netsuke reports a validation error. + +Use `rstest` fixtures for repeated workspace setup. Reuse +`test_support::netsuke::run_netsuke_in()` and the fake-ninja helpers. + +After adding tests, run: + +```sh +cargo test --test advanced_usage_tests 2>&1 | tee /tmp/advanced_usage_tests.log +``` + +Acceptance for Stage D: all integration tests pass. Edge cases and unhappy +paths are covered. + +### Stage E. Update design docs and roadmap + +1. Update `docs/netsuke-design.md` Section 8.4 with a short paragraph + recording the design decision that the advanced usage chapter is backed by + behavioural tests to keep documentation and runtime behaviour in sync. + +2. Mark roadmap item 3.13.2 as done in `docs/roadmap.md` by changing + `- [ ] 3.13.2.` to `- [x] 3.13.2.` and its sub-bullets similarly. + +3. Run `make fmt`, `make markdownlint`, and `make nixie` to validate the + documentation changes. + +Acceptance for Stage E: the design doc records the decision, the roadmap +checkbox is ticked, and documentation gates pass. + +### Stage F. Validation and evidence + +Run the full repository gates. Because the environment auto-commits each turn, +all gates must pass before the turn ends. + +Suggested focused commands first: + +```sh +set -o pipefail +cargo test --test advanced_usage_tests 2>&1 | tee /tmp/advanced_usage_tests.log +``` + +```sh +set -o pipefail +touch tests/bdd_tests.rs +cargo test --test bdd_tests advanced_usage 2>&1 | tee /tmp/advanced_usage_bdd.log +``` + +Then the full repository gates: + +```sh +set -o pipefail +make check-fmt 2>&1 | tee /tmp/make-check-fmt.log +``` + +```sh +set -o pipefail +make lint 2>&1 | tee /tmp/make-lint.log +``` + +```sh +set -o pipefail +make test 2>&1 | tee /tmp/make-test.log +``` + +Because this task edits Markdown, also run the documentation gates: + +```sh +set -o pipefail +make fmt 2>&1 | tee /tmp/make-fmt.log +``` + +```sh +set -o pipefail +make markdownlint 2>&1 | tee /tmp/make-markdownlint.log +``` + +```sh +set -o pipefail +make nixie 2>&1 | tee /tmp/make-nixie.log +``` + +After `make fmt`, inspect `git diff` and restore any incidental wrap-only +changes in unrelated Markdown files before finalizing. + +## Concrete acceptance evidence + +The completed implementation should let a reviewer verify the task with the +following observable checks. + +### User guide chapter + +Reading `docs/users-guide.md` Section 12 should present a coherent advanced +usage narrative covering all five topics. The worked examples should be +reproducible by a user with a working Netsuke installation. + +### BDD scenarios + +Running `cargo test --test bdd_tests advanced_usage` should pass all scenarios +in `tests/features/advanced_usage.feature`. The feature file should read as +living documentation that a non-developer can follow. + +### Integration tests + +Running `cargo test --test advanced_usage_tests` should pass all tests. Edge +cases (clean without build, graph with bad manifest, manifest to bad path, +precedence ladder, JSON with verbose, invalid config value) should all be +covered. + +### Quality gates + +Running `make check-fmt`, `make lint`, and `make test` should all succeed. +Running `make markdownlint` and `make nixie` should also succeed. + +### Roadmap + +`docs/roadmap.md` item 3.13.2 and its sub-bullets should be checked off. + +## Validation and acceptance + +Quality criteria (what "done" means): + +- Tests: `make test` passes with zero failures. The new BDD scenarios and + integration tests are included in the suite. +- Lint/typecheck: `make check-fmt` and `make lint` pass with zero warnings. +- Documentation: `make markdownlint` and `make nixie` pass. The user guide + chapter is complete, correctly formatted, and uses en-GB-oxendict spelling. +- Roadmap: item 3.13.2 is marked complete. + +Quality method (how to check): + +- Run `make check-fmt`, `make lint`, `make test`, `make markdownlint`, and + `make nixie` in sequence. +- Read the new chapter in `docs/users-guide.md` for correctness and style. +- Read `tests/features/advanced_usage.feature` for clarity and coverage. + +## Idempotence and recovery + +All stages produce additive changes (new documentation, new test files, new +feature files). No existing code is modified except `docs/users-guide.md` (new +section appended), `docs/netsuke-design.md` (paragraph added to Section 8.4), +`docs/roadmap.md` (checkboxes ticked), and `tests/bdd/steps/mod.rs` (module +registration line added).

Always review `Netsukefile` manifests, especially those from untrusted sources, before building. + +## 12\. Advanced Usage + +This chapter covers features aimed at users who have mastered the basics and +want to integrate Netsuke into more sophisticated workflows. These include +utility subcommands (`clean`, `graph`, `manifest`), configuration file +discovery and layering, and JSON diagnostics mode for programmatic consumption +of Netsuke's output. + +### 12.1 The `clean` subcommand + +The `clean` subcommand removes build artefacts that Ninja tracked in its +internal database. It delegates directly to `ninja -t clean`: + +```sh +netsuke clean +``` + +This removes all output files declared in target `outs:` and action `outs:` +fields that Ninja has built. Files marked as `phony` targets are not removed +(since they have no physical output). + +**Interaction with phony targets:** If a target is declared as `phony: true`, +Ninja does not track it as a file, so `clean` ignores it. + +**Example workflow:** + +```sh +# Build the project +netsuke build + +# Remove all build outputs +netsuke clean + +# Rebuild from scratch +netsuke build +``` + +**Note:** Running `clean` in a workspace that has never been built (no +`.ninja_log` exists) will either succeed as a no-op or report that no build +state is available, depending on Ninja's behaviour. + +### 12.2 The `graph` subcommand + +The `graph` subcommand generates a Graphviz DOT representation of the build +dependency graph: + +```sh +netsuke graph > build.dot +dot -Tpng build.dot -o build.png +``` + +This produces a visual diagram showing: + +- Nodes for each target and action. +- Edges showing explicit dependencies (`ins:`, `needs:`). +- Order-only dependencies (`after:`). + +**Interpreting the output:** + +- Each node is labelled with the target or action name. +- Directed edges (`->`) point from prerequisites to dependants. +- Order-only dependencies are shown as dashed edges (if Graphviz is configured + to distinguish them). + +**Example workflow:** + +To understand why a particular target rebuilds when a file changes: + +```sh +netsuke graph | grep -A5 -B5 my_target +``` + +This shows the subgraph around `my_target` and helps trace back to its +dependencies. + +**Requirements:** The `graph` command requires a valid manifest. If the +manifest is syntactically invalid or contains structural errors, `graph` will +fail before rendering any DOT output. + +### 12.3 The `manifest` subcommand + +The `manifest` subcommand writes the generated Ninja build file to a specified +location without invoking Ninja: + +```sh +netsuke manifest out.ninja +``` + +This is useful for: + +- Inspecting the exact Ninja rules and build statements Netsuke generates. +- Debugging template expansion or rule generation issues. +- Integrating with tools that consume Ninja files directly. + +**Streaming to stdout:** + +Passing `-` as the path streams the manifest to stdout: + +```sh +netsuke manifest - | less +``` + +This avoids creating a temporary file and is convenient for quick inspection. + +**Comparison with `--emit`:** + +The build command also supports `--emit `, which writes the manifest and +then invokes Ninja on it: + +```sh +netsuke build --emit build.ninja +``` + +Use `manifest` when you want the Ninja file *without* running the build, and +`--emit` when you want both the file and the build execution. + +### 12.4 Configuration layering + +Netsuke uses a four-tier configuration precedence model provided by the +`ortho-config` library: + +1. **Defaults:** Hard-coded fallback values in the CLI. +2. **Configuration files:** Settings from `.netsuke.toml` (project or user + scope). +3. **Environment variables:** Prefixed with `NETSUKE_` (e.g., + `NETSUKE_VERBOSE`). +4. **CLI flags:** Command-line arguments (e.g., `--verbose`). + +Each layer overrides the previous one. This allows you to set stable defaults +in a configuration file and override them per-invocation with environment +variables or flags. + +**Configuration file discovery:** + +Netsuke searches for configuration files in the following order: + +1. Path specified by `NETSUKE_CONFIG_PATH` environment variable. +2. `.netsuke.toml` in the current working directory (project scope). +3. `.netsuke.toml` in the user's home directory (user scope). +4. Platform-specific user configuration directories (`$XDG_CONFIG_HOME/netsuke` + on Unix, `%APPDATA%\netsuke` on Windows). + +The first file found is used. Project-scoped configuration (current directory) +takes precedence over user-scoped configuration (home directory or XDG +locations). + +**Configuration file format:** + +Configuration files are TOML. Supported keys match the CLI option names: + +```toml +# .netsuke.toml +verbose = true +colour_policy = "always" +spinner_mode = "always" +theme = "unicode" +default_targets = ["hello", "test"] +``` + +**Environment variables:** + +Environment variables use the `NETSUKE_` prefix and convert kebab-case option +names to screaming snake case: + +- `--verbose` → `NETSUKE_VERBOSE=true` +- `--colour-policy` → `NETSUKE_COLOUR_POLICY=always` +- `--spinner-mode` → `NETSUKE_SPINNER_MODE=never` + +For nested fields or indexed lists, use double underscore separators: + +- `NETSUKE_DEFAULT_TARGETS__0=hello` +- `NETSUKE_DEFAULT_TARGETS__1=test` + +**Example layering workflow:** + +Suppose you have a project configuration file: + +```toml +# .netsuke.toml (project scope) +verbose = true +colour_policy = "auto" +``` + +You can override `colour_policy` for a single invocation: + +```sh +NETSUKE_COLOUR_POLICY=never netsuke build +``` + +Or override both settings via CLI flags: + +```sh +netsuke build --colour-policy always --verbose=false +``` + +**Precedence verification:** + +To see which configuration is active, inspect the verbose output (if enabled) +or use the `--help` output, which shows the default values: + +```sh +netsuke --help +``` + +For more complex setups, run with `--verbose` and check the diagnostic output +at the start of the build. + +### 12.5 JSON diagnostics + +Netsuke supports a JSON diagnostics mode for programmatic consumption of error +messages and structured output. Enable it with: + +```sh +netsuke --diag-json build +``` + +Or via the environment variable: + +```sh +NETSUKE_OUTPUT_FORMAT=json netsuke build +``` + +**JSON diagnostics on error:** + +When a command fails, stderr contains a JSON object with structured error +information: + +```json +{ + "type": "diagnostic", + "severity": "error", + "code": "E_MANIFEST_NOT_FOUND", + "message": "Manifest 'Netsukefile' not found in the current directory.", + "help": "Ensure the manifest exists or pass `--file` with the correct path." +} +``` + +**Interaction with stdout:** + +When JSON diagnostics are enabled, stdout remains clean for machine-readable +output (e.g., from `manifest -`). All diagnostic messages go to stderr in JSON +format. + +**Interaction with `--verbose`:** + +Verbose logging is suppressed in JSON mode. The `--verbose` flag does not add +tracing output when `--diag-json` is active, preventing pollution of the +structured JSON stream. + +**Example workflow - CI integration:** + +In a continuous integration pipeline, parse Netsuke's JSON diagnostics to +report structured failures: + +```sh +netsuke --diag-json build 2>diagnostics.json +if [ $? -ne 0 ]; then + jq '.code, .message' diagnostics.json +fi +``` + +This allows the CI system to categorize errors by code and present actionable +messages to developers. diff --git a/tests/bdd/steps/advanced_usage.rs b/tests/bdd/steps/advanced_usage.rs new file mode 100644 index 00000000..859da687 --- /dev/null +++ b/tests/bdd/steps/advanced_usage.rs @@ -0,0 +1,101 @@ +//!

This is done by adding a new map `env_vars_forward` in TestWorld and updating `track_env_var` to accept an optional new value to forward. All steps that set or unset environment variables now forward the intended values. The command builder uses these forwarded variables to set the environment explicitly, avoiding reading from the process environment directly. This improves test isolation and consistency when invoking netsuke subprocesses.

This eliminates the need for BDD step functions to acquire a separate `EnvLock` to read the environment variable before creating the guard. Changes: - Add `EnvGuard::original_ref()` returning `Option<&OsString>` - Add `NinjaEnvGuard::original_ref()` delegating to inner guard - Update `install_test_ninja` in tests/bdd/steps/process.rs to use peek - Update `install_fake_ninja_with_config` in tests/bdd/steps/progress_output.rs to use peek - Rename shadowed `guard` variable to `ninja_guard` to fix clippy warning This change improves the ergonomics of the guard API by allowing callers to inspect the original value without needing to understand the locking protocol.

Fix `run_netsuke_in_with_env` to forward the host PATH after `env_clear()` instead of setting it to an empty string. This aligns with the pattern used in `build_netsuke_command` (tests/bdd/steps/manifest_command.rs), which already reads `std::env::var_os("PATH")` after clearing the environment. Tests requiring custom search paths can override via `extra_env`. 2. Collapse three separate config precedence tests into a single parameterized `#[rstest]` function `verbose_config_precedence`. The consolidated test covers the same three scenarios (config file overrides defaults, env var overrides config file, CLI flag overrides env and config) with reduced duplication and clearer test structure. Changes: - test_support/src/netsuke.rs: Replace `env("PATH", "")` with conditional forwarding of host PATH - tests/advanced_usage_tests.rs: Merge three config precedence tests into one parameterized test (68 lines → 34 lines, net -34 lines) All tests pass (910+ total, including 227 BDD tests and 9 advanced usage tests).

Change `run_netsuke` to use isolated execution path instead of inheriting host environment. Previously used `run_netsuke_in` which inherits host `NETSUKE_*` environment variables. Now uses `run_netsuke_in_with_env` with explicit environment passing, ensuring tests don't pick up host config. 2. Fix incomplete assertion in `invalid_config_value_reports_validation_error`: now validates that error message includes all three valid options (auto, always, never) instead of just two. This ensures the error message provides complete guidance to users. Changes: - Replace `run_netsuke_in` with `run_netsuke_in_with_env` in `run_netsuke` - Build explicit environment list for NINJA_ENV when needed - Add "never" to validation assertion alongside "auto" and "always" All 10 advanced usage tests and 227 BDD tests pass. Clippy clean.

Correct `track_env_var` signature to show three-argument form and explain `env_vars_forward` side-effect for child process environment forwarding. 2. Add `env_vars_forward` to Environment state row in TestWorld field groups table with clarified column descriptions. 3.

Document `given_config_file_with_setting` BDD step and `toml = "0.8"` dev-dependency, including TOML value coercion rules and extension policy. All changes are documentation-only.

Remove the host-process `override_ninja_env` guard that was ineffective because `run_netsuke_in_with_env` calls `env_clear()`. 2. Build a merged environment vector that includes caller-supplied `extra_env` entries plus a `("NETSUKE_NINJA", path_str)` entry when `ninja_env` is `Some`, mirroring the pattern already used in `run_netsuke`. 3. Replace `ninja_env::NINJA_ENV` constant references with string literal `"NETSUKE_NINJA"` to avoid taking a dependency on the `ninja_env` crate from integration tests. 4. Remove unused `use test_support::env::{SystemEnv, override_ninja_env};` import. This ensures that configuration-layering tests using `run_netsuke_with_env` correctly forward the fake ninja path to child processes in the isolated environment created by `env_clear()`.
