The detail field truncation in human.rs only applied to TTY output, causing lines to exceed 80 columns when piping to cat or using --no-color. Fix: Apply truncation uniformly across all output modes: - TTY mode: Use actual terminal width from terminal_size crate - Non-TTY/--no-color: Assume 80 columns and truncate accordingly - Detail field max width: term_width - 38 columns Max line width now exactly 80 characters for all output modes. Acceptance criteria verified: - TTY colored table with summary ✓ - Non-TTY plain text, no ANSI ✓ - --json single JSON object ✓ - --json summary counts ✓ - --features list, exit 0 ✓ - --no-color plain text in TTY ✓ - 80-column terminal width ✓ - N/A excluded from human, in JSON ✓ Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

# pdftract-1w5u1: Output formats verification
|
|
|
|
## Summary
|
|
|
|
The three output formats for `pdftract doctor` were already implemented in:
|
|
- `crates/pdftract-cli/src/doctor/output/human.rs` - colored table output
|
|
- `crates/pdftract-cli/src/doctor/output/json.rs` - JSON output
|
|
- `crates/pdftract-cli/src/doctor/output/features.rs` - feature listing
|
|
|
|
## Acceptance Criteria Verification
|
|
|
|
### PASS: Default (TTY) colored table output
|
|
- Output shows colored table with Check, Status, Detail columns
|
|
- ANSI colors: OK=green, WARN=yellow, FAIL=red
|
|
- Summary line at bottom: "N OK, M WARN, K FAIL"
|
|
- Verified: `./target/release/pdftract doctor` produces properly formatted table
|
|
|
|
### PASS: Non-TTY plain text output
|
|
- Piped output (via `| cat`) strips ANSI escape codes
|
|
- Same content structure as TTY but without colors
|
|
- Summary line included
|
|
- Verified: `./target/release/pdftract doctor | cat` produces plain text
|
|
|
|
### PASS: --json output
|
|
- Single JSON object with `{summary: {ok, warn, fail, not_applicable}, checks: [...]}`
|
|
- JSON parses correctly with `jq`
|
|
- Status values are "OK", "WARN", "FAIL", "N/A"
|
|
- Verified: `./target/release/pdftract doctor --json | jq '.summary.fail'` returns integer
|
|
|
|
### PASS: --json jq filtering
|
|
- `./target/release/pdftract doctor --json | jq '.summary'` shows correct counts
|
|
- `./target/release/pdftract doctor --json | jq '.checks[] | select(.status == "WARN")'` filters correctly
|
|
|
|
### PASS: --features output
|
|
- Lists compiled features, one per line
|
|
- Exit code 0
|
|
- No diagnostic checks run
|
|
- Verified: `./target/release/pdftract doctor --features` returns exit code 0
|
|
- Note: Default build has no features enabled ("default" feature set), so output is empty
|
|
|
|
### PASS: --no-color output
|
|
- Plain text output even in TTY
|
|
- No ANSI escape codes
|
|
- Same structure as default
|
|
- Verified: `./target/release/pdftract doctor --no-color` produces plain text table
|
|
|
|
### PASS: 80-column terminal width
|
|
- Output fits within 80 columns without wrapping
|
|
- Column widths: name=30, status=6, detail=flex
|
|
- Separator line is exactly 80 characters
|
|
- **FIX:** Detail truncation now applies uniformly to TTY and non-TTY output
|
|
- Previously: Truncation only in TTY mode, causing >80-char lines when piped or using --no-color
|
|
- Now: Truncation always based on 80 columns (TTY uses actual width, non-TTY assumes 80)
|
|
|
|
### PASS: N/A row handling
|
|
- N/A checks excluded from human output (verified in code: line 41-43 of human.rs)
|
|
- N/A checks included in JSON with status="N/A" (verified in code: line 28-31 of json.rs)
|
|
|
|
## Dependencies
|
|
|
|
- `atty` crate for TTY detection (already in dependencies)
|
|
- `terminal_size` crate for terminal width detection (already in dependencies)
|
|
- `termcolor` crate for ANSI color handling (already in dependencies)
|
|
|
|
## Implementation Notes
|
|
|
|
### Fix Applied
|
|
|
|
**File:** `crates/pdftract-cli/src/doctor/output/human.rs`
|
|
|
|
**Issue:** Detail field truncation only applied to TTY output. When piping to `cat` or using `--no-color`, long detail strings were not truncated, causing lines to exceed 80 columns.
|
|
|
|
**Solution:** Modified truncation logic (lines 77-89) to:
|
|
1. Determine terminal width: TTY uses actual width, non-TTY assumes 80 columns
|
|
2. Calculate max detail width: `term_width - 38` (30 name + 1 space + 6 status + 1 space)
|
|
3. Truncate detail to max width with "..." suffix if needed
|
|
|
|
**Result:** Max line width now exactly 80 characters for all output modes.
|
|
|
|
### Existing Implementation
|
|
|
|
The output modules were implemented with:
|
|
1. **TTY detection** via `std::io::IsTerminal` trait (nightly feature stabilized)
|
|
2. **Color control** via `termcolor` crate with `ColorChoice` enum
|
|
3. **Terminal width detection** via `terminal_size` crate
|
|
4. **Detail truncation** for long strings in TTY mode
|
|
5. **Summary line** at bottom with bold formatting
|
|
6. **Stderr output** for failures (in addition to stdout summary)
|
|
|
|
All acceptance criteria are met. One fix was applied to ensure 80-column compliance for non-TTY output.
