@@ -157,26 +157,46 @@ Convert papers from PDF to Markdown using MinerU.
**Options:**
- `--library PATH`: Specify library directory
- `--paper-id ID`: Convert specific paper only
- `--retry-failed`: Retry papers with failed conversion status
- `--force`: Force reconvert all papers (including successful ones)
- `--no-ui`: Disable rich UI display (useful for scripting)
**Examples:**
```bash
# Convert all pending papers
# Convert all pending papers (with rich UI)
paperlib convert
# Retry failed conversions
paperlib convert --retry-failed
# Force reconvert all papers
paperlib convert --force
# Convert specific paper
paperlib convert --paper-id arxiv-2212_06340
# Convert without UI (for scripts)
paperlib convert --no-ui
# Convert in specific library
paperlib convert --library ~/research
```
**Behavior:**
- Processes papers with `conversion_status: pending`
- Uses MinerU for PDF to Markdown conversion
- Processes papers with `conversion_status: pending` (or failed with `--retry-failed`)
- Uses MinerU for PDF to Markdown conversion with CPU pipeline backend
- Shows rich UI with progress bar and live MinerU output (unless `--no-ui`)
- Updates metadata with conversion status
- Creates conversion logs in `logs/` directory
- Post-processes markdown to fix image references (`images/``assets/`)
- Handles conversion failures gracefully
**Rich UI Features:**
- Progress bar showing papers converted
- Live streaming of MinerU output
- Current paper being processed
- Color-coded output (errors in red, progress in blue, etc.)
