Adds new functionality to convert existing lecture .qmd files to RevealJS slides, preserving R code chunks, callouts, and structure. Features: - `teach slides --week N` auto-detects lecture files from teach-config.yml - `teach slides --from-lecture FILE` converts specific files - `--dry-run` shows content analysis before generating - Multi-part weeks (defined in config) generate separate slide files - Preserves R code chunks for statistics examples - Converts H1 to section slides, H2 to regular slides - Handles callouts, columns, and TL;DR boxes Usage: teach slides --week 1 --dry-run # Preview teach slides --week 1 # Generate teach slides --from-lecture lectures/week-02_crd.qmd Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Replace echo with printf '%s\n' to prevent escape sequence interpretation. echo interprets backslash sequences like \t, \b, \v, \a, \u as control characters, which corrupts LaTeX commands: - \tau → tab + "au" - \beta → backspace + "eta" - \varepsilon → vertical tab + "arepsilon" - \underbrace → unicode escape + "nderbrace" - \alpha → bell + "lpha" printf '%s\n' treats the string literally, preserving all backslashes. Fixes corruption observed when converting lecture notes with mathematical formulas to RevealJS slides. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
