Emacs is largely a Lisp program, but has a C core. What's the ratio of SLOC between the two languages, and how have they changed over time?
Note that:
- C code looked for under
src/. - Lisp code looked for under
lisp/. - C sources in
lib/andlib-src/are not counted (see README). - C header files are ignored.
- Comment/blank lines are ignored.
| Emacs Version | Lines of Lisp | Lines of C | Ratio |
|---|---|---|---|
| 29.1 | 1199775 | 306772 | 3.91 |
| 28.2 | 1141528 | 257981 | 4.42 |
| 27.2 | 1100237 | 252476 | 4.36 |
| 26.3 | 1081561 | 235791 | 4.59 |
| 25.3 | 1061723 | 226388 | 4.69 |
| 24.5 | 1042357 | 215830 | 4.83 |
Between 28 and 29 we see a 19% increase in the size of the C. I wonder what changed? Perhaps the PGTK backend?
