From 7f353e925b7dbd6d0c16962e0e822aea0093308b Mon Sep 17 00:00:00 2001 From: Craig Jennings Date: Mon, 11 May 2026 17:17:54 -0500 Subject: perf(lorem-optimum): speed up the Markov generation path `cj/markov-join-tokens' collects tokens in a list and `mapconcat's once instead of repeated string concatenation. `cj/markov-generate' uses `push'/`nreverse' instead of repeated `append'. The Markov keys are cached as a vector so random key selection is O(1). Re-enabled the benchmark tests (the `:slow' tags were stale) and added a `cj/lipsum-title' test after byte-compilation flagged a malformed form there. `assets/liber-primus.txt' is left as-is (36 KB / 5,374 words, small enough not to need trimming). 100K-word learning now measures about 196 ms. --- tests/test-lorem-optimum.el | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'tests/test-lorem-optimum.el') diff --git a/tests/test-lorem-optimum.el b/tests/test-lorem-optimum.el index ca2e52f43..40bdc6840 100644 --- a/tests/test-lorem-optimum.el +++ b/tests/test-lorem-optimum.el @@ -238,5 +238,14 @@ (let ((result (cj/markov-generate chain 2))) (should (stringp result))))) +(ert-deftest test-title-generation-produces-title () + "Should generate a non-empty title from the global chain." + (let ((cj/lipsum-chain + (test-learn "lorem ipsum dolor sit amet consectetur adipiscing elit"))) + (let ((result (cj/lipsum-title))) + (should (stringp result)) + (should (> (length result) 0)) + (should (string-match-p "^[[:upper:]]" result))))) + (provide 'test-lorem-optimum) ;;; test-lorem-optimum.el ends here -- cgit v1.2.3
