71 What would be a lispy approach? I tried:
\r
73 (defun notmuch-subject-to-patch-filename (subject)
\r
74 "Convert a typical patch mail subject line into a suitable filename."
\r
76 (let ((filename subject)
\r
78 '(("^ *\\(\\[[^]]*\\]\\)? *" . "")
\r
80 ("[^A-Za-z0-9._-]+" . "-")
\r
82 (mapc (lambda (transform)
\r
83 (setq filename (replace-regexp-in-string (car transform) (cdr transfo=
\r
86 (substring filename 0 (min (length filename) 50)))
\r
89 ...but that seems a bit unwieldy. `let*' looks best, but still feels a
\r
92 (defun notmuch-subject-to-patch-filename (subject)
\r
93 "Convert a typical patch mail subject line into a suitable filename."
\r
95 (let* ((filename (replace-regexp-in-string "^ *\\(\\[[^]]*\\]\\)? *" "" =
\r
97 (filename (replace-regexp-in-string "[. ]*$" "" filename))
\r
98 (filename (replace-regexp-in-string "[^A-Za-z0-9._-]+" "-" filename))
\r
99 (filename (replace-regexp-in-string "\\.+" "." filename)))
\r
100 (substring filename 0 (min (length filename) 50)))
