An Emacs dynamic module for strptime(3)

Emacs provides format-time-string which is basically a wrapper of strftime(3). strptime(3) is the converse of strftime(3), however Emacs doesn't have a wrapper of it, hence this module.

(strptime "2020-04-01" "%Y-%m-%d")
;; => (0 0 0 1 4 2020 3 nil 0)

(strptime "2020-04-01T07:39:26+0800" "%FT%T%z")
;; => (26 39 7 1 4 2020 3 nil 28800)

(strptime "2020-04-XX" "%Y-%m-%d")
;; error→ STRING and FORMAT not match: "2020-04-XX", "%Y-%m-%d"

Setup

Issue the make command to build the dynamic module, e.g.,

~/s/strptime.el $ make
cc -shared -fpic strptime-core.c -o strptime-core.so

Add load-path and load the library, e.g.,

(add-to-list 'load-path "~/src/strptime.el")
(require 'strptime)
