MAGICFFI ======== MAGICFFI is a CFFI interface to libmagic(3), the file type determination library using ``magic'' numbers. Homepage is http://common-lisp.net/project/magicffi. Download -------- To check out the git repository, run: ---------------------------------------------------------------------- $ git clone git://github.com/dochang/magicffi.git ---------------------------------------------------------------------- To browse code online, go to: http://github.com/dochang/magicffi You can also download the repo's snapshot. Zipball:: http://github.com/dochang/magicffi/zipball/master Tarball:: http://github.com/dochang/magicffi/tarball/master Installation ------------ MAGICFFI depends on the following lisp libraries: - CFFI - CL-PPCRE (used by the internal flags generator) The following system packages are also required: - libmagic-dev - libc6-dev - gcc You have to install them on your system before loading magicffi. Tutorial -------- ---------------------------------------------------------------------- > (asdf:load-system :magicffi) > (use-package :magicffi) > (with-open-magic (magic '(:mime-type :symlink)) (magic-load magic) (magic-file magic #P"magicffi.asd")) "text/plain" ---------------------------------------------------------------------- Documentation ------------- All external symbols of the package `MAGICFFI` are listed in `package.lisp`. Check out their docstrings for help. Magic Flags ~~~~~~~~~~~ You can use either constants or keyword list as magic flags. I.e., ---------------------------------------------------------------------- (magic-open (logxor +magic-mime-type+ +magic-symlink+)) ---------------------------------------------------------------------- is equivalent to ---------------------------------------------------------------------- (magic-open '(:mime-type :symlink)) ---------------------------------------------------------------------- The constant name and keyword name of a flag are based on its C name. See the following table for the pattern: .Magic flags naming convension |========================================== |C name |Lisp constant |Lisp keyword |`MAGIC_NONE` |`+MAGIC-NONE+` |`:NONE` |========================================== All constant names are exported.
