library should fulfil two aims: Testing features when building Emacs
distros (especially under Windows) and providing information for users
without the complete source tree.
I took up the idea from Alan Third and completed some missing "standard"
features (from nt/INSTALL.W64):
(defun insert-feature (description test)
(indent-to 2)
(insert (if test "✔" "✖"))
(indent-to 5)
(insert description)
(insert "\n"))
;; feature list from nt/INSTALL.W64
(defun list-features ()
(interactive)
(switch-to-buffer
(get-buffer-create "*Features*"))
(read-only-mode -1)
(erase-buffer)
(insert "Standard Emacs Features:\n")
;; harfbuzz
(insert-feature "Harfbuzz - text shaping library "
(eq 'harfbuzz
(car (frame-parameter nil 'font-backend))))
;; zlib
(insert-feature "Zlib - compression library" (zlib-available-p))
;; libxml
(insert-feature "xml2 - parser library" (libxml-available-p))
;; lcms lcms2-available-p
(insert-feature "lcms2 - color translator library" (image-type-available-p
'pbm))
(insert-feature "JSON - data exchange library"
(progn (require 'json) (fboundp 'json-serialize)))
(insert-feature "GNUTLS - secure communication library"
(gnutls-available-p))
(insert-feature "pbm - image library" (image-type-available-p 'pbm))
(insert-feature "xpm - image library" (image-type-available-p 'xpm))
(insert-feature "bmp - image library" (image-type-available-p 'bmp))
(insert-feature "gif - image library" (image-type-available-p 'gif))
(insert-feature "png - image library" (image-type-available-p 'png))
(insert-feature "xpm - image library" (image-type-available-p 'xpm))
(insert-feature "jpeg - image library" (image-type-available-p 'jpeg))
(insert-feature "tiff - image library" (image-type-available-p 'tiff))
(insert-feature "svg - image library" (image-type-available-p 'svg))
(insert-feature "native images" (image-type-available-p 'native-image))
;; what are native images?
;; jansson = json?
;; thread support?
;; modules
;; gmp <- gnutls
(read-only-mode 1))
What do you think?
By the way, please tell me what are native images?
