* Add support for colored and styled underlines on tty framesMohsin Kaleem2024-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/dispextern.h (face, face_underline_type, syms_of_xfacse) (internal-set-lisp-face-attribute) (gui_supports_face_attributes_p): Add definitions for new underline styles of Double-line, Dots and Dashes. Rename FACE_UNDER_LINE and FACE_UNDER_WAVE to make definitions consistent. Delete tty_underline_p from the face struct and use just underline going forward. Add a flag to check whether styled underlines are available. * lisp/cus-face.el (custom-face-attributes): Add entries for Double-line, Dots and Dashes so they can be set through `customize'. * src/termchar.c (tty_display_info): Add an entry for the escape sequence to set the underline style and color on terminal frames. * src/term.c (init_tty, tty_capable_p, turn_on_face): Read and save the underline style escape sequence from the Smulx termcap (alternatively if the Su flag is set use a default sequence). Allow checking for support of styled underlines in the current terminal frame. Output the necessary escape sequences to activate a styled underline on turn_on_face; this is currently only used for the new special underline styles, a default straight underline will still use the "us" termcap. Output escape sequence to set underline color when set in the face and supported by the tty. Save a default value for this sequence on init_tty when styled underlines are supported. * src/xfaces.c (tty_supports_face_attributes_p, realize_tty_face) (map_tty_color): Assert whether styled underlines are supported by the current terminal on display-supports-face-attributes-p checks. Populate the correct underline style and color in the face spec when realizing a face. Allow map_tty_color to map underline colors alongside foreground and background. The interface of map_tty_color was amended to allow the caller to supply the underline color instead of accessing it through the face attributes. (bug#62994) * src/xterm.c (x_draw_glyph_string): Updated to use renamed FACE_UNDERLINE_SINGLE and FACE_UNDERLINE_WAVE face_underline_type enumerations.
* bytecomp.el: Rewrite the way we print dynamic docstringsStefan Monnier2024-02-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We used to print dynamic docstrings "manually" for two reasons: - References should look like `(#$ . POS)` but `prin1` was unable to print just `#$` for an sexp. - `make-docfile` needed to find those docstrings and the object to which they belonged. The second point is moot now that we don't use `make-docfile` on `.elc` files. So this patch lifts the first restriction, using `print-number-table`. The rest of the patch then simplifies and regularises the bytecompiler's generation of dynamic docstrings, which can now also easily be done for "inner" defvars and other places. * src/print.c (print_preprocess, print_object): Handle strings in `print-number-table`. (Vprint_number_table): Improve docstring. * lisp/emacs-lisp/bytecomp.el: (byte-compile--list-with-n): New function. (byte-compile--docstring-style-warn): Rename from `byte-compile-docstring-style-warn` and change calling convention. (byte-compile--\#$, byte-compile--docstrings): New vars. (byte-compile-close-variables): Bind them. (byte-compile--docstring): New function. (byte-compile-from-buffer): Set `byte-compile--\#$`. (byte-compile-output-file-form): Use `byte-compile--\#$` instead of special casing specific forms. (byte-compile--output-docform-recurse, byte-compile-output-docform): Delete functions. (byte-compile-file-form-autoload, byte-compile-file-form-defalias) (byte-compile-file-form-defvar-function, byte-compile-lambda): Use `byte-compile--docstring` and `byte-compile--list-with-n`. (byte-compile--declare-var): Add optional `not-toplevel` arg. (byte-compile-defvar): Add `toplevel` arg. Use `byte-compile--docstring`. (byte-compile-file-form-defvar): Delegate to `byte-compile-defvar`. (byte-compile--custom-declare-face): New function. Use it for `custom-declare-face`. (byte-compile-file-form-defmumble): Use `byte-compile-output-file-form` * src/doc.c (Fdocumentation_stringp): New function. (syms_of_doc): Defsubr it. (store_function_docstring): Remove left-over code from when we used DOC for the docstring of some Lisp files. * lisp/cus-face.el (custom-declare-face): Accept dynamic docstrings. * lisp/faces.el (face-documentation): Handle dynamic docstrings. * lisp/help-fns.el (describe-face): Simplify accordingly.

* | Adjust custom-face-attributes for 'regular' weightRobert Pluim2021-11-26
| | | | | | | | | | | | | | | | | | | | Following the changes to support "medium" weight fonts, the weight for "normal" fonts is now reported as 'regular', which caused customize-face to display faces as lisp-expressions, since it didn't recognize that. This has been corrected. * lisp/cus-face.el (custom-face-attributes): Recognize 'regular' as a weight.

|/ | | | | | | | | | | | | | | | | | | | | Theme settings now generally aren't actually applied until a call to `enable-theme-, either one made explicitly or implicitly through `load-theme' with NO-ENABLE nil. This change has the effect of not applying theme changes just because we load a lisp file containing a theme specification.

* Prefer HTTPS to FTP and HTTP in documentationPaul Eggert2017-09-13
| | | | | | | | | | | | | Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.
