|
;; About ps-print
|
|
;; --------------
|
|
;;
|
|
;; This package provides printing of Emacs buffers on PostScript
|
|
;; printers; the buffer's bold and italic text attributes are
|
|
;; preserved in the printer output. Ps-print is intended for use with
|
|
;; Emacs 19 or Lucid Emacs, together with a fontifying package such as
|
|
;; font-lock or hilit.
|
|
;;
|
|
;;
|
|
;; Using ps-print
|
|
;; --------------
|
|
;;
|
|
;; The Commands
|
|
;;
|
|
;; Ps-print provides eight commands for generating PostScript images
|
|
;; of Emacs buffers:
|
|
;;
|
|
;; ps-print-buffer
|
|
;; ps-print-buffer-with-faces
|
|
;; ps-print-region
|
|
;; ps-print-region-with-faces
|
|
;; ps-spool-buffer
|
|
;; ps-spool-buffer-with-faces
|
|
;; ps-spool-region
|
|
;; ps-spool-region-with-faces
|
|
;;
|
|
;; These commands all perform essentially the same function: they
|
|
;; generate PostScript images suitable for printing on a PostScript
|
|
;; printer or displaying with GhostScript. These commands are
|
|
;; collectively referred to as "ps-print- commands".
|
|
;;
|
|
;; The word "print" or "spool" in the command name determines when the
|
|
;; PostScript image is sent to the printer:
|
|
;;
|
|
;; print - The PostScript image is immediately sent to the
|
|
;; printer;
|
|
;;
|
|
;; spool - The PostScript image is saved temporarily in an
|
|
;; Emacs buffer. Many images may be spooled locally
|
|
;; before printing them. To send the spooled images
|
|
;; to the printer, use the command `ps-despool'.
|
|
;;
|
|
;; The spooling mechanism was designed for printing lots of small
|
|
;; files (mail messages or netnews articles) to save paper that would
|
|
;; otherwise be wasted on banner pages, and to make it easier to find
|
|
;; your output at the printer (it's easier to pick up one 50-page
|
|
;; printout than to find 50 single-page printouts).
|
|
;;
|
|
;; Ps-print has a hook in the `kill-emacs-hooks' so that you won't
|
|
;; accidentally quit from Emacs while you have unprinted PostScript
|
|
;; waiting in the spool buffer. If you do attempt to exit with
|
|
;; spooled PostScript, you'll be asked if you want to print it, and if
|
|
;; you decline, you'll be asked to confirm the exit; this is modeled
|
|
;; on the confirmation that Emacs uses for modified buffers.
|
|
;;
|
|
;; The word "buffer" or "region" in the command name determines how
|
|
;; much of the buffer is printed:
|
|
;;
|
|
;; buffer - Print the entire buffer.
|
|
;;
|
|
;; region - Print just the current region.
|
|
;;
|
|
;; The -with-faces suffix on the command name means that the command
|
|
;; will include font, color, and underline information in the
|
|
;; PostScript image, so the printed image can look as pretty as the
|
|
;; buffer. The ps-print- commands without the -with-faces suffix
|
|
;; don't include font, color, or underline information; images printed
|
|
;; with these commands aren't as pretty, but are faster to generate.
|
|
;;
|
|
;; Two ps-print- command examples:
|
|
;;
|
|
;; ps-print-buffer - print the entire buffer,
|
|
;; without font, color, or
|
|
;; underline information, and
|
|
;; send it immediately to the
|
|
;; printer.
|
|
;;
|
|
;; ps-spool-region-with-faces - print just the current region;
|
|
;; include font, color, and
|
|
;; underline information, and
|
|
;; spool the image in Emacs to
|
|
;; send to the printer later.
|
|
;;
|
|
;;
|
|
;; Invoking Ps-Print
|
|
;; -----------------
|
|
;;
|
|
;; To print your buffer, type
|
|
;;
|
|
;; M-x ps-print-buffer
|
|
;;
|
|
;; or substitute one of the other seven ps-print- commands. The
|
|
;; command will generate the PostScript image and print or spool it as
|
|
;; specified. By giving the command a prefix argument
|
|
;;
|
|
;; C-u M-x ps-print-buffer
|
|
;;
|
|
;; it will save the PostScript image to a file instead of sending it
|
|
;; to the printer; you will be prompted for the name of the file to
|
|
;; save the image to. The prefix argument is ignored by the commands
|
|
;; that spool their images, but you may save the spooled images to a
|
|
;; file by giving a prefix argument to `ps-despool':
|
|
;;
|
|
;; C-u M-x ps-despool
|
|
;;
|
|
;; When invoked this way, `ps-despool' will prompt you for the name of
|
|
;; the file to save to.
|
|
;;
|
|
;; Any of the `ps-print-' commands can be bound to keys; I recommend
|
|
;; binding `ps-spool-buffer-with-faces', `ps-spool-region-with-faces',
|
|
;; and `ps-despool'. Here are the bindings I use on my Sun 4 keyboard:
|
|
;;
|
|
;; (global-set-key 'f22 'ps-spool-buffer-with-faces) ;f22 is prsc
|
|
;; (global-set-key '(shift f22) 'ps-spool-region-with-faces)
|
|
;; (global-set-key '(control f22) 'ps-despool)
|
|
;;
|
|
;;
|
|
;; The Printer Interface
|
|
;; ---------------------
|
|
;;
|
|
;; The variables `ps-lpr-command' and `ps-lpr-switches' determine what
|
|
;; command is used to send the PostScript images to the printer, and
|
|
;; what arguments to give the command. These are analogous to
|
|
;; `lpr-command' and `lpr-switches'.
|
|
;; Make sure that they contain appropriate values for your system;
|
|
;; see the usage notes below and the documentation of these variables.
|
|
;;
|
|
;; NOTE: `ps-lpr-command' and `ps-lpr-switches' take their initial values
|
|
;; from the variables `lpr-command' and `lpr-switches'. If you have
|
|
;; `lpr-command' set to invoke a pretty-printer such as `enscript',
|
|
;; then ps-print won't work properly. `ps-lpr-command' must name
|
|
;; a program that does not format the files it prints.
|
|
;;
|
|
;;
|
|
;; The Page Layout
|
|
;; ---------------
|
|
;;
|
|
;; All dimensions are floats in PostScript points.
|
|
;; 1 inch == 2.54 cm == 72 points
|
|
;; 1 cm == (/ 1 2.54) inch == (/ 72 2.54) points
|
|
;;
|
|
;; The variable `ps-paper-type' determines the size of paper ps-print
|
|
;; formats for; it should contain one of the symbols:
|
|
;; `a4' `a3' `letter' `legal' `letter-small' `tabloid'
|
|
;; `ledger' `statement' `executive' `a4small' `b4' `b5'
|
|
;;
|
|
;; The variable `ps-landscape-mode' determines the orientation
|
|
;; of the printing on the page:
|
|
;; nil means `portrait' mode, non-nil means `landscape' mode.
|
|
;; There is no oblique mode yet, though this is easy to do in ps.
|
|
|
|
;; In landscape mode, the text is NOT scaled: you may print 70 lines
|
|
;; in portrait mode and only 50 lignes in landscape mode.
|
|
;; The margins represent margins in the printed paper:
|
|
;; the top margin is the margin between the top of the page
|
|
;; and the printed header, whatever the orientation is.
|
|
;;
|
|
;; The variable `ps-number-of-columns' determines the number of columns
|
|
;; both in landscape and portrait mode.
|
|
;; You can use:
|
|
;; - (the standard) one column portrait mode
|
|
;; - (my favorite) two columns landscape mode (which spares trees)
|
|
;; but also
|
|
;; - one column landscape mode for files with very long lines.
|
|
;; - multi-column portrait or landscape mode
|
|
;;
|
|
;;
|
|
;; Horizontal layout
|
|
;; -----------------
|
|
;;
|
|
;; The horizontal layout is determined by the variables
|
|
;; `ps-left-margin' `ps-inter-column' `ps-right-margin'
|
|
;; as follows:
|
|
;;
|
|
;; ------------------------------------------
|
|
;; | | | | | | | |
|
|
;; | lm | text | ic | text | ic | text | rm |
|
|
;; | | | | | | | |
|
|
;; ------------------------------------------
|
|
;;
|
|
;; If `ps-number-of-columns' is 1, `ps-inter-column' is not relevant.
|
|
;; Usually, lm = rm > 0 and ic = lm
|
|
;; If (ic < 0), the text of adjacent columns can overlap.
|
|
;;
|
|
;;
|
|
;; Vertical layout
|
|
;; ---------------
|
|
;;
|
|
;; The vertical layout is determined by the variables
|
|
;; `ps-bottom-margin' `ps-top-margin' `ps-header-offset'
|
|
;; as follows:
|
|
;;
|
|
;; |--------| |--------|
|
|
;; | tm | | tm |
|
|
;; |--------| |--------|
|
|
;; | header | | |
|
|
;; |--------| | |
|
|
;; | ho | | |
|
|
;; |--------| or | text |
|
|
;; | | | |
|
|
;; | text | | |
|
|
;; | | | |
|
|
;; |--------| |--------|
|
|
;; | bm | | bm |
|
|
;; |--------| |--------|
|
|
;;
|
|
;; If `ps-print-header' is nil, `ps-header-offset' is not relevant.
|
|
;; The margins represent margins in the printed paper:
|
|
;; the top margin is the margin between the top of the page
|
|
;; and the printed header, whatever the orientation is.
|
|
;;
|
|
;;
|
|
;; Headers
|
|
;; -------
|
|
;;
|
|
;; Ps-print can print headers at the top of each column; the default
|
|
;; headers contain the following four items: on the left, the name of
|
|
;; the buffer and, if the buffer is visiting a file, the file's
|
|
;; directory; on the right, the page number and date of printing.
|
|
;; The default headers look something like this:
|
|
;;
|
|
;; ps-print.el 1/21
|
|
;; /home/jct/emacs-lisp/ps/new 94/12/31
|
|
;;
|
|
;; When printing on duplex printers, left and right are reversed so
|
|
;; that the page numbers are toward the outside (cf. `ps-spool-duplex').
|
|
;;
|
|
;; Headers are configurable:
|
|
;; To turn them off completely, set `ps-print-header' to nil.
|
|
;; To turn off the header's gaudy framing box,
|
|
;; set `ps-print-header-frame' to nil.
|
|
;;
|
|
;; The font family and size of text in the header are determined
|
|
;; by the variables `ps-header-font-family', `ps-header-font-size' and
|
|
;; `ps-header-title-font-size' (see below).
|
|
;;
|
|
;; The variable `ps-header-line-pad' determines the portion of a header
|
|
;; title line height to insert between the header frame and the text
|
|
;; it contains, both in the vertical and horizontal directions:
|
|
;; .5 means half a line.
|
|
|
|
;; Page numbers are printed in `n/m' format, indicating page n of m pages;
|
|
;; to omit the total page count and just print the page number,
|
|
;; set `ps-show-n-of-n' to nil.
|
|
;;
|
|
;; The amount of information in the header can be changed by changing
|
|
;; the number of lines. To show less, set `ps-header-lines' to 1, and
|
|
;; the header will show only the buffer name and page number. To show
|
|
;; more, set `ps-header-lines' to 3, and the header will show the time of
|
|
;; printing below the date.
|
|
;;
|
|
;; To change the content of the headers, change the variables
|
|
;; `ps-left-header' and `ps-right-header'.
|
|
;; These variables are lists, specifying top-to-bottom the text
|
|
;; to display on the left or right side of the header.
|
|
;; Each element of the list should be a string or a symbol.
|
|
;; Strings are inserted directly into the PostScript arrays,
|
|
;; and should contain the PostScript string delimiters '(' and ')'.
|
|
;;
|
|
;; Symbols in the header format lists can either represent functions
|
|
;; or variables. Functions are called, and should return a string to
|
|
;; show in the header. Variables should contain strings to display in
|
|
;; the header. In either case, function or variable, the PostScript
|
|
;; string delimiters are added by ps-print, and should not be part of
|
|
;; the returned value.
|
|
;;
|
|
;; Here's an example: say we want the left header to display the text
|
|
;;
|
|
;; Moe
|
|
;; Larry
|
|
;; Curly
|
|
;;
|
|
;; where we have a function to return "Moe"
|
|
;;
|
|
;; (defun moe-func ()
|
|
;; "Moe")
|
|
;;
|
|
;; a variable specifying "Larry"
|
|
;;
|
|
;; (setq larry-var "Larry")
|
|
;;
|
|
;; and a literal for "Curly". Here's how `ps-left-header' should be
|
|
;; set:
|
|
;;
|
|
;; (setq ps-left-header (list 'moe-func 'larry-var "(Curly)"))
|
|
;;
|
|
;; Note that Curly has the PostScript string delimiters inside his
|
|
;; quotes -- those aren't misplaced lisp delimiters!
|
|
;; Without them, PostScript would attempt to call the undefined
|
|
;; function Curly, which would result in a PostScript error.
|
|
;; Since most printers don't report PostScript errors except by
|
|
;; aborting the print job, this kind of error can be hard to track down.
|
|
;; Consider yourself warned!
|
|
;;
|
|
;;
|
|
;; Duplex Printers
|
|
;; ---------------
|
|
;;
|
|
;; If you have a duplex-capable printer (one that prints both sides of
|
|
;; the paper), set `ps-spool-duplex' to t.
|
|
;; Ps-print will insert blank pages to make sure each buffer starts
|
|
;; on the correct side of the paper.
|
|
;; Don't forget to set `ps-lpr-switches' to select duplex printing
|
|
;; for your printer.
|
|
;;
|
|
;;
|
|
;; Font managing
|
|
;; -------------
|
|
;;
|
|
;; Ps-print now knows rather precisely some fonts:
|
|
;; the variable `ps-font-info-database' contains information
|
|
;; for a list of font families (currently mainly `Courier' `Helvetica'
|
|
;; `Times' `Palatino' `Helvetica-Narrow' `NewCenturySchlbk').
|
|
;; Each font family contains the font names for standard, bold, italic
|
|
;; and bold-italic characters, a reference size (usually 10) and the
|
|
;; corresponding line height, width of a space and average character width.
|
|
;;
|
|
;; The variable `ps-font-family' determines which font family
|
|
;; is to be used for ordinary text.
|
|
;; If its value does not correspond to a known font family,
|
|
;; an error message is printed into the `*Messages*' buffer,
|
|
;; which lists the currently available font families.
|
|
;;
|
|
;; The variable `ps-font-size' determines the size (in points)
|
|
;; of the font for ordinary text, when generating Postscript.
|
|
;; Its value is a float.
|
|
;;
|
|
;; Similarly, the variable `ps-header-font-family' determines
|
|
;; which font family is to be used for text in the header.
|
|
;; The variable `ps-header-font-size' determines the font size,
|
|
;; in points, for text in the header.
|
|
;; The variable `ps-header-title-font-size' determines the font size,
|
|
;; in points, for the top line of text in the header.
|
|
;;
|
|
;;
|
|
;; Adding a new font family
|
|
;; ------------------------
|
|
;;
|
|
;; To use a new font family, you MUST first teach ps-print
|
|
;; this font, ie add its information to `ps-font-info-database',
|
|
;; otherwise ps-print cannot correctly place line and page breaks.
|
|
;;
|
|
;; For example, assuming `Helvetica' is unkown,
|
|
;; you first need to do the following ONLY ONCE:
|
|
;;
|
|
;; - create a new buffer
|
|
;; - generate the PostScript image to a file (C-u M-x ps-print-buffer)
|
|
;; - open this file and find the line:
|
|
;; `% 3 cm 20 cm moveto 10 /Courier ReportFontInfo showpage'
|
|
;; - delete the leading `%' (which is the Postscript comment character)
|
|
;; - replace in this line `Courier' by the new font (say `Helvetica')
|
|
;; to get the line:
|
|
;; `3 cm 20 cm moveto 10 /Helvetica ReportFontInfo showpage'
|
|
;; - send this file to the printer (or to ghostscript).
|
|
;; You should read the following on the output page:
|
|
;;
|
|
;; For Helvetica 10 point, the line height is 11.56, the space width is 2.78
|
|
;; and a crude estimate of average character width is 5.09243
|
|
;;
|
|
;; - Add these values to the `ps-font-info-database':
|
|
;; (setq ps-font-info-database
|
|
;; (append
|
|
;; '((Helvetica ; the family name
|
|
;; "Helvetica" "Helvetica-Bold" "Helvetica-Oblique" "Helvetica-BoldOblique"
|
|
;; 10.0 11.56 2.78 5.09243))
|
|
;; ps-font-info-database))
|
|
;; - Now you can use this font family with any size:
|
|
;; (setq ps-font-family 'Helvetica)
|
|
;; - if you want to use this family in another emacs session, you must
|
|
;; put into your `~/.emacs':
|
|
;; (require 'ps-print)
|
|
;; (setq ps-font-info-database (append ...)))
|
|
;; if you don't want to load ps-print, you have to copy the whole value:
|
|
;; (setq ps-font-info-database '(<your stuff> <the standard stuff>))
|
|
;; or, if you can wait until the `ps-print-hook' is implemented, do:
|
|
;; (add-hook 'ps-print-hook '(setq ps-font-info-database (append ...)))
|
|
;; This does not work yet, since there is no `ps-print-hook' yet.
|
|
;;
|
|
;; You can create new `mixed' font families like:
|
|
;; (my-mixed-family
|
|
;; "Courier-Bold" "Helvetica"
|
|
;; "Zapf-Chancery-MediumItalic" "NewCenturySchlbk-BoldItalic"
|
|
;; 10.0 10.55 6.0 6.0)
|
|
;; Now you can use your new font family with any size:
|
|
;; (setq ps-font-family 'my-mixed-family)
|
|
;;
|
|
;; You can get information on all the fonts resident in YOUR printer
|
|
;; by uncommenting the line:
|
|
;; % 3 cm 20 cm moveto ReportAllFontInfo showpage
|
|
;;
|
|
;; The postscript file should be sent to YOUR postscript printer.
|
|
;; If you send it to ghostscript or to another postscript printer,
|
|
;; you may get slightly different results.
|
|
;; Anyway, as ghostscript fonts are autoload, you won't get
|
|
;; much font info.
|
|
;;
|
|
;;
|
|
;; How Ps-Print Deals With Faces
|
|
;; -----------------------------
|
|
;;
|
|
;; The ps-print-*-with-faces commands attempt to determine which faces
|
|
;; should be printed in bold or italic, but their guesses aren't
|
|
;; always right. For example, you might want to map colors into faces
|
|
;; so that blue faces print in bold, and red faces in italic.
|
|
;;
|
|
;; It is possible to force ps-print to consider specific faces bold or
|
|
;; italic, no matter what font they are displayed in, by setting the
|
|
;; variables `ps-bold-faces' and `ps-italic-faces'. These variables
|
|
;; contain lists of faces that ps-print should consider bold or
|
|
;; italic; to set them, put code like the following into your .emacs
|
|
;; file:
|
|
;;
|
|
;; (setq ps-bold-faces '(my-blue-face))
|
|
;; (setq ps-italic-faces '(my-red-face))
|
|
;;
|
|
;; Faces like bold-italic that are both bold and italic should go in
|
|
;; *both* lists.
|
|
;;
|
|
;; Ps-print keeps internal lists of which fonts are bold and which are
|
|
;; italic; these lists are built the first time you invoke ps-print.
|
|
;; For the sake of efficiency, the lists are built only once; the same
|
|
;; lists are referred in later invocations of ps-print.
|
|
;;
|
|
;; Because these lists are built only once, it's possible for them to
|
|
;; get out of sync, if a face changes, or if new faces are added. To
|
|
;; get the lists back in sync, you can set the variable
|
|
;; `ps-build-face-reference' to t, and the lists will be rebuilt the
|
|
;; next time ps-print is invoked.
|
|
;;
|
|

|
|
;; How Ps-Print Deals With Color
|
|
;; -----------------------------
|
|
;;
|
|
;; Ps-print detects faces with foreground and background colors
|
|
;; defined and embeds color information in the PostScript image.
|
|
;; The default foreground and background colors are defined by the
|
|
;; variables `ps-default-fg' and `ps-default-bg'.
|
|
;; On black-and-white printers, colors are displayed in grayscale.
|
|
;; To turn off color output, set `ps-print-color-p' to nil.
|
|
;;
|
|
;;
|
|
;; Utilities
|
|
;; ---------
|
|
;;
|
|
;; Some tools are provided to help you customize your font setup.
|
|
;;
|
|
;; `ps-setup' returns (some part of) the current setup.
|
|
;;
|
|
;; To avoid wrapping too many lines, you may want to adjust the
|
|
;; left and right margins and the font size. On UN*X systems, do:
|
|
;; pr -t file | awk '{printf "%3d %s\n", length($0), $0}' | sort -r | head
|
|
;; to determine the longest lines of your file.
|
|
;; Then, the command `ps-line-lengths' will give you the correspondance
|
|
;; between a line length (number of characters) and the maximum font
|
|
;; size which doesn't wrap such a line with the current ps-print setup.
|
|
;;
|
|
;; The commands `ps-nb-pages-buffer' and `ps-nb-pages-region' display
|
|
;; the correspondance between a number of pages and the maximum font
|
|
;; size which allow the number of lines of the current buffer or of
|
|
;; its current region to fit in this number of pages.
|
|
;; Note: line folding is not taken into account in this process
|
|
;; and could change the results.
|
|
;;
|
|
;;
|
|
;; New since version 1.5
|
|
;; ---------------------
|
|
;;
|
|
;; Color output capability.
|
|
;; Automatic detection of font attributes (bold, italic).
|
|
;; Configurable headers with page numbers.
|
|
;; Slightly faster.
|
|
;; Support for different paper sizes.
|
|
;; Better conformance to PostScript Document Structure Conventions.
|
|
;;

|
|
;; Known bugs and limitations of ps-print:
|
|
;; --------------------------------------
|
|
;;
|
|
;; Although color printing will work in XEmacs 19.12, it doesn't work
|
|
;; well; in particular, bold or italic fonts don't print in the right
|
|
;; background color.
|
|
;;
|
|
;; Invisible properties aren't correctly ignored in XEmacs 19.12.
|
|
;;
|
|
;; Automatic font-attribute detection doesn't work well, especially
|
|
;; with hilit19 and older versions of get-create-face. Users having
|
|
;; problems with auto-font detection should use the lists
|
|
;; `ps-italic-faces' and `ps-bold-faces' and/or turn off automatic
|
|
;; detection by setting `ps-auto-font-detect' to nil.
|
|
;;
|
|
;; Automatic font-attribute detection doesn't work with XEmacs 19.12
|
|
;; in tty mode; use the lists `ps-italic-faces' and `ps-bold-faces'
|
|
;; instead.
|
|
;;
|
|
;; Still too slow; could use some hand-optimization.
|
|
;;
|
|
;; ASCII Control characters other than tab, linefeed and pagefeed are
|
|
;; not handled.
|
|
;;
|
|
;; Default background color isn't working.
|
|
;;
|
|
;; Faces are always treated as opaque.
|
|
;;
|
|
;; Epoch and Emacs 18 not supported. At all.
|
|
;;
|
|
;; Fixed-pitch fonts work better for line folding, but are not required.
|
|
;;
|
|
;; `ps-nb-pages-buffer' and `ps-nb-pages-region' don't take care
|
|
;; of folding lines.
|
|
;;
|
|
;;
|
|
;; Things to change:
|
|
;; ----------------
|
|
;;
|
|
;; Add `ps-print-hook' (I don't know how to do that (yet!)).
|
|
;; Add 4-up capability (really needed?).
|
|
;; Add line numbers (should not be too hard).
|
|
;; Add `ps-non-bold-faces' and `ps-non-italic-faces' (should be easy).
|
|
;; Put one header per page over the columns (easy but needed?).
|
|
;; Improve the memory management for big files (hard?).
|
|
;; `ps-nb-pages-buffer' and `ps-nb-pages-region' should take care
|
|
;; of folding lines.
