---|
4 | // File: bounty:/archive/src/a2ps/Last/a2ps.c |
---|
5 | // Created: Fri Nov 5 8:20 1993 by miguel@bountyimag.fr (Miguel Santana) |
---|
6 | // Version: 4.3 |
---|
7 | /* */ |
---|
8 | // Edit history: |
---|
9 | // 1) Derived of shell program written by evan@csli (Evan Kirshenbaum). |
---|
10 | // Written in C for improve speed execution and portability. Many |
---|
11 | // improvements have been added. |
---|
12 | // Fixes by Oscar Nierstrasz @ cui.uucp: |
---|
13 | // 2) Fixed incorrect handling of stdin (removed error if no file names) |
---|
14 | // 3) Added start_page variable to eliminate blank pages printed for |
---|
15 | // files that are exactly multiples of 132 lines (e.g., man pages) |
---|
16 | // Modified by santana@imag.fr: |
---|
17 | // 4) Added new options at installation : sheet format (height/width in |
---|
18 | // inches), page format (number of columns per line and of lines per |
---|
19 | // page). |
---|
20 | // Modified by santana@imag.fr: |
---|
21 | // 5) Added new option to print n copies of a same document. |
---|
22 | // 6) Cut long filenames if don't fit in the page header. |
---|
23 | // Modified by Tim Clark (T.Clark@warwick.ac.uk): |
---|
24 | // 7) Two additional modes of printing (portrait and wide format modes) |
---|
25 | // 8) Fixed to cope with filenames which contain a character which must |
---|
26 | // be escaped in a PostScript string. |
---|
27 | // Modified by santana@imag.fr to |
---|
28 | // 9) Added new option to suppress heading printing. |
---|
29 | // 10) Added new option to suppress page surrounding border printing. |
---|
30 | // 11) Added new option to change font size. Lines and columns are |
---|
31 | // automatically adjusted, depending on font size and printing mode |
---|
32 | // 12) Minor changes (best layout, usage message, etc). |
---|
33 | // Modified by tullemans@apolloway.prl.philips.nl |
---|
34 | // 13) Backspaces (^H) are now handled correctly. |
---|
35 | // Modified by Johan Vromans (jv@mh.nl) to |
---|
36 | // 14) Added new option to give a header title that replaces use of |
---|
37 | // filename. |
---|
38 | // Modified by craig.r.stevenson@att.com to |
---|
39 | // 15) Print last modification date/time in header |
---|
40 | // 16) Printing current date/time on left side of footer (optional) |
---|
41 | // Modified by erikt@cs.umu.se: |
---|
42 | // 17) Added lpr support for the BSD version |
---|
43 | // 18) Added som output of pages printed. |
---|
44 | // Modified by wstahw@lso.win.tue.nl: |
---|
45 | // 19) Added option to allowing the printing of 2 files in one sheet |
---|
46 | // Modified by mai@wolfen.cc.uow.oz |
---|
47 | // 20) Added an option to set the lines per page to a specified value. |
---|
48 | // 21) Added support for printing nroff manuals |
---|
49 | // Modified by santana@imag.fr |
---|
50 | // 22) Integration of changes. |
---|
51 | // 23) No more standard header file (printed directly by a2ps). |
---|
52 | // 24) New format for command options. |
---|
53 | // 25) Other minor changes. |
---|
54 | // Modified by Johan Garpendahl (garp@isy.liu.se) and santana@imag.fr: |
---|
55 | // 26) Added 8-bit characters printing as ISO-latin 1 chars |
---|
56 | // Modified by John Interrante (interran@uluru.stanford.edu) and |
---|
57 | // santana@imag.fr: |
---|
58 | // 27) Two pages per physical page in portrait mode |
---|
59 | // Modified by santana@imag.fr: |
---|
60 | // 28) New option for two-sided printing |
---|
61 | // 29) Several fixes |
---|
62 | // Modified by Chris Adamo (adamo@ll.mit.edu) and |
---|
63 | // Larry Barbieri (lbarbieri@ll.mit.edu) 3/12/93 |
---|
64 | // 30) Output format enhancements. |
---|
65 | // 31) Added login_id flag (for SYSV and BSD only) for printing user's |
---|
66 | // login ID at top of page. Added command line parameter (-nL) to |
---|
67 | // suppress this feature. |
---|
68 | // 33) Added filename_footer flag for printing file name at bottom |
---|
69 | // of page. Added command line parameter (-nu) to suppress this |
---|
70 | // feature. |
---|
71 | // 34) Added -B (-nB) options to enable (disable) bold font |
---|
72 | // Modified by santana@imag.fr: |
---|
73 | // 35) Adapted to respect Adobe conventions for page independence. A2ps |
---|
74 | // output can be now used by other Postscript processors. |
---|
75 | // 36) Names of most postscript variables have been coded in order to |
---|
76 | // reduce the size of the output. |
---|
77 | // 37) Ansi C compilers are now automatically taken into account. |
---|
78 | // 38) Enhanced routine for cutting long filenames |
---|
79 | // 39) Added -q option to print files in quiet mode (no summary) |
---|
80 | // 40) Fixed some little bugs (counters, modification time for stdin, |
---|
81 | // character separator when printing line numbers and cutting a |
---|
82 | // line). |
---|
83 | // 41) Some minor changes (new preprocessing variables, formatting) |
