2007-07-25  Ben Pfaff  <blp@gnu.org>

        Allow the user to specify an initialization string to write at the
        beginning of an ASCII output file.
        * ascii.c (struct ascii_driver_ext): New member `init'.
        (ascii_open_driver): Initialize `init'.
        (ascii_close_driver): Parse `init'.
        (ascii_open_page): Write `init' to output file.

        * output.c (get_option_token): Fix parsing of octal constants.

2007-07-25  Ben Pfaff  <blp@gnu.org>

        Make interactive output go to the terminal (bug #17213), by
        causing the UI to flush output to the user when it prompts for a
        command.

        * ascii.c (ascii_open_driver): Move the file open into
        ascii_open_page, so that we can re-open after a flush.
        (ascii_close_driver): Close file using ascii_flush.
        (ascii_open_page): Open the output file if it's not already open.
        Use fn_open so that we can support pipes.
        (ascii_close_page): Do nothing if output file not open.
        (ascii_flush): New function.
        (static var ascii_class): Add ascii_flush.

        * manager.c (som_flush): New function.

        * output.c (outp_flush): New function.

Tue Feb 20 07:03:48 2007  Ben Pfaff  <blp@gnu.org>

        * html.c: Don't need to include "getlogin_r.h" anymore, because
        gnulib merged it into <unistd.h>.

Sun Feb 18 11:20:35 2007  Ben Pfaff  <blp@gnu.org>

        * postscript.c: Add missing _() around message.

Sun Feb 11 17:59:30 2007  Ben Pfaff  <blp@gnu.org>

        * html.c (html_initialise_chart): Mark `this' parameter UNUSED to
        account for NO_CHARTS case.

Sat Feb  3 21:56:46 2007  Ben Pfaff  <blp@gnu.org>

        * table.c (tab_hline): Allow t->nr as y argument, so that we can
        draw a line below the bottom row of the table.

Wed Feb  7 21:38:12 2007  Ben Pfaff  <blp@gnu.org>

        * afm.c: Add #include <limits.h>.  Thanks to John McCabe-Dansted
        <gmatht@gmail.com> for pointing out the need.

Sun Oct  8 07:09:34 WST 2006 John Darrington <john@darrington.wattle.id.au>

        * table.c (tab_destroy): Freed title, since this is not allocated
        from the pool.

        * html.c (html_open_driver): Freed chart_file_name.

Wed Jul 12 21:03:37 2006  Ben Pfaff  <blp@gnu.org>

        * table.c (tab_natural_width): Get rid of warning on empty column,
        which tended to just trigger false positives because we handle
        joined cells so badly.  We need a real fix, and the warning is not
        helpful.

        * table.c (tab_offset): [DEBUGGING] Let row, col arguments be as
        big as row or column count.
        
Wed Jul 12 20:58:19 2006  Ben Pfaff  <blp@gnu.org>

        * output.c (outp_drivers): [DEBUGGING] Delete unused declaration.

Sat Jul  1 17:20:03 2006  Ben Pfaff  <blp@gnu.org>

        Make the destination for charts configurable in the HTML driver.
        Fixes bug #15723, "HTML driver creates .png files insecurely".

        * htmlP.h: (struct html_driver_ext) Add chart_file_name, chart_cnt
        members.
        
        * html.c: (html_open_driver) Initialize new members.
        (option_tab var) Add "chart-files" option.
        (handle_option) Parse "chart-files" option.
        (html_initialise_chart) Name file based on "chart-files" option.
        
Sat Jul  1 22:41:26 2006  Ben Pfaff  <blp@gnu.org>

        Fix bug #16644: Output Driver crashes in DISPLAY VARIABLES.
        
        * table.c (tab_create): Don't allocate t->hrh, t->wrv yet, because
        the table size might change before we're ready to use them.
        (tabi_table) Allocate them here instead.

Fri Jun  9 14:42:35 2006  Ben Pfaff  <blp@gnu.org>

        Reform string library.
        
        * output.c (init_default_drivers): Update call to
        configure_driver() to new interface.
        (get_option_token) Use a modifiable substring in interface instead

        * table.h (struct tab_table): Change title member to char *.

Thu May 25 18:02:53 WST 2006 John Darrington <john@darrington.wattle.id.au>

        * table.c: Removed redundant extern declaration.

Sun May 14 14:03:56 2006  Ben Pfaff  <blp@gnu.org>

        * output.c (outp_eject_page): Always make sure that a page is open
        upon return.

Sun May 14 13:54:58 2006  Ben Pfaff  <blp@gnu.org>

        * postscript.c: (ps_chart_finalise) Fix format of %%EndDocument
        comment, which screwed up gv's idea of where one page ended and
        the next one began.  Thanks to John Darrington for pointing out
        the bug.

Sun Apr 16 11:48:25 2006  Ben Pfaff  <blp@gnu.org>

        Start reforming error message support.  In this phase, we get rid
        of "installation errors" and change all uses of msg() in the
        output drivers to uses of error() or error_at_line().

        * Removed all inclusion of <libpspp/message.h> in this directory.

        * output.c: Changed all uses of msg() to error() or
        error_at_line().
        (outp_read_devices) Maintain line number in int variable instead
        of "struct file_locator".
        (tokener) Renamed get_option_token(), rewritten, changed interface.
        (outp_parse_options) Change `options' argument to type const
        struct string *.  Rewritten.
        (configure_driver) Passes a struct string * to ->open_driver()
        instead of char *.
        (outp_get_paper_size) Maintain line number in int variable instead
        of "struct file_locator".  Removed stupid cache.

        * output.h: (struct outp_class) Change `open_driver' function to
        take const struct string * instead of const char *.  Updated all
        implementations.

Mon Apr  3 11:14:38 2006  Ben Pfaff  <blp@gnu.org>

        Rewrite a lot of the output drivers and infrastructure.
        Started transitioning from msg() to error().
        Vertical rules in tables now default to putting a small gap
        between columns, instead of no gap or rule at all.
        See NEWS for user-visible changes.

        * automake.mk: (output_sources) Add afm.c, afm.h.  Remove font.h,

        (configure_driver) Changed args from `const char *'s to `const
        struct string *'s.  Rewrote.  Don't call ->open_global().  Now
        just calls ->open_driver() instead of ->preopen_driver(),
        ->option(), ->postopen_driver().
        (configure_driver_line) Adapt to new configure_driver() interface.
        (destroy_driver) Don't call ->close_global().
        (option_cmp) Removed.

        and OUTP_EMPHASIS.
        (struct outp_text) Replaced `options' member by `font' and
        `justification'.  Renamed `s' to `string'.  Removed `w', `l'.
        Updated all usages.
        (struct outp_class) Removed `magic', `open_global',
        `close_global', `font_sizes', `preopen_driver', `option',

        `text_draw' members.  Updated all usages.
        (struct outp_driver) Rearranged members.  Removed `driver_open',
        `res', `horiz', `vert', `horiz_line_spacing', `vert_line_spacing'
        members.
        (struct outp_option_info) Removed.
        (struct outp_driver_class_list) Removed.
        (outp_match_keyword) Changed interface.

        * table.c: (tab_create) Now ignores reallocable argument: tables
        can always be reallocated.  Use pool_create_container().
        Initialize vertical rules to UCHAR_MAX.
        (options_to_font) New function.
        (tab_destroy) Remove futile assignment.
        (tab_realloc) Initialize vertical rules to UCHAR_MAX.

        have ->trh or ->trv.  Implement new default for vertical rules.
        (render_rows) New function.
        (tabi_render) Rewrite in terms of render_rows() for clarity.
        (translate_justification) New function.

        no title.

Sat Mar  4 13:48:16 2006  Ben Pfaff  <blp@gnu.org>

        We didn't provide a way to define these macros, so obviously
        there's little demand for them.

        * html.c: Don't test for NO_HTML.

        * postscript.c: Don't test for NO_POSTSCRIPT.

        * output.c: Don't test for either of those.
