Enhancements | Fixes | Incompatibilities
There are lots of new things in this version. The general enhancements are:
The table enhancements are:
The page formatting enhancements are:
The configuration enhancements are:
Details are given below.
Enumerated values no longer need to be quoted. In a set of name-value pairs, if an expression is a single word where:
then the word is assumed to be an enemerated value and it is automatically converted to a string. For example, the following two lines are now equivalent:
P1[align="Center"] My Title P1[align=Center] My Title
The overall appearance (i.e. look) of an SDF document can be controlled via the -k option or the OPT_LOOK variable. SDF now supports the following looks:
SDF now supports the styles (i.e. document types) below.
Style | Purpose |
General: | |
document | a normal document |
manual | a manual |
paper | a technical paper |
Administration: | |
admin | generic administration document |
fax | a fascimile |
memo | a memorandum |
newslttr | a newsletter |
minutes | minutes of a meeting |
Miscellaneous: | |
listing | a source code listing |
The build_title macro is used to build the cover page for the general styles. The title filter is used to build the title block for the administation styles. The miscellaneous styles do not have a title.
Adding new styles for a look is now much easier than it was previously. Furthermore, manual is now just another style rather than a special mode.
build_title now supports the following variable:
Supported DOC_COVER values and their meanings are given below:
Value | Meaning |
original | SDF's original cover page layout |
project | a cover page useful for project documentation |
manual | the cover page used when OPT_STYLE is manual |
paper | the cover page used when OPT_STYLE is paper |
The manual cover supports a new macro called DOC_OFFICES, i.e. if DOC_OFFICES is defined, its contents are appended after the inside cover page.
The SDF What's Planned document and bugs.html have been replaced by the SDF Bug Database. In fact, the organisation of the documentation has been improved quite a bit.
Any document can now be converted to a FrameMaker book, i.e. it is no longer necessary to specially organise files in order to create a FrameMaker book.
Tables of style columns (the default) now have a thin line above group rows.
Tables can now be specified as list items by using the listitem parameter of the table filter. The value is the logical indent of the list (e.g. 1, 2, etc.). When generating HTML which contains a table within a numbered list, the listitem parameter is necessary in order to prevent the numbering from resetting.
The new box filter can be used to place a box around one or more lines of text.
The new center filter can be used to center a region of text.
The new paragraph attribute called wide can be used to specify that a paragraph straddles the side-head area in addition to the main text area. Likewise. class filters (e.g. terms, references, etc.) now also support the wide attribute.
By default, SDF automatically generates an id attribute for all headings in the table of contents. However, it is occasionally necessary to disable this, particularly when the same heading appears multiple times in a file. The new paragraph attribute noid can be used to prevent an id being generated for a paragraph.
The title for an administration-style document can now be changed by either setting the DOC_TYPE variable or by using the new type parameter to the title filter. For example, if you want the title "Urgent Memo" rather than the default "MEMORANDUM" for a memo, you can now do the following:
!init OPT_STYLE="memo" !block title; type="Urgent Memo" usual name-values pairs go here ... !endblock
The title filter now also supports a format parameter which can be used to tune the column widths, when necessary.
RTF can now be generated via FrameMaker by using the new sdf2fmrtf alias, i.e. the command is (say):
sdf -2fmrtf myfile.sdf
When RTF is generated via FrameMaker, Word's standard style names are used, where possible. This makes it easier to import the RTF file into an existing Word document.
Lists of tables and lists of figures can now be generated for normal documents, i.e. it is no longer necessary to use a FrameMaker book to build these lists.
The new variable TXT_MARGIN can be used to control the width for txt output. Likewise, the new variable POD_MARGIN can be used to control the width of tables for pod format.
The new bugtrack module can be used to build a simple bug tracking system like SDF's bug database.
The new namevalues macro can be used to output a set of name-value pairs for an object. The parameters are:
For example:
!namevalues 'bugs'; 'sd0001'; 'Priority,Status,Type'
Finer control over object catalog formatting is now available via the new style and headings attributes. style is the table style to use. The default value is plain. If headings is set, column headings are output. (By default, they are not.)
SDF now supports dynamic column widths for paper documentation, i.e. if a width is not specified for a column, then the column is sized based on the text within it and the space available. Proportional column widths are also supported.
The format attribute of the table filter is either:
Examples of the column width specifications now supported are given below.
Value | Meaning |
30pt | an exact size (other supported units are cm, mm, " and in) |
30% | a percentage of the size available |
30 | a percentage of the size available (% is implicit) |
10-20 | dynamic size between 10% and 20% of the total width |
-20 | dynamic size between 0% and 20% of the total width |
10- | dynamic size between 10% and 100% of the total width |
- | dynamic size between 0% and 100% of the total width |
3* | 3 units of the remaining space |
* | same as 1* |
For example, in the table below, the second column will be twice the size of the last column.
!block table; format="20,2*,10,*" Name Column2 Column3 Column4 A B C D X Hello dear world Y Z !endblock
The output is:
Name | Column2 | Column3 | Column4 |
A | B | C | D |
X | Hello dear world | Y | Z |
If a column is not given a size, the following rules are used:
For example, the first and third columns in the table below will be dynamically sized. The first column will take as much space as required and the last column will expand so that the table takes the full width of the text area.
!block table; format=",30,,10" Name Column2 Column3 Column4 A B C D X Hello dear world Y Z !endblock
The output is:
Name | Column2 | Column3 | Column4 |
A | B | C | D |
X | Hello dear world | Y | Z |
However, in the example below, each column will only take as much space is required, making the table narrower than it would be otherwise.
!block table; narrow Name Column2 Column3 Column4 A B C D X Hello dear world Y Z !endblock
The output is:
Name | Column2 | Column3 | Column4 |
A | B | C | D |
X | Hello dear world | Y | Z |
If an = character is used in place of a - character for a column width, then those columns will be equalised in size. For example, the second and forth columns in the table below will be made equal in size.
!block table; format="20,5=30,10,=" Name Column2 Column3 Column4 A B C D X Hello dear world Y Z !endblock
The output is:
Name | Column2 | Column3 | Column4 |
A | B | C | D |
X | Hello dear world | Y | Z |
The table filter now supports the following attributes:
If the headings attribute is not defined, then as previously done, the column headings are generated using the column names given on the parsing line. For example, the column headings in the table below will be Name and Age:
!block table Name Age Bill 42 !endblock
Alternatively, if the headings attribute is defined, then that number of data rows are used as the column headings, i.e. the parsing line is not used to build the column headings. For example, the column headings in the table below will be "Title" and Age (remembering that a filter attribute is implicitly given the value 1 is no value is supplied).
!block table; headings A B "Title" Age Bill 42 Sally 23 !endblock
Likewise, the column headings below will be Preferred Title and Likely Age with each heading taking 2 rows.
!block table; headings=2 A B Preferred Likely Title Age Bill 42 Sally 23 !endblock
Collectively, these new attributes improve things in several ways:
The horizontal alignment and vertical placement of a table can be controlled by setting the align and placement parameters of the table filter respectively. The permitted align values are:
Value | Meaning |
Left | left-align the table |
Center | center the table |
Right | right-align the table |
Inner | align the table with the inner margin |
Outer | align the table with the outer margin |
The permitted placement values are:
Value | Meaning |
Float | next column if necessary |
Pagetop | top of the next page |
Columntop | top of the next column |
Lefttop | top of the next left-hand page |
Righttop | top of the next right-hand page |
Tables can now be filtered and sorted by using the new where and sort attributes of the table filter. These attributes are also supported by the class filters (e.g. terms, references). In either case, filtering is done before sorting.
The where attribute takes an expression which is evaluated for each record. Special symbols available are:
Symbol | Meaning |
$_ | the current record |
$o{"xyz"} | the value of column xyz |
sort takes a comma-separated list of column names to sort on. If no columns are specified, the data is sorted using all columns in the order in which they appear. All sorting is done alphabetically - numeric sorting is not supported.
Landscape tables are now supported via the landscape parameter of the table filter. The value is the height allocated to the area in which the table is placed. If a unit is not specified, the value is assumed to be a percentage of the text column height. For convenience, a value of 1 implies a full page table. Some examples are given below.
Value | Meaning |
landscape="50pt" | height allocated to table is 50 points |
landscape="50%" | half page table |
landscape=50 | half page table (% is the default units) |
landscape=1 | full page table (1 implies 100%) |
landscape | full page table (syntactic shorthand for above) |
The colaligns parameter of the table filter can now be used to control the alignment of text within columns of a table. For example:
!block table; colaligns="LCCR" Name Column2 Column3 Column4 A B C 1.0 X Hello dear world Y 10.2 !endblock
The output is:
Name | Column2 | Column3 | Column4 |
A | B | C | 1.0 |
X | Hello dear world | Y | 10.2 |
The value of colaligns is usually a sequence of the letters L, C and R (which mean what one would expect). If you prefer, a comma-separated list of the values Left, Center and Right can be specified. For example:
!block table; colaligns="Left,Center,Center,Right" Name Column2 Column3 Column4 A B C 1.0 X Hello dear world Y 10.2 !endblock
Cells within a table can now be given attributes by preceding the cell value with a semicolon-separated list of name-value pairs enclosed in square brackets. For example:
!block table; colaligns="LCCR" Name Column2 Column3 Column4 A [align=Left]B C [bgcolor=Green]1.0 X Hello dear world Y [bgcolor=Red]10.2 !endblock
The output is:
Name | Column2 | Column3 | Column4 |
A | B | C | 1.0 |
X | Hello dear world | Y | 10.2 |
The cell attributes supported are given below.
Name | Value |
General: | |
align | horizontal alignment (Left, Center, Right) |
valign | vertical alignment (Top, Middle, Bottom, Baseline) |
cols | the number of columns this cell spans (default is 1) |
rows | the number of rows this cell spans (default is 1) |
bgcolor | background colour of cell (see below) |
PS only: | |
fill | background colour fill percentage |
truling | ruling setting for top of cell |
bruling | ruling setting for bottom of cell |
lruling | ruling setting for left of cell |
rruling | ruling setting for right of cell |
angle | angle of text (0, 90, 180, 270) |
HTML only: | |
nowrap | disable word wrap for this cell |
Special: | |
sdf | treat the cell text as SDF (rather than as phrase text) |
tag | phrase tag to apply to cell text |
paratag | paragraph style to apply to cell text |
For PS (i.e. MIF) generation, the supported colour values are Black, White, Red, Green, Blue, Yellow, Cyan and Magenta. If a different colour is specified, it is ignored. The supported fill values are 100, 90, 70, 50, 30, 10 and 3. If a fill value is not specified, 100% fill is used.
For HTML generation, any of the HTML colours names (including those supported for PS generation) or the "#rrggbb" form can be used.
The permitted ruling values are Vthin, Thin, Medium, Thick and Double.
The sdf, tag and paratag attributes control the way in which the cell text is converted to SDF:
tag is usually set via the tags or groups parameters of the table filter.
The spreadsheet expression evaluator and the documentation below was written by Tim Hudson (tjh@cryptsoft.com).
Spreadsheet style calculations have been introduced into SDF using the standard [[ ]] syntax with a prefix of + (or =) indicating that the expression is to be evaluated by the calculation routines.
This extension has been loosely modelled on Microsoft Excel® in terms of the initial functions supported and the syntax used.
Each cell in a table has an cellid which is made up of a single uppercase letter indicating the column index and a number indicating the row index (counting from 1 and excluding the heading rows). The upper left cell is hence A1.
An example grid indicating cellids:
Title1 | Title2 | Title3 | Title4 | Title5 |
A1 | B1 | C1 | D1 | E1 |
A2 | B2 | C2 | D2 | E2 |
A3 | B3 | C3 | D3 | E3 |
... | ... | ... | ... | ... |
A100 | B100 | C100 | D100 | E100 |
A range of cellids is specified using the syntax cellid1:cellid2. For example: A1:C1 is exactly the same as A1,B1,C1
An expression consists of a combination of standard Perl operators and spreadsheet functions and cellids or cellid ranges.
Standard Perl operators include:
Spreadsheet functions use the syntax FUNCTION(ARG1,ARG2,...ARGN).
The following functions are supported:
A simple example:
!block table; style="grid" Count Price Total 10 5 [\[=A1*B1]\] 15 5.23 [\[=ROWPROD]\] [\[=COLSUM]] [\[=B1+B2]\] [\[=COLSUM]\] !endblock
Which generates the result below. (Ok, summing two prices is meaningless, but it illustrates the syntax.)
Count | Price | Total |
10 | 5 | 50.00 |
15 | 5.23 | 78.45 |
25.00 | 10.23 | 128.45 |
A spreadsheet expression will recursively evaluate any expressions contained in cells that are used in an expression. In the example above, the expression in cell C3 depends on the results of the expression in cell C1 and C2.
Generally speaking, SDF can now support arbitrary page sizes. The catch is that the page size must now be specified up front via the OPT_PAGE_SIZE variable on the init line or via sdf's -S option. (Previously, the (no longer supported) DOC_PAGE_SIZE variable could be specified anywhere in the document.)
The supported values of OPT_PAGE_SIZE are given below. The default page size is global.
Name | Width | Height | Comment |
global | 21.0cm | 11.0in | will fit on either A4 or letter |
A3 | 29.7cm | 42.0cm | |
A4 | 21.0cm | 29.7cm | |
A5 | 14.8cm | 21.0cm | |
B4 | 25.7cm | 36.4cm | |
B5 | 17.6cm | 25.0cm | |
letter | 8.5in | 11.0in | |
legal | 8.5in | 14.0in | |
tabloid | 11.0in | 17.0in |
New page sizes can be defined in sdf.ini. A rotated version is also available for each page size. Rotated sizes are named with an appended R. For example, the rotated A4 size is called A4R.
SDF now provides 3 ways of controlling headers and footers:
where:
The meaning of each page type is explained below.
Page | Usage |
FIRST | the first page in the document |
RIGHT | the page used for single-sided documents and the right hand side of double-sided documents |
LEFT | the left hand side of double-sided documents; ignored for single-sided documents |
Supported OPT_HEADINGS values and their meanings are given below:
Value | Meaning |
0 | no header, no footer |
1 | single line header, single line footer |
2 | two line header and two line footer |
3 | two line header and three line footer |
4 | two line header and four line footer |
The following special tags are supported within headers and footers:
Tag | Meaning |
PAGENUM | current page number |
PAGECOUNT | highest page number |
PARATEXT | paragraph text (e.g. Hardware requirements) |
PARANUM | paragraph number (e.g. Appendix A) |
PARANUMONLY | paragraph number only (e.g. A) |
PARASHORT | value of short attribute of paragraph |
PARALAST | text of last paragraph on page with the nominated style |
The PARA* tags require a comma separated list of paragraph styles to be nominated as the text of the phrase, e.g. {{PARATEXT:H1,A1,P1}}.
The PARASHORT tag is useful for placing an alternative heading in a header, say. For example, you might set up your header to include {{PARASHORT:H1}} and have the following text in your document:
H1[short='Getting started'] Getting started with SDF
The PARALAST tag is useful for producing dictionary-like headers.
High level control over header/footer borders is provided by the OPT_BORDERS variable. The supported values and their meanings are given below:
Value | Meaning |
0 | no header/footer borders |
1 | line below header, line above footer |
2 | lines above and below header, line above footer |
Finer control is available by setting the following variables:
Name | Value |
PAGE_page_HEADER_BORDER | border specification string |
PAGE_page_FOOTER_BORDER | border specification string |
where page is either FIRST, RIGHT or LEFT.
A border specification string is a comma-separated list of attributes which collectively describe the border. The format of each attribute is name[=value]. The supported attributes are:
For top, bottom and box, the value of the attribute is the line width in points.
In order to support fancy background images, SDF supports the following variables:
Name | Value |
PAGE_page_BACKGROUND | the logical image name |
where page is either FIRST, RIGHT or LEFT.
When FrameMaker is being used to generate PostScript, the image name is mapped to a master page called backgrnd within a file called backgrnd.mif.
Page margins can now be controlled via the following variables:
Name | Value |
OPT_MARGIN_TOP | size of the margin above the header, if any |
OPT_MARGIN_BOTTOM | size of the margin below the footer, if any |
OPT_MARGIN_INNER | size of the inner margin |
OPT_MARGIN_OUTER | size of the outer margin |
The positioning of headers and footers can now be controlled via the following variables:
Name | Value |
PAGE_page_HEADER_HEIGHT | height of the area allocated to the header |
PAGE_page_HEADER_GAP | size of the gap between the header area and the text area |
PAGE_page_FOOTER_HEIGHT | height of the area allocated to the footer |
PAGE_page_FOOTER_GAP | size of the gap between the text area and the footer area |
where page is either FIRST, RIGHT or LEFT.
After the margins and header/footer are allocated, the remaining text area contains 1 or more text columns and an optional side head. The layout of these is controlled by the following variables:
Name | Value |
OPT_COLUMNS | numbers of text columns |
OPT_COLUMN_GAP | space between columns |
OPT_SIDEHEAD_WIDTH | size allocated to the sidehead |
OPT_SIDEHEAD_GAP | space between the side-head and first text column |
The following read-only variables provide information on the page layout:
Name | Value |
DOC_PAGE_WIDTH | width of page |
DOC_PAGE_HEIGHT | height of page |
DOC_FULL_WIDTH | width of text area including the side-head |
DOC_TEXT_WIDTH | width of text area available for text columns |
DOC_TEXT_HEIGHT | height of text area |
DOC_COLUMN_WIDTH | width of a text column |
All the information variables are in units of points. The text area is the area allocated to text, excluding the header and footer (if any) on the RIGHT page.
When a book is being generated, each component of the book may have its own FIRST, RIGHT and LEFT pages, i.e. all of the macros and variables above support an extended set of page values component_FRL where:
The component names supported are given below.
Name | Meaning |
FRONT | the cover component |
PRETOC | components before the contents |
TOC | the table of contents |
LOF | the list of figures |
LOT | the list of tables |
PRECHAPTER | components before the chapters |
CHAPTER | a normal chapter |
APPENDIX | an appendix |
PREIX | components before the index |
IX | the index |
If a component does not have a component-specific macro/variable defined, then the generic macro/variable is used.
Previously, SDF produced MIF documents by merging generated MIF paragraphs into FrameMaker templates. This approach was easy to implement but maintaining the FrameMaker templates was difficult as every look required several templates for each page size!
FrameMaker templates can still be used but are no longer needed, nor recommended. Instead, the definitions of paragraph styles, phrase styles, table styles and graphic (border) frames is now done via SDF templates. SDF templates have the following advantages:
The new sdtgen command can be used to build an SDF template from a FrameMaker one. Typically, sdtgen is used to create an initial template which is then simplified via definition inheritance and template inheritance.
The following new symbols are now available within event processing for paragraphs:
Symbol | Meaning |
$level | the current heading level (before this paragraph) |
$prev_style | the style of the previous paragraph |
$prev_text | the text of the previous paragraph |
%prev_attr | the attributes of the previous paragraph |
These symbols make it much easier to do some really nice things. For example, the following rule can be used to put level 2 headings on a new page unless the heading is the first one within a chapter:
!on paragraph '[HAP]2';; if ($level != 1) {$attr{'top'} = 1}
Tim Hudson has contributed a number of fixes to this release including:
Other fixes include:
As the default page size is now global rather than A4, page breaks may occur slightly earlier than they previously did. The advantage of changing to global is that documents should now print successfully on US letter paper.
Memos, faxes, minutes and newsletters no longer have the company address in the top right hand corner. (I'll fix this soon, but it is not a high priority at the moment.)
As txt and pod outputs use a different algorithm for deciding column widths when a table does not have a format parameter, some table cells may no longer fit when these output formats are used.
The table attribute previously called headings has been renamed to parseline to better reflect its purpose and to make way for the new meaning.
The DOC_TOCTEXT variable has been renamed to DOC_TOC_TITLE. The DOC_TOCGRAPHIC variable has been renamed to DOC_TOC_GRAPHIC.
The newsletter style has been renamed to newslttr.
overhead is now a look, rather than a style. The overhead look is untested and rarely used, so use it at your own risk.
The aliases sdf2htmls and sdf2txts have been renamed to sdf2fmhtml and sdf2fmtxt respectively.
/usr/local/bin/perl5 is now the default perl interpreter used.
