wp2x - A WordPerfect 5.0 to whatever converter

wp2x [ -s ] [ -v ] [ -nblip ] configfile wpfile

Wp2x is intended to convert simple files stored in WordPerfect 5.1 format into any other document processing language that uses plain text files. Examples include TeX, LaTeX, troff, GML and HTML. For a quick result without manual configuration you can try the following command to convert a WP file into HTML: wp2x html foo.wp > foo.html.

Wp2x reads a configuration file and a WordPerfect 5.1 input file, and uses the information in them to produce an output file, which is sent to stdout. If the configuration file cannot be found, a suffix of .cfg is appended. The current directory is searched, as well as the lib directory specified by the WP2X_DIR variable in the Makefile. (Usually /usr/local/lib/wp2x ) and the directories specified by the environment variables PATH , DPATH , and WP2XLIB .


Some codes are not translated because documents that require these codes typically would require significant hand-editing. Hence, there's no point in trying to emulate something you're going to delete anyway. (Remember, wp2x is not intended to be used as an automated conversion program. Rather, it is intended to be used as a single step in the document conversion process, which gets most of the the grunt work of conversion done and out of the way, so that you can concentrate your efforts on converting the trickier parts of the document. The object of the game is to produce a readable conversion, rather than a perfect conversion.)

As the program runs, a dot is printed to stderr for every 1024 characters converted. This can be suppressed with the -s switch, and the interval between dots can be changed with the -n switch.

Suppresses all non-error output to stderr, including the typeout banner, the progress dots, and warnings about undefined expansions.
Every blip tokens, a dot is emitted to stderr, unless the -s switch is given. The value blip must appear immediately following the -n without an intervening space. If no -n switch is supplied, then a value of 1024 is assumed.
prints the version number and the program usage.

The configuration file controls how the file is converted from WordPerfect 5.1 format. Each line of the configuration file is of the form


identifier="list of codes"


where the list of codes is a string which will be placed in the output stream whenever the corresponding WordPerfect code is encountered. Standard C-style backslash-escape sequences are recognized, as well as \xFF for hex values. You do not have to backslash-protect a newline. Some identifiers supply replaceable parameters, which can be interpolated as follows:

%1
interpolate first parameter as a decimal integer.
%2
interpolate second parameter as a decimal integer.
%c
interpolate first parameter as an ASCII character.
%\n
interpolate a newline if the most-recently-output character was not already a newline. (The \n can be either the C-style escape sequence, or an actual newline character.) Use this if the expansion must take place at the beginning of a line. (For example, troff control characters must appear as the first character in the line in order to take effect.) This sequence is meaningful only at the beginning of the string; if it appears elsewhere, it is flagged as erroneous.
%%
interpolate a percent-sign.

A percent sign followed by any other character is considered an error. It is also an error to interpolate a parameter that is not applicable to the identifier being defined. You may interpolate the parameters as many times as, and in whatever order, you wish. (With the exception of the %\n code.)

Here follows a list of the accepted identifiers. In the discussion, `%1' represents the first parameter, and `%2' the second. Remember that the character version of %1 is available as `%c'.

Expanded at the beginning of the file.
Expanded at the end of the file.
Expanded when wp2x needs to insert a comment into the output. The comment is passed as %s.

Insert current page number
Set page number to %1, and set roman-numeral mode
Set page number to %1, and set arabic-numeral mode

What to do when you see a tab character.
Emitted when tab settings are about to change. The BeginTabs code should delete all existing tabs and prepare for new tab settings to start. All tab values are given in columns measured from the physical left edge of the paper. (Not from the left margin.)
Set a normal (left-justified) tabstop at column %1.
Set a centered tabstop at column %1.
Set a right-justified tabstop at column %1.
Set a decimal tab at column %1.
Finish the setting of tabstops.

For example, if the WordPerfect file contains a code that says `Set new tabstops as follows: Regular tab at column 15, a centered tab at column 40, a right-justified tab at column 59, and a regular tab at column 60', then the following expansions are made in succession:



    BeginTabs


    SetTab(15)


    SetTabCenter(40)


    SetTabright(59)


    SetTab(60)


    EndTabs
Hard (nonbreakable) space.
Hard page break.
Force a new page if fewer than %1 half-lines remain on current page.

Hard return.
Soft return.

-
Breakable hyphen.
--
Breakable hyphen, appearing at the end of a line.
=
Non-breakable hyphen.
\-
Discretionary hyphen.
\--
Discretionary hyphen, appearing at the end of a line.

Set left margin at %1 characters and right margin at %2 characters.
Set top margin to %1 lines.
Set page length to %1 lines.

Single spacing.
Double spacing.
1.5S
One-and-a-half spacing.
Triple spacing.
Other line spacing. %1 is twice the desired spacing. (For example, a request for 2.5-spacing sets %1=5.)
Set %1 lines per inch (%1 is either 6 or 8)

Begin header text
End header text
Begin footer text
End footer text

Suppress page number/header/footer information for one page. %1 argument is a bit field which describes what sort of suppression is desired. Here's what the bits mean: 


          1 = all


          2 = page number


          4 = page numbers moved to bottom


          8 = all headers


         16 = header a


         32 = header b


         64 = footer a


        128 = footer b
Center page vertically

Change pitch or font. %1 is the desired pitch. (Negative means proportionally-spaced.) %2 is the font number.
Select paper bin to %1 = 0, 1, ...

No page numbering.
Page number in top left.
Page number in top center.
Page number in top right.
Page number on top outside corners (even/odd).
Page number in lower left.
Page number in bottom center.
Page number in lower right.
Page number on bottom outside corners (even/odd).

If no expansion is supplied for an identifier, then nothing is emitted to stdout, but a warning message is sent to stderr. This warning message will appear at most once per identifier, and it can be suppressed completely by the -s option.

The special identifier typeout causes its replacement text to be displayed on the screen every time the configuration file is read. This is useful for identification messages, or reminders to the user.

A special identifier is any character enclosed in single quotation marks, which represent themselves. For example,



   'α'="{\\alpha}"
causes the string "{\alpha}" to be emitted when an α is encountered. This could also have been written as 


   '\xE0'="{\\alpha}"
if the character α has ASCII value 0xE0. (Which is true for the IBM PC encoding.)

If no definition exists for a particular special character, it is transmitted undisturbed. If a special character is encountered from the upper half of the ASCII character set, and if it has no definition, then a warning message is also emitted. (Which can be suppressed with the -s option.)

Lines beginning with the # character are comments.

This is based on an original WP 4.2 to anything translator. The file format has changed a lot between 4.2 and 5.0. This translator no longer reads WP 4.2 files, although it could be extended to do so.

The 5.0+ format starts with a standard header file. There is a four byte magic number at the head of the file, followed by various product and version information. All WordPerfect Corporation utilities use this standard header. See the WPproducts array in wp2x.c

Once the contents of the file have been located, there are three kinds of codes: simple one byte controls (WP 4.2 had only these kinds), fixed length controls, and variable length controls. There are a large number of undefined types defined for future use. If wp2x detects something it doesn't understand, it can extract the length and skip that code. There are a number of defined codes that are unimplemented. Please see the code, specifically tokens.c where much of the input processing is done.

The sample configuration files in /usr/local/lib/wp2x give you some sort of idea what a `production quality' configuration file might look like. They are not intended to be used as-is, but rather are meant to be modified to suit your particular needs.

Indicates that an unimplemented single byte code was ignored.
Indicates that an unimplemented fixed length code was ignored.
Indicates that an unimplemented variable length code was ignored, and gives its length.
something is wrong in the input file at byte YYYY.
A WP code for which no expansion was defined in the config file was encountered.
An error occurred while processing an expansion escape (%x substitution). Probably it was not a recognized escape, check the config file.
Something is wrong with the input file, a fixed length block was screwed up.
Something that WPC defined as reserved was seen. Check with WPC for new meaning.
magic number. Maybe this is a 4.2 file, or not a WordPerfect file at all?
The file X could not be opened, for the indicated reason.
Inside a string, you typed the characters `\x', but the next character was not a valid hex digit.
The configuration file contained too many strings. Increase the value of POOL_SIZE and recompile.
The word X was encountered in the configuration file when wp2x expected a token identifier like `HRt'. Most likely, you either misspelled it, or you got your quotation marks out of sync.
After an identifier must come an equals-sign.
After the equals-sign must come a quotation mark.
The expansion for the identifier X contained the indicated sequence of characters somewhere other than the beginning of the string. The `%\n' interpolation code is meaningful only at the beginning of a string.
The expansion for the identifier X contained an invalid escape. Either you used `%1', `%2' or `%c' when the identifier X does not supply that parameter, or you meant for a genuine percent sign to be output, in which case you should put `%%' in the expansion.
Character identifiers can only be one character long (after backslash interpretation).
The program expected the next byte from the WP file to be XX, but the byte YY was encountered instead. This means either that your WP file is damaged, or that the program is seriously confused. (Or both.) The program will pretend that the byte in the file was indeed XX, which may lead to synchronization errors later on.
The WP file contained the token X, but the configuration file did not contain any expansion text for it. A null expansion was assumed.
The WP file contained the character c (hex code XX), but the configuration file did not contain any expansion text for it. The character was emitted unaltered. Beware that this may give your text formatter indigestion if it does not handle eight-bit characters.
The file being converted uses a code which wp2x does not know how to convert. A comment is placed in the output file in its place. If you ever encounter a `WPCorp reserved' or a `WPCorp undefined' code, the author would appreciate hearing from you.
While processing text, wp2x noticed that you used an invalid escape. Nothing is emitted as the escape text. (The internal-ness is that this error is supposed to be caught at the time the configuration file is read.)

Naive configuration files will fail if your WP file doesn't nest its tags properly. A typical case is



     [Center][B]Hello[center]


     [Center]There[b][center]

to produce a centered boldface `Hello'. If you use the naive encoding of



     Center="\\centerline{"


     center="}\n"


     Bold="{\\bf "


     bold="}"

then this will expand to



     \centerline{{\bf Hello}


     \centerline{There}}

WordPerfect has no clean concept of grouping; it lets you change fonts at any time and let those changes propagate outside the current environment. (With the exception of headers, footers, footnotes, and endnotes.)

Now sure, you could write complicated configuration strings to try to handle this `properly', but it'd probably not be worth the trouble. After all, the purpose is not to perform a perfect conversion, but rather to produce a readable conversion, which can then be massaged by hand to produce a perfect manuscript.

Another potential problem is combined attributes, like boldface underline. Under a naive configuration,



     [B]Boldface [U]Underlined boldface[b] Underlined[u] normal.
comes out as 


 {\bf Boldface {\it Underlined boldface} Underlined\/} normal.
which is wrong for two reasons. One is the nesting problem discussed above. The other is that TeX font attributes do not combine.

Similar problems exist for other document preparation systems. So be careful.
