ddiftext(1) General Commands Manual ddiftext(1) NAME ddiftext - convert DDIF formatted files to text formatted files SYNOPSIS ddiftext [-m message_log] [-O optionfile] [-o outputfile] [-p op- tions_line]... [-d extension] [inputfile [outputfile [logfile]]] OPTIONS Enables enhanced messaging and logs all messages to message_log or, if `-' is specified, to the standard error in place of the message_log. If you do not specify this option, only serious errors are reported. Specifies the name of the options file containing options for this con- verter. The options file has a default file type of Each line of the op- tions file specifies a format name that can optionally be fol- lowed by _input or _output to restrict the option to either an input or output converter. The second word is a valid option preceded by one or more spaces, tabs, or a slash (/) and can contain uppercase and lowercase letters, numbers, dollar signs, and underlines. The case of letters is not significant. If an option requires a value, then spaces, tabs, or an equal sign can separate the option from the value. You can precede any line by spaces and tabs. To terminate a line, use any character other than those used to specify the format names and options. The syntax and interpretation of the text that follows the format name is specified by the supplier of the front and back end converters for the specified format. To specify several options for the same input or output format, specify one option on a line. If an invalid option for an input or output format or an invalid value for an option is specified, the option may be ignored or an error message may be returned. Each input or output format that supports processing options specifies any restrictions or special formats required when specifying options. By default, any messages that occur during processing of the op- tions file are written to the standard error. For those input and output formats that support a LOG option, messages can be directed to a log file or to a common message log. Specifies the name of the output file that is included in the command syn- tax for compatibility with the cdoc command. Specifies command line options. This option has the same effect as specifying an options file for this converter. You can specify up to 100 op- tions. Specifies a default file extension for compatibility with other operating systems. DESCRIPTION The ddiftext command reads a DDIF formatted file from inputfile and writes a text file to outputfile. To convert from file.ddif to file.text, type: ddiftext file.ddif file.text If you do not supply an input file, or if you supply a minus sign (-) as an argument, ddiftext reads the DDIF file from the standard input file. If you do not supply an output file, or if you supply a minus sign (-) as an argument, ddiftext writes the text file to the standard output file. You can also invoke the ddiftext conversion with the cdoc command when you use that command and specify the option -d text. If the DDIF input file is a newer version of the DDIF grammar than that understood by the converter, data represented by the new grammar ele- ments is lost. Any external file references within the DDIF input file are resolved. All Latin1 text in the intermediate representation of the input file is converted to the text output file. When converting an input file to a text output file, you should be aware that text output files can con- tain only textual content and minimal formatting such as line feeds, page breaks, and tabs. The Text back end converter preserves format- ting information to the extent possible. All graphics, images, and text attributes in the intermediate representation of the input file are lost when converted to the text output file. A document syntax error in the DDIF input file causes a fatal input processing error. The conversion stops and no further input processing occurs. CONVERTER PROCESSING OPTIONS ddiftext supports the following processing options in an options file or in options specified on command lines: Causes text output in 7-bit ASCII. The fallback representation of the characters is described in the ASCII standard. If this option is not specified, the default is OFF; if this option is specified without a value, the default is ON. Causes the converter to put a message in the output file each time a nontext element is encountered. If this option is not specified, the default is OFF; if this option is specified without a value, the de- fault is ON. Specifies the maximum number of lines per page in your text output file. If you specify zero, the number of lines per page will correspond to the height specified in your document. If you addi- tionally specify OVERRIDE_FORMAT, or if the document has no inherent page size, the document is formatted to the height value specified by this option. The default height is 66 lines. Causes the converter to ignore the document formatting information in the document, so that the text is formatted on a single large paragraph per page. Specify the size of the page by the HEIGHT and WIDTH processing options. If this option is not specified, the default is OFF; if this option is speci- fied without a value, the default is ON. Causes the converter to obey the soft directives contained in the document when creating the text output file. If this option is not specified, the default is OFF; if this option is specified without a value, the default is ON. Specifies the maximum number of columns of characters per page in the text output file. If you specify zero, the number of columns per page will corre- spond to the width specified in your document. If you additionally specify OVERRIDE_FORMAT, or if the document has no inherent page size, the document is formatted to the value specified by this processing op- tion. If any lines of text exceed this width value, the additional columns are truncated. The default width is 80 characters.
