379 The &gnum; file format is handled using two different code
380 bases. The older version is part of the application
381 itself. The newer version is in a plugin called

383 on SAX.

395 The &gnum; file format stores the file contents in the

398 compression library.
399 </para>
401 <para>
402 The &gnum; file format is designed to be flexible and
403 powerful. The format is easily processed by computers. The
404 format can readily be improved as gnumeric develops
405 without breaking compatibility with older versions. The
406 format is designed to be easily translated into text so
407 that it can be read by humans.

502 Direct manipulation of &gnum; files is possible by
503 transforming the files to text files and then using
504 standard text file tools like document editors. In order
505 to read the contents a &gnum; file must first be
506 decompressed and can then be opened. In GNU systems, the
507 &gnum; default file "Book1.gnumeric" can be uncompressed
508 as follows:
509 <screen>
510 zcat Book1.gnumeric > Book1.text
511 </screen>
512 alternatively, the file can be renamed and then
513 uncompressed with the following pair of commands:
514 <screen>
515 cp Book1.gnumeric Book1.text.gz
516 gunzip Book1.text.gz
517 </screen>
518 both possibilities yield the file "Book1.text" which is
519 an ASCII text file. This file can be opened in any editor,
520 like <application>Vim</application> or
521 <application>Emacs</application>,
522 or pager, like <application>Less</application>.

676 <para>
677 The Comma Separated Value (CSV) and Tab Separated Value (TSV) file
678 formats are a common
679 structuring strategy for text format files. In these files, each
680 line in the file represents a row of data and, within each line
681 of the file, the different data fields are separated from one
682 another using a separator character, often a comma, semicolon or tab.
683 &gnum; handles CSV and TSV files through the text
684 importer and exporter but these formats are given their own
685 definitions in this document because they are considered very common
686 formats.
687 </para>
689 <para>
690 &gnum; will automatically open CSV and TSV format files separating each
691 row into columns based on the presence of appropriate separator
692 characters in
693 the file. If the automatic import leads to any errors, these can
694 generally be corrected by using the "Text Import (configurable)"
695 file format instead. Selecting that file format will launch the
696 <interface>Text Import</interface> druid which allows the user
697 to import CSV and TSV format files while specifying in greater detail
698 the settings of the import configuration parameters. See the
699 section on <link linkend="sect-file-textImport">importing text
700 files</link> or the section on <link
701 linkend="sect-file-textExport">exporting text files</link> for
702 an explanation of how to open or save CSV and TSV files through the
703 <interface>Text Import</interface> druid.

1330 second, defining a LaTeX variable which is used as a dummy
1331 tag to exclude the preamble used to process the file on
1332 its own. The LaTeX file generated by &gnum; requires using
1333 the following lines in the preamble
1334 <screen>
1335 \usepackage{ucs}
1336 \usepackage{utf8}{inputenc}
1337 \usepackage{color}

1343 \usepackage{ifthen}

1345 to include each of these packages. Optionally, to include
1346 the table in landscape mode, the preamble also needs the line
1347 <screen>
1348 \usepackage{lscape}
1349 </screen>
1350 to include the <literal>lscape</literal> package. Second,
1351 the following line
1352 <screen>
1353 \def\inputGnumericTable{}
1354 </screen>
1355 must be included to make the LaTeX processor ignore the
1356 preamble section of the file generated by &gnum;. The
1357 generated file can be included either by adding, at the
1358 appropriate location in the other file, the line
1359 <screen>
1360 \input{<replaceable>mygnumericfile.tex</replaceable>}
1361 </screen>

1372 An option is provided in the file allows the table to be
1373 presented in landscape mode which allows wider tables to
1374 be included. For files which are to be processed
1375 independently, the option can be changed in the document

1382 by removing the percent symbol (%) in front of
1383 <literal>,landscape</literal>. For files to be included as
1384 tables in other LaTeX files, the preamble must include the
1385 <literal>lscape</literal> package, as was explained above,
1386 and the two commands
1387 <screen>
1388 \def\gnumericTableEnd{\end{landscape}}
1389 \begin{landscape}
1390 </screen>
1391 must have the leading percent sign removed.

1398 An option is provided to change the widths of the columns
1399 of the file generated by &gnum;. By default, the file
1400 attempts to maintain the proportions between the columns
1401 in the &gnum; worksheet, yet scale the resulting table for
1402 the width of the paper defined in LaTeX. To change the
1403 column widths, look for the section in the
1404 <application>LaTeX</application> file with lines that look
1405 like
1406 <screen>
1407 \def\gnumericColA{107pt*\gnumericScale}
1408 \def\gnumericColB{89pt*\gnumericScale}
1409 \def\gnumericColC{98pt*\gnumericScale}
1410 \def\gnumericColD{89pt*\gnumericScale}
1411 \def\gnumericColE{89pt*\gnumericScale}
1412 </screen>
1413 and that may have as many entries as there were columns in
1414 the worksheet. The TeX 'lengths' defined for each column
1415 can be changed. For example, change the second column
1416 (Column B) to a width of 0.75 inches, we would simply have
1417 to modify this code to:
1418 <screen>
1419 \def\gnumericColA{107pt*\gnumericScale}
1420 \def\gnumericColB{0.75in}
1421 \def\gnumericColC{98pt*\gnumericScale}
1422 \def\gnumericColD{89pt*\gnumericScale}
1423 \def\gnumericColE{89pt*\gnumericScale}
1424 </screen>
1425 and the resulting file would have a second column 0.75
1426 inches wide.
1427 </para>
1429 <para></para>
1430 <!-- TODO Ask Shaun: why is this needed to get a par break? -->
1432 <para>
1433 An option to change the headers and footers of the table
1434 is provided as well. The file itself contains comments on
1435 how to alter these but the choices will require seeing the
1436 documentation of the <literal>longtable</literal> LaTeX
1437 package. See that documentation and the contents of the
1438 file generated by &gnum; for details.

3022 Files in the text file format are files in which the bytes
3023 represent the text characters of a particular character set
3024 using a specific system to relate the binary numbers in the file
3025 to the text characters of the set. Such systems are called
3026 'encodings' and become an issue when the file includes
3027 characters that are not in the standard ASCII set, such as
3028 characters in languages other than English. Character encodings
3029 are explained in greater detail in <xref
3030 linkend="sect-file-textImport-complex-encoding"/>.

3046 will be read into a workbook or existing workbooks will be

3048 </para>
3050 <para>
3051 The Text file format includes a number of different formatting
3052 strategies for text files in which data fields are structured in
3053 a regular pattern. Most of these formats represent rows of data
3054 on different lines of the file using different strategies to
3055 separated data values within each row. 'Fixed-width' formats
3056 place each data entry in a separate column and therefore limit
3057 the size of the data entries. 'Separated' formats use a special
3058 character or character sequence to separate entries. For
3059 instance, the comma separated value, the tab separated value
3060 formats and the space separated value formats use commas, tabs,
3061 and spaces respectively to separate the data fields.

3065 &gnum; can import and export files from and to a wide variety

3067 formats when the text importer or the text exporter is

3069 different encodings. See the section on <link
