This option forces TrEd to search for its library files in the specified directory.

Path to a file with macros for TrEd.

Path to a file with the default set of macros for TrEd.

Maximum number of operations stored by Undo/Redo functions.

This option may be set to 0 to force the Reload function to use the file's attribute pattern setting rather than preserving the current one.

Draw nodes (and value line values) in reverse order.

If 1 is set here, TrEd uses Czech locales. This may be especially useful in macros e.g. for sorting.

The encoding (charset) used for files opened in TrEd. If TrEd runs on Perl 5.8 or higher with Tk804 or higher with Unicode support, arbitrary encoding supported by Perl can be used. In all other cases, only 8-bit encodings are supported and it is necessary to setup the display font for correct displaying.

This option may be used in TrEd running on non-unicode aware Perl and Tk (see above) if the file encoding differs from the encoding used by the display font. In such case, TrEd supports conversions between iso-8859-2 and windows-1250 for Eastern European languages and iso-8859-6 and windows-1256 for Arabic.

This option may be used to provide a path to an SGML parser with support for ESIS output, such as James Clark's SGML parser nsgmls. TrEd may then use this parser to read SGML CSTS files (used e.g. in the Prague Dependency Treebank 1.0).

This option may be used to provide additional parameters to the SGML parser declared in Sgmls option. By default, this option is set to -i preserve.gen.entities. These parameters forces James Clark's nsgmls parser to include a part of CSTS DTD where all global entities are re-declared in such a way that they expand to themselves literally and thus are preserved (as if no expansion was done).

This option may be used to customize the command used by CSTS backend to invoke SGML parser. The default value is %s %o %d %f. In this string, the %s substring is replaced with the value of Sgmls option, %o is replaced with the value of SgmlsOpts option, %d is replaced with the value of CSTSDoctype option, and %f is replaced with the filename. The only requirement is that this command returns a valid representation of the CSTS file in ESIS format on standard output.

This option may be used to customize the command used by CSTS backend to invoke SGML parser for files compressed with GNU GZip. The default value is %z < %f | %s %o %d -. In this string, the %z substring is replaced with the value of zcat option. See CstsParserCommand for more.

This option should point to a file containing CSTS doctype declaration combining both the SGML subset declaration as well as the CSTS DTD. This file is included in the distribution of TrEd and is by default stored in TrEd's library directory as csts.doctype. Setting this option overrides this default.

This option may be used to point TrEd to a GNU gzip command, which may be used for transparent saving files commpressed by GNU gzip. The default value is /bin/gzip -c if /bin/gzip exists and is executable. Otherwise the value is undefined and TrEd does not support transparent saving GNU-zipped files.

This option may be used to point TrEd to a GNU zcat command, which may be used for transparent opening files commpressed by GNU gzip. (These files are recognized by the .gz suffix.) The default value is /bin/zcat if /bin/zcat exists and is executable. Otherwise the value of gzip option is used.
