12.2 Texinfo::Convert::Text SYNOPSIS

  use Texinfo::Convert::Text qw(convert_to_text ascii_accent text_accents);

  my $result = convert_to_text($tree);
  my $result_encoded = convert_to_text($tree,
             {'enabled_encoding' => 'utf-8'});
  my $result_converter = convert_to_text($tree,
             {'converter' => $converter});

  my $result_accent_text = ascii_accent('e', $accent_command);
  my $accents_text = text_accents($accents, 'utf-8');

12.3 Texinfo::Convert::Text NOTES

The Texinfo Perl module main purpose is to be used in texi2any to convert Texinfo to other formats. There is no promise of API stability.

12.4 Texinfo::Convert::Text DESCRIPTION

Texinfo::Convert::Text is a simple backend that converts a Texinfo tree to simple text. It is used in converters, especially for file names. The converter is very simple, and, in the default case, cannot handle output strings translation or error handling.

12.5 Texinfo::Convert::Text METHODS

$result = convert_to_text($tree, $options)

Convert a Texinfo tree to simple text. $options is a hash reference of options. The converter is very simple, and has almost no internal state besides the options. It cannot handle as is output strings translation or error storing.

If the converter option is set, some additional features may be available for the conversion of some @-commands, like output strings translation or error reporting.

The following options may be set:


If set, the value is considered to be the encoding name texinfo accented letters should be converted to. This option being set corresponds to the --enable-encoding option, or the ENABLE_ENCODING customization variable for Info and Plaintext and for some conversion to text in other formats. For file names in HTML and LaTeX, and for DocBook or Texinfo XML, this variable should in general be set unless the output encoding is US-ASCII.


If set, the text is upper-cased.


If set the text is in code style. (mostly --, ---, '' and `` are kept as is).


If set, sections are numbered when output.


A somehow internal option to convert to text more suitable for alphabetical sorting rather than presentation.


If this converter object is passed to the function, some features of this object may be used during conversion. Mostly error reporting and strings translation, as the converter object is also supposed to be a Texinfo::Report objet. See also Texinfo::Convert::Converter.


A reference on a hash. The keys should be format names (like html, tex), and if the corresponding value is set, the format is expanded.

$result_accent_text = ascii_accent($text, $accent_command)

$text is the text appearing within an accent command. $accent_command should be a Texinfo tree element corresponding to an accent command taking an argument. The function returns a transliteration of the accented character.

$result_accent_text = ascii_accent_fallback($converter, $text, $accent_command)

Same as ascii_accent but with an additional first argument converter, which is ignored, but needed if this function is to be in argument of functions that need a fallback for accents conversion.

$accents_text = text_accents($accents, $encoding, $set_case)

$accents is an accent command that may contain other nested accent commands. The function will format the whole stack of nested accent commands and the innermost text. If $encoding is set, the formatted text is converted to this encoding as much as possible instead of being converted as simple ASCII. If $set_case is positive, the result is meant to be upper-cased, if it is negative, the result is to be lower-cased.
