	call para_destroy to release the current formatter when it is not used
	anymore.

2026-07-25 Patrice Dumas  <pertusus@free.fr>

	* tta/perl/Texinfo/Convert/Info.pm (format_ref): if the
	cross-reference target is an internal identifier, call node_name to
	get the cached value or setup the cached value, it will be present
	or needed for the tag table.

	* tta/perl/Texinfo/Convert/Plaintext.pm (node_name): do not check that
	node_names_text key exists, it should always be initialized.

	* tta/perl/Texinfo/Indices.pm (print_indices_information): check
	if argument is not undef to avoid spurious autovivification.

2026-07-25 Patrice Dumas  <pertusus@free.fr>

	* tta/perl/Texinfo/Convert/Plaintext.pm (_cache_node_names): use the
	same long-living formatter as node_name.

2026-07-25 Patrice Dumas  <pertusus@free.fr>

2026-07-23 Patrice Dumas  <pertusus@free.fr>

	* tta/C/convert/converter.c (set_output_units_files),
	tta/perl/Texinfo/Convert/Converter.pm (set_output_units_files),
	tta/perl/Texinfo/Convert/Info.pm (output):
	rename node_top as top_node.  Rename top_node as top_target_element

	* tta/perl/Texinfo/Convert/Info.pm (output, _info_header): set
	informative commands to the values at the end of the preamble outside
	of _info_header and reset only after converting and caching the node
	names.  Use set_converter_preamble_language_commands and
	reset_lang_translation_from_customization to set all the language
	information.

2026-07-25  Gavin Smith <gavinsmith0123@gmail.com>

	* tta/C/convert/convert_to_plaintext.c (convert_to_plaintext_internal):
	Add TODO comment to match structure of Perl code.

2026-07-24  Gavin Smith <gavinsmith0123@gmail.com>

	* tta/C/convert/convert_to_plaintext.c:
	Initial implementation of handling "quoted commands".

2026-07-24  Gavin Smith <gavinsmith0123@gmail.com>

	Split quoted commands from "style map"

	* tta/perl/Texinfo/Convert/Plaintext.pm,
	(@quoted_commands, %quoted_commands): Change from array to hash.
	(%style_map): Do not add quoted commands.
	(conversion_initialization) <quoted commands>: Rather than updating
	$self->{'style_map'}, save the open and close quote strings in
	$self->{'open_quote'} and $self->{'close_quote'}.
	(_convert) <style map commands>: Check for commands in %quoted_commands
	as well as in $self->{'style_map'};
	
	This is intended to simplify the C implementation as it will be
	slightly easier to check a Boolean flag for a Texinfo command
	rather than retrieving string values for that command.  Many of the
	"quoted commands" are very frequently used commands such as @code
	so this should simplify a common case.
	This also means that the only command left whose values are likely
	to change inside $self->{'style_map'} is @dfn.

2026-07-24  Gavin Smith <gavinsmith0123@gmail.com>

	* tta/perl/Texinfo/Convert/Plaintext.pm
	(%no_punctation_munging_commands, no_punctuation_munging_commands):
	Rename.  Remove 'var' as it is no longer checked for in this hash.

2026-07-24  Gavin Smith <gavinsmith0123@gmail.com>

	Split out handling of @var and @sc from "style map"

	* tta/perl/Texinfo/Convert/Plaintext.pm (_convert) <style map>:
	Separate handling of "upper case commands" (@var and @sc) from
	handling of commands added to $self->{'style_map'}.  Most of the
	code in the "style map" clause was irrelevant, except for the
	code under the %no_punctation_munging_commands (sic) condition to
	set frenchspacing, which applied to @var.  However, @var already
	had special-case code under the "upper case commands" condition,
	so adding the frenchspacing code under the @var condition doesn't
	increase complexity too much.
	(@asis_commands): Remove 'var', 'sc'.

2026-07-23  Gavin Smith <gavinsmith0123@gmail.com>

	Shadow targets for texinfo.tex
	
	* doc/texinfo.tex (\donoderef): If no preceding @node, use the
	section text itself as the target name, passed to new macro

	(\setrefshadow): Output @xrshad line to .aux file for shadow target,
	and run \pdfdest in PDF output.
	(\setref, \dosetref): Split out \dosetref.
	
	(\xrshad): Provide definition for control sequence written to .aux
	file.  Save information on shadow targets.
	
	(\checkshadowactive): New macro, used to check if a shadow target can
	be referenced.
	(\xrefX): Use \checkshadowactive to decide if we should output a
	reference to a shadow target or not.

	(\xrdef, \xrdefctxt): Split out \xrdefctxt.
	(\getrefx): Use \xrdefctx.  Check for a shadow target if information
	on the target couldn't be found.

	(\countA): Move definition earlier in file to use it as a
	general purpose count register.

2026-07-23 Patrice Dumas  <pertusus@free.fr>

	* tta/C/main/plaintext_converter_state.h (PLAINTEXT_COMMAND_STRUCT):

	setup default ignored commands in plaintext_commands_data flags.  Add
	commands_data PLAINTEXT_COMMAND_STRUCT array in
	PLAINTEXT_CONVERTER_STATE.  Copy plaintext_commands_data to
	commands_data in plaintext_converter_initialize, and modify based on
	customization.

	* tta/C/convert/convert_to_plaintext.c (PF_informative)
	(plaintext_format_setup, convert_to_plaintext_internal): setup
	informative commands as a flag in plaintext_commands_data.

2026-07-22 Patrice Dumas  <pertusus@free.fr>

	* tta/C/convert/convert_to_plaintext.c (plaintext_free_converter):
	free plaintext_converter only if it was allocated.  It is allocated

	(SORTED_INDEX_NAMES, ACCENT_ENTITY_INFO, COMMAND_ACCENT_ENTITY_INFO),
	tta/C/main/html_converter_state.h, tta/maintain/generate_css_data.pl:
	now that HTML_CONVERTER_STATE is used through a pointer, it is
	possible to have a declaration without definition and reverse the
	inclusion order of header files, by having html_converter_state.h
	include converter_types.h.  Move back some non-HTML specific types to
	converter_types.h.  Add #include "html_converter_state.h" where
	needed.

	* tta/C/convert/convert_to_plaintext.c, tta/C/main/converter_types.h
	(CONVERTER): declare struct PLAINTEXT_CONVERTER_STATE and do not

2026-07-22  Gavin Smith <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (HTML Output Structure Customization):
	Move discussion of SPLIT after discussion of USE_NODES and say
	that by default, "each output unit" rather than "each node" is
	output in a separate file as this may not be the case if USE_NODES=0.

2026-07-22  Gavin Smith <gavinsmith0123@gmail.com>

	* info/signals.c (info_signal_proc) <SIGWINCH>:
	Do not attempt to unblock signal, as this should be unnecessary.

2026-07-22  Gavin Smith <gavinsmith0123@gmail.com>

	* info/signals.c, info/signals.h:

2026-07-22 Patrice Dumas  <pertusus@free.fr>

	* info/info.c (main): fix removed first letters of function name
	calls.

2026-07-22 Patrice Dumas  <pertusus@free.fr>

	C plaintext converter output and convert

	* tta/C/convert/convert_to_plaintext.c
	(plaintext_converter_initialize): fix sizeof call.

	* tta/C/convert/convert_to_plaintext.c (plaintext_convert_tree): do

	info/signals.c, info/tag.c, info/tilde.c, info/variables.c,
	info/session.h:
	Expand tabs used for indentation in files where they are anomalous.
	
	Leading tabs can make the output of "git diff" look wrong due

	info: do less in SIGWINCH handler
	
	* info/signals.c (signal_block_winch, signal_unblock_winch):
	Remove functions.  Remove all calls to these functions.
	(sigwinch_block_count): Remove.
	(This reverses much of change on 2014-07-07.)

	(info_signal_proc) <SIGWINCH, SIGUSR1>: Do not do any redrawing

	to indicate that the terminal size may have changed and that windows
	need to be redrawn.
	(maybe_update_after_signal): New function, to be called outside of
	a signal handler on a regular basis.  Redraw display if it's possible
	the screen size has changed.
	
	* info/session.c (fill_input_buffer): Call maybe_update_after_signal.
	
	According to C standards and glibc documentation, accessing data
	structures or calling library functions in a signal handler can
	lead to undefined behaviour.

2026-07-21 Patrice Dumas  <pertusus@free.fr>

	Continue C plaintext converter and conversion initialization

	* tta/C/convert/converter.c (initialize_cmd_list),
	tta/C/convert/html_prepare_converter.c: move initialize_cmd_list to
	converter.c.

	* tta/C/convert/convert_to_plaintext.c
	(plaintext_converter_initialize),
	tta/C/main/plaintext_converter_state.h (PLAINTEXT_CONVERTER_STATE):
	implement plaintext_converter_initialize.

	* tta/perl/Texinfo/Convert/Plaintext.pm (converter_initialize):
	info_special_chars_warning is an integer, not a string.

	* tta/C/convert/convert_to_plaintext.c
	(plaintext_conversion_initialization, informative_global_commands)
	(contents_commands, plaintext_free_converter)
	(plaintext_converter_initialize),
	tta/C/main/plaintext_converter_state.h (PLAINTEXT_CONVERTER_STATE):
	being the implemention of plaintext_conversion_initialization.

	* tta/C/convert/convert_to_plaintext.c (format_raw_cmd)
	(PLAINTEXT_COMMAND_STRUCT, plaintext_commands_data)
	(plaintext_format_setup), tta/C/convert/converter.c
	(converter_format_data): setup constant data related to raw formt
	commands.

2026-07-20  Gavin Smith <gavinsmith0123@gmail.com>

	Change info test not to use :cntrl: in grep regex

	* info/t/quoted-index-target.sh: Strip out DEL bytes
	from output file with tr.  Remove use of "[[:cntrl:]]" in
	grep regex to check for such bytes.  Alter test slightly
	to be effective with updated regex, using "--index-search"
	instead of "--index-search --all", which means we actually
	go to the referenced node.

	The use of "[[:cntrl:]]" in a grep regex led to a failure on
	Solaris 11, where apparently such character classes are not
	recognised by the grep program.  Report from Bruno.

2026-07-20  Gavin Smith <gavinsmith0123@gmail.com>

	* info/info.c (main) <--index-search>:
	Pass -1 as starting offset to next_index_match otherwise we
	skip over the very first index entry in the first index node.

2026-07-19  Gavin Smith <gavinsmith0123@gmail.com>

	* doc/texinfo.tex (\include): Remove \tracingmacros=1 left in
	by mistake.

2026-07-18  Gavin Smith <gavinsmith0123@gmail.com>

	Remove unused definitions for !HAVE_SIGPROCMASK

	(sigmask, SIG_UNBLOCK, SIG_BLOCK, sigset_t, sigemptyset, sigfillset)
	(sigaddset, sigdelset, sigismember, sigsuspend):
	Remove #define's as these symbols are not otherwise used under
	this condition.

2026-07-18  Gavin Smith <gavinsmith0123@gmail.com>

	Remove check of SA_NOCLDSTOP
	
	* info/signals.c (initialize_info_signal_handler):
	Use #ifdef HAVE_SIGACTION instead of #ifdef SA_NOCLDSTOP.
	* info/signals.h: Remove check of SA_NOCLDSTOP from condition.
	
	The use of SA_NOCLDSTOP was introduced on 2004-03-27 for
	the benefit of Solaris 7, which is likely no longer a relevant
	system to support.
	signals.h had a comment referencing "sort.c" in the coreutils
	sources, but recent coreutils sources do not check SA_NOCLDSTOP
	any more (likely since change on 2025-11-22).

2026-07-18  Gavin Smith <gavinsmith0123@gmail.com>

	* info/signals.h:
	Remove use of HAVE_SIGSETMASK conditional.  Check for
	sigsetmask was removed on 2019-02-17.

2026-07-19 Patrice Dumas  <pertusus@free.fr>

	* tta/TODO: link to recently started discussions on manuals
	translations.

	Improve comments.

2026-07-18  Gavin Smith <gavinsmith0123@gmail.com>

	* configure.ac (AC_CHECK_FUNCS):
	Re-add sigprocmask as HAVE_SIGPROCMASK is used in
	info/signals.h.

2026-07-18  Gavin Smith <gavinsmith0123@gmail.com>

	* configure.ac (AC_CHECK_FUNCS):
	Remove check for sigprocmask.

	* info/signals.c (info_signal_proc)
	[!HAVE_SIGACTION && HAVE_SIGPROCMASK]:
	Remove code.  Systems without sigaction but which do have
	sigprocmask may be rare - the Gnulib manual only mentions
	that both functions are missing on mingw and MSVC 14.
	(term_conf_busy): Remove unused.

2026-07-18  Gavin Smith <gavinsmith0123@gmail.com>

	* info/scan.c (scan_reference_target) <menu entry>:
	Allow tab to follow period in terminating node name.

2026-07-18  Gavin Smith <gavinsmith0123@gmail.com>

	Use sig_atomic_t

	* info/signals.c [!HAVE_SIGACTION] (term_conf_busy),
	(sigwinch_block_count):
	Declare as volatile sig_atomic_t rather than int, as they
	are accessed inside the signal handler info_signal_proc.

2026-07-17  Gavin Smith <gavinsmith0123@gmail.com>

	* info/signals.c (info_signal_handler) [!HAVE_SIGACTION]:
	Remove #define of info_signal_handler to info_signal_proc.
	This is incorrect as the former is a structure and the latter
	is a function.  info_signal_handler is not referred to
	elsewhere in this file under !HAVE_SIGACTION, except under
	#ifdef SA_NOCLDSTOP, where it is accessed as a structure.  If
	both conditions are true, there is a compilation error.
	
	This #define appears to have been present since the use of sigaction
	was introduced in a patch by AIDA Shinra, dated 2003-01-25.

2026-07-17  Gavin Smith <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (Images, Image Syntax):
	Try to discourage using images inside paragraphs.

2026-07-17  Gavin Smith <gavinsmith0123@gmail.com>

	* tta/perl/XSTexinfo/ParagraphXS.xs (para_add_to_counter):
	New functions.

	* tta/perl/Texinfo/Convert/Plaintext.pm (_convert) <image>:
	Call it in order to account for some horizontal space taken
	up by an image.  Add a comment describing the unsatisfactory
	situation.
	
	Report from Werner.

2026-07-16  Gavin Smith <gavinsmith0123@gmail.com>

	Change paragraphindent from string to integer

	* tta/data/options_data.txt: declare paragraphindent as integer

	* tta/perl/Texinfo/Common.pm (informative_command_value),
	* tta/C/main/utils.c (informative_command_value),
	* tta/perl/texi2any.pl,
	* tta/C/texi2any.c:
	For paragraphindent, save 'asis' value as -2 and 'none' value as 0.

	* tta/perl/Texinfo/Convert/Plaintext.pm (_convert): update to handle
	paragraphindent setting as integer.

	* tta/C/convert/convert_to_plaintext.c: update

	This simplifies the C conversion code as we now don't need to call
	strcmp and strtol for every paragraph.

2026-07-16  Gavin Smith <gavinsmith0123@gmail.com>

	LaTeX: \smallbreak before definition

	* tta/perl/Texinfo/Convert/LaTeX.pm (_convert_def_line):
	Output \smallbreak before definition output.
	
	Report from Dimitris Papavasiliou <dpapavas@protonmail.ch>.

2026-07-15  Gavin Smith <gavinsmith0123@gmail.com>

	* tta/C/main/text.c (text_abandon, text_yield): Rename
	and return pointer to text buffer.

2026-07-15  Gavin Smith <gavinsmith0123@gmail.com>

	Continue C plaintext converter

	* tta/C/main/text.c (text_abandon): New function.

	* tta/C/convert/convert_to_plaintext.c
	(stream_reset, stream_yield_result): New.
	(convert_to_plaintext): Call stream_yield_result to avoid calling
	strdup unnecessarily.

2026-07-15  Gavin Smith <gavinsmith0123@gmail.com>

	* tta/perl/Texinfo/Convert/Plaintext.pm
	(_stream_reset, _stream_yield_result): New functions.

	* tta/C/convert/convert_to_plaintext.c (convert_to_plaintext_internal):
	Return statement after processing text now matches Perl code.

2026-07-14  Gavin Smith <gavinsmith0123@gmail.com>

	* tta/perl/Texinfo/Convert/Plaintext.pm (_convert):
	Return after processing text.

2026-07-14  Gavin Smith <gavinsmith0123@gmail.com>

	Rename generated file.

	* tta/C/main/element_types.awk: Rename generated file
	element_types.c to types_data.c.  This means that the comment
	at the top of tta/C/main/types_data.h refers to a file which
	exists, types_data.c, for which it contains declarations.
	
	This code has changed before, most recently in 2024-05-31
	when the number of .c files generated by this helper program
	was reduced from 2 to 1.

2026-07-14  Gavin Smith <gavinsmith0123@gmail.com>

	* tta/:
	run "gnulib --add-import unistr/u32-mbsnlen unistr/u32-mbtouc".
	Report from Bruno Haible.

2026-07-14  Gavin Smith <gavinsmith0123@gmail.com>

	* tta/: run "gnulib --remove-import unistr/u32-strdup" as
	this module is not needed any more.

2026-07-14  Gavin Smith <gavinsmith0123@gmail.com>

	* info/t/quoted-index-target.sh: update test

2026-07-14  Thomas <thomb@pm.me>  (tiny change)

	* info/indices.c (format_reference):
	Place quoting DEL bytes around node name if it contains a :.
	* info/scan.h, info/scan.c: move INFO_QUOTE, INFO_QUOTE_STR definition
	to scan.h.

2026-07-14  Gavin Smith <gavinsmith0123@gmail.com>

	* info/t/quoted-index-target.sh: in grep regular expression, replace
	"[[:blank:]]\{1,\}" with "  *", as this seems simpler and avoids any
	hint of locale dependence.

2026-07-12  Gavin Smith <gavinsmith0123@gmail.com>

	* tta/C/main/unicode-collation: sync

2026-07-12  Gavin Smith <gavinsmith0123@gmail.com>

2026-07-12  Gavin Smith <gavinsmith0123@gmail.com>

	* tta/data/converters_defaults.txt:
	Add section for 'plaintext'.  Edit comments at top of file.

	* tta/perl/Texinfo/Convert/Plaintext.pm (%defaults):
	Set with Texinfo::Options::get_regular_options.

2026-07-11  Gavin Smith <gavinsmith0123@gmail.com>

	Fix messaging after index search

	* info/indices.c (info_indices_of_file_buffer):
	Reset list of index entries once we find a node with
	an index tag.
	* info/t/infodir/index-search.info: Add missing index tag to
	test file.
	
	It was possible that the string "CAN'T SEE THIS" would
	be displayed as the name of an index in the message line,
	due to incorrect internal counting of index entries.

2026-07-11  Thomas <thomb@pm.me>  (tiny change)

	* info/t/quoted-index-target.sh: new test.

2026-07-11  Gavin Smith <gavinsmith0123@gmail.com>

	Fix index reference to node with : in its name

	* info/scan.c (scan_reference_label): Include DEL byte in
	argument to strcspn.  This reverses change on 2024-12-30.

2026-07-10  Gavin Smith <gavinsmith0123@gmail.com>

	* README-hacking: remove missed self-destructing note for post

	* tta/maintain/regenerate_perl_options_info.pl,
	* tta/maintain/regenerate_C_options_info.pl:
	Reference converter_defaults.txt and relevant Makefile.am files.
	Correct file names in comments at tops of files.

	* tta/perl/Makefile.am: Add comment about keeping a file name in
	sync with a comment in a another file.

	The thinking behind these comments is that if someone finds one
	of these files is relevant to converter options values, they should
	be easily able to find how they are set and used across the rest of
	the code base.
	They should also be able to easily know what comments to update
	in case of any changes to prevent out-of-date information.

2026-07-10  Gavin Smith <gavinsmith0123@gmail.com>

	Continue C plaintext converter

	* tta/C/convert/convert_to_plaintext.c (convert_to_plaintext_internal):
	Get paragraphindent conf value as string with strtoul.  From Patrice.

2026-07-10  Gavin Smith <gavinsmith0123@gmail.com>

	Continue C plaintext converter

	* tta/C/convert/convert_to_plaintext.c (convert_to_plaintext_internal):
	Don't get paragraph indent from self->conf until we work out how to do

	improvement in the output at this stage of development.)

2026-07-09  Gavin Smith <gavinsmith0123@gmail.com>

	Simplify new_formatter interface

	* tta/perl/Texinfo/Convert/Plaintext.pm (new_formatter):
	Take 'indent_length' and 'indent_length_next' as subroutine
	parameters rather than hash values.  This should make this function
	easier to replicate in a C reimplementation.
	(convert_line, convert_line_new_context): Likewise.

2026-07-08  Gavin Smith <gavinsmith0123@gmail.com>

	Simplify new_formatter interface

	* tta/perl/Texinfo/Convert/Plaintext.pm (_convert) <list of floats>:
	Do not pass "max" configuration value to 'new_formatter' as 'new_formatter'
	retrieves this value itself.  This allows simplifying the interface of
	'new_formatter' as now the only configuration values it takes are
	'indent_length' and 'indent_length_next'.

2026-07-07  Gavin Smith <gavinsmith0123@gmail.com>

	* tta/C/convert/convert_to_plaintext.c:

	* tta/perl/Texinfo/Convert/Plaintext.pm (_open_code, _convert),
	* tta/perl/Texinfo/Convert/Info.pm (_format_ref):
	Use these instead of set_space_protection, as it's easier to
	understand without remembering what all the arguments to
	set_space_protection mean.

2026-07-06 Patrice Dumas  <pertusus@free.fr>

	* tta/C/main/manipulate_indices.c (print_indices_sort_strings): inline
	setup_indices_entries_sort_strings in print_indices_sort_strings and
	remove.  More comments.

	* tta/C/main/manipulate_indices.c (INDEX_ENTRIES_SORT_STRINGS)
	(find_indices_entries_sort_strings_index, print_indices_sort_strings):
	replace index field in INDEX_ENTRIES_SORT_STRINGS by index_name, as it
	is all that is accessed from the index.

	* tta/perl/t/z_misc/test_sort.t: more comments.

2026-07-06 Patrice Dumas  <pertusus@free.fr>

	* tta/C/main/document.c (document_sorted_indices_by_index)

	(print_indices_information): split out of
	print_document_indices_sort_strings the association of index entries
	to sort strings and the output of sort strings by index to the
	print_indices_sort_strings function, moved to manipulate_indices.c or
	Indices.pm. Move INDEX_ENTRIES_SORT_STRINGS,
	INDICES_ENTRIES_SORT_STRINGS, find_indices_entries_sort_strings_index

	* tta/C/convert/texinfo.h, tta/swig/texinfo.i: remove
	STTF_setup_index_entries_sort_strings now that it has no effect.
	Update users.

2026-06-16 Patrice Dumas  <pertusus@free.fr>

	Add separate functions to sort index entries and cache in converters

	* tta/C/Makefile.am (C_libtexinfo_convert_sources): add
	tta/C/convert/convert_indices.c.

	* tta/C/convert/convert_indices.c (new_index_entry_text_or_command)
	(idx_leading_text_or_command)
	(index_entry_first_letter_text_or_command): move to convert_indices.c,
	since index_entry_first_letter_text_or_command should only be called
	from converters.

	* tta/C/main/document.c (document_sorted_indices_by_index)
	(document_sorted_indices_by_letter): rename sorted_indices_by_index as
	document_sorted_indices_by_index and sorted_indices_by_letter as
	document_sorted_indices_by_letter.

	* tta/C/main/manipulate_indices.c (document_index_content_element),
	tta/perl/Texinfo/Indices.pm (document_index_content_element):
	rename index_content_element as document_index_content_element.

	(get_index_content_info_element, document_index_content_element):
	add get_index_content_info_element that gets index content element for
	the cases where translation is not needed, and also gets information
	on object-oriented definitions that can be used by the caller to
	prepare an index content element.  Remove def_command_index_entry.

	* tta/C/main/manipulate_indices.c (entry_tree_element_sort_string)
	(index_entry_element_sort_string): add entry_tree_element_sort_string
	based on index_entry_element_sort_string code.

	* tta/C/main/manipulate_indices.c (setup_index_entries_sort_strings):
	add index_entry_element_sort_string_fn argument to be able
	to use a different function than the index_entry_element_sort_string
	default, when called from converters.  A function argument instead of
	a call to a function if converter argument is set is used to avoid
	depending on the libtexinfo-converter library.

	* tta/C/main/document.c (document_sorted_indices_by_index)
	(document_sorted_indices_by_letter),
	tta/C/main/manipulate_indices.c (new_collation_sorted_indices_by_index)

	new_collation_sorted_indices_by_letter and
	find_collation_sorted_indices_by_letter to manipulate_indices.c.

	(sort_indices_by_index, sort_indices_by_letter):
	use indices_sort_strings as argument to sort_indices_by_index,
	sort_indices_by_letter and setup_sort_sortable_strings_collator, do
	not call document_indices_sort_strings in those functions, but in

	before calling sort_indices_by_index or sort_indices_by_letter.

	tta/perl/Texinfo/Indices.pm (converter_index_content_element),
	tta/perl/Texinfo/IndicesNonXS.pm (index_entry_element_sort_string): add
	index sorting functions for converters that cache in the converter,
	using the new fields indices_sort_strings, sorted_indices_by_index and
	sorted_indices_by_letter, and use converter information.  Use those
	functions in get_converter_indices_sorted_by_*, in
	index_entry_first_letter_text_or_command and in converters.
	Remove document_index_content_element converter and consider only the
	case of no converter in this function. Update
	callers, replacing index_content_element by
	converter_index_content_element in converters.  Remove
	index_content_element.

	Fix M-TAB moving before DEL-quoted cross-reference

	* info/scan.c (scan_reference_label) [hide-note-references=On]:
	If "quoting" DEL bytes surround the reference label, remove them
	when rewriting the node contents.
	
	Because these bytes are invisible, if the node position is placed
	on one of these bytes, it would be advanced past that byte in
	display_cursor_at_point, which is called in the main loop in
	info_read_and_dispatch.  Then the cursor would get "stuck"
	when trying to move before a cross-reference with M-TAB.

	* info/session-cmd.c (info_handle_pointer):
	If going up to a different file, do not try to find the current
	node in the new node's menu.  This led to a bad result when going
	"Up" to the dir node.

	Report from Aidan <aidanczhai@gmail.com>.

2026-04-09  Gavin Smith <gavinsmith0123@gmail.com>

	No crash for repeated visit to "*" node

	If nodename is "*", set replica bit on node so to avoid attempt
	to free the contents of the node.

	Report from Aidan <aidanczhai@gmail.com>.

2026-04-09  Gavin Smith <gavinsmith0123@gmail.com>

	Fix searching dir node

	* info/scan.c (scan_node_contents): Clear N_Simple flag.
	As we used info_node_of_tag_fast to build the dir node, the final
	dir node still had this flag set on it, which led to an infinite
	recursion in info_search_in_node_internal attempting to retrieve
	the dir node without the N_Simple flag set.

	* info/session-cmd.c (info_search_internal): Avoid attempting
	to load other nodes when searching in the dir node (or other nodes
	flagged as internal).

	their contents.  Only call scan_node_contents once, on the composite
	dir node.
	
	When hide-note-references was On, the dir node was completely broken
	due to parts of it being processed by scan_node_contents multiple
	times.  Report from Aidan <aidanczhai@gmail.com>.

2026-04-08 Patrice Dumas  <pertusus@free.fr>

	* tta/C/main/translations.c (translate_string),
	tta/perl/Texinfo/Translations.pm (translate_string): only get the main

	region codes do not prevent matching the main language, in case
	gettext does not do it already.

	* tta/perl/t/test_utils.pl (test): pass COMMAND_LINE_ENCODING to
	convert_to_text.

	* tta/perl/Makefile.tres, tta/perl/t/languages.t

	(forward_move_node_structure, backward_move_node_structure)

	not be true if called via move-to-next-xref (or move-to-prev-xref).

	(point_next_line, point_prev_line, _scroll_backward, _scroll_forward):
	Reinstate the removed messages for cursor movement and scrolling
	commands where they would be accurate.

2026-04-02  Gavin Smith <gavinsmith0123@gmail.com>

	* info/variables.c (ALIAS_VAR, alias_var):
	New macro and dummy variable for declaring an alias of a variable.
	(info_variables) <"scroll-behavior">: Use it.
	(variable_by_name): Check if variable is an alias and if so resolve
	the alias.
	
	This is to avoid using separate 'where_set' fields for the two
	equivalent names of the variable, which could lead to inconsistency,
	including in the help buffer.

2026-04-02  Gavin Smith <gavinsmith0123@gmail.com>

	* info/variables.c (set_variable_to_value):
	For variables with a list of possible choices, if requested value
	is not in that list, do not update 'where_set' field and return 0.
	
	This has the effect of printing an error message if an incorrect
	value is used in an infokey file, which wasn't done before with this
