Patch #328 - 2017/06/01

• revise parser for charClass resource, making these improvements:
  • accept octal and hexadecimal values
  • allow embedded whitespace
  • allow the class after colon to be optional, e.g., to clear class settings for a range of characters.
• add command-line option -report-charclass.
• fix most lintian warnings about test-package
• add eraseSavedLines resource.
• document DECSED 3 in ctlseqs.ms (report by Ben Longmans).
• improve integration between configure-events and updates for reported screensize, in particular when switching between vt100 and tek4014 modes.
• modify selection-highlighting of reverse-video text to keep that distinct, e.g., by reversing the selection foreground and background colors as one would expect. This fixes a "useless" case in the description of highlightColorMode.
• improve fix for Debian #759734, addressing a case where non-colored cursor would be invisible against reverse-video (see patch #311).
• updates for ReGIS (Ross Combs):
  • the "H" option of the "T" command should multiply by 10, not 20.
  • display unknown glyphs as a solid block.
  • given a succession of text-direction options, use the last.
  • fix the direction of ReGIS slanted text so that negative values produce oblique output .
  • fix the ReGIS text direction option to only rotate characters when no following size option is used.
• update terminfo to better match corresponding entries in ncurses, e.g., u8 pattern to match the VT220, VT420, etc., primary responses, as well as adding smxx and rmxx.
• fixes from Jörg Sommer:
  • corrected a trace-message regarding maximum graphics-size; it used the similar ReGIS maximum size which might not be configured.
  • in do_select_regex, clear selection if there is no match. If the regex does not match anything around the cursor, the selection returned must be empty, otherwise the whole line is treated as a match. This way the command defined by exec-selectable will not be executed if there is no match.
  • modify limit in do_select_regex to include the character at the cursor in the match, making it easier to type something and then hit the key to trigger exec-selectable.
  • If exec-selectable or insert-selection is triggered by a mouse button click, the position of the mouse pointer should be used. This makes it easier to address any position on the window and it makes it possible to use the mouse, e.g., for applications such as mutt where you cannot move the cursor.
• modify DECRC to save/restore xterm's last-column flag used to control wrapping behavior rather than manipulating DECAWM (report/analysis by Mattias Engdegård).
• add configure option --enable-terminfo-env to use the value set by --with-own-terminfo for the $TERMINFO environment variable. That variable was set automatically for HPUX, but would be useful in other systems, e.g., for Solaris (request by Jeff Wieland).
• fix a race condition when setting up a signal handler to timeout if opening /dev/tty hangs (patch by Tobias Stoeckmann).
• review/cleanup resources which were not in the manual page (report by Maxwell Anselm):
  • add manual page description as needed.
  • drop resource name for menuBar, as unnecessary.
  • modify fallback numeric value for regisScreenSize resource to match that for maxGraphicSize.
• updated configure macros CF_ADD_CFLAGS, CF_CC_ENV_FLAGS, CF_GNU_SOURCE, CF_MATH_LIB, and CF_XOPEN_SOURCE from other program-changes.
• update config.guess, config.sub
• change “maximum screensize” assumed by resize to 9999x9999, to accommodate people using the Unreadable font.
• drop Utility from default value of --with-desktop-category (Debian #780176).
• widen the configure script pattern used for finding related ".desktop" files, including “Terminal”
• several minor improvements to font utility functions:
  • provide for later modification to implement font-sets by parsing the font resources as comma-separated lists.
  • parse -fn and -fa similarly, using “x:” and “xft:” prefixes for font name/family strings to distinguish between XLFD and Xft font specifications.
  • use loops to iterate over font classes
  • use getters/setters for font data to allow for on-demand lookups.
  • make the debugging trace for missing glyph less verbose since that interferes with the -report-fonts option.
  • refactor xtermLoadFont to make it clearer how some fonts are derived from others, e.g., bold, wide.
  • make the triggering and suppressing of font-warnings more consistent by storing the last state in the widget.
  • reduce font-warnings by checking for repeated warnings.
• add vttests/query-status.pl
• add vttests/closest-rgb
• add special case for displaying soft-hyphen if it happens to fall at the right margin, and omitting similar case such as the BIDI markers, where a zero-width character is neither a control character nor a combining character (Debian #844325).
• modify logic for OSC 52, manipulate selection data, to update the selection-time to include the latest X events. This fixes some cases where the selection was invalid, e.g., after an event due to focus-follows-mouse (report/testcase by Stephane Chauveau).
• revise macro CastMallocN as new macro TextAlloc to make explicit use of sizeof(char) (prompted by patch by Cade Foster).
• add “Mouse Ops” menu entry and related resources to allow runtime disabling/enabling of the mouse protocol escape sequences (discussion with Bob Proulx).
• improve discussion of mouse actions versus protocol in the manual (discussion with Bob Proulx).
• improve discussion of environment variables in the manual, pointing out where some features (such as termcap and the System5 COLUMNS and LINES variables) are used rarely, mainly to support legacy applications.
• add examples of translations resource for select/paste, and for font-size changes to the manual.
• minor reordering of some entries in ctlseqs.ms for consistency (report by Arran Ubels).
• add -s option to 256colors2.pl and 88colors2.pl, to demonstrate modifying the “system” colors 0–15.
• omit XFT_SPACING property from call to XftPatternBuild, to work around a bug in fontconfig for handling Google Go fonts, whose names sort in an order not expected by fontconfig, causing the request for a monospaced font to return italics, e.g.,
• modify minstall.in to improve a workaround added to the manual page in patch #182 to avoid having the C preprocessor used in the imake configuration strip out the comments in the character classes section (reports by Ted Unangst, Anthony J Bentley).
