Changes:
20211212 (v)
> Lois Mansot
+ corrected range for &random function.
+ move the reframe_cursor_position() in update() to ensure that $cwline
is shown correctly when viewing [Variables] while showvariables is
set.
> Mark Robinson:
+ modify c-filt.c
+ include the quote chars in the literal colouring for C/C++/Java/etc
to make it the same as most other syntax highlighting
+ add backquote "`" as a quoting character for JavaScript, e.g., for
multi-line quotes.
+ highlight embedded "${xxx}" markers in JavaScript strings using the
Ident2 color.
+ modify sh-filt.l
+ improve parsing of the beginning of here-document to allow for
here-documents piped to programs, e.g.,
cat <<EOF | pr
something
EOF
or
cat <<EOF && date
something
EOF
+ do not treat "#" as a comment marker if it is adjacent to nonblank
text.
> Stephan Schulz:
+ add popup-choices mode (Savannah #58999)
> Tom Dickey:
+ eliminate filename conflict between vile/xvile in test-packages for
FreeBSD ports, e.g., xvile's vileget becomes xvileget.
+ suppress some of the gcc warnings due to perl header-files.
+ updated plink.sh, from xterm, to work around poor performance of gcc
on Fedora.
+ modify perl scripts to use /usr/bin/env to locate the perl program,
and eliminate sinstall.sh
+ modify curses-driver to support italics, e.g., as in ncurses 6.
+ apply Xaw header-fix for XawPlus, neXtaw and Xaw3dxft.
+ use Xaw3d menu-headers for x11vile.h and x11menu.c (FreeBSD #186420).
+ replace Header keywords with Id, to make Git-snapshots match.
+ continue development of xftplain.c (--enable-freetype). The current
driver is able to display a single TrueType font using Xft. The
menu entries for the bitmap-fonts are replaced by a single menu with
sizes.
Some of the remaining issues:
+ provide conversion for X displays other than 24-bit TrueColor
+ implement fallback fonts, i.e., --enable-fontsets
+ modify configure script to check for ssp library, needed for some
misconfigured libraries when cross-compiling to MinGW.
+ fix a case in vile-manfilt where cur_line may not have been allocated
before first use.
+ update configure script to work with _Noreturn changes in ncurses
20210320 development version.
+ modify makefile.in, wrapping cd commands in a subshell to work around
"jobs" misfeature of pmake.
+ improve c-filt.c support for JavaScript
+ handle ranges, i.e., to avoid stopping on "/"
+ check for regex after ":"
+ add m,s,u,y to permissable flags ending regex
+ quoting-fixes in autoconf macros, per shellcheck warnings.
+ add check for 'U' in read_quoted() needed to make ^VUxxxx work.
+ modify lins_chars() to handle a case where a script inserts a UTF-8
character (report by Thomas Dupond).
+ modify configure/makefiles to support ".PHONY" feature.
+ change configure/makefiles to use ARFLAGS rather than AR_OPTS
+ change configure --with-warnings to --enable-warnings for consistency
with other configure scripts, using recent changes in that to filter
gcc -Werror options to avoid breaking configure checks.
+ fix a few build problems with --disable-extensions
+ split-out x11plain.c, to start work on TrueType font support in xvile
+ modify configure script to allow clang to support loadable filters,
since recent configurations work.
+ add/fix NetBSD pkgsrc-files for 9.8u
+ update FreeBSD package-files for 9.8u
+ update config.guess, config.sub
