VILE (Vi Like Emacs)

July 2005, vile 9.5 is released. Highlights since 9.4 (aside from bug fixes): General changes: + syntax filters can now be dynamically loaded. This allows the main executable to be smaller, and is faster than external filters. Loadable filters are configured using the "--with-loadable-filters" option to configure script. This works for several platforms using gcc. + add configure script option for largefile support, change buffer size datatypes an unsigned type to allow for reading files larger than a signed value would allow. + modify historical-buffer to allow tab/back-tab to cycle through the first 9 buffers, solves the problem of seeing more than the first few possibilities on the message line. Toggling with the repeated '_' selects the first buffer shown. + modify name-completion to allow completion of filenames containing a '$'. + relax a check in ":w" by checking if the given name differs from the current filename. If so, do not require ":w!" to write a readonly file to a different location. This allows one to reuse the filename history for ":w". + modify special treatment of "#" which prevents it from being shifted with ">>" by disabling that when cindent is unset. + add a few ex-commands: nu, j!, wq! + modify statevars.c to make read/write of $title consistent, i.e., will warn that it cannot be set in the termcap configuration. + modify [Messages] buffer so that it is only invisible, not a scratch buffer. The latter makes it be automatically removed after viewing and closing the window. + add pattern for "ant" (Java make-program) to a few of the patterns in finderr.c + modify PromptAndSet() to allow a cancelled prompt for variable's value to store an ERROR token, which can be tested in scripts with &error. + split-out modes.rc from filters.rc to make configuration more flexible, e.g., for configure --disable-filters. + modify minubuffer editing to allow one to use ^Ga to toggle miniedit mode and append to the buffer shown from a previous command rather than having it erased. + modify name-completion for majormode names used as macro parameters to use the long name (with "mode" ending) rather than the short name, for consistency. + modify perl.xs to allow for $VILE_LIBDIR_PATH to be a list of paths. Only add the corresponding xxx/perl names to @INC if they correspond to a real directory. + change minimum/maximum repeat counts for regular expressions from a byte to an integer. + modify interpretation of "~local", "~with", "~elsewith" and "~endwith" so they are within the normal "~if"/"~endif" hierarchy. + modify minibuffer editing to shift the display left/right as needed after doing the initial tab of a name-completion, in case that left the cursor position past the end of the line. + add experimental plugin support and example. Locale Improvements: + workaround for broken locale table on Solaris8 and Windows2000, etc., which shows tab as both as printable and a control character. The ISO C standard states that control characters are not printable. + extend workaround for UTF-8 locale in termcap driver to translate UTF-8 input to Latin-1. + improve/extend checks for locales which correspond to 8-bit character encoding, resetting to POSIX locale (ASCII) if the nl_langinfo() function returns a value that does not look like ASCII or ISO-8859-x. This change applies to the termcap/terminfo and X11 drivers. + show locale and encoding values in the header of the [Printable Chars] buffer. + add $encoding and $locale variables to show what vile's internal 8-bit encoding and locale are set to. + turn on locale feature on win32 New Commands: + add macro "which-menu" to which.rc, which shows the locations that xvile checks for a menu-file. + add macro "show-each-buffer" (file showeach.rc), which splits up the screen into equal chunks to display as many of the non-scratch buffers as possible. + add macro "which-filter" to show which locations would be checked for an external filter. If the filter happens to be built-in, this is also noted, in the message line. + improve "eval" command, provide for mixture of functions and other tokens which are passed to the script interpreter. + modify SpellFilter macro to use the results from [Filter Messages] with the error-finder to step through the misspellings. + add macro "show-filtermsgs" to show syntax filter messages, setting the list to the error-buffer to provide simple stepping through the errors which are found. + add commands "popup-buffer" and "popdown-buffer", which open/close windows for the given buffer rather than changing the current window to show a different buffer. The "popup-buffer" command is a wrapper for the existing logic used for help and similar commands. The "popdown-buffer" command differs from "delete-window" by closing all windows for the given buffer. + add command "for-buffers", which performs the same command for the specified buffers. New Modes: + add "reader-policy" mode, which allows one to control whether vile will fall-back to line-by-line reading if it encounters an error. + add mode "for-buffers", which specifies whether kill-buffer (and for-buffers) command use globbing or regular expressions. + add "filtermsgs" mode, for built-in filters to report syntax errors into [Filter Messages] buffer so that one may use the error finder to locate these. + add mode "ignoresuffix", which tells vile to strip the given pattern from a filename before matching majormode suffixes against it. + add mode "showchar", which turns on a field in the modeline that tells what the character value is at the current editing position. New Variables and Functions: + add new operators to make it simpler for macros to check for features: "&isa", "&classof" and "&mclass". + add "&match" and "&cmatch" functions for checking if a given regular expression matches a string. + add "$error-tabstop" variable, to allow changing the tabstop value used when interpreting "%C" results in the error finder. Most programs assume 8, and that does not work well when editing buffers with other tabstops such as 4. + add "$goal-column" variable for debugging. Syntax Filters: + modify ".table" command in filters parsing to read the user's color definitions, e.g., from .vile.keywords, as is done in a ".source" command. + add a ".brief" to filters parsing, which uses "?" to match zero or all of the following characters, in constrast to ".abbrev" which uses "*" to match zero or more of the following characters. + several new majormodes, with corresponding syntax filters: + ".jsp" files are really (close to) a variety of HTML files. Add simple support for JSP in htmlfilt.l + add iss-, nsis- and ini-modes + add lispmode, to use vile-lisp-filt. + add nmakemode, for special cases such as M$'s ".dsp" files. + add syntax filter for AutoIt version 3 and majormode au3mode. + add syntax filters for iss- and ini-modes. + add vbsmode using ".vbs" suffix based on basmode. + extend suffixes for several majormodes: + add ".asp" to jspmode suffixes + add ".cls" filetype for vbmode, add symbols for Visual Basic class modules to vb.key + add ".dcl" filetype for dclmode. + add ".el" to suffixes for lispmode. + add ".hpp" to suffixes for cppmode. + add ".jad" suffix for javamode for Java Disassembler. + add ".mm" to nroff mode. + add ".ph" and ".pph" to esqlmode suffixes. + add ".shar" to shmode suffixes. + add ".termcap" and ".terminfo" suffixes for tcmode and timode + add ".tic" as a suffix for timode. + make "TODO" a txtmode file. + modify pattern for logmode to allow filenames such as gmake.out + add a mode-pathname setting for cppmode, so files under (for example) /usr/include/g++ will be treated as C++. Newer C++ headers have no suffixes. + add an "-s" option to c-filt.c, for JavaScript (to support jsmode). Use this to control whether to allow regular expressions in certain cases. + modify ShowFormatted macro to support "-mm" macros. + modify spellflt.l to allow it to be used in winvile, using npopen, as a built-in filter. + rewrote pascal syntax filter in lex, adding highlighting for numbers, and TurboC, Delphi comments. + modify cppmode's suffixes to look for .C, .H and .CC only on systems where filenames are case-sensitive. + split up the majormode "suffixes" into suffixes, mode-filename and mode-pathname to make it clearer how to associated regular expressions with the filename for majormodes. + change highlighting for misspelled words to Error class. + add environment variable VILE_SPELL_FILT to vile-spell-filt, to allow overriding the compiled-in program and options used for performing the lookup. + many improvements to parsing and highlighting in existing filters (see CHANGES). X11 changes: + add --disable-imake option to configure script, from xterm. + modify xvile's wheelScrollAmount resource to scroll by pages if the resource value is negative. + revise lookup for xvile's menu file to look for dotnames in the current and home-directories, while non-dotnames may be found there and in $HOME/.vile and on $startup-path. Combine this with changing the default for $menu-file back to ".vilemenu" as documented rather than "vilemenu.rc". The latter name is used in the non-dotname locations if $menu-file is a dot-name. Win32 changes: + several changes to allow winvile to remember recent files and folders + winvile remembers up to 20 of the files it has recently opened/created (feature disabled by default). + winvile remembers up to 20 of the folders it has recently visited via an implicit or explicit cd (feature disabled by default). + Remembered files/folders are accessible and "replayable" from winvile's system menu. + Two new modes: recent-folders and recent-files specify maximum number of folders/files that may appear in winvile's system menu. Range is 0-20; a value of 0 disables feature. + Two new commands: purge-recent-folders and purge-recent-files clear the list of folders/files that appear in winvile's system menu. + modes and commands work in console mode (minimizes conflicts when sharing a single vile.rc), but the files/folders that console vile accesses are _not_ remembered. + improve the winvile resize/status window: + make resize window wide enough to show geometries that exceed 99 columns + make resize window continually center itself over the editor's frame (NT and XP only). + modify dequoting of winvile's command-line in ntwinio.c to allow for quoting to be within parameters, e.g., winvile +"100" makefile + reenable SHIFT+INSERT in the win32 mini-buffer (for both vile.exe and winvile.exe). Unfortunately, the cygwin shell eats SHIFT+INSERT for console vile (mini-buffer input only). now, it's once again possible to: $ vile somefile /<shift+insert> <- search for string sitting on clipboard + modify environment variable lookup for win32 to look in the registry for the VILE* environment variables: VILEINIT VILE_HELP_FILE VILE_LIBDIR_PATH VILE_STARTUP_PATH VILE_ERROR_ABORT This change is made to make it more easily installable; Windows changes to environment variables apparently do not take effect until the machine is rebooted. Registry changes take effect immediately. + add package script for winvile using Inno Setup. + improve cursor display in winvile: + when selecting text, show I-beam cursor. + when selecting a movable mode line, show a double-headed, north-south cursor. + when moving the mouse over a movable mode line, show a double-headed, north-south cursor. + don't allow mouse capture if the left mouse button is pressed in the area encompassing the editor's last two lines (message line and nonmovable mode line). Don't allow mouse capture if the left mouse button is pressed on movable mode line. Corrects long-standing winvile bugs. + add graphical change-directory to [win]vile via new command "wincd". The graphical change-directory is also accessible via winvile's system menu and right mouse popup menu. + ensure that files created via winvile's "Save As" and vile's ":f" commands are remembered in winvile's "Recent Files" list. + make filename completion with cygwin ignore case. VMS changes: + add VMS mode record-attrs, modify logic in vms_creat() to use this information to make the default VFC files written from DCL editable. Those use PRN (print file format) record attributes. + modify which.rc to use &pcat rather than $pathname-separator, since the latter is ambiguous on VMS. + modify infer_majormode() to work with VMS pathnames. + correct logic for VMS pathnames so that a directory buffer will, as on Unix, give the same buffer name as the directory leaf. + improve fakevms test-driver and related OPT_VMS_PATH code for VMS pathnames, making name-completion work for VMS pathnames on Unix. + modify catnap() function to use IEEE floating point on IA64, since that platform does not support F-floats. + modify vmsbuild.com and descrip.mms to work with IA64. ------------------------------- $Header: /usr/build/vile/vile/RCS/README,v 1.93 2005/07/25 23:29:24 tom Exp $ -------------------------------
