v0.6.4
A large feature and bug fix release.
sciteco-0.6.4.tar.gzis the Automake-generated source tarball. Includes Scintilla and Scinterm.sciteco-0.6.4-pdcurses-win32.zipis a Windows 32-bit console build of SciTECO. Supports anything beginning with Windows 2000, Wine, etc.sciteco-0.6.4-pdcurses-win32a.zipis a Windows 32-bit "windowed" build of SciTECO. It's still a Curses aplication but runs in a GDI window. Has advantages and disadvantages compared to the true-console version. Binaries can be swapped between the two Windows packages.sciteco-curses_0.6.4-5_i386.debis an i386 Debian package of the ncurses port. This is definitely the best-supported port currently. This may or may not install successfully on your Debian(-based) Linux distribution.- Ubuntu users can download pre-built packages for many recent Ubuntu versions from the PPA.
Here is the complete change log:
The following change log summarizes changes introduced
by SciTECO releases compared to the preceding release.
Only changes relevant to users (build from source or
using a prebuilt binary) are included.
Entries marked with "(!)" might break macro portability
compared to the preceding release.
Version 0.6.4
18fe073 added PDCURSES_LIBS ./configure variable to overwrite the check for PDCurses
537b7b5 preliminary support for ncurses/win32. This port is not well
tested.
64ee414 implemented function key masking (context-sensitive function key macros).
The command line editing macros in fnkeys.tes will no longer insert
"garbage" into string parameters.
cb8411d,
c310c7d implemented automatic EOL translation support.
This means that SciTECO now properly supports editing files with
different line breaks. It especially simplifies editing files with
DOS/Windows line breaks and allows you to write portable macros that
are line break agnostic.
eee4f1a added "EL" command for setting/getting the current document's EOL mode
14ec511 also set window title on ncurses, by querying terminfo capabilities.
This feature is currently buggy.
34a4c7e ncurses: Fixed batch mode initialization in head-less environments
(where $TERM is unset). Interactive mode should no longer start in
headless or broken environments but report an error.
2a4acd6,
2c0e9f7,
4dced2c improved ncurses batch mode initialization.
Only relevant for UNIX/Linux: When SciTECO is run in batch mode,
it completely keeps away from the process' terminal device.
It no longer flashes the screen (was visible e.g. in rxvt-unicode).
7ceabb2 Curses UI: beep on error. This might also perform a visual bell or
nothing at all (depending on the terminal emulator).
b3acf28,
647e6eb added cool SciTECO icon (on Windows, it is the icon of sciteco.exe)
20cb9a7 added --no-profile command line option
1126007 added the <"I> conditional for checking whether a character is a
directory separator
(!)a0d1231 always normalize directory separators to "/" in the "*" Q-Register.
On Windows "*" used to contain Windows directory separators.
With the new behaviour it is easier to write portable macros.
67b846c added ./configure --enable-static-executables option
e88f9bb,
3db42f8 optimized user interface drawing.
Should also speed up the GTK+ UI.
10e4e27 fixed displaying of control characters in the "info" line (and window title)
4a4687c improved `sciteco --help` output
2a4e114 fixed m,nXq for m > n: this properly throws an error now instead of crashing
63c88b9 changed save point file format to .teco-<n>-<filename>~
Users should adapt existing VCS ignore patterns if necessary.
a3a340a fixed TAB completion of files in the current directory beginning with ".".
Not sure if this bug existed in v0.5.
2cfc358 added function key macro for Shift+DEL to fnkeys.tes:
Acts as a "reverse" backspace-key (depending on the state of the
^G modifier).
800bbd8 fixed function key handling on GTK UI.
Function keys are now properly ignored until they are enabled by setting
bit 6 of the ED flags.
a399be7 On UNIX/Linux with glibc, heap memory can be reclaimed
earlier when terminating a command line.
This means that your system will recover earlier after it began
swapping because SciTECO used too much memory.
8178f8d,
4aa51b9,
3373274,
ef82d22,
83ebaea,
482c0e7 Implemented re-insertion of rubbed out command lines.
This effectively implements SciTECO's version of Redo.
Rubbed out parts of the command line are still visible in grey.
The new "^G" immediate editing command can be used to
toggle the behaviour of the rubout commands from rubout (undo)
to re-insert (redo).
The "^G" toggle modifies other immediate editing commands as well.
It replaces the "^T" immediate editing command with "^G<TAB>^G".
b40fe86 implemented undo stack memory limiting (ticket #3).
The size of the undo stack is now approximated and limited.
An error is thrown and the current command fails if more than 500mb
are used by it. The limit is configurable (see "EJ" command).
This makes it harder to crash SciTECO by using up all the memory
due to infinite loops in interactive mode.
611bb22 fixed crashes when loop is closed (>) or continued (F>) without a
corresponding loop start (<) (ticket #3).
4624eeb,
c7b2da8 work around Scintilla character representation drawing bug.
This fixes too much space being allocated to control characters in the
SciTECO buffer view.
1b07f32 Scintilla: fixed tab stop calculation on Curses
This is included in the Scintilla mirror at https://github.com/rhaberkorn/scintilla-mirror
and thus in v0.6 source bundles.
(!)d24bc4a implemented support for different indention styles.
The TAB-command (^I) has been extended to insert indention characters
according to current Scintilla settings (SCI_SETUSETABS, SCI_SETTABWIDTH).
TAB has been made an immediate editing command in insertion commands
("I", "^I" but also search-and-replace arguments) to insert indention
characters by the same rules.
In old macros where "^I" was used for inserting the TAB-character,
"9I" should be used instead.
574d284 support filename auto completions with forward-slash directory separators on
Windows. Auto-completions will now use the last directory separator in
string that has been typed before auto-completing.
On platforms like Windows where both forward and backward slash separators
are possible, this makes a difference.
By default however, the platform-default directory separator is used.
613e8c9 Curses: support cycling through long lists of possible auto-completions
and optimized screen refreshing/redrawing
52ecff4 Curses: fixed formatting of popup windows
4377770 do not show possible completions for hidden files and directories
They are ignore during tab completion unless the beginning of the name
of a hidden file or directory has been typed.
I.e. "../.<TAB>" will still complete hidden files on UNIX.
(!)ad3d2f4 implemented pQq and :Qq commands
In other words, the "Q" command can now be used to index the
string part of a register and query its size without editing it first.
This breaks macro backward-portability since "Q" will no longer
ignore existing values on the stack.
Therefore the expression "QaQbK" must now be written "Qa,QbK".
ebf0440,
abda28b introduced $SCITECOCONFIG env variable, and set different default for
$SCITECOPATH on Windows.
$SCITECOCONFIG allows you to reconfigure the path where SciTECO looks
for the profile macro.
On Windows, these variables are initialized to paths relative to the
location of the sciteco.exe file. This keeps SciTECO self-contained on
Windows (unzip the release and go!) while allowing it to be added to
$PATH and used from any working directory.
The environment variables can be set explicitly, e.g. to set up
SciTECO for a MSYS or Cygwin environment.
The environment variables are always normalized to absolute paths.
On Windows, the profile macro is now called ".teco_ini" just like
on UNIX. You must rename existing "teco.ini" files or - better yet -
completely rewrite them.
e030c4e fixed memory leak in batch mode
1e5115b Added "E%" command to save a Q-Register's string contents to disk
without changing the current document.
"EW" can now also be used to save a Q-Register to disk.
14cc71e added "EI" command as a non-string-building variant of "I"
3e7ebb5 added "EU" command as a variant of the "^U" command with string building
characters enabled.
a6c13d7 allow setting the numeric part of the "*" register as an alternative to nEB
Allows a few useful idioms like "1U*" instead of "1EB$" and
"[* ! temporarily edit another buffer ! ]*"
6e5a611,
5b74ef5,
2900fcb,
d38df48 added a buffer session module (session.tes)
This can be used handle buffer sessions (i.e. restore the buffer ring
when starting up again).
It also includes macros like "session.git", "session.svn" and
"session.hg" to set up one session per VCS repository automatically.
a37daa8 added "EJ" command: return runtime properties
This may be used e.g. to query the number of buffers in the
ring. "EJ" or "1EJ" will return the number of buffers, while
"0EJ" returns the current user interface. You can use that
in the profile for instance to select different color schemes.
f279d24,
67bfd59,
427c9d1 added globbing command "EN"
It is called like classic TECO's "EN" command but behaves
differently.
28fd3db fixed rubbing out buffer edits ("EB") after a local Q-Register
has been edited. Not sure if this was present in v0.5.
59bbee9,
16a47e2 finally implemented the CLOSE and QUIT hooks.
These ED hooks were already documented but unimplemented.
The "CLOSE" ED hook is now executed before a buffer is removed
from the ring.
The "QUIT" hook is executed before SciTECO terminates in a batch
mode context. In other words, when quitting SciTECO shuts down
interactive mode and executes the "QUIT" hook.
"QUIT" hooks may be used to save buffer sessions.
(!)efa646d renamed ED hook register to "ED" and protect ED hook executions
In other words, to set up ED hooks, you must now configure
the Q-Register "ED", as in "@^U#ED{ !...! }".
ED hook executions are now protected, as if run by
"(nM[ED]^[)". This means that buggy ED hook macros can
no longer result in undefined side-effects of commands
that trigger ED hooks.
e909fb2 Throw error when a macro terminates while a local q-reg is edited.
This fixes possible crashes resulting from accessing freed resources.
f843a09 throw error when macro returns with an unterminated command
E.g. the macro "@^Um{Ihello}" will throw an error if executed
with "Mm".
(!)4282e7d allow a current buffer if we're editing a Q-Register.
This means that the Q-Register "*" contains the name of
the current buffer even if a Q-Register is edited.
c80c632,
d4f8fb3 new modular lexer (syntax highlighting) system
This includes configurable color profiles (colors/*.tes), one lexer
configuration file per language (lexers/*.tes) and automatic
loading of installed lexer configs.
Syntax highlighting can be set manually by executing
corresponding macros. E.g. to set C++ syntax highlighting
you can execute "M[lexer.set.cpp]".
The lexer library (lexer.tes), contains useful macros
for writing your own lexer configurations.
2542eb0,
e762a43,
2ee2ddd,
38fcf6d Improved overall performance by avoiding unnecessary virtual method calls
0f413b0 Adapted sample .teco_ini: margin setup must be done for every new document
(!)8be99d3 Every SciTECO buffer has its own Scintilla view now.
This fixes the rubout of the "EB" command since lexer styles
no longer have to be restored.
Therefore, it allows writing (bug-free) ED-hooks that setup
syntax highlighting.
Scintilla configurations that should apply to all buffers must now
always be made on all buffers (i.e. their views).
Q-Registers still share a single Scintilla view.
d9f04a7 Building from source: enable bootstrapping by default
The language changes frequently. This ensures that an up-to-date version
of SciTECO is built to run the macros included in the source packages.
This will NOT work when cross-compiling SciTECO.
You must first build a version for the build system and cross-compile
with ./configure --disable-bootstrap
468cb19 added ^# (XOR) operator
3006be5 fixed number formatting for radix > 10.
This fixes the "\" command and "^E\" string building character
if the radix is set higher than 10, e.g. "16^R".
0987ca8 Revised function key macros in fnkeys.tes
This fixes glitches when movement keys are used that would move "dot"
off-page.
Also, the "HOME" key binding will jump to the beginning of the line
skipping any leading whitespace. A second press will jump to the real
beginning of the line (like "0L").
The "UP" and "DOWN" key bindings try to keep the column of the previous
line.
(!)5e1ad77 extended "^U" command:
allow setting and appending of strings and characters from the expression stack.
A colon-modified form ":^U" appends characters from the expression stack
and its string argument.
This means that integer arguments no longer "pass through" the ^U command.
It is now more like TECO-11's ^U, but more powerful.
7b9d5ba support new "~" conditional: useful for implying default parameters in macros
E.g. the conditional expression "~1' implies the value 1.
(!)fa12867 revised "U" command: fail if no argument is provided
This means that expressions like "Ua" are no longer valid and
must be written "1Ua" instead.
The expression "-U" is still allowed as a short-hand for "-1U".
Also, now there's ":U" which returns a condition code if the
argument is missing instead of throwing an error.
01a4211 Clarify `symcasecmp` macro in string.tes (documented it)
d59ba50 fixed undoing of initial TECO buffer/document changes
a475ea8 fixed rubbing out local Q-Register modifications in macro calls
1c3b2a9 fixed crashes when pushing operators without corresponding operands.
Instead an error is thrown.
This fixes expressions like "++", "+1+", etc.
3c1125c Basic TAB-completion support for EC and EG commands
7746480 added "EG" command: pipe from buffer into Q-Register
1aab71c,
20d1f0e,
acc911a implemented "EC" command (execute operating system command).
This requires at least libglib v2.34 on Windows.
On UNIX, pre-v2.34 versions are supported as a workaround (ticket #2).
(!!!)a395c9d changed syntax for long Q-Register names: use [] brackets instead of {}
This means that expressions like "M{macro}" must now be written
"M[macro]". This will break all existing macros!!!
On the other hand, it improves readability of SciTECO macros.
06d0bac fixed reversing the "EW" command when used to save a file with another
name (save as)
b62f736 depend on Scintilla v3.5.2 and Scinterm v1.5 (included in
tar balls). This brings many new curses features, e.g. scroll bars
and new Scintilla lexers. You should refer to the Scintilla v3.5.2
documentation when setting up SciTECO.
39406f4,
a27b5d4,
30d8bf3 automatically build Scintilla as part of SciTECO's build system:
this should simplify building SciTECO from source for new users.
Scintilla is now automatically checked out when cloning the Git repository
and it is included in every source tar ball.
af17bd7 fixed crash on unexpected semicolon (break from loop)
d94b188 fixed enclosing SciTECO expressions in braces that do not generate any
values. E.g. this fixes "1<()>".
54de1dc build system improvements
f6fa45e fixed array freeing using delete. Could have resulted in crashes.
793f801 fixed severe bug related to referencing temporary values.
Fixes many build issues and possible memory corruptions.
dbd252c ncurses: fixed info bar at startup
4ae59fd avoid deprecated glib functions
e5563f8 report argument stack overflows as errors
5e92818 Division by zero no longer crashes SciTECO but throws an error.
707acef,
8046e11,
78ad52e improved and fixed error reporting in general
1f8d558,
abfabda try to recover from out of memory conditions.
This is ultimately doomed to fail ;-)
d374448 added support for TECO stack tracing.
Errors in batch mode will now print a TECO stack trace.
0674f29,
6d4668b added EMCurses/Emscripten support.
Only really "required" by the live demo at http://sciteco.sf.net/
de616e3 Fixed compilation of the GTK+ interface
(!)f510c10 only allow command-line replacements when actually editing the replacement register.
This helps avoiding to rubout the entire command line by accident.
c5c24b0 updated lexer config: CMake and XML lexing
6f7694e Fixed building on non-C locales (Thanks to Martin Roedel!)
