* lexer.checkheader is therefore case-sensitive now as well
|
|
* We cannot call it "." since that introduces a local register
and we don't want to add an unnecessary syntactic exception.
* Allows the idiom [: ... ]: to temporarily move around.
Also, you can now write ^E\: without having to store dot in a register first.
* In the future we might add an ^E register as well for byte offsets.
However, there are much fewer useful applications.
* Of course, you can now also write nU: instead of nJ, Q: instead of "." and
n%: instead of "nC.". However it's all not really useful.

non-control characters, but to the literal caret, followed by c
* For instance `^$` would insert two characters.
* The alternative would have been to throw an error.
|
|
* This would actually causes crashes when trying to format numbers.
* The ^R local register has a custom set_integer() method now,
so that the check is performed also when using nU.^X.

^R now (refs #17)
* This way the search mode and radix are local to the current macro frame,
unless the macro was invoked with :Mq.
If colon-modified, you can reproduce the same effect by calling
[.^X 0^X ... ].^X
* The radix register is cached in the Q-Reg table as an optimization.
This could be done with the other "special" registers as well, but at the
cost of larger stack frames.
* In order to allow constructs like [.^X typed with upcarets,
the Q-Register specification syntax has been extended:
^c is the corresponding control code instead of the register "^".
|
|
* Usually you will only want -^X for enabling case sensitive searches
and 0^X for case-insensitive searches (which is also the default).
* An open question is what happens if the user sets -^X and then calls
a macro. The search mode flag should probably be stacked away along
with the search-string. This means we'd need a ^X special Q-Reg as well,
so you can write [^X[_ 0^X S...$ ]_]^X.
Alternatively, the search mode flag should be a property of the
macro frame, along with the radix.

filenames containing ASCII 27
* You can now set a per-file tab style, that differs from the defaults established
in the ED hook.
This is important especially since we do not yet support per-project .teco_ini
scripts where you could establish differing policies depending on the VCS repository.
(The latter would be easy to implement, but we cannot currently easily extend the
existing ED hooks.)
* It's unlikely that files contain an ASCII 27, but not impossible.
Therefore we now use ASCII 0 (^@) as a terminator.
This indeed be safe under UNIX.
Even better would be a string building construct for escaping ASCII 27 ($), though,
as that would work with arbitrary bytes.

* should also fix Win32 nightly builds
* Even though we weren't using main's argv, but were using glib
API for retrieving the command line in UTF-8, newer MinGW runtimes
would fail when converting the Unicode command line into the system codepage
would be lossy.
* Most people seem to compile in a "manifest" to work around this issue.
But this requires newer Windows versions and using some Microsoft tool which isn't
even in $PATH.
Instead, we now link with -municode and define wmain() instead, even though we still
ignore argv. wmain() proabably get's the command line in UTF-16 and we'd have to
convert it anyway.

non-relocatable binary)
* This was accidentally installing into $bindir/usr (usually /usr/local/bin/usr/...)
You might want to check whether SciTECO accidentally installed something there.

The next release will include almost exclusively bug fixes.

|
* The line drawing algorithm currently works only with tbl, though.
* Also only straight lines are currently supported.
* This was meant for rendering presentations in SciTECO - it's not currently
used or planned to be used in the manpages.
Although we might well add pic graphics to the manpages in the future.

This could theoretically be used to apply Scintilla styles not natively and easily supported by grosciteco,
eg. different fonts and font sizes.

not found' error
* This is important with gotos in loops as in <@O/x/> where, we would otherwise
get a confusing "Unterminated loop" error.
* This in particular fixes the error thrown in grosciteco.tes when encountering
a new unknown command.

characters by unicode, ie. typesetting of most non-latin text
* This was broken at least for characters that happened to contain hexadecimal digits > 9
since "D does not detect hexadecimal digits.
|
|
* We just passed the length in glyphs to SCI_SETSTYLING.
|
|
* The program exit code will usually not signal failures since they are caught earlier.
* Therefore, we always have to capture and check stderr.

characters in Q-Register)
* It was initialized only once, so it could inherit the wrong local Q-Register table.
A test case has been added for this particular bug.
* Also, if starting from the profile (batch mode), the state machine could be initialized
without undo, which then later cause problems on rubout in interactive mode.
For instance, if S^EG[a] fails and you would repeatedly type `]`, the Q-Reg name could
grow indefinitely. There were probably other issues as well.
Even crashes should have been possible, although I couldn't reproduce them.
* Since the state machine is required only for the pattern to regexp translation
and is performed anew for every character in interactive mode,
we now create a fresh state machine for every call and don't attempt
any undo.
There might be more efficient ways, like reusing the string building's
Q-Reg parser state machine.
|
|
* A test case has been added, although it might have been accidental
that on caused crashes.

* You can now specify `--with-scitecodatadir` as a relative path,
that will be interpreted relative to the binary's location.
* Win32 binaries already were relocatable, but this was a Windows-specific
hack. Win32 binaries are now built with `--with-scitecodatadir=.`
since everything is in a single directory.
* Ubuntu packages are now also built `--with-scitecodatadir=../share/sciteco`.
This is not crucial for ordinary installations, but is meant for AppImage creation.
* Since AppImages are now built from relocatable packages,
we no longer need the unionfs-workaround from pkg2appimage.
This should fix the strange root contents when autocompleting in
AppImage builds.
* This might also fix the appimage.github.io CI issues.
I assume that because I could reproduce the issue on FreeBSD's
Linuxulator in dependence of pkg2appimage's "union"-setting.
See https://github.com/AppImage/appimage.github.io/pull/3402
* Determining the binary location actually turned out be hard and
very platform-dependant. There are now implementations for Windows
(which could also read argv[0]), Linux and generic UNIX (which
works on FreeBSD, but I am not sure about the others).
I believe this could also be useful on Mac OS to create app bundles,
but this needs to be tested - currently the Mac OS binaries are
installed into fixed locations and don't use relocation.

string cells
Found thanks to the "infinite monkey" test.
|

Supposing that any monkey hitting keys on a typewriter, serving as a hardcopy
SciTECO terminal, will sooner or later trigger bugs and crash the application,
the new monkey-test.apl script emulates such a monkey.
In fact it's a bit more elaborate as the generated macro follows the frequency
distribution extracted from the corpus of SciTECO macro files (via monkey-parse.apl).
This it is hoped, increases the chance to get into "interesting" parser states.
This also adds a new hidden --sandbox argument, but it works only on FreeBSD (via Capsicum)
so far. In sandbox mode, we cannot open any file or execute external commands.
It is made sure, that SciTECO cannot assert in sandbox mode for scripts that would
run without --sandbox, since assertions are the kind of things we would like to detect.
SciTECO must be sandboxed during "infinite monkey" tests, so it cannot accidentally
do any harm on the system running the tests.
All macros in sandbox mode must currently be passed via --eval.
Alternatively, we could add a test compilation unit and generate the test data
directly in memory via C code.
The new scripts are written in GNU APL 1.9 and will probably work only under FreeBSD.
These scripts are not meant to be run by everyone.

jumping to the beginning of the macro)
* I am not sure whether this feature is really that useful...
* teco_machine_main_t::macro_pc is now pointing to the __next__ character to execute,
therefore it's easier to manipulate by flow control commands.
Also, it can now be unsigned (gsize) like all other program counters.
* Detected thanks to running the testsuite under Valgrind.
|
|
* Any memory error will let the test case fail with code 66.
* You can also call
make check TESTSUITEFLAGS="--valgrind"
* There is no program test for Valgrind in configure.ac for the time being.
`valgrind` must be in $PATH.
* All CI testsuite runs under Ubuntu are now with Valgrind.
|
|
* There was some boilerplate code missing in teco_state_search_all_initial(),
that is present in teco_state_search_initial().
* Perhaps there should be a common function to avoid redundancies?
* This will also fix the initialization of the string argument codepage for <N>.

* Has been observed on PDCursesMod/WinGUI when pressing CTRL+Shift+6 on an US layout.
I would expect code 30 (^^) to be inserted, instead PDCurses reports two keypresses (6^^).
The first one is now filtered out since this will not be fixed upstream.
See also https://github.com/Bill-Gray/PDCursesMod/issues/323
* Since AltGr on German layouts is reported as CTRL+ALT, we must be careful not to filter those
out as well.
* This is active on all PDCurses variants - who knows which other platforms will behave similarily.
* You still cannot insert code 0 via CTRL+@ since PDCurses doesn't report it, but ncurses does not allow that either.
This _could_ be synthesized by evaluating the modifier flags, though.
|
|
* I am not entirely sure whether it would be safe to bundle
api-ms-win-core-synch-l1-2-0.dll or bcryptprimitives.dll,
so I won't upstream this change yet.
* Should fix GTK/Win32 nightly builds.
|
|
* Fixes the test suite on PDcurses/Win32 and therefore CI builds.
* Should be necessary on UNIX as well since later on, we would access
cmdline_window, which is not yet initialized.
I didn't see any errors in Valgrind, though.

|
* Supports all immediate editing commands.
Naturally it cannot emulate arbitrary key presses since there is no
canonic ASCII-encoding of function keys.
Key macros are not consequently also not testable.
The --fake-cmdline parameter is instead treated very similar to
a key macro expansion.
* Most importantly this allows adding test cases for rubout behavior
and bugs that are quite common.
* Added regression test cases for the last two rubout bugs.
* It's not easy to pass control codes in command line arguments in
a portable manner, so the test cases will often use { and }.
Control codes could be used e.g. by defining variables like
RUBOUT=`printf '\b'`
and referencing them with ${RUBOUT}.

* This was a regression introduced in 41ab5cf0289dab60ac1ddc97cf9680ee2468ea6c,
which changed the semantics of teco_doc_undo_set_string().
* Removed undo_append_string() Q-Reg virtual method.
append_string() now does its own undo token emission, so that we can
defer the teco_doc_undo_edit() after the point that the document
was initialized. This is important, so that we can configure the
default encoding on new registers.

* detected under FreeBSD
* It turns out that it's unsafe to make the GIOChannel blocking
even though the application has already terminated and the channel
should be closed automatically.
The channel does not report EOF, but instead we have to look for
zero reads - in complete contrast to the behavior on Windows.
Apparently, it's very tricky to use this API correctly
(ie. it sucks).
* fixup to e9bef20a8ad89d304fe3e8fafa00056d22de2326
|
|
* We now recreate the event loop with every call since
it turned out that the idle watcher wouldn't be invoked
after the event loop has been quit once.
This at least fixes interruption of ECbash -c 'while true; do true; done'$.
* Unfortunately, ECping -t 8.8.8.8$ still cannot be interrupted
(unless you manually kill the process from the task manager).
|
|
* This API behaves very strangely and differently compared to UNIX/X11.
When getting, it returns a trailing null for all clipboard contents
(unless the clipboard is empty) and when setting, we apparently have to include it as well.
At least since we cut it off when getting.
Even more strangely, setting without the trailing null did work
when pasting in external apps. (How they know when it's safe to throw
away the trailing null is mysterious.)
* In other words, this fixes X~G~.
|
|
* This has only ever observed on Win32, probably because the spawning
behaves very differently.
* The stdout watcher could be invoked even after removing the source,
so we must be secured against it - this was causing some overflows
and invalid reads.
* Also, teco_eol_reader_convert() could return 0 even after process
termination, which would sometimes result in too few bytes being
inserted.
This could be provoked relatively easily by invoking ECdir$ repeatedly.
