* The scinterm submodule temporarily points to my own fork.
* This is necessary for the aspell macro on Curses.
See https://github.com/rhaberkorn/sciteco/wiki/Useful-Macros#spell-checker
* See also https://github.com/orbitalquark/scinterm/pull/19

* This is optimized for Groff, but works for Heirloom Troff and Neatroff as well.
Currently, the Heirloom and Neatroff requests are just added ontop of the Groff
ones. Theoretically, we could also try to separate the keyword lists into
a base K&R set with Groff, Heirloom and Neatroff ontop.
* The lexer necessarily has many restrictions, as Troff is fundamentally unparseable
(like classic TECO) and needs a lot of per-request knowledge.
* The "*.mm" extension has been removed from the lexers/cpp.tes.
I don't know what language this was for, and I prefer `*.mm` files
to be considered Troff.
* Temporarily changed the lexilla submodule URL.
The corresponding Lexila lexer is in the process of being upstreamed.
Once it is, I will probably revert the submodule to the official repository,
as the "troff" branch is not stable (can be rebased).

* Since they blacklist Pango among other things, it would use the Pango from the host system with the glib from the AppImage,
which resulted in a version mismatch on Linux Mint 21.1.
* It is now confirmed to work at least on Linux Mint 21.1.
* The Curses AppImage still bundles libglib as SciTECO should be the only thing referencing its functions.

* MacOS packages are now built on macos-12 since macos-11 has been deprecated.

numbers now
* Instead of TECO_OP_NEW, there should perhaps simply be a flag of whether `,` was used.
|
|
* in fact, with a negative exponent the previous naive implementation would even hang indefinitely!
* Now uses the squaring algorithm.
This is slightly longer but significantly more efficient.
* added test cases
|
|
* It's generally a bad idea to pass backslashes as a glyph in macro arguments, even as `\\`
since this could easily be interpreted as an escape.
* Instead we now always use `\[rs]`.
|
|
* gboolean cannot be used since it is a signed type
* bool is still more readable, even though we mostly use glib typedefs.
* AFAIK the glib types are deprecated, so sooner or later we will switch
to stdint/stdbool types anyway.
|
|
* This is the same variable used by gtk3-nocsd, but we will now work
even without preloading any libraries.
Also, it turns out that gtk3-nocsd does not ship as a FreeBSD port
and hasn't been updated in a long time.
* Setting this in .teco_ini wouldn't have been easy since the
teco_interface_init() is called before any TECO code.
Also, you might not even want disable this globally but depending
on the window manager.
* Therefore, you are advised to `export GTK_CSD=0` in ~/.xsession.
* The --no-csd command line option is kept for the time being,
but probably serves no more purpose.
|
|
* Also turns out, I will have to use gtk_window_set_icon_list().
* This fixes icons in tabbed and st (when embedding SciTECO).

|
* Horizontal movements (left/right cursor keys) establish the current column
and vertical movements (up/down) will try to keep on that column.
* This has long been problematic in SciTECO as it requires state that gets
reversed when the command line replacement takes place.
* I experimented with encoding the current horizontal position into the braced
movement operations as in (123C5U$), but I decided that this was clumsy and
I generally did not want these expressions to become even larger.
* Instead I decided to add some minimal support to the C core in the form of 4EJ
which is like a number register only that it does NOT get reversed on rubout.
This is exploited by the fnkeys.tes macros by storing the current position
beyond replacements.
* In theory, this should be a property of the document, but we cannot easily
store custom parameters per document.
So instead, there is just one global variable.
When editing another buffer, it gets reset to .ESGETCOLUMN$$.
sample.teco_ini has been updated.
* The current X position only makes sense in the context of fnkeys.tes, as
TECO commands like <C> are not necessarily "horizonal" movements.
For the same reason, the core does not try to initialize 4EJ automatically
when editing new buffers.
It's entirely left to the TECO macros.
* The commandline replacement is more robust now as it checks braced
expressions at the end of the command line more thorougly.
It will no longer swallow all preceding braced expressions.
Only if they are at least 4 characters in length and end in `C)` or `R)`.

FreeBSD ports tree
* see https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=276492
* also the license is GPLv3+ to be precise
|
|
* Works only in Gtk of course and only in the parser start state.
* Since its side effects can neither be reversed, nor does it have any side effects on the editor state,
we can completely rub it out.
* Currently, it will only affect the current buffer and only the text area.
It would be trivial to apply the zoom to the commandline widget as well (FIXME?).
There is currently no way that the zoom value or any font size could be passed to the CSS, though.
So the auto-completion overlay could only be zoomed if Gtk supports a zoom factor as well.
|
|
* was introduced in e7867fb0
|
|
(-Wsingle-bit-bitfield-constant-conversion)
* gboolean is defined as gint which is a signed type.
A gboolean 1-bit-wide bitfield cannot have the values 0 and 1 but only 0 and -1.
* This wasn't practically a bug unless you would try to compare one of those bitfields
with TRUE.
* All of those bitfields are now guint, even though this is less self-documenting.
|
|
* This port is quite basic and does not yet allow building Gtk versions.
|
|
* passing an empty command string down to the shell would always do nothing,
so it doesn't make sense to support that.
* for the time being, we generate a proper error
* in the future, it might make sense to define some special behavior like repeating
the last command - but EC does not currently save the command line anywhere.
* The generated documentation is currently ugly (FIXME).
mandatory parameters are not properly detected by tedoc and we cannot keep apart
Q-Registers from mandatory parameters either.
Also, we should allow <param> markup in command summaries.
|
|
* The lexer scripts are not installed if the LEXILLA option is disabled,
so they need to be excluded from pkg-plist.
|
|
* The plain text format is deprecated.
* Thanks to Bob Eager.
|
|
* This was setting only the teco_doc but wasn't calling the necessary
set_string() methods.
* The idiom [$ FG...$ ]$ to change the working directory temporarily
now works.
* Similarily you can now write [~ ^U~...$ ]~ to change the clipboard
temporarily.
* Added test suite cases. The clipboard is not tested since
it's not supported everywhere and would interfer with the host system.
* Resolved lots of redundancies in qreg.c.
The clipboard and workingdir Q-Regs have lots in common.
This is now abstracted in the "external" Q-Reg base "class"
(ie. via initializer TECO_INIT_QREG_EXTERNAL()).
It uses vtable calls which is slightly more inefficient than per
register implementations, but avoiding redundancies is probably more
important.

FreeBSD port
* Makefiles are in .gitignore.
|
|
for debug builds
* There is cleanup that is not strictly necessary, because it only frees memory
which is freed on program termination anyway.
* However, it helps to explicitly free everything for debugging memory leaks via Valgrind.
* The new macro reduces the number of #ifdef statements.
* On NDEBUG, the code of these functions will still be eliminated.
* If functions are referenced only from the destructor, there will be no unused function
warnings, even in NDEBUG.
|
|
* it is supposed to be mainstreamed, but this did not yet happen
* even if it will eventually become part of the ports tree, I won't
have access to this repo and could not keep it up to date.
But I can keep this copy here up to date and it can serve as an
upstream source for the ports tree maintainer.
* Also, it can be used to build FreeBSD binary packages even now
without being part of the official ports tree.

|
|
|
* This is supposed to allow new users without any prior exposure to SciTECO
to pick up the basics of practical usage of SciTECO as an editor.
It almost does not elaborate on scripting-side of things.
* This requires a full Groff installation, so the document is not built by default.
|
|
* dh_testdir would sometimes cause problems on the PPA servers,
so we replaced it with an empty rule.
* We need to define the binary-arch and binary-indep targets
in order to recurse into the correct subdirectories.
I do not understand why this always worked on the Github runner
and sometimes even on the PPA servers.
Unfortunately, we cannot just call `dh binary-arch -B... -p...`
since that would call `dh_install -a` which overrides any `-p` (package),
thus trying to install the curses binaries from the Gtk build directory
and vice versa.
|
|
* This resolves must lintian warnings and errors.

packages
|
|
|
|
* Useful for packaging on platforms where we can only build from tarballs (FreeBSD)
* I don't know whether it's always safe and correct to install this file into $DATADIR/applications,
so the file is only distributed but not installed yet.
* It contains a hardcoded binary name "gsciteco". This could actually differ
depending on the concrete --program-prefix and it would be good to include the exact
installation path.
This however is not possible as long as we do not install this file.
|
|
* This is also the base of $SCITECOPATH.
* Changing it is useful for packaging where it is not possible to factor out the common
files between Curses and Gtk builds into a "sciteco-common" package.
As an alternative, you can now create disjunct sciteco-curses and sciteco-gtk packages.
* You will most likely want to use this for Gtk builds as in:
--with-interface=gtk --program-prefix=g --with-scitecodatadir=/usr/local/share/gsciteco.
|
|
* The lexer.test.* macros don't work on the unnamed buffer,
so any per-language indention settings etc. could be accidentally
applied to the unnamed buffer.
|
|
* Since Scintilla no longer automatically scrolls the caret (see 941f48da6dde691a7800290cc729aaaacd051392),
the caret wouldn't always end up in the view on startup.
* Added teco_interface_refresh() which includes SCI_SCROLLCARET and
is invoked on startup. This helps with the Curses backend.
It also reduces code redundancies.
* On Gtk, the caret cannot be easily scrolled on startup as long as no size is allocated
to the window, so we also added a size-allocate callback to the
window's event box. Sizes are less often allocated to the event box than to the
window itself for some strange reason.
|
|
* This probably did not cause any bugs.
|
|
default now
* On FreeBSD both the dlmalloc replacement and poll-thread via sysctl() work
but the poll-thread has been benchmarked to be significantly faster,
at least on my machine.
You can still ./configure --enable-malloc-replacement of course.
* Interestingly, the RSS of the process visible via htop does not decrease
after OOMs or command-line terminations - with neither of the implementations.
|
|
* it appears to behave similar to Mac OS with regard to recursions
