* After detecting +line[,column] constructs, the next argument is not parsed as a potential
filename:line[:column] construct.
* This code turned out to be tricky to get right, so I added a test case.
Standard library modules can well be checked in the test suite since
we have $SCITECOPATH pointing to the source tree's lib/ directory.
* Make sure that relevant variables from atlocal.in are really exported into the
process environment.
This was also broken for the Glib debug options.

* Set up the folding margin in the currently empty margin column
after the line number.
On Gtk, this meant resetting all the marker symbols and their
foreground/background colors as well as the margin's colors themselves.
This looks like a bug. It's not necessary on Scinterm, which apparently
uses the default/linenumber styles by default.
Perhaps we should try upgrading Scintilla?
* The folding state is considered not to be directly controlled by the
language (just like the scroll position and zoom level). That's why
we can directly control it by clicking on the margin column.
* F1 can be used to toggle all folds globally.
* The only support within the C core necessary for folding is to make
sure that the current line is unfolded after every keypress.
* We might add custom folding commands to the language later on
(e.g. F+, F-). In this case, the key macros will have to be changed
of course.

customized (refs #34)
* In the grosciteco-generated .woman.tec files, the fonts were only
set on the monospaced styles if lexer.font was set since it was
undefined by default.
We'd need a lare IF-ELSE statement to handle that in womanpages
since woman.tes changes the default font to a variable-width font.
Just leaving the default font, therefore won't work.
* We now always initialize lexer.font in lexer.tes.
You no longer have to check for its existance.
* Consequently, you can no longer set lexer.font *before* munging
lexer.tes because it will be overwritten.
At least not without additional checks.
Such a design is not suggested by fallback.teco_ini, though.
* Fixes monospaced sections in the tutorial and other womanpages on Gtk.

variable-width font is configurable via lexer.woman.font (refs #34)
* grosciteco was just hardcoding "Monospace", regardless of what was configured via lexer.font in ~/.teco_ini
* The variable-width font used for ordinary "womanpage" body texts was hardcoded to "Serif".
It is now configurable via the lexer.woman.font register.
* There is a difference, though:
lexer.font has no default value and must therefore be checked everywhere.
This is so you can set it even before munging lexer.tes.
lexer.woman.font however has a default (Serif), so it can only be overridden after
munging lexer.tes.
Perhaps it would be easier and more consistent to have a default for lexer.font as well.

file.patterns
The former is more basic and usually references file.patterns.
This helped for instance with processing SciTE's css.properties.
|
|
Especially useful since Gtk users are supposed to edit ~/.teco_css.
|
|
* The default womanpage font is the abstract "Serif" now, so that should be
more portable. "Times" wasn't found on Windows.
* Win32 distributions include a custom .teco_css now, which
removes the small-caps font attribute from the type label.
The default Gtk theme on Windows references the "Segoe UI" font
and it doesn't have a small-caps variant.
In fact no default Windows font appears to have one.
* We could add a custom .teco_ini to win32 distributions as well,
but there is currently no need for it.
* Do not distribute the /win32 files. They are used only for building
Win32/64 packages. There is no point in distributing them in the tarball if
the /debian and /freebsd directories aren't distributed as well.

update the horizontal position (4EJ)
|
|
* Unfortunately, the Lexilla lexer does not recognize PostgreSQL multiline
strings between $$...$$.
* All of the other SQL variants, that Scite supports, are skipped for the time
being. They'd probably have to be separate SciTECO lexer configs anyway.
|
|
* The old heuristics - scroll if dot changes after key press -
turned out to be too simplistic.
They broke the clang-format macro (M#cf), which left the view at the
top of the document since the entire document is temporarily erased.
Other simplified examples of this bug would be:
@^Um{[: HECcat$ ]:} Mm
Or even: @^Um{[: H@X.aG.a ]:} Mm
* Actually, the heuristics could be tricked even without deleting any
significant amount of text from the buffer.
The following test case replaces the previous character with a linefeed
in a single key press:
@^Um{-DI^J$} Mm
If executed on the last visible line, dot wouldn't be scrolled into the view
since it did not change.
* At the same time, we'd like to keep the existing mouse scroll behavior from
fnkeys.tes, which is allowed to scroll dot outside of the visible area.
Therefore, dot is scrolled into view always, except after mouse events.
You may have to call SCI_SCROLLCARET manually in the ^KMOUSE macro,
which is arguably not always straight forward.
* Some macros like M#cf may still leave the vertical scrolling position
in unexpected positions. This could either be fixed by eradicating all
remaining automatic scrolling from Scintilla or by explicitly restoring
the vertical position from the macro (FIXME).
* This was broken since the introduction of mouse support,
so it wasn't in v2.3.0.
|
|
There are still some glitches with non-mainstream assemblers like A86, though.
|
|
--without-lexilla
They don't require Lexilla, so it makes no sense not to exclude them.
|
|
* This is rendered with ms, so we now need the entire groff on Debian.
This is not a big deal as it just adds a few kilobytes of build-time dependencies.
Most platforms do not allow installation of some "groff-base" package anyway
and always draw in the entire package.
* sciteco.tmac has been extended to disable page breaks on ms.
* The tutorial is installed like any other woman page and can be invoked
interactively with ?tutorial$.
* It is optimized to be still usable on a plain 80x24 terminal.
|
|
The trailing digits where cut off the filename.
E.g. when trying `sciteco test.f77:100`, we would open test.f on line 100 instead.

lParam as null-terminated strings
* Being able to embed null bytes into the lParam string is
practically useless - there aren't any messages where this is useful
and where there are no native SciTECO counterparts - so this case is now catched
and the null-byte separates wParam from lParam.
* wParam can be the empty string, but it is not supported to pass wParam as a
string and lParam as the empty string.
If the second string argument ends in ^@, lParam is popped from the stack instead.
* This is a temporary workaround until we can properly parse the Scintilla.iface and
generate more elegant per-message wrappers.
* It in particular unlocks the SCI_SETREPRESENTATION and SCI_SETPROPERTY messages.
The former allows us to write a special hex-editor macro which sets hexadecimal
character representations, while the latter allows you to set lexer properties.
* The C-based lexers ("cpp" in Lexilla) can now take preprocessor definitions into account.
This is disabled by default, unless you set lexer.c.defines before opening a file.
You can also set it interactively and re-set the lexer. For instance:
^U[lexer.c.defines]NDEBUG$ M[lexer.set.c]

the beginning of words now
* All commands and their documentations were inconsistent.
* ^W rubbed out to the beginning of words.
* Shift+Right (fnkeys.tes) moved to the beginning of the next word if
invoked at the beginning of a word and to the end of the next word otherwise.
* <W> (and <V> and <Y> by extension) moved to the end of the next word.
* The cheat sheet would claim that <W> moves to the beginning of the next word.
* Video TECO's <W> command would differ again from everything else.
With positive arguments, it moved to the beginning of words, while
with negative it moved to end of words.
I decided not to copy this behavior.
* It has been decided to adopt a consistent beginning-of-words policy.
-W therefore differs from Video TECO in moving to the beginning of the
current or previous word.
* teco_find_words() is now based on parsing the document pointer, instead
of relying on SCI_WORDENDPOSITION, since the latter cannot actually be
used to skip strictly non-word characters.
This requires a constant amount of Scintilla messages but will require fewer
messages only when moving for more than 3 words.
* The semantics of <W> are therefore now consistent with Vim and Emacs as well.
* Shift+Right/Left is still based on SCI_WORDENDPOSITION, so it's behavior
differs slightly from <W> for instance at the end of lines, as it will
stop at linebreaks.
* Unfortunately, these changes will break lots of macros, among others
the M#rf, M#sp and git.blame macros ("Useful macros" from the wiki).
|
|
* You practically never want to indent in SciTECO code with hard tabs, as the hard tab is
an insertion command.
* 2-char soft tabs are the convention in SciTECO's included macros.
* Fixes the M#it macro among other things.
* If you do want to insert an insertion-with-tab command (ASCII 9), you almost always will
want to type it ^I instead.
Real ASCII 9s should consequently be highlighted, ie. there should be a character representation.
Unfortunately, character representations are currently set in C code and cannot be changed via <ES>.
|
|
These are all more or less plain text formats.
|
|
* Highlights both 1st level and 2nd level quotes and signatures.
* This also sets the edge to 78 columns, as is recommended for email and
enables word wrapping.
The edge mode is not set, since it kind of looks ugly in Scinterm.
* Helps when using SciTECO as the email editor for instance in the
Aerc mail client.
* Unfortunately, we cannot set up Scintilla to automatically break words
after 78 columns (or perhaps that's a good thing).
You can use the M#rf reformat-paragraph macro to reflow paragraphs
before sending the mail.
This will take the edge column into account even if no edge mode is set.
|
|
* Using the same values as on Curses/scinterm resulted in too dark colors with
terminal.tes. (solarized.tes actually defines all colors with its own RGB values,
so the look has always been consistent between Curses and GTK.)
This is because the values like 0xFF0000 for red are actually just placeholders in Scinterm,
in turn translated internally to Curses colors, which are interpreted by terminal emulators
with possibly various different color palettes.
* We therefore now use the exact RGB values as will be used by common terminal emulators
like xterm and st.
It does not guarantee that the colors will always match between Curses and GTK,
but at least the GTK colors are now a bit brighter.
|
|
* You need to set 0,64ED to enable mouse processing in Curses.
It is always enabled in Gtk as it should never make the experience worse.
sample.teco_ini enables mouse support, since this should be the new default.
`sciteco --no-profile` won't have it enabled, though.
* On curses, it requires the ncurses mouse protocol version 2, which will
also be supported by PDCurses.
* Similar to the Curses API, a special key macro ^KMOUSE is inserted if any of the supported
mouse events has been detected.
* You can then use -EJ to get the type of mouse event, which can be used
with a computed goto in the command-line editing macro.
Alternatively, this could have been solved with separate ^KMOUSE:PRESSED,
^KMOUSE:RELEASED etc. pseudo-key macros.
* The default ^KMOUSE implementation in fnkeys.tes supports the following:
* Left click: Edit command line to jump to position.
* Ctrl+left click: Jump to beginning of line.
* Right click: Insert position or position range (when dragging).
* Double right click: insert range for word under cursor
* Ctrl+right click: Insert beginning of line
* Scroll wheel: scrolls (faster with shift)
* Ctrl+scroll wheel: zoom (GTK-only)
* Currently, there is no visual feedback when "selecting" ranges
via right-click+drag.
This would be tricky to do and most terminal emulators do not appear
to support continuous mouse updates.

* This is done via the new opener.tes in the standard library.
* Some programs that use $EDITOR expect the +line syntax to work.
* You can copy filename:line:column directly from GCC error messages
and filename:line from grep output.
* Since there may be safe file names beginning with "+" or containing colons,
there needs to be a way to turn this off, especially for scripts that don't
know anything about the filenames to open.
This is done with "--".
Unfortunately, the first "--", that stops parameter processing,
is always removed from the command line and not passed down into TECO land.
This is not a problem for stand-alone scripts,
since the script filename is already stopping option processing, so "--"
would get passed down.
But when calling the profile via `sciteco -- ...`, you could prevent leading
minus signs to cause problems but since the `--` is removed, opener.tes cannot
use it as a hint.
Therefore, we introduced `-S` as a new alternative to `--`, that's always passed
down as `--` (i.e. it is equivalent to "-- --").
In other words, `sciteco -S *` will always open exactly the specified files
without any danger of misinterpreting certain file names.
Should we ever switch to a custom option parsing algorithm, we might preserve
"--" (unless after --mung) and thus get rid of "-S".
* This advanced behavior can be tweaked by the user relatively easily.
In the easiest case, we could replace M[opener] with
<:L;R 0X.f [* @EB/^EN.f/ ]* L>
in ~/.teco_ini to completely disable the special syntax.
|
|
* This goes into session.vcs as well.
* `fossil info` does not allow printing only the local-root property, so we have to do
some parsing afterwards.
|
|
* In fact, since SVN has --no-newline, this is even simpler than on Git and Mercurial.
* This requires at least Subversion v1.9 (2015, so should be safe).
|
|
* The previous convention of !* ... *! are now true block comments,
i.e. they are parsed faster, don't spam the goto table and allow
embedding of exclamation marks - only "*!" terminates the comment.
* It is therefore now forbidden to have goto labels beginning with "*".
* Also support "!!" to introduce EOL comments (like C++'s //).
This disallows empty labels, but they weren't useful anyway.
This is the shortest way to begin a comment.
* All comment labels have been converted to true comments, to ensure
that syntax highlighting works correctly.
EOL comments are used for single line commented-out code, since it's
easiest to uncomment - you don't have to jump to the line end.
This is a pure convention / coding style.
Other people might do it differently.
* It's of course still possible to abuse goto labels as comments
as TECO did for ages.
* In lexing / syntax highlighting, labels and comments are highlighted differently.
* When syntax highlighting, a single "!" will first be highlighted as a label
since it's not yet unambiguous. Once you type the second character (* or !),
the first character is retroactively styled as a comment as well.

It's a bit easier on the eyes.

"identifier" to enable lexing in the container
* SCI_SETILEXER(NULL) is not a reliable way to do that since
that's the default for all views.
* This was breaking the git.tes lexer for instance and was unnecessarily
driving teco_lexer_style() on plain-text documents.
* Since we currently do not implement the ILexer5 C++ interface
and teco_view_t is just a pointer alias, we are abusing the view's "identifier" instead.
This is probably sufficient, as long as there is only one lexer "in the container".
Otherwise, there should perhaps be a single C++ class that does nothing but
wrapping a callback into an ILexer5 object with a C ABI.
|
|
* this works by embedding the SciTECO parser and driving it always (exclusively)
in parse-only mode.
* A new teco_state_t::style determines the Scintilla style for any character
accepted in the given state.
* Therefore, the SciTECO lexer is always 100% exact and corresponds to the current
SciTECO grammer - it does not have to be maintained separately.
There are a few exceptions and tweaks, though.
* The contents of curly-brace escapes (`@^Uq{...}`) are rendered as ordinary
code using a separate parser instance.
This can be disabled with the lexer.sciteco.macrodef property.
Unfortunately, SciTECO does not currently allow setting lexer properties (FIXME).
* Labels and comments are currently styled the same.
This could change in the future once we introduce real comments.
* Lexers are usually implemented in C++, but I did not want to draw in C++.
Especially not since we'd have to include parser.h and other SciTECO headers,
that really do not want to keep C++-compatible.
Instead, the lexer is implemented "in the container".
@ES/SCI_SETILEXER/sciteco/ is internally translated to SCI_SETILEXER(NULL)
and we get Scintilla notifications when styling the view becomes necessary.
This is then centrally forwarded to the teco_lexer_style() which
uses the ordinary teco_view_ssm() API for styling.
* Once the command line becomes a Scintilla view even on Curses,
we can enabled syntax highlighting of the command line macro.
|
|
* As known from DEC TECO, but extended to convert absolute positions to line numbers as well.
:^Q returns the current line.
* Especially useful in macros that accept line arguments,
as it is much shorter than something like
^E@ES/LINEFROMPOSITION//+Q.l@ES/POSITIONFROMLINE//:^E-.
* On the other hand, the fact that ^Q checks the line range means we cannot
easily replace lexer.checkheader with something like
[:J 0,^Q::S...$ ]:
Using SCI_POSITIONFROMLINE still has the advantage that it returns `Z` for out-of-bounds ranges
which would be cumbersome to write with the current ^Q.
* Perhaps there should be a separate command for converting between absolute lines and positions
and :^Q should be repurposed to return a failure boolean for out-of-range values?
* fnkeys.tes could be simplified.
|
|
::FS as well)
* The colon modifier can now occur 2 times.
Specifying `@` more than once or `:` more than twice is an error now.
* Commands do not check for excess colon modifiers - almost every command would have
to check it. Instead, a double colon will simply behave like a single colon on most
commands.
* All search commands inherit the anchored semantics, but it's not very useful in some combinations
like -::S, ::N or ::FK.
That's why the `::` variants are not documented everywhere.
* The lexer.checkheader macro could be simplified and should also be faster now,
speeding up startup.
Eventually this macro can be made superfluous, e.g. by using 1:FB or 0,1^Q::S.
|
|
|
|
* 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.
|
|
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.
|
|
The macro prefix was changed from ^F to ^K.
|
|
* Curses: "icons" have also been added
|
|
This previously highlighted little more than embedded Javascripts.
|
|
* ALL keypresses (the UTF-8 sequences resulting from key presses) can now be remapped.
* This is especially useful with Unicode support, as you might want to alias
international characters to their corresponding latin form in the start state,
so you don't have to change keyboard layouts so often.
This is done automatically in Gtk, where we have hardware key press information,
but has to be done with key macros in Curses.
There is a new key mask 4 (bit 3) for that purpose now.
* Also, you might want to define non-ANSI letters to perform special functions in
the start state where it won't be accepted by the parser anyway.
Suppose you have a macro M→, you could define
@^U[^K→]{m→} 1^_U[^K→]
This effectively "extends" the parser and allow you to call macro "→" by a single
key press. See also #5.
* The register prefix has been changed from ^F (for function) to ^K (for key).
This is the only thing you have to change in order to migrate existing
function key macros.
* Key macros are enabled by default. There is no longer any way to disable
function key handling in curses, as I never found any reason or need to disable it.
Theoretically, the default ESCDELAY could turn out to be too small and function
keys don't get through. I doubt that's possible unless on extremely slow serial lines.
Even then, you'd have to increase ESCDELAY and instead of disabling function keys
simply define an escape surrogate.
* The ED flag has been removed and its place is reserved for a future mouse support flag
(which does make sense to disable in curses sometimes).
fnkeys.tes is consequently also enabled by default in sample.teco_ini.
* Key macros are handled as an unit. If one character results in an error,
the entire string is rubbed out.
This fixes the "CLOSE" key on Gtk.
It also makes sure that the original error message is preserved and not overwritten
by some subsequent syntax error.
It was never useful that we kept inserting characters after the first error.
|
|
It's not a real Lexilla lexer, but simply styles the document
once in lexer.set.git in order to highlight comment lines.
|
|
* ^Uq however always sets an UTF8 register as the source
is supposed to be a SciTECO macro which is always UTF-8.
* :^Uq preserves the register's encoding
* teco_doc_set_string() now also sets the encoding
* instead of trying to restore the encoding in teco_doc_undo_set_string(),
we now swap out the document in a teco_doc_t and pass it to an undo token.
* The get_codepage() Q-Reg method has been removed as the same
can now be done with teco_doc_get_string() and the get_string() method.
|
|
|
|
between glyph and byte offsets (refs #5)
* ^E is heavily overloaded and can also be used to check whether a given index is valid
(as it is the same that most movement commands to internally).
Besides that, it is mainly useful for interfacing with Scintilla messages.
* EE takes a code page or 0 for ANSI/ASCII.
Currently all documents and new registers are UTF-8.
There will have to be some kind of codepage inheritance and a single-byte-only mode.
|
|
* 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).
|
|
* 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)`.
|
|
* 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.
|
|
|
|
* This does not make sense for most SciTECO builds, but only when you
want to optimize for size as the lexers take up 50% of the compressed binary
size.
Without Lexilla, it should be possible get it compiled in about 500kb.
* It can be useful for instance when building for embedded distributions.
* When Lexilla is disabled, symbols-scilexer.c is also not generated
(we assume that the Lexilla sources are not available and it also doesn't serve any purpose).
* Consequently, most of the lexer configuration scripts are also not installed
under --without-lexilla.
