this looks better in Unicode terminals
|
|
* for historic reasons, the backspace key can be transmitted as
^H by the terminal. Some terminal emulators might do that - these
are fixed by this commit.
* Use CTL_KEY('H') instead of standard C '\b' as the former is less
ambiguous given the confusion around the backspace character.

removal of ^T
|
|
* the ^I command was altered to insert indention characters
rather than plain tabs always.
* The <TAB> immediate editing command was added for all
insertion arguments (I, ^I but also FR and FS)
* documentation was extended for a discussion of indention

Windows
* this is actually UNTESTED on Windows

optimized screen refreshing/redrawing
* pressing e.g. TAB when the popup is showing a list of auto-completions
will show the next page, eventually beginning at the first one again.
* do not redraw curses windows in the UI methods directly. this resulted
in flickering during command-line editing macros and ordinary macro calls
because the physical screen was updated immediately.
Instead, window refreshing and updated is done centrally in
event_loop_iter() only after a key has been processed.
Also we use wnoutrefresh() and doupdate() to send as little to the
terminal (emulator) as possible.

* added platform-dependant file_is_visible() function

this is more consistent with SciTECO's idea of abstract registers
and allows the currend buffer to be saved on the Q-Register stack.
This allows the idiom: [* ! ...change current buffer... ! ]*

also changed precedence of + operator (higher than minus).
the effects of this should be minimal
|
|
|

this breaks many existing scripts, and means you may have to rebuild SciTECO
with ./configure --enable-bootstrap
The syntax of SciTECO might change in backwards-incompatible until
version 1.0 is released.

|
|
* new Expressions::format()
* may be used format numbers as part of arrays (Q-Register names)

it is customary for Troff preprocessors to interpret special preprocessor requests
instead of special comments

sciteco(7) manual
* images are generated by grohtml. they are not listed in the Automake rules but instead all
sciteco.*.png images are installed and cleaned
|
|
|
|
* also updated sciteco(7): add SEE ALSO and AUTHORS
|
|
* the language reference is a manually written man-page template
* containing special references for generated documentation (\#$...)
* SciTECO script generate-docs.tes extracts TECO comments (/*$ ... */)
from all source files and transforms them to Troff requests that are
inserted into the document template.
* TECO doc comments are a rather sophisticated markup:
* first part until empty line is called header: simplified command syntax descriptions
* the rest is called body: <identifier> is automatically underlined,
empty lines generate new paragraphs, lines beginning with "-" or numbers
denote an indented unordered or numbered list item.
* regular Troff requests/macros can be used for more sophisticated markup
* since Autoconf substitutions are performed on the generated man-page,
@VARIABLEs@ may be used in doc comments as well
