2016-08-19Integrated clipboard supportRobin Haberkorn2-12/+360
* mapped to different registers beginning with "~" * on supported platforms accessing the clipboard is as easy as X~ or G~. Naturally this also allows clipboards to be pasted in string arguments/insertions (^EQ~). * Currently, Gtk+, PDCurses and ncurses/XTerm are supported. For XTerm clipboard support, users must set 0,256ED to enable it since we cannot check for XTerm window ops programmatically (at least without libX11). * When clipboard regs exist, the clipboard can also be deemed functional. This allows macros to fall back to xclip(1) if necessary. * EOL handling has been moved into a new file eol.c and eol.h. EOL translation no longer depends on GIOChannels but can be memory-backed as well.
2016-02-10avoid unnecessary undo token allocations in batch mode: greatly speeds up ↵Robin Haberkorn1-1/+1
batch mode * by using variadic templates, UndoStack::push() is now responsible for allocating undo tokens. This is avoided in batch mode. * The old UndoStack::push(UndoToken *) method has been made private to avoid confusion around UndoStack's API. The old UndoStack::push() no longer needs to handle !undo.enabled, but at least asserts on it. * C++11 support is now required, so variadic templates can be used. This could have also been done using manual undo.enabled checks; or using multiple versions of the template with different numbers of template arguments. The latter could be done if we one day have to support a non-C++11 compiler. However since we're depending on GCC 4.4, variadic template use should be OK. Clang supports it since v2.9. * Sometimes, undo token pushing passed ownership of some memory to the undo token. The old behaviour was relied on to reclaim the memory even in batch mode -- the undo token was always deleted. To avoid leaks or repeated manual undo.enabled checking, another method UndoStack::push_own() had to be introduced that makes sure that an undo token is always created. In batch mode (!undo.enabled), this will however create the object on the stack which is much cheaper than using `new`. * Having to know which kind of undo token is to be pushed (taking ownership or not) is inconvenient. It may be better to add static methods to the UndoToken classes that can take care of reclaiming memory. * Benchmarking certain SciTECO scripts have shown 50% (!!!) speed increases at the highest possible optimization level (-O3 -mtune=native -march=native).
2016-01-31CursesInfoPopup: separated the Curses popup widget from the rest of the UI codeRobin Haberkorn7-356/+514
* this has been prepared a long time ago * the popup widget does not in any way depend on the InterfaceCurses class and could be used elsewhere. * common and generic Curses drawing functions required by both the Curses UI and the CursesInfoPopup widget have been factored out into curses-utils.cpp (namespace Curses) * this improved the UI-logic separation and helped in making interface-curses.cpp smaller
2016-01-31interfaces have their own automake subdirectories and convenience libraries nowRobin Haberkorn3-0/+1789
* use libtool convenience libraries as much as possible (for all static libraries except Scintilla) * improves separation of language and user interface implementations (e.g. the Gtk widgets are not interesting for the rest of SciTECO) * the Curses popup widget can now be factored out of interface-curses.cpp * some common CPPFLAGS are now defined by ./configure via AM_CPPFLAGS, so they don't have to be repeated in each submodule. * fixed building the Curses UI: GTK_FLOW_BOX_FALLBACK conditional must always be defined.
