2015-03-16implemented automatic EOL translation supportRobin Haberkorn1-2/+0
* activated via bit 4 of the ED flag (enabled by default) * automatic EOL guessing on file loading and translation to LFs. * works with files that have inconsistent EOL sequences. * automatic translation to original EOL sequences on file saving * works with inconsistent EOL sequences in the buffer. This should usually not happen if the file was read in with automatic EOL translation enabled. * also works with the EC and EG commands * performance is OK, depending on the file being translated. When reading files with UNIX EOLs, the overhead is minimal typically-sized files. For DOS EOLs the overhead is larger but still acceptable. * Return (line feed) is now an immediate editing command. This centralizes EOL sequence insertion. Later, other features like auto-indent could be added to the editing command. * get_eol() has been moved to main.cpp (now called get_eol_seq() * Warn if file ownership could not be preserved when saving files. * IOView has been almost completely rewritten based on GIOChannels. The EOL translation code is also in IOView.
2015-03-07fixed 0EB command to display all buffers in the ringRobin Haberkorn1-1/+1
* the popup resetting was done after character insertion, so typing 0EB would clear the popup immediately * the new implementation is functionally equivalent to the old pre-reinsertion-commandline-handling, by resetting the popup based on the immediate editing command before insertion
2015-03-02introduced the ^G immediate editing command for toggling the undo/redo mode ↵Robin Haberkorn1-3/+5
(also replaces ^T) * CTRL+G toggles the behaviour of the rubout (Backspace, ^W, ^U) commands: When the so called immediate editing command modifier is enabled/active, the rubout commands will do the opposite and insert from the rubbed out command line. This command is somewhat similar to Emacs' C-g command. * The CTRL+G command also replaces the ^T immediate editing command for auto-completing filenames in any string argument. Now the TAB key can be used for that purpose after activating the ^G modifier. ^T is a classic TECO command that will be supported sooner or later by SciTECO, so it's good to have it available directly.
2015-03-01keep rubbed out command line for later re-insertion and massive Cmdline ↵Robin Haberkorn1-12/+60
cleanup/refactoring * characters rubbed out are not totally removed from the command line, but only from the *effective* command line. * The rubbed out command line is displayed after the command line cursor. On Curses it is grey and underlined. * When characters are inserted that are on the rubbed out part of the command line, the cursor simply moves forward. NOTE: There's currently no immediate editing command for reinserting the next character/word from the rubbed out command line. * Characters resulting in errors are no longer simply discarded but rubbed out, so they will stay in the rubbed out part of the command line, reminding you which character caused the error. * Improved Cmdline formatting on Curses UI: * Asterisk is printed bold * Control characters are printed in REVERSE style, similar to what Scinterm does. The controll character formatting has thus been moved from macro_echo() in cmdline.cpp to the UI implementations. * Updated the GTK+ UI (UNTESTED): I did only, the most important API adaptions. The command line still does not use any colors. * Refactored entire command line handling: * The command line is now a class (Cmdline), and most functions in cmdline.cpp have been converted to methods. * Esp. process_edit_cmd() (now Cmdline::process_edit_cmd()) has been simplified. There is no longer the possibility of a buffer overflow because of static insertion buffer sizes * Cleaned up usage of the cmdline_pos variable (now Cmdline::pc) which is really a program counter that used a different origin as macro_pc which was really confusing. * The new Cmdline class is theoretically 8-bit clean. However all of this will change again when we introduce Scintilla views for the command line. * Added 8-bit clean (null-byte aware) versions of QRegisterData::set_string() and QRegisterData::append_string()
2015-02-11updated copyright to 2015Robin Haberkorn1-1/+1
2014-11-11added all of SciTECO's declarations to the "SciTECO" namespaceRobin Haberkorn1-0/+4
normally, since SciTECO is not a library, this is not strictly necessary since every library should use proper name prefixes or namespaces for all global declarations to avoid name clashes. However * you cannot always rely on that * Scintilla does violate the practice of using prefixes or namespaces. The public APIs are OK, but it does define global functions/methods, e.g. for "Document" that clashed with SciTECO's "TECODocument" class at link-time. Scintilla can put its definitions in a namespace, but this feature cannot be easily enabled without patching Scintilla. * a "SciTECO" namespace will be necessary if "SciTECO" is ever to be turned into a library. Even if this library will have only a C-linkage API, it must ensure it doesn't clutter the global namespace. So the old "TECODocument" class was renamed back to "Document" (SciTECO::Document).
2014-02-15updated Copyright to year 2014Robin Haberkorn1-1/+1
2014-02-15removed most exception specifications: allow bad_allocs to propagateRobin Haberkorn1-1/+1
* specifications resulted in runtime errors (unexpected exception) when bad_alloc ocurred * specs should be used scarcely: only when the errors that may be thrown are all known and for documentary purposes
2013-02-22resolved enter-key handling by introducing get_eol()Robin Haberkorn1-0/+2
2013-02-16function key support (keys without printable representation) using keyboard ↵Robin Haberkorn1-0/+8
macros * if enabled, when a function key is pressed it is looked up in Q-Registers ^F... e.g. HOME key corresponds to register ^FHOME * the string if available is inserted as if it was entered by key-presses (later it may be entered as a single input token which may be removed in a single rubout) * only NCurses currently, key names directly correspond to Curses key names * on Curses if function keys are enabled ESCAPE will be inserted after a delay (because function keys are transmitted via escape sequences). A function key macro may be used to define an alternative escape character
2013-02-14option for q-reg spec state machine to allocate (insert) new q-registersRobin Haberkorn1-0/+3
* enabled for all modifying Q-Reg commands
2013-02-03first draft of commandline-editing commands ({ and } as in VideoTECO)Robin Haberkorn1-0/+1
* simplified traditional commandline editing. no need to extend cmdline string one character at a time when inserting multiple. instead there's a marker (cmdline_pos) specifying the macro length to execute in a "step" and also the anchor for generating undo tokens * implementation does not yet work in macro calls * while editing the commandline, other buffers/registers may not be edited (need push-down-list and auxiliary q-register)
2013-01-23cleaned up QRegister state interface (can pass register by reference)Robin Haberkorn1-1/+1
2013-01-23moved StateExpectQReg from parser.h to qregisters.hRobin Haberkorn1-0/+1
* parser.cpp|h should be reserved for generic and misc. stuff. the StateExpectQReg class is used almost exclusively by qregisters.cpp|h * resolves a circular header dependency issue
2013-01-23implemented special save last commandline command ("*" at beginning of ↵Robin Haberkorn1-0/+44
commandline macro) * only works as part of commandline macro, * at the beginning of other macros, it is treated like an arithmetic asterisk * variables defined in cmdline.cpp are now declared by new cmdline.h
