Age	Commit message (Collapse)	Author	Files	Lines
2012-11-21	support "\" and <n>\ commands to insert and read integers in the current ↵	Robin Haberkorn	1	-0/+64
	radix from/to the buffer * uncommon radices are allowed but reading stops on non-alphanumeric characters (and characters on allowed by the current radix)
2012-11-21	Gq command to insert Q-Register at current DOT	Robin Haberkorn	1	-0/+1

2012-11-21	<n>A command to get ASCII code from buffer (at position DOT+n)	Robin Haberkorn	1	-0/+9
	classic TECO's append-buffer command is not supported * currently, num_sign is implied for A, that is -A will retrieve the value before DOT, while "A" will retrieve after (not at) DOT
2012-11-20	fixed rubout of macro invocations: goto tables and q-registers are allocated ↵	Robin Haberkorn	1	-20/+13
	on the C++ call stack and configured to not emit undo tokens this introduces additional logic but has the huge advantage that the tables can be freed after the macro invocation. if undo tokens were emitted, the tables had to be kept in the undo stack so they can be restored during rubout. this however would be both complicated and unnecessarily inefficient since the tables would reach their initial state during rubout and be deallocated anyways. * similar (but not strictly necessary optimizations) can be performed for macro invocations * also wrapper Q-Register setting/getting -> will allow a custom "*" register getter (e.g. calculates buffer position on the fly)
2012-11-20	cleanup macro execution functions: common namespace, Execute::file() uses ↵	Robin Haberkorn	1	-28/+61
	Execute::macro()
2012-11-20	local Q-Register tables; :M command	Robin Haberkorn	1	-19/+71
	* munged files use the same local Q-Registers as commandline * :M calls macro without new set of local registers (local register names refer to the parent macro level) * only .x names accepted at the moment. for string building characters, this will like stay that way (cannot refer to extended/long names)
2012-11-20	errors when label cannot be found at end of macro invocation	Robin Haberkorn	1	-0/+5
	* on the command line the line terminating <ESC> is not accepted when a label was not found
2012-11-20	goto table cleanup	Robin Haberkorn	1	-2/+2

2012-11-20	make goto tables local to macro invocation: they are declared on the C++ ↵	Robin Haberkorn	1	-0/+6
	callstack since macro invocations result in nested macro_execute() calls otherwise a macro could set labels with program counters which are invalid in other macros/the command line
2012-11-20	support special "{" alternate escape character: is only terminated by a ↵	Robin Haberkorn	1	-7/+23
	matching balanced "}" this eases writing nested macros
2012-11-20	disable ^U string building characters (by default)	Robin Haberkorn	1	-13/+17
	some method to reenable it will be developed in the future (perhaps using a separate command, or a special modifier which reverses a string commands default handling of building character)
2012-11-20	QRegister push-down stack: [x and ]x commands	Robin Haberkorn	1	-0/+3
	* rubout is quite tricky but ensures minimal memory copying
2012-11-20	ED flags making 0-Register hook execution configurable	Robin Haberkorn	1	-0/+14
	* teco.ini updated as well
2012-11-20	Scintilla command ES accepting string parameter: if empty, pop value from ↵	Robin Haberkorn	1	-15/+25
	stack otherwise pass string
2012-11-20	cleanup strings[0] before invoking done(): can only be a preliminary solution	Robin Haberkorn	1	-7/+9

2012-11-20	first working draft of syntax highlighting support and related necessary ↵	Robin Haberkorn	1	-1/+15
	features
2012-11-18	avoid using Scintilla's SAVEPOINT mechanism altogether: fixes some ↵	Robin Haberkorn	1	-0/+5
	destructive commands * the only thing gained from (partially) using that mechanism is that no explicit calls to set the dirty-status of a buffer are necessary * however it had many disadvantages: * setting the buffer clean had to be done manually anyway (see previous commits) * when changing Q-Registers without affecting the current document, a flag had to be used to prevent setting the current document dirty * last but not least, it introduced a dependency on the order of the destructive operation and its UNDO token. * the UNDO token could trigger a SAVEPOINTLEFT notification resulting in additional rubout tokens to be pushed on the stack which screws the rubout stack. this can be avoided by clever ordering of the operations * using an explicit ring.dirtify() is therefore much better
2012-11-16	scroll caret into view after text insertion	Robin Haberkorn	1	-1/+3

2012-11-16	support different kinds of runtime errors (using C++ exceptions)	Robin Haberkorn	1	-57/+65
	* also added some additional range checks (e.g. X command)
2012-11-16	support EF and EX arguments. FALSE (>= 0) means to refuse closing/exiting if ↵	Robin Haberkorn	1	-0/+10
	the current file / any file is dirty (modified) -EF and -EX may be used to enforce a close/quit without saving
2012-11-15	minor change to avoid compiler warning	Robin Haberkorn	1	-1/+1

2012-11-15	added Interface class to ease porting SciTECO to other platforms (toolkits)	Robin Haberkorn	1	-57/+57
	* will support Scintilla with Scinterm/NCurses * changes are in such a way that the generated machine code should have almost no overhead compared to the previous implementation (at least when compiled with optimizations)
2012-11-14	minor comment fix	Robin Haberkorn	1	-1/+1

2012-11-14	error checking and colon modifier support for lots of commands	Robin Haberkorn	1	-42/+143

2012-11-14	simplified move_lines() a bit	Robin Haberkorn	1	-2/+1

2012-11-13	EF command to close a buffer	Robin Haberkorn	1	-0/+7
	can be rubbed out!!! this works because when a buffer is closed, it is not deallocated but transferred to the undo token object which then (if run) reinserts it into the ring list. if the undo token is destroyed before it is run (eg. <ESC><ESC> pressed), the buffer will finally be deallocated.
2012-11-13	<n>W, <n>V, <n>Y commands	Robin Haberkorn	1	-0/+56
	based on Scintilla editor key commands, so they will automatically adopt to Scintilla setting changes
2012-11-13	minor simplification	Robin Haberkorn	1	-1/+1

2012-11-13	added EW...$ command	Robin Haberkorn	1	-1/+2
	* EW$ saves file with its current filename * EW<filename>$ saves file with under the specified filename (Save As) * files are stored with absolute paths in the ring

2012-11-13	Search command: use clever circular stack for the last (-n) matches for n < ↵	Robin Haberkorn	1	-11/+9
	0 in <n>S...$ * the requested number of occurrences is usually much smaller than the number of bytes in the document * still, (n) can be arbitrarily large, so allocate that stack
2012-11-13	when doing a reverse search, allocate array of matches (since it can ↵	Robin Haberkorn	1	-1/+3
	currently get very large)
2012-11-13	<x[,y]>S...$ command (only regexp searching at the moment)	Robin Haberkorn	1	-3/+130
