2015-06-29MicroStateMachine::input() returns whether a result was set nowRobin Haberkorn1-2/+2
* this means that QRegSpecMachine::input() no longer has to return a dummy QRegister in parse-only mode. This saves an unnecessary QRegister table lookup and speeds up parsing. * QRegSpecMachine can now be easily extended to behave differently when returning a Q-Register, e.g. simply returning NULL if a register does not exist, or returning a register by prefix. This is important for some planned commands. * StateExpectQReg::got_register() now gets a QRegister *. It can theoretically be NULL - still we don't have to check for NULL in most cases since NULL is only passed in parse-only mode.
2015-06-12support UNIX-shell-like tilde-expansions in file names and directoriesRobin Haberkorn1-1/+7
* expands to the value of $HOME (the env variable instead of the register which currently makes a slight difference). * supported for tab-completions * supported for all file-name accepting commands. The expansion is done centrally in StateExpectFile::done(). A new virtual method StateExpectFile::got_file() has been introduced to pass the expanded/processed file name to command implementations. * sciteco(7) has been updated: There is now a separate section on file name arguments and file name handling in SciTECO. This information is important but has been scattered across the document previously. * optimized is_glob_pattern() in glob.h
2015-06-02added <FG> command and special Q-Register "$" to set and get the current ↵Robin Haberkorn1-0/+46
working directory * FG stands for "Folder Go" * FG behaves similar to a Unix shell `cd`. Without arguments, it changes to the $HOME directory. * The $HOME directory was previously only used by $SCITECOCONFIG on Unix. Now it is documented on its own, since the HOME directory should also be configurable on Windows - e.g. to adapt SciTECO to a MinGW or Cygwin installation. HOME is initialized just like the other environment variables. This also means that now, the $HOME Q-Register is always defined and can be used by platform-agnostic macros. * FG uses a new kind of tab-completion: for directories only. It would be annoying to complete the FG command after every directory, so this tab-completion does not close the command automatically. Theoretically, it would be possible to close the command after completing a directory with no subdirectories, but this is not supported currently. * Filename arguments are no longer completed with " " if {} escaping is in place as this brings no benefit. Instead no completion character is inserted for this escape mode. * "$" was mapped to the current directory to support an elegant way to insert/get the current directory. Also this allows the idiom "[$ FG...new_dir...$ ]$" for changing the current directory temporarily. * The Q-Register stack was extended to support restoring the string part of special Q-Registers (that overwrite the default functionality) when using the "[$" and "]$" commands. * fixed minor typos (american spelling)
2015-03-01keep rubbed out command line for later re-insertion and massive Cmdline ↵Robin Haberkorn1-3/+2
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()
2015-02-14updated Scintilla submodule: fixed tab stop calculation on CursesRobin Haberkorn1-1/+1
* also did some whitespace cleanup in SciTECO now that tabs are displayed properly
2015-02-11updated copyright to 2015Robin Haberkorn1-1/+1
2015-02-11implemented support for different indention stylesRobin Haberkorn1-0/+12
* 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
2014-11-22added EI as non-string-building variant of IRobin Haberkorn1-1/+6
this is analoguous to EU as the string-build equivalent of ^U.
2014-11-11refactored SciTECO runtime errors: moved from parser.cpp to error.cppRobin Haberkorn1-189/+2
* the GError expection has been renamed to GlibError, to avoid nameclashes when working from the SciTECO namespace
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).
2014-11-09revised U command: fail if no argument is providedRobin Haberkorn1-0/+8
* there is no reasonable default value for U * omitting the parameter for U might be a frequent programming error * U can be colon-modified now, in which case it may be used * to check for the presence of arguments in macros
2014-02-15updated Copyright to year 2014Robin Haberkorn1-1/+1
2014-02-15added State::StdError class for constructing errors from std::exception objectsRobin Haberkorn1-0/+11
2014-02-15use GLib's GError information to yield errorsRobin Haberkorn1-0/+6
* results in better error messages, e.g. when opening files * the case that a file to be opened (EB) exists but is not readably is handled for the first time
2014-02-15fixed Execute::macro() and Execute::file() exceptionsRobin Haberkorn1-4/+40
* might throw other exceptions that must be associated with the parent macro level's (stack frame) * add position information to "label not found" errors * Error copy constructors
2014-02-15removed most exception specifications: allow bad_allocs to propagateRobin Haberkorn1-20/+20
* 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
2014-02-15String::get_coord() calculates line and column of a string positionRobin Haberkorn1-11/+10
* use to get line and column into a stack frame
2014-02-15added support for TECO stack tracingRobin Haberkorn1-3/+80
* when an error is thrown, stack frames are collected on clean up, up to the toplevel macro * the toplevel macro decides how to display the error * now errors in interactive and batch mode are displayed differently * in batch mode, a backtrace is displayed as a sequence of messages * Execute::file() forwards errors correctly * the correct error in the file is displayed in interactive mode * necessary to build the stack trace
2014-02-15added EMCurses/Emscripten supportRobin Haberkorn1-1/+7
by building with Emscripten support, SciTECO may be embedded into web pages. * sciteco.html is not a piece of documentation but a sample SciTECO embedding
2013-03-19avoid delete-non-virtual-dtor warning on g++ 4.7Robin Haberkorn1-0/+1
* the warning itself makes sense but in the cases reportet they were irrelevant

2013-03-16common parent state for all file-name-expecting commands: fixes EM ↵Robin Haberkorn1-0/+12
tab-completions * StateExpectFile adds no functionality (currently), but is useful for checking state types
2013-02-22use typedef for SciTECO integers and make it configurable at configure timeRobin Haberkorn1-5/+5
* storage size should always be 64 (gint64) to aid macro portability * however, for performance reasons users compiling from source might explicitly compile with 32 bit integers
2013-02-16implemented command to query ASCII code of character (^^x)Robin Haberkorn1-0/+9
2013-02-14hide some implementation details in MicroStateMachinesRobin Haberkorn1-5/+12
2013-02-14use Q-Register micro state machine when parsing Q-Reg spec in ↵Robin Haberkorn1-7/+8
string-building commands * allows referring to long Q-Register names in string arguments * currently, long names specified this way use their own string building char parsing (I'm unsure whether this makes any sense)
2013-02-14rewritten string building state machine using a common MicroStateMachine ↵Robin Haberkorn1-25/+51
base class * uses label pointers instead of state-enum and switch case (both faster and shorter to write) * common interface for all micro state machines: makes them reusable
2013-02-11States::is_string() to check whether current state is a string-stateRobin Haberkorn1-0/+6
2013-02-08reverse Execute::step() change: no need to pass parameters by referenceRobin Haberkorn1-1/+1
cmdline and cmdline_pos is no longer modified by code executed by step() instead it is modified at the outermost macro level (commandline macro level)
2013-02-08use special Q-Register $ (<ESC>) to hold the replacement commandlineRobin Haberkorn1-1/+1
* allows us to switch between buffers/registers when editing the commandline
2013-02-08delegate commandline replacements ("}") to the cmdline macro levelRobin Haberkorn1-6/+17
allows commandline editing scripted by macros
2013-02-03first draft of commandline-editing commands ({ and } as in VideoTECO)Robin Haberkorn1-1/+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)
2013-01-23moved StateExpectQReg from parser.h to qregisters.hRobin Haberkorn1-22/+0
* 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
