Known Bugs:
* ??? Dot is not always restored properly (e.g. after closing file)
need test case!!!
* Null-byte in strings not always handled transparently
* saving another user's file will only preserve the user when run as root
(WON'T FIX!?)
* Scintilla/Scinterm: sometimes <TAB> indents too much (see e.g. state declarations)
* crashes on large files: S^EM^X$ (regexp: .*)
* m,nX crashes if m > n
Features:
* some missing useful VideoTECO/TECO-11 commands:
* EF with buffer id
* ER command: read file into current buffer at dot
* $$, ^C: return from macro
* nEW to save a buffer by id
* use CRTP for RBTrees
* "~" expansion in file names
* properly support Unicode encodings and the character-based model
* link against libncursesw if possible
* translate documents to Unicode strings
* a position refers to a character/codepoint
* Progress indication in commandline cursor
* undo-tokens per char limit (additional infinite loop safety)
* Command to free Q-Register (remove from table)
* autocompletion of long Q-Reg names
* Q-Register aliasing/linking
* TECO syntax highlighting
* multiline commandline
* perhaps use Scintilla view as mini buffer
* improve GTK interface
* ??? optional modified-detection based on hash sums ???
* backup files, or even better Journal files:
could write a Macro file for each modified file containing
only basic commands (no loops etc.). it is removed when the file is
saved. in case of an abnormal program termination the
journal file can be replayed.
* Add special Q-Register for dot:
Would simplify inserting dot with string building and saving/restoring
dot on the QReg stack
* automatic EOL detection of buffers; easy EOL setting
* command to change the current working directory. This will
influence tab-completion and relative file names.
Optimizations:
* prevent command-line flickering when using function key macros.
* check if Scinterm refreshing is optimal
* refactor search commands (create proper base class)
* refactor match-char state machine using MicroStateMachine class
* simplify parser (static jump tables are unnecessary!)
* search and other commands can be significantly optimized:
in batch mode, or in loops/macros there is no need to rematch every character!
-> immediate vs. non-immediate command execution
* can be handled automatically in StateExpectString
* batch mode can be optimized by preventing unnecessary allocations/deallocations
for UNDO token creation. Check for undo.enabled in constructors like
undo.push_msg|var() where the undo token destruction does not have any
significant side effects.
* use "friend" functions for C-linkage callbacks that must access a class'
member instead of making that member public.
Alternatively, I can use public context structures that are private
attributes.
* when setting/getting Q-Reg string, use special dummy Scintilla view
Documentation:
* Code docs (Doxygen)
* clean up/fix generate-docs.tes
