A first stab at refactoring In general, the goal of these changes is to be more type-specific wherever possible, reduce duplicated code, and avoid magic numbers. The biggest individual change is to use Location triples of integers wherever possible rather than three separate int variables. Another very helpful change for understanding what is going on in the code is introducing the MarkState enum for tracking the process of marking and unmarking blocks of cell. The MarkState change was motivated by the issues with Ctrl-C, and this commit, in fact, resolves #28. Because of the lack of a test harness, it is possible that a change of this scope has created some bugs as well, but teapot was running OK for me at the time of the commit. However, I don't know how good my coverage of the changed code was -- I certainly did not save or load a Lotus 1-2-3 file!

Prepare for per-cell configurable colors So far, this jst consists of initializing color in curses mode, and making the display start and end part of intializing and freeing a sheet (so that it can control allocating the palette, for example, where the data structure used depends on what kind of display it is. Next up will be to allocate and destroy the color palette, and set up the default colors for cells to use (0 for foreground, TEAPOT_WHITE for background.) The outline beyond that is to allow setting of the cell colors, then actually display those colors, and finally edit the palette.

void initialize_sheet(Sheet *sheet);
Make tpa the default file format for Teapot There turned out to be one blocking technical issue for full adpotion of tpa format, and that was the fact that the printed representation of floating values inside the tpa file might not reproduce the same double when read. This change therefore introduces the "hexact" floating point format, based on the the %La format string, which produces a hex representation with exact round trips. While working on this, it was convenient to add a new representation "compact" which is basically the shorter of decimal and scientific representations, without trailing zeros. This is now the default float format, but of course one can select decimal or scientific formats to restore prior appearance. However, full-precision compact format is now the (only) format for editing cell contents, as it is accurate and efficient. Of course you can enter floating point values in any format you like when typing in a formula. The addition of several new floating point options overloaded the menus in terminal teapot, so this change also revamps those menus slightly, including eliminating the unused MenuChoice struct, and just specifying menus with an array of strings. Closes #63.

Cell *initcellofsheet(Sheet *sheet, const Location at, bool *qnew);
Streamline internals of teapot The primary change is to add a “funcall” token, so that an entire expression can be encapsulated as a single token. This change is used to allow a cell to include simply a selection of appropriate semantic tokens. I.e., the content and iterative content are now each a single token like the value and the result value. Token vectors are used only as intermediate results in scanning and parsing. Not this means the cells are now in effect storing parse trees, so computation should be slightly faster and future extensions (like #56) should be facilitated. This commit also takes the opportunity while internals are being altered to add another token to a cell for future use for computed attributes, cf #22, and to change the internal numerical values from double and ints to long doubles and long longs. However, the change attempts to encapsulate that choice so it would be easy to change back or change to another representation. Note that these changes break savexdr(), as the internal binary format of a cell is now different. Rather than reimplement it, it is deprecated as the world does not need another binary spreadsheet format. Hence, the ascii format for teapot spreadsheets becomes the primary file format. Loading of old xdr files is still supported for backward compatibility. Closes #59. Also along the way, various other slight fixes and enhancements crept in, a partial but probably not exhaustive list of which follows: Fixes #31. Further revisions and improvements to documentation. Make the approximate comparison of floating point values scale more accurately with the size of the doubles being compared. Further extensions of absolute and relative cell addressing. Addition of (circle constant) tau function/constant. Modified string conversion to simply use internal printing routines, and to take "scientific" and "decimal" keywords. Allowed n() function to take a list of values, or just a single location defaulting to the current location. Added floor, ceil, trunc, and round functions, and allowed them to be keywords controlling the int() integer conversion function as well. Allowed substr() to drop its last argument to go to the end of the string. Provided an enum of built-in functions to preserve legacy function identifiers, allowing the large table inside func.c to be reorganized in a clearer fashion. Added additional annotation of properties of the built-in functions, including precedence. All operators are now also accessible as built-in functions. Made precedence of unary - lower than ^ to match python. Avoided inadvertently using FLTK @symbol abbreviations for formulas with "@" in them.

MarkState getmarkstate(Sheet *sheet);
Prevent phantom values when clocking, resetting, and clocking again In the end it turned out that the cause of the phantom values was short-cutting in getvalue() when the contents of a cell were empty, preventing the update of the internal cache of the value of the cell. However, tracking this down (and getting the associated memory management correct) necessitated implementing a debugging mode in which I could dump the internal states of cells and print various other stuff to standard output. It also involved understanding the meaning of various pointers in the code, in the process of which I renamed some commonly used macros, particularly the former SHEET(s,x,y,z) which was not returning a Sheet at all but rather a pointer to a Cell. So this macro is now called CELL_AT. I also replaced several very repeatedly used patterns of checking the validity of locations and pointers with macros, now defined in sheet.h. Therefore, unfortunately the (relatively small in the end) bugfix for this major issue is entangled with numerous textual changes to the code made in tracking it down. Fixes #18. Closes #19.

Token recompvalue(Sheet *sheet, const Location at);
Implement a find() macro This macro looks at each cell along some stride through the sheet, returning the location of the first cell encountered at which a given expression evaluates to true, or boolean false otherwise. To make this more useful, this change also revamps the handling of boolean values, making them much more permissive and coercing to boolean type in fewer circumstances. It adds the bool() type conversion for explicitly coercing to boolean type, and fixes a small issue with reading hex-formatted floating-point values ('p' can be used as an exponent indicator).

A first stab at refactoring In general, the goal of these changes is to be more type-specific wherever possible, reduce duplicated code, and avoid magic numbers. The biggest individual change is to use Location triples of integers wherever possible rather than three separate int variables. Another very helpful change for understanding what is going on in the code is introducing the MarkState enum for tracking the process of marking and unmarking blocks of cell. The MarkState change was motivated by the issues with Ctrl-C, and this commit, in fact, resolves #28. Because of the lack of a test harness, it is possible that a change of this scope has created some bugs as well, but teapot was running OK for me at the time of the commit. However, I don't know how good my coverage of the changed code was -- I certainly did not save or load a Lotus 1-2-3 file!

Make tpa the default file format for Teapot There turned out to be one blocking technical issue for full adpotion of tpa format, and that was the fact that the printed representation of floating values inside the tpa file might not reproduce the same double when read. This change therefore introduces the "hexact" floating point format, based on the the %La format string, which produces a hex representation with exact round trips. While working on this, it was convenient to add a new representation "compact" which is basically the shorter of decimal and scientific representations, without trailing zeros. This is now the default float format, but of course one can select decimal or scientific formats to restore prior appearance. However, full-precision compact format is now the (only) format for editing cell contents, as it is accurate and efficient. Of course you can enter floating point values in any format you like when typing in a formula. The addition of several new floating point options overloaded the menus in terminal teapot, so this change also revamps those menus slightly, including eliminating the unused MenuChoice struct, and just specifying menus with an array of strings. Closes #63.
