Dekel:
|
||||
|
||||
Macros:
|
||||
|
||||
// - When changing the macro definition, all instances are not updated.
|
||||
|
||||
// - If I have macros \newcommand{\foo}[1]{[#1]} and
|
||||
// \newcommand{\foox}{\foo{x}} then when an instance of \foox is drawn on
|
||||
// screen, there are two black frames. While this is "correct", it is
|
||||
// annoying.
|
||||
|
||||
- LyX crashes when you define a recursive macro
|
||||
|
||||
Misc:
|
||||
|
||||
// - If I have x_{1}^{2}, I put the cursor before the 2, and press backspace,
|
||||
// the result is 'x2'. The correct result should be 'x_{1}2'
|
||||
|
||||
// - If I mark some text and then press ^, then the marked text is deleted.
|
||||
// The correct behavior is to put the marked text in the superscript.
|
||||
|
||||
// - Pressing <down> when cursor is in subscript will move the cursor up
|
||||
// (to the base of the subscript) instead of exiting the inset.
|
||||
// The same problem happen in fractions
|
||||
|
||||
// - When you press the mouse just to the left of the middle point of
|
||||
// some char, the cursor will be positioned to the right of the char.
|
||||
|
||||
pp - It is possible to put two or more consecutive spaces in math text mode
|
||||
|
||||
// - Text in superscript is not smaller than normal text.
|
||||
|
||||
// - After insertion of \sum, the cursor is in invalid location
|
||||
|
||||
// - The height of the frame is often wrong (e.g. x^2)
|
||||
// For example $\sum x$ in an inline formula
|
||||
|
||||
- InsetFormula::validate is broken
|
||||
|
||||
// - Changing math space length by pressing the space-bar key doesn't work
|
||||
!! it's M-m space now.
|
||||
|
||||
// - The drawing of decorations on screen is very different than latex.
|
||||
// (a low priority bug).
|
||||
|
||||
// - If I change '\alpha' to bold, the result is \mathbf{a}
|
||||
|
||||
// - Just moving the cursor in a math inset causes changing the buffer status
|
||||
// to (changed).
|
||||
|
||||
// - disable the insert->label menu item when in inline formula.
|
||||
|
||||
|
||||
Eran Tromer:
|
||||
|
||||
// - When exiting the formula during selection, the anchor moves to the
|
||||
// left of the formula and there's no way to go back.
|
||||
|
||||
// - Scripts are too large. $\log_2$ exceeds inset frame (non-displayed).
|
||||
|
||||
// - You need two <right> to get past \vec{v}, and all sort of other
|
||||
// insetish behavior.
|
||||
|
||||
:: Not a bug.
|
||||
|
||||
// - \vec{several-characters} doesn't work. \overrightarrow does.
|
||||
|
||||
// - When the cursor is in a subscript (and either isn't at the end of
|
||||
// the subscript or there's no subsubscript), pressing <down> should
|
||||
// try to *really* go down (to the next line, or denumerator, or
|
||||
// whatever). Currently it goes *up*. Ditto for superscripts.
|
||||
|
||||
// - When choosing to insert "\left\Vert \right\Vert" parenthesis using
|
||||
// the maths [sic] panel, a "\left( \right." is inserted instead.
|
||||
|
||||
// - Formula inside tabular cell: red frame of cell inset and purple
|
||||
// frame of formula can overlap, causing leftovers when leaving
|
||||
// formula. To get an example, insert a 1x1 tabular into a new document,
|
||||
// enter the cell its cell and press
|
||||
// M-m ( M-f 1 <right> <right> <right> (zoom=100, screenDPI=100)
|
||||
|
||||
// - When selecting multiple cells in a array using the keyboard, <left>
|
||||
// etc. should can move whole cell at a time -- no need to navigate
|
||||
// within cells.
|
||||
|
||||
- When selecting, maybe give a visual indication of the "original"
|
||||
anchor, when it differs from the "actual" one.
|
||||
|
||||
// - Placement of cursor using mouse is seriously broken.
|
||||
// Example 1: large fractions.
|
||||
// Example 2: type into a new document:
|
||||
// "M-d xxxxxxxxx <right> M-x footnote-insert"
|
||||
// Can't reach most places in the formula using mouse.

|

|

- the most annoying bug by far: bold is "inherited" to super and subscripts.
|
||||
|
||||
// - when you get into equation array mode, the previous equation(s)
|
||||
// remain(s) unaligned. I would be soo much faster to have LyX pick the
|
||||
// last equal sign from the previous line as a reference for the alignment
|

// (and a good heuristic for the 80% of cases, with the advantage that we
|
||||
// don't lose anything enforcing it). This is another case that slows down
|
||||
// a lot when typing because, as the previous one, requires going back
|
||||
// and correcting.
|
||||
|
||||
// - the movement is sometimes clumsy inside this arrayed equations: ie.
|
||||
// C-a (or "home" are understood as "beginning of the formula" instead of
|
||||
// "beginning of the equation". Again, a lot of movement has to be made.
|
||||
// I suggest mapping "beginning of doc" with "beginning of formula" and so
|
||||
// on (very intuitive), in case you don't deem appropriate the "namespace

||||
// idea" below.
|

|
||||
//- movement between macro boxes is also weird, but in this one it's perhaps
|
||||
// just me.
|
||||
|

- I suggest creating a different "kewybinding namespace" for the formulas,
|
||||
since you could put to good use all those keybindings from the menu (M-?,
|
||||
C-?) thath currently do their job PLUS getting you out of the formula.

As an aside, you may think that I'm whining over nothing. However, when

4) ERT in math-mode
|

|

Math-mode doesn't handle ERT very well at all. It flips back out of

TeX-mode as soon as you type any special character. Very annoying if I

wish to typeset an \xymatrix inside math-mode (see also my comment above

about table-like environments), since I can't type the &. In fact, my

xymatrices end up as $$\xymatrix{..}$$ in text-mode ERT. Also rather

annoying when you want to use a \macro with more than one argument (but not

fatally so).
