A few days ago I found a misbehavior related to the list-color-display command. I have made further investigations and finally figured out, that the problem is caused by the build process, I have used (by accident).
When I run the build commands as descibed in nextstep/INSTALL everything works fine:
./configure --with-ns make make installAnd this is the command sequence which builds a Emacs.app with the described problem:
./configure --with-ns sudo make sudo make install Markus On 06/03/2010 23:07, Markus Prepens wrote:
When I evaluate (defvar my-x-colors (ns-list-colors)) the complete color list is put to my-x-colors. I think your impression is right: The code is correct, but the calling order during startup might be the problem. Maybe this is a hint: Step 1: Startup Emacs with the -Q switch Step 2: Enter M-: (setq x-colors (ns-list-colors)) Step 3: Enter M-x list-colors-display and the complete list of all colors appears in the *Colors* buffer. Without step 1 and 2 the *Colors* buffer shows only 37 colors. I make further investigations, what is going on. Any hints are welcome ...

I stepped down the code to xw-defined-colors in file ns-win.el. It uses the list x-colors. It contains only 42 colors. x-colors is initialized with the return value of ns-list-colors: (defvar x-colors (ns-list-colors) What I am wondering about is that ns-list-colors returns a correct list of 794 colors. What is wrong with the assignment of (ns-list-colors) to x-colors?Nothing's wrong. I suspect that some code modifies x-colors after it is assigned. Can you see if evaluating the following form (defvar my-x-colors (ns-list-colors)) puts the full 794-color list in my-x-colors? (To evaluate the expression, put the cursor immediately after the right parenthesis and type "C-x C-e".)
