patch 9.1.0094: xxd: buffer-overflow when writing color output Commit: https://github.com/vim/vim/commit/00221487731ea1868c57259c7aa0eb713cd7ade7 Author: Goffredo Baroncelli <kreijack@inwind.it> Date: Sat Feb 10 13:31:06 2024 +0100 patch 9.1.0094: xxd: buffer-overflow when writing color output Problem: xxd: buffer-overflow when writing color output Solution: properly account for the color escape sequences and adjust LLEN macro (Goffredo Baroncelli) xxd: crash with higer number of column xxd writes the data into a buffer before printing. Unfortunately the buffer doesn't consider the space consumed by the escape sequences used to change the color of the character. BEFORE: $ xxd -Ralways -c 256 /etc/passwd Segmentation fault (core dumped) AFTER: $ ./xxd -Ralways -c 256 /etc/passwd 00000000: 726f 6f74 3a78 3a30 3a30 3a72 6f6f 743a 2f72 [...] To solve this issue I had to increase the size of the buffer considering for each byte of data 11 further characters for the color escape sequence. closes: #14003 Signed-off-by: Goffredo Baroncelli <kreijack@libero.it> Signed-off-by: Christian Brabandt <cb@256bit.org>

INSTALLmac.txt - Installation of Vim on Apple MacOS

This file contains instructions for compiling Vim. If you already have an
executable version of Vim, you don't need this.

MacOS Classic is no longer supported.  If you really want it use Vim 6.4.
Only '/' is supported as path separator.


----------------------------------------------------------------------------
Prerequisites
----------------------------------------------------------------------------

Make sure you've installed Xcode and CommandLineTools.  You can download Xcode
from the Mac App Store, for free.

To check for CommandLineTools open a terminal and do:

	$ make --version

If not installed yet a window pops up instructing you to install the developer
tools.

If you don't have the source yet, best is to use git (which you need to
install first), see http://www.vim.org/git.php
Or you can download and unpack the Unix tar archive, see
   http://www.vim.org/download.php


----------------------------------------------------------------------------
Build and install the terminal version.
----------------------------------------------------------------------------

You can compile vim with the standard Unix routine:
   cd vim/src
   make
   make test
   sudo make install

If you get an error "glibtool: command not found" search on stackoverflow for
mac-osx-where-can-i-download-glibtool.

With Homebrew, run:

      brew install libtool

To build libtool from source:

    1. Download the source code from https://www.gnu.org/software/libtool/.

    2. Run these commands from the root of the source code directory:

           ./configure --program-prefix=g
           make
           sudo make install


----------------------------------------------------------------------------
Build and install the GUI version with X-Windows
----------------------------------------------------------------------------

NOTE: this probably no longer works, since Athena support has been removed.

First, install XQuartz, which you can download from https://www.xquartz.org.

To tell configure to use a GUI you can edit the Makefile and uncomment these
two lines (remove the # at the start of the line):

    CONF_OPT_GUI = --enable-gui=athena
    CONF_OPT_DARWIN = --disable-darwin

Do "make distclean" to start with a clean slate.
Then build as with the terminal version above.
Instead of "athena" you can try "gtk2" but you probably need to install GTK
first.


----------------------------------------------------------------------------
Notes
----------------------------------------------------------------------------

Mac-specific configure options are explained in the Makefile:
	--disable-darwin
	--with-mac-arch
