Emacs compilation

A wild tale tells lucid works better than gtk3 when using emacs daemon. These are the suggested compilation flags:

sudo apt-get install build-essential texinfo libx11-dev libxpm-dev libjpeg-dev libpng-dev libgif-dev libtiff-dev libncurses5-dev libxaw7-dev libgnutls28-dev libxft-dev libharfbuzz-dev libxfixes-dev libxrandr-dev libxinerama-dev ttf-mscorefonts-installer npm libvterm-bin libvterm-dev libvterm0 libtool libtool-bin cmake libsystemd-dev libsystemd0 libotf-dev
wget https://ftp.gnu.org/gnu/emacs/emacs-27.1.tar.xz
tar -xf emacs-27.1.tar.xz
cd emacs-27.1
git apply xterm.c.27.1.patch
./configure --with-x-toolkit=lucid --with-kerberos --with-kerberos5 --with-wide-int --with-mailutils --with-modules --with-libotf --with-libsystemd --enable-checking=yes,glyphs --with-file-notification=yes 'CFLAGS=-O2'
make
sudo make install
systemctl --user enable emacs
sudo npm -g install js-beautify

git clone https://github.com/akermu/emacs-libvterm.git
cd emacs-libvterm
mkdir -p build
cd build
cmake ..
make
cd ..
cp vterm-module.so ~/.emacs.d/lisp/vterm-module.so
cp vterm.el ~/.emacs.d/lisp/vterm.el
cp etc/emacs-vterm-bash.sh ~/.emacs.d/lisp/emacs-vterm-bash.sh

Bash epc completion

wget https://ftp.gnu.org/gnu/bash/bash-5.1.tar.gz
tar -xf bash-5.1.tar.gz
cd bash-5.1
git apply bash_epc_completion.patch
./configure
make pathnames.h
cd examples/loadables
make epc_completion
cp epc_completion ~/.emacs.d/lisp/bash_epc_completion
# enable -f ./epc_completion epc_completion
# enable -d epc_completion

GDB completion / context

The context command is provided by GEF and then sent to emacs using epc.

Python completion

Support following python and completion from python interpreter.

GDB / IDA decompiler integration

Have your ida on one machine with epc server running:

cd sysroot-of-binaries
python -m epc.server --address 0.0.0.0 --port 19999 builtins

The have your gdb init configure this machine ip:

gef config ida-interact.host "192.168.99.1"

And then you will be able to see one window with the decompiled code from ida and for each decompiled code you can see its assembly (press TAB on a source code line to see the assembly).
