• gedit (Gnome) and kate (KDE) are both decent editors. ( Gedit has a nice dark colour scheme you can pick to use. )
• Meld and Kompare are decent diff tools
• KDESvn is what I used to use to sync with SVN in KDE.

• notepad++ is quite a good GPL editor.
• Tortoise SVN is good for doing SVN checkouts and commits.
• WinMerge is a decent GPL diff tool.
• 7-zip is a pretty handy archiver.

On Ubuntu Linux, G uses:

• grep

export GREP_COLOR='1;33'
export GREP_OPTIONS=--color=auto

• colordiff

alias svndiff='(echo "Running SVN diff (your changes vs. the repo)..." && (svn -x -w diff|colordiff))|less -R'
alias svnbasediff='(echo "Running SVN diff against BASE:HEAD (changes in the repo since last \"svn update\")..." && (svn diff -x -w -rBASE:HEAD|colordiff))|less -R'

• diff -y with automatic adjustment for term width.

alias ydiff='y_diff'
function y_diff() {
  diff --width=${COLUMNS} -b -y "$1" "$2" | colordiff | less -R
}

• colormake & colorgcc

### Color GCC

  export CC="colorgcc"
  alias gcc='colorgcc'

    if [ ! -e /usr/local/bin/${C} ]; then
      echo "Installing colorgcc wrapper in /usr/local/bin for ${C}... "
      sudo ln -s /usr/bin/colorgcc /usr/local/bin/${C}
    fi

• source-highlight
• Usage:
  • vs somefile.cpp
  • vs SConscript

alias vs="view_source"
function view_source {

• nano editor with color syntax highlighting

• Syntax color highlighting .nanorc file, you may have to run dos2unix on it.

• Usage:
  • nano somefile.cpp:326:error: some compiler error message

alias nano='smart_nano'
## Smart nano jumps to a line number when you give it filename:nnn where nnn is the line number (like compile warnings/errors)
function smart_nano() {
  if [ -z "$(echo \"$@\" | egrep [a-zA-Z0-9]:[0-9]+)" ]; then
    /usr/bin/nano -w -c "$@"
    return
  fi
  unset args
  echo
  while (( "$#" )); do
    if [ ! -z "${1}" ] && [ ! -z "`echo ${1}|cut -d: -f2|grep -e '^[0-9]*$'`" ]; then
      args[${#args[@]}]=+$(echo ${1}|cut -d: -f2|grep -e '^[0-9]*$') # Line Number Offset
      args[${#args[@]}]=$(echo ${1}|cut -d: -f1) # File Name
    elif [ -f "${1}" ]; then
      args[${#args[@]}]=$1
    else
      echo "Nano could not find: $1"; sleep .5
    fi
    shift
