Creating a simple vim syntax highlighting

syntax highlightingvim

i have a simple sort of a database file which consists only of entries in the following format


i want to create a simple vim syntax highlighting for it and set it for specific file extension

for instance, variable part could be light blue, and value part light red

i googled it and came across things such as $vimruntime\syntax\, syntax set=, syntax match, and hi keywords, but couldn't set it up myself eventually

so i want a very simple vim code snippet that would realize it by matching the left and right hand sides and coloring them separately

    3. Put the following in $HOME/.vim/syntax/foo.vim:

      syntax match FooKey   /^[^=]\+/
      syntax match FooValue /[^=]\+$/
    4. Put the following lines at the very end of $HOME/.vimrc (or at least after any colorscheme line):

      highlight FooKey   ctermfg=cyan guifg=#00ffff
      highlight FooValue ctermfg=red  guifg=#ff0000
    5. Make sure you have the following line somewhere in your ~/.vimrc:
