[`dte`](https://craigbarnes.gitlab.io/dte/) is an interesting editor I started using
lately more and more. Since it is using [`execvp()`](https://linux.die.net/man/3/execvp)
it can be easily extended. I needed comment/uncomment feature so I created a
small utility that does this for me. Code lives on repository
[dte extensions](https://git.mitjafelicijan.com/dte-extensions.git/about/)
but this utilities can be used for whatever you want. Make sure you have
version 1.11 or above.
Next one will be invoking formatter based on the type of a file.
My config that works for me.
```sh
set show-line-numbers true;
set tab-width 4;
set case-sensitive-search false;
# Special aliases
alias m_comment 'exec -s -i line -o buffer -e errmsg ~/.dte/bin/comment'
alias m_format 'save; exec go fmt .; reload'
alias m_duplicate 'copy;paste';
# Useful aliases.
alias m_force_close 'quit -f';
alias m_reload 'close; open $FILE'
# Key bindings.
bind M-s save;
bind M-q m_force_close;
bind M-z refresh;
bind C-down blkdown;
bind C-up blkup;
bind C-_ m_comment;
bind M-. m_format;
bind C-d m_duplicate;
# Syntax highlighting.
hi preproc magenta;
hi keyword red;
hi linenumber blue;
hi comment cyan;
