Programmer's Interactive Editor

===============================



Emacs-like Erlang editor fully written in Erlang with S-Lang driver.

It is refined and ready to run on R16B01 with built-in sync and lager.

Pie codebase is very tiny, clean and extendable.

--------



Pie suports Extended Kystrokes and CUA mode being general purpose

editor saving your hands from RSI.



    CURSOR            -- Navigation

    HOME (Fn-LEFT)    -- Begining of line

    END  (Fn-RIGHT)   -- End of line

    PGUP (Fn-UP)      -- Page up

    PGDN (Fn-DOWN)    -- Page down



Selection

    

    S-CURSOR    -- Selection

    C-S-LEFT    -- Begining of line

    C-S-RIGHT   -- End of line

    M-S-LEFT    -- Word left

    M-S-RIGHT   -- Word right

    S-PGUP/PGDN -- unbinded

    

Copy & Paste



    M-c -- Copy

    M-v -- Paste



Remember that Pie is an Emacs (Erlang Macros) editor thus

it supports all basic Emacs commands which you can find

in edit_globalmap bindings. Here are most important:



File Operations

---------------



    C-x C-c -- Quit

    C-x C-f -- Find File, supports autocompletion in popup-windows

    C-x C-s -- Save File



Window Management

-----------------



    C-x o   -- Next Window

    C-x 0   -- Delete selected Window

    C-x 1   -- Delete other Windows

    C-x 2   -- Vertical Split 

    

Pie Commands

------------



    M-x     -- will run internal Pie command in module:function format.

               E.g. you can type "edit_lib:scroll_up"



For developing Pie commands a parse_transform syntax was introduced.

Here is example of edit_lib:unix_command



    -command({unix_command, [{shell_command, "Shell command:"}]}).

    unix_command(State, Cmd) ->

        Text = os:cmd(["sh -c '(cd ",edit_util:pwd(State)," ; ",Cmd,")'"]),

        edit_util:popup_message(State, '*Shell Command Output*', Text).



State is mandatory first argument of Pie state.



Eval

----



    M-:     -- command will evaluate Erlang Expression in the minibuffer,

               like "os:type()." or "lists:seq(1,100).". If output is

               not fit into one line another window will be created.



Interactive Mode

----------------



    C-x i   -- command will enter Erlang Interactive shell 

               where you can evaluate Erlang expressions 

               inside editor buffer by pressing ENTER on them.

               The result would be displayed also in the 

               editor buffer below.



                    os:type(). ENTER

                    => {unix,linux}

                    >>



Fundamental Mode

----------------



    C-x f   -- command will bring you back to Fundamental mode which

               is defaul editing mode.



Erlang Mode

-----------



    C-x e   -- command will dive you into Erlang mode which helps you edit Erlang code.

    C-i     -- reformat selected code
