A Midnight Commander fork with scripting and other features.


⁝⁝⁝ ⋱הϵѻ⋱ Midnight Commander ⁝⁝⁝

Welcome to the ⋱Neo⋱-MC project! The goals of it are to:

  • make the hidden gem – mcedit – shine and grow to be able to compete with Vim and Emacs,
  • add a scripting language to mcedit and mc to make this possible,
  • add some meaningful plugins written in the scripting language.

Check out MCEditWishList for a curated list of the planned enhancements. Maybe you would want to implement one of them? Because patches are welcomed, so as are new contributors.

⋱ New Features Added By The Fork ⋱

Multi Search – AND-chained Grepping (Filtering) Of Any Listbox

On Ctrl-Space an input field for a search query will be added under the currently displayed listbox. Entering any text into it will cause only the matching (i.e.: containing) elements in the listbox to be displayed – the rest will be removed. The query can be multi word (all must match). Also, entering just the letter 'c' or 'h' will automatically filter entries that end on '.c' or '.h', respectively (it also looks for .cpp and .hpp extensions).

MultiSearch can be enabled by default on all listboxes via the option multi_search_active_by_default=true.

Listing Of TAGS Symbols

A feature that pairs up with MultiSearch – an ability to list of all ctags symbols for the current file:

  • to list all functions – press alt-shift-f,
  • … all variables defined in the file – press alt-shift-v,
  • … all type definitions … – press alt-shift-t,
  • … all remaining types of entities (e.g.: C macros) … – press alt-shift-o,
  • … all symbols regardless of their type – press alt-shift-a.

After selecting of an entry the cursor and display will jump to it. With MultiSearch you can quickly find the declaration that you want by grepping the list.

Completion From All Open Files

The completion has been extended to propose words from all open files, not only from the currently edited one.

Viewport Centering

A new action called CenterView has been added. By pressing Alt-c the currently edited line of text will be positioned in the middle of the screen (i.e.: the viewport will be scrolled).

Window Cascading And Tiling

When Ctrl-Alt-c will be pressed then all windows with opened files will exit fullscreen and be automatically arranged in a cascade. Ctrl-Alt-t arranges them in a tiling configuration.

Also, new options -w/--cascade and -T,--tile will make the editor to start up with the selected arrangement. Also, there are a two new entries added to the Window sub-menu.

S-Lang Scripting support.

The already linked libslang.so contains a robust, light scripting language interpreter. This fork utilizes it (and the excelent C script binding generator Slirp) to provide a compact, light scripting support for Midnight Commander. The API is currently yet small and focused on the editor, however it'll grow. A PDF containing a description of current interface functions is available.

There are 3 example plugins in subdirectory misc/:

  • capitalize.plugin.sl – capitalizes the current word (alt-shift-c),
  • commentify.plugin.sl – wraps current line with /* and */ (alt-i),
  • grow_shrink_integer.plugin.sl – adds the Vim well known growing and decreasing of a number under cursor (Alt-a and Alt-x).

To use them, place them in ~/.config/mc/plugin directory. Also an init.sl file is being loaded at startup – it should be placed in the directory: /usr/local/etc/mc/init.sl (or /etc/mc/init.sl, depending on the installation prefix).

CLI window

There's a new command line like window called Instruction Station, bound to Alt-i by default. It runs /bin/bash by default and allows to interactively run commands and view their output.

Sqrt OS is a simulation of an OS scheduler and memory manager using different scheduling algorithms including Highest Priority First (non-preemptive), Shortest Remaining Time Next, and Round Robin.

A CPU scheduler determines an order for the execution of its scheduled processes; it decides which process will run according to a certain data structure that keeps track of the processes in the system and their status. A process, upon creation, has one of the three states: Running, Ready, Blocked (doing I/O, using other resources than CPU or waiting on unavailable resource).
