mp-5 (“Minimun Profit Text Editor”) is a multi-language text editor for programmers. It's developed by Angel Ortega.

It features multiple levels of undo, advanced selection capabilities, multiple document editing at once, and has syntax highlighting for many popular programming languages, such as C, C++, Perl, Ruby, HTML, Python, PHP, shell scripts, etc.

You can run it with:

mp-5 file.txt

You can type your text directly into a buffer. Operate the text editor using the mp-5 commands.

If you have configured mp-5 with its ~/.config/mp/mp.mpsl file, you will have a spell checker. Press the F5 key to look up the next word that does not appear in the dictionary, or turn on the display of misspelled words from the Writing Menu / Toggle Spelling.

Save your changes with Ctrl+s. Exit the editor with Ctrl+q.

mp-5 has three different Selection Modes: “Block”, “Corner” and “Move”. These allows to select a region of text and operate it according to the editing commands. The Find, Replace, etc. operations will be applied only to the selected text region (if you choose one).

It will be possible to extend the selected text region as much as you want.

You can deselect the text region by pressing F8, or when you copy, delete, or replace the block.

To select a region of text in a block, move to the start position of the text and mark it with F9; then move to the end position of the text and mark it by pressing F9 again.

The text block will be highlighted, and will act as a selected text region. Vertex Selection Mode

To select a vertical region of text, move to the start vertex and press Ctrl+b; then move to the end vertex position and mark it by pressing Ctrl+b again. A vertical rectangle of text will be highlighted between the two vertices, and will act as a selected text region.

This mode does not work on remote terminals, but it will work in a local viewport.

To select a region of text in the conventional way, hold down the Shift key and use mp-5's movement shortcuts.

mp-5 adds some interesting features useful for writing programming code, allowing it to be integrated as a simple integrated development environment (IDE).

If you are working with git, you can request version control using Ctrl+p, or search for programming tags with Ctrl+t.

You can invokes the compilation of a project, with the Build function (F2 key). If a makefile exists in the current working directory, all object files will be extracted and a list will be displayed. Choose the desired one and a make will be performed, the result of which will be displayed on the screen as a read-only document (for analysis). If compilation errors or warnings appear, you can navigate between them by moving forward with F3 and backward with Ctrl+F3.
