preliminary stuff.

Remote Display

Ping from PI

Set up as following:

wifi (internet)
eth0 (EtherCAT master): default
eth1 (Windows PC, USB-Ethernet Adapter): static ip_address=10.0.0.2
(use etc/dhcpcd.conf, not /etc/network/interfaces.)
Configure the Windows firewall to allow pings
public: File and Printer Sharing (Echo Request - ICMPv4-In).
If necessary, Setup a DHCP server for PI
(ATTN: in Raspberry-Pi, setup DHCP-IP may affect routing to wifi!!!, so static-IP is preferred!)

Cursor

Also used to mean the current line.

An indicator used to know the position in the text.

This is useful when a pattern occurs many times in the text: it enables the editor to select the wanted one.

The cursor also enables to manipulate the selected element.

Directions

Here's the vocabulary to locate something relatively in a collection of lines.

above

Should be prefered over the words over, before, previous or up.

below

Should be prefered over the words under, after, next or down.

Editor

Also called "text editor".

A piece of software which is able to change the content of a text. In the case of Redaktilo, the editor is an object provided by a library.

File

Also called "text file", to be opposed to "binary file".

See Text.

Line

The unit with which Redaktilo works. It's a simple string which ends at the line break:

\r\n for texts created on Windows
\n for texts created on the other operating systems

To make it easier for the developers, Redaktilo takes care of the line break, so you should only provide it with a string stripped of it.

Location

The given line number, to which you can relatively search or do something.

Redaktilo

This means editor in esperanto. Technically Tekstoredaktilo should have been used (text editor), but it was a bit too long for a project name.

Text

Can contain:

plain text
JSON
YAML
PHP
etc...
