Functions used to create and manipulate textblock objects.
Unlike Text Object Functions, these handle complex text, doing multiple styles and multiline text based on HTML-like tags. Of these extra features will be heavier on memory and processing cost.
This part explains about the textblock object's API and proper usage. The main user of the textblock object is the edje entry object in Edje, so that's a good place to learn from, but I think this document is more than enough, if it's not, please contact me and I'll update it.
The textblock objects is, as implied, an object that can show big chunks of text. Textblock supports many features including: Text formatting, automatic and manual text alignment, embedding items (for example icons) and more. Textblock has three important parts, the text paragraphs, the format nodes and the cursors.
You can use markup to format text, for example: "<font_size=50>Big!</font_size>". You can also put more than one style directive in one tag: "<font_size=50 color=#F00>Big and Red!</font_size>". Please notice that we used "</font_size>" although the format also included color, this is because the first format determines the matching closing tag's name. You can also use anonymous tags, like: "<font_size=30>Big</>" which just pop any type of format, but it's advised to use the named alternatives instead.
A textblock Cursor is data type that represents a position in a textblock. Each cursor contains information about the paragraph it points to, the position in that paragraph and the object itself. Cursors register to textblock objects upon creation, this means that once you created a cursor, it belongs to a specific obj and you can't for example copy a cursor "into" a cursor of a different object. Registered cursors also have the added benefit of updating automatically upon textblock changes, this means that if you have a cursor pointing to a specific character, it'll still point to it even after you change the whole object completely (as long as the char was not deleted), this is not possible without updating, because as mentioned, each cursor holds a character position. There are many functions that handle cursors, just check out the evas_textblock_cursor* functions. For creation and deletion of cursors check out:
The textblock object is made out of text splitted to paragraphs (delimited by the paragraph separation character). Each paragraph has many (or none) format nodes associated with it which are responsible for the formatting of that paragraph.
As explained in Textblock Object Paragraphs each one of the format nodes is associated with a paragraph. There are two types of format nodes, visible and invisible: Visible: formats that a cursor can point to, i.e formats that occupy space, for example: newlines, tabs, items and etc. Some visible items are made of two parts, in this case, only the opening tag is visible. A closing tag (i.e a </tag> tag) should NEVER be visible. Invisible: formats that don't occupy space, for example: bold and underline. Being able to access format nodes is very important for some uses. For example, edje uses the "<a>" format to create links in the text (and pop popups above them when clicked). For the textblock object a is just a formatting instruction (how to color the text), but edje utilizes the access to the format nodes to make it do more. For more information, take a look at all the evas_textblock_node_format_* functions. The translation of "<tag>" tags to actual format is done according to the tags defined in the style, see evas_textblock_style_set
Textblock supports various format directives that can be used in markup. In addition to the mentioned format directives, textblock allows creating additional format directives using "tags" that can be set in the style see evas_textblock_style_set .
For more details see Evas Textblock Style Options
Textblock supports the following formats:
A textblock style object.
A textblock cursor object, used to maipulate the cursor of an evas textblock.

Returns the geometry of two cursors ("split cursor"), if logical cursor is between LTR/RTL text, also considering paragraph direction.
Upper cursor is shown for the text of the same direction as paragraph, lower cursor - for opposite.
Split cursor geometry is valid only in '|' cursor mode. In this case EINA_TRUE
is returned and cx2, cy2, cw2, ch2 are set, otherwise it behaves like cursor_geometry_get.

Returns the geometry of the cursor.
Depends on the type of cursor requested. This should be used instead of char_geometry_get because there are weird special cases with BiDi text. in '_' cursor mode (i.e a line below the char) it's the same as char_geometry get, except for the case of the last char of a line which depends on the paragraph direction.
in '|' cursor mode (i.e a line between two chars) it is very variable. For example consider the following visual string: "abcCBA" (ABC are rtl chars), a cursor pointing on A should actually draw a '|' between the c and the C.
