Code Editor : textprop.txt

*textprop.txt*  For Vim version 8.1.  Last change: 2019 Oct 23

VIM REFERENCE MANUAL    by Bram Moolenaar

Displaying text with properties attached.	*textprop* *text-properties*

{not able to use text properties when the |+textprop| feature was
disabled at compile time}

==============================================================================
1. Introduction						*text-prop-intro*

Text properties can be attached to text in a buffer.  They will move with the
text: If lines are deleted or inserted the properties move with the text they
are attached to.  Also when inserting/deleting text in the line before the
text property.  And when inserting/deleting text inside the text property, it
will increase/decrease in size.

The main use for text properties is to highlight text.  This can be seen as a
replacement for syntax highlighting.  Instead of defining patterns to match
the text, the highlighting is set by a script, possibly using the output of an
external parser.  This only needs to be done once, not every time when
redrawing the screen, thus can be much faster, after the initial cost of
attaching the text properties.

Text properties can also be used for other purposes to identify text.  For
example, add a text property on a function name, so that a search can be
defined to jump to the next/previous function.

A text property is attached at a specific line and column, and has a specified
length.  The property can span multiple lines.

A text property has these fields:
	"id"		a number to be used as desired
	"type"		the name of a property type

Property Types ~
							*E971*
A text property normally has the name of a property type, which defines 
how to highlight the text.  The property type can have these entries:
	"highlight"	name of the highlight group to use
	"combine"	when TRUE the text property highlighting is combined
			with any syntax highlighting, when omitted or FALSE the
			text property highlighting replaces the syntax
			highlighting
	"priority"	when properties overlap, the one with the highest
			priority will be used.
	"start_incl"	when TRUE inserts at the start position will be
			included in the text property
	"end_incl"    	when TRUE inserts at the end position will be
			included in the text property

Example ~

Suppose line 11 in a buffer has this text (excluding the indent):

The number 123 is smaller than 4567.

To highlight the numbers in this text: >
	call prop_type_add('number', {'highlight': 'Constant'})
	call prop_add(11, 12, {'length': 3, 'type': 'number'})
	call prop_add(11, 32, {'length': 4, 'type': 'number'})

Try inserting or deleting lines above the text, you will see that the text
properties stick to the text, thus the line number is adjusted as needed.

Setting "start_incl" and "end_incl" is useful when white space surrounds the
text, e.g. for a function name.  Using false is useful when the text starts
and/or ends with a specific character, such as the quote surrounding a string.

func FuncName(arg) ~
	     ^^^^^^^^        property with start_incl and end_incl set

var = "text"; ~
	      ^^^^^^	     property with start_incl and end_incl not set

Nevertheless, when text is inserted or deleted the text may need to be parsed
and the text properties updated.  But this can be done asynchronously.

Internal error *E967*

If you see E967, please report the bug.  You can do this at Github:
https://github.com/vim/vim/issues/new

2. Functions						*text-prop-functions*

Manipulating text property types:

prop_type_add({name}, {props})		define a new property type
prop_type_change({name}, {props})	change an existing property type
prop_type_delete({name} [, {props}])	delete a property type
prop_type_get([{name} [, {props}])	get property type values
prop_type_list([{props}])		get list of property types

Manipulating text properties:

prop_add({lnum}, {col}, {props})  	add a text property
prop_clear({lnum} [, {lnum-end} [, {bufnr}]])
					remove all text properties
prop_find({props} [, {direction}])	search for a text property
prop_list({lnum} [, {props})  		text properties in {lnum}
prop_remove({props} [, {lnum} [, {lnum-end}]])
					remove a text property

*prop_add()* *E965*
prop_add({lnum}, {col}, {props})
		Attach a text property at position {lnum}, {col}.  {col} is
		counted in bytes, use one for the first column.
		If {lnum} is invalid an error is given. *E966*
		If {col} is invalid an error is given. *E964*

{props} is a dictionary with these fields:
		   length	length of text in bytes, can only be used
				for a property that does not continue in
				another line; can be zero
		   end_lnum	line number for the end of text
		   end_col	column just after the text; not used when
				"length" is present; when {col} and "end_col"
				are equal, and "end_lnum" is omitted or equal
				to {lnum}, this is a zero-width text property
		   bufnr	buffer to add the property to; when omitted
				the current buffer is used
		   id		user defined ID for the property; when omitted
				zero is used
		   type		name of the text property type
		All fields except "type" are optional.

It is an error when both "length" and "end_lnum" or "end_col"
		are given.  Either use "length" or "end_col" for a property
		within one line, or use "end_lnum" and "end_col" for a
		property that spans more than one line.
		When neither "length" nor "end_col" are given the property
		will be zero-width.  That means it will not be highlighted but
		will move with the text, as a kind of mark.
		The property can end exactly at the last character of the
		text, or just after it.  In the last case, if text is appended
		to the line, the text property size will increase, also when
		the property type does not have "end_incl" set.

"type" will first be looked up in the buffer the property is
		added to. When not found, the global property types are used.
		If not found an error is given.
