8.52 Syntax Coloring

Syntax Color Break Euphoria statements into words with multiple colors. The editor and pretty printer (eprint.ex) both use this file.

8.52.1 Routines

8.52.1.1 set_colors

include euphoria/syncolor.e
namespace syncolor
public procedure set_colors(sequence pColorList)

8.52.1.2 init_class

include euphoria/syncolor.e
namespace syncolor
public procedure init_class()

8.52.1.3 new

include euphoria/syncolor.e
namespace syncolor
public function new()

Create a new colorizer state

reset, SyntaxColor

8.52.1.4 reset

include euphoria/syncolor.e
namespace syncolor
public procedure reset(atom state = g_state)

8.52.1.5 keep_newlines

include euphoria/syncolor.e
namespace syncolor
public procedure keep_newlines(integer val = 1, atom state = g_state)

8.52.1.6 SyntaxColor

include euphoria/syncolor.e
namespace syncolor
public function SyntaxColor(sequence pline, atom state = g_state, multiline_token multi = 0)

Parse Euphoria code into tokens of like colors.

Parameters:

1. pline the source code to color
2. state (default g_state) the tokenizer to use
3. multi the multiline token from the previous line

Break up a new-line terminated line into colored text segments identifying the various parts of the Euphoria language. They are broken into separate tokens.

Returns:

A sequence that looks like:

{color1, "text1"}, {color2, "text2"}, ... }

Comments:

In order to properly color multiline syntax (strings and comments), you should pass a value for multi. This value can be attained by calling last_multiline_token after coloring the previous line.
