ANSI Escape Codes Seemingly not Working #61

Closed Garash2k closed 1 year ago

Garash2k commented 1 year ago

Hi! I'd like to use Scintilla.NET to be able to show colored git diff results. TortoiseGit uses scintilla to that effort so it should be possible in theory.

In SciTE, after adding a lexer.errorlist.escape.sequences=1 property in an options file, and setting the lexer to Errorlist via the Language menu, the escape codes are parsed fine. git diff --color=always.txt image

However, despite setting the property to 1 and using errorlist as our lexer, the escape codes are still shown as is, instead of being interpreted. image image

Am I missing something or is there something that could be improved to make them work?

Interesting 🤔I need to investigate this a bit deeper, might take a while - I'm getting exactly same results, but the Scintilla control should be able to display ANSI escape sequences with colors, see: https://sourceforge.net/p/scintilla/bugs/2161/.

Hi, The Lexer must be styled as by default the styles are nowhere. The code:

scintilla.StyleClearAll();
var text = File.ReadAllText(@"C:\Users\Petteri Kautonen\Downloads\git.diff.--color.always.txt");
scintilla.LexerName = "errorlist";

var errorBackground = Color.FromArgb(0xFF, 0xF7,0xE7);

// Default
scintilla.Styles[0].ForeColor = Color.Black;
// python Error
scintilla.Styles[1].ForeColor = Color.FromArgb(0xff, 0x00, 0x00);
// gcc Error
scintilla.Styles[2].ForeColor = Color.FromArgb(0x80, 0x00, 0x80);
// Microsoft Error
scintilla.Styles[3].ForeColor = Color.FromArgb(0x80, 0x80, 0x00);
// command or return status
scintilla.Styles[4].ForeColor = Color.FromArgb(0x00, 0x00, 0xFF);
// Borland error and warning messages
scintilla.Styles[5].ForeColor = Color.FromArgb(0xB0, 0x60, 0x00);
// perl error and warning messages
scintilla.Styles[6].ForeColor = Color.FromArgb(0xFF, 0x00,0x00);

scintilla.Styles[23].BackColor = errorBackground;

scintilla.Styles[23].Visible = false;

scintilla.Styles[40].ForeColor = Color.FromArgb(0x00, 0x00,0x00);

scintilla.Styles[45].BackColor = errorBackground;

scintilla.Styles[46].BackColor = errorBackground;

scintilla.Styles[51].BackColor = errorBackground;
scintilla.Styles[51].Bold = true;
scintilla.Styles[52].ForeColor = Color.FromArgb(0x00, 0x00,0x80);
scintilla.Styles[52].BackColor = errorBackground;
scintilla.Styles[52].Bold = true;
scintilla.Styles[53].ForeColor = Color.FromArgb(0x80, 0x00,0x80);
scintilla.Styles[53].BackColor = errorBackground;
scintilla.Styles[53].Bold = true;
scintilla.Styles[54].ForeColor = Color.FromArgb(0x00, 0x80,0x80);
scintilla.Styles[54].BackColor = errorBackground;
scintilla.Styles[54].Bold = true;
scintilla.Styles[55].ForeColor = Color.FromArgb(0xA0, 0xA0,0xA0);
scintilla.Styles[55].BackColor = errorBackground;
scintilla.Styles[55].Bold = true;

scintilla.SetProperty("lexer.errorlist.escape.sequences", "1");
scintilla.SetProperty("lexer.errorlist.value.separate", "1");

scintilla.Text = text;

The code piece that hides the escape symbol in the above is:

scintilla.Styles[23].Visible = false;

I read this from the Scintilla source code, see others.properties file in the SciTe source code: ...

...

As a result I get this: image

NOTE: The provided C# code doesn't include font family changes. Let me know if this answered your question 🙂
