It seems I found solution (optional, don't works by default): ```diff --- scintilla/lexers/LexLisp.cxx Wed Mar 07 00:46:38 2018 +++ scintilla/lexers/LexLisp.cxx Wed Mar 07 00:42:04 2018 @@ -86,6 +86,8 @@ char chNext = styler[startPos]; Sci_PositionU lengthDoc = startPos + length; styler.StartSegment(startPos); + /*gettext shorthand for Scheme, GIMP Script-Fu extension*/ + bool scriptfu = styler.GetPropertyInt("lexer.scheme.scriptfu") == 1; for (Sci_PositionU i = startPos; i < lengthDoc; i++) { char ch = chNext; chNext = styler.SafeGetCharAt(i + 1); @@ -103,6 +105,11 @@ styler.ColourTo(i - 1, state); radix = -1; state = SCE_LISP_MACRO_DISPATCH; + } + /*gettext shorthand for Scheme, GIMP Script-Fu extension*/ + else if (scriptfu && ch == '_' && chNext == '"') { + styler.ColourTo(i - 1, state); + state = SCE_LISP_DEFAULT; } else if (ch == ':' && isLispwordstart(chNext)) { styler.ColourTo(i - 1, state); state = SCE_LISP_SYMBOL;
``` And it requires two new strings in ```filetypes.Scheme.conf```: ```ini [lexer_properties=Lisp] lexer.scheme.scriptfu=1 ```
