• UI themes, file extension .cuda-theme-ui
    • Syntax themes, file extension .cuda-theme-syntax
    • Call dialog: "Options/ Settings - more/ Settings - theme - nnnnn"
    • For UI themes: customize colors in dialog
    • For syntax themes: customize lexer-styles in dialog
    • For syntax themes: test theme at last on JS/HTML/CSS/C/Pascal/Ini/Markdown/Go lexers.
      • You can use sample codes in the Lexer Properties dialog.
      • You can use sample files from
    • New theme files are saved in the subdir "data/themes"
    • Make such file "install.inf":
    • Make zip file "theme.MyName.zip" with files "MyTheme.cuda-theme-nnnnn" and "install.inf"
    • Test zip file: open zip file in CudaText, confirm installation
    • Publish file at forum or https://github.com/Alexey-T/CudaText/issues
    • "editor, font" - color of font when no lexer is active. Click statusbar field with lexer-name, call "none".
    • "editor, disabled state, font/bg" - editor shown with this bg-color when Replace dialog runs action, with option "confirm on replace" (during confirm message editor is disabled), if no lexer active
    • "statusbar alt" - shown on 2nd statusbar, run in console:
    • "search progressbar" - to see it, call Replace dlg, with regex, with confirmation (2 options in Replace dlg), replace "." (any char) to "www"
    • "editor, markers" - to see markers, call Commands dlg (F1), command "drop marker at caret".
    • "editor, separator lines" - lines show eg for lexer Pascal, above "function"/"procedure".
    • "listbox, …" - call Commands dlg (F1 key)
    • "listbox, …, auto-complete…" - call C or Pascal lexer, then press Ctrl+Space to call auto-completion (listbox has 3 columns, 3rd shows not for all items)
    • "splitters, main" - shown near Sidebar (vertical) and above Bottom panel (horizontal)
    • "splitters, groups" - shown between groups (vert/horz), activate 2-3 groups using "View" menu

    • Id2: Special id, used e.g. for syntax constants (true, false, null…) and standard functions (sin, abs, max…).
    • Id3: Special id, used e.g. for measurement units (mm, Kb, px…) and preprocessor directives.
    • Id4: Special id, rarely used, e.g. Python uses it for function names after "def".
    • IdKeyword: Special id, used for syntax keywords.
    • IdVar: Variables, e.g. $name in PHP and Bash.
    • IdBad: Incorrect/misslepped id.
    • String: String literals.
    • String2: String literals, used e.g. for RegEx constants.
    • String3: String literals, one more kind, rarely used.
    • Symbol: Non-word symbols, ie brackets/punctuation/etc.
    • Symbol2: Non-word symbols, used when syntax needs another style for e.g. assignment/math operators.

    • Color: Color constants, like #RRGGBB in HTML/CSS.

    • BracketBG: Style with background+foreground colors. Used to highlight paired brackets, begin/end keywords, repeat/until keywords (when "dynamic highlighting" option is on) etc.
    • CurBlockBG: Style with background color set, foreground color unset. Used to highlight block under caret, when "dynamic highlighting" option is on.
    • SeparLine: Color of horizontal 1-pixel separator lines. Was used before in Pascal, for lines above functions.
    • TagBound: HTML tags: angled brackets.
    • TagId: HTML tags: tag names.

    • TagProp: HTML tags: properties/attributes of tags, before "=" char.
    • TagPropBad: HTML tags: incorrect props/attrs of tags.
    • TagInclude: Tags used for inclusion of sub-lexer blocks. Used e.g. in PHP, .
    • LightBG#: Styles with bright background color, and normal foreground. Used e.g. in Diff to highlight deleted (LightBG1) / changed (LightBG2) / added (LightBG3) text blocks.
