All text is synchronized in an [encrypted](http://bitwiseshiftleft.github.io/sjcl/) state. I had a similar use case to [SDEES](https://news.ycombinator.com/item?id=12441302) ([Code on GitHub](https://github.com/schollz/sdees)), but needed a zero-install, browser-based solution. 5 | 6 | [Try it!](https://srpeck.github.io/encryptedgist/index.html) 7 | 8 | The editor is customized to my personal usage - CodeMirror in Vim mode for pure plaintext notetaking across multiple fixed-configuration machines (VDI, etc.). Often this includes confidential notes that I do not want to share with Google/Microsoft/GitHub, hence SJCL client-side encryption. Depending on your usage, you may want to inline everything in a single HTML file and/or add localStorage for offline/single-machine use, similar to [Encrypted](https://github.com/srpeck/encrypted). 9 | 10 | ![](demo.gif) 11 | 12 | MIT License 13 | -------------------------------------------------------------------------------- /codemirror.css: -------------------------------------------------------------------------------- 1 | /* BASICS */ 2 | 3 | .CodeMirror { 4 | /* Set height, width, borders, and global font properties here */ 5 | font-family: monospace; 6 | height: 300px; 7 | color: black; 8 | } 9 | 10 | /* PADDING */ 11 | 12 | .CodeMirror-lines { 13 | padding: 4px 0; /* Vertical padding around content */ 14 | } 15 | .CodeMirror pre { 16 | padding: 0 4px; /* Horizontal padding of content */ 17 | } 18 | 19 | .CodeMirror-scrollbar-filler, .CodeMirror-gutter-filler { 20 | background-color: white; /* The little square between H and V scrollbars */ 21 | } 22 | 23 | /* GUTTER */ 24 | 25 | .CodeMirror-gutters { 26 | border-right: 1px solid #ddd; 27 | background-color: #f7f7f7; 28 | white-space: nowrap; 29 | } 30 | .CodeMirror-linenumbers {} 31 | .CodeMirror-linenumber { 32 | padding: 0 3px 0 5px; 33 | min-width: 20px; 34 | text-align: right; 35 | color: #999; 36 | white-space: nowrap; 37 | } 38 | 39 | .CodeMirror-guttermarker { color: black; } 40 | .CodeMirror-guttermarker-subtle { color: #999; } 41 | 42 | /* CURSOR */ 43 | 44 | .CodeMirror-cursor { 45 | border-left: 1px solid black; 46 | border-right: none; 47 | width: 0; 48 | } 49 | /* Shown when moving in bi-directional text */ 50 | .CodeMirror div.CodeMirror-secondarycursor { 51 | border-left: 1px solid silver; 52 | } 53 | .cm-fat-cursor .CodeMirror-cursor { 54 | width: auto; 55 | border: 0 !important; 56 | background: #7e7; 57 | } 58 | .cm-fat-cursor div.CodeMirror-cursors { 59 | z-index: 1; 60 | } 61 | 62 | .cm-animate-fat-cursor { 63 | width: auto; 64 | border: 0; 65 | -webkit-animation: blink 1.06s steps(1) infinite; 66 | -moz-animation: blink 1.06s steps(1) infinite; 67 | animation: blink 1.06s steps(1) infinite; 68 | background-color: #7e7; 69 | } 70 | @-moz-keyframes blink { 71 | 0% {} 72 | 50% { background-color: transparent; } 73 | 100% {} 74 | } 75 | @-webkit-keyframes blink { 76 | 0% {} 77 | 50% { background-color: transparent; } 78 | 100% {} 79 | } 80 | @keyframes blink { 81 | 0% {} 82 | 50% { background-color: transparent; } 83 | 100% {} 84 | } 85 | 86 | /* Can style cursor different in overwrite (non-insert) mode */ 87 | .CodeMirror-overwrite .CodeMirror-cursor {} 88 | 89 | .cm-tab { display: inline-block; text-decoration: inherit; } 90 | 91 | .CodeMirror-rulers { 92 | position: absolute; 93 | left: 0; right: 0; top: -50px; bottom: -20px; 94 | overflow: hidden; 95 | } 96 | .CodeMirror-ruler { 97 | border-left: 1px solid #ccc; 98 | top: 0; bottom: 0; 99 | position: absolute; 100 | } 101 | 102 | /* DEFAULT THEME */ 103 | 104 | .cm-s-default .cm-header {color: blue;} 105 | .cm-s-default .cm-quote {color: #090;} 106 | .cm-negative {color: #d44;} 107 | .cm-positive {color: #292;} 108 | .cm-header, .cm-strong {font-weight: bold;} 109 | .cm-em {font-style: italic;} 110 | .cm-link {text-decoration: underline;} 111 | .cm-strikethrough {text-decoration: line-through;} 112 | 113 | .cm-s-default .cm-keyword {color: #708;} 114 | .cm-s-default .cm-atom {color: #219;} 115 | .cm-s-default .cm-number {color: #164;} 116 | .cm-s-default .cm-def {color: #00f;} 117 | .cm-s-default .cm-variable, 118 | .cm-s-default .cm-punctuation, 119 | .cm-s-default .cm-property, 120 | .cm-s-default .cm-operator {} 121 | .cm-s-default .cm-variable-2 {color: #05a;} 122 | .cm-s-default .cm-variable-3 {color: #085;} 123 | .cm-s-default .cm-comment {color: #a50;} 124 | .cm-s-default .cm-string {color: #a11;} 125 | .cm-s-default .cm-string-2 {color: #f50;} 126 | .cm-s-default .cm-meta {color: #555;} 127 | .cm-s-default .cm-qualifier {color: #555;} 128 | .cm-s-default .cm-builtin {color: #30a;} 129 | .cm-s-default .cm-bracket {color: #997;} 130 | .cm-s-default .cm-tag {color: #170;} 131 | .cm-s-default .cm-attribute {color: #00c;} 132 | .cm-s-default .cm-hr {color: #999;} 133 | .cm-s-default .cm-link {color: #00c;} 134 | 135 | .cm-s-default .cm-error {color: #f00;} 136 | .cm-invalidchar {color: #f00;} 137 | 138 | .CodeMirror-composing { border-bottom: 2px solid; } 139 | 140 | /* Default styles for common addons */ 141 | 142 | div.CodeMirror span.CodeMirror-matchingbracket {color: #0f0;} 143 | div.CodeMirror span.CodeMirror-nonmatchingbracket {color: #f22;} 144 | .CodeMirror-matchingtag { background: rgba(255, 150, 0, .3); } 145 | .CodeMirror-activeline-background {background: #e8f2ff;} 146 | 147 | /* STOP */ 148 | 149 | /* The rest of this file contains styles related to the mechanics of 150 | the editor.
