使用 Markdown 记录日志一个用于生成 Markdown 格式的日志文件的开源

[](https://ci.appveyor.com/project/Wheelies/markdownlog) Markdown is a great format for representing an application's internal data structures for debugging and diagnostic purposes. It is a flexible format that is readable in its raw form yet capable of being transformed into HTML for documentation or reporting. MarkdownLog can produce all features described in John Gruber's [original spec](http://daringfireball.net/projects/markdown/) from common .NET types. Tables ------ This is how a table is built from a List of objects: var data = new[] { new{Year = 1991, Album = "Out of Time", Songs=11, Rating = "* * * *"}, new{Year = 1992, Album = "Automatic for the People", Songs=12, Rating = "* * * * *"}, new{Year = 1994, Album = "Monster", Songs=12, Rating = "* * *"} }; Console.Write(data.ToMarkdownTable()); // Produces: // // Year | Album | Songs | Rating // ----:| ------------------------ | -----:| --------- // 1991 | Out of Time | 11 | * * * * // 1992 | Automatic for the People | 12 | * * * * * // 1994 | Monster | 12 | * * * Once passed through a GitHub-flavoured parser, you get a HTML table, complete with headings and alignments: Year | Album | Songs | Rating ----:| ------------------------ | -----:| --------- 1991 | Out of Time | 11 | * * * * 1992 | Automatic for the People | 12 | * * * * * 1994 | Monster | 12 | * * * Lists ----- A collection can be output as a numbered list: var planets = new[] { "Mercury", "Venus", "Earth", "Mars", "Jupiter", "Saturn", "Uranus", "Neptune"}; Console.Write(planets.ToMarkdownNumberedList()); // Produces: // // 1. Mercury // 2. Venus // 3. Earth // 4. Mars // 5. Jupiter // 6. Saturn // 7. Uranus // 8. Neptune When passed through a Markdown parser, this becomes: 1. Mercury 2. Venus 3. Earth 4. Mars 5. Jupiter 6. Saturn 7. Uranus 8. Neptune Alternatively, the list can have bullets: var beatles = new[] { "John", "Paul", "Ringo", "George" }; Console.Write(beatles.ToMarkdownBulettedList()); //Produces: // // * John // * Paul // * Ringo // * George This is parsed to: * John * Paul * Ringo * George Bar Chart example ---------------- A barchart can be produced from a collection of KeyValue or Tuple objects var worldCup = new Dictionary<string, int> { {"Brazil", 5}, {"Italy", 4}, {"Germany", 4}, {"Argentina", 2}, {"Uruguay", 2}, {"France", 1}, {"Spain", 1}, {"England", 1} }; Console.Write(worldCup.ToMarkdownBarChart()); // Produces: // // Brazil |##### 5 // Italy |#### 4 // Germany |#### 4 // Argentina |## 2 // Uruguay |## 2 // France |# 1 // Spain |# 1 // England |# 1 // ------ Bar charts are not supported by standard Markdown. When a barchart is passed through a Markdown parser, it is rendered as a code block that retains its structure: Brazil |##### 5 Italy |#### 4 Germany |#### 4 Argentina |## 2 Uruguay |## 2 France |# 1 Spain |# 1 England |# 1 ------ A bar chart can be produced from floating point and negative numbers and scaling can be applied as desired: const int valueCount = 20; var chart = new BarChart { ScaleAlways = true, MaximumChartWidth = 40, DataPoints = from i in Enumerable.Range(0, valueCount) let rad = (i * 2.0 * Math.PI) / valueCount select new BarChartDataPoint { CategoryName = string.Format("Cos({0:0.0})", rad), Value = Math.Cos(rad) } }; This produces: Cos(0.0) |#################### 1 Cos(0.3) |################### 0.95 Cos(0.6) |################ 0.81 Cos(0.9) |############ 0.59 Cos(1.3) |###### 0.31 Cos(1.6) | 0 Cos(1.9) ######| -0.31 Cos(2.2) ############| -0.59 Cos(2.5) ################| -0.81 Cos(2.8) ###################| -0.95 Cos(3.1) ####################| -1 Cos(3.5) ###################| -0.95 Cos(3.8) ################| -0.81 Cos(4.1) ############| -0.59 Cos(4.4) ######| -0.31 Cos(4.7) | 0 Cos(5.0) |###### 0.31 Cos(5.3) |############ 0.59 Cos(5.7) |################ 0.81 Cos(6.0) |################### 0.95 ----------------------------------------- Paragraphs ---------- Strings can be written as a word-wrapped paragraph: var text ="Lolita, light of my life, fire of my loins. My sin, my soul. Lo-lee-ta: the tip of the tongue taking a trip of three steps down the palate to tap, at three, on the teeth. Lo. Lee. Ta."; Console.Write(text.ToMarkdownParagraph()); // Produces: // // Lolita, light of my life, fire of my loins. My sin, my soul. Lo-lee-ta: the tip // of the tongue taking a trip of three steps down the palate to tap, at three, on // the teeth. Lo. Lee. Ta. After parsing, this becomes: Lolita, light of my life, fire of my loins. My sin, my soul. Lo-lee-ta: the tip of the tongue taking a trip of three steps down the palate to tap, at three, on the teeth. Lo. Lee.
