Coddoc

Description



coddoc is a jsdoc parsing library. Coddoc is different in that it is easily extensible by allowing users to
add tag and code parsers through the use of coddoc.addTagHandler and coddoc.addCodeHandler.
coddoc also parses source code to be used in APIs.


Coddoc also supports the generation of markdown and html through the use of different templates. Currently
the templates use Handlebars but you may use any templating engine
you wish


JSDOC Tags



JSDoc tags currently supported are:



  • augments|extends : extend an object

  • lends : document all members of an anonymous object as members of a declared symbol

  • namespace : document a namespace

  • parameter|param|arg|argument : parameters of a function

  • return|returns : return value of a function

  • memberof|memberOf : explicitly document a cod block as a member of an object

  • name : explicitly document the name of a symbol

  • constructor|constructs : document a symbol as a constructor for a class

  • class : documents a symbol as a class

  • classdesc : alternate way to add a description to a class

  • example : document an example/s of a symbol

  • private : document a symbol as private.

  • ignore : allows you to document a symbol but ignore it in parsing

  • method|function : explicily document a symbol as a method

  • field : explicily document a symbol as a field

  • type : document the type of a field

  • default : document the default value of a field

  • throws|throw|exception : document any exception thrown by a method

  • property : document a property in the constructor declaration of a class

  • borrows : document any filed/methods borrowed from a class

  • constant|const : document a field as a constant

  • desc|description : alternate way to explicitly document the description of a symbol

  • public:explicitly document a symbol as public

Coddoc Tags


Coddoc also has a few additional tags.

  • ignoreCode : ignore the parsed code in the output

  • includeDoc : include an external doc. External docs can be html or markdown.
    Example

    @includeDoc [Title Of Doc] ../location/of_doc.md


  • projectName : document the projectName

  • github : url to github project

  • code : specifies a code block without needing an example tag
    Example

    {@code var test = "test"; }

  • header : allows you to document a header that should appear before
    generated documentation

  • footer : allows you to document a footer that should come after the generated documentation

  • protected : allows you to document a field as protected

Installation


Locally

npm install coddoc

Globally


npm install -g coddoc

Usage


Down doc does not currently create multi file docs instead will output to a single file. You may however implement
your own formatter to create multiple files.

Command line options


  • -d --directory : the directory that contains your code

  • [-f --formatter] : optional formatter to use, if not specified then a JSON object of the symbols will
    be output

  • [-p --pattern] : optional file pattern to use when searching for files

Examples

JSON output


coddoc -d ./lib > symbols.json

To use the markdown formatter


coddoc -d ./lib -f markdown > README.md

To use the HTML formatter


coddoc -d ./lib -f html > index.html

To use pragmatically

var coddoc = require("coddoc");
var tree = coddoc.parse({directory : __dirname + "/lib"});
var classes = tree.classes, namespaces = tree.namespaces;
//do something

API




Defined index.js


Entry point for parsing code.

Example


var tree = coddoc({directory : path.resolve(__dirname + "lib")});

//To use markdown formatter
var doc = coddoc({directory : path.resolve(__dirname + "lib"), formatter : coddoc.formatters.markdown});

//To use html formatter
var doc = coddoc({directory : path.resolve(__dirname + "lib"), formatter : coddoc.formatters.html});

//To use custom file pattern
var doc = coddoc({directory : path.resolve(__dirname + "lib"), patter : /.+\.test\.js$/i, formatter : coddoc.html});

Arguments



  • options : options object.


  • options.dir String : the directory of code to parse.


  • [options.pattern= /.+\.js$/i] RegExp : a regular expression to test files agains


  • options.formatter? Object : And optional formatter to format the tree. The object must contain
    a generate method. See coddoc.formatters.html



Source


function (options){
options = options || {};
var baseDir = options.dir, filePattern = options.pattern || FILE_PATTERN;
if (!baseDir) {
console.log("directory required");
}
var fileMap = {};
(function findFiles(dir) {
var files = fs.readdirSync(dir);
files.forEach(function (file) {
var filePath = path.resolve(dir, file);
var stat = fs.statSync(filePath);
if (stat.isDirectory()) {
findFiles(filePath);
} else if (stat.isFile() && filePattern.test(file)) {
fileMap[filePath] = fs.readFileSync(filePath, "utf8");
}
});
}(baseDir));
var context = new Context(), tree = new Tree();
Object.keys(fileMap).forEach(function (i, j) {
emitter.emit("file", i);
context.activateScope("global");
parser.parse(fileMap[i], path.relative(baseDir, i), tree, context, emitter);
});
return tree;

}





addCodeHandler

Static


Function



Public




Defined parser/code.js


Adds a handler for a particular code regular expression. Useful if you want to
match a specific type of code not handled by default. When inside of of the parse function
you can use the RegExp.$ properties to access match sub expressions.

By Default code blocks of the following form are parsed.



// /^function (\w+) *\{/
function(){}

// /^var *(\w+) *= *function/
var x = function(){};

// /^(\w+(?:\.\w+)*)\.prototype\.(\w+(?:\.\w+)?) *= *function/
MyObject.prototype.testFunction = function(){};

// /^(\w+(?:\.\w+)*)\.prototype\.(\w+(?:\.\w+)?) *= *([^\n;]+)/
MyObject.prototype.testProperty = "property";

// /^(\w+(?:\.\w+)+) *= *function/
some.object.testFunction = function(){}

// /^(\w+(?:\.\w+)+) *= *([^\n;]+)/
some.object.testFunction = ["some", "property"];

// /^var +(\w+) *= *([^\n;]+)/
var testProperty = {my : "property"};

var myObject = {
// /^\"?(\w+)\"? *\: *function/
testFunction : function(){},

// /^\"?(\w+)\"? *\: *([^,\n]+)/
testProperty : "some property"
}

Example


var util = require("coddoc").util;
//parse code in the format of var myLocal = name.space.myFunction = function(){};
//give it a high priority to allow it to override current handlers.
addHandler(/^var *\w+ *= * (\w+(?:\.\w+)*) = *function/, 20, function (str, symbol, context) {
var splitName = util.splitName(RegExp.$1), name = splitName.name, activeScope = splitName.memberof, params = util.getParamList(str);
return {
type:'function',
isFunction:true,
memberof:activeScope,
isStatic:activeScope ? !activeScope.match(".prototype") : false,
isPrivate:name.match(/^_/) != null,
name:name,
params:params,
code:['function (', params.map(
function (n) {
return n.name.name;
}).join(","), '){\n ', util.getCode(str, "{").split("\n").join("\n "), "\n}"].join("")
};
});

Arguments



  • regexp : the regular expression used to match code blocks.


  • [priority= 0] : the priority to give this code handler if not provided
    it is defaulted to 0.


  • parse : a function that returns an object. The object will be set as the codeObject on the coddoc.Symbol. The properties of the object will be added to the coddoc.Symbol for processing later.



Source


function (regexp,priority,parse){
if (util.isFunction(priority)) {
parse = priority;
priority = 0;
}
handlers.push({
priority:priority,
match:function (str) {
return regexp.exec(str);
},
parse:parse
});
handlers.sort(sortHandlers);

}




addTagHandler

Static


Function



Public




Defined parser/tags.js


Adds a new tag to be parsed. You can use this to add custom tags. coddoc will
not do anything with the new tag by default, however you can add functionality to handle the
new tag in the template.

Example


//if a tag is contains a '|' character then each variation will resolve the the same parser function.
coddoc.addTagHandler("void|VOID|Void", function(comment, symbol, context){
//do something with the tag or add properties to the symbol.
symbol.isVoid = true;
symbol.tags.push({tag : "void", props : {}});
});
//in the template you can add functionality to handle the new tag. For example:
//in the html symbol.tmpl you could add a new label to the name header
<h3>
{{name}}
{{#if isStatic}}
<span class="label label-info">Static</span>
{{/if}}
{{#if isFunction}}
<span class="label label-label">Function</span>
{{/if}}
{{#if isPrivate}}
<span class="label label-important">Private</span>
{{else}}
{{#if isProtected}}
<span class="label label-warning">Protected</span>
{{else}}
<span class="label label-success">Public</span>
{{/if}}
{{/if}}
{{#if isVoid}}
<span class="label label-label">Void</span>
{{/if}}
</h3>

Arguments



  • tag : the tag to parse, if a tag is contains a '|' character then the string will be split and each variation will resolve to the same parse function. If the tag already exists then the old implementation will be replaced by the new one.


  • parse : a parser function to invoke when a tag that matches the name is encountered.



Source


function (tag,parse){
tag.split("|").forEach(function (tag) {
tags[tag] = {
parse:parse || function () {
return {tag:tag, props:{}};
}};
});

}

var endCIndex = str.indexOf("*/", i);
if (endCIndex !== -1) {
comment = str.substr(startCIndex + 2, endCIndex - (startCIndex + 2)).split("\n").map(joinAndReplace).join("\n");
emitter.emit("comment", comment);
i = endCIndex + 1;
//console.log(str.substr(startCIndex, endCIndex - startCIndex));
//console.log(comment);
var res = parseTags({comment:comment, start:startCIndex, end:endCIndex + 2}, str, filepath, context),

Static


Function



Protected




Defined parser/code.js


Uses Registered handlers to parse the next block of code from a code fragment. This function is
used by coddoc.parse to parse code for comments.

Arguments



  • str : the source string to parse


  • symbol : the symbol to add parsed properties from.


  • context : the current context



Source


function (str,symbol,context){
var l = handlers.length, ret = {};
for (var i = 0; i < l; i++) {
var h = handlers[i];
if (h.match(str)) {
ret = h.parse(str, symbol, context);
break;
}
}
if (ret) {
symbol.codeObject = ret;
Object.keys(ret).forEach(function (i) {

});
}

}




parseTag

Static


Function



Protected




Defined parser/tags.js


Parses a tag and the coresponding comment using a matching tag handler. Each parsed tag
could add a new property to the coddoc.Symbol. The parsed tag will be added the the
coddoc.Symbol#tags array.

Example


coddoc.parseTag("someTag", "@someTag props...", sym, src, index, context);
//would add a new tag to the symbols property
{
tag : "tagname",
props : {...}
}

//the props value would also be added to the symbols params array.

Arguments



  • comment : the comment fragment being parsed


  • sym : the symbol that the comment corresponds to. The code object and values will have already been set.


  • context : the currect context object. The context allows tags to set new scopes and namespaces.


  • tag String : the tag name being parsed from the comment



Source


function (comment,sym,context){
var tag = comment.match(TAG_REGEXP), ret = {};
if (tag && tag.length === 2) {
