A website dedicated to the poetry of financial disaster~
-## Install
+## Installation
+
+### Install & Setup
First up, `virtualenv`:
pip install -e .
+Now that we've got all the deps, we'll want to create the database.
+
+ >>> from crisishaiku import app, db, User
+ >>> db.create_all()
+
+You'll see it blorp out some SQL. Let's make sure it worked.
+
+ >>> u = User('leigh', 'trouble@crisishaiku.com')
+ >>> db.session.add(u)
+ >>> db.session.commit()
+
+Yet more SQL, and hopefully no error message. Hooray!
+
+Finally, run the server:
+
+ bin/server
+
+And point your browser at http://localhost:5000/ -- you should see the request
+blow by. Hello, world!
+
+Oh, and finally: as a convenience, `bin/server` will attempt to activate the
+virtualenv if one isn't already active (as obviously I find that obnoxious
+and always forget).

+
+
+ This file creates a global JSON object containing two methods: stringify
+ and parse.
+
+ JSON.stringify(value, replacer, space)
+ value any JavaScript value, usually an object or array.
+
+ replacer an optional parameter that determines how object
+ values are stringified for objects. It can be a
+ function or an array of strings.
+
+ space an optional parameter that specifies the indentation
+ of nested structures. If it is omitted, the text will
+ be packed without extra whitespace. If it is a number,
+ it will specify the number of spaces to indent at each
+ level. If it is a string (such as '\t' or ' '),
+ it contains the characters used to indent at each level.
+
+ This method produces a JSON text from a JavaScript value.
+
+ When an object value is found, if the object contains a toJSON
+ method, its toJSON method will be called and the result will be
+ stringified. A toJSON method does not serialize: it returns the
+ value represented by the name/value pair that should be serialized,
+ or undefined if nothing should be serialized. The toJSON method
+ will be passed the key associated with the value, and this will be
+ bound to the value
+
+ For example, this would serialize Dates as ISO strings.
+
+ Date.prototype.toJSON = function (key) {
+ function f(n) {
+ // Format integers to have at least two digits.
+ return n < 10 ? '0' + n : n;
+ }
+
+ return this.getUTCFullYear() + '-' +
+ f(this.getUTCMonth() + 1) + '-' +
+ f(this.getUTCDate()) + 'T' +
+ f(this.getUTCHours()) + ':' +
+ f(this.getUTCMinutes()) + ':' +
+ f(this.getUTCSeconds()) + 'Z';
+ };
+
+ You can provide an optional replacer method. It will be passed the
+ key and value of each member, with this bound to the containing
+ object. The value that is returned from your method will be
+ serialized. If your method returns undefined, then the member will
+ be excluded from the serialization.
+
+ If the replacer parameter is an array of strings, then it will be
+ used to select the members to be serialized. It filters the results
+ such that only members with keys listed in the replacer array are
+ stringified.
+
+ Values that do not have JSON representations, such as undefined or
+ functions, will not be serialized. Such values in objects will be
+ dropped; in arrays they will be replaced with null. You can use
+ a replacer function to replace those with JSON values.
+ JSON.stringify(undefined) returns undefined.
+
+ The optional space parameter produces a stringification of the
+ value that is filled with line breaks and indentation to make it
+ easier to read.
+
+ If the space parameter is a non-empty string, then that string will
+ be used for indentation. If the space parameter is a number, then
+ the indentation will be that many spaces.
+
+ Example:
+
+ text = JSON.stringify(['e', {pluribus: 'unum'}]);
+ // text is '["e",{"pluribus":"unum"}]'
+
+
+ text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
+ // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
+
+ text = JSON.stringify([new Date()], function (key, value) {
+ return this[key] instanceof Date ?
+ 'Date(' + this[key] + ')' : value;
+ });
+ // text is '["Date(---current time---)"]'
+
+
+ JSON.parse(text, reviver)
+ This method parses a JSON text to produce an object or array.
+ It can throw a SyntaxError exception.
+
+ The optional reviver parameter is a function that can filter and
+ transform the results. It receives each of the keys and values,
+ and its return value is used instead of the original value.
+ If it returns what it received, then the structure is not modified.
+ If it returns undefined then the member is deleted.
+
+ Example:
+
+ // Parse the text. Values that look like ISO date strings will
+ // be converted to Date objects.
+
+ myData = JSON.parse(text, function (key, value) {
+ var a;
+ if (typeof value === 'string') {
+ a =
+/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
+ if (a) {
+ return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
+ +a[5], +a[6]));
+ }
+ }
+ return value;
+ });
+
+ myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
+ var d;
+ if (typeof value === 'string' &&
+ value.slice(0, 5) === 'Date(' &&
+ value.slice(-1) === ')') {
+ d = new Date(value.slice(5, -1));
+ if (d) {
+ return d;
+ }
+ }
+ return value;
+ });

+
+
+ This file creates a global JSON object containing two methods: stringify
+ and parse.
+
+ JSON.stringify(value, replacer, space)
+ value any JavaScript value, usually an object or array.
+
+ replacer an optional parameter that determines how object
+ values are stringified for objects. It can be a
+ function or an array of strings.
+
+ space an optional parameter that specifies the indentation
+ of nested structures. If it is omitted, the text will
+ be packed without extra whitespace. If it is a number,
+ it will specify the number of spaces to indent at each
+ level. If it is a string (such as '\t' or ' '),
+ it contains the characters used to indent at each level.
+
+ This method produces a JSON text from a JavaScript value.
+
+ When an object value is found, if the object contains a toJSON
+ method, its toJSON method will be called and the result will be
+ stringified. A toJSON method does not serialize: it returns the
+ value represented by the name/value pair that should be serialized,
+ or undefined if nothing should be serialized. The toJSON method
+ will be passed the key associated with the value, and this will be
+ bound to the value
+
+ For example, this would serialize Dates as ISO strings.
+
+ Date.prototype.toJSON = function (key) {
+ function f(n) {
+ // Format integers to have at least two digits.
+ return n < 10 ? '0' + n : n;
+ }
+
+ return this.getUTCFullYear() + '-' +
+ f(this.getUTCMonth() + 1) + '-' +
+ f(this.getUTCDate()) + 'T' +
+ f(this.getUTCHours()) + ':' +
+ f(this.getUTCMinutes()) + ':' +
+ f(this.getUTCSeconds()) + 'Z';
+ };
+
+ You can provide an optional replacer method. It will be passed the
+ key and value of each member, with this bound to the containing
+ object. The value that is returned from your method will be
+ serialized. If your method returns undefined, then the member will
+ be excluded from the serialization.
+
+ If the replacer parameter is an array of strings, then it will be
+ used to select the members to be serialized. It filters the results
+ such that only members with keys listed in the replacer array are
+ stringified.
+
+ Values that do not have JSON representations, such as undefined or
+ functions, will not be serialized. Such values in objects will be
+ dropped; in arrays they will be replaced with null. You can use
+ a replacer function to replace those with JSON values.
+ JSON.stringify(undefined) returns undefined.
+
+ The optional space parameter produces a stringification of the
+ value that is filled with line breaks and indentation to make it
+ easier to read.
+
+ If the space parameter is a non-empty string, then that string will
+ be used for indentation. If the space parameter is a number, then
+ the indentation will be that many spaces.
+
+ Example:
+
+ text = JSON.stringify(['e', {pluribus: 'unum'}]);
+ // text is '["e",{"pluribus":"unum"}]'
+
+
+ text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
+ // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
+
+ text = JSON.stringify([new Date()], function (key, value) {
+ return this[key] instanceof Date ?
+ 'Date(' + this[key] + ')' : value;
+ });
+ // text is '["Date(---current time---)"]'
+
+
+ JSON.parse(text, reviver)
+ This method parses a JSON text to produce an object or array.
+ It can throw a SyntaxError exception.
+
+ The optional reviver parameter is a function that can filter and
+ transform the results. It receives each of the keys and values,
+ and its return value is used instead of the original value.
+ If it returns what it received, then the structure is not modified.
+ If it returns undefined then the member is deleted.
+
+ Example:
+
+ // Parse the text. Values that look like ISO date strings will
+ // be converted to Date objects.
+
+ myData = JSON.parse(text, function (key, value) {
+ var a;
+ if (typeof value === 'string') {
+ a =
+/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
+ if (a) {
+ return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
+ +a[5], +a[6]));
+ }
+ }
+ return value;
+ });
+
+ myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
+ var d;
+ if (typeof value === 'string' &&
+ value.slice(0, 5) === 'Date(' &&
+ value.slice(-1) === ')') {
+ d = new Date(value.slice(5, -1));
+ if (d) {
+ return d;
+ }
+ }
+ return value;
+ });
