+[UCG](https://crates.io/crates/ucg) is a universal grammar for configuration. It's goal is not to define a configuration format
+like JSON, YAML, or TOML. It is not intended to replace the other configuration formats. Instead
+it is intended to provide a common grammar for generating those formats. Currently UCG is able to
+generate conversions for the following formats.
+
+* Environment Variables
+* Command Line Flags
+* An executable shell launch script combining the two above
+* JSON
+* YAML
+* TOML
+
+UCG allows you to use one common grammar to generate configuation values for any applications that
+use one of provided conversion outputs while also allowing you to easily share common configuration
+values like hostnames, jvm settings, and database settings.
+
+UCG can build an entire directory of files or a single file.

+Installing
+----------
+
+### Cargo
+
+You can install ucg using Rust's Cargo package manager.
+
+```sh
+cargo install ucg
+```
+
+### Compiling
+
+You can also install from source yourself. First ensure that you have the latest
+version of Rust installed. You can find install instructions for Rust
+[here](https://www.rust-lang.org/en-US/install.html). Then you can get the source
+from github and use cargo to build.
+
+```sh
+# Get the source code from github
+git clone https://github.com/zaphar/ucg
+cd ucg
+# optionally checkout the current version
+git checkout v0.2.3
+# use cargo to build and install
+cargo install --path .
+```
+
+A simple configuration
+----------------------
+
+To create a configuration and build it in ucg you must first create a ucg file. Copy the below contents into a file called `sample.ucg`. All ucg files must end in the ucg
+extension.
+
+```
+let hostname = "www.example.com";
+let mysql_host = "localhost";
+let mysql_port = 3306;
+
+let config = {
+    // This uses a format string to put the hostname into
+    // the baseUrl.
+    baseUrl = "http://@" % (hostname),
+    db = {
+        host = mysql_host,
+        port = myssql_port,
+    },
+}
+
+// Generate a yaml file from that config.
+out yaml config;
+```
+
+The above binds 3 values to names and then creates a config tuple using those values.
+We'll look in more detail at ucg's syntax later.
+
+To generate a yaml file from the above run the ucg build command.
+
+```sh
+ucg build sample.ucg
+cat sample.yaml
+```
+
+Ucg will generate the yaml file with the same name as the file containing the out statement.
+
+The ucg command line
+-----------
+
+Ucg has builtin help on the command line. You can 
+
+    $> ucg help
+    ucg 0.2.2
+    Jeremy Wall <jeremy@marzhillstudios.com>
+    Universal Configuration Grammar compiler.
+

+        ucg [SUBCOMMAND]
+    
+    FLAGS:
+        -h, --help       Prints help information

+An Overview
+-----------
+
+UCG is a language specialized for generating configurations. It does not have classes,
+inheritance,  closures, or a full type system. All values are immutable once bound to
+a name. A valid UCG file is composed of a series of statements. Statements can be
+an expression, introduce named bindings, or create different outputs. All statements
+must be terminiated by a semicolon.
+
+Some words are reserved in ucg and can not be used as a named binding.
+

+* assert
+* true

+Ucg expressions can reference a bound name, do math, concatenate lists or strings, 
+copy and modify a struct, or format a string.
+
+Symbols
+-------
+
+Many ucg expressions or statements use a symbol. A symbol might be used for either 
+name for a binding or a name for a field. Symbols must start with an ascii letter and can contain any ascii letter, number, `_`, or `-` characters.
+
+Selectors
+------
+
+A UCG selector references a bound value by name. They can descend into tuples or lists
+or refer to symbols in imported files. They are symbol followed optionally by a list
+of other symbols or numbers separated by a `.` to reference subfields or indexes in a list.
+
+You can reference a field in a tuple by putting the field name after a dot. Lists are always 0 indexed. You can index into a list by referencing the index after
+a `.`.
+
+```
+let tuple = {
+    inner = {
+        field = "value",
+    },
+    list = [1, 2, 3],
+};
+
+// reference the field in the inner tuple in our tuple defined above.
+tuple.inner.field;
+
+// reference the field in the list contained in our tuple defined above.
+tuple.list.0;
+```
+
+### The environment Selector
+
+There is a special selector in ucg for obtaining a value from the environment. The 
+`env` selector references the environment variables in environment at the time of
+the build. You reference environment variables just like it was a tuple. Attempting
+to reference a variable that doesn't exist will be a compile error.
+
+```
+let env_name = env.DEPLOY_ENV;
+```
+
+Binary Operators
+----------
+
+UCG has a numver of binary infix operators. Some work only on numeric values and others
+work on more than one type.
+
+### Numeric Operators
+
+ucg supports the following numeric operators, `+`, `-`, `*`, `/` Each one is type safe 
+and infers the types from the values they operate on. The operators expect both the 
+left and right operands to be of the same type.
+
+```
+1 + 1;
+1.0 - 1.0;
+```
+
+### Concatenation
+
+The `+` operator can also do concatenation on strings and lists. As with the numeric
+version both sides must be the same type, either string or list.
+
+```
+"Hello " + "World"; // "Hello World"
+[1, 2] + [3]; // [1, 2, 3]
+```
+
+### Comparison Operators
+
+UCG supports the comparison operators `==`, `!=`, `>=`, `<=`, `<`, and `>`. The all
+expect both sides to be of the same type.
+
+The `>`, `<`, `>=`, and `>=` operators are only supported on numeric types (i.e. int, 
+and float).
+
+```
+1 > 2; // result is false
+2 < 3; // result is true
+10 > "9"; // This is a compile error.
+(1+2) == 3;
+```
+
+The equality operators `==` and `!=` are supported for all types and will perform deep 
+equal comparisons on complex types.
+
+```
+let tpl1 = {
+  foo = "bar",
+  one = 1
+};
+let tpl2 = {
+  foo = "bar",
+  one = 1
+};
+tpl1 == tpl2; // returns true
+let tpl2 = {
+  foo = "bar",
+  one = 1
+  duck = "quack",
+};
+tpl1 == tpl3; // returns false
+```
+
+Because tuples are an ordered set both tuples in a comparison must have their fields in
+the same order to compare as equal.
+
+#### Operator Precedence
+
+UCG binary operators follow the typical operator precedence for math. `*` and `/` are 
+higher precendence than `+` and `-` which are higher precedence than any of the 
+comparison operators.
+
+Copy Expressions
+----------------
+
+UCG expressions have a special copy expression for tuples. These faciliate a form of
+data reuse as well as a way to get a modified version of a tuple. Copy expressions
+start with a selector referencing a tuple followed by braces `{}` with `name = value`
+pairs separated by commas. Trailing commas are allowed.
+
+Copied expressions can change base fields in the copied tuple or add new fields. If 
+you are changing the value of a base field in the copy then the new value must be of 
+the same type as the base field's value. This allows you to define a base "type" of
+sorts and ensure that any modified fields stay the same.
+
+```
+let base = {
+    field1 = "value1",
+    field2 = 100,
+    field3 = 5.6,
+};
+
+let overridden = base{
+    field1 = "new value"
+};
+
+let expanded = base{
+    field2 = 200,
+    field3 = "look ma a new field",
+};
+
+let bad = base{
+    field1 = 300, // Error!!! must be a string.
+};
+
+```
+
+There is a special selector that can be used in a copy expression to refer to the base 
+tuple in a copy called `self`. `self` can only be used in the body of the copy.
+
+```
+let nestedtpl = {
+    field1 = "value1",
+    inner = {
+        field2 = 2
+        inner = {
+            field3 = "three",
+        },
+    },
+};
+
+let copiedtpl = nestedtpl{
+    inner = self.inner{
+        inner = self.inner{
+            field4 = 4,
+        },
+    },
+};
+```
+
+Format Expressions
+----------
+
+UCG has a format expression that has a limited form of string templating. A format 
+expression starts with a string followed by the `%` operator and a list of arguments 
+in parentheses separated by commas. Trailing commas are allowed. The format string
+should have `@` in each location where a value should be placed. Any primitive value
+can be used as an argument.
+
+```
+"https://@:@/" % (host, port)
+```
+
+Conditionals
+----------
+
+UCG supports a limited conditional expression called a select. A select expression 
+starts with the `select` keyword and is followed by a an expression resolving to a 
+string naming the field to select, an expression resolving to the default value, and 
+finally a tuple literal to select the field from. If the field selected is not in the 
+tuple then the default value will be used.
+
+```
+let want = "baz";
+
+//     field  default
+select want, "quux", {
+    baz = "foo",
+    fuzz = "bang",
+}; // result will be "foo"
+
+//     field    default
+select "quack", "quux", {
+    baz = "foo",
+    fuzz = "bang",
+}; // result will be "quux"
+```
+
+Macros
+-----
+
+Macros look like functions but they are resolved at compile time and configurations 
+don't execute so they never appear in output. Macros do not close over their 
+environment so they can only reference values defined in their arguments. They can't 
+refer to bindings or other macros defined elsewhere. They are useful for constructing 
+tuples of a certain shape or otherwise promoting data reuse. You define a macro with 
+the `macro` keyword followed by the arguments in parentheses, a `=>`, and then a tuple
+literal.
+
+```
+let mymacro = macro (arg1, arg2) => {
+    host = arg1,
+    port = arg2,
+    connstr = "couchdb://@:@" % (arg1, arg2),
+}
+
+let my_dbconf = mymacro("couchdb.example.org", "9090");
+
+let my_dbhost = dbconf.host;
+```

+Expression Statements
+-------
+
+The simplest and least useful is the expression statement. It is any valid expression 
+followed by a semicolon.
+
+```
+1;
+4 / 2;
+"foo";
+"foo" + "bar";
+```
+
+Despite the fact that these are valid the results are thrown away and can essentially 
+be considered a noop. If we ever create a repl for ucg statements they may prove more 
+useful.
+
+Named Value Statements
+--------
+
+### Let statements
+
+There are two statements that can introduce a named value for a given ucg file. Let 
+statnements and import statements. Any collisions in binding names inside a file are 
+treated as compile errors. Bindings are immutable and once bound they can't be 
+modified.
+
+```
+let name = "foo";
+```
+
+### Import Statement
+
+The import statement imports the contents of another ucg file into the current file 
+with a name. The imported files named values are exposed as a tuple in the referencing 
+file. It starts with the `import` keyword and is followed by a quoted path to the ucg 
+file, the keyword `as`, and a name for the imported values.
+
+```
+import "dbconfigs.ucg" as dbconfigs;
+let mysqlconf = dbconfigs.mysql;
+```
+
+Output Statements
+-----------
+
+Some statements in ucg exist to generate an output. Either a compiled configuration or the results of test assertions.
+
+### Assert Statements
+
+The assert statement defines an expression that must evaluate to either true or false. 
+Assert statements are noops except during a validation compile. They give you a way to 
+assert certains properties about your data and can be used as a form of unit testing 
+for your configurations. It starts with the `assert` keyword followed by a valid block 
+of ucg statements delimited by `|` characters. The final statement in the in the block 
+must evaluate to a boolean expression.
+
+```
+assert |
+    host == "www.example.com";
+|;
+
+assert |
+    select qa, 443, {
+      qa = 80,
+      prod = 443,
+    } == 443;
+|;
+```
+
+When _test.ucg files are run in a test run then ucg will output a log of all the assertions to stdout. Giving you a simple test harness for your ucg configs.
+
+### Out Statements
+
+The Out statement defines the output for a UCG file. It identifies the output 
+converter type and an expression that will be output. The output converter type is 
+expected to be one of the registered converters (e.g. json, exec) and the artifact 
+file will take the same name as the ucg file with the extension replaced by the 
+defined extension for that converter.
+
+For a file named api_config.ucg with the following contents:
+
+```
+let myconf = {
+    api_url = "https://example.org/api/v1/",
+    api_token = env.API_TOKEN,
+};
+out json myconf;
+```
+
+ucg will output the myconf tuple as json to a file called api_config.json

+Primitive Values
+-------------
+
+UCG has a few primitive types.
+
+### Boolean
+
+Boolean types can be either `true` or `false`. They are represented by symbols of the
+same name.
+
+```
+true;
+false;
+```
+
+### Integer
+
+An Integer is any 64 bit integer number.
+
+```
+1;
+```
+
+### Float
+
+A Float is any 64 bit floating point numer. You indicate a number is a Float by
+including a decimal point. Any number with a decimal point is a float.
+
+```
+1.0;
+.0;
+1.;
+```
+
+### String
+
+Strings are any double quoted text.
+
+```
+"This is a string";
+```
+
+### NULL or the Empty type
+
+NULL is the empty type. It represents the absence of a value. It is represented by the
+symbol `NULL`.
+
+```
+let empty = NULL;
+```
+
+Complex types
+-----------
+
+UCG also has two complex types.
+
+### Tuples
+
+Tuples are an ordered set of name value pairs. They are delimited by braces and should
+contain 1 or more `name = expression` pairs separated by commas. Trailing commas are allowed.
+
+```
+let tuple = {
+    field = "value",
+    inner = {
+        number = 1,
+    },
+};
+```
+
+### Lists
+
+Lists are a 0 indexed heterogenous list of expressions. The are delimited by square 
+brackets and should contain 1 or more expressions separated by commas. Trailing commas 
+are allowed.
+
+```
+let list = [1, "two", {three = 3},];

+# book
+
+A theme based on [Gitbook](https://www.gitbook.com), to write documentation
+or books.
+
+![book screenshot](https://github.com/Keats/book/blob/master/screenshot.png?raw=true)
+
+
+## Contents
+
+- [Installation](#installation)
+- [Options](#options)
+  - [Numbered chapters](#numbered-chapters)
+
+## Installation
+First download this theme to your `themes` directory:
+
+```bash
+$ cd themes
+$ git clone https://github.com/Keats/book.git
+```
+and then enable it in your `config.toml`:
+
+```toml
+theme = "book"
+# Optional, if you want search
+build_search_index = true
+```
+
+## Usage
+Book will generate a book from the files you place in the `content` directory.  Your book
+can have two levels of hierarchy: chapters and subchapters.
+
+Each chapter should be a `section` within the Gutenberg site and should have an `_index.md`
+file that sets its `weight` front-matter variable to its chapter number.  For example,
+chapter 2 should have `weight = 2`.  Additionally, each chapter should also set the
+`sort_by = "weight"` in its front matter.
+
+Each subchapter should be a `page` and should have its `weight` variable set to the subchapter
+number.  For example, subchapter 3.4 should have `weight = 4`.
+
+Finally, you should create an `_index.md` file and set the `redirect_to` front-matter variable
+to redirect to the first section of your content.  For example, if your first section has the
+slug `introduction`, then you would set `redirect_to = "introduction"`.
+
+## Options
+
+### Numbered chapters
+By default, the `book` theme will number the chapters and pages in the left menu.
+You can disable that by setting the `book_numbered_chapters` in `extra`:
+
+```toml
+book_numbered_chapters = false
+```

+Pages and sections are actually very similar.
+
+## Page variables
+Gutenberg will try to load the `templates/page.html` template, the `page.html` template of the theme if one is used
+or will render the built-in template: a blank page.
+
+Whichever template you decide to render, you will get a `page` variable in your template
+with the following fields:
+
+
+```ts
+content: String;
+title: String?;
+description: String?;
+date: String?;
+slug: String;
+path: String;
+permalink: String;
+summary: String?;
+tags: Array<String>;
+category: String?;
+extra: HashMap<String, Any>;
+// Naive word count, will not work for languages without whitespace
+word_count: Number;
+// Based on https://help.medium.com/hc/en-us/articles/214991667-Read-time
+reading_time: Number;
+// `previous` and `next` are only filled if the content can be sorted
+previous: Page?;
+next: Page?;
+// See the Table of contents section below for more details
+toc: Array<Header>;
+```
+
+## Section variables
+By default, Gutenberg will try to load `templates/section.html`. If there isn't
+one, it will render the built-in template: a blank page.
+
+Whichever template you decide to render, you will get a `section` variable in your template
+with the following fields:
+
+
+```ts
+content: String;
+title: String?;
+description: String?;
+date: String?;
+slug: String;
+path: String;
+permalink: String;
+extra: HashMap<String, Any>;
+// Pages directly in this section, sorted if asked
+pages: Array<Pages>;
+// Direct subsections to this section, sorted by subsections weight
+subsections: Array<Section>;
+// Naive word count, will not work for languages without whitespace
+word_count: Number;
+// Based on https://help.medium.com/hc/en-us/articles/214991667-Read-time
+reading_time: Number;
+// See the Table of contents section below for more details
+toc: Array<Header>;
+```
+
+## Table of contents
+
+Both page and section have a `toc` field which corresponds to an array of `Header`.
+A `Header` has the following fields:
+
+```ts
+// The hX level
+level: 1 | 2 | 3 | 4 | 5 | 6;
+// The generated slug id
+id: String;
+// The text of the header
+title: String;
+// A link pointing directly to the header, using the inserted anchor
+permalink: String;
+// All lower level headers below this header
+children: Array<Header>;
+```
