+# Squirrel - fluent SQL generator for Go
+
+```go
+import "github.com/Masterminds/squirrel"
+```
+
+
+[![GoDoc](https://godoc.org/github.com/Masterminds/squirrel?status.png)](https://godoc.org/github.com/Masterminds/squirrel)
+[![Build Status](https://api.travis-ci.org/Masterminds/squirrel.svg?branch=master)](https://travis-ci.org/Masterminds/squirrel)
+
+**Squirrel is not an ORM.** For an application of Squirrel, check out
+[structable, a table-struct mapper](https://github.com/Masterminds/structable)
+
+
+Squirrel helps you build SQL queries from composable parts:
+
+```go
+import sq "github.com/Masterminds/squirrel"
+
+users := sq.Select("*").From("users").Join("emails USING (email_id)")
+
+active := users.Where(sq.Eq{"deleted_at": nil})
+
+sql, args, err := active.ToSql()
+
+sql == "SELECT * FROM users JOIN emails USING (email_id) WHERE deleted_at IS NULL"
+```
+
+```go
+sql, args, err := sq.
+    Insert("users").Columns("name", "age").
+    Values("moe", 13).Values("larry", sq.Expr("? + 5", 12)).
+    ToSql()
+
+sql == "INSERT INTO users (name,age) VALUES (?,?),(?,? + 5)"
+```
+
+Squirrel can also execute queries directly:
+
+```go
+stooges := users.Where(sq.Eq{"username": []string{"moe", "larry", "curly", "shemp"}})
+three_stooges := stooges.Limit(3)
+rows, err := three_stooges.RunWith(db).Query()
+
+// Behaves like:
+rows, err := db.Query("SELECT * FROM users WHERE username IN (?,?,?,?) LIMIT 3",
+                      "moe", "larry", "curly", "shemp")
+```
+
+Squirrel makes conditional query building a breeze:
+
+```go
+if len(q) > 0 {
+    users = users.Where("name LIKE ?", fmt.Sprint("%", q, "%"))
+}
+```
+
+Squirrel wants to make your life easier:
+
+```go
+// StmtCache caches Prepared Stmts for you
+dbCache := sq.NewStmtCache(db)
+
+// StatementBuilder keeps your syntax neat
+mydb := sq.StatementBuilder.RunWith(dbCache)
+select_users := mydb.Select("*").From("users")
+```
+
+Squirrel loves PostgreSQL:
+
+```go
+psql := sq.StatementBuilder.PlaceholderFormat(sq.Dollar)
+
+// You use question marks for placeholders...
+sql, _, _ := psql.Select("*").From("elephants").Where("name IN (?,?)", "Dumbo", "Verna").ToSql()
+
+/// ...squirrel replaces them using PlaceholderFormat.
+sql == "SELECT * FROM elephants WHERE name IN ($1,$2)"
+
+
+/// You can retrieve id ...
+query := sq.Insert("nodes").
+    Columns("uuid", "type", "data").
+    Values(node.Uuid, node.Type, node.Data).
+    Suffix("RETURNING \"id\"").
+    RunWith(m.db).
+    PlaceholderFormat(sq.Dollar)
+
+query.QueryRow().Scan(&node.id)
+```
+
+You can escape question marks by inserting two question marks:
+
+```sql
+SELECT * FROM nodes WHERE meta->'format' ??| array[?,?]
+```
+
+will generate with the Dollar Placeholder:
+
+```sql
+SELECT * FROM nodes WHERE meta->'format' ?| array[$1,$2]
+```
+
+## FAQ
+
+* **How can I build an IN query on composite keys / tuples, e.g. `WHERE (col1, col2) IN ((1,2),(3,4))`? ([#104](https://github.com/Masterminds/squirrel/issues/104))**
+
+    Squirrel does not explicitly support tuples, but you can get the same effect with e.g.:
+
+    ```go
+    sq.Or{
+      sq.Eq{"col1": 1, "col2": 2},
+      sq.Eq{"col1": 3, "col2": 4}}
+    ```
+
+    ```sql
+    WHERE (col1 = 1 AND col2 = 2) OR (col1 = 3 AND col2 = 4)
+    ```
+
+    (which should produce the same query plan as the tuple version)
+
+* **Why doesn't `Eq{"mynumber": []uint8{1,2,3}}` turn into an `IN` query? ([#114](https://github.com/Masterminds/squirrel/issues/114))**
+
+    Values of type `[]byte` are handled specially by `database/sql`. In Go, [`byte` is just an alias of `uint8`](https://golang.org/pkg/builtin/#byte), so there is no way to distinguish `[]uint8` from `[]byte`.
+
+* **Some features are poorly documented!**
+
+    This isn't a frequent complaints section!
+
+* **Some features are poorly documented?**
+
+    Yes. The tests should be considered a part of the documentation; take a look at those for ideas on how to express more complex queries.

-/* This file defines a function that parses DER with various errors and
- * violations. This is not a part of the library itself, because the allowed
- * violations are chosen arbitrarily and do not follow or establish any
- * standard.
- *
- * In many places it matters that different implementations do not only accept
- * the same set of valid signatures, but also reject the same set of signatures.
- * The only means to accomplish that is by strictly obeying a standard, and not
- * accepting anything else.
- *
- * Nonetheless, sometimes there is a need for compatibility with systems that
- * use signatures which do not strictly obey DER. The snippet below shows how
- * certain violations are easily supported. You may need to adapt it.
- *
- * Do not use this for new systems. Use well-defined DER or compact signatures
- * instead if you have the choice (see secp256k1_ecdsa_signature_parse_der and
- * secp256k1_ecdsa_signature_parse_compact).
- *
- * The supported violations are:
- * - All numbers are parsed as nonnegative integers, even though X.609-0207
- *   section 8.3.3 specifies that integers are always encoded as two's
- *   complement.
- * - Integers can have length 0, even though section 8.3.1 says they can't.
- * - Integers with overly long padding are accepted, violation section
- *   8.3.2.
- * - 127-byte long length descriptors are accepted, even though section
- *   8.1.3.5.c says that they are not.
- * - Trailing garbage data inside or after the signature is ignored.
- * - The length descriptor of the sequence is ignored.
- *
- * Compared to for example OpenSSL, many violations are NOT supported:
- * - Using overly long tag descriptors for the sequence or integers inside,
- *   violating section 8.1.2.2.
- * - Encoding primitive integers as constructed values, violating section
- *   8.3.1.

+# Builder - fluent immutable builders for Go
+
+[![GoDoc](https://godoc.org/github.com/lann/builder?status.png)](https://godoc.org/github.com/lann/builder)
+[![Build Status](https://travis-ci.org/lann/builder.png?branch=master)](https://travis-ci.org/lann/builder)
+
+Builder was originally written for
+[Squirrel](https://github.com/lann/squirrel), a fluent SQL generator. It
+is probably the best example of Builder in action.
+
+Builder helps you write **fluent** DSLs for your libraries with method chaining:
+
+```go
+resp := ReqBuilder.
+    Url("http://golang.org").
+    Header("User-Agent", "Builder").
+    Get()
+```
+
+Builder uses **immutable** persistent data structures
+([these](https://github.com/mndrix/ps), specifically)
+so that each step in your method chain can be reused:
+
+```go
+build := WordBuilder.AddLetters("Build")
+builder := build.AddLetters("er")
+building := build.AddLetters("ing")
+```
+
+Builder makes it easy to **build** structs using the **builder** pattern
+(*surprise!*):
+
+```go
+import "github.com/lann/builder"
+
+type Muppet struct {
+    Name string
+    Friends []string
+}
+
+type muppetBuilder builder.Builder
+
+func (b muppetBuilder) Name(name string) muppetBuilder {
+    return builder.Set(b, "Name", name).(muppetBuilder)
+}
+
+func (b muppetBuilder) AddFriend(friend string) muppetBuilder {
+    return builder.Append(b, "Friends", friend).(muppetBuilder)
+}
+
+func (b muppetBuilder) Build() Muppet {
+    return builder.GetStruct(b).(Muppet)
+}
+
+var MuppetBuilder = builder.Register(muppetBuilder{}, Muppet{}).(muppetBuilder)
+```
+```go
+MuppetBuilder.
+    Name("Beaker").
+    AddFriend("Dr. Honeydew").
+    Build()
+
+=> Muppet{Name:"Beaker", Friends:[]string{"Dr. Honeydew"}}
+```
