parsers
=======
This directory contains pre-built, custom parsers that can be used with `env.ParseWithFuncs`
to facilitate the parsing of envs that are not basic types.
Example Usage:
```golang
package main

"log"
"net/url"
"github.com/caarlos0/env"
"github.com/caarlos0/env/parsers"
)
type config struct {

# Contributing to Go
Go is an open source project.
It is the work of hundreds of contributors. We appreciate your help!
## Filing issues
When [filing an issue](https://golang.org/issue/new), make sure to answer these five questions:
1. What version of Go are you using (`go version`)?
2. What operating system and processor architecture are you using?
3. What did you do?
4. What did you expect to see?
5. What did you see instead?
General questions should go to the [golang-nuts mailing list](https://groups.google.com/group/golang-nuts) instead of the issue tracker.
The gophers there will answer or ask you to file an issue if you've tripped over a bug.
## Contributing code
Please read the [Contribution Guidelines](https://golang.org/doc/contribute.html)
before sending patches.

Package bpf implements marshaling and unmarshaling of programs for the
Berkeley Packet Filter virtual machine, and provides a Go implementation
of the virtual machine.
BPF's main use is to specify a packet filter for network taps, so that
the kernel doesn't have to expensively copy every packet it sees to
userspace. However, it's been repurposed to other areas where running
user code in-kernel is needed. For example, Linux's seccomp uses BPF
to apply security policies to system calls. For simplicity, this
documentation refers only to packets, but other uses of BPF have their
own data payloads.
BPF programs run in a restricted virtual machine. It has almost no
access to kernel functions, and while conditional branches are
allowed, they can only jump forwards, to guarantee that there are no
infinite loops.
The virtual machine
The BPF VM is an accumulator machine. Its main register, called
register A, is an implicit source and destination in all arithmetic
and logic operations. The machine also has 16 scratch registers for
temporary storage, and an indirection register (register X) for
indirect memory access. All registers are 32 bits wide.
Each run of a BPF program is given one packet, which is placed in the
VM's read-only "main memory". LoadAbsolute and LoadIndirect
instructions can fetch up to 32 bits at a time into register A for
examination.
The goal of a BPF program is to produce and return a verdict (uint32),
which tells the kernel what to do with the packet. In the context of
packet filtering, the returned value is the number of bytes of the
packet to forward to userspace, or 0 to ignore the packet. Other
contexts like seccomp define their own return values.
In order to simplify programs, attempts to read past the end of the
packet terminate the program execution with a verdict of 0 (ignore
packet). This means that the vast majority of BPF programs don't need
to do any explicit bounds checking.
In addition to the bytes of the packet, some BPF programs have access
to extensions, which are essentially calls to kernel utility
functions. Currently, the only extensions supported by this package
are the Linux packet filter extensions.
Examples
This packet filter selects all ARP packets.
bpf.Assemble([]bpf.Instruction{
// Load "EtherType" field from the ethernet header.
bpf.LoadAbsolute{Off: 12, Size: 2},
// Skip over the next instruction if EtherType is not ARP.
bpf.JumpIf{Cond: bpf.JumpNotEqual, Val: 0x0806, SkipTrue: 1},
// Verdict is "send up to 4k of the packet to userspace."
bpf.RetConstant{Val: 4096},
// Verdict is "ignore packet."
bpf.RetConstant{Val: 0},
})
This packet filter captures a random 1% sample of traffic.
bpf.Assemble([]bpf.Instruction{
// Get a 32-bit random number from the Linux kernel.
bpf.LoadExtension{Num: bpf.ExtRand},
// 1% dice roll?
bpf.JumpIf{Cond: bpf.JumpLessThan, Val: 2^32/100, SkipFalse: 1},
// Capture.
bpf.RetConstant{Val: 4096},
// Ignore.
bpf.RetConstant{Val: 0},
})

/*
Package html implements an HTML5-compliant tokenizer and parser.
Tokenization is done by creating a Tokenizer for an io.Reader r. It is the
caller's responsibility to ensure that r provides UTF-8 encoded HTML.
z := html.NewTokenizer(r)
Given a Tokenizer z, the HTML is tokenized by repeatedly calling z.Next(),
which parses the next token and returns its type, or an error:
for {
tt := z.Next()
if tt == html.ErrorToken {
// ...
return ...
}
// Process the current token.
}
There are two APIs for retrieving the current token. The high-level API is to
call Token; the low-level API is to call Text or TagName / TagAttr. Both APIs
allow optionally calling Raw after Next but before Token, Text, TagName, or
TagAttr. In EBNF notation, the valid call sequence per token is:
Next {Raw} [ Token | Text | TagName {TagAttr} ]
Token returns an independent data structure that completely describes a token.
Entities (such as "&lt;") are unescaped, tag names and attribute keys are
lower-cased, and attributes are collected into a []Attribute. For example:
for {
if z.Next() == html.ErrorToken {
// Returning io.EOF indicates success.
return z.Err()
}
emitToken(z.Token())
}
The low-level API performs fewer allocations and copies, but the contents of
the []byte values returned by Text, TagName and TagAttr may change on the next
call to Next. For example, to extract an HTML page's anchor text:
depth := 0
for {
tt := z.Next()
switch tt {
case html.ErrorToken:
return z.Err()
case html.TextToken:
if depth > 0 {
// emitBytes should copy the []byte it receives,
// if it doesn't process it immediately.
emitBytes(z.Text())
}
case html.StartTagToken, html.EndTagToken:
tn, _ := z.TagName()
if len(tn) == 1 && tn[0] == 'a' {
if tt == html.StartTagToken {
depth++
} else {
depth--
}
}
}
}
Parsing is done by calling Parse with an io.Reader, which returns the root of
the parse tree (the document element) as a *Node. It is the caller's
responsibility to ensure that the Reader provides UTF-8 encoded HTML. For
example, to process each anchor node in depth-first order:
doc, err := html.Parse(r)
if err != nil {
// ...
}
var f func(*html.Node)
f = func(n *html.Node) {
if n.Type == html.ElementNode && n.Data == "a" {
// Do something with n...
}
for c := n.FirstChild; c != nil; c = c.NextSibling {
f(c)
}
}
f(doc)
The relevant specifications include:
https://html.spec.whatwg.org/multipage/syntax.html and
https://html.spec.whatwg.org/multipage/syntax.html#tokenization
*/
package html // import "golang.org/x/net/html"
// The tokenization algorithm implemented by this package is not a line-by-line
// transliteration of the relatively verbose state-machine in the WHATWG
// specification. A more direct approach is used instead, where the program
// counter implies the state, such as whether it is tokenizing a tag or a text
// node. Specification compliance is verified by checking expected and actual
// outputs over a test suite rather than aiming for algorithmic fidelity.
// TODO(nigeltao): Does a DOM API belong in this package or a separate one?
// TODO(nigeltao): How does parsing interact with a JavaScript engine?

// Render renders the parse tree n to the given writer.
//
// Rendering is done on a 'best effort' basis: calling Parse on the output of
// Render will always result in something similar to the original tree, but it
// is not necessarily an exact clone unless the original tree was 'well-formed'.
// 'Well-formed' is not easily specified; the HTML5 specification is
// complicated.
//
// Calling Parse on arbitrary input typically results in a 'well-formed' parse
// tree. However, it is possible for Parse to yield a 'badly-formed' parse tree.
// For example, in a 'well-formed' parse tree, no <a> element is a child of
// another <a> element: parsing "<a><a>" results in two sibling elements.
// Similarly, in a 'well-formed' parse tree, no <a> element is a child of a
// <table> element: parsing "<p><table><a>" results in a <p> with two sibling
// children; the <a> is reparented to the <table>'s parent. However, calling
// Parse on "<a><table><a>" does not return an error, but the result has an <a>
// element with an <a> child, and is therefore not 'well-formed'.
//
// Programmatically constructed trees are typically also 'well-formed', but it
// is possible to construct a tree that looks innocuous but, when rendered and
// re-parsed, results in a different tree. A simple example is that a solitary
// text node would become a tree containing <html>, <head> and <body> elements.
// Another example is that the programmatic equivalent of "a<head>b</head>c"
// becomes "<html><head><head/><body>abc</body></html>".
