# go-ansiterm
This is a cross platform Ansi Terminal Emulation library. It reads a stream of Ansi characters and produces the appropriate function calls. The results of the function calls are platform dependent.
For example the parser might receive "ESC, [, A" as a stream of three characters. This is the code for Cursor Up (http://www.vt100.net/docs/vt510-rm/CUU). The parser then calls the cursor up function (CUU()) on an event handler. The event handler determines what platform specific work must be done to cause the cursor to move up one position.
The parser (parser.go) is a partial implementation of this state machine (http://vt100.net/emu/vt500_parser.png). There are also two event handler implementations, one for tests (test_event_handler.go) to validate that the expected events are being produced and called, the other is a Windows implementation (winterm/win_event_handler.go).
See parser_test.go for examples exercising the state machine and generating appropriate function calls.

// variables) the pointers reference *before* the API completes.
//
// As a result, in those cases, the code must hint that the variables remain in active by invoking the

// require unsafe pointers.

// If you add or modify methods, ENSURE protection of local variables through the "use" builtin to inform
// the garbage collector the variables remain in use if:
//
// -- The value is not a pointer (e.g., int32, struct)

## cache
cache is a Go cache manager. It can use many cache adapters. The repo is inspired by `database/sql` .
## How to install?
go get github.com/beego/beego/v2/client/cache
## What adapters are supported?
As of now this cache support memory, Memcache and Redis.
## How to use it?
First you must import it
import (
"github.com/beego/beego/v2/client/cache"
)
Then init a Cache (example with memory adapter)
bm, err := cache.NewCache("memory", `{"interval":60}`)
Use it like this:
bm.Put("astaxie", 1, 10 * time.Second)
bm.Get("astaxie")
bm.IsExist("astaxie")
bm.Delete("astaxie")
## Memory adapter
Configure memory adapter like this:
{"interval":60}
interval means the gc time. The cache will check at each time interval, whether item has expired.
## Memcache adapter
Memcache adapter use the [gomemcache](http://github.com/bradfitz/gomemcache) client.
Configure like this:
{"conn":"127.0.0.1:11211"}
## Redis adapter
Redis adapter use the [redigo](http://github.com/gomodule/redigo) client.
Configure like this:
{"conn":":6039"}

// Package filters defines a syntax and parser that can be used for the
// filtration of items across the containerd API. The core is built on the
// concept of protobuf field paths, with quoting. Several operators allow the
// user to flexibly select items based on field presence, equality, inequality
// and regular expressions. Flexible adaptors support working with any type.
//
// The syntax is fairly familiar, if you've used container ecosystem
// projects. At the core, we base it on the concept of protobuf field
// paths, augmenting with the ability to quote portions of the field path
// to match arbitrary labels. These "selectors" come in the following
// syntax:
//
// ```
// <fieldpath>[<operator><value>]
// ```
//
// A basic example is as follows:
//
// ```
// name==foo
// ```
//
// This would match all objects that have a field `name` with the value
// `foo`. If we only want to test if the field is present, we can omit the
// operator. This is most useful for matching labels in containerd. The
// following will match objects that have the field "labels" and have the
// label "foo" defined:
//
// ```
// labels.foo
// ```
//
// We also allow for quoting of parts of the field path to allow matching
// of arbitrary items:
//
// ```
// labels."very complex label"==something
// ```
//
// We also define `!=` and `~=` as operators. The `!=` will match all
// objects that don't match the value for a field and `~=` will compile the
// target value as a regular expression and match the field value against that.
//
// Selectors can be combined using a comma, such that the resulting
// selector will require all selectors are matched for the object to match.
// The following example will match objects that are named `foo` and have
// the label `bar`:
//
// ```
// name==foo,labels.bar
// ```

Parse the strings into a filter that may be used with an adaptor.
The filter is made up of zero or more selectors.
The format is a comma separated list of expressions, in the form of
`<fieldpath><op><value>`, known as selectors. All selectors must match the
target object for the filter to be true.
We define the operators "==" for equality, "!=" for not equal and "~=" for a
regular expression. If the operator and value are not present, the matcher will
test for the presence of a value, as defined by the target object.
The formal grammar is as follows:
selectors := selector ("," selector)*
selector := fieldpath (operator value)
fieldpath := field ('.' field)*
field := quoted | [A-Za-z] [A-Za-z0-9_]+
operator := "==" | "!=" | "~="
value := quoted | [^\s,]+
quoted := <go string syntax>

// Package platforms provides a toolkit for normalizing, matching and
// specifying container platforms.
//
// Centered around OCI platform specifications, we define a string-based
// specifier syntax that can be used for user input. With a specifier, users
// only need to specify the parts of the platform that are relevant to their
// context, providing an operating system or architecture or both.
//
// How do I use this package?
//
// The vast majority of use cases should simply use the match function with
// user input. The first step is to parse a specifier into a matcher:
//
// m, err := Parse("linux")
// if err != nil { ... }
//
// Once you have a matcher, use it to match against the platform declared by a
// component, typically from an image or runtime. Since extracting an images
// platform is a little more involved, we'll use an example against the
// platform default:
//
// if ok := m.Match(Default()); !ok { /* doesn't match */ }
//
// This can be composed in loops for resolving runtimes or used as a filter for
// fetch and select images.
//
// More details of the specifier syntax and platform spec follow.
//
// Declaring Platform Support
//
// Components that have strict platform requirements should use the OCI
// platform specification to declare their support. Typically, this will be
// images and runtimes that should make these declaring which platform they
// support specifically. This looks roughly as follows:
//
// type Platform struct {
// Architecture string
// OS string
// Variant string
// }
//
// Most images and runtimes should at least set Architecture and OS, according
// to their GOARCH and GOOS values, respectively (follow the OCI image
// specification when in doubt). ARM should set variant under certain
// discussions, which are outlined below.
//
// Platform Specifiers
//
// While the OCI platform specifications provide a tool for components to
// specify structured information, user input typically doesn't need the full
// context and much can be inferred. To solve this problem, we introduced
// "specifiers". A specifier has the format
// `<os>|<arch>|<os>/<arch>[/<variant>]`. The user can provide either the
// operating system or the architecture or both.
//
// An example of a common specifier is `linux/amd64`. If the host has a default
// of runtime that matches this, the user can simply provide the component that
// matters. For example, if a image provides amd64 and arm64 support, the
// operating system, `linux` can be inferred, so they only have to provide
// `arm64` or `amd64`. Similar behavior is implemented for operating systems,
// where the architecture may be known but a runtime may support images from
// different operating systems.
//
// Normalization
//
// Because not all users are familiar with the way the Go runtime represents
// platforms, several normalizations have been provided to make this package
// easier to user.
//
// The following are performed for architectures:
//
// Value Normalized
// aarch64 arm64
// armhf arm
// armel arm/v6
// i386 386
// x86_64 amd64
// x86-64 amd64
//
// We also normalize the operating system `macos` to `darwin`.
//
// ARM Support
//
// To qualify ARM architecture, the Variant field is used to qualify the arm
// version. The most common arm version, v7, is represented without the variant
// unless it is explicitly provided. This is treated as equivalent to armhf. A
// previous architecture, armel, will be normalized to arm/v6.
//
// While these normalizations are provided, their support on arm platforms has
// not yet been fully implemented and tested.
