Blackfriday [![Build Status](https://travis-ci.org/russross/blackfriday.svg?branch=master)](https://travis-ci.org/russross/blackfriday)
|
||||
===========
|
||||
|
||||
Blackfriday is a [Markdown][1] processor implemented in [Go][2]. It
|
||||
is paranoid about its input (so you can safely feed it user-supplied
|
||||
data), it is fast, it supports common extensions (tables, smart
|
||||
punctuation substitutions, etc.), and it is safe for all utf-8
|
||||
(unicode) input.
|
||||
|
||||
HTML output is currently supported, along with Smartypants
|
||||
extensions.
|
||||
|
||||
It started as a translation from C of [Sundown][3].
|
||||
|
||||
|
||||
Installation
|
||||
------------
|
||||
|
||||
Blackfriday is compatible with any modern Go release. With Go 1.7 and git
|
||||
installed:
|
||||
|
||||
go get gopkg.in/russross/blackfriday.v2
|
||||
|
||||
will download, compile, and install the package into your `$GOPATH`
|
||||
directory hierarchy. Alternatively, you can achieve the same if you
|
||||
import it into a project:
|
||||
|
||||
import "gopkg.in/russross/blackfriday.v2"
|
||||
|
||||
and `go get` without parameters.
|
||||
|
||||
|
||||
Versions
|
||||
--------
|
||||
|
||||
Currently maintained and recommended version of Blackfriday is `v2`. It's being
|
||||
developed on its own branch: https://github.com/russross/blackfriday/tree/v2 and the
|
||||
documentation is available at
|
||||
https://godoc.org/gopkg.in/russross/blackfriday.v2.
|
||||
|
||||
It is `go get`-able via via [gopkg.in][6] at `gopkg.in/russross/blackfriday.v2`,
|
||||
but we highly recommend using package management tool like [dep][7] or
|
||||
[Glide][8] and make use of semantic versioning. With package management you
|
||||
should import `github.com/russross/blackfriday` and specify that you're using
|
||||
version 2.0.0.
|
||||
|
||||
Version 2 offers a number of improvements over v1:
|
||||
|
||||
* Cleaned up API
|
||||
* A separate call to [`Parse`][4], which produces an abstract syntax tree for
|
||||
the document
|
||||
* Latest bug fixes
|
||||
* Flexibility to easily add your own rendering extensions
|
||||
|
||||
Potential drawbacks:
|
||||
|
||||
* Our benchmarks show v2 to be slightly slower than v1. Currently in the
|
||||
ballpark of around 15%.
|
||||
* API breakage. If you can't afford modifying your code to adhere to the new API
|
||||
and don't care too much about the new features, v2 is probably not for you.
|
||||
* Several bug fixes are trailing behind and still need to be forward-ported to
|
||||
v2. See issue [#348](https://github.com/russross/blackfriday/issues/348) for
|
||||
tracking.
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
For the most sensible markdown processing, it is as simple as getting your input
|
||||
into a byte slice and calling:
|
||||
|
||||
```go
|
||||
output := blackfriday.Run(input)
|
||||
```
|
||||
|
||||
Your input will be parsed and the output rendered with a set of most popular
|
||||
extensions enabled. If you want the most basic feature set, corresponding with
|
||||
the bare Markdown specification, use:
|
||||
|
||||
```go
|
||||
output := blackfriday.Run(input, blackfriday.WithNoExtensions())
|
||||
```
|
||||
|
||||
### Sanitize untrusted content
|
||||
|
||||
Blackfriday itself does nothing to protect against malicious content. If you are
|
||||
dealing with user-supplied markdown, we recommend running Blackfriday's output
|
||||
through HTML sanitizer such as [Bluemonday][5].
|
||||
|
||||
Here's an example of simple usage of Blackfriday together with Bluemonday:
|
||||
|
||||
```go
|
||||
import (
|
||||
"github.com/microcosm-cc/bluemonday"
|
||||
"github.com/russross/blackfriday"
|
||||
)
|
||||
|
||||
// ...
|
||||
unsafe := blackfriday.Run(input)
|
||||
html := bluemonday.UGCPolicy().SanitizeBytes(unsafe)
|
||||
```
|
||||
|
||||
### Custom options
|
||||
|
||||
If you want to customize the set of options, use `blackfriday.WithExtensions`,
|
||||
`blackfriday.WithRenderer` and `blackfriday.WithRefOverride`.
|
||||
|
||||
You can also check out `blackfriday-tool` for a more complete example
|
||||
of how to use it. Download and install it using:
|
||||
|
||||
go get github.com/russross/blackfriday-tool
|
||||
|
||||
This is a simple command-line tool that allows you to process a
|
||||
markdown file using a standalone program. You can also browse the
|
||||
source directly on github if you are just looking for some example
|
||||
code:
|
||||
|
||||
* <http://github.com/russross/blackfriday-tool>
|
||||
|
||||
Note that if you have not already done so, installing
|
||||
`blackfriday-tool` will be sufficient to download and install
|
||||
blackfriday in addition to the tool itself. The tool binary will be
|
||||
installed in `$GOPATH/bin`. This is a statically-linked binary that
|
||||
can be copied to wherever you need it without worrying about
|
||||
dependencies and library versions.
|
||||
|
||||
|
||||
Features
|
||||
--------
|
||||
|
||||
All features of Sundown are supported, including:
|
||||
|
||||
* **Compatibility**. The Markdown v1.0.3 test suite passes with
|
||||
the `--tidy` option. Without `--tidy`, the differences are
|
||||
mostly in whitespace and entity escaping, where blackfriday is
|
||||
more consistent and cleaner.
|
||||
|
||||
* **Common extensions**, including table support, fenced code
|
||||
blocks, autolinks, strikethroughs, non-strict emphasis, etc.
|
||||
|
||||
* **Safety**. Blackfriday is paranoid when parsing, making it safe
|
||||
to feed untrusted user input without fear of bad things
|
||||
happening. The test suite stress tests this and there are no
|
||||
known inputs that make it crash. If you find one, please let me
|
||||
know and send me the input that does it.
|
||||
|
||||
NOTE: "safety" in this context means *runtime safety only*. In order to
|
||||
protect yourself against JavaScript injection in untrusted content, see
|
||||
[this example](https://github.com/russross/blackfriday#sanitize-untrusted-content).
|
||||
|
||||
* **Fast processing**. It is fast enough to render on-demand in
|
||||
most web applications without having to cache the output.
|
||||
|
||||
* **Thread safety**. You can run multiple parsers in different
|
||||
goroutines without ill effect. There is no dependence on global
|
||||
shared state.
|
||||
|
||||
* **Minimal dependencies**. Blackfriday only depends on standard
|
||||
library packages in Go. The source code is pretty
|
||||
self-contained, so it is easy to add to any project, including
|
||||
Google App Engine projects.
|
||||
|
||||
* **Standards compliant**. Output successfully validates using the
|
||||
W3C validation tool for HTML 4.01 and XHTML 1.0 Transitional.
|
||||
|
||||
|
||||
Extensions
|
||||
----------
|
||||
|
||||
In addition to the standard markdown syntax, this package
|
||||
implements the following extensions:
|
||||
|
||||
* **Intra-word emphasis supression**. The `_` character is
|
||||
commonly used inside words when discussing code, so having
|
||||
markdown interpret it as an emphasis command is usually the
|
||||
wrong thing. Blackfriday lets you treat all emphasis markers as
|
||||
normal characters when they occur inside a word.
|
||||
|
||||
* **Tables**. Tables can be created by drawing them in the input
|
||||
using a simple syntax:
|
||||
|
||||
```
|
||||
Name | Age
|
||||
--------|------
|
||||
Bob | 27
|
||||
Alice | 23
|
||||
```
|
||||
|
||||
* **Fenced code blocks**. In addition to the normal 4-space
|
||||
indentation to mark code blocks, you can explicitly mark them
|
||||
and supply a language (to make syntax highlighting simple). Just
|
||||
mark it like this:
|
||||
|
||||
```go
|
||||
func getTrue() bool {
|
||||
return true
|
||||
}
|
||||
```
|
||||
|
||||
You can use 3 or more backticks to mark the beginning of the
|
||||
block, and the same number to mark the end of the block.
|
||||
|
||||
* **Definition lists**. A simple definition list is made of a single-line
|
||||
term followed by a colon and the definition for that term.
|
||||
|
||||
Cat
|
||||
: Fluffy animal everyone likes
|
||||
|
||||
Internet
|
||||
: Vector of transmission for pictures of cats
|
||||
|
||||
Terms must be separated from the previous definition by a blank line.
|
||||
|
||||
* **Footnotes**. A marker in the text that will become a superscript number;
|
||||
a footnote definition that will be placed in a list of footnotes at the
|
||||
end of the document. A footnote looks like this:
|
||||
|
||||
This is a footnote.[^1]
|
||||
|
||||
[^1]: the footnote text.
|
||||
|
||||
* **Autolinking**. Blackfriday can find URLs that have not been
|
||||
explicitly marked as links and turn them into links.
|
||||
|
||||
* **Strikethrough**. Use two tildes (`~~`) to mark text that
|
||||
should be crossed out.
|
||||
|
||||
* **Hard line breaks**. With this extension enabled newlines in the input
|
||||
translate into line breaks in the output. This extension is off by default.
|
||||
|
||||
* **Smart quotes**. Smartypants-style punctuation substitution is
|
||||
supported, turning normal double- and single-quote marks into
|
||||
curly quotes, etc.
|
||||
|
||||
* **LaTeX-style dash parsing** is an additional option, where `--`
|
||||
is translated into `–`, and `---` is translated into
|
||||
`—`. This differs from most smartypants processors, which
|
||||
turn a single hyphen into an ndash and a double hyphen into an
|
||||
mdash.
|
||||
|
||||
* **Smart fractions**, where anything that looks like a fraction
|
||||
is translated into suitable HTML (instead of just a few special
|
||||
cases like most smartypant processors). For example, `4/5`
|
||||
becomes `<sup>4</sup>⁄<sub>5</sub>`, which renders as
|
||||
<sup>4</sup>⁄<sub>5</sub>.
|
||||
|
||||
|
||||
Other renderers
|
||||
---------------
|
||||
|
||||
Blackfriday is structured to allow alternative rendering engines. Here
|
||||
are a few of note:
|
||||
|
||||
* [github_flavored_markdown](https://godoc.org/github.com/shurcooL/github_flavored_markdown):
|
||||
provides a GitHub Flavored Markdown renderer with fenced code block
|
||||
highlighting, clickable heading anchor links.
|
||||
|
||||
It's not customizable, and its goal is to produce HTML output
|
||||
equivalent to the [GitHub Markdown API endpoint](https://developer.github.com/v3/markdown/#render-a-markdown-document-in-raw-mode),
|
||||
except the rendering is performed locally.
|
||||
|
||||
* [markdownfmt](https://github.com/shurcooL/markdownfmt): like gofmt,
|
||||
but for markdown.
|
||||
|
||||
* [LaTeX output](https://github.com/Ambrevar/Blackfriday-LaTeX):
|
||||
renders output as LaTeX.
|
||||
|
||||
* [Blackfriday-Confluence](https://github.com/kentaro-m/blackfriday-confluence): provides a [Confluence Wiki Markup](https://confluence.atlassian.com/doc/confluence-wiki-markup-251003035.html) renderer.
|
||||
|
||||
|
||||
Todo
|
||||
----
|
||||
|
||||
* More unit testing
|
||||
* Improve unicode support. It does not understand all unicode
|
||||
rules (about what constitutes a letter, a punctuation symbol,
|
||||
etc.), so it may fail to detect word boundaries correctly in
|
||||
some instances. It is safe on all utf-8 input.

# Change Log
|
||||
|
||||
**ATTN**: This project uses [semantic versioning](http://semver.org/).
|
||||
|
||||
## [Unreleased]
|
||||
|
||||
## 1.20.0 - 2017-08-10
|
||||
|
||||
### Fixed
|
||||
|
||||
* `HandleExitCoder` is now correctly iterates over all errors in
|
||||
a `MultiError`. The exit code is the exit code of the last error or `1` if
|
||||
there are no `ExitCoder`s in the `MultiError`.
|
||||
* Fixed YAML file loading on Windows (previously would fail validate the file path)
|
||||
* Subcommand `Usage`, `Description`, `ArgsUsage`, `OnUsageError` correctly
|
||||
propogated
|
||||
* `ErrWriter` is now passed downwards through command structure to avoid the
|
||||
need to redefine it
|
||||
* Pass `Command` context into `OnUsageError` rather than parent context so that
|
||||
all fields are avaiable
|
||||
* Errors occuring in `Before` funcs are no longer double printed
|
||||
* Use `UsageText` in the help templates for commands and subcommands if
|
||||
defined; otherwise build the usage as before (was previously ignoring this
|
||||
field)
|
||||
* `IsSet` and `GlobalIsSet` now correctly return whether a flag is set if
|
||||
a program calls `Set` or `GlobalSet` directly after flag parsing (would
|
||||
previously only return `true` if the flag was set during parsing)
|
||||
|
||||
### Changed
|
||||
|
||||
* No longer exit the program on command/subcommand error if the error raised is
|
||||
not an `OsExiter`. This exiting behavior was introduced in 1.19.0, but was
|
||||
determined to be a regression in functionality. See [the
|
||||
PR](https://github.com/urfave/cli/pull/595) for discussion.
|
||||
|
||||
### Added
|
||||
|
||||
* `CommandsByName` type was added to make it easy to sort `Command`s by name,
|
||||
alphabetically
|
||||
* `altsrc` now handles loading of string and int arrays from TOML
|
||||
* Support for definition of custom help templates for `App` via
|
||||
`CustomAppHelpTemplate`
|
||||
* Support for arbitrary key/value fields on `App` to be used with
|
||||
`CustomAppHelpTemplate` via `ExtraInfo`
|
||||
* `HelpFlag`, `VersionFlag`, and `BashCompletionFlag` changed to explictly be
|
||||
`cli.Flag`s allowing for the use of custom flags satisfying the `cli.Flag`
|
||||
interface to be used.
|
||||
|
||||
|
||||
## [1.19.1] - 2016-11-21
|
||||
|
||||
### Fixed
|
||||
|
||||
- Fixes regression introduced in 1.19.0 where using an `ActionFunc` as
|
||||
the `Action` for a command would cause it to error rather than calling the
|
||||
function. Should not have a affected declarative cases using `func(c
|
||||
*cli.Context) err)`.
|
||||
- Shell completion now handles the case where the user specifies
|
||||
`--generate-bash-completion` immediately after a flag that takes an argument.
|
||||
Previously it call the application with `--generate-bash-completion` as the
|
||||
flag value.
|
||||
|
||||
## [1.19.0] - 2016-11-19
|
||||
### Added
|
||||
- `FlagsByName` was added to make it easy to sort flags (e.g. `sort.Sort(cli.FlagsByName(app.Flags))`)
|
||||
- A `Description` field was added to `App` for a more detailed description of
|
||||
the application (similar to the existing `Description` field on `Command`)
|
||||
- Flag type code generation via `go generate`
|
||||
- Write to stderr and exit 1 if action returns non-nil error
|
||||
- Added support for TOML to the `altsrc` loader
|
||||
- `SkipArgReorder` was added to allow users to skip the argument reordering.
|
||||
This is useful if you want to consider all "flags" after an argument as
|
||||
arguments rather than flags (the default behavior of the stdlib `flag`
|
||||
library). This is backported functionality from the [removal of the flag
|
||||
reordering](https://github.com/urfave/cli/pull/398) in the unreleased version
|
||||
2
|
||||
- For formatted errors (those implementing `ErrorFormatter`), the errors will
|
||||
be formatted during output. Compatible with `pkg/errors`.
|
||||
|
||||
### Changed
|
||||
- Raise minimum tested/supported Go version to 1.2+
|
||||
|
||||
### Fixed
|
||||
- Consider empty environment variables as set (previously environment variables
|
||||
with the equivalent of `""` would be skipped rather than their value used).
|
||||
- Return an error if the value in a given environment variable cannot be parsed
|
||||
as the flag type. Previously these errors were silently swallowed.
|
||||
- Print full error when an invalid flag is specified (which includes the invalid flag)
|
||||
- `App.Writer` defaults to `stdout` when `nil`
|
||||
- If no action is specified on a command or app, the help is now printed instead of `panic`ing
|
||||
- `App.Metadata` is initialized automatically now (previously was `nil` unless initialized)
|
||||
- Correctly show help message if `-h` is provided to a subcommand
|
||||
- `context.(Global)IsSet` now respects environment variables. Previously it
|
||||
would return `false` if a flag was specified in the environment rather than
|
||||
as an argument
|
||||
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
|
||||
- `altsrc`s import paths were updated to use `gopkg.in/urfave/cli.v1`. This
|
||||
fixes issues that occurred when `gopkg.in/urfave/cli.v1` was imported as well
|
||||
as `altsrc` where Go would complain that the types didn't match
|
||||
|
||||
## [1.18.1] - 2016-08-28
|
||||
### Fixed
|
||||
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user (backported)
|
||||
|
||||
## [1.18.0] - 2016-06-27
|
||||
### Added
|
||||
- `./runtests` test runner with coverage tracking by default
|
||||
- testing on OS X
|
||||
- testing on Windows
|
||||
- `UintFlag`, `Uint64Flag`, and `Int64Flag` types and supporting code
|
||||
|
||||
### Changed
|
||||
- Use spaces for alignment in help/usage output instead of tabs, making the
|
||||
output alignment consistent regardless of tab width
|
||||
|
||||
### Fixed
|
||||
- Printing of command aliases in help text
|
||||
- Printing of visible flags for both struct and struct pointer flags
|
||||
- Display the `help` subcommand when using `CommandCategories`
|
||||
- No longer swallows `panic`s that occur within the `Action`s themselves when
|
||||
detecting the signature of the `Action` field
|
||||
|
||||
## [1.17.1] - 2016-08-28
|
||||
### Fixed
|
||||
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
|
||||
|
||||
## [1.17.0] - 2016-05-09
|
||||
### Added
|
||||
- Pluggable flag-level help text rendering via `cli.DefaultFlagStringFunc`
|
||||
- `context.GlobalBoolT` was added as an analogue to `context.GlobalBool`
|
||||
- Support for hiding commands by setting `Hidden: true` -- this will hide the
|
||||
commands in help output
|
||||
|
||||
### Changed
|
||||
- `Float64Flag`, `IntFlag`, and `DurationFlag` default values are no longer
|
||||
quoted in help text output.
|
||||
- All flag types now include `(default: {value})` strings following usage when a
|
||||
default value can be (reasonably) detected.
|
||||
- `IntSliceFlag` and `StringSliceFlag` usage strings are now more consistent
|
||||
with non-slice flag types
|
||||
- Apps now exit with a code of 3 if an unknown subcommand is specified
|
||||
(previously they printed "No help topic for...", but still exited 0. This
|
||||
makes it easier to script around apps built using `cli` since they can trust
|
||||
that a 0 exit code indicated a successful execution.
|
||||
- cleanups based on [Go Report Card
|
||||
feedback](https://goreportcard.com/report/github.com/urfave/cli)
|
||||
|
||||
## [1.16.1] - 2016-08-28
|
||||
### Fixed
|
||||
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
|
||||
|
||||
## [1.16.0] - 2016-05-02
|
||||
### Added
|
||||
- `Hidden` field on all flag struct types to omit from generated help text
|
||||
|
||||
### Changed
|
||||
- `BashCompletionFlag` (`--enable-bash-completion`) is now omitted from
|
||||
generated help text via the `Hidden` field
|
||||
|
||||
### Fixed
|
||||
- handling of error values in `HandleAction` and `HandleExitCoder`
|
||||
|
||||
## [1.15.0] - 2016-04-30
|
||||
### Added
|
||||
- This file!
|
||||
- Support for placeholders in flag usage strings
|
||||
- `App.Metadata` map for arbitrary data/state management
|
||||
- `Set` and `GlobalSet` methods on `*cli.Context` for altering values after
|
||||
parsing.
|
||||
- Support for nested lookup of dot-delimited keys in structures loaded from
|
||||
YAML.
|
||||
|
||||
### Changed
|
||||
- The `App.Action` and `Command.Action` now prefer a return signature of
|
||||
`func(*cli.Context) error`, as defined by `cli.ActionFunc`. If a non-nil
|
||||
`error` is returned, there may be two outcomes:
|
||||
- If the error fulfills `cli.ExitCoder`, then `os.Exit` will be called
|
||||
automatically
|
||||
- Else the error is bubbled up and returned from `App.Run`
|
||||
- Specifying an `Action` with the legacy return signature of
|
||||
`func(*cli.Context)` will produce a deprecation message to stderr
|
||||
- Specifying an `Action` that is not a `func` type will produce a non-zero exit
|
||||
from `App.Run`
|
||||
- Specifying an `Action` func that has an invalid (input) signature will
|
||||
produce a non-zero exit from `App.Run`
|
||||
|
||||
### Deprecated
|
||||
- <a name="deprecated-cli-app-runandexitonerror"></a>
|
||||
`cli.App.RunAndExitOnError`, which should now be done by returning an error
|
||||
that fulfills `cli.ExitCoder` to `cli.App.Run`.
|
||||
- <a name="deprecated-cli-app-action-signature"></a> the legacy signature for
|
||||
`cli.App.Action` of `func(*cli.Context)`, which should now have a return
|
||||
signature of `func(*cli.Context) error`, as defined by `cli.ActionFunc`.
|
||||
|
||||
### Fixed
|
||||
- Added missing `*cli.Context.GlobalFloat64` method
|
||||
|
||||

|
||||

# Contributor Covenant Code of Conduct
|
||||
|
||||
## Our Pledge
|
||||
|
||||
In the interest of fostering an open and welcoming environment, we as
|
||||
contributors and maintainers pledge to making participation in our project and
|
||||
our community a harassment-free experience for everyone, regardless of age, body
|
||||
size, disability, ethnicity, gender identity and expression, level of experience,
|
||||
education, socio-economic status, nationality, personal appearance, race,
|
||||
religion, or sexual identity and orientation.
|
||||
|
||||
## Our Standards
|
||||
|
||||
Examples of behavior that contributes to creating a positive environment
|
||||
include:
|
||||
|
||||
* Using welcoming and inclusive language
|
||||
* Being respectful of differing viewpoints and experiences
|
||||
* Gracefully accepting constructive criticism
|
||||
* Focusing on what is best for the community
|
||||
* Showing empathy towards other community members
|
||||
|
||||
Examples of unacceptable behavior by participants include:
|
||||
|
||||
* The use of sexualized language or imagery and unwelcome sexual attention or
|
||||
advances
|
||||
* Trolling, insulting/derogatory comments, and personal or political attacks
|
||||
* Public or private harassment
|
||||
* Publishing others' private information, such as a physical or electronic
|
||||
address, without explicit permission
|
||||
* Other conduct which could reasonably be considered inappropriate in a
|
||||
professional setting
|
||||
|
||||
## Our Responsibilities
|
||||
|
||||
Project maintainers are responsible for clarifying the standards of acceptable
|
||||
behavior and are expected to take appropriate and fair corrective action in
|
||||
response to any instances of unacceptable behavior.
|
||||
|
||||
Project maintainers have the right and responsibility to remove, edit, or
|
||||
reject comments, commits, code, wiki edits, issues, and other contributions
|
||||
that are not aligned to this Code of Conduct, or to ban temporarily or
|
||||
permanently any contributor for other behaviors that they deem inappropriate,
|
||||
threatening, offensive, or harmful.
|
||||
|
||||
## Scope
|
||||
|
||||
This Code of Conduct applies both within project spaces and in public spaces
|
||||
when an individual is representing the project or its community. Examples of
|
||||
representing a project or community include using an official project e-mail
|
||||
address, posting via an official social media account, or acting as an appointed
|
||||
representative at an online or offline event. Representation of a project may be
|
||||
further defined and clarified by project maintainers.
|
||||
|
||||
## Enforcement
|
||||
|
||||
Instances of abusive, harassing, or otherwise unacceptable behavior may be
|
||||
reported by contacting Dan Buch at dan@meatballhat.com. All complaints will be
|
||||
reviewed and investigated and will result in a response that is deemed necessary
|
||||
and appropriate to the circumstances. The project team is obligated to maintain
|
||||
confidentiality with regard to the reporter of an incident. Further details of
|
||||
specific enforcement policies may be posted separately.
|
||||
|
||||
Project maintainers who do not follow or enforce the Code of Conduct in good
|
||||
faith may face temporary or permanent repercussions as determined by other
|
||||
members of the project's leadership.
|
||||
|
||||

"""
|
||||
The flag types that ship with the cli library have many things in common, and
|
||||
so we can take advantage of the `go generate` command to create much of the
|
||||
source code from a list of definitions. These definitions attempt to cover
|
||||
the parts that vary between flag types, and should evolve as needed.
|
||||
|
||||
An example of the minimum definition needed is:
|
||||
|
||||
{
|
||||
"name": "SomeType",
|
||||
"type": "sometype",
|
||||
"context_default": "nil"
|
||||
}
|
||||
|
||||
In this example, the code generated for the `cli` package will include a type
|
||||
named `SomeTypeFlag` that is expected to wrap a value of type `sometype`.
|
||||
Fetching values by name via `*cli.Context` will default to a value of `nil`.
|
||||
|
||||
A more complete, albeit somewhat redundant, example showing all available
|
||||
definition keys is:
|
||||
|
||||
{
|
||||
"name": "VeryMuchType",
|
||||
"type": "*VeryMuchType",
|
||||
"value": true,
|
||||
"dest": false,
|
||||
"doctail": " which really only wraps a []float64, oh well!",
|
||||
"context_type": "[]float64",
|
||||
"context_default": "nil",
|
||||
"parser": "parseVeryMuchType(f.Value.String())",
|
||||
"parser_cast": "[]float64(parsed)"
|
||||
}
|
||||
|
||||
The meaning of each field is as follows:
|
||||
|
||||
name (string) - The type "name", which will be suffixed with
|
||||
`Flag` when generating the type definition
|
||||
for `cli` and the wrapper type for `altsrc`
|
||||
type (string) - The type that the generated `Flag` type for `cli`
|
||||
is expected to "contain" as its `.Value` member
|
||||
value (bool) - Should the generated `cli` type have a `Value`
|
||||
member?
|
||||
dest (bool) - Should the generated `cli` type support a
|
||||
destination pointer?
|
||||
doctail (string) - Additional docs for the `cli` flag type comment
|
||||
context_type (string) - The literal type used in the `*cli.Context`
|
||||
reader func signature
|
||||
context_default (string) - The literal value used as the default by the
|
||||
`*cli.Context` reader funcs when no value is
|
||||
present
|
||||
parser (string) - Literal code used to parse the flag `f`,
|
||||
expected to have a return signature of
|
||||
(value, error)
|
||||
parser_cast (string) - Literal code used to cast the `parsed` value
|
||||
returned from the `parser` code
