# 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, sex characteristics, 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 the project team at vasile.gabriel@email.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.
|
||||
|
||||

## Features
|
||||
- fast and precise MIME type and file extension detection
|
||||
- long list of [supported MIME types](supported_mimes.md)
|
||||
- possibility to [extend](https://pkg.go.dev/github.com/gabriel-vasile/mimetype#example-package-Extend) with other file formats
|
||||
- common file formats are prioritized
|
||||
- [text vs. binary files differentiation](https://pkg.go.dev/github.com/gabriel-vasile/mimetype#example-package-TextVsBinary)
|
||||
- safe for concurrent usage
|
||||
|
||||
## Install
|
||||
```bash
|
||||
go get github.com/gabriel-vasile/mimetype
|
||||
```
|
||||
|
||||
## Usage
|
||||
```go
|
||||
mtype := mimetype.Detect([]byte)
|
||||
// OR
|
||||
mtype, err := mimetype.DetectReader(io.Reader)
|
||||
// OR
|
||||
mtype, err := mimetype.DetectFile("/path/to/file")
|
||||
fmt.Println(mtype.String(), mtype.Extension())
|
||||
```
|
||||
See the [runnable Go Playground examples](https://pkg.go.dev/github.com/gabriel-vasile/mimetype#pkg-overview).
|
||||
|
||||
## Usage'
|
||||
Only use libraries like **mimetype** as a last resort. Content type detection
|
||||
using magic numbers is slow, inaccurate, and non-standard. Most of the times
|
||||
protocols have methods for specifying such metadata; e.g., `Content-Type` header
|
||||
in HTTP and SMTP.
|
||||
|
||||
## FAQ
|
||||
Q: My file is in the list of [supported MIME types](supported_mimes.md) but
|
||||
it is not correctly detected. What should I do?
|
||||
|
||||
A: Some file formats (often Microsoft Office documents) keep their signatures
|
||||
towards the end of the file. Try increasing the number of bytes used for detection
|
||||
with:
|
||||
```go
|
||||
mimetype.SetLimit(1024*1024) // Set limit to 1MB.
|
||||
// or
|
||||
mimetype.SetLimit(0) // No limit, whole file content used.
|
||||
mimetype.DetectFile("file.doc")
|
||||
```
|
||||
If increasing the limit does not help, please
|
||||
[open an issue](https://github.com/gabriel-vasile/mimetype/issues/new?assignees=&labels=&template=mismatched-mime-type-detected.md&title=).
|
||||
|
||||
## Structure
|
||||
**mimetype** uses a hierarchical structure to keep the MIME type detection logic.
|
||||
This reduces the number of calls needed for detecting the file type. The reason
|
||||
behind this choice is that there are file formats used as containers for other
|
||||
file formats. For example, Microsoft Office files are just zip archives,
|
||||
containing specific metadata files. Once a file has been identified as a
|
||||
zip, there is no need to check if it is a text file, but it is worth checking if
|
||||
it is an Microsoft Office file.
|
||||
|
||||
To prevent loading entire files into memory, when detecting from a
|
||||
[reader](https://pkg.go.dev/github.com/gabriel-vasile/mimetype#DetectReader)
|
||||
or from a [file](https://pkg.go.dev/github.com/gabriel-vasile/mimetype#DetectFile)
|
||||
**mimetype** limits itself to reading only the header of the input.
|
||||
<div align="center">
|
||||
<img alt="structure" src="https://github.com/gabriel-vasile/mimetype/blob/420a05228c6a6efbb6e6f080168a25663414ff36/mimetype.gif?raw=true" width="88%">
|
||||
</div>
|
||||
|
||||
## Performance
|
||||
Thanks to the hierarchical structure, searching for common formats first,
|
||||
and limiting itself to file headers, **mimetype** matches the performance of
|
||||
stdlib `http.DetectContentType` while outperforming the alternative package.
|
||||
|
||||
```bash
|
||||
mimetype http.DetectContentType filetype

In May 2003, two Internet RFCs were published relating to the format.

The Ogg bitstream was defined in RFC 3533 (which is classified as

'informative') and its Internet content type (application/ogg) in RFC

3534 (which is, as of 2006, a proposed standard protocol). In

September 2008, RFC 3534 was obsoleted by RFC 5334, which added

content types video/ogg, audio/ogg and filename extensions .ogx, .ogv,

.oga, .spx.
