# 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.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

## 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>
## 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.
