1+# Contributor Covenant Code of Conduct
2+
3+## Our Pledge
4+
5+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, nationality, personal appearance, race, religion, or sexual identity and orientation.
6+
7+## Our Standards
8+
9+Examples of behavior that contributes to creating a positive environment include:
10+* Using welcoming and inclusive language
11+* Being respectful of differing viewpoints and experiences
12+* Gracefully accepting constructive criticism
13+* Focusing on what is best for the community
14+* Showing empathy towards other community members
15+
16+Examples of unacceptable behavior by participants include:
17+
18+* The use of sexualized language or imagery and unwelcome sexual attention or advances
19+* Trolling, insulting/derogatory comments, and personal or political attacks
20+* Public or private harassment
21+* Publishing others' private information, such as a physical or electronic address, without explicit permission
22+* Other conduct which could reasonably be considered inappropriate in a professional setting
23+
24+## Our Responsibilities
25+
26+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.
27+
28+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.
29+
30+## Scope
31+
32+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.
33+
34+## Enforcement
35+
36+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by [contacting the project team at m@jaspervdj.be](mailto:m@jaspervdj.be). 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.
37+
38+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.
39+

19+-- | This function exposes a higher-level interface compared to using the
20+-- 'Redirect' type manually.
21+--
22+-- This creates, using a database mapping broken URLs to working ones, HTML
23+-- files which will do HTML META tag redirect pages (since, as a static site, we
24+-- can't use web-server-level 301 redirects, and using JS is gross).
25+--
26+-- This is useful for sending people using old URLs to renamed versions, dealing
27+-- with common typos etc, and will increase site traffic. Such broken URLs can
28+-- be found by looking at server logs or by using Google Webmaster Tools.
29+-- Broken URLs must be valid Haskell strings, non-URL-escaped valid POSIX
30+-- filenames, and relative links, since they will be defined in a @hakyll.hs@
31+-- and during generation, written to disk with the filename corresponding to the
32+-- broken URLs. (Target URLs can be absolute or relative, but should be
33+-- URL-escaped.) So broken incoming links like <http://www.gwern.net/foo/> which
34+-- should be <http://www.gwern.net/foobar> cannot be fixed (since you cannot
35+-- create a HTML file named @"foo/"@ on disk, as that would be a directory).
36+--
37+-- An example of a valid association list would be:
38+--
39+-- > brokenLinks =
40+-- > [ ("projects.html", "http://github.com/gwern")
41+-- > , ("/Black-market archive", "Black-market%20archives")
42+-- > ]
43+--
44+-- In which case the functionality can then be used in `main` with a line like:
45+--
46+-- > version "redirects" $ createRedirects brokenLinks
47+--
48+-- The 'version' is recommended to separate these items from your other pages.
49+--
50+-- The on-disk files can then be uploaded with HTML mimetypes
51+-- (either explicitly by generating and uploading them separately, by
52+-- auto-detection of the filetype, or an upload tool defaulting to HTML
53+-- mimetype, such as calling @s3cmd@ with @--default-mime-type=text/html@) and
54+-- will redirect browsers and search engines going to the old/broken URLs.
55+--
56+-- See also <https://groups.google.com/d/msg/hakyll/sWc6zxfh-uM/fUpZPsFNDgAJ>.
