Update usage and import paths with and without package management.
Document the dep transitive dependency issue and how to get around it.
Couple more minor edits.
The goal of this change is to reduce number of non-standard library
packages (repositories) that blackfriday imports from 1 to 0, and in
turn, reduce the cost of importing blackfriday into other projects.
Do so by documenting the algorithm of SanitizedAnchorName, and include
a copy of the small function inside blackfriday itself. The same
functionality continues to be available in the original location,
github.com/shurcooL/sanitized_anchor_name.Create. It can be used by
existing users and those that look for a small package, and don't need
all of blackfriday functionality. Existing users of blackfriday can use
the new SanitizedAnchorName function directly and avoid an extra
package import.
Resolves#350.
Also make tip a fast-finish allowed failure. That way, if CI fails on
tip due to a temporary issue with tip, it will not break build status.
However, it's still possible to see tip build status by looking at CI
details page.
Do not run go vet with Go 1.4 or older since it's not included in the
standard library, and it's no longer available in external standard
library.
Add godoc badge to README.md.
The original upskirt library by Natacha Porté has been renamed to
libsoldout, while the fork of it that was located at tanoku/upskirt has
been renamed to Sundown and moved to vmg/sundown. Since Blackfriday has
been started as a translation of tanoku/upskirt, rename its mention in
README to Sundown.
It's pretty standard to have a license file, and some projects require
them before your code can be used in their code. Move the license to
its own file.
Apply gofmt on html.go.
Apply goimports-compatible formatting on block.go (space between standard and third party imports).
Move Travis build status image in a more pleasing, common location.
Remove "Markdown pretty-printer output engine" from TODO steps; this is already done in markdownfmt.
Remove unneeded trailing whitespace in README.
