chainsmoker
Elegant, generically typed, boolean micromatch for lists of file paths in TypeScript.
- Works with CommonJS and ES Modules, too.
- Safer and more concise than using
.filter()
and.length
. - Designed for concise syntax in dangerfiles but not tied to them in any way.
I'm pleased to say as of Danger.js 7.1, this helper is vendored into
Danger and accessible as danger.fileMatch
.
Usage
const { danger, fail, message, warn } = require('danger')
const chainsmoker = require('chainsmoker')
// In this example, these are all arrays of relative paths.
const fileMatch = chainsmoker({
created: danger.git.created_files,
modified: danger.git.modified_files,
updated: danger.git.modified_files.concat(danger.git.created_files),
deleted: danger.git.deleted_files,
})
const documentation = fileMatch(
'**/*.md',
'lib/all-badge-examples.js',
'frontend/components/usage.js'
)
const packageJson = fileMatch('package.json')
const packageLock = fileMatch('package-lock.json')
const helpers = fileMatch('lib/**/*.js', '!**.spec.js')
const helperTests = fileMatch('lib/**/*.spec.js')
// This is `true` whenever there are matches in the corresponding path array.
if (documentation.updated) {
message('We :heart: our [documentarians](http://www.writethedocs.org/)!')
}
if (packageJson.modified && !packageLock.modified) {
warn('This PR modified package.json, but not package-lock.json')
}
if (helpers.created && !helperTests.created) {
warn('This PR added helper modules in lib/ but not accompanying tests.')
} else if (helpers.updated && !helperTests.updated) {
warn('This PR modified helper modules in lib/ but not accompanying tests.')
}
fileMatch.getKeyedPatterns()
Return an object containing arrays of matched files instead of the usual boolean values.

The name :smoking:
The name was inspired by the idea of a chainable file-set object using minimatch. It's also for Danger… maybe that was part of the inspiration.
I ended up with something simpler that doesn't rely on chaining, though I kept the name.
