When I try to lint content, and it generate incorrect span range
✅ English characters:
const { Biome, Distribution } = require('@biomejs/js-api')
async function main() {
const biome = await Biome.create({
distribution: Distribution.NODE
})
const input = '/** English comment */ let a = 123'
const result = biome.lintContent(input, { filePath: 'index.js' })
for (const diagnostic of result.diagnostics) {
const [start, end] = diagnostic.location.span
const span = input.slice(start, end)
console.log('start -->', start, 'end -->', end, 'span -->', span)
// start --> 23 end --> 26 span --> let
}
}
main()❌ Chinese characters:
const { Biome, Distribution } = require('@biomejs/js-api')
async function main() {
const biome = await Biome.create({
distribution: Distribution.NODE
})
const input = '/** 中文注释 */ let a = 123'
const result = biome.lintContent(input, { filePath: 'index.js' })
for (const diagnostic of result.diagnostics) {
const [start, end] = diagnostic.location.span
const span = input.slice(start, end)
console.log('start -->', start, 'end -->', end, 'span -->', span)
// start --> 20 end --> 23 span --> 123
}
}
main()❌ Japanese characters:
const { Biome, Distribution } = require('@biomejs/js-api')
async function main() {
const biome = await Biome.create({
distribution: Distribution.NODE
})
const input = '/** 日本語注釈 */ let a = 123'
const result = biome.lintContent(input, { filePath: 'index.js' })
for (const diagnostic of result.diagnostics) {
const [start, end] = diagnostic.location.span
const span = input.slice(start, end)
console.log('start -->', start, 'end -->', end, 'span -->', span)
// start --> 23 end --> 26 span --> 3
}
}
main()Expected result
The output span is incorrect
