# less-relative-urls-bug
This repository demonstrates a bug in [Less](https://github.com/less/less.js) when the content is passed via stdin and the `--relative-urls` option is used.
---
Run `npm run error` to reproduce the problem:
```bash
> [email protected] error /Users/jhnns/dev/temp/less-relative-urls-bug
> cd ./a/a && ../../node_modules/.bin/lessc -ru - < a.less
.b {
background-image: url("b/b/test.jpg");
}
```
The expected output would be:
```bash
.b {
background-image: url("../../b/b/test.jpg");
}
```
---
When the folder is nested only one level deep, however, the output is correct. See `npm run ok`:
```bash
> [email protected] ok /Users/jhnns/dev/temp/less-relative-urls-bug
> cd ./a && ../node_modules/.bin/lessc -ru - < a.less
.b {
background-image: url("../b/b/test.jpg");
}
```
---
The problem is [somewhere along these lines](https://github.com/less/less.js/blob/43ab0b872248ec34186bd8c245904d9a0f5d7825/lib/less/import-manager.js#L89-L97) and can be reproduced with less `2.x` and `[email protected]`. `alpha.2` is throwing an error:
```
