Css-loader: Where is documentation for [path], [name] and [local] variables?

[gajus]

Documentation (https://github.com/webpack/css-loader#local-scope) mentions these variables in one of the examples:

You can configure the generated ident with the localIdentName query parameter (default [hash:base64]). Example: css-loader?localIdentName=[path][name]---[local]---[hash:base64:5] for easier debugging.

I cannot find more documentation. Specifically what variables are available aside from [path], [name] and [local]?

I have looked into extract-text-webpack-plugin documentation and it only mentions (https://github.com/webpack/extract-text-webpack-plugin#api):

filename the filename of the result file. May contain [name], [id] and [contenthash].

• [name] the name of the chunk
• [id] the number of the chunk
• [contenthash] a hash of the content of the extracted file

Was looking up for the same info, found this: https://github.com/webpack/loader-utils/blob/master/index.js#L197

It seems that ext, name, path and hash are the only tokens available. Then, there is the regExp thingy but I don't know yet how to use it.

[gajus]

@qur2 always include commit or a tag when referring to the source code, e.g. https://github.com/webpack/loader-utils/blob/v0.2.12/index.js#L197

Otherwise link becomes historically useless as soon as any changes have been made to that file.

Alright, that makes sense, thanks for the advice.

From duped issue:

[name]
[local]
[path]
[hash:base64:5]
folder
ext
emoji:XXXX

[michael-ciniawsky]

loader-utils repo and/or hopefully on webpack.js.org :)

So is there a place in the documentation that covers these?

Copied from https://github.com/webpack/loader-utils:

The following tokens are replaced in the name parameter:

• [ext] the extension of the resource
• [name] the basename of the resource
• [path] the path of the resource relative to the context query parameter or option.
• [folder] the folder of the resource is in.
• [emoji] a random emoji representation of options.content
• [emoji:<length>] same as above, but with a customizable number of emojis
• [hash] the hash of options.content (Buffer) (by default it's the hex digest of the md5 hash)
• [<hashType>:hash:<digestType>:<length>] optionally one can configure
  
  
  
  • other hashTypes, i. e. sha1, md5, sha256, sha512
  
  
  • other digestTypes, i. e. hex, base26, base32, base36, base49, base52, base58, base62, base64
  
  
  • and length the length in chars
  
  
• [N] the N-th match obtained from matching the current file name against options.regExp
