write to a separate source map file from CLI

[jonathanong]

right now, you can only inline source maps. any way to allow separate source map files?

Is this enough for you ?

[jonathanong]

sorry. needed to be more specific. i'm currently trying via CLI w/ the watcher. trying to avoid a custom node.js script :)

Hum so I think I've done nothing yet. Maybe we should handle #73 to allow options from json ?

[MoOx]

Maybe you can check if --config can help you (you can provide a .js config)...
Hum it seems -map option doesn't exist yet. Should not be that hard to add around here https://github.com/cssnext/cssnext/blob/62aeafb32a8d8f50a655152486bad0bac65e25b4/bin/cssnext.js#L72
PRs are welcome :)

yeah was looking into the config. i can add .map option to the config, but the source map is still not saved because it needs to be handled by the CLI.

how would you want the option to look like? --map [filename]? where filename is optional, and if it does not exist, inline like normally?

[MoOx]

--sourcemap is already inlining normally, so I guess if you use --map you must provide a filename. But yeah we can do that :) That should enable as well map entry in config file from wat I see in the code (I did not create the --config option).

Not relevant anymore. cssnext is now postcss-cssnext. cssnext is deprecated. See postcss-cssnext migration guide http://cssnext.io/postcss/
