I wanted to shorten my configuration file a bit. I have a long configuration for flexget with entries like that:
yt_tech-talk-today: rss: http://feedpress.me/t3mob template: youtube I can replace that with such let statement: ${let makeFeed = { name, url}: { x = " yt_$name:\n rss: $url\n template: youtube";}.x; in makeFeed { name = "tech-talk-today"; url = "http://feedpress.me/t3mob"; } } but now I wanted to use the map function to map more than one entry like that: ${let makeFeed = { name, url}: { x = " yt_$name:\n rss: $url\n template: youtube";}.x; in map makeFeed [ { name = "tech-talk-today"; url = "http://feedpress.me/t3mob"; }] } which did not work cause it generates a list of strings what it cant "coerce" to a string: error: cannot coerce a list to a string Now I thought there is maybe some sort of concat function or merge function to build out of this list ONE stirng so it works. Either this api is very limited or not very well documented, some github nix packages seem to imply or list a concat function, but it seems to not work or I dont understand this language very well. wrapping that in a ${concat { let... } at least seems to not work, any suggestions? _______________________________________________ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
