Multi-line strings don't work on Windows #254
Description
Original error
I recently tried to use a new version of Gren (previously on 0.2.0) and was unuable to get it to compile. As a result I tried just doing a simple project with default dependencies.
My gren.json (created by gren init) is below:
{
"type": "application",
"platform": "browser",
"source-directories": [
"src"
],
"gren-version": "0.4.4",
"dependencies": {
"direct": {
"gren-lang/browser": "4.0.0",
"gren-lang/core": "5.0.2"
},
"indirect": {
"gren-lang/url": "4.0.0"
}
}
}
and it results in this error:
Dependency problem!
-- PROBLEM BUILDING DEPENDENCIES -----------------------------------------------
I ran into a compilation error when trying to build the following package:
gren-lang/browser 4.0.0
This probably means it has package constraints that are too wide. It may be
possible to tweak your gren.json to avoid the root problem as a stopgap. Head
over to https://gren-lang.org/community to get help figuring out how to take
this path!
Note: To help with the root problem, please report this to the package author
along with the following information:
gren-lang/core 5.0.2
gren-lang/url 4.0.0
If you want to help out even more, try building the package locally. That should
give you much more specific information about why this package is failing to
build, which will in turn make it easier for the package author to fix it!
Actually it looks like the error is that Git on Windows likes changing line endings to \r\n rather than just \n and Gren doesn't like that with multiline strings:
AppData\Local\gren\0.4.4\packages\gren-lang\browser\4.0.0
> gren make

My system git has core.autocrlf set to true, but everything else is generally happy.
