Input:
{{{
@import '../../3rdparty/pt-sans-generated/stylesheet.css';
html, body {
padding: 0;
margin: 0;
background: transparent;
}
}}}
Output:
{{{
url("../../3rdparty/pt-sans-generated/stylesheet.cc11c6fa559e.css");
html, body {
padding: 0;
margin: 0;
background: transparent;
}
}}}
Without @import statement!
Problem located in:
{{{
class CachedFilesMixin(object):
patterns = (
("*.css", (
r"""(url\(['"]{0,1}\s*(.*?)["']{0,1}\))""",
r"""(@import\s*["']\s*(.*?)["'])""",
)),
)
}}}
last statement replace whole (@import…) construction with just url(). This
quick fix solves a problem:
{{{
class FixedCachedFilesMixin(CachedFilesMixin):
patterns = (
("*.css", (
r"""(url\(['"]{0,1}\s*(.*?)["']{0,1}\))""",
r"""@import\s*(["']\s*(.*?)["'])""",
)),
)
class CachedStaticFilesStorage(CachedFilesMixin, StaticFilesStorage):
"""
A static file system storage backend which also saves
hashed copies of the files it saves.
"""
pass
}}}
But it is definitely a serious bug because @import is completely broken by
default.
