Functions ¶
func Bool ¶
func Bool(x interface{}) bool
Bool returns the interface value if it is a bool, and otherwise it panics.
func BoolMapTrue ¶
BoolMapTrue returns true if everyone in the list is true.
func BoolMapValues ¶
BoolMapValues returns the sorted list of bool values in a map with string values.
func CopyDiskToFs ¶
CopyDiskToFs performs exactly as CopyFs, except that the src fs is our local disk os fs.
func CopyFs ¶
CopyFs copies a dir from the srcFs to a dir on the dstFs. It expects that the dst will be either empty, or that the force flag will be set to true. If the dst has a different set of contents in the same location, the behaviour is currently undefined. TODO: this should be made more rsync like and robust!
func CopyFsToDisk ¶
CopyFsToDisk performs exactly as CopyFs, except that the dst fs is our local disk os fs.
func DirifyFileList ¶
DirifyFileList adds trailing slashes to any likely dirs in a package manager fileList if removeDirs is true, otherwise, don't keep the dirs in our output.
func FirstToUpper ¶
FirstToUpper returns the string with the first character capitalized.
func FlattenListWithSplit ¶
FlattenListWithSplit flattens a list of input by splitting each element by any and all of the strings listed in the split array
func FsTree ¶
FsTree returns a string representation of the file system tree similar to the well-known `tree` command.
func HasPathPrefix ¶
HasPathPrefix tells us if a path string contain the given path prefix in it.
func NumToAlpha ¶
NumToAlpha returns a lower case string of letters representing a number. If you specify 0, you'll get `a`, 25 gives you `z`, and 26 gives you `aa` and so on...
func PathPrefixDelta ¶
PathPrefixDelta returns the delta of the path prefix, which tells you how many path tokens different the prefix is.
func PathSplit ¶
PathSplit splits a path into an array of tokens excluding any trailing empty tokens.
func PathSplitFullReversed ¶
PathSplitFullReversed returns the full list of "dependency" paths for a given path in reverse order.
func RemoveCommonFilePrefixes ¶
RemoveCommonFilePrefixes removes redundant file path prefixes that are under the tree of other files.
func ReverseStringList ¶
ReverseStringList reverses a list of strings.
func StrFilterElementsInList ¶
StrFilterElementsInList removes any of the elements in filter, if they exist in the list.
func StrInPathPrefixList ¶
StrInPathPrefixList returns true if the needle is a PathPrefix in the haystack.
func StrListIntersection ¶
StrListIntersection removes any of the elements in filter, if they don't exist in the list. This is an in order intersection of two lists.
func StrMapKeys ¶
StrMapKeys return the sorted list of string keys in a map with string keys. NOTE: i thought it would be nice for this to use: map[string]interface{} but it turns out that's not allowed. I know we don't have generics, but come on!
func StrMapKeysUint64 ¶
StrMapKeysUint64 return the sorted list of string keys in a map with string keys but uint64 values.
func StrMapValues ¶
StrMapValues returns the sorted list of string values in a map with string values.
func StrMapValuesUint64 ¶
StrMapValuesUint64 return the sorted list of string values in a map with string values.
func StrRemoveDuplicatesInList ¶
StrRemoveDuplicatesInList removes any duplicate values in the list. This implementation is possibly sub-optimal (O(n^2)?) but preserves ordering.
func SystemBusPrivateUsable ¶
SystemBusPrivateUsable makes using the private bus usable TODO: should be upstream: https://github.com/godbus/dbus/issues/15
func TimeAfterOrBlock ¶
TimeAfterOrBlock is aspecial version of time.After that blocks when given a negative integer. When used in a case statement, the timer restarts on each select call to it.
