Capitalize does foo => Foo, BAR => Bar etc.

CloseNoError is like io.Closer Close() but ignores an error use as: defer CloseNoError(f).

CopyFile copies a file from src to dst It'll create destination directory if necessary.

toZip is a list of files and directories in baseDir Directories are added recursively.

CreateZipWithDirContent creates a zip file with the content of a directory.

DirExists returns true if path exists and is a directory.

ExtEqualFold returns true if s ends with extension (e.g.

FileExists returns true if path exists and is a regular file.

FileLineCount returns number of lines in a file.

FileSize gets file size, -1 if file doesn't exist.

Formats duration in a more human friendly way than time.Duration.String().

FormatSize formats a number in a human-readable form e.g.

call cb on each file in a directory.

call cb on each file in fsys startDir should be ".

NewLineStats returns new LineStats.

NormalizeNewlines is like NormalizeNewlinesInPlace but slower because it makes a copy of data.

NormalizeNewlinesInPlace changes CRLF (Windows) and CR (Mac) to LF (Unix) Optimized for speed, modifies data in place.

OpenFileMaybeCompressed opens a file that might be compressed with gzip or bzip2 or zstd or brotli TODO: could sniff file content instead of checking file extension.

PathExists returns true if path exists.

PathIsDir returns true if a path exists and is a directory Returns false, nil if a path exists and is not a directory (e.g.

Percent returns how many percent of total is sub 100% means total == sub, 50% means sub = total / 2.

ReadFileMaybeCompressed reads file.

ReadLines reads file as lines.

ReadLinesFromReader reads lines from io.Reader.

Slug generates safe url from string by removing hazardous characters.

TrimExt removes extension from s.

TrimPrefix is like strings.TrimPrefix but also returns a bool indicating that the string was trimmed.

WriteFileGzipped writes data to a path, using best gzip compression.

LineCount describes line count for a file.

LineStats gathers line count info for files.

MemoryFS is a custom file system that uses a map to store file data.

time.Duration with a better string representation.
