From e56ceb099e23cf170750758c67f00713bff1cce1 Mon Sep 17 00:00:00 2001 From: Clayton Craft Date: Tue, 11 Jun 2019 11:26:13 -0700 Subject: Support directories in path to :save This adds new functionality to :save in the message view for specifying directories in the path. A new flag, -p, is also added to :save for automatically creating any directories in the path that do not exist. If the path ends in a / (e.g. "Downloads/mail/") or if the path is an existing directory, the part's file name is the filename from the mail header for the part. Otherwise, it uses the last element in the path as the filename (e.g. 'blah.jpg' is the filename if the path is 'Downloads/mail/blah.jpg') --- commands/msgview/save.go | 57 ++++++++++++++++++++++++++++++++++++++++++++---- doc/aerc.1.scd | 4 +++- 2 files changed, 56 insertions(+), 5 deletions(-) diff --git a/commands/msgview/save.go b/commands/msgview/save.go index 4dabd52..b15f42d 100644 --- a/commands/msgview/save.go +++ b/commands/msgview/save.go @@ -6,9 +6,11 @@ import ( "io" "mime/quotedprintable" "os" + "path/filepath" "time" "git.sr.ht/~sircmpwn/aerc/widgets" + "git.sr.ht/~sircmpwn/getopt" "github.com/mitchellh/go-homedir" ) @@ -17,9 +19,24 @@ func init() { } func Save(aerc *widgets.Aerc, args []string) error { - if len(args) < 2 { - return errors.New("Usage: :save ") + opts, optind, err := getopt.Getopts(args, "p") + if err != nil { + return err } + var ( + mkdirs bool + path string + ) + for _, opt := range opts { + switch opt.Option { + case 'p': + mkdirs = true + } + } + if len(args) <= optind { + return errors.New("Usage: :save [-p] ") + } + path = args[optind] mv := aerc.SelectedTab().(*widgets.MessageViewer) p := mv.CurrentPart() @@ -33,12 +50,44 @@ func Save(aerc *widgets.Aerc, args []string) error { reader = quotedprintable.NewReader(reader) } - target, err := homedir.Expand(args[1]) + var pathIsDir bool + if path[len(path)-1:] == "/" { + pathIsDir = true + } + // Note: path expansion has to happen after test for trailing /, + // since it is stripped when path is expanded + path, err := homedir.Expand(path) if err != nil { aerc.PushError(" " + err.Error()) - return } + pathinfo, err := os.Stat(path) + if err == nil && pathinfo.IsDir() { + pathIsDir = true + } else if os.IsExist(err) && pathIsDir { + aerc.PushError("The given directory is an existing file") + } + + // Use attachment name as filename if given path is a directory + save_file := filepath.Base(path) + save_dir := filepath.Dir(path) + if pathIsDir { + save_dir = path + if filename, ok := p.Part.DispositionParams["filename"]; ok { + save_file = filename + } + } + if _, err := os.Stat(save_dir); os.IsNotExist(err) { + if mkdirs { + os.MkdirAll(save_dir, 0755) + } else { + aerc.PushError("Target directory does not exist, use " + + ":save with the -p option to create it") + return + } + } + target := filepath.Clean(filepath.Join(save_dir, save_file)) + f, err := os.Create(target) if err != nil { aerc.PushError(" " + err.Error()) diff --git a/doc/aerc.1.scd b/doc/aerc.1.scd index 229868f..7b09531 100644 --- a/doc/aerc.1.scd +++ b/doc/aerc.1.scd @@ -119,9 +119,11 @@ message list, the message in the message viewer, etc).
