From c84630714405a1e93766a6a6c023801302a3ea66 Mon Sep 17 00:00:00 2001 From: Reto Brunner Date: Wed, 19 Aug 2020 12:01:45 +0200 Subject: base models.Address on the mail.Address type This allows us to hook into the std libs implementation of parsing related stuff. For this, we need to get rid of the distinction between a mailbox and a host to just a single "address" field. However this is already the common case. All but one users immediately concatenated the mbox/domain to a single address. So this in effects makes it simpler for most cases and we simply do the transformation in the special case. --- commands/msg/forward.go | 3 ++- lib/format/format.go | 60 ++++++++++++++++++++++++++++++++++++------------- models/models.go | 34 +++++++++------------------- widgets/msgviewer.go | 15 +++++++------ worker/imap/imap.go | 3 +-- worker/lib/parse.go | 11 +-------- worker/lib/sort.go | 3 +-- 7 files changed, 67 insertions(+), 62 deletions(-) diff --git a/commands/msg/forward.go b/commands/msg/forward.go index 3ff0194f..0c6b0e05 100644 --- a/commands/msg/forward.go +++ b/commands/msg/forward.go @@ -11,6 +11,7 @@ import ( "strings" "git.sr.ht/~sircmpwn/aerc/lib" + "git.sr.ht/~sircmpwn/aerc/lib/format" "git.sr.ht/~sircmpwn/aerc/models" "git.sr.ht/~sircmpwn/aerc/widgets" "git.sr.ht/~sircmpwn/aerc/worker/types" @@ -77,7 +78,7 @@ func (forward) Execute(aerc *widgets.Aerc, args []string) error { addTab := func() (*widgets.Composer, error) { if template != "" { - original.From = models.FormatAddresses(msg.Envelope.From) + original.From = format.FormatAddresses(msg.Envelope.From) original.Date = msg.Envelope.Date } diff --git a/lib/format/format.go b/lib/format/format.go index cc46da8c..06b4d3f5 100644 --- a/lib/format/format.go +++ b/lib/format/format.go @@ -2,22 +2,46 @@ package format import ( "errors" - "fmt" + "mime" gomail "net/mail" "strings" "time" "unicode" "git.sr.ht/~sircmpwn/aerc/models" + "github.com/emersion/go-message" ) -func parseAddress(address string) *gomail.Address { +func ParseAddress(address string) (*models.Address, error) { addrs, err := gomail.ParseAddress(address) if err != nil { - return nil + return nil, err + } + return (*models.Address)(addrs), nil +} + +func ParseAddressList(s string) ([]*models.Address, error) { + parser := gomail.AddressParser{ + &mime.WordDecoder{message.CharsetReader}, + } + list, err := parser.ParseList(s) + if err != nil { + return nil, err } - return addrs + addrs := make([]*models.Address, len(list)) + for i, a := range list { + addrs[i] = (*models.Address)(a) + } + return addrs, nil +} + +func FormatAddresses(l []*models.Address) string { + formatted := make([]string, len(l)) + for i, a := range l { + formatted[i] = a.Format() + } + return strings.Join(formatted, ", ") } func ParseMessageFormat( @@ -29,7 +53,10 @@ func ParseMessageFormat( retval := make([]byte, 0, len(format)) var args []interface{} - accountFromAddress := parseAddress(fromAddress) + accountFromAddress, err := ParseAddress(fromAddress) + if err != nil { + return "", nil, err + } var c rune for i, ni := 0, 0;
