From ce18c948e620b658c19200d6875202877b2691a4 Mon Sep 17 00:00:00 2001 From: ValdikSS Date: Fri, 22 Apr 2022 02:00:57 +0300 Subject: [PATCH] Do not apply any markup to URL entities (telegram) (#1808) handleEntities code uses simple modification offset which does not allow to detect whether the offset is placed before or after the element in already modified string. This works fine is most cases as Telegram server always sort the elements by offset, in ascending order. However, this is not the case when the modification, for example bold text, is applied to the URL. In this case, the offset of URL and bold entity is equal, which raises the issue. This commit introduces additional hack for this case, stripping any entities which intersect with URL. --- bridge/telegram/handlers.go | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/bridge/telegram/handlers.go b/bridge/telegram/handlers.go index adf291dc..985db7f9 100644 --- a/bridge/telegram/handlers.go +++ b/bridge/telegram/handlers.go @@ -517,8 +517,8 @@ func (b *Btelegram) handleEntities(rmsg *config.Message, message *tgbotapi.Messa } indexMovedBy := 0 + prevLinkOffset := -1 - // for now only do URL replacements for _, e := range message.Entities { asRunes := utf16.Encode([]rune(rmsg.Text)) @@ -537,6 +537,11 @@ func (b *Btelegram) handleEntities(rmsg *config.Message, message *tgbotapi.Messa } rmsg.Text = string(utf16.Decode(asRunes[:offset+e.Length])) + " (" + url.String() + ")" + string(utf16.Decode(asRunes[offset+e.Length:])) indexMovedBy += len(url.String()) + 3 + prevLinkOffset = e.Offset + } + + if e.Offset == prevLinkOffset { + continue } if e.Type == "code" {
