From 7dd5e0fc8ec6659d27918857f183977726631dcf Mon Sep 17 00:00:00 2001 From: Tusooa Zhu Date: Tue, 10 Aug 2021 23:58:27 -0400 Subject: [PATCH] Implement Misskey-style tree view Now the tree will be always rooted at the highlighted status, and all its ancestors shown linearly on the top. Enhancement: If an ancestor has more than one reply (i.e. it has a child that is not on current status's ancestor chain), we are given a link to root the thread at that status. --- src/components/conversation/conversation.js | 61 +++++----- src/components/conversation/conversation.vue | 118 +++++++++++++++---- 2 files changed, 124 insertions(+), 55 deletions(-) diff --git a/src/components/conversation/conversation.js b/src/components/conversation/conversation.js index bd8315b8..817b9bda 100644 --- a/src/components/conversation/conversation.js +++ b/src/components/conversation/conversation.js @@ -55,7 +55,7 @@ const conversation = { expanded: false, threadDisplayStatusObject: {}, // id => 'showing' | 'hidden' statusContentPropertiesObject: {}, - diveHistory: [] + inlineDivePosition: null } }, props: [ @@ -231,7 +231,10 @@ const conversation = { return this.topLevel }, diveRoot () { - return this.diveHistory[this.diveHistory.length - 1] + (() => {})(this.conversation) + const statusId = this.inlineDivePosition || this.statusId + const isTopLevel = !this.parentOf(statusId) + return isTopLevel ? null : statusId }, diveDepth () { return this.canDive && this.diveRoot ? this.depths[this.diveRoot] : 0 @@ -332,7 +335,6 @@ const conversation = { this.fetchConversation() } else { // if we collapse it, we should reset the dive - this._diven = false this.undive() } }, @@ -348,19 +350,6 @@ const conversation = { if (!this.isExpanded) { return } - - if (!this._diven) { - if (!this.threadDisplayStatus[this.statusId]) { - return - } - this._diven = true - const parentOrSelf = this.parentOrSelf(this.originalStatusId) - // If current status is not visible - if (this.threadDisplayStatus[parentOrSelf] === 'hidden') { - this.diveIntoStatus(parentOrSelf, /* preventScroll */ true) - this.tryScrollTo(this.statusId) - } - } }, fetchConversation () { if (this.status) { @@ -449,26 +438,15 @@ const conversation = { return this.topLevel[0] ? this.topLevel[0].id : undefined }, diveIntoStatus (id, preventScroll) { - this.diveHistory = [...this.diveHistory, id] - if (!preventScroll) { - this.goToCurrent() - } + this.tryScrollTo(id) }, - diveBack () { - const oldHighlight = this.highlight - this.diveHistory = [...this.diveHistory.slice(0, this.diveHistory.length - 1)] - if (oldHighlight) { - this.tryScrollTo(this.leastVisibleAncestor(oldHighlight)) - } + diveToTopLevel () { + this.tryScrollTo(this.topLevel[0].id) }, + // only used when we are not on a page undive () { - const oldHighlight = this.highlight - this.diveHistory = [] - if (oldHighlight) { - this.tryScrollTo(this.leastVisibleAncestor(oldHighlight)) - } else { - this.goToCurrent() - } + this.inlineDivePosition = null + this.setHighlight(this.statusId) }, tryScrollTo (id) { if (!id) { @@ -477,8 +455,9 @@ const conversation = { if (this.isPage) { // set statusId this.$router.push({ name: 'conversation', params: { id } }) + } else { + this.inlineDivePosition = id } - this.setHighlight(id) }, goToCurrent () { @@ -493,10 +472,24 @@ const conversation = { return undefined } const { in_reply_to_status_id: parentId } = status + if (!this.statusMap[parentId]) { + return undefined + } return parentId }, parentOrSelf (id) { return this.parentOf(id) || id + }, + // Ancestors of some status, from top to bottom + ancestorsOf (id) { + const ancestors = [] + let cur = this.parentOf(id) + while (cur) { + ancestors.unshift(this.statusMap[cur]) + cur = this.parentOf(cur) + } + // console.log('ancestors = ', ancestors, 'conversation = ', this.conversation.map(k => k.id), 'statusContentProperties=', this.statusContentProperties) + return ancestors } } } diff --git a/src/components/conversation/conversation.vue b/src/components/conversation/conversation.vue index c866b983..20ce54a6 100644 --- a/src/components/conversation/conversation.vue +++ b/src/components/conversation/conversation.vue @@ -21,34 +21,88 @@
