export whole chat

[nanderer]

It would be nice to have a feature to export a whole chat session not only copy one prompt and answere.

Maybe a share conversation button to share the whole text and an export all button that creates a folder at on the device storage and a file for every conversation in it...

Thanks in advance

Similar with #127, but I'm thinking of implementing this. Thanks

I'm testing similar functionality for chat export using the following (just to get a working function, may polish later):

• Where chat export is available from with in chat, and the three dot menu, which includes Update chat title.
• Markdown formatted chat exports saved in Device path Android/data/<package_name>/files/chat_export_($date).md

ChatViewModel.kt

    fun exportChat() {
        val context = getApplication<Application>().applicationContext
        // Build the chat history in Markdown format
        val chatHistoryMarkdown = buildString {
            appendLine("# Chat Export: \"${chatRoom.value.title}\"")
            appendLine()
            appendLine("**Exported on:** ${formatCurrentDateTime()}")
            appendLine()
            appendLine("---")
            appendLine()
            appendLine("## Chat History")
            appendLine()
            messages.value.forEach { message ->
                val sender = if (message.platformType == null) "User" else "Assistant"
                appendLine("**$sender:**")
                appendLine(message.content)
                appendLine()
            }
        }
        // Save the Markdown file
        val fileName = "chat_export_${System.currentTimeMillis()}.md"
        val file = java.io.File(context.getExternalFilesDir(null), fileName)
        file.writeText(chatHistoryMarkdown)
        // Share the file
        val uri = androidx.core.content.FileProvider.getUriForFile(context, "com.hoshisato.eva", file)
        val shareIntent = Intent(Intent.ACTION_SEND).apply {
            type = "text/markdown"
            putExtra(Intent.EXTRA_STREAM, uri)
            addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
        }
        context.startActivity(Intent.createChooser(shareIntent, "Share Chat Export").apply {
            addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
        })
    }
    private fun formatCurrentDateTime(): String {
        val currentDate = java.util.Date()
        val format = java.text.SimpleDateFormat("yyyy-MM-dd hh:mm a", java.util.Locale.getDefault())
        return format.format(currentDate)
    }

topBar = { ChatTopBar(chatRoom.title, chatRoom.id > 0, onBackAction, scrollBehavior, chatViewModel::openChatTitleDialog, onExportChatItemClick = chatViewModel::exportChat) },

                onExportChatItemClick()
                onDismissRequest()
            }
        )
