--【壹】--：
是一个话题的所有帖子 还是一个帖子单独的限制啊
--【贰】--：
是的 就是问佬的脚本有没有考虑这个问题特殊处理来着
--【叁】--：
每一条回复 我给你找找始皇发那个 等下哈
image910×272 35.1 KB
--【肆】--：
有点意思，佬可以上传一个到 greasyfork 或 GitHub 地址吗，方便更新
--【伍】--：

是的

--【柒】--：
不是字符，是一个主题只允许50个boost回应，50个人的小火箭
--【捌】--：
如果判定不够字数，回复会自动发boost吗？？
--【玖】--：
我还不知道这回事
等我去改一改 看一下情况
--【拾】--：
我看了下 本身 超过50个 就没有小火箭的按钮了 所以就会是普通回复的样子
--【拾壹】--：
linux.do 自动切换 boost/回复方式
≤16字自动走 Boost；17~19字保留普通回复并提示；20字及以上正常回复。支持同帖单用户仅1次 Boost、每帖 50 Boost 上限检测，并在不可 Boost 时自动切换普通回复提示。
--【拾贰】--：
佬请问下，bosst限制50个，超过50个时候这个脚本回复的boost会怎么处理
--【拾叁】--：
大召唤术，召唤哈雷表情包，佬友们快来助我
--【拾肆】--：
好东西，mm再也不担心boost吞我评论了
--【拾伍】--：
来了来了
--【拾陆】--：
既有存在50个的话 应该是不能再发送了的（不会显示小火箭）
所以如果直接打在接口上的话 那肯定是报错的
回复话题帖子的时候自动判断是否发送boost

是一个话题的所有帖子 还是一个帖子单独的限制啊
--【贰】--：
是的 就是问佬的脚本有没有考虑这个问题特殊处理来着
--【叁】--：

不是字符，是一个主题只允许50个boost回应，50个人的小火箭
--【捌】--：
如果判定不够字数，回复会自动发boost吗？？
--【玖】--：
我还不知道这回事
等我去改一改 看一下情况
--【拾】--：
我看了下 本身 超过50个 就没有小火箭的按钮了 所以就会是普通回复的样子
--【拾壹】--：
linux.do 自动切换 boost/回复方式
≤16字自动走 Boost；17~19字保留普通回复并提示；20字及以上正常回复。支持同帖单用户仅1次 Boost、每帖 50 Boost 上限检测，并在不可 Boost 时自动切换普通回复提示。
--【拾贰】--：
佬请问下，bosst限制50个，超过50个时候这个脚本回复的boost会怎么处理
--【拾叁】--：
大召唤术，召唤哈雷表情包，佬友们快来助我
--【拾肆】--：
好东西，mm再也不担心boost吞我评论了
--【拾伍】--：
来了来了
--【拾陆】--：
既有存在50个的话 应该是不能再发送了的（不会显示小火箭）
所以如果直接打在接口上的话 那肯定是报错的
