我开发了一种名为PTL. 我想在 Atom 中为它突出显示语法，所以我按照相应的指南为它创建了一个工作的 tree-sitter 解析器。通过大量的调试，我设法将解析器安装为 Atom 可以读取的包。
我使用以下文件测试了解析器
input.ptl：
==================
ptlExample
==================
#define myvar 4
#define myvartwo 2
GlobalSettings
{
Display
{
debugLevel = $(myvar)
debugLevelzap = 3
}
Memory
{
allowStackAllocation = false
}
}
Domain
{
blockDim = [1, 2, 2]
coolio = @sqrt($(myvartwo))
}
//parallel

测试是成功的，所以我相信 tree-sitter 正在捕获完整的语法树。但是，在安装之后，当我在 atom 中打开我的确切文件时（只有内容，没有像标题和预期语法树这样的树保姆额外内容），没有任何东西是正确的，并且整个文件都有ptl范围。我有以下范围：
scopes:
'comment > string_identifier': 'comment.line.double-slash.ptl'
所以至少，应该拿起最后的评论。它不是。我已经看到这个线程描述了完全相同的问题，但修复涉及更新 Atom 的语法获取功能以识别树保姆语法。我正在运行更新版本的 Atom，所以这不是原因。我该如何调试呢？
编辑：我在控制台中发现了一个错误：

基于此，看起来我需要使用不同版本的 tree-sitter 重建我的包，尽管我不知道 tree-sitter Atom 使用哪个版本。这是否意味着我需要更新 Atom 的 tree-sitter 版本（似乎更可取），还是需要降级我在包中使用的 tree-sitter 版本？
