在前文中,我们提到 Tree-sitter 的语法树字符串表示格式风格为 S-expression,这让我们可以更加直观的对语法树进行查询,因为这种 query 语言同样符合 S-expression 风格,我们最终的查询语句就是一组 S-expression。 这一节我们可以使用 Tree-sitter 官网的 Syntax Tree Playground (https://tree-sitter.github.io/tr...
ast-grep 提供的 playground 可以帮助你交互式的理解代码结构,编写出模式匹配的 pattern。ast-grep 也能提供基于 pattern 的搜索-替换功能。 辅助:helix 也可以查看某段代码的语法树结构。选中代码后,使用命令:tree-sitter-subtree 即可查看该段代码的语法树结构。 3. difftastic https://difftastic.wilfred.me.uk...
更进一步,ast-grep的元变量默认只匹配命名的节点。return $A 只匹配下面的第一条语句。 Playground链接。我们可以使用两个米元符号(非笔误)$$VAR在模式匹配的结果中包括匿名节点。return $$A将匹配上面的两个语句。 Playground链接。有时,仅仅使用kind并不足以找到我们想要的节点。一个节点可能有几个具有相同kind的...
I'm using tree-sitter 0.20.6 (3739b7794e381582c8f4a37b2ccec756c3504984) and when I generate && build-wasm && playground and open the browser and enter some text nothing happens and this is what I see in the console. RuntimeError: abort(A...
Does the playground handle encountered errors more gracefully, leading to the observed differences? Any clarification or guidance would be greatly appreciated. Thank you for your time. Steps to reproduce ### Setup grammar git clone --depth=1 https://github.com/tree-sitter/tree-sitter-c/ ...
The playground consists of a pane containing an editable TLA⁺ spec, and another pane containing the parse tree for that spec. The parse tree is updated in real time as you edit the TLA⁺ spec. You can click parse tree nodes to highlight the corresponding snippet of TLA⁺, and move...

Neat, eh? But don’t take my word for it, give it a go on thetree-sitter playground. Type in a query like so: 1 2 3 4 ; the web playground requires you to specify a"capture" ; you will notice the capture and the nodes it captured ...
