npm WARN enoent ENOENT: no such file or directory, open '/home/alberto/package.json'

@albfan Are you trying to install it in the package repo, or your home folder?

[albfan]

@Aerijo seems npm looks for that file outside the repo. I tried both approachs

[albfan]

I tried again and now it works, but

$ tree-sitter-cli
bash: tree-sitter-cli: no se encontró la orden

how should I run tree-sitter-cli?

[Aerijo]

The instructions go over this; inside the package directory, there’s a binary called tree-sitter in the node modules bin folder.

http://tree-sitter.github.io/tree-sitter/creating-parsers#installing-the-tools

[albfan]

That's instructions seems to cover when you want to generate new parser, I just want to test interactively existing ones

This is a fixed example that works, but I want to try different things quickly:

https://github.com/albfan/tree-sitter-c-parser-example

I tried ruby-tree-sitter but seems it is outdated

Can I use tree-sitter-cli without any new parser?

I cloned tree-sitter-c, cd into it and run:

$ ~/node_modules/.bin/tree-sitter test
/home/alberto/projects/tree-sitter/tree-sitter-c/index.js:7
    throw error
    ^

    at Function.Module._load (internal/modules/cjs/loader.js:529:3)

So, as first use case: what should I do to test interactively tree-sitter-c parser?

[Aerijo]

I was referring to this in particular, which describes how to set up and run the command provided by tree-sitter-cli

This will install the CLI and its dependencies into the node_modules folder in your directory. An executable program called tree-sitter will be created at the path ./node_modules/.bin/tree-sitter. You may want to follow the Node.js convention of adding ./node_modules/.bin to your PATH so that you can easily run this program when working in this directory.

And shortly after:

Then run the the following command:

tree-sitter generate
npm install

This will generate the C code required to parse this trivial language, as well as all of the files needed to compile and load this native parser as a Node.js module. You can test this parser by creating a source file with the contents hello; and parsing it:

tree-sitter parse ./the-file

I'm not sure what you mean by interactively though; you can use tree-sitter test to run all tests in the corpus folder, but live changes aren't possible.

To run the tests, you will need to build the parser. In general, compiled files are not checked into version control.

I am not quite sure whether or not this issue is related to mine but the title does match.
Currently installing tree-sitter-cli fails on my machine.
