locus's Issues

can't use with karma

I'd love to be able to use this to stop my angular tests under karma/phantom.js

Feature Request ↑

Hello, great tool. I use it every day. However, it would be nice to do an arrow up to get back to the code you just tested to modify so we don't need to type it again!

hitting up arrow does not show previously entered line

Hi, thanks for locus. What needs to be done to enable normal terminal behavior where hitting the up arrow would show historic commands?

Unable to define new variables

First off, this is amazing! I'm trying to debug an electron app, and the built in debugger sucks and crashes all the time. The pryjs package won't load at all. I installed this, and it did exactly what I expected right away.

Now, when I try to define a new variable in the console (like you can with pry), I just get undefined returns.

ʆ: var i = 0;
undefined
ʆ: i
ReferenceError: i is not defined

Usage ?

I'm not even sure of what your lib does (since doc is so short). I guessed it is a debug tool.

I try to follow the README and can't see any effect.

npm install locus

var locus = require('locus')

console.log('Hello world !');
var foo = 'bar';

eval(locus);

Would you mind enhancing the README a little ?

Consider replacement for sync-prompt?

This looks great (I love and dearly rely on binding.pry in ruby. However as far as I can tell, sync-prompt has build issues with node 0.11, 0.12 and iojs 1.8.1. So it's sort of a barrier to use. Thanks.

Documentation unclear

What does this module do? All I can tel from the readme is that this is meant to be used on a REPL, but opening a REPL with "with access to all variables" means literally nothing to me. Please clarify. The example with a screenshot didn't help..

Autocompletion Support

Hey,

I think it's possible and useful to add autocompletion to locus, I really like the idea, a true debugging assistant.

I'm a little busy with a few open-source projects and some other work, but I will definitely take a look, what do you think @alidavut?

TypeError: Generator is already running

I get this whenever I try to type anything after the REPL is shown. Not in all places of the script, but in many. I don't know why, perhaps because I'm calling it inside callback functions or some other async magic?

Here's an example:

 /home/fiatjaf/comp/wft/trelew/index.js - Line: 194 
————————————————————————————————————————————————————
186 : 
187 :     // list comments
188 :     var comments = vorpal.find('comments')
189 :     if (comments) comments.remove()
190 :     vorpal
191 :       .command('comments', "list this card's comments.")
192 :       .alias('ls comments')
193 :       .action(function (_, cb) {
ʆ: readline.js:924
            throw err;
            ^

npm-debug.log

Is it possible to use locus in node console?

Got following error when calling a function containing "eval(locus)":
Error: ENOENT: no such file or directory, open 'repl'

It would be great if it is possible to debug inside node console.

Does not work on Windows

I am using WSL, but it seems like this issue is more general for Windows. Installation works, and the first run of locus appears to work fine as well. However, after exiting, all subsequent calls to locus produce something like this

File : /home/kloughead/projects/API_demo/app.js @ line: 12

     6: const request = require('request');
     7: require('locus');
     8: 
     9: 
    10: request('https://jsonplaceholder.typicode.com/users/1', function(error, response, body) {
    11:     if (!error && response.statusCode == 200) {
 => 12:         eval(locus)
    13:         var parsedData = JSON.parse(body);
    14:         console.log(parsedData);
    15:     }

internal/fs/streams.js:59
    throw new ERR_OUT_OF_RANGE(name, '>= 0 and <= 2 ** 53 - 1', pos);

I am taking a course on Udemy and there are others having similar issues. We were told by the teaching assistant to try installing version 2.0.0, but that fails also. Installation works, all calls stop just for the interactive portion. That is, you see something like this:

     6: const request = require('request');
     7: require('locus');
     8: 
     9: 
    10: request('https://jsonplaceholder.typicode.com/users/1', function(error, response, body) {
    11:     if (!error && response.statusCode == 200) {
 => 12:         eval(locus)
    13:         var parsedData = JSON.parse(body);
    14:         console.log(parsedData);
    15:     }

Unable to install on Windows

Looks like this requires Python to run which Windows doesn't have by default. Might need to add that to the README as a requirement.
