cuda_tern's Issues

References fail

yoba.js:

var yoba2 = require("./yoba2")

function yoba(a, b) {
    return a + b;
}

function foo(x) {
    return x;
}

yoba(foo(yoba(1, 2)), 3)
yoba2.b|ar()

yoba2.js:

function bar(a, b) {
    var c = [];
    return a * b;    
}

yoba(1, 2)

| — is cursor.

Here is for future, goto

LINE_GOTO_OFFSET=5

    def goto_file(self, filename, num_line, num_col):
        if not os.path.isfile(filename): return

        file_open(filename)
        ed.set_prop(PROP_LINE_TOP, str(max(0, num_line-LINE_GOTO_OFFSET)))
        ed.set_caret(num_col, num_line)

        msg_status('Go to file: '+filename)
        print('Goto "%s", Line %d'%(filename, num_line+1))

Timeout

can we pass TERN_TIMEOUT to tern too?
@pohmelie

Show err, if no Tern installed

when no Tern,

Traceback (most recent call last):
  File "<string>", line 2, in <module>
  File "/home/user/.cudatext/py/cuda_tern/__init__.py", line 14, in <module>
    stdout=subprocess.PIPE,

    restore_signals, start_new_session)
  File "/usr/lib/python3.4/subprocess.py", line 1457, in _execute_child
    raise child_exception_type(errno_num, err_msg)
FileNotFoundError: [Errno 2] No such file or directory: 'tern'

Wrong autocompl with Tern test

Get Tern js code
folder tern-master/test
util.js has 2 funcs addFile, addTest

Open reload.js, line 9, put caret after "util.add"
I see one result, must be 2

Rework get filename

now get of filename works for Tern tests, dont work for 1 file test.
How to get full filename from tern?

    # Tern gives "test/reload.js" while we edit "reload.js" in "test"
    dirname = os.path.dirname(os.path.dirname(ed.get_filename()))
    if dirname:
        filename = os.path.join(dirname, filename)

need check

(sx, sy), (ex, ey), *_ = token
Need check for tokens ended. ie get_token()==None

Docstring

Can u make method which gets docstr for cur function, and does print(s)? @pohmelie

host addr

127.0.0.1 is always ok, all OSes? "localhost" better.

Show er, if Tern cant start

i cannot run tern on 2nd PC. "tern" dont give output.
Cud shows

Traceback (most recent call last):
  File "/usr/lib/python3.4/http/client.py", line 786, in _get_hostport
    port = int(host[i+1:])
ValueError: invalid literal for int() with base 10: 'None'

Goto-def fix

In on_goto_def, return True, else Cud shows in statusbar "No goto def plugins installed"

Searching caller for proper argument hinting

function yoba(a, b) {
    return a + b;
}

function foo(x) {
    return x;
}

yoba(foo(yoba(1, 2))|, 3)

| is cursor position.
So, on ctrl-shift-space there should be hint about yoba arguments. To achieve this we should get token at caret position. And move "left" through tokens to find first yoba call.

For this cuda API should return index of token on get_token call too.
