apinstein / iphp Goto Github PK

this :
h:> php -f iphp.php
h:>

on windows 7;

how could i use the iphp.php?

See patch: http://github.com/jetviper21/iphp/commit/2ac55340d8c6654b703748b26ab585fc333fb66a#comment_38069

Read comments for architecture ideas.

Maybe use the built-in PHP parser to see if we're in the middle of a statement and allow multi-line input until a ; or some other signal is entered on a single line?

Or maybe have a multi-line internal command? like

foreach ($a as $b) {
print $b;
}
;

I have an idea to use token_get_all() to parse the input and do lexical analysis on the code entered so far to improve the autocomplete list.

So if you have a class Foo with methods bar() and baz() you would see:

$foo = new Foo;
$foo->b
bar baz

This could be done with real-time reflection.

@apinstein will you please give a status update

Where is the project at?
Where is the project going?
How much time can you commit to this project?
Known PHP version support?
Any other dependencies?

I installed and immediately readline is not working which is should so I haven't looked at it any closer thought I might get your response first.

I've been using facebook's phpsh and recently made some modifications realizing that there really isn't much preventing us from doing it all in php. Started playing with ipython and why don't we have iphp was the thought that came to mind. Hence a google search landed me here.

Interested? Plausible? Know of any other similar projects perhaps?

Looking forward to hearing your thoughts,.

the readme file should list the requirements for running iphp.

So far, I can see PHP 5 >= 5.1 is needed because of use of the readline_callback_handler_install function. and, php-cli is also needed.

also, PHP must be compiled with option --with-readline

This helps us solve gh-4, gh-5, gh-8, gh-9

If we run all input thru the tokenizer, we should be able to figure out where we're at in the current scope to improve auto-complete, allow multiline functions, tell if things have return values, etc.

A simple PEAR package for this project would make it really easy for php-ers to have a one-line install that will put the iphp bin in their path.

Eventually the (pearfarm project)[http://github.com/fgrehm/pearfarm] will help with that, but it's not quite ready yet...

Anyone wanna take a crack at the PEAR package?

I have readline installed, not sure why I am getting an undefined function call. System information and command output is below.

$ ./iphp
Welcome to iphp, the interactive php shell!

Features include:
- autocomplete (tab key)
- readline support w/history
- automatically wired into your project's autoload

Enter a php statement at the prompt, and it will be evaluated. The variable $_ will contain the result.

Example:

> new ArrayObject(array(1,2))
ArrayObject Object
(
    [0] => 1
    [1] => 2
)

> $_[0] + 1
2

Presently a command like:

foreach(array(1,2) as $i) { echo $i; }

fails since the generated code is like:

$_ = foreach() ...

Maybe use the built-in php parser to figure out if we're in such a case?

This was bugging me for awhile and i hacked away for about 2.5 hours trying to figure out a work about but

While i had a work around working the storing of $_ and $__out are not possible when you create a a special case even "foreach" will explode using serialization

foreach(range(0,10) as $i) { echo $i; }

Solution is avoid serialization and store the code input unserialized in a file and keep appending to it and re-executing, As for returning output some string parsing may be in order to find variables and var_dump-ing them may be in order or just rely or just print tokenize the last returnable line;
