A REPL for PhantomJS This covers [Issue 252](http://code.google.com/p/phantomjs/issues/detail?id=252) The commit is composed of 12 squashed commits: commit efdc6ba4f143c30a690fd97d92d80fa412e79999 Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Mon Feb 27 00:19:36 2012 +0000 Pretty-pringing and Completion Caching done! * This completes pretty-printing for the result of evaluated * expressions in the REPL. * Also, now we cache the "possible completions", to speed things up * a bit (nothing fancy though). * Minor tweaks to the internal doc and the way we "mock" * pretty-printing for QObjects/REPLCompletanle * All tests passing :) commit 1f9ef690e112a535b431fca409b77bb9c09d1c70 Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Sun Feb 26 22:35:00 2012 +0000 Moving most of REPL shim JavaScritp code in a separate file. Way easier to work on. commit 02d460a16fee14e7096ae7d899c03902c5b8a9c6 Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Sat Feb 25 20:25:18 2012 +0000 Initialisation of the Completions is now done in a pure virtual. This means that every REPLCompletable object will ACTUALLY register completion strings, ONLY if we are running a REPL and that object is ACTUALLY created. Otherwise, why bother? Adding completions for all exposed REPLCompletable objects Also, fixed an issue with _getCompletions() commit 412c3778fb04aa1c7379f8e760afce702b0428dd Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Tue Feb 21 00:49:17 2012 +0000 Few more tweaks to the REPL: - Now 'phantom' is the first QObject with proper completion - No repetition in QObject completions - LVAL of any user expression is now correctly prettified and printed Major things left to do: - Cache completions (using QCache?) - Add completions for the other QObject - When the LVAL of a user expression is a QObject, print what's expected, not the QObject "real" structure commit 46f04713c8165d898055e15478bb31403f8c93f1 Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Tue Feb 7 10:13:23 2012 -0800 Pretty-print expressions result Still not done though: there are issues with the NON-Native JS objects. commit 98b2fe67651dc750b62c6fa9cf1d80317fd9ae06 Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Fri Feb 3 00:22:52 2012 -0800 Introducing REPLCompletable. This class should be inherited by any JavaScript-exposed QObject, to ensure correct Auto-Completion. Correct auto-completion for QObjects. - Now even QObjects can correctly provide auto-completion, and avoid showing "not for users" methods - The strings used for the auto-completion are stored in a single Index: minimum memory footprint - Still, there is optimization that should be done (when "searching" for the right completion by prefix) - Completion for the objects not set up yet, but now it's just a trivial sequence of "addCompletion('bla')" in their constructors commit 9bd48618154b1530a37b41f4060440184e23253d Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Thu Feb 2 00:20:25 2012 -0800 Changing the way we import Linenoise. Will just import a specific commit, and update manually when needed. commit cfc9bae9fbdab13b01019b34b7cbd565e3153780 Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Sun Jan 29 23:22:26 2012 -0800 Made the REPL into a Singleton. With Auto-completion!. Reasons: 1) Needed a pointer to function (i.e. a static method) to be used with Linenoise to provide auto-completions 2) It makes more sense, as it's not like we are going to have 2 REPL running at the same time, are we? There are problems to address: - the enumeration in JS seems to return only the native interface of our objects - the function completions contain argument types of those functions - "private" methods are exposed commit c78bd32e17f8e0e4cc4a0066858de8cc81d33b97 Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Sun Jan 29 22:10:20 2012 -0800 Migrating from the original, now [unmantained Linenoise](https://github.com/antirez/linenoise) to the fairly active [tadmarshall fork](https://github.com/tadmarshall/linenoise). Also now the project is imported as a Git Submodule. Having migrated to the latest Linenoise (see prev. commit), now this _SHOULD_ work on Windows too. But, of course, this needs testing. :) commit 43713c5723d7c5ed446ba41ae8d6f8c9feba7f9b Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Tue Jan 24 23:17:06 2012 -0800 Now that the basics work, I'm adding support for REPL history.

A REPL for PhantomJS This covers [Issue 252](http://code.google.com/p/phantomjs/issues/detail?id=252) The commit is composed of 12 squashed commits: commit efdc6ba4f143c30a690fd97d92d80fa412e79999 Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Mon Feb 27 00:19:36 2012 +0000 Pretty-pringing and Completion Caching done! * This completes pretty-printing for the result of evaluated * expressions in the REPL. * Also, now we cache the "possible completions", to speed things up * a bit (nothing fancy though). * Minor tweaks to the internal doc and the way we "mock" * pretty-printing for QObjects/REPLCompletanle * All tests passing :) commit 1f9ef690e112a535b431fca409b77bb9c09d1c70 Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Sun Feb 26 22:35:00 2012 +0000 Moving most of REPL shim JavaScritp code in a separate file. Way easier to work on. commit 02d460a16fee14e7096ae7d899c03902c5b8a9c6 Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Sat Feb 25 20:25:18 2012 +0000 Initialisation of the Completions is now done in a pure virtual. This means that every REPLCompletable object will ACTUALLY register completion strings, ONLY if we are running a REPL and that object is ACTUALLY created. Otherwise, why bother? Adding completions for all exposed REPLCompletable objects Also, fixed an issue with _getCompletions() commit 412c3778fb04aa1c7379f8e760afce702b0428dd Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Tue Feb 21 00:49:17 2012 +0000 Few more tweaks to the REPL: - Now 'phantom' is the first QObject with proper completion - No repetition in QObject completions - LVAL of any user expression is now correctly prettified and printed Major things left to do: - Cache completions (using QCache?) - Add completions for the other QObject - When the LVAL of a user expression is a QObject, print what's expected, not the QObject "real" structure commit 46f04713c8165d898055e15478bb31403f8c93f1 Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Tue Feb 7 10:13:23 2012 -0800 Pretty-print expressions result Still not done though: there are issues with the NON-Native JS objects. commit 98b2fe67651dc750b62c6fa9cf1d80317fd9ae06 Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Fri Feb 3 00:22:52 2012 -0800 Introducing REPLCompletable. This class should be inherited by any JavaScript-exposed QObject, to ensure correct Auto-Completion. Correct auto-completion for QObjects. - Now even QObjects can correctly provide auto-completion, and avoid showing "not for users" methods - The strings used for the auto-completion are stored in a single Index: minimum memory footprint - Still, there is optimization that should be done (when "searching" for the right completion by prefix) - Completion for the objects not set up yet, but now it's just a trivial sequence of "addCompletion('bla')" in their constructors commit 9bd48618154b1530a37b41f4060440184e23253d Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Thu Feb 2 00:20:25 2012 -0800 Changing the way we import Linenoise. Will just import a specific commit, and update manually when needed. commit cfc9bae9fbdab13b01019b34b7cbd565e3153780 Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Sun Jan 29 23:22:26 2012 -0800 Made the REPL into a Singleton. With Auto-completion!. Reasons: 1) Needed a pointer to function (i.e. a static method) to be used with Linenoise to provide auto-completions 2) It makes more sense, as it's not like we are going to have 2 REPL running at the same time, are we? There are problems to address: - the enumeration in JS seems to return only the native interface of our objects - the function completions contain argument types of those functions - "private" methods are exposed commit c78bd32e17f8e0e4cc4a0066858de8cc81d33b97 Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Sun Jan 29 22:10:20 2012 -0800 Migrating from the original, now [unmantained Linenoise](https://github.com/antirez/linenoise) to the fairly active [tadmarshall fork](https://github.com/tadmarshall/linenoise). Also now the project is imported as a Git Submodule. Having migrated to the latest Linenoise (see prev. commit), now this _SHOULD_ work on Windows too. But, of course, this needs testing. :) commit 43713c5723d7c5ed446ba41ae8d6f8c9feba7f9b Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Tue Jan 24 23:17:06 2012 -0800 Now that the basics work, I'm adding support for REPL history. This is something almost everyone today is accustomed to. Also, now REPL history works! And I found some useful resources to solve pending TODOs. commit 31e5f88b044a5b4a823c67527ef8c245d2ac7863 Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Sun Jan 22 20:56:36 2012 -0800 Adding Linenoise Project (https://github.com/antirez/linenoise). For now is included as a drop-in set of files. Later on, if the Linenoise project has frequent updates, we might prefer to do it as a git-submodule. commit 4be9c15c65db4767e482fba0be13f8aab286d5f3 Author: Ivan De Marino <ivan.de.marino@gmail.com> Date: Thu Jan 5 15:31:13 2012 +0000 First simple REPL implementation. - Not complete - Still doesn't handle arrow keys (needed for history)
