(1) Prep. (2) Add support for serializing json arrays and improve the robustness of QMP parsing (3) Add a special transaction( ... ) syntax that lets users build up transactional commands using the existing qmp shell syntax to define each action. (4) Add a verbose flag to display generated QMP commands. The parsing is not as robust as one would like, but this suffices without adding a proper parser. Design considerations: (1) Try not to disrupt the existing design of the qmp-shell. The existing API is not disturbed. (2) Pick a "magic token" such that it could not be confused for legitimate QMP/JSON syntax. Parentheses are used for this purpose. For convenience, this branch is available at: https://github.com/jnsnow/qemu.git branch qmp-shell++ This version is tagged qmp-shell++-v4. === v++ === - Use the AST to allow 'true', 'false' and 'null' within QMP expressions - Fix a bunch of stupid junk I broke in v2, apparently. === v3: === - Folding in hotfix from list (import ast) === v2: === - Squash patches 2 & 3: - Remove wholesale replacement of single quotes, in favor of try blocks that attempt to parse as pure JSON, then as Python. - Factored out the value parser block to accomplish the above. - Allow both true/True and false/False for values. - Fix typo in patch 3 cover letter. (was patch 4.)
