| aquarius | I'd like to do the equivalent of bzr cat from a Python script -- that is, write a function which takes an lp URL for a file and returns the content of that file. Is the best approach to call the bzr cat command object and give it a StringIO to output into (which I can't work out how to do), or to do the things that the command object *does* myself? | 11:32 |
|---|---|---|
| aquarius | I *think* the way to do it is this: | 11:38 |
| aquarius | from bzrlib.plugin import load_plugins;load_plugins();from bzrlib.branch import Branch;remote_branch_url = 'lp:~sil/+junk/ucs-demo-app';b = Branch.open(remote_branch_url); tree=b.basis_tree(); file_id=tree.path2id('ubuntu_component_store.json'); print tree.get_file_text(file_id) | 11:39 |
| james_w | aquarius: that looks about right | 11:42 |
| aquarius | cool, I'm not doing anything insane, then :) | 11:42 |
| aquarius | am I better to check the file exists with tree.has_id first, or do I end up hitting the network twice then and so I should just catch exceptions on tree.path2id? | 11:43 |
| james_w | aquarius: catching an exception makes more sense I thinnk | 11:45 |
| james_w | aquarius: or I think it returns None in fact | 11:45 |
| aquarius | cool, then I'll just do it and check :) | 11:45 |
