pyhound 0.1.0

A command-line client for the Hound source code search engine.

pyhound is a command-line client for the Hound source code search engine. It connects to a Hound server.

Requirements

pyhound requires Python 2.6, 2.7, 3.3 or 3.4.

Installation

pyhound needs a Hound server. See Hound documentation for further details. The steps below assume that you have a Hound server listening (for example on http://localhost:6080).

To install pyhound, use pip:

pip install pyhound

Features

pyhound aims to output search results in the manner of grep and hence implement some (but definitely not all) of its options.

The main feature of pyhound is its --help argument:

usage: pyhound [-h] [--version] [--endpoint URL] [--repos REPOSITORY_LIST]
               [--exclude-repos REPOSITORY_LIST] [--path FILE_PATH_PATTERN]
               [-A NUM] [-B NUM] [-C NUM] [--color [WHEN]] [-i] [-n]
               PATTERN

A command-line client for Hound.

positional arguments:
  PATTERN               The regular expression to search.

optional arguments:
  -h, --help            show this help message and exit
  --version             show program's version number and exit
  --endpoint URL        Host and port of the Hound server. You may also set a
                        HOUND_ENDPOINT environment variable. Default:
                        http://localhost:6080/
  --repos REPOSITORY_LIST
                        A comma-separated list of repositories to search in.
                        Default: all.
  --exclude-repos REPOSITORY_LIST
                        A comma-separated list of repositories to exclude.
  --path FILE_PATH_PATTERN
                        A pattern to match against the path of candidate
                        files.
  -A NUM, --after-context NUM
                        Print NUM lines of trailing context after matching
                        lines. Cannot be used with -C.
  -B NUM, --before-context NUM
                        Print NUM lines of leading context before matching
                        lines. Cannot be used with -C.
  -C NUM, --context NUM
                        Print NUM lines of output context. Cannot be used with
                        -A or -B.
  --color [WHEN], --colour [WHEN]
                        Surround the matched (non-empty) strings, file names,
                        line numbers and separators (for fields and groups of
                        context lines) with escape sequences to display them
                        in color on the terminal. WHEN may be "never",
                        "always" or "auto".
  -i, --ignore-case     Ignore case distinctions in both the PATTERN and the
                        input files.
  -n, --line-number     Prefix each line of output with the 1-based line
                        number within its input file.

Status

pyhound is considered beta. It’s only a few lines long and seems to work. However, it’s still very new and has not seen much diverse usage yet.

One of the current limitations is that pyhound currently tries to retrieve all search results in a single request to the Hound server. The server may return an error if there are too many results (currently: more than 5000) and pyhound will kindly display it. A future version of pyhound should handle this case and make multiple requests to the Hound server. Note that Hound web user interface has the same limitation and fails in a similar way (although it at least shows the first 20 results).

Alternatives

Apart from the web user interface, Hound comes with a command-line client. However it currently (Feb. 2015) has several limitations:

• it does not provide a grep-like output (although a TODO comment in the source suggests that it may appear someday);

• if there are more results that the Hound server can return in a single query, the command-line client displays nothing (as if there was no match at all).

The name

I must apologize. It’s the first time I write a Python package that starts with “py”. I thought I could resist a few years more. How naive of me…
