JSONParser.hs
Version 0.1.1
A simple example of parsing JSON with Parsec in haskell. Note that
since the primary point of this excersize is demonstration,
Text.Parsec.Token was avoided to expose more of the grammar. Also,
complicated optimizations and shorcuts were avoided (mostly).

Import Quattroshapes into PostgreSQL.

import quattroshapes into PostgreSQL

The import_quattroshapes_pgsql.sh shell-script will import all Quattroshapes shapefiles into a PostgreSQL database. The process has some gotchas and is generally painful to do manually. Before running the script, ensure that you are logged in as a user with permissions to access/write to PostgreSQL. Then:

bash import_quattroshapes_pgsql.sh

Note that the script will create a Postgres table quattroshapes, and download all Quattroshapes shapefiles into

Compile a full-featured Vim (w/ Python, Ruby, etc.).

compile full Vim

The default Vim installed on most Linux distros lacks a number of vital features, like xterm_clipboard (allows copy-and-pasting to the system clipboard) and python (on which certain plugins rely). The compile_full_vim.sh shell script removes the currently installed Vim and compiles a full-featured version; it's based entirely off Valloric's YouCompleteMe walkthrough, which it bundles into a simple script for convenience. Vim will be compiled with the following feature flags:

  • --with-features=huge
  • --enable-multibyte
