gdir 0.3.2

gdir: Get Train/Bus Directions Using the Command Line
gdir is a command line tool which queries Google Directions. The tool displays results as human-readable text.

Installation
gdir is listed on the Python Package Index and may be installed using pip as follows:
$ python -m pip install gdir

Configuration
You will need a Google Directions API key. See Google Directions API documentation for instructions on how to obtain a key.
Set the shell environment variable GOOGLE_MAPS_API_KEY to your API key. This typically involves adding something like the following to your .profile file:
export GOOGLE_MAPS_API_KEY="XXXXXXXXXXXXXXXX-XXXXXXXXXXXXX-XXXXXXXX"
Note: If you don’t want to set up your own API key, there is a web-based version of gdir - try viewing https://gdir.telae.net in a terminal-based browser like links, lynx, or w3m! The web-based version implements most of the features described below.

Note: If you get a no directions found error, try appending the city to your origin/destination address. See also the -R flag below for setting region bias.

Detailed Help and List of Command Line Arguments
usage: gdir [-h] [-b] [-r] [-n] [-m] [-u] [-c | -k | -f]
[-d time_arg | -a time_arg] [-S] [-M] [-N] [-R region_code] [-C]
origin destination

Query the Google Directions API and write results to the standard output in
human-readable format. Uses public transport ('transit') mode by default.
Requires environment variable GOOGLE_MAPS_API_KEY defining a valid API key.
Language of directions is determined from locale configuration using
locale.getdefaultlocale(), which reads from LC_ALL, LC_CTYPE, LANG and
LANGUAGE in descending order of priority. Word wrapping is achieved using
shutil.get_terminal_size(), which reads from COLUMNS and which may
alternatively use system calls to determine the terminal width, using a fall-
back value of 80 if the terminal width could not be determined. Scripts may
use the -N flag (see below) to disable word wrapping but should not make
excessive assumptions about the structure of output: When using the -N flag,
valid assumptions are 1) routes are delimited by empty lines 2) each route may
be represented as a two-column table, where rows are separated by newlines and
where the first and second column in the table are separated by a single space
3) values in the first column may be left-padded with a variable amount of
whitespace 4) the format of values in the first column may vary for all rows,
including the first row 5) route output may be followed by two empty lines,
followed by travel warnings and/or copyright/transport agency information.
Status codes: 0 success; 1 generic error; 2 invalid argument; 3
origin/desination not found; >=4 google-maps-services-python exceptions.

-S, --substeps show sub-steps in output
-M, --multiple show multiple routes, if available
-N, --no-wrap disable word wrapping (affects command line mode only;
potentially useful for scripting)

set region bias using the specified top-level domain
two-character code (ccTLD)
-C, --copyright display copyright and transport agency information
(see Directions API terms and conditions)

Departure and arrival times are expressed in terms of local time at the origin
and destination, respectively. Times must be specified in the form
[[[[cc]yy]mm]dd]HH[:]MM[+N], where ccyy is the year, mm is the month (ranging
from 1 to 12), dd is the day (ranging from 1 to 31), HH is the hour (ranging
from 0 to 23) and MM is the minute (ranging from 0 to 59). When left
unspecified, ccyy, mm and dd values are assumed to be the current year, month
and day, respectively. For ambiguous times arising from daylight saving
transitions, it is assumed that the ambiguous time is expressed in the time
zone's standard time. The suffix +N may be used to offset the specified time
by N days. Thus, 12:00+1 means 'tomorrow at noon'.
