surplus

Warning

this is surplus 2.0.0.
surplus is being rewritten to better incorporate with sandplus. sandplus is surplus's Android application accompaniment, written in Kotlin with Jetpack Compose.

you are on the future branch. if you see this warning, that means code is not finalised and ready to be used.
want the old, stable, working codebase? see the main branch.

surplus is a Python script to convert Google Maps Plus Codes to iOS Shortcuts-like shareable text.

$ surplus 9R3J+R9 Singapore
TODO CLI DEMO
>>> from surplus import surplus, Localcode
>>> Localcode(code="8RPQ+JW", locality="Singapore").full_length()
TODO API DEMO

installation

Note


python 3.11 or later is required due to a bug in earlier versions. (python/cpython#88089)

install surplus directly from the repository using pip:

pip install git+https://github.com/markjoshwel/surplus.git@future

command-line usage

usage: surplus [-h] [-d] [-v] [-c {pluscode,localcode,latlong,string}]
               [query ...]

Google Maps Plus Code to iOS Shortcuts-like shareable text

positional arguments:
  query                 full-length Plus Code (6PH58QMF+FX), shortened
                        Plus Code/'local code' (8QMF+FX Singapore),
                        latlong (1.3336875, 103.7749375), or string
                        query (e.g., 'Wisma Atria')

options:
  -h, --help            show this help message and exit
  -d, --debug           prints lat, long and reverser response dict to
                        stderr
  -v, --version         prints version information to stderr and exits
  -c {pluscode,localcode,latlong,shareabletext},
  --convert-to {pluscode,localcode,latlong,shareabletext}
                        converts query a specific output type, defaults
                        to 'shareabletext'

developer's guide

prerequisites:

alternatively, use devbox for a hermetic development environment powered by Nix.

devbox shell    # skip this if you aren't using devbox
poetry install
poetry shell

reporting incorrect output

Note

this section is independent from the rest of the contributing section.

different output from the iOS Shortcuts app is expected, however incorrect output is not.

the reporting process

open an issue in the repositories issue tracker, and do the following:

  1. ensure that your issue is not an error of incorrect data returned by your reverser function, which by default is OpenStreetMap Nominatim. (don't know what the above means? then you are using the default reverser.)

    also look at the what counts as "incorrect" section before moving on.

  2. include the erroneous query. (the Plus Code/local code/latlong coord/query string you passed into surplus)

  3. include output from the teminal with the --debug flag passed to the surplus CLI or with debug=True set in function calls.

    Note

    if you are using the surplus API and have passed custom stdout and stderr parameters to redirect output, include that instead.

  4. how it should look like instead, with reasoning if the error is not obvious. (e.g., missing details)

    for reference, see how the following issues were written:

what counts as "incorrect"

  • example (correct)

    • iOS Shortcuts Output

      Plaza Singapura
      68 Orchard Rd
      238839
      Singapore
      
    • surplus Output

      Plaza Singapura
      68 Orchard Road
      Museum
      238839
      Central, Singapore
      

    this should not be reported as incorrect, as the only difference between the two is that surplus displays more information.

    note: for singaporean readers, "Musuem" here is correct as it refers to the Museum planning area, in which Plaza Singapura is located in.

other examples that should not be reported are:

  • name of place is incorrect/different

    this may be due to incorrect data from the geolocator function, which is OpenStreetMap Nominatim by default. in the case of Nominatim, it means that there the data on OpenStreetMap is incorrect.

    (if so, then consider updating OpenStreetMap to help not just you, but other surplus and OpenStreetMap users!)

you should report when the output does not make logical sense, or something similar wherein the output of surplus is illogical to read or is not correct in the traditional sense of a correct address.

see the linked issues in the reporting process for examples of incorrect outputs.

the technical details of surplus's output

$ s+ --debug 8QJF+RP Singapore
TODO DEBUG OUTPUT

variables

  • variable args.query

    space-combined query given by user, comes from argparse.ArgumentParser.parse_args

  • variable squery

    query split by comma

    $ s+ 77Q4+7X Austin, Texas, USA
         --------------------------
         query
    
    squery -> ['77Q4+7X', 'Austin', 'Texas', 'USA']
    
  • variables pcode and locality

    (only shown if the query is a local code, not shown on full-length plus codes, latlong coordinates or string queries)

    represents the plus code and locality portions of a shortened plus code (referred to as a "short/local code" in the codebase) respectively.

  • variables lat and lon

    (only shown if the query is a plus code)

    the latitude longitude coordinates derived from the plus code.

  • variable location

    the response dictionary from the reverser passed to surplus.surplus()

  • variable seen_names

    a list of unique names/elements found in certain nominatim keys used in final output lines 0-3.

  • variables for seen name checks

    the variables come from a check to reduce repeated elements found in seen_names.

    • variable d

      current element in the iteration of the final output line 4 (general regional location) nominatim keys

    • variable _dvmt4

      list used in an all() check to see if the current nominatim key (variable d) can be wholly found in any of the seen names, in the general regional location, or in the road name.

      reasoning is, if the previous lines wholly state the general regional location of the query, there is no need to restate it.

      # psuedocode
      _dvtm4 = [
          d != "",
          d not in road,
          d not in [output line 4 (general regional location) nominatim keys],
          any(_dvcm4),
      ]
      
    • variable _dvcm4

      list used in an any() check to see if the current nominatim key (variable d) can be wholly found in any of the seen names.

      _dvcm4 = [True if (d not in sn) else False for sn in seen_names]
