fixed a typo in this file (HISTORY.rst)

release r0.5.55

2021-02-15

  • fixed issue #324

Problem

  • The EnergyPlus objects can have legal names in the following format Special glass <thickness is 3mm>
  • Energyplus itself has no problems with such names
  • This name turns up in the HTML output file.
    • In the HTML file the part name`<thickness is 3mm>` looks like an HTML tag.
    • The browser tries to make sense of it and fix it so that something can be displayed
    • This results in a mangled name in the HTML file as viewed in the browser

Solution

  • Ideally this has to be fixed in Energyplus
  • eppy has a stop gap fix
  • eppy will ignore any tag within a cell of a table

release r0.5.54

2021-01-10

  • fixed issue #320
    • Problem: eppy.results.readhtml is very slow. Write similar function using generators
    • Solution: functions in eppy.fasthtml use lazy evaluation to get the tables quickly. This has been documented in user documentation in “Reading outputs from E+” and in “New functions”

release r0.5.53

2020-10-25

  • fixed issue #302
    • Problem: no documentation for multiprocessing runs

2020-06-13

  • fixed issue #289
    • Problem: E+ is unable to read numbers that are wider than 19 digits
    • Solution: format these numbers in scientific notation

2020-06-07

  • fixed issue #281
    • Problem: pytest failing in python 2
    • Solution: Set the correct version numbers in the requirements.txt file

2020-06-05

2019-09-14

  • fixed issue #245
    • Error handling errors in python 3

2019-08-17

  • fixed issue #254
    • when running a simulation:
      • Add expandobjects flag if any HVACTemplate objects are present in IDF

2019-08-03

  • fixed issue #251
    • Run black on the whole codebase.
    • Added black –check . to the Travis config for Python 3.7 on linux for master and non-master branches, to fail if formatting inconsistencies are found.

release r0.5.51

2019-07-14

  • updated version number in setup.py

release r0.5.50

2019-07-06

  • Fixed an installation bug
    • issue # 247

2019-06-11

  • Allows mixed cases for specifying objects:
    • issue # 242
  • the code now works in the following way:

    # you can use:
    objs = idf.idfobjects['ElectricEquipment']
    # instead of
    objs = idf.idfobjects['ElectricEquipment'.upper()]
    

2019-06-02

  • Fixes the TypeError
    • ‘TypeError: can only concatenate list (not “dict_keys”) to list’ is fixed
    • issue # 113, # 239

2019-05-27

  • fixed issue # 238
    • Problem: if the IDF object has more fileds than that in the IDD file, eppy will truncate the object and will give no warning.
    • Solution: eppy should throw an exception to warn the user that the IDF file is not readable without changing the IDD file.
    • The exception message will the text that has to be added to the IDD file, so that it works correctly.
