For Cuis version Cuis4.2-2243.image

# Section 1 -- Initial port without fixes

## File out from Pharo 4.0  / File in into Cuis

1. In Pharo 4.0 (May 2015) load NeoCSV package (one-click).

2. File out class packages

    - Neo-CSV-Core

    - Neo-CSV-Tests

3. Rename files to

    - Neo-CSV-Core-orig.st

    - Neo-CSV-Tests-orig.st

4. In Cuis open File List.

5. Install package SqueakCompatibility.pck.st

6. Do the following string replacements in the original files

   Replace ``codePoint``

   with ``unicodeCodePoint``

   Replace ``String crlf``

   with ``String crlfString``

   Replace ``String cr ``

   with ``String crString ``

   Note: there is a space after 'cr' and 'crString'

   Replace ``String lf``

   with ``String lfString``

5. Get code browser on 'Neo-CSV-Core-orig.st'

6. File in classes in the following order

    - NeoNumberParser

    - NeoCSVReader

    - NeoCSVWriter

7. Open 'World Menu'

8. Choose 'Open'

9. Choose 'Installed Packages'

10. Click on 'Create Package'

11. Type package name 'Neo-CSV-Core'

12. Enter a description. Include reference to source of the ported file.

    Port of Neo-CSV-Core-SvenVanCaekenberghe.22

13. Click on 'Save'

14. Open File list on 'Neo-CSV-Tests.st'

15. Get a code browser on 'Neo-CSV-Tests.st'

16. File in class #NeoCSVTestObject

17. File in NeoNumberParserTests

18. File in NeoCSVReaderTests

19. File in NeoCSVWriterTests

20. Do not file in class #NeoCSVBenchmark as it gives a waring Wthat ZnBufferedWriteStream and ZnBufferedReadStream are not defined.

21. Created a package 'Neo-CSV-Tests'

    Description: Port of Neo-CSV-Tests-SvenVanCaekenberghe.19

## Unit tests 

Run SUnit tests on code which was filed in:

Result is that 51 out of 52 tests passed.

# Section 2 -- Analysis

The following test fails

    testHexadecimalIntegers

	self assert: (NeoNumberParser parse: '7B' base: 16) equals: 123.

	self assert: (NeoNumberParser parse: '7b' base: 16) equals: 123.

	self assert: (NeoNumberParser parse: '-7B' base: 16) equals: -123.

	self assert: (NeoNumberParser parse: '-7b' base: 16) equals: -123.

	self assert: (NeoNumberParser parse: '0' base: 16) equals: 0.

The test does not fail if the code is changed to

     testHexadecimalIntegers

	self assert: (NeoNumberParser parse: '7B' base: 16) equals: 123.

	"self assert: (NeoNumberParser parse: '7b' base: 16) equals: 123."

	self assert: (NeoNumberParser parse: '-7B' base: 16) equals: -123.

	"self assert: (NeoNumberParser parse: '-7b' base: 16) equals: -123."

	self assert: (NeoNumberParser parse: '0' base: 16) equals: 0.

# Section 3 -- Code changes 

Fix code as described under section 2 -- analysis

## Result after fixing 

52 out of 52 tests are green.

## Conclusion -- Port status

- The port is OK.

- The package requires ``SqueakCompatibility.pck.st`` to be loaded and at least Cuis4.2-2243.image

- The following changes were applied to the code before file in

   Replace ``codePoint``

   with ``unicodeCodePoint``

   Replace ``String crlf``

   with ``String crlfString``

   Replace ``String cr ``

   with ``String crString ``

   Note: there is a space after 'cr' and 'crString'

   Replace ``String lf``

   with ``String lfString``

- Class #NeoCSVBenchmark has not been ported.

- Major port is done as of May 2015.
