Alan Orth	a0ea829f5c	csv_metadata_quality/fix.py: Fixes should be green	2021-03-11 11:47:24 +02:00
Alan Orth	a7fc5a246c	Colorize output ... Messages will be colorized: - Red for errors - Yellow for warnings or information - Green for fixes	2021-02-21 13:01:25 +02:00
Alan Orth	0dc66c5c4e	Expand check/fix for multi-value separators ... I just came across some metadata that had unnecessary multi-value separators at the end of a field, causing a blank value to be used. For example: "Kenya||Tanzania||"	2021-01-03 15:30:03 +02:00
Alan Orth	7cfd4c0b59	csv_metadata_quality: Move scoped imports to global ... According to PEP8 we should avoid scoped imports unless you have a good reason. Here there are two cases where we do (issn and isbn), but I will move the others to the global scope.	2020-10-06 17:11:39 +03:00
Alan Orth	28b5996aa6	Output field name for more fixes and checks ... This helps identify which field has the error.	2020-01-16 12:35:11 +02:00
Alan Orth	365ecda324	Add utility function to check normalization ... Python's built-in unicodedata library includes the is_normalized() function starting with Python 3.8. This utility function allows us to do the same thing with earlier Python versions. See: https://docs.python.org/3/library/unicodedata.html	2020-01-15 12:17:52 +02:00
Alan Orth	49e3543878	Add Unicode normalization ... This will check all strings for un-normalized Unicode characters. Normalization is done using NFC. This includes tests and updated sample data (data/test.csv). See: https://withblue.ink/2019/03/11/why-you-need-to-normalize-unicode-strings.html	2020-01-15 11:37:54 +02:00
Alan Orth	e55380b4d5	csv_metadata_quality/fix.py: Harmonize language in fix output ... We should always say if we're removing or replacing something.	2019-10-01 17:09:49 +03:00
Alan Orth	c42f8b4812	csv_metadata_quality/fix.py: Replace non-breaking spaces ... We should be replacing non-breaking spaces (U+00A0) with normal sp- aces instead of removing them.	2019-10-01 16:55:04 +03:00
Alan Orth	280a99c8a8	Sort imports with isort ... See: https://sourcery.ai/blog/python-best-practices/	2019-08-29 01:15:04 +03:00
Alan Orth	d97dcd19db	Format with black	2019-08-29 01:10:39 +03:00
Alan Orth	81190d56bb	Add fix for missing space after commas ... This happens in names very often, for example in the contributor and citation fields. I will limit this to those fields for now and hide this fix behind the "unsafe fixes" option until I test it more.	2019-08-28 00:05:52 +03:00
Alan Orth	232ff99898	csv_metadata_quality/fix.py: Add more unneccessary Unicode fixes ... Add a check for soft hyphens (U+00AD). In one sample CSV I have a normal hyphen followed by a soft hyphen in an ISBN. This causes the ISBN validation to fail.	2019-08-11 00:07:21 +03:00
Alan Orth	40d5f7d81b	Add support for removing newlines ... This was tricky because of the nature of newlines. In actuality we are removing Unix line feeds here (U+000A) because Windows carriage returns are actually already removed by the string stripping in the whitespace fix. Creating the test case in Vim was difficult because I couldn't fig- ure out how to manually enter a line feed character. In the end I used a search and replace on a known pattern like "ALAN", replacing it with \r. Neither entering the Unicode code point (U+000A) direc- tly or typing an "Enter" character after ^V worked. Grrr.	2019-07-30 20:05:12 +03:00
Alan Orth	1e444cf040	Add fix for duplicate metadata values	2019-07-29 18:05:03 +03:00
Alan Orth	50ae4e17f2	csv_metadata_quality/fix.py: Fix indent	2019-07-29 17:14:48 +03:00
Alan Orth	8047a57cc5	Add support for fixing "unnecessary" Unicode ... These are things like non-breaking spaces, "replacement" characters, etc that add nothing to the metadata and often cause errors during parsing or displaying in a UI.	2019-07-29 16:38:10 +03:00
Alan Orth	42920e9c7c	Test Python regular expression matches directly ... Match objects always have a boolean value of True. See: https://docs.python.org/3.7/library/re.html	2019-07-29 16:16:30 +03:00
Alan Orth	40e77db713	Add "unsafe fixes" runtime option ... In this case it fixes occurences of invalid multi-value separators. DSpace uses "||" to separate multiple values in one field, but our editors sometimes give us files with mistakes like "|". We can fix these to be correct multi-value separators if we are sure that the metadata is not actually using "|" for some legitimate purpose.	2019-07-28 22:53:39 +03:00
Alan Orth	87b1997051	Fix whitespace errors found by flake8	2019-07-28 17:47:28 +03:00
Alan Orth	c47c064a13	Make output less debuggy	2019-07-27 09:21:13 +03:00
Alan Orth	2b41f9416b	csv_metadata_quality/fix.py: Remove extra newline	2019-07-27 01:29:22 +03:00
Alan Orth	30a4b0005f	csv_metadata_quality/fix.py: Remove test function	2019-07-26 22:56:40 +03:00
Alan Orth	232d28e13e	Refactor as package with subpackages ... This makes it cleaner for introducing checks, fixes, tests, docs, and tests in the future. Currently can be run like this: python -m csv_metadata_quality CSV input and output paths are still hard coded.
