EmEditor
I have renewed unmitigated respect for EmEditor, a powerful editor that handles large text files with ease and grace. I am talking about a 500MB text file with 3.2 million lines and it still sorted it and deleted duplicates in it in a few seconds. In comparison, CotEditor on Mac, despite my delight in discovering its support for Unicode script/code block regex like \p{Han}, can't even handle one quarter of that (800K lines) without hanging indefinitely. It's such a pity that EmEditor, my favorite text editor bar none since I found it in 2000s, is Windows-only.
Verdict: 5 stars
Pros
- Large file support
- Onigmo regex engine supports
\p{Han} and the like.
