Question 1

How to remove duplicate lines from a log file with TF?

Accepted Answer

Use TF_RemoveDuplicateLines with parameters for the file path and options like Consecutive or CaseSensitive. For example, TF_RemoveDuplicateLines('log.txt', 1, 0, 1, false) removes consecutive duplicates without case sensitivity, as shown in the function examples.

Question 2

TF vs built-in AutoHotkey commands for text editing

Accepted Answer

TF provides a higher-level, function-rich API for complex tasks like column manipulation or file splitting, while built-in commands (e.g., FileRead, StringReplace) are faster for simple operations. TF is better for batch processing but adds overhead due to its line-by-line approach.

Question 3

Why does TF change my file's encoding?

Accepted Answer

TF uses AHK's FileEncoding command, but the README notes that encoding detection is imperfect without a BOM. To avoid issues, set FileEncoding at the start of your script, especially for UTF-8 files, as recommended in the 'File encoding, codepage' section.

Question 4

How to merge text files using TF?

Accepted Answer

Use TF_Merge with a FileList parameter containing paths, and optionally specify a separator and output filename. The README gives an example using Loop to gather *.txt files and merge them into 'merged.txt', but note it only works with files, not variables.

Question 5

Can TF handle regular expressions?

Accepted Answer

Yes, functions like TF_RegExReplace and TF_RegExReplaceInLines support regex for search patterns. The README cautions that special characters must be escaped and provides examples, such as wrapping lines in brackets using 'im)^(.*)$'.

Question 6

What does the ! prefix do in TF?

Accepted Answer

The ! prefix forces overwriting of the input file instead of creating a copy. For example, '!file.txt' will modify file.txt directly, while 'file.txt' creates file_copy.txt. The README explains this in 'Textfile and the ! Prefix' with multiple usage examples.

Question 7

Is TF suitable for processing CSV files?

Accepted Answer

TF is designed for general text manipulation and lacks dedicated CSV parsing functions. While you can use column operations like TF_ColGet, it treats tabs as single characters, so for structured CSV, a specialized library would be better, as hinted in the history section where CSV functions were removed.
