sfk detab=tabsize dir ext1 [ext2 ...] [-to outmask] replace tabs by spaces within file(s) or text stream. options -to outmask do not overwrite original files, but write to output files according to outmask, e.g. -to tmp\$path\$base.$ext or -to tmp\$file -yes if files are selected, really (re)write them. without -yes, detab is only simulated. -memlimit=n process files with up to n mbytes (default=300). -nowarn do not tell about skipped or unreadable files. see also sfk scantab list files containing TAB characters. sfk help opt how to change the memlimit permanently. sfk view a text file viewer that can show all TAB characters in blue by pressing CTRL+T. examples sfk detab=3 sources .cpp .hpp replace tabs by up to 3 blanks, within all .cpp and .hpp files of directory tree "sources". sfk select -dir src -file .java +detab=4 -to tmp\$file list all .java files of src, then detab with tabsize 4, writing all outputs to directory tree "tmp". sfk detab=4 src .java -relnames -to tmp\$file nearly the same, however stripping the "src" input directory name from output file paths (not possible with "+detab" form). sfk filter mytext.txt +detab=8 detab content of a single file to the console. to find how many files would need detabbing, type for example: sfk scantab testfiles .hpp .cpp .txt -> scans directory testfiles, and all subdirectories, for .hpp, .cpp and .txt files containing tab characters. example output: list of files containing tabs: testfiles\Formats\01-native-tab-crlf.txt testfiles\Formats\02-crlf.txt testfiles\Formats\03-native-tab-lf.txt testfiles\Formats\04-lf.txt testfiles\Formats\08-head-tail.txt testfiles\Formats\20-tab-data-line.txt 6 files of 32 contain tabs. to view TAB characters in your files interactively like this: - download the free text browser Depeche View Base. - click on "Open", select the folder containing your text files. - click on the "showtab" button in the right bottom corner. All TAB characters will be shown in blue, and all blanks in yellow. to search for TAB characters interactively: Within Depeche View, use the TAB keyword in your queries, e.g. - type "TAB " to find all TAB characters. (Type it all uppercase, and don't forget the blank after TAB) - type "TAB }" to find all curly brackets } preceeded by a tab: - type "foo TAB bar" to find the word combination "foo" and "bar" with exactly one TAB character inbetween. Note that the blanks around "TAB" are not used in the search.
