.TH ENTAB 1 local
2+
.SH NAME
3+
entab - tab processor
4+
.SH SYNOPSIS
5+
.nf
6+
entab [-cdq] [-s min_spaces] [-t tab_width] [file ... ]
7+
detab [-cq] [-s min_spaces] [-t tab_width] [file ... ]
8+
.fi
9+
.SH DESCRIPTION
10+
Entab is a program designed to selectively add or remove tabs
11+
from a file based on user-supplied criteria.
12+
In default mode, entab prints the specified files to standard output
13+
with the optimal mix of tabs and spaces.
14+
Tabs default to every 8 characters, and tabs are used only when they
15+
can replace more than one space, unlike 'col' which uses tabs wherever
16+
possible.
17+
.LP
18+
The options are:
19+
.in+0.5i
20+
.nf
21+
-c Clip trailing tabs and spaces from each line.
22+
-dDelete all tabs from output
23+
-qProtect single and double-quoted strings from tab replacement.
24+
(This option is useful when operating on source code.
25+
Line continuation with back-slashes is also understood.)
26+
-s Minimum spaces needed to replace with a tab (default = 2).
27+
-tNumber of spaces in a tab stop (default = 8).
28+
.fi
29+
.in-0.5i
30+
Detab is equivalent to entab -d.
31+
.SH NOTES
32+
Entab has improved tab handling for certain situations.
33+
It only replaces tabs if there is a user-defined number of spaces
34+
to be saved.
35+
Other tab replacement programs put tabs wherever
36+
possible, so if two words are separated by one space, and that
37+
space is on a tab stop, a tab is inserted.
38+
Then, when words are added to the left, the words are shifted over,
39+
leaving a large gap.
40+
The quote-protection option allows tab replacement without
41+
quoted strings being changed.
42+
Useful when strings in source code will not have the same tab stops
43+
when executed in the program.
44+
.LP
45+
To change a text file created on a system with one size of tab
46+
stop to display properly on a device with different tab setting,
47+
use detab (or entab -d) to remove tabs from the file with the
48+
tab size set to the original tab size, then use entab to re-tab
49+
the file with the new tab size.
