Aligning
The align-region command on Ctrl-c Ctrl-a aligns
elements on lines within the current region. It changes the spacing
just before each element, so it starts at the same column on every
line where it occurs.
It uses alignment rules specialized for the current mode. By default,
it aligns the first "=" character on each line, and any comments
on the lines.
For C mode, Epsilon additionally aligns the names of variables being
defined (in simple definitions), the definitions of macros in
#define lines, and the backslash character at the end of
preprocessor commands. It can change
int hour = 3; // The hour.
short int minute = 22; // The minute.
int second = 14; // The second.
#define GET_HOUR() hour // Get the hour.
#define GET_MINUTE() minute // Get the minute.
#define GET_SECOND() second // Get the second.
into
int hour = 3; // The hour.
short int minute = 22; // The minute.
int second = 14; // The second.
#define GET_HOUR() hour // Get the hour.
#define GET_MINUTE() minute // Get the minute.
#define GET_SECOND() second // Get the second.
You can disable individual alignment rules by setting the
align-region-rules variable, or increase the minimum spacing
used by all automatic rules by setting the
align-region-extra-space variable.
The command can also perform alignments specified manually. Run it
with a numeric prefix argument, and it will prompt for a regular
expression pattern that defines the alignment rule. It must consist
of two parenthesized patterns, such that in a regular expression
replacement, #1 and #2 would substitute their text.
Alignment will alter the spacing between these two elements. Manual
alignment will also prompt for the amount of additional spacing to be
added between the two elements.
To use the built-in mode-based rules, but add extra space, run
align-region with a numeric prefix, but enter nothing for the
search pattern. The command will prompt for the amount of additional
space and apply it using the mode's default alignment rules, as if you
had temporarily modified the align-region-extra-space variable.
The align-by-tab command modifies tab-delimited text in the
region (text that uses a single tab character to mark each new column,
such as text copied from a spreadsheet), reformatting it using spaces
and tabs so the text appears in columns. It makes each column just
wide enough for its contents.
