.SH "NAME"
incdec \- Readline bindings to increment and decrement numbers
.SH "SYNOPSIS"
.sp
Incdec bindings
.SH "DESCRIPTION"
.sp
A pair of Readline bindings and Bash functions to quickly increment and decrement a number on the current command line\&.
.SH "BINDINGS"
.PP
\fB__readline_incdec_decrement (C\-x x)\fR
.RS 4
Decrement the first number to the left of point by one\&. If no number is on the left of point, the first number to the right of point is decremented\&.
.RE
.PP
\fB__readline_incdec_increment (C\-x a)\fR
.RS 4
Increment the first number to the left of point by one\&. If no number is on the left of point, the first number to the right of point is incremented\&.
.RE
.SH "CUSTOM BINDINGS"
.sp
Custom bindings can be defined by mapping to the increment and decrement functions\&. For example, this defines bindings for \fIC\-x \-\fR and \fIC\-x +\fR:
.sp
.if n \{\
.RS 4
.\}
.nf
bind \-x \*(Aq"\eC\-x\-": __readline_incdec_decrement\*(Aq
bind \-x \*(Aq"\eC\-x+": __readline_incdec_increment\*(Aq
.fi
.if n \{\
.RE
.\}
