.TH RL-LOOP 1 "Apr 10, 2024" 0.1.0 "ARIF User Manual"
|
||||
.
|
||||
.SH NAME
|
||||
rl-loop - Readline loop
|
||||
.
|
||||
.SH SYNOPSIS
|
||||
.B rl-loop
|
||||
.RI [ options ]
|
||||
.I pathname
|
||||
.RI [ args ]
|
||||
.
|
||||
.SH DESCRIPTION
|
||||
Interactively reads user input with GNU Readline.
|
||||
.PP
|
||||
For each line of user input, executes the program referred to by
|
||||
.IR pathname ,
|
||||
passing
|
||||
.I args
|
||||
as its command-line arguments.
|
||||
.
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
.B -e
|
||||
Executes
|
||||
.I pathname
|
||||
even if the input line is empty.
|
||||
.TP
|
||||
\fB\-i\fR \fIreplace-idx\fR
|
||||
When executing
|
||||
.IR pathname ,
|
||||
replaces the value of the nth (starting from 1) argument referred to by
|
||||
.I replace-idx
|
||||
with the line of text.
|
||||
.IP
|
||||
If this option is not provided, or has a value of 0, the line will be written
|
||||
to standard input instead.
|
||||
.TP
|
||||
\fB\-n\fR \fIname\fR
|
||||
Readline application name.
|
||||
Default value is "rl-loop".
|
||||
.IP
|
||||
Allows application-specific settings in a Readline init file.
|
||||
See "Conditional Init Constructs" subsection of GNU Readline's user manual.
|
||||
.TP
|
||||
\fB\-p\fR \fIprompt\fR
|
||||
The prompt text to be printed before reading user input.
|
||||
Default value is "% ".
|
||||
.
|
||||
.SH EXIT STATUS
|
||||
The program exits with status 0 if there are no errors, or 1 if otherwise.
|
||||
.
|
||||
.SH NOTES
|
||||
The functionalities provided by this program can be achived with a simple
|
||||
Bash script
|
||||
.RB ( "read -e"
|
||||
and friends).
|
||||
.PP
|
||||
However, Bash resets Readline state after each
|
||||
.BR read (1),
|
||||
necessitating the need to reinstall the completion functions if they are
|
||||
not handled by Bash, which could be tricky to workaround.
|
||||
.PP
|
||||
You may find this program useful when dealing with such cases (e.g. when using
|
||||
.BR arify (1)).
|
||||
.
|
||||
.SH EXAMPLES
|
||||
Copy each line to the Wayland clipboard:
|
||||
.PP
|
||||
.in +4n
|
||||
.EX
|
||||
$ rl-loop -i4 -- wl-copy -t text/plain -- %
|
||||
.EE
|
||||
.in

||||
