Term::CallEditor - solicit data from an external editor
use Term::CallEditor qw/solicit/; my $fh = solicit('FOO: please replace this text'); die "$Term::CallEditor::errstr\n" unless $fh; print while <$fh>;
This module calls an external editor with an optional text message via the solicit() function, then returns any data from this editor as a file handle. By default, the EDITOR environment variable will be used, otherwise vi.
solicit()
vi
solicit() returns a temporary file handle pointing to what was written in the editor (or also the filename in list context).
solicit() as a second argument accepts a number of optional parameters as a hash reference.
solicit( "\x{8ACB}", { skip_interactive => 1, binmode_layer => ':utf8' } );
If true, enables binmode on the filehandle prior to writing the message to it.
binmode
If set, enables binmode on the filehandle prior to writing the message to it. Useful if one needs to write UTF-8 or some other encoded data as a message to the EDITOR.
Set a custom safe_level value for the File::Temp method of that name. The default safe_level is number 2. Be seeing you.
safe_level
If true, solicit skips making a test to see whether the terminal is interactive.
solicit
On error, solicit() returns undef. Consult $Term::CallEditor::errstr for details. Note that File::Temp may throw a fatal error if the safe_level checks fail, so paranoid coders should wrap the solicit call in an eval block.
undef
$Term::CallEditor::errstr
eval

Use a here doc:
my $fh = solicit(<< "END_BLARB"); FOO: This is an example designed to span multiple lines for FOO: the sake of an example that span multiple lines. END_BLARB
To use BBEdit as the external editor, create a shell script wrapper to call bbedit(1), then set this wrapper as the EDITOR environment variable. The -t option to bbedit(1) can be used to set a custom title, if desired.
-t
#!/bin/sh exec bbedit -w "$@"
Any editor that requires arguments will require a wrapper like this.
No known bugs.
Newer versions of this module may be available from CPAN.

This module relies heavily on the Unix terminal, permissions on the temporary directory (for the File::Temp module safe_level call), whether system() can actually run the EDITOR environment variable, and so forth.
