24 For particular projects you might well end up running the same commands
25 each time the REPL shell starts up - loading Perl modules, setting
26 configuration, and so on.
27
28 A mechanism called profiles exists to let you package and distribute
29 these start-up scripts, as Perl modules.
30
32 Quite simply, follow the "SYNOPSIS" section above to create a
33 boilerplate profile module. Within the "apply_profile" method, the
34 $repl variable can be used to run any commands as the user would,
35 within the context of their running "Devel::REPL" shell instance.
36
37 For example, to load a module, you might have something like this:
38
39 sub apply_profile {
40 my ($self, $repl) = @_;
41 $repl->eval('use Carp');
42 }
43
44 As you can see, the "eval" method is used to run any code. The user
45 won't see any output from that, and the code can "safely" die without
46 destroying the REPL shell. The return value of "eval" will be the
47 return value of the code you gave, or else if it died then a
48 "Devel::REPL::Error" object is returned.
49
50 If you want to load a "Devel::REPL" plugin, then use the following
51 method:
52
53 $repl->load_plugin('Timing');
54
55 The "load_plugin" and "eval" methods should cover most of what you
56 would want to do before the user has access to the shell. Remember that
57 plugin features are immediately available, so you can load for example
58 the "LexEnv" plugin, and then declare "my" variables which the user
59 will have access to.
60
61 Selecting a Profile
62 To run the shell with a particular profile, use the following command:
63
64 system$ re.pl --profile MyProject
65
66 Alternatively, you can set the environment variable
67 "DEVEL_REPL_PROFILE" to MyProject.
68
69 When the profile name is unqualified, as in the above example, the
70 profile is assumed to be in the "Devel::REPL::Profile::" namespace.
71 Otherwise if you pass something which contains the "::" character
72 sequence, it will be loaded as-is.
