32 Changes applied to dpkg-control configuration:

35 # show the script documentation
36 $ cme run remove-mia -doc
37 remove mia from Uploaders. require mia parameter
38
39 # list scripts
40 $ cme run -list
41 Available scripts:
42 - update-copyright
43 - add-me-to-uploaders
44
46 Run a script written with cme DSL (Design specific language) or in
47 plain Perl.
48
49 A script passed by name is searched in "~/.cme/scripts",
50 "/etc/cme/scripts" or "/usr/share/perl5/Config/Model/scripts". E.g.
51 with "cme run foo", "cme" loads either "~/.cme/scripts/foo",
52 "/etc/cme/scripts/foo" or "/usr/share/perl5/Config/Model/scripts/foo"
53
54 No search is done if the script is passed with a path (e.g. "cme run
55 ./foo")
56
57 "cme run" can also run plain Perl script. This is syntactic sugar to
58 avoid polluting global namespace, i.e. there's no need to store a
59 script using cme function in "/usr/local/bin/".
60
61 When run, this script:
62
63 • opens the configuration file of "app"
64
65 • applies the modifications specified with "load" instructions
66
67 • save the configuration files
68
69 • commits the result if "commit" is specified (either in script or on
70 command line).
71
72 See App::Cme::Command::run for details.
73
75 The script accepts instructions in the form:
76
77 key: value
78
79 The key line can be repeated when needed.
80
81 Multi line values can also be:
82
83 --- key
84 multi line value
85 ---
86
87 The script accepts the following instructions:
88
89 app Specify the target application. Must be one of the application
90 listed by "cme list" command. Mandatory. Only one "app" instruction
91 is allowed.
92
93 var Use Perl code to specify variables usable in this script. The Perl
94 code must store data in %var hash. For instance:
95
96 var: my @l = localtime; $var{year} = $l[5]+1900;
97
98 The hash %args contains the variables passed with the "-arg"
99 option. Reading a value from %args which is not set by user
100 triggers a missing option error. Use "exists" if you need to test
101 if a argument was set by user:
102
103 var: $var{foo} = exists $var{bar} ? $var{bar} : 'default' # good
104 var: $var{foo} = $var{bar} || 'default' # triggers a "missing arg" error
105
106 load
107 Specify the modifications to apply using a string as specified in
108 Config::Model::Loader. This string can contain variable (e.g. $foo)
109 which are replaced by command argument (e.g. "-arg foo=bar") or by
110 a variable set in var: line (e.g. $var{foo} as set above) or by an
111 environment variable (e.g. $ENV{foo})
112
113 commit
114 Specify that the change must be committed with the passed commit
115 message. When this option is used, "cme" raises an error if used on
116 a non-clean workspace. This option works only with git.
117
118 All instructions can use variables like $stuff whose value can be
119 specified with "-arg" options, with a Perl variable (from "var:"
120 section explained above) or with an environment variable:
121
122 For instance:
123
124 cme run -arg var1=foo -arg var2=bar
125
126 transforms the instruction:
127
128 load: ! a=$var1 b=$var2
129
130 in
131
132 load: ! a=foo b=bar
133
135 list
136 List available scripts and exits.
137
138 arg
139 Arguments for the cme scripts which are used to substitute variables.
140
141 doc
142 Show the script documentation. (Note that "--help" options show the
143 documentation of "cme run" command)
144
145 cat
146 Pop the hood and show the content of the script.
147
148 commit
149 Like the commit instruction in script. Specify that the change must be
150 committed with the passed commit message.
151
152 no-commit
153 Don't commit to git (even if the above option is set)
154
155 verbose
156 Show effect of the modify instructions.
157
159 See "Global Options" in cme.
