57 | =head1 DESCRIPTION |
58 | |
59 | This part of the tutorial provides supporting information relevant to |
60 | the Catalyst tutorial. |
61 | |
62 | |
63 | =head1 APPENDIX 1: CUT AND PASTE FOR POD-BASED EXAMPLES |
64 | |
65 | You may notice that Pod indents example code with four spaces. This |
66 | section provides some quick advice to "un-indent" this text in common |
67 | editors. |
68 | |
69 | =head2 "Un-indenting" with Vi/Vim |
70 | |
71 | When cutting and pasting multi-line text from Pod-based documents, the |
72 | following vi/vim regexs can be helpful to "un-indent" the inserted text |
73 | (do NOT type the quotes, they are only included to show spaces in the |
74 | regex patterns). I<Note that all 3 of the regexs end in 4 spaces>: |
75 | |
76 | =over 4 |
77 | |
78 | =item * |
79 | |
80 | ":0,$s/^ " |
81 | |
82 | Removes four leading spaces from the entire file (from the first line, |
83 | C<0>, to the last line, C<$>). |
84 | |
85 | =item * |
86 | |
87 | "%s/^ " |
88 | |
89 | A shortcut for the previous item (C<%> specifies the entire file; so |
90 | this removes four leading spaces from every line). |
91 | |
92 | =item * |
93 | |
94 | ":.,$s/^ " |
95 | |
96 | Removes the first four spaces from the line the cursor is on at the time |
97 | the regex command is executed (".") to the last line of the file. |
98 | |
99 | =item * |
100 | |
101 | ":.,44s/^ " |
102 | |
103 | Removes four leading space from the current line through line 44 |
104 | (obviously adjust the C<44> to the appropriate value in your example). |
105 | |
106 | =back |
107 | |
108 | =head2 "Un-indenting" with Emacs |
109 | |
191dee29 |
110 | Although there author has not used Emacs for many years (apologies to |
111 | the Emacs fans out there), here is a quick hint to get you started. To |
d442cc9f |
112 | replace the leading spaces of every line in a file, use: |
113 | |
114 | M-x replace-regexp<RET> |
115 | Replace regexp: ^ <RET> |
116 | with: <RET> |
117 | |
118 | All of that will occur on the single line at the bottom of your screen. |
119 | Note that "<RET>" represents the return key/enter. Also, there are |
120 | four spaces after the "^" on the "Replace regexp:" line and no spaces |
121 | entered on the last line. |
122 | |
123 | You can limit the replacement operation by selecting text first (depending |
191dee29 |
124 | on your version of Emacs, you can either use the mouse or experiment with |
d442cc9f |
125 | commands such as C<C-SPC> to set the mark at the cursor location and |
126 | C<C-E<lt>> and C<C-E<gt>> to set the mark at the beginning and end of the |
127 | file respectively. |
128 | |
129 | |
130 | =head1 APPENDIX 2: USING MYSQL AND POSTGRESQL |
131 | |
132 | The main database used in this tutorial is the very simple yet powerful |
133 | SQLite. This section provides information that can be used to "convert" |
134 | the tutorial to use MySQL and PostgreSQL. However, note that part of |
135 | the beauty of the MVC architecture is that very little database-specific |
136 | code is spread throughout the system (at least when MVC is "done |
137 | right"). Consequently, converting from one database to another is |
138 | relatively painless with most Catalyst applications. In general, you |
139 | just need to adapt the schema definition C<.sql> file you use to |
140 | initialize your database and adjust a few configuration parameters. |
141 | |
142 | Also note that the purpose of the data definition statements for this |
143 | section are not designed to take maximum advantage of the various |
144 | features in each database for issues such as referential integrity and |
145 | field types/constraints. |
146 | |
147 | =head2 MySQL |
148 | |
149 | Use the following steps to adapt the tutorial to MySQL. Thanks to Jim |
150 | Howard for the help. |
