152 | =head1 SYNOPSIS |
132 | |
153 | |
133 | cv [file...] |
154 | cv [file...] |
134 | |
155 | |
|
|
156 | =head1 FEATURES |
|
|
157 | |
|
|
158 | CV is supposed to work similar to the venerable XV image viewer, just |
|
|
159 | faster. Why faster? |
|
|
160 | |
|
|
161 | =over 4 |
|
|
162 | |
|
|
163 | =item * optimized directory scanning algorithm |
|
|
164 | |
|
|
165 | The directory scanning in CV plays some tricks that - on most modern |
|
|
166 | filesystems - makes it possible to detect filetypes faster than stat()'ing |
|
|
167 | every file. This makes CV suitable for directories with lots of files |
|
|
168 | (10000+). |
|
|
169 | |
|
|
170 | This algorithm is quite unprecise - it doesn't make a difference between |
|
|
171 | files, device nodes, symlinks and the like, and filetype detection is done |
|
|
172 | using the file extension only. |
|
|
173 | |
|
|
174 | =item * use of asynchronous I/O |
|
|
175 | |
|
|
176 | CV tries to use asynchronous I/O whereever it makes sense, for example |
|
|
177 | while scanning directories, waiting for stat data or unlinking files. This |
|
|
178 | usually decreases scanning times for large directories a bit (especially |
|
|
179 | on RAID devices and over NFS). |
|
|
180 | |
|
|
181 | =item * fast image loading |
|
|
182 | |
|
|
183 | The time span between the user issuing a command and displaying the new |
|
|
184 | image should be as small as possible. CV uses optimized (especially |
|
|
185 | for JPEG) loading functions and sacrifices some quality (e.g no gamma |
|
|
186 | correction) to achieve this speed. |
|
|
187 | |
|
|
188 | =item * fast thumbnail creation |
|
|
189 | |
|
|
190 | Thumbnail creation is crucial for me, so it's better be fast. Thumbnail |
|
|
191 | creation for JPEGs has been specially optimized. |
|
|
192 | |
|
|
193 | =item * minimum optical clutter |
|
|
194 | |
|
|
195 | CV has no menus or other user interface elements that take up a lot of |
|
|
196 | screen space. The schnauzer windows can also be somewhat crowded. |
|
|
197 | |
|
|
198 | The point of an image viewer is viewing images, not a nice GUI. This is |
|
|
199 | similar to XV's behaviour. |
|
|
200 | |
|
|
201 | =item * efficient (and hard to learn) user interface |
|
|
202 | |
|
|
203 | CV uses key combinations. A lot. If you are an experienced XV user, you |
|
|
204 | will find most of these keys familiar. If not, CV might be hard to use at |
|
|
205 | first, but will be an efficient tool later. |
|
|
206 | |
|
|
207 | =item * i18n'ed filename handling throughout |
|
|
208 | |
|
|
209 | As long as glib can recognize your filename encoding (either UTF-8 or |
|
|
210 | locale-specific, depending on your settings) and you have the relevant |
|
|
211 | fonts, CV will display your filenames correctly. |
|
|
212 | |
|
|
213 | =item * extensible through plug-ins |
|
|
214 | |
|
|
215 | I have weird plug-ins that access remote databases to find a |
|
|
216 | directory. This is not likely to be of any use to other people. Likewise, |
|
|
217 | others might have weird requirements I cannot dream of. |
|
|
218 | |
|
|
219 | =item * filename clustering |
|
|
220 | |
|
|
221 | Among the standard plug-ins is a filename clustering plug-in, that (in |
|
|
222 | case of tens of thousands images in one directory) might be able to |
|
|
223 | cluster similar names together. |

|
|
306 | When starting, CV runs the F<.cvrc> file in your F<$HOME> directory as if |
|
|
307 | it were a perl script. in that, you will mostly load plug-ins. |
|
|
308 | |
|
|
309 | Example: |
|
|
310 | |
|
|
311 | system "fping -q -t 10 ether" |
|
|
312 | or require "/fs/cv/cvplugin.pl"; |
|
|
313 | |
|
|
314 | This will load a plug-in, but only if the machine I<ether> is reachable |
|
|
315 | (supposedly the plug-in is networked in some way :). |
