Of this dockerfile is that second and third lines are considered a single Handled as an instruction, cause it be treated as a line continuation. Similarly, the \ at the end of the third line would, assuming it was actually ![]() The second \ at the end of the second line would be interpreted as anĮscape for the newline, instead of a target of the escape from the first \. ` is consistentĬonsider the following example which would fail in a non-obvious way on Windows, where \ is the directory path separator. Setting the escape character to ` is especially useful on Note that regardless of whether the escape parserĭirective is included in a Dockerfile, escaping is not performed inĪ RUN command, except at the end of a line. The escape character is used both to escape characters in a line, and toĮscape a newline. If not specified, the default escape character is \. The escape directive sets the character used to escape characters in aĭockerfile. Line continuation characters are not supported in parserĭue to these rules, the following examples are all invalid: Convention is also to include a blank line following any However, convention is for them toīe lowercase. Parser directives are not case-sensitive. Therefore, all parser directives must be at the very Instead it treats anything formattedĪs a parser directive as a comment and does not attempt to validate if it mightīe a parser directive. Once a comment, empty line or builder instruction has been processed, Docker ![]() Special type of comment in the form # directive=value. Parser directives do not add layers to the build,Īnd will not be shown as a build step. It could be fun to keep with its industrial theme and have a "file" machine open for maintenance, with the cogs and wheels showing.Parser directives are optional, and affect the way in which subsequent lines It might be easier to find common ground with the icon for "The Big Mean Folder Machine". Both products can have separate identities. It would be an advantage if it fitted in well with the icon for its companion product "A Better Finder Rename", but this isn't crucial. The product icon is going to take up a good chunk of web page real-estate, so it needs to look good as a product logo as well as a product icon keep an eye out for what it's going to look like on the existing pages: It should look polished but not necessarily "serious" a bit wacky is okay. The icon has to be palatable to other graphics designers and photographers in particular. I don't have my heart set on a particular design, part of your work will be to come up with an icon that reflects the product's purpose and capabilities. * Original layered image file preferably in PSD format * Mac OS X icns file with all standard sizes from 512x512 The project is to design a new (hopefully better) icon for version 5 of the established A Better Finder Attributes product.įor more complete information on the product check out its homepage:
