8063 | OPERATION is either nil or a string that names a supported operation. |
8064 | What operations can be used depends on the particular DOCUMENT and its | |
8065 | handler application, but typically it is one of the following common | |
8066 | operations: | |
8067 | ||
8068 | \"open\" - open DOCUMENT, which could be a file, a directory, or an | |
8069 | executable program. If it is an application, that | |
8070 | application is launched in the current buffer's default | |
8071 | directory. Otherwise, the application associated with | |
8072 | DOCUMENT is launched in the buffer's default directory. | |
8073 | \"print\" - print DOCUMENT, which must be a file | |
8074 | \"explore\" - start the Windows Explorer on DOCUMENT | |
8075 | \"edit\" - launch an editor and open DOCUMENT for editing; which | |
8076 | editor is launched depends on the association for the | |
8077 | specified DOCUMENT | |
8078 | \"find\" - initiate search starting from DOCUMENT which must specify | |
8079 | a directory | |
8080 | nil - invoke the default OPERATION, or \"open\" if default is | |
8081 | not defined or unavailable | |
8082 | ||
8083 | DOCUMENT is typically the name of a document file or a URL, but can | |
8084 | also be a program executable to run, or a directory to open in the | |
8085 | Windows Explorer. | |
8086 | ||
cca3fd48 JB |
8087 | If DOCUMENT is a program executable, the optional third arg PARAMETERS |
8088 | can be a string containing command line parameters that will be passed | |
8089 | to the program; otherwise, PARAMETERS should be nil or unspecified. | |
1dccd454 | 8090 | |
cca3fd48 | 8091 | Optional fourth argument SHOW-FLAG can be used to control how the |
1dccd454 | 8092 | application will be displayed when it is invoked. If SHOW-FLAG is nil |
cca3fd48 | 8093 | or unspecified, the application is displayed normally, otherwise it is |
