There is an AppleScript way (this is how Xcode does it): send an odoc
event to open a file with a "keyAEPosition" descriptor the data of
which should be the following struct
struct
{
int16_t unused1; // 0 (not used)
int16_t lineNum; // line to select (< 0 to specify range)
int32_t startRange; // start of selection range (if line < 0)
int32_t endRange; // end of selection range (if line < 0)
int32_t unused2; // 0 (not used)
int32_t theDate; // modification date/time
};
See, the -[MMAppController extractArgumentsFromOdocEvent:] for more
details on how MacVim parses this.
Alternatively, you may be able to use the mvim:// URL handler, see ":h mvim://".
Finally, if you have a specific MacVim window that you wish to open a
file in then you should use the --servername and --remote family of
arguments to the "mvim" script, e.g.
mvim --servername VIM --remote-silent filename
