I want to replace ${TM_FILENAME_BASE} with ${TM_DIRECTORY} if ${TM_FILENAME_BASE} is init
I tried this snippet. It works for all files not named init, otherwise the output is -- Name: $TM_DIRECTORY
{
"filename": {
"prefix": "filename",
"body": [
"${LINE_COMMENT} Name: ${TM_FILENAME_BASE/^init$/$TM_DIRECTORY/}"
]
},
}
You can't use a snippet variable in a transform. So your use of $TM_DIRECTORY will not be resolved to its actual value. See Snippet Grammar.
If the file is NOT named init, there is no match in
${TM_FILENAME_BASE/^init$/$TM_DIRECTORY/}
and so there is no transform and so ${TM_FILENAME_BASE} is inserted un-transformed.
The closest you are going to get with a pure snippet would be something like:
"filename": {
"prefix": "filename",
"body": [
// "${LINE_COMMENT} Name: ${TM_FILENAME_BASE/^init$/$TM_DIRECTORY/}"
"${LINE_COMMENT} Name: ${1:$TM_FILENAME_BASE}${2:$TM_DIRECTORY}"
]
}
Both options, the filenameBase and the directory would appear. First, the filenameBase would be selected - if you don't want it hit delete and tab past the directory. If you do want the filenameBase only, tab and delete the now-selected directory.
You can do what you want to do with an extension but it is more complicated. Let me know if you want to see it.
