[jira] [Commented] (FLINK-10515) Improve tokenisation of program
args passed as string
[ https://issues.apache.org/jira/browse/FLINK-10515?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17266130#comment-17266130 ]
Matthias commented on FLINK-10515:
----------------------------------
[~vthinkxie] Can we implement the deprecated tokenization logic easily in the web-frontend using JavaScript?
{code:java}
* tokenizeArguments("--foo bar") = ["--foo" "bar"]
* tokenizeArguments("--foo \"bar baz\"") = ["--foo" "bar baz"]
* tokenizeArguments("--foo 'bar baz'") = ["--foo" "bar baz"]
* tokenizeArguments(null) = [] {code}
It, more or less, uses double-quotes or single-quotes to group token together. If yes, we could proceed with [~azagrebin]'s proposal as is and keep the deprecated tokenization out of the Flink backend code.

> At the moment tokenisation of program args does not respect escape characters. It can be improved to support at least program args separated by spaces with unix style escaping.
