Not autosuggesting the values after brute force #14

Open albanx opened 2 years ago

albanx commented 2 years ago

Thanks again for this code it is really great.

I am having an issue integrating it with my local JS parser (using ANLTR4 4.9.3).

I have a SQL like grammar (sort of subset). When I run the autosuggest it starts doing a sort of brute force and at the end it does not find the property autosuggest value. For example when I start typing S for SELECT this is what I see in the console.log:

....
SUGGEST: tokenSoFar=DESCH remainingText= lexerState=131
debug.js?c20a:2 SUGGEST: tokenSoFar=DESCH remainingText= lexerState=63
debug.js?c20a:2 SUGGEST: tokenSoFar=DESCH remainingText= lexerState=137
debug.js?c20a:2 SUGGEST: tokenSoFar=DESCH remainingText= lexerState=63
debug.js?c20a:2 SUGGEST: tokenSoFar=DESC remainingText= lexerState=169
debug.js?c20a:2 SUGGEST: tokenSoFar=DESC remainingText= lexerState=28
debug.js?c20a:2 SUGGEST: tokenSoFar=DESC remainingText= lexerState=174
debug.js?c20a:2 SUGGEST: tokenSoFar=DESC remainingText= lexerState=30

debug.js?c20a:2       Not following visited 58->(1) 9
debug.js?c20a:2       Not following visited 109->(1) 29
debug.js?c20a:2 DROPPING non-parseable suggestion: GROM
debug.js?c20a:2 DROPPING non-parseable suggestion: GROMA
debug.js?c20a:2 DROPPING non-parseable suggestion: GROMAND
debug.js?c20a:2 DROPPING non-parseable suggestion: GROMANDELIT
debug.js?c20a:2 DROPPING non-parseable suggestion: GROMANDECT
debug.js?c20a:2 DROPPING non-parseable suggestion: GROMANDEC
debug.js?c20a:2 DROPPING non-parseable suggestion: GROMANDE
....

At the end autosuggests only:

['=', '!=', ')', ',']

Cannot understand if the issue is in the lexer definition or if I am doing something wrong. Would be great if I can have some help.
