I get it work ^ ^ Haha!!
Thank you for your information!
First, insert below code in the beginning of "completions" function in
/base/REPLCompletions.jl
<https://github.com/JuliaLang/julia/blob/master/base/REPLCompletions.jl#L185>
:
try
if isdefined(Main, :CUSTOM_AUTOCOMPLETION_HOOK)
t=Main.CUSTOM_AUTOCOMPLETION_HOOK(string, pos)
if t[3]
return t
end
end
catch err
println("Error in CUSTOM_AUTOCOMPLETION_HOOK:")
println(err)
end
And recompile Julia. Now I have a hook for the custom-autocompletion.
Second, I define such function:
function CUSTOM_AUTOCOMPLETION_HOOK(txt,pos)
m=match(r"(\w+)\[\"([^\"]*)$",txt[1:pos])
if !isa(m,Nothing)
#For String key
if !isdefined(Main,parse(m.captures[1]))
return UTF8String[], 0:-1, false
end
var=eval(parse(m.captures[1]))
if !applicable(keys,var)
return UTF8String[], 0:-1, false
end
ky=keys(var)
if length(ky)>500
return UTF8String[], 0:-1, false
end
ky=[filter(x->isa(x,String),ky)...]
lst=convert(Vector{UTF8String},[filter(x->beginswith(x,m.captures[2]),ky)...])
if !(length(txt)>=pos+1 && txt[pos+1]=='\"')
if length(txt)>=pos+1 && txt[pos+1]==']'
lst=map(x->x*"\"",lst)
else
lst=map(x->x*"\"]",lst)
end
end
return lst, (pos-length(m.captures[2])+1):pos, true
else
#For symbol key
m=match(r"(\w+)\[\:(\w*)$",txt[1:pos])
if isa(m,Nothing) || !isdefined(Main,parse(m.captures[1]))
return UTF8String[], 0:-1, false
end
var=eval(parse(m.captures[1]))
if !applicable(keys,var)
return UTF8String[], 0:-1, false
end
ky=keys(var)
if length(ky)>500
return UTF8String[], 0:-1, false
end
ky=map(string,[filter(x->isa(x,Symbol),ky)...])
lst=convert(Vector{UTF8String},[filter(x->beginswith(x,m.captures[2]),ky)...])
if !(length(txt)>=pos+1 && txt[pos+1]==']')
lst=map(x->x*"]",lst)
end
return lst, (pos-length(m.captures[2])+1):pos, true
end
end
Now it is work on string and symbol key, really cool!
It can also auto-complete the method of python object ^ ^v
