ruby - Proc causing a random TypeError -


i'm refactoring code , proc causing error randomly , don't know why or how debug it... ideas?

new code proc

  defense_moves, offense_moves = [], []   determine_move = ->move,side,i { side << move.count(move[i]) }   defense.size.times { |i| determine_move.(defense, defense_moves, i) }   offense.size.times { |i| determine_move.(offense, offense_moves, i) }   dm = defense[defense_moves.index(defense_moves.max)].nil? ? [0] : defense[defense_moves.index(defense_moves.max)]   om = offense[offense_moves.index(offense_moves.max)].nil? ? [0] : offense[offense_moves.index(offense_moves.max)]

original code:

  d = 0   defense_moves = []   loop      defense_moves << defense.count(defense[d])     break if defense.count(defense[d]).zero?     d += 1   end    o = 0   offense_moves = []   loop      offense_moves << offense.count(offense[o])     break if offense.count(offense[o]).zero?     o += 1   end    dm = defense[defense_moves.index(defense_moves.max)].nil? ? [0] : defense[defense_moves.index(defense_moves.max)]   om = offense[offense_moves.index(offense_moves.max)].nil? ? [0] : offense[offense_moves.index(offense_moves.max)]

typeerror

ttt2.rb:95:in `[]': no implicit conversion nil integer (typeerror)     ttt2.rb:95:in `computer_make_move'     ttt2.rb:133:in `draw_board'     ttt2.rb:24:in `place'     ttt2.rb:209:in `block in start_new_game'     ttt2.rb:188:in `loop'     ttt2.rb:188:in `start_new_game'     ttt2.rb:199:in `block in start_new_game'     ttt2.rb:188:in `loop'     ttt2.rb:188:in `start_new_game'     ttt2.rb:199:in `block in start_new_game'     ttt2.rb:188:in `loop'     ttt2.rb:188:in `start_new_game'     ttt2.rb:199:in `block in start_new_game'     ttt2.rb:188:in `loop'     ttt2.rb:188:in `start_new_game'     ttt2.rb:199:in `block in start_new_game'     ttt2.rb:188:in `loop'     ttt2.rb:188:in `start_new_game'     ttt2.rb:234:in `<main>'

so, before code that:

defense_moves, offense_moves = [], [] determine_move = -> move, side, { side << move.count(move[i]) } (defense.size + 1).times { |i| determine_move.(defense, defense_moves, i) } (offense.size + 1).times { |i| determine_move.(offense, offense_moves, i) } dm = defense[defense_moves.index(defense_moves.max)].nil? ? [0] : defense[defense_moves.index(defense_moves.max)] om = offense[offense_moves.index(offense_moves.max)].nil? ? [0] : offense[offense_moves.index(offense_moves.max)]

(defense/offence.size + 1), cause break after adding array.

i'm not sure proper or not, guess works same loops.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod...
