RFC | Ways to improve dictionary suggestions.

Issue

One of the features of the language I’m proofreading is that it has vowels and consonants. The suggested list for editing distance 1 with different vowels should be at the beginning。

for fake exmaple: i have word adam, x is volwes and i have suggested list "adom", "adim", "adem", "adxm". the diff is o,i,e,x。 when I want to edit distance 1 and change the character to X words to be guaranteed to appear at the beginning of the suggested list, this cannot be done now.

If you control the order of the recommendation list with a regular expression, you should be able to do this。

Code I am testing

Here is a simple test case I did：

export function registerCompletionItemProvider() {
  vscode.languages.registerCompletionItemProvider("markdown", {
    provideCompletionItems() {
      // get the difference char from targer not in src
      const difference = (src, target) => {
        return Array.from(target).filter(
          (char) => !Array.from(src).includes(char)
        );
      };

      const orderReg = new RegExp("[x]");
      //const orderReg = new RegExp("[a-z]");

      const result = ["adom", "adim", "adem", "adxm"].map((item) => {
        const i = new vscode.CompletionItem(
          item,
          vscode.CompletionItemKind.Text
        );

        // for example my src word is "adam"
        if (orderReg.test(difference("adam", item).join(""))) {
          i.sortText = "a";
        }

        return i;
      });

      console.log("result", result);

      return result;
    },
    resolveCompletionItem(item) {
      return item;
    },
  });
}

The effect

The list of recommendations when I enter a when rule x is specified in the regular expression：

recommended list if no regular expression is specified:

Recommend

I think this is very useful in some special scenarios, so I recommend adding a regular rule configuration for suggesting list sorting

Would you try this:

    "dictionaryDefinitions": [
        {
            "name": "ug-khan",
            "path": "./khan.dict.trie.gz",
            "description": "Ug-khan dictionary for cspell.",
            "dictionaryInformation": {
                "alphabet": "\u0626-\u06d5",
                "locale": "ug",
                "suggestionEditCosts": [
                    {
                        "map": "\u0626\u0627\u0648\u0649\u06c6\u06c7\u06c8\u06d0\u06d5",
                        "insDel": 1,
                        "replace": 1,
                        "swap": 1
                    }
                ]
            }
        }
    ],

I get the following: (I don’t have RTL)

cspell suggestions -v دىگەن
