How to register a custom mapper with a complex file extension

[smartev3]

We made a custom JS mapper for CSDL XML files (OData CSDL XML is defined at http://docs.oasis-open.org/odata/odata-csdl-xml/v4.01/cs01/odata-csdl-xml-v4.01-cs01.html).

However in the VSCode JSON Settings we have to register it under the "codemap.xml" key, whereas we would rather register it under a key "codemap.csdl.xml" and have it apply only to XML files ending with the file extension ".csdl.xml".

Just wondering how to achieve it.

Here is the JS code.

"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
const fs = require("fs");

class mapper {

    static read_all_lines(file) {
        let text = fs.readFileSync(file, 'utf8');
        return text.split(/\r?\n/g);
    }

    static generate(file) {
        let members = [];
        try {
            let line_num = 0; 
            let image_index = 1;
            mapper
                .read_all_lines(file)
                .forEach(line => {
                    line_num++;
                    line = line.trimStart();
                    let firstIndex = line.indexOf('"');
                    let secondIndex = line.substr(firstIndex+1).indexOf('"');
                    if (line.startsWith("<Schema"))
                        members.push(`${line.substr(1, firstIndex+secondIndex+1)}|${line_num}|level1`);
                    else if (line.startsWith("<EntityType") || line.startsWith("<ComplexType") 
                        || line.startsWith("<EnumType") || line.startsWith("<TypeDefinition") 
                        || line.startsWith("<Term") || line.startsWith("<Action") 
                        || line.startsWith("<Function") || line.startsWith("<EntityContainer"))
                        members.push(`    ${line.substr(1, firstIndex+secondIndex+1)}|${line_num}|level2`);

            });
        }
        catch (error) {
        }
        return members;
    }
}
exports.mapper = mapper;

It will require changing the fila extension handling algorithm of the extension. But... I like the idea nd making the issue inti "Enhancement". Will implement it in the next release

Hi @oleg-shilo,

I'm also interested on this feature. Is it implemented in v1.23.0? Is not the case, there is planned to implement it? (or any way in which I can use it for custom extensions, for example filename.xml.m4, filename.xdm.m4 or filename.epc.m4).

Regards. Thanks for your extension, it is very useful.

Sorry guys, I am struggling to keep up with my other open-source projects. So this one is still in the queue...

[oleg-shilo]

But I will try to squeeze it into the next week.

Done: https://github.com/oleg-shilo/codemap.vscode/releases/tag/v1.24.0.0

ATTENTION:

Complex extensions should be dot-escaped in the config file with the / character due to the VSCode limitations of not handling dots in the config names correctly. IE the mapper configuration for the document.git.md file should be encoded in the setting.jeson as "codemap.git/md": "config:codemap.md",
