Marc Durdin 2c01b19f69 chore: cleanup
1. Renamed form UfrmNGrokOptions to UfrmServerOptions
2. Renamed kmdev-server to just plain server
3. Tidied up npm versioning to use VERSION_WITH_TAG

This last point should help avoid confusion as now only CI release
builds will ever generate a package.json with a.b.c, a.b.c-alpha or
a.b.c-beta. Local and test builds will always have the corresponding
-test or -local environment appended. This also helps avoid issues if
we accidentally publish an incorrect version.

# npm packages
This is a guide for how the various Keyman `npm` packages are developed
and published.
`npm` packages are published on the CI (continuous integration) server.
Currently, we're using TeamCity for this.
Packages are **never** published from a developer's machine.
## List of current npm packages
* `@keymanapp/models-types` -- located at `common/models-types`
* `@keymanapp/lexical-model-compiler` -- located at `developer/js`
## For CI developers
### In general
Before publishing, a package must be **built** and **tested** on the CI
server.
This is typically done with:
```bash
./build.sh -test
```
Once the build succeeds and the tests pass, the version is set in
`package.json`:
```bash
./build.sh -version 12.0.${BUILD_NUMBER} -tier ${tier}
```
Now you can publish! Use the following script for this (again, **only on the CI server**!)
```bash
./build.sh -publish-to-npm -tier ${tier}
```
It is then uploaded to the npm package directory. **Ensure that the
compiled sources are included in the tarball**. For example,
```bash
$ npm publish
npm notice 📦 @keymanapp/lexical-model-compiler@0.0.0
npm notice === Tarball Contents ===
npm notice 12.4kB dist/lexical-model-compiler/build-trie.js
npm notice 1.2kB dist/kmlmc.js

npm notice 5.0kB dist/package-compiler/kmp-compiler.js
npm notice 55B dist/package-compiler/kmp-json-file.js
npm notice 552B dist/package-compiler/kps-file.js
npm notice 4.6kB dist/lexical-model-compiler/lexical-model-compiler.js
npm notice 315B dist/lexical-model-compiler/lexical-model.js
npm notice 158B dist/util/min-keyman-version.js
npm notice 4.5kB dist/model-info-compiler/model-info-compiler.js
npm notice 57B dist/lexical-model-compiler/model-info-file.js
npm notice 341B dist/lexical-model-compiler/stub.js
npm notice 115B dist/util/sysexits.js
npm notice 2.1kB dist/util/util.js
npm notice 1.4kB package.json
npm notice 1.0kB README.md
```
For every release of **Keyman Developer**, the CI publishes a release of
`@keymanapp/lexical-model-compiler`. The version number is locked with
the particular version of Keyman Developer.
### `set_npm_version`
This helper function sets the version in the `package.json` for the
given package, according to the VERSION_WITH_TAG variable.
```bash
. $KEYMAN_REPOSITORY_ROOT/resources/shellHelperFunctions.sh
set_npm_version
```
