# Bosh Deployment Manifest Editor for Theia IDE
|
||||
|
||||
This extension provides validation, content assist and documentation hovers
|
||||
for editing [Bosh](https://bosh.io/) Deployment Manifest files and
|
||||
Cloud Configs.
|
||||
|
||||
## Functionality
|
||||
|
||||
### Validation
|
||||
|
||||
As you type the text is parsed and checked for basic syntactic and structural correctness. Hover over
|
||||
an error marker to see an explanation:
|
||||
|
||||

|
||||
|
||||
### Content assist
|
||||
|
||||
Having trouble remembering all the names of the attributes, and their spelling? Or can't remember
|
||||
the exact name/version of the stemcell you just uploaded to your bosh environment? Content assist
|
||||
to the rescue:

|
||||
read its detailed documentation:
|
||||
|
||||

|
||||
|
||||
### Goto Symbol in File
|
||||
|
||||
Is your Deployment Manifest getting larger and is it becoming harder to find a particular Instance Group,
|
||||
Release, or Stemcell definition? The "Goto Symbol in File" command helps you quickly jump to a specific
|
||||
definition.
|
||||
|
||||
Type `CTRL-SHIFT-O` to popup a list of all symbols in your current file. Start typing a name
|
||||
(or portion thereof) to narrow down the list. Select a symbol to jump directly to its location in the
|
||||
file.
|
||||
|
||||
![Goto Symbol Screenshot][goto_symbol]
|
||||
|
||||
### Goto/Peek Definition
|
||||
|
||||
Use "Goto Defition" or "Peek Definition" to quickly go (or peek) from a Release or Stemcell name
|
||||
to its corresponding definition.
|
||||
|
||||
![Peek Definition Screenshot][peek]
|
||||
|
||||
### V2 versus V1 Schema
|
||||
|
||||
The editor is intended primarily to support editing manifests in the [V2 schema](https://bosh.io/docs/manifest-v2.html).
|
||||
When you use attributes from the V1 schema the editor will detect this however and switch to 'V1 tolerance' mode.
|
||||
|
||||
In this mode, V1 properties are accepted but marked with deprecation warnings and V2 properties are marked as (unknown property)
|
||||
errors.
|
||||
|
||||
## Usage
|
||||
|
||||
### Activating the Editor
|
||||
|
||||
The Bosh editor automatically activates when the name of the `.yml` file you are editing
|
||||
follows a certain pattern:
|
||||
|
||||
- `**/*deployment*.yml` : activates support for Bosh manifest file.
|
||||
- `**/*cloud-config*.yml` : activates support for Bosh cloud config.
|
||||
|
||||
### Targetting a specific Director
|
||||
|
||||
Some of the Validations and Content Assist depend on information dymanically retrieved from an active Bosh director.
|
||||
The editor retreives information by executing commands using the Bosh CLI. For this to work the CLI (V2
|
||||
CLI is required) and editor have to be installed and configured correctly.
|
||||
|
||||
There are two ways to set things up to make this work:
|
||||
|
||||
#### Explicitly Configure the CLI:
|
||||
|
||||
The bosh cli is configured by specifying keys of the form `bosh.cli.XXX`. These can be specified in the Theia preference
|
||||
file (`~/.theia/settings.json`).
|
||||
|
||||
Note that the `bosh.cli.XXX` settings do not allow you to provide credentials to connect to the director.
|
||||
The editor assumes that you are providing the credentials implicitly by using the `bosh login` command from a terminal.
|
||||
The bosh cli will persist the credentials in `~/.bosh/config` and read them from there. A typical sequence of commands
|
||||
to store the credentials would be something like the following:
|
||||
|
||||
First, create an alias for your environment:
|
||||
|
||||
```
|
||||
$ bosh alias-env my-env -e 10.194.4.35 --ca-cert <(bosh int ./creds.yml --path /director_ssl/ca)
|
||||
Using environment '10.194.4.35' as anonymous user
|
||||
...
|
||||
Succeeded
|
||||
$
|
||||
```
|
||||
|
||||
Second, obtain username/password for your director. For example:
|
||||
|
||||
```
|
||||
$ bosh int ./creds.yml --path /admin_password
|
||||
very-secret-admin-password
|
||||
|
||||
Succeeded
|
||||
```
|
||||
|
||||
Now use `bosh login` to establish a session and store the credentials:
|
||||
|
||||
```
|
||||
$ bosh login -e my-env
|
||||
Username (): admin
|
||||
Password (): very-secret-admin-password
|
||||
|
||||
Using environment '10.194.4.35' as client 'admin'
|
||||
|
||||
Logged in to '10.194.4.35'
|
||||
|
||||
Succeeded
|
||||
```
|
||||
|
||||
You can verify that CLI is setup correctly by executing a command like:
|
||||
|
||||
```
|
||||
$ bosh -e my-env cloud-config
|
||||
...
|
||||
Succeeded
|
||||
```
|
||||
|
||||
#### Implictly Configure the CLI:
|
||||
|
||||
If the bosh cli is not explicitly configured, the editor will, by default, try to execute commands like `bosh cloud-config --json`
|
||||
and `bosh stemcells --json` without an explicit `-e ...` argument. This works only if you ensure that the editor
|
||||
process executes with a proper set of OS environment variables:
|
||||
|
||||
- `PATH`: must be set so that `bosh` cli executable can be found and refers to the V2 CLI.
|
||||
- `BOSH_ENVIRONMENT`: must be set to point to the bosh director you want to target.
|
||||
|
||||
If you start Theia from a terminal, you can verify that things are setup correctly by executing command:
|
||||
|
||||
bosh cloud-config
|
||||
|
||||
If that command executes without any errors and returns the cloud-config you expected, then things are setup correctly.
|
||||
If you subsequently launch Theia from that same terminal the dynamic CA and linting should work correctly.

# Cloud Foundry Manifest Editor for Theia IDE
|
||||
|
||||
This extension provides basic validation, content assist and hover infos
|
||||
for editing Cloud Foundry [Manifest](https://docs.cloudfoundry.org/devguide/deploy-apps/manifest.html) Files.
|
||||
|
||||
## Usage
|
||||
|
||||
The CF manifest editor automatically activates when the name of the `.yml` file you are editing,
|
||||
matches the glob pattern: `manifest*.yml`.
|
||||
|
||||
## Functionality
|
||||
|
||||
### Validation
|
||||
|
||||
As you type the manifest is parsed and checked for basic syntactic and structural correctness. Hover over
|
||||

|
||||
|
||||
### Dynamic Cloud Foundry Content Assist
|
||||
|
||||
Would you like to see actual Cloud Foundry values for attributes like `services`, `buildpack`, `domain`, and `stack`? If you have [cf CLI](https://docs.cloudfoundry.org/cf-cli/) installed and connected to a Cloud target, the extension will automatically display values for certain manifest attributes.
|
||||
|
||||
For example, if you are connected to a Cloud target that has services, and you invoke content assist in an entry under `services`, you will see the available service instances. In addition, service instances that do not exist in the Cloud target, like `redisserv` in the example below, are highlighted with a warning.
|
||||
|
||||
Dynamic content assist also shows which Cloud target you are connected to.

# Spring Boot Application Support for Theia IDE
|
||||
|
||||
Theia extension and Language Server providing support for working with Spring Boot
|
||||
`application.properties`, `application.yml` and `.java` files.
|
||||
|
||||
# Usage:
|
||||
|
||||
The extension will automatically activate when you edit files with the following
|
||||
name patterns:
|
||||
|
||||
- `application*.properties` => activates support for Spring Boot properties in `.properties`format.
|
||||
- `application*.yml` => activates support for Spring Boot properties in `.yml` format.
|
||||
- `*.java` => activates Spring Boot specific support editing `.java` files.
|
||||
|
||||
# Functionality for `.java`
|
||||
|
||||
## Navigating the source code - Go to symbol in file/workspace
|
||||
Easy navigation to Spring-specific elements of your source code.
|
||||
|
||||
![Go to Symbol in workspace][java-navigation]
|
||||
|
||||
### Shortcuts
|
||||
* Mac: Cmd-Shift-O (symbols in file), Cmd-T (symbols in workspace)
|
||||
* Linux/Windows: Ctrl-Shift-O (symbols in file), Ctrl-T (symbols in workspace)
|
||||
|
||||
### Examples
|
||||
* `@/` shows all defined request mappings (mapped path, request method, source location)
|
||||
* `@+` shows all defined beans (bean name, bean type, source location)
|
||||
* `@>` shows all functions (prototype implementation)
|
||||
* `@` shows all Spring annotations in the code
|
||||
|
||||
## Quick-access for running apps
|
||||
Easy navigation to the provided request mappings of running apps.
|
||||
|
||||
![accessing running apps quickly][java-live-apps-quick-access]
|
||||
|
||||
### Shortcuts
|
||||
* Mac: Cmd-Shift-O (symbols in file), Cmd-T (symbols in workspace)
|
||||
* Linux/Windows: Ctrl-Shift-O (symbols in file), Ctrl-T (symbols in workspace)
|
||||
|
||||
### Examples
|
||||
* `//` shows all request mappings of all running Spring Boot apps and opens a browser for the selected endpoint
|
||||
|
||||
## Live application information hovers
|
||||
Show information from running Spring Boot apps on your machine in the source code. This allows you to run the Spring Boot app locally on your machine and visualizes information from those running apps in your source code.
|
||||
|
||||
### Visualization
|
||||
Once the tooling detects a running Spring Boot app on your local machine, it automatically shows hints in the source code where data from the running app can be inspected. Then hovering over that area (with the mouse pointer), the data from the running app shows up.
|
||||
|
||||
If there are multiple instances of the app running on your machine, the live data from all those instances will show up in the hover information.
|
||||
|
||||
![live data from running apps as hover on source code][java-live-hovers]
|
||||
|
||||
### Examples
|
||||
