Version config file

by default , all providers uses the latest version, but you can add a file call .tfcompleterc under working directory, and content can be this:

vsphere=1.0.3
aws=0.1.0

using the syatax of <provider>=<version>

Demo:

Community Providers

By default no community providers is enable, to use one, first refer to COMMUNITY_PROVIDER_VERSIONS.md , then add a .tfcompleterc to your current working dir , for ex. to use Generic REST Api Provider, the .tfcompleterc would look like

restapi=master

Specific Providers

Google Beta Provider

To use completion for google beta provider, please use .tfcompleterc and put google=beta_<version>

General Todo

• Adapt to Upcoming terraform 0.10
• Added a bot for auto pushing of new provider version
• (WIP) Refactoring Regex for linter and completion, and Trying out on api based(so it can integrade with other editor) solution
• (WIP) More test cases
• Support for Neomake(Require further testing)
• Run terraform plan and output to a new window(<leader>rr)
• Async Run support(For Neovim/Vim 8)
• Move regex code to a json(for easier extension)
• Test from zero to useful setup using Docker
• Jump Reference (Ctrl-L first time to jump to resource definition, second time
  on the same line to jump back)
• Show Doc (Ctrl-K)
• Provide config and example
• Integrate Basic terraform validate and tflint into Synstatic
• Added a custom linter for providing a better error
• (WIP) Better linter
• (WIP) Full Snippets

NOTE: enabling deep check for tflint can be a bit slow

NOTE: To use tffilter please add export PATH=$PATH:/path/to/this/plugin/bin to your bashrc or zshrc

Demo of the linter

Todo for Terraform completion

• (Require more work) Lookup Attributes data using terraform.tfstate
• Evaluate Interpolation
• (WIP) Custom Provider completion, might do Rest API style due to unstable custom provider
• Provider
• Completion for functions(file,etc) and basic resource arguments(count,lifecyle, etc)
• Module (Make sure you run terraform get beforehand)
• Data
• Resource(with Provider)
• Parameter
• Adding Info to Argument and Attribute(Type not including ,since Info
  already indicate it)
• Variable
• Cleaner code
• local/offline
• Add completion tags, ingress, and other subblock
• Further seperate data source from resource

Todo for HCL

• Add Completion for hcl
• Completion for Sublock(Indicate by Type(B) )

Todo for Improvement

• Add Travis-CI for testing, and ensuring the completion is outputing the right completion
• Look into the new module registry (Now support module name completion)
• Add config for allowing multiple version for providers
