Hi there! Thanks for making this awesome tool. I see integration with Syntastic is possible, but what about ale? Is this currently possible?

I have installed ghdl and vundle, and then vim-hdl and syntastic. So far tags and syntax are properly highlighted, and errors are reported as expected running SyntasticCheck (or just modifying and saving files). But each time I open an vhd file with vim, this message appears:

Error detected while processing BufEnter Auto commands for "*.vhd":
No handlers could be found for logger "vimhdl.vim_client"
Press ENTER or type command to continue

I'm using vim 7.4 on up-to-date ArchLinux.

When starting vim I get following error:
Error detected while processing function vimhdl#setup..<SNR>73_Pyeval: line 2: Traceback (most recent call last): File "<string>", line 1, in <module> File "/home/abyszuk/.vim/bundle/vim-hdl/python/vimhdl/vim_client.py", line 87, in startServer self._waitForServerSetup() File "/home/abyszuk/.vim/bundle/vim-hdl/python/vimhdl/vim_client.py", line 162, in _waitForServerSetup reply = request.sendRequest() File "/home/abyszuk/.vim/bundle/vim-hdl/python/vimhdl/base_requests.py", line 89, in sendRequest requests.packages.urllib3.exceptions.NewConnectionError) as exc: AttributeError: 'module' object has no attribute 'NewConnectionError' E858: Eval did not return a valid python object

I use quite standard install of CentOs 7. Python version 3.3

Some nice to haves:

• Support for wildcards on paths
• Support for escaping line breaks
• Syntax checker for the project file (big maybe...)

Hi, vim-hdl tool seems to be perfect and I am very excited to try it. When starting vim with a vhd file, following error is reported.

Error detected while processing function vimhdl#setup[10]..59_startServer[6]..59_pyEval:
line 4:
Traceback (most recent call last):
File "", line 1, in
File "D:\programs\gVimPortable\App\vim\plugins\vim-hdl-master\python\vimhdl\vim_client.py", line 100, in startServer
self._startServerProcess()
...
...
...

My setup is as follows:

• Windows,
• python3.7 64 bits.
• No internet connection

I installed hdlcc package to python. In anaconda prompt, when hdlcc is run, hdlcc server starts to run.

To install vim-hdl, the zip file of the repository is extracted and the following code is added to vimrc.

set runtimepath+=$VIM\plugins\vim-hdl-master

I checked previous issues and realized that there was no Windows support (by March 26,2018).

My questions are

• Is there a support for windows now?
• If yes, what would you suggest me to solve it?

Thank you for your time.

Given a configured project and a project file named project.prj, the steps to reproduce are

1. Build the project with hdlcc/runner.py

   runner.py <path/to/project/file> --clean --build

2. Wait for the build to finish. There should be a filename called
   .project.prj, which is the cached info of the project file

3. Launching Vim and to a source inside the project gives the following error

$ vim <path/to/source>
Vim: Caught deadly signal SEGV
  File
  "<path/to/vim-hdl>/autoload/../dependencies/hdlcc/hdlcc/project_builder.py",
  line 287, in _recoverCacheVim: Finished.

      cache = pickle.load(open(cache_fname, 'r'))
      AttributeError: 'module' object has no attribute
      'StandaloneProjectBuilder'
      Segmentation fault

Error is slightly different if the file is opened with gVim

$ gvim <path/to/source>
[xcb] Unknown request in queue while dequeuing
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been
called
[xcb] Aborting, sorry about that.
vim: ../../src/xcb_io.c:179: dequeue_pending_request: Assertion
`!xcb_xlib_unknown_req_in_deq' failed.
Vim: Caught deadly signal ABRT

Brainstorm of topics:

• g:vimhdl_conf_file, b:vimhdl_conf_file
• vimhdl sorting method
• Version
• Debug info

Vim-hdl configuration should be done within Vim. Currently this is done via python/config.py

hdlcc is pure Python, so using https://github.com/warner/python-versioneer is easy. Vim-hdl should have a similar alternative.

Selecting the quickfix and pressing Enter to jump to the problematic line yields E926.

From Vim help:

*E925* *E926*
If the current quickfix or location list was changed by an |autocommand| while
processing a quickfix or location list command, it will be aborted.

Given a project built with a previous version of Vim (probably 9a8a6ae), opening it after upgrading to 870c8f8 crashes Vim.

This probably depends on hdlcc issue 4 (Fix project persistency implementation) issue being resolved first.

Vim log with -V15 is here: vim-hdl-issue.log.zip

When Vim is opened, vim_client.VimhdlClient.setup is run in a thread and calls to vim_client.VimhdlClient.buildByPath are locked until setup completes.

• Implement a database inside project_builder.ProjectBuilder, taking into account errors (currently this is ignored)
• Allow vim_client.VimhdlClient.buildByPath to be run while vim_client.VimhdlClient.buildByDependency is active
• Shell calls called by compilers.base_compiler.BaseCompiler must be queued to avoid consistency errors by the compiler (it may not handle multiple threads accessing its internal DB)

Expected result:

• Open Vim with nothing built (this will trigger background build)
• While the build is running, build the current file
  • If dependencies have already been built, build it
  • If dependencies haven't been built, warn the user (don't wait until dependencies are met)

I loaded syntastic and vim-hdl using native method of vim, and try to get the vim-hdl-examples/msim.prj running.

My .vimrc includes:

" Syntastic recommended settings

" vim-hdl
let g:vimhdl_conf_file = '/home/user/vim-hdl-examples/msim.prj'
let g:syntastic_vhdl_checkers = ['vimhdl']

When I open the file vim-hdl-examples/another-library/foo.vhd , I get the following error output:

Error detected while processing CursorMoved Auto commands for "*.vhd":

When I run hdlcc standalone, I do not get any errors.

Built-in libraries are statically defined, which means that things will break on different environments. We can either use the compiler to get them somehow or create an option for the user to set manually. Using the compiler is the preferred approach.

Tested with grlib lib/tech/ec/orca/orca.vhd and even after the project builds fine, there is nothing on the location list.

hdlcc logs look fine, but since the file is large (27k lines), the hdlcc client is probably timing out.

The client might need to continue in background if a timeout occurs, but the location list can only be updated synchronously. At least the user should be warned when a timeout occurs

A full rebuild is currently needed when changing the configuration file. Implement runtime configuration file reloading.

Some tests like https://travis-ci.org/suoto/vim-hdl/jobs/133960177 failed because vroom scripts don't wait until the project has finished building. One possible solution is to add something like a VimhdlWaitForBuild command.

Project build code should be on its own repository to allow creating plugins for other text editors

vim-hdl should bundle the six package as a dependency is feasible

The official distribution of Python 3 for Windows has the executable name python instead of python3. Normally vim can work with it, and echo has("python3") returns 1. But it will cause a FileNotFoundError in this plugin. Changing the executable of Python to python3 can solve this problem.

I get the following error

"vimhdl.vim" 201L, 7227C
Error detected while processing function vimhdl#setup..<SNR>44_setupPython:

vim-hdl has been added to vim.org so installing from there should be tested.
