Hog Emacs

A collection of functions for working with Hog (https://hog.readthedocs.io) projects from emacs.

hog-open-project	Open a Hog project in Vivado
hog-launch-impl	Launch Implementation
hog-launch-synthesis	Launch Synthesis
hog-launch-workflow	Launch Full Workflow
hog-follow-link-at-point	Follow a link in a Hog src file
hog-expand-glob-at-point	Expand a “*” glob in a Hog src file

It also includes facilities for creating configuration files from Hog projects for various HDL language servers:

• hog-vhdl-ls-create-project-toml
• hog-ghdl-ls-create-project-json
• hog-vhdl-tool-create-project-yaml

Additionally, hog-emacs now supports insertion of Vivado templates. They are scrubbed from the XML source found in your vivado path.

• hog-insert-vhdl-template
• hog-insert-verilog-template
• hog-insert-systemverilog-template
• hog-insert-xdc-template

Some miscellaneous functions are included as well:

• hog-clean-vivado-xci: cleans the output products associated with Vivado XCI files

This package also includes a major mode which provides syntax highlighting for Hog source files, and enables the M-RET key to follow files as links.

With flycheck installed it will also provide error indicators for files with broken links.

You should customize these variables to your liking, e.g.

(setq hog-vivado-path        "/opt/Xilinx/Vivado/2020.2"
      hog-number-of-jobs     4
      hog-template-cache-dir "~/.emacs.d/")

Configuration variables can be set on a per-project basis, e.g. by adding the following to .dir-locals.el.

((nil . ((hog-vivado-path . "/storage/Xilinx/Vivado/2020.1"))))

To have flycheck integration please add the following snippet to your configuration.

(flycheck-define-checker
    hog-src-checker
  "Checker for Hog source files"

  :command ("emacs" (eval flycheck-emacs-args)
            "--load" (eval (file-name-sans-extension (locate-library "hog")))
            "--visit" source-inplace
            "-f" "hog-check-src-file")

  :error-patterns
  ((error line-start "Error:" line " " (message) line-end)
   (info line-start "Info:" line " " (message) line-end)
   (warning line-start "Warning:" line " " (message) line-end))
  :modes (hog-src-mode))
