This is vim-metamath, a vim mode to help edit metamath files. Metamath is a tiny language that can express theorems in abstract mathematics, accompanied by proofs that can be rigorously verified by a computer program. Vim-metamath is a vim mode that provides immediate feedback while you're editing metamath files using the widely-used vim text editors. This mode should help you detect and fix defects before you even save your file. It is Free / libre / open source software, released under the MIT license.
Unlike marnix/metamath.vim mode, this vim mode is much more ambitious and strives to differentiate many different things. For example, it specially highlights different kinds of comments inside a comment area, and it colorizes certain operators differently. This creates a lot of visual differentiation that makes it easier to distinguish different kinds of information.
This is version 1.0.2. This project adheres to Semantic Versioning.
You can download final releases in zip or tar.gz formats from the releases area. Expand it, and in a terminal window "cd" into its directory.
You can also download using git by running this in a terminal window:
git clone https://github.com/david-a-wheeler/vim-metamath.git
cd vim-metamathThis will get the current released version (in the "master" branch). To get the development version, then do "git checkout develop".
On Unix/Linux (including MacOS), run "make install" to install it (this is a standard convention for installing files). You're done!
On Windows, do the following:
mkdir "%userprofile%\vimfiles"
mkdir "%userprofile%\vimfiles\ftdetect" "%userprofile%\vimfiles\syntax"
copy "vim\ftdetect\\*.*" "%userprofile%\vimfiles\ftdetect"
copy "vim\syntax\\*.*" "%userprofile%\vimfiles\syntax"If you're an advanced user, read on.
Running "make install" doesn't do any serious magic; it just copies the files and directories from this mode's "vim/" directory to your local vim files directory "~/.vim" (creating directories as needed). If you can't run make, feel free to directly create the necessary directories and copy the files directly.
Advanced users can run make with additional parameters that set VIMDIR (the vim files directory to install to), and/or CP_OPTIONS (additional options for "cp" when copying). The Makefile respects the DESTDIR convention (a prefix to the installation directory that you can pass via an environment variable or make parameter). You can also run "make uninstall" to uninstall the files. Here's an example:
make VIMDIR="${HOME}/.vim-alt".
Here are a few screenshots. Note that vim-metamath and vim are extremely configurable, so you can make your display look very different if you want it to. By default this mode uses a range of different colors to maximize feedback (which can help you avoid defects).
These screenshots show the set.mm file while it's being edited. This is typically processed and turned into HTML pages for viewing. For example, see the Metamath page for df-an (definition of "and"). Theorem *4.64 of Whitehead and Russell. Detailed proofs are often created by other tools and turned into compressed form shown here.
