tla-tools
TLA+ tools for Emacs
tla-pcal-mode
tla-pcal-mode is a mixed mode for editing TLA+ and PlusCal source
files. It depends on polymode.
It supports the p-syntax for PlusCal, not the c-syntax.
A basic TLA+ auto-insert template is provided.
Usage
Compilation-mode helper
Add the source directory to load-path and M-x load tla-tools. Or
just eval the buffer.
Execute M-x tla-tools-error-regexp-add to add regexps for
compilation mode.
Using tla-bin, a TLA+ source file
can be checked with M-x compile, with a compile command of tlc <tla-file> or pcal <tla-file> && tlc <tla-file>.
Bugs
- Doesn't implement much except helping next-error/previous-error.
- No support TLC reports errors just with the module name, the filename is guessed to be modulename.tla. Sany errors don't have the module name either (makes sense, it's syntax checking the file), so it's guessed from the "Parsing file ..." line. Multiple "Parsing file" lines could lead the errors to the wrong file. As a hack, there's a super ugly regexp which prevents matching filenames beginning with "/private/", which is where the temp files go on my installation. Sorry if you need to check /tmp instead, maybe the test function offers you some inspiration.
- Error type (warning, error) is not guessed.
- No extra support for "-tool" option (which makes tlc emit tool-readable messages.)
- tlc requires a config file, and this package does nothing to help generate it.
- It would be nice if it auto reverted the buffer after pcal (which
rewrites the tla file.) Until something nicer is done, I'm using
auto-revert-mode. Alternatively check out tlaplus-cli-template which keeps your source clean and puts the pcal translations into atarget/directory.
