TLA+ tools for Emacs
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.
Press C-c C-c for a menu of commands.
The command tla-create-tlc-config-file (C-c C-c c) creates an empty
configuration file for TLC, with placeholders for constants, the INIT and NEXT
equation, and any invariants.
C-c C-c m starts the TLC model checker with the last selected configuration
file. To select a configuration file before running TLC, press C-c C-c -m m.
Press -d before m to toggle deadlock checking.
C-c C-c t translates PlusCal and selects the created configuration file.
C-c C-c p creates a PDF version of the current file.
The menu commands expect tla-bin to be
installed and pcal, tlc and tlatex to be in the path.
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>.
- 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.)
- 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.
