The HOL Light theorem prover
License: Other
HOL LIGHT HOL Light is an interactive theorem prover / proof checker. It is written in Objective CAML (OCaml) and uses the toplevel from OCaml as its front end. This is the HOL Light homepage: http://www.cl.cam.ac.uk/~jrh13/hol-light/index.html and this is the root of the Github code repository: https://github.com/jrh13/hol-light Basic installation instructions are below. For more detailed information on usage, see the Tutorial: http://www.cl.cam.ac.uk/~jrh13/hol-light/tutorial.pdf Refer to the reference manual for more details of individual functions: http://www.cl.cam.ac.uk/~jrh13/hol-light/reference.html (HTML files) http://www.cl.cam.ac.uk/~jrh13/hol-light/reference.pdf (one PDF file) * * * * * * * * INSTALLATION The Objective CAML (OCaml) implementation is a prerequisite for running HOL Light. HOL Light should work with any recent version of OCaml; I've tried it on at least 3.04, 3.06, 3.07+2, 3.08.1, 3.09.3, 3.10.0, 3.11.2, 4.00, 4.05 and 4.14. 1. OCaml: there are packages for many Linux distributions. For example, on a debian derivative like Ubuntu, you may just need to do the following: sudo apt-get install ocaml Alternatively you can download binaries directly, or get sources and build them (which in my experience is usually trouble-free). See the OCaml Web page for downloads and other information. http://caml.inria.fr/ocaml/index.en.html 2. Dependencies: HOL Light uses camlp5 and zarith (num for OCaml version < 4.14). If you have OPAM installed on your machine, running the following command inside this directory will create a local OPAM switch which uses the latest OCaml version that fully supports features of as well as all dependencies installed: make switch eval $(opam env) To manually install dependencies, the DEPENDENCIES chapter of this document explains it. Now for HOL Light itself. The instructions below assume a Unix-like environment such as Linux [or Cygwin (see www.cygwin.com) under Windows], but the steps automated by the Makefile are easy enough to invoke manually. There's more detail on doing that in the Tutorial. (0) You can download the HOL Light sources from the Github site. For example, the following will copy the code from the trunk of the Github repository into a new directory 'hol-light': git clone https://github.com/jrh13/hol-light.git The above is now the recommended way of getting HOL Light. There are also gzipped tar files on the HOL Light Web page, but they are only for quite old versions and will probably be difficult to use with recent versions of OCaml. You should next enter the 'hol-light' directory that has been created: cd ./hol-light There are now two alternatives: launch the OCaml toplevel and directly load the HOL Light source files into it, or create a standalone image with all the HOL Light sources pre-loaded. The latter is more convenient, but requires a separate checkpointing program, which may not be available for some platforms. First the basic approach: (1) Do 'make'. This ought to build the appropriate syntax extension file ('pa_j.cmo') for the version of OCaml that you're using. If you have the camlp4 or camlp5 libraries in a non-standard place rather than /usr/local/lib/ocaml/camlp4 or /usr/local/lib/ocaml/camlp5 then you may get an error like this Error while loading "pa_extend.cmo": file not found in path. in which case you should add the right directory to CAMLP4LIB or CAMLP5LIB, e.g. export CAMLP5LIB=$HOME/mylib/ocaml/camlp5 (2) If you are using a Unix-like environment, simply run `./hol.sh`. This should rebuild all the core HOL Light theories, and terminate after a few minutes with the usual OCaml prompt, something like: Camlp5 parsing version (HOL-Light) 8.02.00 # HOL Light is now ready for the user to start proving theorems. If you are not using a Unix-like environment, do 'ocaml'. (Actually for OCaml >= 4.02 I prefer 'ocaml -safe-string' to avoid mutable strings, while you may need something else like 'ocamlnum' on some platforms --- see [*] below.) If you are using OCaml 4.14, you need to create a top-level OCaml using 'ocamlmktop -o ocaml-hol' and use 'ocaml-hol' because the default 'ocaml' does not have 'compiler-libs' that is necessary to run HOL Light. At the OCaml prompt '#', do '#use "hol.ml";;' (the '#' is part of the command, not the prompt) followed by a newline. You can also use the load process (2) in other directories, but you should either set the environment variable HOLLIGHT_DIR to point to the directory containing the HOL source files, or change the first line of "hol.ml" to give that explicitly, from let hol_dir = ref (try Sys.getenv "HOLLIGHT_DIR" with Not_found -> Sys.getcwd());; to, for example let hol_dir = "/home/johnh/hol-light";; or let hol_dir = "/usr/share/hol";; Now for the alternative approach of building a standalone image. The level of convenience depends on the checkpointing program you have installed. As of 2024, there are three programs you can use. (1) DMTCP: you can download from here: https://github.com/dmtcp/dmtcp/releases To build DMTCP, please refer to https://github.com/dmtcp/dmtcp/blob/master/INSTALL.md . HOL Light does not have convenient commands or scripts to exploit DMTCP, but you can proceed as follows: 1. Start ocaml running under the DMTCP coordinator: dmtcp_launch ocaml 2. Use ocaml to load HOL Light as usual, for example: #use "hol.ml";; 3. From another terminal, issue the checkpoint command: dmtcp_command -kc This will kill the ocaml process once checkpointing is done. 4. Step 3 created a checkpoint of the OCaml process and a shell script to invoke it, both in the directory in which ocaml was started. Running that should restore the OCaml process with all your state and bindings: ./dmtcp_restart_script.sh (2) CRIU: CRIU is similar to DMTCP but faster. However, it requires sudo priviledge depending on your environment (e.g., WSL2). you can download from here: https://criu.org/Download/criu To build CRIU, please refer to https://criu.org/Installation . To checkpoint, 1. Start ocaml process and load HOL Light. 2. From another terminal, run criu dump -o dump.log -t <ocaml process id> --shell-job 3. To restore, run criu restore -o restore.log --shell-job Please refer to https://criu.org/Simple_loop for details. (3) selfie: This is a convenient OCaml checkpointing tool developed by Quentin Carbonneaux. Please git clone git://c9x.me/selfie.git and run `make selfie.cma` from the directory. Open ocaml and run # #load "selfie.cma";; # #use "selfie.ml";; Now you can use `snap "output.img";;` to checkpoint the process. The directories "Library" and "Examples" may give an idea of the kind of thing that might be done, or may be useful in further work. Thanks to Carl Witty for help with Camlp4 porting and advice on checkpointing programs. * * * * * * * * DEPENDENCIES 1. zarith or num: The HOL Light system uses the OCaml "Num" library or "Zarith" library for rational arithmetic. If OCaml 4.14 is used, HOL Light will use Zarith. You can install it using the OCaml package manager "opam" by opam install zarith If OCaml 4.05 is used, HOL Light will use Num which is included in the core system. If you are using an OCaml version between 4.06 and 4.13, Num must be installed separately because it is no longer included in the core system. You can use "opam" by opam install num Alternatively you can download the sources from here https://github.com/ocaml/num and build and install them following the instructions on that page, for example git clone https://github.com/ocaml/num mynums cd mynums make all sudo make install [assuming no earlier errors] 2. camlp5: this is needed to run HOL Light under any OCaml >= 3.10. Somtimes you need a recent version of camlp5 to be compatible with your OCaml. For example, OCaml 4.05 is compatible with camlp5 7.10 and OCaml 4.14 is compatible with camlp5 8.02. I recommend downloading the sources for a recent version from https://github.com/camlp5/camlp5/releases ('tags' tab has full series) and building it in "strict" mode before installing it, thus: cd software/camlp5-rel701 [or wherever you unpacked sources to] ./configure --strict make sudo make install [assuming no earlier errors] There are also packages for camlp5, so you may be able to get away with just something like sudo apt-get install camlp5 or opam pin add camlp5 <version (e.g., 7.10 for ocaml 4.05)> However, you may get a version in "transitional" instead of "strict" mode (do "camlp5 -pmode" to check which you have). * * * * * * * * [*] HOL Light uses the OCaml 'num' library for multiple-precision rationals. On many platforms, including Linux and native Windows, this will be loaded automatically by the HOL root file 'hol.ml'. However, OCaml on some platforms (notably Cygwin) does not support dynamic loading, hence the need to use 'ocamlnum', a toplevel with the 'num' library already installed. You can make your own with: ocamlmktop -o ocamlnum nums.cma

,
the assumption ~(cos(x + y) = &0) seems unnecessary.
Here's a patch to the print_to_string function that accesses the current line
length using a call to get_margin before printing the argument to a string. I
also recoded the print_to_string function in terms of ocaml buffers, instead of
a string reference.

LIM_CONG_WITHIN has an extra antecedent since 90f37b2, which is missing in the statement of the theorem in https://github.com/jrh13/hol-light/blob/master/Multivariate/flyspeck.ml#L7086. The rule ends up getting filtered out entirely from basic_congs().
For example:
utop # t1;;
- : term = `\x. s x`
utop # x1, type_of x1;;
- : term * hol_type = (`x`, `:A->bool`)
utop # let s1 = frees t1 |> hd;;
val s1 : term = `s`
utop # instantiate (term_match [] s1 x1) t1;;
- : term = `\x. x x`
The last term is semantically (and type-wise) okay but will not be accepted by the parser (even with explicit type annotations). The reason is that the two x
s have different types so the bound variable is not renamed. On the other hand the following sequence produces the correct renaming:
utop # t2;;
- : term = `\x. s + x`
utop # x2, type_of x2;;
- : term * hol_type = (`x`, `:num`)
utop # let s2 = frees t2 |> hd;;
val s2 : term = `s`
utop # instantiate (term_match [] s2 x2) t2;;
- : term = `\x'. x + x'`
I installed OCaml 4.00.0 and camlp5 using GODI a while back. Today, I checked
out the hol-light sources, but when I tried building them I got the following
error:
File "pa_j.ml", line 13, characters 0-10:
Error: Unbound module Pcaml
make: *** [pa_j.cmo] Error 2
After a bit of searching, I found that ocamlc treats the `-I +foo` argument as
`-I /usr/lib/ocaml/foo`:
http://stackoverflow.com/questions/3848897/unbound-modules-in-ocaml
As it turns out, GODI installs camlp5 in a non-standard location. On this
machine (Ubuntu 12.04.1 x86), `which camlp5` returns:
/opt/godi/bin/camlp5
So, I tweaked the Makefile a bit to make it more robust (see the attached
diff). camlp4 and camlp5 both support the "-where" option, so I've used that
within backticks along with the -I option when invoking ocamlc. This makes it
so camlp4/camlp5 will be included properly no matter where it's installed on
the system.
Cheers,
Jack

Hello,
hol-light fails with camlp5 7.11 because of a change in its AST. In Debian, I had to apply the following patch to make the package compile again:
I changed pa_j_4.xx_7.xx.ml directly, but probably a new pa_j_xx.ml should be created, and the logic for picking the right pa_j.ml adapted.
Cheers,
Stéphane

I'm not familiar with the Ocaml tool-chain. Following the instructions in the README, I got the following problem:
$ make
$ ocaml

val hol_version : string = "2.20++"
val hol_dir : string ref = {contents = "/home/asr/src/hol-light"}
val temp_path : string ref = {contents = "/tmp"}
Cannot find file camlp5o.cma.
- : unit = ()

From this and this comments (I don't know in which language these comments were written), I could fix my problem by running
$ ocaml -I `camlp5 -where` camlp5o.cma
instead of
$ ocaml
Is there something missing in the Makefile?
$ ocaml --version
The OCaml toplevel, version 4.03.0
$ camlp5 -v
Camlp5 version 6.16 (ocaml 4.03.0)
What steps will reproduce the problem?
1. Install OCaml 3.12.0 on Mac OS X 10.5.8 from prebuilt binaries
2. Download camlp5-6.02.2, apply two patches, and build.

What version of the product are you using? On what operating system?
Revision 83 on Mac OS 10.5.8.
Please provide any additional information below.
Can you tell me a combination of a version of HOL Light and a version of camlp5
that work together? I had other problems when I tried building the 10 Jan 2010
snapshot you have on the HOL Light home page.

This causes user pretty-printers to print directly to the console, instead of
the correct destination known to the formatter (e.g., a target string in
string_of_term).
I attach a patchfile that fixes this that can be applied using the command
patch -p0 < patchfile
Note: it changes the type of user pretty-printers by adding the formatter as an
argument, so existing user pretty-printers will need to be updated.

I got similar errors in these two environments:
cd hol-light && make
cp: cannot stat ‘pa_j_3.1x_8.xx.ml’: No such file or directory
make: *** [Makefile:67: pa_j.ml] Error 1
The error seems related to #7
Documentation for GEN_REWRITE_TAC seems to be copied from HOL4, but in HOL
Light this tactic takes only two arguments, not three. Patch attached.

I've tried running make clean first, but no joy. My system runs Fedora 23, and my ocamlc version is 4.02.2, from the Fedora repository. I'm using hol-light master branch, commit c9ee18f.
All the best,
James.
Hello. Using ocaml.4.02.3 and campl5.6.17 I get the following problem:
#use "hol.ml";;
# module OrdInt = struct type t = int let compare = (-) end;;
Toplevel input:
# module OrdInt = struct type t = int let compare = (-) end;;
^^^^^^
Parse error: 'type' or 'rec' expected after 'module' (in [str_item])
Why can't I define modules anymore? How do I do to build maps on integers (Map.Make(OrdInt))?
The attached patch fixes a minor issue in two help descriptions.

I have adapted HOL Light
to compile natively. Now one is no longer restricted to a particular version of OCaml!
However it is just a start. For details see the holnat project.
Any feedback welcome in this thread or over at the new repo.
What steps will reproduce the problem?
1. load ocaml and hol.ml as usual
2. loadt "Library/analysis.ml";;
3. loadt "Multivariate/vectors.ml";;
What is the expected output? What do you see instead?
Expecting exit with no problems. Instead, it exits with the final lines:
val DOT_RMUL : thm = |- !c x y. x dot c % y = c * (x dot y)
Warning: inventing type variables
Exception: Failure "GEN_TAC".
Error in included file
/home/ivan/Dropbox/ReadSterling/hol_light/Multivariate/vectors.ml
val it : unit = ()
What version of the product are you using? On what operating system?
2.20++ , Linux Mint
Please provide any additional information below.
It appears that the "--" defined in analysis.ml conflicts somehow with the "--"
defined in realax.ml , or I may be completely off.

What steps will reproduce the problem?
Execute these commands:
# needs "Examples/prog.ml";;
# install_parser ("correct",parse_program_assertion);;
# g `correct
T
var x;
x := 1
end
x > 0`;;
# e VC_TAC;;
What is the expected output? What do you see instead?
VC_TAC should generate verification conditions `1 > 0`, but it leaves the goal
unmodified.
What version of the product are you using? On what operating system?
HOL Light from SVN, revision 200; ocaml 4.01.0, Linux
Please provide any additional information below.
VC_TAC works as expected if I introduce a dummy variable:
# g `correct T var x, dummy; x := 1 end x > 0`;;

What is the best way to communicate questions and collaborations for HOL Light?
For example Coq has:
Does HOL Light have something like this?
Or just stackoverflow?
Line 734 in 7381e2e
This line should be [VC_UNPACK_TAC; VC_UNPACK_TAC; GEN_TAC];(same as 728)
When matching a pattern which already contains MEASURE, GEN_TAC should be used instead.
Example:
`correct
T
var m,n;
do [invariant 0<=m ; measure m]
(if 0<n then n:=0;
m:= PRE m)
while 0<m
end
n=0`;;
With e VC_TAC, it outputs:
`m' = m /\ n' = n /\ ~(0 < n)
==> 0 <= PRE m /\ MEASURE (\(m,n). m) (PRE m,n) (m',n')`
`m' = m /\ n' = n /\ 0 < n
==> 0 <= PRE m /\ MEASURE (\(m,n). m) (PRE m,0) (m',n')`
`~(0 < m) /\ 0 <= m ==> n = 0`
`WF (MEASURE (\(m,n). m))`
This is because the match to correct p (ADO i (MEASURE m) c e) q
failed, correct p (ADO i v c e) q
was used instead,
With e (MATCH_MP_TAC VC_ADO_MEASURE THEN REPEAT CONJ_TAC THENL [VC_UNPACK_TAC; VC_UNPACK_TAC; GEN_TAC]), the output is:
`correct ((\(m,n). T) AND (\s. X = (\(m,n). m) s))
(IF (\(m,n). 0 < n) (Assign (\(m,n). m,0)) Seq Assign (\(m,n). PRE m,n))
((\(m,n). 0 <= m) AND (\s. (\(m,n). m) s < X))`
`~(0 < m) /\ 0 <= m ==> n = 0`
Where no MEASURE is found, and continue with VC_TAC, all VC goals will be generated normally
The README links to the ckpt
program at http://www.cs.wisc.edu/~zandy/ckpt. Unfortunately, that's a broken link. Does it have a new webpage elsewhere?
When I input " 'x+1' " in hol-light system , it responses "Illegal begin of top_parse", whats wrong with it ?, Thanks.
