To build, type make.

If it doesn't work, you probably aren't using godi.  You'll have to
edit the make file to tell it where your compiler sources are, as well
as possibly rewrite the very simple build rule to not use findlib.

A short description of features,

cmigrep: <args> <module-expr> 

cmigrep has two modes, the first and most common is that of searching
for various types of objects inside a module. Objects that you can
search for include

switch         purpose
-t             (regexp) print types with matching names
-r             (regexp) print record field labels with matching names
-c             (regexp) print constructors with matching names
-p             (regexp) print polymorphic variants with matching names
-e             (regexp) print exceptions with matching constructors
-v             (regexp) print values with matching names
-o             (regexp) print all classes with matching names
-a             (regexp) print all names which match the given expression

These are all very useful for finding specific things inside a given
module. Here are a few examples,

find some constructors in the unix module

itsg106:~ eric$ cmigrep -c SO_ Unix 
SO_DEBUG (* socket_bool_option *)
SO_BROADCAST (* socket_bool_option *)
SO_REUSEADDR (* socket_bool_option *)
SO_KEEPALIVE (* socket_bool_option *)
SO_DONTROUTE (* socket_bool_option *)
SO_OOBINLINE (* socket_bool_option *)
SO_ACCEPTCONN (* socket_bool_option *)
SO_SNDBUF (* socket_int_option *)
SO_RCVBUF (* socket_int_option *)
SO_ERROR (* socket_int_option *)
SO_TYPE (* socket_int_option *)
SO_RCVLOWAT (* socket_int_option *)
SO_SNDLOWAT (* socket_int_option *)
SO_LINGER (* socket_optint_option *)
SO_RCVTIMEO (* socket_float_option *)
SO_SNDTIMEO (* socket_float_option *)

find the same constructors, but this time anywhere

SO_DEBUG (* Unix.socket_bool_option *)

SO_REUSEADDR (* Unix.socket_bool_option *)
SO_KEEPALIVE (* Unix.socket_bool_option *)
SO_DONTROUTE (* Unix.socket_bool_option *)
SO_OOBINLINE (* Unix.socket_bool_option *)
SO_ACCEPTCONN (* Unix.socket_bool_option *)
SO_SNDBUF (* Unix.socket_int_option *)
SO_RCVBUF (* Unix.socket_int_option *)
SO_ERROR (* Unix.socket_int_option *)
SO_TYPE (* Unix.socket_int_option *)
SO_RCVLOWAT (* Unix.socket_int_option *)
SO_SNDLOWAT (* Unix.socket_int_option *)
SO_LINGER (* Unix.socket_optint_option *)
SO_RCVTIMEO (* Unix.socket_float_option *)
SO_SNDTIMEO (* Unix.socket_float_option *)

It seems they only exist in the unix module. By default cmigrep
searches the current directory, and the standard library. You can of
course tell it to search elsewhere.

full types get printed in the case that the constructors have
arguments. Notice that adding to the include path is modeled after the
compiler. Findlib is also supported.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
