ppx-base1

Overview

ppx-base [extra_args] [<files>]

-as-ppx

Run as a -ppx rewriter (must be the first argument)

--as-ppx

Same as -as-ppx

-as-pp

Shorthand for: -dump-ast -embed-errors

--as-pp

Same as -as-pp

-o <filename>

Output file (use '-' for stdout)

-

Read input from stdin

-dump-ast

Dump the marshaled ast to the output file instead of pretty-printing it

--dump-ast

Same as -dump-ast

-dparsetree

Print the parsetree (same as ocamlc -dparsetree)

-embed-errors

Embed errors in the output AST (default: true when -as-pp, false otherwise)

-null

Produce no output, except for errors

-impl <file>

Treat the input as a .ml file

--impl <file>

Same as -impl

-intf <file>

Treat the input as a .mli file

--intf <file>

Same as -intf

-debug-attribute-drop

Debug attribute dropping

-print-transformations

Print linked-in code transformations, in the order they are applied

-print-passes

Print the actual passes over the whole AST in the order they are applied

-ite-check

(no effect -- kept for compatibility)

-pp <command>

Pipe sources through preprocessor <command> (incompatible with -as-ppx)

-reconcile

(WIP) Pretty print the output using a mix of the input source and the generated code

-reconcile-with-comments

(WIP) same as -reconcile but uses comments to enclose the generated code

-no-color

Don't use colors when printing errors

-diff-cmd

Diff command when using code expectations (use - to disable diffing)

-pretty

Instruct code generators to improve the prettiness of the generated code

-styler

Code styler

-output-metadata FILE

Where to store the output metadata

-corrected-suffix SUFFIX

Suffix to append to corrected files

-keywords <version+list>

Set keywords according to the version+list specification. Allows using a set of keywords different from the one of the current compiler for backward compatibility.

--keywords <version+list>

Same as -keywords

--use-compiler-pp Force

migrating the AST back to the compiler's version before printing it as source code using the compiler's Pprintast utilities.

-loc-filename <string>

File name to use in locations

-reserve-namespace <string>

Mark the given namespace as reserved

-no-check

Disable checks (unsafe)

-check

Enable checks

-no-check-on-extensions

Disable checks on extension point only

-check-on-extensions

Enable checks on extension point only

-no-locations-check

Disable locations check only

-locations-check

Enable locations check only

-apply <names>

Apply these transformations in order (comma-separated list)

-dont-apply <names>

Exclude these transformations

-no-merge

Do not merge context free transformations (better for debugging rewriters). As a result, the context-free transformations are not all applied before all impl and intf.

-cookie NAME=EXPR

Set the cookie NAME to EXPR

--cookie

Same as -cookie

-deriving-keep-w32 {impl|intf|both}

Do not try to disable warning 32 for the generated code

-deriving-disable-w32-method {code|attribute}

How to disable warning 32 for the generated code

-type-conv-keep-w32 {impl|intf|both}

Deprecated, use -deriving-keep-w32

-type-conv-w32 {code|attribute}

Deprecated, use -deriving-disable-w32-method

-deriving-keep-w60 {impl|intf|both}

Do not try to disable warning 60 for the generated code

-unused-code-warnings {true|false|force}

Allow ppx derivers to enable unused code warnings (default: false)

-unused-type-warnings {true|false|force}

Allow unused type warnings for types with [@@deriving ...] (default: false)
