These separate the different tasks it can perform. Almost all flag names are backwards compatible. The key tasks have not been ported to subcommands since they will be replaced by the new accounts infrastructure very soon. --- Godeps/Godeps.json | 5 + .../src/github.com/codegangsta/cli/.travis.yml | 6 + .../src/github.com/codegangsta/cli/LICENSE | 21 + .../src/github.com/codegangsta/cli/README.md | 298 +++++++++ .../src/github.com/codegangsta/cli/app.go | 296 ++++++++ .../src/github.com/codegangsta/cli/app_test.go | 619 +++++++++++++++++ .../codegangsta/cli/autocomplete/bash_autocomplete | 13 + .../codegangsta/cli/autocomplete/zsh_autocomplete | 5 + .../src/github.com/codegangsta/cli/cli.go | 19 + .../src/github.com/codegangsta/cli/cli_test.go | 100 +++ .../src/github.com/codegangsta/cli/command.go | 160 +++++ .../src/github.com/codegangsta/cli/command_test.go | 49 ++ .../src/github.com/codegangsta/cli/context.go | 339 ++++++++++ .../src/github.com/codegangsta/cli/context_test.go | 99 +++ .../src/github.com/codegangsta/cli/flag.go | 454 +++++++++++++ .../src/github.com/codegangsta/cli/flag_test.go | 742 +++++++++++++++++++++ .../src/github.com/codegangsta/cli/help.go | 211 ++++++ .../src/github.com/codegangsta/cli/helpers_test.go | 19 + cmd/ethereum/cmd.go | 40 -- cmd/ethereum/flags.go | 168 ----- cmd/ethereum/js.go | 43 ++ cmd/ethereum/main.go | 238 ++++--- cmd/utils/cmd.go | 25 +- cmd/utils/flags.go | 178 +++++ 24 files changed, 3840 insertions(+), 307 deletions(-) create mode 100644 Godeps/_workspace/src/github.com/codegangsta/cli/.travis.yml create mode 100644 Godeps/_workspace/src/github.com/codegangsta/cli/LICENSE create mode 100644 Godeps/_workspace/src/github.com/codegangsta/cli/README.md create mode 100644 Godeps/_workspace/src/github.com/codegangsta/cli/app.go create mode 100644 Godeps/_workspace/src/github.com/codegangsta/cli/app_test.go create mode 100644 Godeps/_workspace/src/github.com/codegangsta/cli/autocomplete/bash_autocomplete create mode 100644 Godeps/_workspace/src/github.com/codegangsta/cli/autocomplete/zsh_autocomplete create mode 100644 Godeps/_workspace/src/github.com/codegangsta/cli/cli.go create mode 100644 Godeps/_workspace/src/github.com/codegangsta/cli/cli_test.go create mode 100644 Godeps/_workspace/src/github.com/codegangsta/cli/command.go create mode 100644 Godeps/_workspace/src/github.com/codegangsta/cli/command_test.go create mode 100644 Godeps/_workspace/src/github.com/codegangsta/cli/context.go create mode 100644 Godeps/_workspace/src/github.com/codegangsta/cli/context_test.go create mode 100644 Godeps/_workspace/src/github.com/codegangsta/cli/flag.go create mode 100644 Godeps/_workspace/src/github.com/codegangsta/cli/flag_test.go create mode 100644 Godeps/_workspace/src/github.com/codegangsta/cli/help.go create mode 100644 Godeps/_workspace/src/github.com/codegangsta/cli/helpers_test.go delete mode 100644 cmd/ethereum/cmd.go delete mode 100644 cmd/ethereum/flags.go create mode 100644 cmd/ethereum/js.go create mode 100644 cmd/utils/flags.go diff --git a/Godeps/Godeps.json b/Godeps/Godeps.json index f0a3448c7..bf5b59c95 100644 --- a/Godeps/Godeps.json +++ b/Godeps/Godeps.json @@ -15,6 +15,11 @@ "Comment": "null-15", "Rev": "12e4b4183793ac4b061921e7980845e750679fd0" }, + { + "ImportPath": "github.com/codegangsta/cli", + "Comment": "1.2.0-74-g50c77ec", + "Rev": "50c77ecec0068c9aef9d90ae0fd0fdf410041da3" + }, { "ImportPath": "github.com/ethereum/ethash", "Comment": "v17-23-g2561e13", diff --git a/Godeps/_workspace/src/github.com/codegangsta/cli/.travis.yml b/Godeps/_workspace/src/github.com/codegangsta/cli/.travis.yml new file mode 100644 index 000000000..baf46abc6 --- /dev/null +++ b/Godeps/_workspace/src/github.com/codegangsta/cli/.travis.yml @@ -0,0 +1,6 @@ +language: go +go: 1.1 + +script: +- go vet ./... +- go test -v ./... diff --git a/Godeps/_workspace/src/github.com/codegangsta/cli/LICENSE b/Godeps/_workspace/src/github.com/codegangsta/cli/LICENSE new file mode 100644 index 000000000..5515ccfb7 --- /dev/null +++ b/Godeps/_workspace/src/github.com/codegangsta/cli/LICENSE @@ -0,0 +1,21 @@ +Copyright (C) 2013 Jeremy Saenz +All Rights Reserved. + +MIT LICENSE + +Permission is hereby granted, free of charge, to any person obtaining a copy of +this software and associated documentation files (the "Software"), to deal in +the Software without restriction, including without limitation the rights to +use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of +the Software, and to permit persons to whom the Software is furnished to do so, +subject to the following conditions: + +The above copyright notice and this permission notice shall be included in all +copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS +FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

The goal is to enable developers to write fast and distributable command line applications in an expressive way. + +You can view the API docs here: +http://godoc.org/github.com/codegangsta/cli + +## Overview +Command line apps are usually so tiny that there is absolutely no reason why your code should *not* be self-documenting. Things like generating help text and parsing command flags/options should not hinder productivity when writing a command line app. + +**This is where cli.go comes into play.** cli.go makes command line programming fun, organized, and expressive! + +## Installation +Make sure you have a working Go environment (go 1.1 is *required*). [See the install instructions](http://golang.org/doc/install.html). + +To install `cli.go`, simply run: +``` +$ go get github.com/codegangsta/cli +``` + +Make sure your `PATH` includes to the `$GOPATH/bin` directory so your commands can be easily used: +``` +export PATH=$PATH:$GOPATH/bin +``` + +## Getting Started +One of the philosophies behind cli.go is that an API should be playful and full of discovery. So a cli.go app can be as little as one line of code in `main()`. + +``` go +package main + +import ( + "os" + "github.com/codegangsta/cli" +) + +func main() { + cli.NewApp().Run(os.Args) +} +``` + +This app will run and show help text, but is not very useful. Let's give an action to execute and some help documentation: + +``` go +package main + +import ( + "os" + "github.com/codegangsta/cli" +) + +func main() { + app := cli.NewApp() + app.Name = "boom" + app.Usage = "make an explosive entrance" + app.Action = func(c *cli.Context) { + println("boom! I say!") + } + + app.Run(os.Args) +} +``` + +Running this already gives you a ton of functionality, plus support for things like subcommands and flags, which are covered below. + +## Example + +Being a programmer can be a lonely job. Thankfully by the power of automation that is not the case! Let's create a greeter app to fend off our demons of loneliness! + +Start by creating a directory named `greet`, and within it, add a file, `greet.go` with the following code in it: + +``` go +package main + +import ( + "os" + "github.com/codegangsta/cli" +) + +func main() { + app := cli.NewApp() + app.Name = "greet" + app.Usage = "fight the loneliness!" + app.Action = func(c *cli.Context) { + println("Hello friend!") + } + + app.Run(os.Args) +} +``` + +Install our command to the `$GOPATH/bin` directory: + +``` +$ go install +``` + +Finally run our new command: + +``` +$ greet +Hello friend! +``` + +cli.go also generates some bitchass help text: +``` +$ greet help +NAME: + greet - fight the loneliness! + +USAGE: + greet [global options] command [command options] [arguments...] + +VERSION: + 0.0.0 + +COMMANDS: + help, h Shows a list of commands or help for one command + +GLOBAL OPTIONS + --version Shows version information +``` + +### Arguments +You can lookup arguments by calling the `Args` function on `cli.Context`. + +``` go +... +app.Action = func(c *cli.Context) { + println("Hello", c.Args()[0]) +} +... +``` + +### Flags +Setting and querying flags is simple. +``` go +... +app.Flags = []cli.Flag { + cli.StringFlag{ + Name: "lang", + Value: "english", + Usage: "language for the greeting", + }, +} +app.Action = func(c *cli.Context) { + name := "someone" + if len(c.Args()) > 0 { + name = c.Args()[0] + } + if c.String("lang") == "spanish" { + println("Hola", name) + } else { + println("Hello", name) + } +} +... +``` + +#### Alternate Names + +You can set alternate (or short) names for flags by providing a comma-delimited list for the `Name`. e.g. + +``` go +app.Flags = []cli.Flag { + cli.StringFlag{ + Name: "lang, l", + Value: "english", + Usage: "language for the greeting", + }, +} +``` + +That flag can then be set with `--lang spanish` or `-l spanish`. Note that giving two different forms of the same flag in the same command invocation is an error. + +#### Values from the Environment + +You can also have the default value set from the environment via `EnvVar`. e.g. + +``` go +app.Flags = []cli.Flag { + cli.StringFlag{ + Name: "lang, l", + Value: "english", + Usage: "language for the greeting", + EnvVar: "APP_LANG", + }, +} +``` + +The `EnvVar` may also be given as a comma-delimited "cascade", where the first environment variable that resolves is used as the default. + +``` go +app.Flags = []cli.Flag { + cli.StringFlag{ + Name: "lang, l", + Value: "english", + Usage: "language for the greeting", + EnvVar: "LEGACY_COMPAT_LANG,APP_LANG,LANG", + }, +} +``` + +### Subcommands + +Subcommands can be defined for a more git-like command line app. +```go +... +app.Commands = []cli.Command{ + { + Name: "add", + ShortName: "a", + Usage: "add a task to the list", + Action: func(c *cli.Context) { + println("added task: ", c.Args().First()) + }, + }, + { + Name: "complete", + ShortName: "c", + Usage: "complete a task on the list", + Action: func(c *cli.Context) { + println("completed task: ", c.Args().First()) + }, + }, + { + Name: "template", + ShortName: "r", + Usage: "options for task templates", + Subcommands: []cli.Command{ + { + Name: "add", + Usage: "add a new template", + Action: func(c *cli.Context) { + println("new task template: ", c.Args().First()) + }, + }, + { + Name: "remove", + Usage: "remove an existing template", + Action: func(c *cli.Context) { + println("removed task template: ", c.Args().First()) + }, + }, + }, + }, +} +... +``` + +### Bash Completion + +You can enable completion commands by setting the `EnableBashCompletion` +flag on the `App` object. By default, this setting will only auto-complete to +show an app's subcommands, but you can write your own completion methods for +the App or its subcommands. +```go +... +var tasks = []string{"cook", "clean", "laundry", "eat", "sleep", "code"} +app := cli.NewApp() +app.EnableBashCompletion = true +app.Commands = []cli.Command{ + { + Name: "complete", + ShortName: "c", + Usage: "complete a task on the list", + Action: func(c *cli.Context) { + println("completed task: ", c.Args().First()) + }, + BashComplete: func(c *cli.Context) { + // This will complete if no args are passed + if len(c.Args()) > 0 { + return + } + for _, t := range tasks { + fmt.Println(t) + } + }, + } +} +... +``` + +#### To Enable + +Source the `autocomplete/bash_autocomplete` file in your `.bashrc` file while +setting the `PROG` variable to the name of your program: + +`PROG=myprogram source /.../cli/autocomplete/bash_autocomplete` + + +## Contribution Guidelines +Feel free to put up a pull request to fix a bug or maybe add a feature. I will give it a code review and make sure that it does not break backwards compatibility.

As a collaborator you are given the ability to merge others pull requests. It is very important that new code does not break existing code, so be careful about what code you do choose to merge. If you have any questions feel free to link @codegangsta to the issue in question and we can review it together. + +If you feel like you have contributed to the project but have not yet been added as a collaborator, I probably forgot to add you.

If DEFAULT_MSG is given +# as second argument, then the function will generate itself useful +# success and error messages. You can also supply a custom error +# message for the failure case.

It is recommended +# to use the original case version. If the FOUND_VAR option is not +# used, the default is _FOUND. +# +# As in the simple mode, if through are all valid, +# _FOUND will be set to TRUE. After REQUIRED_VARS the +# variables which are required for this package are listed. Following +# VERSION_VAR the name of the variable can be specified which holds the +# version of the package which has been found. If this is done, this +# version will be checked against the (potentially) specified required +# version used in the find_package() call. The EXACT keyword is also +# handled. The default messages include information about the required +# version and the version which has been actually found, both if the +# version is ok or not. If the package supports components, use the +# HANDLE_COMPONENTS option to enable handling them. In this case, +# find_package_handle_standard_args() will report which components have +# been found and which are missing, and the _FOUND variable +# will be set to FALSE if any of the required components (i.e. not the +# ones listed after OPTIONAL_COMPONENTS) are missing. Use the option +# CONFIG_MODE if your FindXXX.cmake module is a wrapper for a +# find_package(... NO_MODULE) call. In this case VERSION_VAR will be +# set to _VERSION and the macro will automatically check whether +# the Config module was found. Via FAIL_MESSAGE a custom failure +# message can be specified, if this is not used, the default message +# will be displayed. +# +# Example for mode 1: +# +# :: +# +# find_package_handle_standard_args(LibXml2 DEFAULT_MSG +# LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR) +# +# +# +# LibXml2 is considered to be found, if both LIBXML2_LIBRARY and +# LIBXML2_INCLUDE_DIR are valid.

If it is +# found, success will be reported, including the content of . On +# repeated Cmake runs, the same message won't be printed again. +# +# Example for mode 2: +# +# :: +# +# find_package_handle_standard_args(LibXslt +# FOUND_VAR LibXslt_FOUND +# REQUIRED_VARS LibXslt_LIBRARIES LibXslt_INCLUDE_DIRS +# VERSION_VAR LibXslt_VERSION_STRING) +# +# In this case, LibXslt is considered to be found if the variable(s) +# listed after REQUIRED_VAR are all valid, i.e. LibXslt_LIBRARIES and +# LibXslt_INCLUDE_DIRS in this case. The result will then be stored in +# LibXslt_FOUND . Also the version of LibXslt will be checked by using +# the version contained in LibXslt_VERSION_STRING. Since no +# FAIL_MESSAGE is given, the default messages will be printed. +# +# Another example for mode 2: +# +# :: +# +# find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4) +# find_package_handle_standard_args(Automoc4 CONFIG_MODE) +# +# In this case, FindAutmoc4.cmake wraps a call to find_package(Automoc4 +# NO_MODULE) and adds an additional search directory for automoc4.

There is no additional + * requirement to include \em cl.h and to use either the C++ or original C + * bindings it is enough to simply include \em cl.hpp. + * + * The bindings themselves are lightweight and correspond closely to the + * underlying C API. Using the C++ bindings introduces no additional execution + * overhead. + * + * For detail documentation on the bindings see: + * + * The OpenCL C++ Wrapper API 1.2 (revision 09) + * http://www.khronos.org/registry/cl/specs/opencl-cplusplus-1.2.pdf + * + * \section example Example + * + * The following example shows a general use case for the C++ + * bindings, including support for the optional exception feature and + * also the supplied vector and string classes, see following sections for + * decriptions of these features. + * + * \code + * #define __CL_ENABLE_EXCEPTIONS + * + * #if defined(__APPLE__) || defined(__MACOSX) + * #include + * #else + * #include + * #endif + * #include + * #include + * #include + * + * const char * helloStr = "__kernel void " + * "hello(void) " + * "{ " + * " " + * "} "; + * + * int + * main(void) + * { + * cl_int err = CL_SUCCESS; + * try { + * + * std::vector platforms; + * cl::Platform::get(&platforms); + * if (platforms.size() == 0) { + * std::cout << "Platform size 0\n"; + * return -1; + * } + * + * cl_context_properties properties[] = + * { CL_CONTEXT_PLATFORM, (cl_context_properties)(platforms[0])(), 0}; + * cl::Context context(CL_DEVICE_TYPE_CPU, properties); + * + * std::vector devices = context.getInfo(); + * + * cl::Program::Sources source(1, + * std::make_pair(helloStr,strlen(helloStr))); + * cl::Program program_ = cl::Program(context, source); + * program_.build(devices); + * + * cl::Kernel kernel(program_, "hello", &err); + * + * cl::Event event; + * cl::CommandQueue queue(context, devices[0], 0, &err); + * queue.enqueueNDRangeKernel( + * kernel, + * cl::NullRange, + * cl::NDRange(4,4), + * cl::NullRange, + * NULL, + * &event); + * + * event.wait(); + * } + * catch (cl::Error err) { + * std::cerr + * << "ERROR: " + * << err.what() + * << "(" + * << err.err() + * << ")" + * << std::endl; + * } + * + * return EXIT_SUCCESS; + * } + * + * \endcode + * + */ +#ifndef CL_HPP_ +#define CL_HPP_ + +#ifdef _WIN32 + +#include +#include +#include +#include + +#if defined(__CL_ENABLE_EXCEPTIONS) +#include +#endif // #if defined(__CL_ENABLE_EXCEPTIONS) + +#pragma push_macro("max") +#undef max +#if defined(USE_DX_INTEROP) +#include +#include +#endif +#endif // _WIN32 + +// +#if defined(USE_CL_DEVICE_FISSION) +#include +#endif + +#if defined(__APPLE__) || defined(__MACOSX) +#include +#include +#include +#else +#include +#include +#endif // !__APPLE__ + +// To avoid accidentally taking ownership of core OpenCL types +// such as cl_kernel constructors are made explicit +// under OpenCL 1.2 +#if defined(CL_VERSION_1_2) && !defined(CL_USE_DEPRECATED_OPENCL_1_1_APIS) +#define __CL_EXPLICIT_CONSTRUCTORS explicit +#else // #if defined(CL_USE_DEPRECATED_OPENCL_1_1_APIS) +#define __CL_EXPLICIT_CONSTRUCTORS +#endif // #if defined(CL_USE_DEPRECATED_OPENCL_1_1_APIS) + +// Define deprecated prefixes and suffixes to ensure compilation +// in case they are not pre-defined +#if !defined(CL_EXT_PREFIX__VERSION_1_1_DEPRECATED) +#define CL_EXT_PREFIX__VERSION_1_1_DEPRECATED +#endif // #if !defined(CL_EXT_PREFIX__VERSION_1_1_DEPRECATED) +#if !defined(CL_EXT_SUFFIX__VERSION_1_1_DEPRECATED) +#define CL_EXT_SUFFIX__VERSION_1_1_DEPRECATED +#endif // #if !defined(CL_EXT_PREFIX__VERSION_1_1_DEPRECATED) + +#if !defined(CL_CALLBACK) +#define CL_CALLBACK +#endif //CL_CALLBACK + +#include +#include + +#if !defined(__NO_STD_VECTOR) +#include +#endif + +#if !defined(__NO_STD_STRING) +#include +#endif + +#if defined(linux) || defined(__APPLE__) || defined(__MACOSX) +#include + +#include +#include +#endif // linux + +#include + + +/*! \namespace cl + * + * \brief The OpenCL C++ bindings are defined within this namespace. + * + */ +namespace cl { + +class Memory; + +/** + * Deprecated APIs for 1.2 + */ +#if defined(CL_USE_DEPRECATED_OPENCL_1_1_APIS) || (defined(CL_VERSION_1_1) && !defined(CL_VERSION_1_2)) +#define __INIT_CL_EXT_FCN_PTR(name) \ + if(!pfn_##name) { \ + pfn_##name = (PFN_##name) \ + clGetExtensionFunctionAddress(#name); \ + if(!pfn_##name) { \ + } \ + } +#endif // #if defined(CL_VERSION_1_1) + +#if defined(CL_VERSION_1_2) +#define __INIT_CL_EXT_FCN_PTR_PLATFORM(platform, name) \ + if(!pfn_##name) { \ + pfn_##name = (PFN_##name) \ + clGetExtensionFunctionAddressForPlatform(platform, #name); \ + if(!pfn_##name) { \ + } \ + } +#endif // #if defined(CL_VERSION_1_1) + +class Program; +class Device; +class Context; +class CommandQueue; +class Memory; +class Buffer; + +#if defined(__CL_ENABLE_EXCEPTIONS) +/*! \brief Exception class + * + * This may be thrown by API functions when __CL_ENABLE_EXCEPTIONS is defined. + */ +class Error : public std::exception +{ +private: + cl_int err_; + const char * errStr_; +public: + /*! \brief Create a new CL error exception for a given error code + * and corresponding message. + * + * \param err error code value. + * + * \param errStr a descriptive string that must remain in scope until + * handling of the exception has concluded.
