Console

ArcanistGridCellClassArcanistGridColumnClassArcanistGridRowClassArcanistGridViewClassphutil_console_confirm()Functionphutil_console_format()Functionphutil_console_get_terminal_width()FunctionDetermine the width of the terminal, if possible. Returns `null` on failure.phutil_console_prompt()Functionphutil_console_require_tty()Functionphutil_console_select()Functionphutil_console_wrap()FunctionSoft wrap text for display on a console, respecting UTF8 character boundaries and ANSI color escape sequences.PhutilConsoleClassProvides access to the command-line console. Instead of reading from or writing to stdin/stdout/stderr directly, this class provides a richer API including support for ANSI color and formatting, convenience methods for prompting the user, and the ability to interact with stdin/stdout/stderr in some other process instead of this one.PhutilConsoleBlockClassPhutilConsoleErrorClassPhutilConsoleFormatterClassPhutilConsoleInfoClassPhutilConsoleListClassPhutilConsoleLogLineClassPhutilConsoleMessageClassPhutilConsoleMetricsClassPhutilConsoleProgressBarClassShow a progress bar on the console. Usage:PhutilConsoleServerClassPhutilConsoleServerChannelClassPhutilConsoleSkipClassPhutilConsoleStdinNotInteractiveExceptionClassThrown when you prompt the user with @{function:phutil_console_prompt} or @{function:phutil_console_confirm} but stdin is not an interactive TTY so the user can't possibly respond. Usually this means the user ran the command with something piped into stdin.PhutilConsoleTableClassShow a table in the console. Usage:PhutilConsoleViewClassPhutilConsoleWarningClassPhutilConsoleWrapTestCaseClassPhutilInteractiveEditorClassEdit a document interactively, by launching $EDITOR (like vi or nano).

Errors

phlog()Functionlibphutil log function for development debugging. Takes any argument and forwards it to registered listeners. This is essentially a more powerful version of `error_log()`.phutil_error_listener_example()FunctionExample @{class:PhutilErrorHandler} error listener callback. When you call `PhutilErrorHandler::setErrorListener()`, you must pass a callback function with the same signature as this one.PhutilAggregateExceptionClassException that aggregates other exceptions into a single exception. For example, if you have several objects which can perform a task and just want at least one of them to succeed, you can do something like this:PhutilErrorHandlerClassImprove PHP error logs and optionally route errors, exceptions and debugging information to a central listener.PhutilErrorHandlerTestCaseClassPhutilErrorTrapClassTrap PHP errors while this object is alive, so they can be accessed and included in exceptions or other types of logging. For example, if you have code like this:PhutilMethodNotImplementedExceptionClassAn exception thrown when a method is called on a class which does not provide an implementation for the called method. This is sometimes the case when a base class expects subclasses to provide their own implementations, for example.PhutilOpaqueEnvelopeClassOpaque reference to a string (like a password) that won't put any sensitive data in stack traces, var_dump(), print_r(), error logs, etc. Usage:PhutilOpaqueEnvelopeKeyClassHolds the key for @{class:PhutilOpaqueEnvelope} in a logically distant location so it will never appear in stack traces, etc. You should never need to use this class directly. See @{class:PhutilOpaqueEnvelope} for information about opaque envelopes.PhutilOpaqueEnvelopeTestCaseClassPhutilProxyExceptionClassPrior to PHP 5.3, PHP does not support nested exceptions; this class provides limited support for nested exceptions. Use methods on @{class:PhutilErrorHandler} to unnest exceptions in a forward-compatible way.

Filesystem

ArcanistHostMemorySnapshotClassArcanistHostMemorySnapshotTestCaseClassFileFinderClassFind files on disk matching criteria, like the 'find' system utility. Use of this class is straightforward:FileFinderTestCaseClassFileListClassA list of files, primarily useful for parsing command line arguments. This class makes it easier to deal with user-specified lists of files and directories used by command line tools.FilesystemClassSimple wrapper class for common filesystem tasks like reading and writing files. When things go wrong, this class throws detailed exceptions with good information about what didn't work.FilesystemExceptionClassException thrown by Filesystem to indicate an error accessing the file system.FilesystemTestCaseClassLinesOfALargeClassAbstraction for processing large inputs without holding them in memory. This class implements line-oriented, buffered reads of some external stream, where a "line" is characterized by some delimiter character. This provides a straightforward interface for most large-input tasks, with relatively good performance.LinesOfALargeExecFutureClassRead the output stream of an @{class:ExecFuture} one line at a time. This abstraction allows you to process large inputs without holding them in memory. If you know your inputs fit in memory, it is generally more efficient (and certainly simpler) to read the entire input and `explode()` it. For more information, see @{class:LinesOfALarge}. See also @{class:LinesOfALargeFile} for a similar abstraction that works on files.LinesOfALargeExecFutureTestCaseClassLinesOfALargeFileClassRead the lines of a file, one at a time. This allows you to process large files without holding them in memory. In most cases, it is more efficient (and certainly simpler) to read the entire file and `explode()` it. For more information, see @{class:LinesOfALarge}. See also @{class:LinesOfALargeExecFuture}, for a similar abstraction that works on executed commands.LinesOfALargeFileTestCaseClassPhutilBinaryAnalyzerClassPhutilBinaryAnalyzerTestCaseClassPhutilDeferredLogClassObject that writes to a logfile when it is destroyed. This allows you to add more data to the log as execution unfolds, while still ensuring a write in normal circumstances (see below for discussion of cases where writes may not occur).PhutilDeferredLogTestCaseClassPhutilDiffBinaryAnalyzerClassPhutilDirectoryFixtureClassPhutilErrorLogClassPhutilFileLockClassWrapper around `flock()` for advisory filesystem locking. Usage is straightforward:PhutilFileLockTestCaseClassPhutilGitBinaryAnalyzerClassPhutilLockClassBase class for locks, like file locks.PhutilLockExceptionClassPhutilMercurialBinaryAnalyzerClassPhutilProcessQueryClassPhutilProcessRefClassPhutilProcessRefTestCaseClassPhutilPygmentizeBinaryAnalyzerClassPhutilSubversionBinaryAnalyzerClassTempFileClassSimple wrapper to create a temporary file and guarantee it will be deleted on object destruction. Used like a string to path:

Futures

Using FuturesArticleOverview of how futures work in libphutil.BaseHTTPFutureClassExecute HTTP requests with a future-oriented API. For example:CommandExceptionClassException thrown when a system command fails.exec_manual()FunctionExecute a command and capture stdout, stderr, and the return value.ExecFutureClassExecute system commands in parallel using futures.ExecFutureTestCaseClassExecPassthruTestCaseClassexecx()FunctionExecute a command and capture stdout and stderr. If the command exits with a nonzero error code, a @{class:CommandException} will be thrown. If you need to manually handle error conditions, use @{function:exec_manual}.FutureClassA 'future' or 'promise' is an object which represents the result of some pending computation. For a more complete overview of futures, see @{article:Using Futures}.FutureIteratorClassFutureIterator aggregates @{class:Future}s and allows you to respond to them in the order they resolve. This is useful because it minimizes the amount of time your program spends waiting on parallel processes.FutureIteratorTestCaseClassFuturePoolClassFutureProxyClassWraps another @{class:Future} and allows you to post-process its result once it resolves.HTTPFutureClassSocket-based HTTP future, for making HTTP requests using future semantics. This is an alternative to @{class:CURLFuture} which has better resolution behavior (select()-based wait instead of busy wait) but fewer features. You should prefer this class to @{class:CURLFuture} unless you need its advanced features (like HTTP/1.1, chunked transfer encoding, gzip, etc.).HTTPFutureCertificateResponseStatusClassHTTPFutureCURLResponseStatusClassHTTPFutureHTTPResponseStatusClassHTTPFutureParseResponseStatusClassHTTPFutureResponseStatusClassHTTPFutureTransportResponseStatusClassHTTPSFutureClassVery basic HTTPS future.ImmediateFutureClassDegenerate future which returns an already-existing result without performing any computation.MethodCallFutureClassDegenerate future which resolves by calling a method.MethodCallFutureTestCaseClassphutil_get_signal_name()FunctionReturn a human-readable signal name (like "SIGINT" or "SIGKILL") for a given signal number.phutil_passthru()FunctionWrapper for @{class:PhutilExecPassthru}.PhutilAsanaFutureClassPhutilAWSCloudFormationFutureClassPhutilAWSCloudWatchFutureClassPhutilAWSEC2FutureClassPhutilAWSExceptionClassPhutilAWSFutureClassPhutilAWSManagementWorkflowClassPhutilAWSS3DeleteManagementWorkflowClassPhutilAWSS3FutureClassPhutilAWSS3GetManagementWorkflowClassPhutilAWSS3ManagementWorkflowClassPhutilAWSS3PutManagementWorkflowClassPhutilAWSv4SignatureClassPhutilAWSv4SignatureTestCaseClassPhutilBacktraceSignalHandlerClassSignal handler for SIGHUP which prints the current backtrace out to a file. This is particularly helpful in debugging hung/spinning processes.PhutilCallbackSignalHandlerClassPhutilCloudWatchMetricClassPhutilConsoleMetricsSignalHandlerClassPhutilExecPassthruClassExecute a command which takes over stdin, stdout and stderr, similar to `passthru()`, but which preserves TTY semantics, escapes arguments, and is traceable.PhutilExecutableFutureClassPhutilGitHubFutureClassPhutilGitHubResponseClassPhutilHTTPEngineExtensionClassExtend HTTP behavior by injecting proxies or compromising SSL.PhutilOAuth1FutureClassProxy future that implements OAuth1 request signing.

Internationalization

ArcanistUSEnglishTranslationClassLibphutilUSEnglishTranslationClasspht()FunctionTranslate a string. It uses a translator set by `PhutilTranslator::setInstance()` or translations specified by `PhutilTranslator::getInstance()->setTranslations()` and language rules set by `PhutilTranslator::getInstance()->setLocale()`.pht_list()Functionphutil_count()FunctionCount all elements in an array, or something in an object.phutil_person()FunctionProvide a gendered argument to the translation engine.PhutilAllCapsEnglishLocaleClassA test locale which transforms strings into uppercase.PhutilBritishEnglishLocaleClassSerious, legitimate British English locale.PhutilCzechLocaleClassLocale for "Czech (Czech Republic)".PhutilEmojiLocaleClassA picture is worth a thousand words.PhutilEnglishCanadaLocaleClassLocale for "English (Canada)".PhutilFrenchLocaleClassLocale for "French (France)".PhutilGermanLocaleClassLocale for "German (Germany)".PhutilKoreanLocaleClassThe Korean (Republic of Korea) LocalePhutilLocaleClassDefines a locale for translations.PhutilLocaleTestCaseClassPhutilNumberClassPhutilPersonInterfacePhutilPersonTestClassPhutilPhtTestCaseClassTest cases for functions in pht.php.PhutilPirateEnglishLocaleClassArrr!PhutilPortugueseBrazilLocaleClassLocale for "Portuguese (Brazil)".PhutilPortuguesePortugalLocaleClassLocale for "Portuguese (Portugal)".PhutilRawEnglishLocaleClassA test locale which displays the raw strings which are fed into the translation engine.PhutilSimplifiedChineseLocaleClassLocale for "Chinese (Simplified)".PhutilSpanishSpainLocaleClassThe Spanish (Spain) LocalePhutilTraditionalChineseLocaleClassLocale for "Chinese (Traditional)".PhutilTranslationClassPhutilTranslationTestCaseClassPhutilTranslatorClassPhutilTranslatorTestCaseClassPhutilUSEnglishLocaleClassThe default English locale.PhutilVeryWowEnglishLocaleClassMuch locale! Very English! Wow!

Parsers

AASTNodeClassAASTNodeListClassAASTTokenClassAASTTreeClassAn abstract abstract syntax tree.ArcanistBaseCommitParserClassArcanistBaseCommitParserTestCaseClassArcanistBundleClassConverts changesets between different formats.ArcanistBundleTestCaseClassArcanistCommentRemoverClassArcanistCommentRemoverTestCaseClassArcanistDiffChangeClassRepresents a change to an individual path.ArcanistDiffChangeTypeClassDefines constants for file types and operations in changesets.ArcanistDiffHunkClassRepresents a contiguous set of added and removed lines in a diff.ArcanistDiffParserClassParses diffs from a working copy.ArcanistDiffParserTestCaseClassTest cases for @{class:ArcanistDiffParser}.PHPASTParserTestCaseClassPhutilArgumentParserClassParser for command-line arguments for scripts. Like similar parsers, this class allows you to specify, validate, and render help for command-line arguments. For example:PhutilArgumentParserExceptionClassPhutilArgumentParserTestCaseClassPhutilArgumentSpecificationClassPhutilArgumentSpecificationExceptionClassPhutilArgumentSpecificationTestCaseClassPhutilArgumentSpellingCorrectorClassPhutilArgumentSpellingCorrectorTestCaseClassPhutilArgumentUsageExceptionClassPhutilArgumentWorkflowClassUsed with @{class:PhutilArgumentParser} to build command line tools which operate in several modes, called "workflows", like `git`, `svn`, `arc`, `apt-get`. For example, you might build a simple calculator like this:PhutilBugtraqParserClassReplaces ticket or issue IDs in a block of text with links. This mechanism is based on (and compatible with) the Bugtraq system in TortiseSVN. SeePhutilBugtraqParserTestCaseClassPhutilDocblockParserClassParse a docblock comment from source code into raw text documentation and metadata (like "@author" and "@return").PhutilDocblockParserTestCaseClassTest cases for @{class:PhutilDocblockParser}.PhutilDOMNodeClassPhutilEditorConfigClassParser for [[http://editorconfig.org/ | EditorConfig]] files.PhutilEditorConfigTestCaseClassPhutilEmailAddressClassBasic email address parser. This parser is very liberal and does not attempt to be fully RFC-compliant, because trying to do so is a crazy mess. However, it should parse all reasonable addresses which are actually in use on the internet today.PhutilEmailAddressTestCaseClassTest cases for @{class:PhutilEmailAddress} parser.PhutilGitURIClassParser for the alternate URI scheme used by SCP and Git, which look like this:PhutilGitURITestCaseClassPhutilHelpArgumentWorkflowClassPhutilHTMLParserClassPhutilHTMLParserTestCaseClassPhutilHTTPResponseClassPhutilHTTPResponseParserClassPhutilHTTPResponseParserTestCaseClassPhutilINIParserExceptionClassPhutilInvalidRuleParserGeneratorExceptionClassPhutilIrreducibleRuleParserGeneratorExceptionClassPhutilJSONClassUtilities for wrangling JSON.PhutilJSONParserClassA JSON parser.PhutilJSONParserExceptionClassPhutilJSONParserTestCaseClassPhutilJSONTestCaseClassPhutilLanguageGuesserClassVery simple class to guess the languages of source files which we failed to determine by examining file name/extension rules.PhutilLanguageGuesserTestCaseClassPhutilParserGeneratorClassSimple LR(1) parser generator. Generally, build a parser by setting terminals and rules, then calling @{method:processGrammar}. For example, here is a simple grammar which accepts one or more "a" followed by exactly one "b":PhutilParserGeneratorExceptionClassPhutilParserGeneratorTestCaseClassPhutilQueryStringParserClassUtilities for parsing HTTP query strings.PhutilQueryStringParserTestCaseClassTest cases for @{class:PhutilQueryStringParser} parser.PhutilSimpleOptionsClassUtilities for parsing simple option lists used in Remarkup, like codeblocks:PhutilSimpleOptionsTestCaseClassPhutilTypeCheckExceptionClassPhutilTypeExtraParametersExceptionClassPhutilTypeMissingParametersExceptionClassPhutilTypeSpecClassPerform type checks using a simple type grammar.

Core Utilities

Core Utilities Quick ReferenceArticleSummary of libphutil core utilities.AbstractDirectedGraphClassModels a directed graph in a generic way that works well with graphs stored in a database, and allows you to perform operations like cycle detection.AbstractDirectedGraphTestCaseClassArcanistNonblockingGuardClassarray_fuse()FunctionSimplifies a common use of `array_combine()`. Specifically, this:array_interleave()FunctionAdd an element between every two elements of some array. That is, given a list `A, B, C, D`, and some element to interleave, `x`, this function returns `A, x, B, x, C, x, D`. This works like `implode()`, but does not concatenate the list into a string. In particular:array_mergev()FunctionMerge a vector of arrays performantly. This has the same semantics as array_merge(), so these calls are equivalent:array_select_keys()FunctionSelects a list of keys from an array, returning a new array with only the key-value pairs identified by the selected keys, in the specified order.assert_instances_of()FunctionChecks if all values of array are instances of the passed class. Throws `InvalidArgumentException` if it isn't true for any value.assert_same_keys()FunctionAssert that two arrays have the exact same keys, in any order.assert_stringlike()FunctionAssert that passed data can be converted to string.CaseInsensitiveArrayClassA case-insensitive associative array.CaseInsensitiveArrayTestCaseClasscoalesce()FunctionReturns the first argument which is not strictly null, or `null` if there are no such arguments. Identical to the MySQL function of the same name.head()FunctionReturns the first element of an array. Exactly like reset(), but doesn't choke if you pass it some non-referenceable value like the return value of a function.head_key()FunctionReturns the first key of an array.id()FunctionIdentity function, returns its argument unmodified.idx()FunctionAccess an array index, retrieving the value stored there if it exists or a default if it does not. This function allows you to concisely access an index which may or may not exist without raising a warning.idxv()FunctionAccess a sequence of array indexes, retrieving a deeply nested value if it exists or a default if it does not.ifilter()FunctionFilter a list of arrays by removing the ones with an empty() value for some index. This function works just like @{function:mfilter}, except that it operates on a list of arrays instead of a list of objects.igroup()FunctionGroup a list of arrays by the value of some index. This function is the same as @{function:mgroup}, except it operates on the values of array indexes rather than the return values of method calls.ipull()FunctionChoose an index from a list of arrays. Short for "index pull", this function works just like @{function:mpull}, except that it operates on a list of arrays and selects an index from them instead of operating on a list of objects and calling a method on them.isort()FunctionSort a list of arrays by the value of some index. This method is identical to @{function:msort}, but operates on a list of arrays instead of a list of objects.last()FunctionReturns the last element of an array. This is exactly like `end()` except that it won't warn you if you pass some non-referencable array to it -- e.g., the result of some other array operation.last_key()FunctionReturns the last key of an array.mfilter()FunctionFilter a list of objects by executing a method across all the objects and filter out the ones with empty() results. this function works just like @{function:ifilter}, except that it operates on a list of objects instead of a list of arrays.MFilterTestHelperClassmgroup()FunctionGroup a list of objects by the result of some method, similar to how GROUP BY works in an SQL query. This function simplifies grouping objects by some property:mpull()FunctionCall a method on a list of objects. Short for "method pull", this function works just like @{function:ipull}, except that it operates on a list of objects instead of a list of arrays. This function simplifies a common type of mapping operation:msort()FunctionSort a list of objects by the return value of some method. In PHP, this is often vastly more efficient than `usort()` and similar.msortv()FunctionSort a list of objects by a sort vector.msortv_internal()Functionmsortv_natural()Functionnewv()FunctionInvokes the "new" operator with a vector of arguments. There is no way to `call_user_func_array()` on a class constructor, so you can instead use this function:nonempty()FunctionSimilar to @{function:coalesce}, but less strict: returns the first non-`empty()` argument, instead of the first argument that is strictly non-`null`. If no argument is nonempty, it returns the last argument. This is useful idiomatically for setting defaults:phutil_build_http_querystring()FunctionBuild a query string from a dictionary.phutil_build_http_querystring_from_pairs()FunctionBuild a query string from a list of parameter pairs.phutil_censor_credentials()FunctionAttempt to censor any plaintext credentials from a string.phutil_date_format()Functionphutil_decode_mime_header()Functionphutil_describe_type()FunctionReturn a short, human-readable description of an object's type.phutil_encode_log()Functionphutil_escape_uri()FunctionEscape text for inclusion in a URI or a query parameter. Note that this method does NOT escape '/', because "%2F" is invalid in paths and Apache will automatically 404 the page if it's present. This will produce correct (the URIs will work) and desirable (the URIs will be readable) behavior in these cases:phutil_escape_uri_path_component()FunctionEscape text for inclusion as an infix URI substring. See discussion at @{function:phutil_escape_uri}. This function covers an unusual special case; @{function:phutil_escape_uri} is usually the correct function to use.phutil_fnmatch()FunctionAn improved version of `fnmatch`.phutil_format_bytes()FunctionFormat a byte count for human consumption, e.g. "10MB" instead of "10485760".phutil_format_relative_time()Functionphutil_format_relative_time_detailed()FunctionFormat a relative time (duration) into weeks, days, hours, minutes, seconds, but unlike phabricator_format_relative_time, does so for more than just the largest unit.phutil_format_units_generic()Functionphutil_fwrite_nonblocking_stream()FunctionPerform an `fwrite()` which distinguishes between EAGAIN and EPIPE.phutil_get_system_locale()FunctionReturn the current system locale setting (LC_ALL).phutil_glue()FunctionInsert a value in between each pair of elements in a list.phutil_hashes_are_identical()FunctionCompare two hashes for equality.phutil_http_parameter_pair()FunctionTypecheck and cast an HTTP key-value parameter pair.phutil_ini_decode()FunctionDecode an INI string.phutil_is_hiphop_runtime()Functionphutil_is_interactive()Functionphutil_is_natural_list()FunctionTest if a list has the natural numbers (1, 2, 3, and so on) as keys, in order.phutil_is_noninteractive()Functionphutil_is_system_locale_available()FunctionTest if a system locale (LC_ALL) is available on the system.phutil_is_utf8()FunctionDetermine if a string is valid UTF-8.phutil_is_utf8_slowly()FunctionDetermine if a string is valid UTF-8, slowly.phutil_is_utf8_with_only_bmp_characters()FunctionDetermine if a string is valid UTF-8, with only basic multilingual plane characters. This is particularly important because MySQL's `utf8` column types silently truncate strings which contain characters outside of this set.phutil_is_windows()Functionphutil_json_decode()FunctionDecode a JSON dictionary.phutil_json_encode()FunctionEncode a value in JSON, raising an exception if it can not be encoded.phutil_loggable_string()FunctionConverts a string to a loggable one, with unprintables and newlines escaped.phutil_microseconds_since()FunctionCompute the number of microseconds that have elapsed since an earlier timestamp (from `microtime(true)`).phutil_nonempty_scalar()FunctionTest if a value is a nonempty, scalar value.phutil_nonempty_string()FunctionTest if a value is a nonempty string.phutil_nonempty_stringlike()FunctionTest if a value is a nonempty, stringlike value.phutil_parse_bytes()FunctionParse a human-readable byte description (like "6MB") into an integer.phutil_partition()Functionphutil_preg_match()Functionphutil_preg_match_all()Functionphutil_raise_preg_exception()Functionphutil_set_system_locale()FunctionSet the system locale (LC_ALL) to a particular value.phutil_split_lines()FunctionSplit a corpus of text into lines. This function splits on "\n", "\r\n", or a mixture of any of them.phutil_string_cast()FunctionPerform a "(string)" cast without disabling standard exception behavior.phutil_unescape_uri_path_component()FunctionUnescape text that was escaped by @{function:phutil_escape_uri_path_component}. See @{function:phutil_escape_uri} for discussion.phutil_units()FunctionConvert a human-readable unit description into a numeric one. This function allows you to replace this:phutil_utf8_console_strlen()FunctionFind the console display length of a UTF-8 string. This may differ from the character length of the string if it contains double-width characters, like many Chinese characters.phutil_utf8_convert()FunctionConvert a string from one encoding (like ISO-8859-1) to another encoding (like UTF-8).phutil_utf8_encode_codepoint()FunctionConvert a Unicode codepoint into a UTF8-encoded string.phutil_utf8_hard_wrap()FunctionHard-wrap a block of UTF-8 text with no embedded HTML tags and entities.phutil_utf8_hard_wrap_html()FunctionHard-wrap a block of UTF-8 text with embedded HTML tags and entities.phutil_utf8_is_cjk()FunctionTest if a string contains Chinese, Japanese, or Korean characters.phutil_utf8_is_combining_character()FunctionDetermine if a given unicode character is a combining character or not.phutil_utf8_strlen()FunctionFind the character length of a UTF-8 string.phutil_utf8_strtolower()FunctionConvert a string to lower case in a UTF8-aware way. Similar to @{function:strtolower}.phutil_utf8_strtoupper()FunctionConvert a string to upper case in a UTF8-aware way. Similar to @{function:strtoupper}.phutil_utf8_strtr()FunctionReplace characters in a string in a UTF-aware way. Similar to @{function:strtr}.phutil_utf8_ucwords()FunctionConvert a string to title case in a UTF8-aware way. This function doesn't necessarily do a great job, but the builtin implementation of `ucwords()` can completely destroy inputs, so it just has to be better than that. Similar to @{function:ucwords}.phutil_utf8ize()FunctionConvert a string into valid UTF-8. This function is quite slow.phutil_utf8v()FunctionSplit a UTF-8 string into an array of characters. Combining characters are also split.phutil_utf8v_codepoints()FunctionSplit a UTF-8 string into an array of codepoints (as integers).phutil_utf8v_combine_characters()FunctionMerge combining characters in a UTF-8 string.phutil_utf8v_combined()FunctionSplit a UTF-8 string into an array of characters. Combining characters are not split.phutil_validate_json()FunctionProduce a human-readable explanation why a value can not be JSON-encoded.phutil_var_export()FunctionReturns a parsable string representation of a variable.PhutilArrayClassAbstract base class for implementing objects that behave like arrays. This class wraps a basic array and provides trivial implementations for `Countable`, `ArrayAccess` and `Iterator`, so subclasses need only implement specializations.PhutilArrayCheckClassPhutilArrayTestCaseClassTest cases for @{class:PhutilArray} subclasses.PhutilArrayWithDefaultValueClassArray-like object with a default value that is populated when nonexistent keys are accessed. This is particularly useful to avoid constructs like this:PhutilBufferedIteratorClassSimple iterator that loads results page-by-page and handles buffering. In particular, this maps well to iterators that load database results page by page and allows you to implement an iterator over a large result set without needing to hold the entire set in memory.PhutilBufferedIteratorTestCaseClassTest cases for @{class:PhutilExampleBufferedIterator}.PhutilCallbackFilterIteratorClassNOTE: This class has the same purpose as `CallbackFilterIterator` in PHP 5.4.PhutilChunkedIteratorClassThis is an iterator version of `array_chunk()`.PhutilChunkedIteratorTestCaseClassTest cases for @{class:PhutilChunkedIterator}.PhutilCowsayClassParser and renderer for ".cow" files used by the `cowsay` program.PhutilCowsayTestCaseClassPhutilDirectedScalarGraphClassConcrete subclass of @{class:AbstractDirectedGraph} which can not load any data from external sources.PhutilEditDistanceMatrixClassCompute edit distance between two scalar sequences. This class uses Levenshtein (or Damerau-Levenshtein) to compute the edit distance between two inputs. The inputs are arrays containing any scalars (not just strings) so it can be used with, e.g., utf8 sequences.PhutilEditDistanceMatrixTestCaseClassPhutilExampleBufferedIteratorClassExample implementation and test case for @{class:PhutilBufferedIterator}.PhutilExecutionEnvironmentClassGet information about the current execution environment.PhutilHashingIteratorClassPhutilHashingIteratorTestCaseClassPhutilLunarPhaseClassCompute the phase of the terran moon for a given epoch.PhutilLunarPhaseTestCaseClassPhutilProxyIteratorClassPhutilRopeClassString-like object which reduces the cost of managing large strings. This is particularly useful for buffering large amounts of data that is being passed to `fwrite()`.PhutilRopeTestCaseClassPhutilSortVectorClassPhutilStreamIteratorClassPhutilSystemClassInteract with the operating system.PhutilSystemTestCaseClassPhutilUTF8StringTruncatorClassTruncate a UTF-8 string to a some maximum number of bytes, codepoints, or glyphs.PhutilUTF8TestCaseClassTest cases for functions in utf8.php.PhutilUtilsTestCaseClassTest cases for functions in utils.php.ppull()FunctionAccess a property on a list of objects. Short for "property pull", this function works just like @{function:mpull}, except that it accesses object properties instead of methods. This function simplifies a common type of mapping operation:TestAbstractDirectedGraphClass

This client talks to a PHP process which serves as a proxy in front of a Mercurial server process. The PHP proxy allows multiple clients to use the same Mercurial server.ArcanistHgProxyServerClassServer which @{class:ArcanistHgProxyClient} clients connect to. This server binds to a Mercurial working copy and creates a Mercurial process and a unix domain socket in that working copy.
