String prints the argument as the name if present, otherwise as the value.

ScanSnapshot scans the Reader for the output from runtime.Stack() in br. Returns nil *Snapshot if no stack trace was detected. If a Snapshot is retu

Aggregate merges similar goroutines into buckets. The buckets are ordered in library provided order of relevancy. You can reorder at your choosing.

less compares two Stack, where the ones that are less are more important, so they come up front. A Stack with more private functions is 'less' so it

BucketHeader prints the header of a goroutine signature.

SnapshotHandler implements http.HandlerFunc to returns a panicparse HTML format for a snapshot of the current goroutines. For best results, compile t

equal returns true only if both arguments are exactly equal.

similar returns true if the two Arg are equal or almost but not quite equal.

similarGoroutines compares slice of Goroutine to be similar enough. Warning: it mutates inputs.

PanicOutputs returns a map of the output of every subcommands. panic is built with inlining disabled. The subcommand "race" is built with the race d

atou is a fast Atoi() function. It is a very simplified version of strconv.Atoi() that it never go into the slow path and it operates on []byte inste

updateLocations initializes LocalSrcPath, RelSrcPath, Location and ImportPath. goroot, localgoroot, localgomod, gomodImportPath and gopaths are expec

SleepString returns a string "N-M minutes" if the goroutine(s) slept for a long time. Returns an empty string otherwise.

GetGoMinorVersion returns the Go1 minor version. Returns 0 for a developer build, panics if can't parse the version. Ignores the revision (go1.<mino

Init parses the raw function call line from a goroutine stack trace. Go stack traces print a mangled function call, this wrapper unmangle the string

getGOPATHs returns parsed GOPATH or its default, using "/" as path separator.

parseFunc only return an error if it also returns true. Uses reFunc.

IsUsingModules returns if go modules are enabled. It reads the current value of GO111MODULES.

StackLines prints one complete stack trace, without the header.

StaticPanicwebOutput returns a constant version of panicweb output for use in benchmarks.

lineToByteOffsets extract the line number into raw file offset. Inserts a dummy 0 at offset 0 so line offsets can be 1 based.

Utility functions.

parseFile only return an error if also processing a Call. Uses reFile.

splitPath splits a path using "/" as separator into its components. The first item has its initial path separator kept.

trimLeftSpace is the faster equivalent of bytes.TrimLeft(s, "\t ").

IsRace returns true if a race detector stack trace was found. Otherwise, it is a normal goroutines snapshot. When a race condition was detected, it

Main is implemented here so both 'pp' and 'panicparse' executables can be compiled. This is to work around the Perl Package manager 'pp' that is prein

augment processes source files to improve calls to be more descriptive. It modifies goroutines in place. It requires calling guessPaths() to work pro

build builds to a temporary file and returns the path to it.

calcBucketsLengths returns the maximum length of the source lines and package names.

execRun runs a command and returns the combined output. It ignores the exit code, since it's meant to run panic, which crashes by design.

getBuckets returns a slice for testing.

getPanicParseDir returns the path to the root directory of panicparse package, using "/" as path separator.

getSrcBranchURL returns a link to the source on the web and the tag name for the package version, if possible.

Init initializes RemoteSrcPath, SrcName, DirName and Line. For test main, it initializes Location only with Stdlib. It does its best educated guess

isGoModule returns the string to the directory containing a go.mod file, and the go import path it represents, if found.

isRootedIn returns a root if the file split in parts exists under root. Uses "/" as path separator.

merge merges two similar Args, zapping out differences.

process copies stdin to stdout and processes any "panic: " line found. If html is used, a stack trace is written to this file instead.

unsafeString performs an unsafe conversion from a []byte to a string. The returned string will share the underlying memory with the []byte which thus

walk traverses all non-aggregate arguments in the Args struct, calling the provided visitor function with each Arg.

Callback calls back a function through an external then internal function.

Compile compiles sources into an executable.

GetAsync does an HTTP GET to the URL but leaves the actual fetching to a goroutine.

isFile returns true if the path is a valid file.

routineColor returns the color for the header of the goroutines bucket.

symbol is the hashtag to use to refer to the symbol when looking at documentation. All of godoc/gddo, pkg.go.dev and golang.org/godoc use the same sy

Private stuff.

trimCurlyBrackets is the faster equivalent of bytes.TrimRight(bytes.TrimLeft(s, "{"), "}"). The function also returns the number of curly brackets tri

GoroutineHeader prints the header of a goroutine.

PanicwebOutput returns the output of panicweb with inlining disabled. The function panics if any internal error occurs.

Pànic panics.

StaticPanicRaceOutput returns a constant version of 'panic race' output.

augmentCall walks the function and populate call accordingly.

augmentGoroutine processes source files to improve call to be more descriptive. It modifies the routine.

calcGoroutinesLengths returns the maximum length of the source lines and package names.

callLine prints one stack line.

equal returns true only if both signatures are exactly equal.

extractArgumentsType returns the name of the type of each input argument.

fieldToType returns the type name and whether if it's an ellipsis.

fill reads a new chunk into the buffer.
