The licenses granted in Section 2.1 with respect to any Contribution
become effective for each Contribution on the date the Contributor first
distributes such Contribution.
2.3. Limitations on Grant Scope
The licenses granted in this Section 2 are the only rights granted under
this License. No additional rights or licenses will be implied from the
distribution or licensing of Covered Software under this License.
Notwithstanding Section 2.1(b) above, no patent license is granted by a
Contributor:
a. for any code that a Contributor has removed from Covered Software; or
b. for infringements caused by: (i) Your and any other third party's
modifications of Covered Software, or (ii) the combination of its
Contributions with other software (except as part of its Contributor
Version); or
c. under Patent Claims infringed by Covered Software in the absence of
its Contributions.
This License does not grant any rights in the trademarks, service marks,
or logos of any Contributor (except as may be necessary to comply with
the notice requirements in Section 3.4).
2.4. Subsequent Licenses
No Contributor makes additional grants as a result of Your choice to
distribute the Covered Software under a subsequent version of this
License (see Section 10.2) or under the terms of a Secondary License (if
permitted under the terms of Section 3.3).
2.5. Representation
Each Contributor represents that the Contributor believes its
Contributions are its original creation(s) or it has sufficient rights to
grant the rights to its Contributions conveyed by this License.
2.6. Fair Use
This License is not intended to limit any rights You have under
applicable copyright doctrines of fair use, fair dealing, or other
equivalents.
2.7. Conditions
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
Section 2.1.
3. Responsibilities
3.1. Distribution of Source Form
All distribution of Covered Software in Source Code Form, including any
Modifications that You create or to which You contribute, must be under
the terms of this License. You must inform recipients that the Source
Code Form of the Covered Software is governed by the terms of this
License, and how they can obtain a copy of this License. You may not
attempt to alter or restrict the recipients' rights in the Source Code
Form.
3.2. Distribution of Executable Form
If You distribute Covered Software in Executable Form then:
a. such Covered Software must also be made available in Source Code Form,
as described in Section 3.1, and You must inform recipients of the
Executable Form how they can obtain a copy of such Source Code Form by
reasonable means in a timely manner, at a charge no more than the cost
of distribution to the recipient; and
b. You may distribute such Executable Form under the terms of this
License, or sublicense it under different terms, provided that the
license for the Executable Form does not attempt to limit or alter the
recipients' rights in the Source Code Form under this License.
3.3. Distribution of a Larger Work
You may create and distribute a Larger Work under terms of Your choice,
provided that You also comply with the requirements of this License for
the Covered Software. If the Larger Work is a combination of Covered
Software with a work governed by one or more Secondary Licenses, and the
Covered Software is not Incompatible With Secondary Licenses, this
License permits You to additionally distribute such Covered Software
under the terms of such Secondary License(s), so that the recipient of
the Larger Work may, at their option, further distribute the Covered
Software under the terms of either this License or such Secondary
License(s).
3.4. Notices
You may not remove or alter the substance of any license notices
(including copyright notices, patent notices, disclaimers of warranty, or
limitations of liability) contained within the Source Code Form of the
Covered Software, except that You may alter any license notices to the
extent required to remedy known factual inaccuracies.
3.5. Application of Additional Terms
You may choose to offer, and to charge a fee for, warranty, support,
indemnity or liability obligations to one or more recipients of Covered
Software. However, You may do so only on Your own behalf, and not on
behalf of any Contributor. You must make it absolutely clear that any
such warranty, support, indemnity, or liability obligation is offered by
You alone, and You hereby agree to indemnify every Contributor for any
liability incurred by such Contributor as a result of warranty, support,
indemnity or liability terms You offer. You may include additional
disclaimers of warranty and limitations of liability specific to any
jurisdiction.
4. Inability to Comply Due to Statute or Regulation
If it is impossible for You to comply with any of the terms of this License
with respect to some or all of the Covered Software due to statute,
judicial order, or regulation then You must: (a) comply with the terms of
this License to the maximum extent possible; and (b) describe the
limitations and the code they affect. Such description must be placed in a
text file included with all distributions of the Covered Software under
this License. Except to the extent prohibited by statute or regulation,
such description must be sufficiently detailed for a recipient of ordinary
skill to be able to understand it.
5. Termination
5.1. The rights granted under this License will terminate automatically if You
fail to comply with any of its terms. However, if You become compliant,
then the rights granted under this License from a particular Contributor
are reinstated (a) provisionally, unless and until such Contributor
explicitly and finally terminates Your grants, and (b) on an ongoing
basis, if such Contributor fails to notify You of the non-compliance by
some reasonable means prior to 60 days after You have come back into
compliance. Moreover, Your grants from a particular Contributor are
reinstated on an ongoing basis if such Contributor notifies You of the
non-compliance by some reasonable means, this is the first time You have
received notice of non-compliance with this License from such
Contributor, and You become compliant prior to 30 days after Your receipt
of the notice.
5.2. If You initiate litigation against any entity by asserting a patent
infringement claim (excluding declaratory judgment actions,
counter-claims, and cross-claims) alleging that a Contributor Version
directly or indirectly infringes any patent, then the rights granted to
You by any and all Contributors for the Covered Software under Section
2.1 of this License shall terminate.
5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
license agreements (excluding distributors and resellers) which have been
validly granted by You or Your distributors under this License prior to
termination shall survive termination.
6. Disclaimer of Warranty
Covered Software is provided under this License on an "as is" basis,
without warranty of any kind, either expressed, implied, or statutory,
including, without limitation, warranties that the Covered Software is free
of defects, merchantable, fit for a particular purpose or non-infringing.
The entire risk as to the quality and performance of the Covered Software
is with You. Should any Covered Software prove defective in any respect,
You (not any Contributor) assume the cost of any necessary servicing,
repair, or correction. This disclaimer of warranty constitutes an essential
part of this License. No use of any Covered Software is authorized under
this License except under this disclaimer.
7. Limitation of Liability
Under no circumstances and under no legal theory, whether tort (including
negligence), contract, or otherwise, shall any Contributor, or anyone who
distributes Covered Software as permitted above, be liable to You for any
direct, indirect, special, incidental, or consequential damages of any
character including, without limitation, damages for lost profits, loss of
goodwill, work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses, even if such party shall have been
informed of the possibility of such damages. This limitation of liability
shall not apply to liability for death or personal injury resulting from
such party's negligence to the extent applicable law prohibits such
limitation. Some jurisdictions do not allow the exclusion or limitation of
incidental or consequential damages, so this exclusion and limitation may
not apply to You.
8. Litigation
Any litigation relating to this License may be brought only in the courts
of a jurisdiction where the defendant maintains its principal place of
business and such litigation shall be governed by laws of that
jurisdiction, without reference to its conflict-of-law provisions. Nothing
in this Section shall prevent a party's ability to bring cross-claims or
counter-claims.
9. Miscellaneous
This License represents the complete agreement concerning the subject
matter hereof. If any provision of this License is held to be
unenforceable, such provision shall be reformed only to the extent
necessary to make it enforceable. Any law or regulation which provides that
the language of a contract shall be construed against the drafter shall not
be used to construe this License against a Contributor.
10. Versions of the License
10.1. New Versions
Mozilla Foundation is the license steward. Except as provided in Section
10.3, no one other than the license steward has the right to modify or
publish new versions of this License. Each version will be given a
distinguishing version number.
10.2. Effect of New Versions
You may distribute the Covered Software under the terms of the version
of the License under which You originally received the Covered Software,
or under the terms of any subsequent version published by the license
steward.
10.3. Modified Versions
If you create software not governed by this License, and you want to
create a new license for such software, you may create and use a
modified version of this License if you rename the license and remove
any references to the name of the license steward (except to note that
such modified license differs from this License).
10.4. Distributing Source Code Form that is Incompatible With Secondary
Licenses If You choose to distribute Source Code Form that is
Incompatible With Secondary Licenses under the terms of this version of
the License, the notice described in Exhibit B of this License must be
attached.

golang-lru
==========
This provides the `lru` package which implements a fixed-size
thread safe LRU cache. It is based on the cache in Groupcache.
Documentation
=============
Full docs are available on [Go Packages](https://pkg.go.dev/github.com/hashicorp/golang-lru/v2)
LRU cache example
=================
```go
package main
import (
"fmt"
"github.com/hashicorp/golang-lru/v2"
)
func main() {
l, _ := lru.New[int, any](128)
for i := 0; i < 256; i++ {
l.Add(i, nil)
}
if l.Len() != 128 {
panic(fmt.Sprintf("bad len: %v", l.Len()))
}
}
```
Expirable LRU cache example
===========================
```go
package main
import (
"fmt"
"time"
"github.com/hashicorp/golang-lru/v2/expirable"
)
func main() {
// make cache with 10ms TTL and 5 max keys
cache := expirable.NewLRU[string, string](5, nil, time.Millisecond*10)
// set value under key1.
cache.Add("key1", "val1")
// get value under key1
r, ok := cache.Get("key1")
// check for OK value
if ok {
fmt.Printf("value before expiration is found: %v, value: %q\n", ok, r)
}
// wait for cache to expire
time.Sleep(time.Millisecond * 12)
// get value under key1 after key expiration
r, ok = cache.Get("key1")
fmt.Printf("value after expiration is found: %v, value: %q\n", ok, r)
// set value under key2, would evict old entry because it is already expired.
cache.Add("key2", "val2")
fmt.Printf("Cache len: %d\n", cache.Len())
// Output:
// value before expiration is found: true, value: "val1"
// value after expiration is found: false, value: ""
// Cache len: 1
}
```

// Package lru provides three different LRU caches of varying sophistication.
//
// Cache is a simple LRU cache. It is based on the LRU implementation in
// groupcache: https://github.com/golang/groupcache/tree/master/lru
//
// TwoQueueCache tracks frequently used and recently used entries separately.
// This avoids a burst of accesses from taking out frequently used entries, at
// the cost of about 2x computational overhead and some extra bookkeeping.
//
// ARCCache is an adaptive replacement cache. It tracks recent evictions as well
// as recent usage in both the frequent and recent caches. Its computational
// overhead is comparable to TwoQueueCache, but the memory overhead is linear
// with the size of the cache.
//
// ARC has been patented by IBM, so do not use it if that is problematic for
// your program. For this reason, it is in a separate go module contained within
// this repository.
//
// All caches in this package take locks while operating, and are therefore
// thread-safe for consumers.

PACKAGE
package shellquote
import "github.com/kballard/go-shellquote"
Shellquote provides utilities for joining/splitting strings using sh's
word-splitting rules.
VARIABLES
var (
UnterminatedSingleQuoteError = errors.New("Unterminated single-quoted string")
UnterminatedDoubleQuoteError = errors.New("Unterminated double-quoted string")
UnterminatedEscapeError = errors.New("Unterminated backslash-escape")
)
FUNCTIONS
func Join(args ...string) string
Join quotes each argument and joins them with a space. If passed to
/bin/sh, the resulting string will be split back into the original
arguments.
func Split(input string) (words []string, err error)
Split splits a string according to /bin/sh's word-splitting rules. It
supports backslash-escapes, single-quotes, and double-quotes. Notably it
does not support the $'' style of quoting. It also doesn't attempt to
perform any other sort of expansion, including brace expansion, shell
expansion, or pathname expansion.
If the given input has an unterminated quoted string or ends in a
backslash-escape, one of UnterminatedSingleQuoteError,
UnterminatedDoubleQuoteError, or UnterminatedEscapeError is returned.

uint128
-------
[![GoDoc](https://godoc.org/github.com/lukechampine/uint128?status.svg)](https://godoc.org/github.com/lukechampine/uint128)
[![Go Report Card](http://goreportcard.com/badge/github.com/lukechampine/uint128)](https://goreportcard.com/report/github.com/lukechampine/uint128)
```
go get lukechampine.com/uint128
```
`uint128` provides a high-performance `Uint128` type that supports standard arithmetic
operations. Unlike `math/big`, operations on `Uint128` values always produce new values
instead of modifying a pointer receiver. A `Uint128` value is therefore immutable, just
like `uint64` and friends.
The name `uint128.Uint128` stutters, so I recommend either using a "dot import"
or aliasing `uint128.Uint128` to give it a project-specific name. Embedding the type
is not recommended, because methods will still return `uint128.Uint128`; this means that,
if you want to extend the type with new methods, your best bet is probably to copy the
source code wholesale and rename the identifier. ¯\\\_(ツ)\_/¯
# Benchmarks
Addition, multiplication, and subtraction are on par with their native 64-bit
equivalents. Division is slower: ~20x slower when dividing a `Uint128` by a
`uint64`, and ~100x slower when dividing by a `Uint128`. However, division is
still faster than with `big.Int` (for the same operands), especially when
dividing by a `uint64`.

= Design Notes
== Problems:
Translating C to Go is harder than it looks.
Jan says: It's impossible in the general case to turn C char* into Go
[]byte. It's possible to do it probably often for concrete C code
cases - based also on author's C coding style. The first problem this
runs into is that Go does not guarantee that the backing array will
keep its address stable due to Go movable stacks. C expects the
opposite, a pointer never magically modifies itself, so some code will
fail.
INSERT CODE EXAMPLES ILLUSTRATING THE PROBLEM HERE
== How the parser works
There are no comment nodes in the C AST. Instead every cc.Token has a
Sep field: https://godoc.org/modernc.org/cc/v3#Token
It captures, when configured to do so, all white space preceding the
token, combined, including comments, if any. So we have all white
space/comments information for every token in the AST. A final white
space/comment, preceding EOF, is available as field TrailingSeperator
in the AST: https://godoc.org/modernc.org/cc/v3#AST.
To get the lexically first white space/comment for any node, use
tokenSeparator():
https://gitlab.com/cznic/ccgo/-/blob/6551e2544a758fdc265c8fac71fb2587fb3e1042/v3/go.go#L1476
The same with a default value is comment():
https://gitlab.com/cznic/ccgo/-/blob/6551e2544a758fdc265c8fac71fb2587fb3e1042/v3/go.go#L1467
== Looking forward
Eric says: In my visualization of how the translator would work, the
output of a ccgo translation of a module at any given time is a file
of pseudo-Go code in which some sections may be enclosed by a Unicode
bracketing character (presently using the guillemot quotes U+ab and
U+bb) meaning "this is not Go yet" that intentionally makes the Go
compiler barf. This expresses a color on the AST nodes.
So, for example, if I'm translating hello.c with a ruleset that does not
include print -> fmt.Printf, this:
---------------------------------------------------------
#include <stdio>
/* an example comment */
int main(int argc, char *argv[])
{
printf("Hello, World")
}
---------------------------------------------------------
becomes this without any explicit rules at all:
---------------------------------------------------------
«#include <stdio>»
/* an example comment */
func main
{
«printf(»"Hello, World"!\n"«)»
}
---------------------------------------------------------
Then, when the rule print -> fmt.Printf is added, it becomes
---------------------------------------------------------
import (
"fmt"
)
/* an example comment */
func main
{
fmt.Printf("Hello, World"!\n")
}
---------------------------------------------------------
because with that rule the AST node corresponding to the printf
call can be translated and colored "Go". This implies an import
of fmt. We observe that there are no longer C-colored spans
and drop the #includes.
