refactor!: rename to pdfgrab, plus release automation and a repaired CHANGELOG#25hallelx2 wants to merge 4 commits into
Conversation
CHANGELOG.md was 1866 lines holding 29 version headings for 8 versions: [Unreleased] six times, [0.3.1] six times, [0.3.0] five times. abe3742 (#17) is where it happened -- the file went 434 -> 1768 lines in one commit, because the edit prepended a new section plus the entire preceding file rather than merging into it, and every later edit repeated the pattern one level deeper. Each copy's final section was truncated where the next copy's preamble began, so the nesting also lost text: the MergeSplitTokens bullet ends mid-sentence at "a genuine column gutter -- the" followed by "# Changelog". Rebuilt from 7224c2c, the last commit with a clean file, with the released sections taken verbatim from there. The newer entries were recovered from the truncated copies and from the commits themselves. Two sections did not exist before and do now. 0.4.0 had no entry at all. It was tagged at 27d6c60 against a changelog whose newest heading was 0.3.1, so XToleranceRatio and UseExplicitSpaces shipped undocumented. Written from the commit. 0.5.0 collects the thirteen commits since that tag. It is a minor bump rather than a patch because DefaultWordOpts() now enables UseExplicitSpaces, which changes word segmentation for every existing caller -- called out under its own "Changed (behaviour)" heading rather than buried in the fixes. The ICDAR 2013 numbers and the 0.362 -> 0.935 oracle result are recorded there too, since the conclusion they support (the gap is table structure, not text extraction) is the reason the release exists in the shape it does. Version compare/tag links are restored for every version, including the two that had none.
No behaviour change -- alignment and spacing only. The drift accumulated because nothing checked for it; the CI gate added alongside this stops it recurring.
Every tag from v0.0.1 to v0.4.0 was pushed by hand. There was no GitHub Release behind any of them, nothing verified the tree before the tag became permanent, and pkg.go.dev only picked pdftable up whenever its next scan happened to run. A Go module tag cannot be moved once the proxy has served it, so "verify after tagging" is not a recoverable order of operations. Ported from llmgate's release.yml, which already solved this: semver validation, go.mod tidiness, vet + build + race tests, GitHub Release with generated notes, then a proxy warm so pkg.go.dev indexes the version immediately. One step is new here. The release fails if CHANGELOG.md has no section matching the tag, because shipping v0.4.0 with no entry is exactly the failure this repo already had, and a grep is enough to make it impossible. The gofmt gate runs on ubuntu only -- gofmt is platform-independent, so running it across the three-OS matrix would report identical drift three times.
Reviewer's GuideAdds automated release workflow gated on CHANGELOG completeness, enforces gofmt in CI, and rebuilds the CHANGELOG for v0.4.0 and v0.5.0 while making minor formatting-only Go code cleanups. File-Level Changes

**suggestion (bug_risk):** Suppressing curl failures completely may hide useful diagnostics if proxy warming fails
All three `curl` calls use `|| true`, so persistent proxy or sum.golang.org failures (e.g., bad module path or misconfig) will be completely silent in the workflow logs. Consider at least surfacing non-2xx responses (e.g., via `-sS` and a custom error message) or limiting `|| true` to known transient/expected failures so you retain useful diagnostics when something is actually wrong.

Limit contents: write to the publication job.
The validation commands execute with a write-capable GITHUB_TOKEN. Compromised repository code or tests can use that token before the release is created. Split validation and publication into separate jobs. Set validation to contents: read; grant contents: write only to the release job. GitHub recommends explicit minimum permissions for workflows.

GitHub Actions checkout persist-credentials default documentation softprops action-gh-release token default
💡 Result:
For the actions/checkout action, the persist-credentials input defaults to true [1][2][3]. When set to true, the action configures the local Git client with the provided authentication token (or SSH key), enabling your workflow scripts to run authenticated Git commands (such as git push or git pull) [1][2][3]. The token is stored in the local Git configuration and is removed during the post-job cleanup phase [1][2][3]. You can opt-out of this behavior by explicitly setting persist-credentials: false in your workflow YAML [1][2]. For the softprops/action-gh-release action, the token input defaults to ${{ github.token }} when omitted [4][5][6]. This utilizes the built-in GITHUB_TOKEN provided by GitHub Actions for the workflow job [4][5][6]. A non-empty explicit token value will override this default [4][5][6]. If you need to pass an empty string to treat the token as explicitly unset, you should avoid passing it as an input or use an expression to handle the logic, as passing an empty string literally can be treated differently depending on the implementation [5][6][7]. Note that if you are running workflows on the release event, you may need a personal access token (PAT) instead of the default GITHUB_TOKEN, as the default token does not trigger subsequent workflows [5][6][8].

Pin workflow actions and disable checkout credential persistence.
Because this workflow grants contents: write, pin all three actions to verified full commit SHAs. Set persist-credentials: false for actions/checkout. softprops/action-gh-release already defaults token to ${{ github.token }}, so an explicit token is optional.

golang.org/x/mod/semver documentation valid versions leading zeros prerelease empty identifiers
💡 Result:
The golang.org/x/mod/semver package implements semantic versioning with specific rules and behaviors described in its documentation and source code [1][2]. Leading Zeros Major, minor, and patch components must be decimal integers without extra leading zeros (e.g., "v01.0.0" is invalid) [2]. Regarding pre-release identifiers, the package follows the Semantic Versioning 2.0.0 specification, which dictates that numeric pre-release identifiers must not include leading zeros [2][3][4]. The package enforces this through parsing logic that rejects numeric identifiers with leading zeros [3]. Prerelease and Empty Identifiers A semantic version string accepted by this package follows the form vMAJOR[.MINOR[.PATCH[-PRERELEASE][+BUILD]]] [2]. - Prerelease: A pre-release string starts with a hyphen [5][2]. It consists of a series of dot-separated identifiers [2]. - Empty Identifiers: The package follows the rule that pre-release and build metadata identifiers must not be empty [2][3][4]. The internal parsing functions (such as parsePrerelease and parseBuild) explicitly check for empty identifiers between dots or surrounding hyphens/plus signs and will return an invalid status if they are found [3]. The package maintains strict adherence to these rules to ensure compatibility within the Go module ecosystem [2]. While it generally follows SemVer 2.0.0, it includes two specific deviations: it mandates a leading "v" prefix (e.g., "v1.0.0"), and it supports vMAJOR and vMAJOR.MINOR as shorthand for vMAJOR.0.0 and vMAJOR.MINOR.0, respectively [2].

Go module proxy protocol .info .mod .zip pkg.go.dev indexing source download behavior
💡 Result:
The Go module proxy protocol is a simple, stateless HTTP-based API that allows the go command to retrieve module information and source code from servers called module proxies [1][2]. Proxies serve content via GET requests to specific endpoints, meaning they can be implemented as simple web servers or even static file systems [1][2]. The standard endpoints defined by the protocol are: - /{module}/@v/list: Returns a list of all known versions for a module, one per line [2]. - /{module}/@v/{version}.info: Returns a JSON-encoded file containing metadata about the module version, such as the exact version string and timestamp [3][4]. - /{module}/@v/{version}.mod: Returns the content of the module's go.mod file [3][2]. If the original module lacks a go.mod file, the proxy is expected to provide a synthetic one [5][6]. - /{module}/@v/{version}.zip: Returns the module source code as a ZIP archive [3][4]. Each file in the zip must be prefixed with the module path and version (e.g., example.com/mod@v1.0.0/) [2]. The Go command uses the GOPROXY environment variable to determine which proxies to contact [5][6]. When resolving a module, it checks the defined proxies in order; if a requested file returns a 404 or 410, it typically moves to the next configured proxy [5][6]. Regarding indexing and pkg.go.dev: - Indexing: The service index.golang.org maintains a public feed of new module versions that become available on proxy.golang.org [7][8]. - Discovery: Pkg.go.dev monitors this index to discover new modules [9][10]. A worker process consumes these updates, downloads the corresponding module source code from proxy.golang.org using the module proxy protocol, and processes it to extract documentation, licenses, and other metadata for the website [9][10]. - User Requests: If a module is not yet indexed, users can trigger discovery by visiting the module's page on pkg.go.dev and clicking a "Request" button, which initiates the process [10]. In summary, the protocol provides a standardized, efficient way to distribute Go modules, while pkg.go.dev leverages the index service and proxy mirror to automate the discovery and documentation of the Go ecosystem [7][9][10].

site:go.dev/ref/mod module proxy .zip pkg.go.dev index module version download
💡 Result:
The Go module proxy protocol defines a specific URL structure for downloading module source code as a zip archive. To download a specific version of a module from a proxy server (such as proxy.golang.org), you can perform an HTTP GET request to the following endpoint: //@v/.zip In this URL pattern: - is the module path (often with characters escaped if they contain uppercase letters). - is the semantic version of the module. For example, to download version v1.0.0 of a module named example.com/my/mod, the request URL would be: https://proxy.golang.org/example.com/my/mod/@v/v1.0.0.zip The module proxy protocol also supports other endpoints for retrieving information, such as: - //@v/.info: Returns JSON metadata about the version. - //@v/.mod: Returns the go.mod file for that version. - //@latest: Returns the latest version of the module. When using these endpoints, note that the Go command-line tool manages these interactions automatically based on the GOPROXY environment variable [1]. If you are interacting with the proxy manually, ensure that any uppercase letters in the module path are replaced with their lowercase equivalent preceded by an exclamation mark (e.g., example.com/User/Mod becomes example.com/!user/!mod).

site:go.dev/ref/mod "go mod download" "-json" errors exit status
💡 Result:
When running go mod download -json, the Go command provides module information in JSON format for successful operations [1]. If the command encounters an error, it exits with a non-zero status code [1]. In Go, when a command fails, it reports an error message to standard error (stderr). If you are using the -json flag, the command is intended to output structured information; however, if the command fails, the output may be incomplete, or the error details may be printed to stderr instead of being encapsulated within the JSON stream. Common causes for go mod download failures include: 1. Missing or inconsistent information in go.mod or go.sum files [1]. 2. Network issues or unavailability of modules through configured proxies in GOPROXY [1]. 3. Multiple modules providing the same package, or no modules found for a requested package [1]. To resolve errors, you can typically use the go mod tidy command to update and correct your go.mod and go.sum files [1]. If you encounter specific issues, ensure that your environment's GOPROXY settings are correctly configured to reach the required module repositories [1].

site:go.dev/ref/mod proxy.golang.org pkg.go.dev index.golang.org source zip module version
💡 Result:
The services proxy.golang.org, pkg.go.dev, and index.golang.org play distinct roles in the Go module ecosystem: proxy.golang.org This is an official module proxy server maintained by Google. When the go command needs to download a module, it checks the proxy defined by the GOPROXY environment variable [1]. The proxy acts as a cache and a reliable source for module versions, allowing the go command to download modules without needing direct access to version control systems [1]. pkg.go.dev This is a website that serves as a documentation hub and discovery service for Go packages. It indexes public Go modules and provides documentation, helping developers find and understand available packages. index.golang.org This service provides an index of new modules as they are published to the proxy. It allows services like pkg.go.dev to monitor the proxy for new content, enabling the discovery and indexing of new module versions in real-time. Protocol and Source Files The Go module proxy protocol defines how the go command interacts with proxies. When a module is requested, the proxy serves information and files based on the requested version. Specifically, when a module version is requested, the proxy can provide a.zip file (the source zip) containing the module's source code, which the go command downloads and caches locally [1]. These interactions occur over HTTP, and the go command automatically handles requests for module metadata and source files from the configured proxy [1].

"pdftable" names one of the six things this library does. It also does text extraction at 0.01pt pdfplumber parity, real Adobe AFM metrics for the standard-14 fonts, Symbol and ZapfDingbats encodings, size-relative word clustering, and viewer-space geometry for citation highlighting -- with rasterisation and an addressing layer next. Someone looking for a Go PDF text library with exact coordinates does not find this one, and if they do they assume it is table-only and move on. Now is the only cheap moment. A Go module path IS its import path, so a rename means every consumer rewrites imports and pkg.go.dev starts over. Pre-1.0 with one real consumer that cost is a single PR; after the OSS launch, with docs and SDK quickstarts referencing it, it is a deprecation cycle. v0.5.0 is not tagged yet, so the rename and the release land as one event rather than two migrations. pdfgrab is the umbrella, not a sibling: table finding, the coming render package and the coming addressing layer all sit under it, so there is one name to know rather than a family to explain. The selection API this is heading toward reads naturally at the root -- pdfgrab.Open, doc.At, doc.Resolve, doc.Tables. Module path, package clauses, the CLI directory, the separate bench module, the Python harness and every doc move together. No API surface changes: this is a rename, and the only reason it carries a `!` is the import path. BREAKING CHANGE: the module path is now github.com/hallelx2/pdfgrab and the package is `pdfgrab`. Update imports and qualified identifiers; nothing else changed. github.com/hallelx2/pdftable@v0.4.0 stays published and resolvable, so existing builds keep working until they choose to move.

Go command documentation for go buildbehavior when given multiple packages including a main package, and softprops/action-gh-releasefiles input documentation
💡 Result:
The behavior of go build when multiple packages are specified, including a main package, depends on whether the -o flag is used and how it is configured [1][2]. When no -o flag is specified: Go build compiles the specified packages and their dependencies but discards the resulting objects [3][2]. This serves primarily as a check to ensure that all specified packages can be successfully built [1][4]. It does not produce executable files, even if main packages are included in the list [3][2]. When the -o flag is used: The behavior depends on whether the target specified by -o is a directory or a file [1][2]. 1. If the target is an existing directory (or the string ends in a path separator), Go build writes the resulting executables for all main packages found within the specified list to that directory [1][2]. Non-main packages are still compiled and then discarded [1][2]. 2. If the target is a single file path, Go requires that exactly one main package is being built [1]. If the list contains multiple packages or zero main packages, the command will fail with an error [1][5]. Regarding the softprops/action-gh-release action, the files input is used to specify the assets to upload to a GitHub release [6][7]. - The input accepts a newline-delimited list of glob expressions [6][8]. - You can provide file paths directly or use standard glob patterns [6][9]. - The paths are resolved relative to the working_directory input, which defaults to the GitHub workspace root (${{ github.workspace }}) if omitted [6][10]. - If you need to match literal filenames that contain glob metacharacters (such as [ or ]), these characters must be escaped in your pattern [6][7]. - On Windows, the action accepts both / and \ as path separators [6][10].

Everything needed to cut v0.5.0 — under a new name.
1. Rename:
pdftable→pdfgrab"pdftable" names one of the six things this library does. It also does text extraction at 0.01pt pdfplumber parity, real Adobe AFM metrics for the standard-14 fonts, Symbol/ZapfDingbats encodings, size-relative word clustering, and viewer-space geometry for citation highlighting — with

Every tag from v0.0.1 to v0.4.0 was pushed by hand — no GitHub Release, nothing verifying the tree before the tag became permanent, no proxy warm. A Go module tag can't be moved once the proxy has served it, so "verify after tagging" isn't a recoverable order of operations.
Ported from llmgate's
release.yml. One step is new: the release fails ifCHANGELOG.mdhas no section matching the tag — shipping v0.4.0 undocumented is a failure this repo already had.4. The CLI version was lying
pdfgrab versionwas a hardcoded literal pinned atv0.3.0— and the test asserted that same literal, so the CLI reported v0.3.0 for the entire v0.4.0 release and the test agreed with it.Now
var version = "dev", injected by the release workflow via-ldflags "-X main.version=$GITHUB_REF_NAME". The test asserts the shape (names the tool, carries a version) rather than a literal someone has to remember to bump.5. Also
gofmton eight drifted files, plus agofmtgate on every PR so it can't recur.Verification
