Additional Definitions. + + As used herein, "this License" refers to version 3 of the GNU Lesser +General Public License, and the "GNU GPL" refers to version 3 of the GNU +General Public License. + + "The Library" refers to a covered work governed by this License, +other than an Application or a Combined Work as defined below. + + An "Application" is any work that makes use of an interface provided +by the Library, but which is not otherwise based on the Library. +Defining a subclass of a class defined by the Library is deemed a mode +of using an interface provided by the Library. + + A "Combined Work" is a work produced by combining or linking an +Application with the Library. The particular version of the Library +with which the Combined Work was made is also called the "Linked +Version". + + The "Minimal Corresponding Source" for a Combined Work means the +Corresponding Source for the Combined Work, excluding any source code +for portions of the Combined Work that, considered in isolation, are +based on the Application, and not on the Linked Version. + + The "Corresponding Application Code" for a Combined Work means the +object code and/or source code for the Application, including any data +and utility programs needed for reproducing the Combined Work from the +Application, but excluding the System Libraries of the Combined Work. + + 1. Exception to Section 3 of the GNU GPL. + + You may convey a covered work under sections 3 and 4 of this License +without being bound by section 3 of the GNU GPL. + + 2. Conveying Modified Versions. + + If you modify a copy of the Library, and, in your modifications, a +facility refers to a function or data to be supplied by an Application +that uses the facility (other than as an argument passed when the +facility is invoked), then you may convey a copy of the modified +version: + + a) under this License, provided that you make a good faith effort to + ensure that, in the event an Application does not supply the + function or data, the facility still operates, and performs + whatever part of its purpose remains meaningful, or + + b) under the GNU GPL, with none of the additional permissions of + this License applicable to that copy. + + 3. Object Code Incorporating Material from Library Header Files. + + The object code form of an Application may incorporate material from +a header file that is part of the Library. You may convey such object +code under terms of your choice, provided that, if the incorporated +material is not limited to numerical parameters, data structure +layouts and accessors, or small macros, inline functions and templates +(ten or fewer lines in length), you do both of the following: + + a) Give prominent notice with each copy of the object code that the + Library is used in it and that the Library and its use are + covered by this License. + + b) Accompany the object code with a copy of the GNU GPL and this license + document. + + 4. Combined Works. + + You may convey a Combined Work under terms of your choice that, +taken together, effectively do not restrict modification of the +portions of the Library contained in the Combined Work and reverse +engineering for debugging such modifications, if you also do each of +the following: + + a) Give prominent notice with each copy of the Combined Work that + the Library is used in it and that the Library and its use are + covered by this License. + + b) Accompany the Combined Work with a copy of the GNU GPL and this license + document. + + c) For a Combined Work that displays copyright notices during + execution, include the copyright notice for the Library among + these notices, as well as a reference directing the user to the + copies of the GNU GPL and this license document. + + d) Do one of the following: + + 0) Convey the Minimal Corresponding Source under the terms of this + License, and the Corresponding Application Code in a form + suitable for, and under terms that permit, the user to + recombine or relink the Application with a modified version of + the Linked Version to produce a modified Combined Work, in the + manner specified by section 6 of the GNU GPL for conveying + Corresponding Source. + + 1) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (a) uses at run time + a copy of the Library already present on the user's computer + system, and (b) will operate properly with a modified version + of the Library that is interface-compatible with the Linked + Version. + + e) Provide Installation Information, but only if you would otherwise + be required to provide such information under section 6 of the + GNU GPL, and only to the extent that such information is + necessary to install and execute a modified version of the + Combined Work produced by recombining or relinking the + Application with a modified version of the Linked Version. (If + you use option 4d0, the Installation Information must accompany + the Minimal Corresponding Source and Corresponding Application + Code. If you use option 4d1, you must provide the Installation + Information in the manner specified by section 6 of the GNU GPL + for conveying Corresponding Source.) + + 5. Combined Libraries. + + You may place library facilities that are a work based on the +Library side by side in a single library together with other library +facilities that are not Applications and are not covered by this +License, and convey such a combined library under terms of your +choice, if you do both of the following: + + a) Accompany the combined library with a copy of the same work based + on the Library, uncombined with any other library facilities, + conveyed under the terms of this License. + + b) Give prominent notice with the combined library that part of it + is a work based on the Library, and explaining where to find the + accompanying uncombined form of the same work. + + 6. Revised Versions of the GNU Lesser General Public License. + + The Free Software Foundation may publish revised and/or new versions +of the GNU Lesser General Public License from time to time. Such new +versions will be similar in spirit to the present version, but may +differ in detail to address new problems or concerns. + + Each version is given a distinguishing version number. If the +Library as you received it specifies that a certain numbered version +of the GNU Lesser General Public License "or any later version" +applies to it, you have the option of following the terms and +conditions either of that published version or of any later version +published by the Free Software Foundation. If the Library as you +received it does not specify a version number of the GNU Lesser +General Public License, you may choose any version of the GNU Lesser +General Public License ever published by the Free Software Foundation. + + If the Library as you received it specifies that a proxy can decide +whether future versions of the GNU Lesser General Public License shall +apply, that proxy's public statement of acceptance of any version is +permanent authorization for you to choose that version for the +Library. diff --git a/Makefile b/Makefile new file mode 100644 index 0000000..4c5e4e7 --- /dev/null +++ b/Makefile @@ -0,0 +1,89 @@ +.PHONY: build clean wipe test help + +# Default target +all: build + +# Build the binary +build: + @echo "Building s3-genindex..." + go build -o s3-genindex ./cmd/s3-genindex + @echo "Build complete: s3-genindex" + +# Run tests +test: + @echo "Running tests..." + go test -v ./... + @echo "Tests complete" + +# Run tests with coverage +test-coverage: + @echo "Running tests with coverage..." + go test -v -coverprofile=coverage.out ./... + go tool cover -html=coverage.out -o coverage.html + @echo "Coverage report generated: coverage.html" + +# Clean build artifacts +clean: + @echo "Cleaning build artifacts..." + rm -f s3-genindex + rm -f coverage.out coverage.html + @echo "Clean complete" + +# Wipe everything including test caches +wipe: clean + @echo "Wiping test cache and module cache..." + go clean -testcache + go clean -modcache + @echo "Wipe complete" + +# Install binary to $GOPATH/bin or $GOBIN +install: + @echo "Installing s3-genindex..." + go install ./cmd/s3-genindex + @echo "Install complete" + +# Format code +fmt: + @echo "Formatting code..." + go fmt ./... + @echo "Format complete" + +# Vet code for issues +vet: + @echo "Vetting code..." + go vet ./... + @echo "Vet complete" + +# Lint code (requires golangci-lint) +lint: + @echo "Linting code..." + @if command -v golangci-lint >/dev/null 2>&1; then \ + golangci-lint run; \ + else \ + echo "golangci-lint not found, skipping lint"; \ + fi + +# Run all checks +check: fmt vet lint test + @echo "All checks passed" + +# Run benchmarks +bench: + @echo "Running benchmarks..." + go test -bench=. ./... + +# Show help +help: + @echo "Available targets:" + @echo " build - Build the s3-genindex binary" + @echo " test - Run all tests" + @echo " test-coverage - Run tests with coverage report" + @echo " clean - Remove build artifacts" + @echo " wipe - Clean everything including caches" + @echo " install - Install binary to GOPATH/bin" + @echo " fmt - Format code" + @echo " vet - Vet code for issues" + @echo " lint - Lint code (requires golangci-lint)" + @echo " check - Run fmt, vet, lint, and test" + @echo " bench - Run benchmarks" + @echo " help - Show this help message" \ No newline at end of file diff --git a/README.md b/README.md new file mode 100644 index 0000000..20fe805 --- /dev/null +++ b/README.md @@ -0,0 +1,31 @@ +# s3-genindex + +Generate HTML directory indexes with file type icons and responsive design. + +## Install + +```bash +go install git.ipng.ch/ipng/s3-genindex/cmd/s3-genindex@latest +``` + +## Usage + +```bash +# Generate index.html in current directory +s3-genindex + +# Generate recursively with custom output +s3-genindex -r -o listing.html /path/to/dir + +# Exclude files by regex +s3-genindex -x "(build|node_modules|\.tmp)" +``` + +## Build + +```bash +make build +make test +``` + +See [docs/DETAILS.md](docs/DETAILS.md) for complete documentation. \ No newline at end of file diff --git a/docs/DETAILS.md b/docs/DETAILS.md new file mode 100644 index 0000000..de5972a --- /dev/null +++ b/docs/DETAILS.md @@ -0,0 +1,288 @@ +# s3-genindex - Detailed Documentation + +## Overview + +s3-genindex is a Go rewrite of the original Python genindex.py script.
