\nInstructions\n\n#### MacOS\n```\nbrew install slides\n```\n#### Arch\n```\nyay -S slides\n```\n#### Nixpkgs (unstable)\n```\nnix-env -iA nixpkgs.slides\n```\n#### Any Linux Distro running `snapd`\n```\nsudo snap install slides\n```\n#### Go\n```\ngo install github.com/maaslalani/slides@latest\n```\nFrom source:\n```\ngit clone https://github.com/maaslalani/slides.git\ncd slides\ngo install\n```\n\nYou can also download a binary from the [releases](https://github.com/maaslalani/slides/releases) page.\n\n
\n\n\n### Usage\nCreate a simple markdown file that contains your slides:\n\n````markdown\n# Welcome to Slides\nA terminal based presentation tool\n\n---\n\n## Everything is markdown\nIn fact, this entire presentation is a markdown file.\n\n---\n\n## Everything happens in your terminal\nCreate slides and present them without ever leaving your terminal.\n\n---\n\n## Code execution\n```go\npackage main\n\nimport \"fmt\"\n\nfunc main() {\n fmt.Println(\"Execute code directly inside the slides\")\n}\n```\n\nYou can execute code inside your slides by pressing ``,\nthe output of your command will be displayed at the end of the current slide.\n\n---\n\n## Pre-process slides\n\nYou can add a code block with three tildes (`~`) and write a command to run *before* displaying\nthe slides, the text inside the code block will be passed as `stdin` to the command\nand the code block will be replaced with the `stdout` of the command.\n\n```\n~~~graph-easy --as=boxart\n[ A ] - to -> [ B ]\n~~~\n```\n\nThe above will be pre-processed to look like:\n\n┌───┐ to ┌───┐\n│ A │ ────> │ B │\n└───┘ └───┘\n\nFor security reasons, you must pass a file that has execution permissions\nfor the slides to be pre-processed. You can use `chmod` to add these permissions.\n\n```bash\nchmod +x file.md\n```\n\n````\n\nCheckout the [example slides](https://github.com/maaslalani/slides/tree/main/examples).\n\nThen, to present, run:\n```\nslides presentation.md\n```\n\nIf given a file name, `slides` will automatically look for changes in the file and update the presentation live.\n\n`slides` also accepts input through `stdin`:\n```\ncurl http://example.com/slides.md | slides\n```\n\nGo to the first slide with the following key sequence:\n* g g\n\nGo to the next slide with any of the following key sequences:\n* space\n* right\n* down\n* enter\n* n\n* j\n* l\n* Page Down\n* number + any of the above (go forward n slides)\n\nGo to the previous slide with any of the following key sequences:\n* left\n* up\n* p\n* h\n* k\n* N\n* Page Up\n* number + any of the above (go back n slides)\n\nGo to a specific slide with the following key sequence:\n\n* number + G\n\nGo to the last slide with the following key:\n\n* G\n\n### Search\n\nTo quickly jump to the right slide, you can use the search function.\n\nPress /, enter your search term and press Enter \n(*The search term is interpreted as a regular expression. The `/i` flag causes case-insensitivity.*).\n\nPress ctrl+n after a search to go to the next search result.\n\n### Code Execution\n\nIf slides finds a code block on the current slides it can execute the code block and display the result as virtual text\non the screen.\n\nPress ctrl+e on a slide with a code block to execute it and display the result.\n\n### Pre-processing\n\nYou can add a code block with three tildes (`~`) and write a command to run\n*before* displaying the slides, the text inside the code block will be passed\nas `stdin` to the command and the code block will be replaced with the `stdout`\nof the command. Wrap the pre-processed block in three backticks to keep\nproper formatting and new lines.\n\n````\n```\n~~~graph-easy --as=boxart\n[ A ] - to -> [ B ]\n~~~\n```\n````\n\nThe above will be pre-processed to look like:\n\n```\n┌───┐ to ┌───┐\n│ A │ ────> │ B │\n└───┘ └───┘\n```\n\nFor security reasons, you must pass a file that has execution permissions\nfor the slides to be pre-processed. You can use `chmod` to add these permissions.\n\n```bash\nchmod +x file.md\n```\n\n### Configuration\n\n`slides` allows you to customize your presentation's look and feel with metadata at the top of your `slides.md`.\n\n> This section is entirely optional, `slides` will use sensible defaults if this section or any field in the section is omitted.\n\n```yaml\n---\ntheme: ./path/to/theme.json\nauthor: Gopher\ndate: MMMM dd, YYYY\npaging: Slide %d / %d\n---\n```\n\n* `theme`: Path to `json` file containing a [glamour\n theme](https://github.com/charmbracelet/glamour/tree/master/styles), can also\n be a link to a remote `json` file which slides will fetch before presenting.\n* `author`: A `string` to display on the bottom-left corner of the presentation\n view. Defaults to the OS current user's full name. Can be empty to hide the author.\n* `date`: A `string` that is used to format today's date in the `YYYY-MM-DD` format. If the date is not a valid\n format, the string will be displayed. Defaults to `YYYY-MM-DD`.\n* `paging`: A `string` that contains 0 or more `%d` directives. The first `%d`\n will be replaced with the current slide number and the second `%d` will be\n replaced with the total slides count. Defaults to `Slide %d / %d`.\n You will need to surround the paging value with quotes if it starts with `%`.\n\n#### Date format\n\nGiven the date _January 02, 2006_:\n\n| Value | Translates to |\n|--------|---------------|\n| `YYYY` | 2006 |\n| `YY` | 06 |\n| `MMMM` | January |\n| `MMM` | Jan |\n| `MM` | 01 |\n| `mm` | 1 |\n| `DD` | 02 |\n| `dd` | 2 |\n\n### SSH\n\nSlides is accessible over `ssh` if hosted on a machine through the `slides\nserve [file]` command.\n\nOn a machine, run:\n\n```\nslides serve [file]\n```\n\nThen, on another machine (or same machine), `ssh` into the port specified by\nthe `slides serve [file]` command:\n```\nssh 127.0.0.1 -p 53531\n```\n\nYou will be able to access the presentation hosted over SSH! You can use this\nto present with `slides` from a computer that doesn't have `slides` installed,\nbut does have `ssh`. Or, let your viewers have access to the slides on their\nown computer without needing to download `slides` and the presentation file.\n\n### Alternatives\n\n**Credits**: This project was heavily inspired by [`lookatme`](https://github.com/d0c-s4vage/lookatme).\n\n* [`lookatme`](https://github.com/d0c-s4vage/lookatme)\n* [`sli.dev`](https://sli.dev/)\n* [`sent`](https://tools.suckless.org/sent/)\n* [`presenterm`](https://github.com/mfontanini/presenterm)\n\n### Development\nSee the [development documentation](./docs/development)\n" }, { "path": "SECURITY.md", "content": "# Security Policy\n\n## Reporting a Vulnerability\n\nEmail [maas@lalani.dev](mailto:maas@lalani.dev)\n" }, { "path": "docs/development/README.md", "content": "# Development\n\nMake changes, and test them by running:\n```\nmake\n```\n\nThis will run `go run main.go examples/slides.md`, you can then ensure\neverything still works.\n\nIf you're adding a feature that requires a specific piece of markdown, you can\nadd a file with your test case into `examples/.md` and iterate on that file.\n\nEnsure tests are still passing\n```\nmake test\n```\n\n### Breaking Changes\nMost changes should be entirely backwards compatible.\nEnsure that `slides examples/slides.md` still works.\n\n### Codebase\nInitialization (command-line interface, defaults) happens in [`cmd/root.go`](../../cmd/root.go).\nInteraction (controls, input, output) happens in [`model.go`](../../internal/model/model.go)\nOptional configuration (e.g. `theme: dark`) can be added to [`meta.go`](../../internal/meta/meta.go)\n" }, { "path": "examples/ascii_slides.md", "content": "---\ntheme: ascii\n---\n\n# Welcome to Slides\nA terminal based presentation tool\n\n```go\npackage main\n\nimport \"fmt\"\n\nfunc main() {\n fmt.Println(\"Written in Go!\")\n}\n```\n\n---\n\n## Everything is markdown\nIn fact this entire presentation is a markdown file\n\n---\n\n# h1\n## h2\n### h3\n#### h4\n##### h5\n###### h6\n\n# Markdown components\nYou can use everything in markdown!\n* Like bulleted list\n* You know the deal\n\n1.
