If there is a pre-existing file with this name, make sure it\nis safe, when it is overwritten/deleted, or change the current directory (the script itself\ncan be run from anywhere).\n\n```sh \nv download -RD https://raw.githubusercontent.com/vlang/v-analyzer/main/install.vsh\n```\n\nNote: if you get messages about `response does not start with HTTP/`, try going to the\nmain V repository, then do `./v -d use_openssl cmd/tools/vdownload.v` .\nAfter that, retry the same command:\n```sh \nv download -RD https://raw.githubusercontent.com/vlang/v-analyzer/main/install.vsh\n```\n\n## Pre-built binaries\n\nYou can download pre-built binaries from the [release page](https://github.com/vlang/v-analyzer/releases).\nCurrently, we provide binaries for Linux (x64), macOS (x64 and ARM), and Windows (x64).\n\n## Building from source\n\n> [!NOTE]\n> This repository uses Git submodules.\n> In practice, this means that you either have to:\n>\n> ```sh\n> git clone --filter=blob:none --recursive --shallow-submodules https://github.com/vlang/v-analyzer\n> ```\n>\n> ... or, if you used just `git clone https://github.com/vlang/v-analyzer`, you can execute below\n> inside your local `v-analyzer` clone:\n>\n> ```sh\n> git submodule init && git submodule update\n> ```\n>\n> If you do not do either, the symptom is that when you try to build v-analyzer, you will get a\n> C compiler message, about `lib.c not found`\n\n> [!TIP]\n> On Windows, use GCC for building, as TCC can run into some issues.\n\nUpdate V to the latest version:\n\n```bash\nv up\n```\n\nYou can build a debug or release version of the binary.\nThe debug version will be slower, but faster to compile.\n\n```bash\nv build.vsh debug\n```\n\n```bash\nv build.vsh release\n```\n\nThe compiled binary will be located in the `bin/` folder.\n\n## Setup\n\nAdd the `bin/` folder to your `$PATH` environment variable to make the `v-analyzer` command easily\naccessible.\n\nYou can also specify the path to the binary in your VS Code settings:\n\n```json\n{\n\t\"v-analyzer.serverPath\": \"/path/to/v-analyzer/bin/v-analyzer\"\n}\n```\n\n> **Note**\n> Restart VS Code after changing the settings or PATH.\n\n### Config\n\nv-analyzer is configured using global or local config.\nThe global config is located in `~/.config/v-analyzer/config.toml`, changing it will affect all\nprojects.\n\nA local config can be created with the `v-analyzer init` command at the root of the project.\nOnce created, it will be in `./.v-analyzer/config.toml`.\nEach setting in the config has a detailed description.\n\nPay attention to the `custom_vroot` setting, if v-analyzer cannot find where V was installed, then\nyou will need to specify the path to it manually in this field.\n\n## Updating\n\nTo update `v-analyzer` to the latest version, run:\n\n```bash\nv-analyzer up\n```\n\nYou can also update to a nightly version:\n\n```bash\nv-analyzer up --nightly\n```\n\n> **Note**\n> In the nightly version you will get the latest changes, but they may not be stable!\n\n## VS Code extension\n\nThe VS Code extension is available via the [VS Code Marketplace](https://marketplace.visualstudio.com/items?itemName=VOSCA.vscode-v-analyzer).\nThe source code for extension is contained in the [`editors/code`](https://github.com/vlang/v-analyzer/tree/main/editors/code) folder of this repository.\n\n## NVIM LSP / Mason\n\nFor Neovim users, v-analyzer is available via [nvim-lspconfig](https://github.com/neovim/nvim-lspconfig/blob/master/doc/server_configurations.md#v_analyzer) plugin.\nIt is part of the [mason registry](https://mason-registry.dev/registry/list#v-analyzer) and could be installed with both Neovim plugins:\n- [mason.nvim](https://github.com/williamboman/mason.nvim) with `:MasonInstall v-analyzer` command\n- [mason-lspconfig.nvim](https://github.com/williamboman/mason-lspconfig.nvim) with `:LspInstall` command\n\n## Authors\n\n- `jsonrpc`, `lsp`, `tree_sitter_v` modules written initially by\n [VLS authors](https://github.com/vlang/vls) and after that in 2023 it was modified by the\n [VOSCA](https://github.com/vlang-association).\n\n## Thanks\n\n- [VLS](https://github.com/vlang/vls) authors for the initial Language Server implementation!\n- [vscode-vlang](https://github.com/vlang/vscode-vlang) authors for the first VS Code extension!\n- [rust-analyzer](https://github.com/rust-lang/rust-analyzer) and [gopls](https://github.com/golang/tools/tree/master/gopls) for the inspiration!\n- [Tree-sitter](https://github.com/tree-sitter/tree-sitter) authors for the cool parsing library!\n\n## License\n\nThis project is under the **MIT License**.\nThe full license text can be found in the

First of all, make sure you have the latest version of V installed.\n If you are unsure, run `v up` to update.\n\n2. Now let's install VS Code **v-analyzer** extension:\n\n 1. Open the command palette with `Ctrl+Shift+P` or `Cmd+Shift+P`\n 2. Select `Install Extensions` and choose `v-analyzer`.\n\n You can also install the extension manually:\n\n 1. Select `Install from VSIX...`\n 2. Choose pre-built VSIX file from this folder or build it yourself\n\n After installation, restart VS Code.\n\n3. Open any project that contains files with `.v` extension.\n The extension should automatically activate.\n Upon activation, the extension will try to find `v-analyzer` server, which\n is the heart of the extension and provides all the smart features.\n\n4. Since `v-analyzer` server is not installed\n (unless you installed it in advance and added it to PATH, in which case you\n can skip this step), the extension will prompt you to install it.\n Click `Install` and wait for the installation to complete.\n\n5. After installing `v-analyzer` server, the extension will prompt you to\n restart the `v-analyzer` server.\n Click `Yes` and wait for the restart to complete.\n\n6. When `v-analyzer` server is successfully restarted,\n it will start to analyze your project as well as the V standard library.\n\n7. Note that if `v-analyzer` server cannot find where the V standard library\n is stored, an error will be shown.\n\n In this case, follow the instructions in the error and specify the path to\n the V source code folder in the `custom_vroot` field.\n\n > **Note**\n > You need to specify the folder where all the V sources are stored\n > (e.g. `C:\\v\\` or `/home/user/v/` and not the folder with the standard library\n > (e.g. `C:\\v\\vlib` or `/home/user/v/vlib`)!\n > After making changes, restart `v-analyzer` using the `v-analyzer: Restart server`\n > command in the command palette.\n\n8. If the server was able to find all the necessary things, then after a while the\n indexing will end, and you will be able to use all the features of `v-analyzer`.\n\n > **Note**\n > Indexing can take up to 30 seconds on weak machines, but this is only\n > done on the first run; then the indexes will be loaded from the cache.\n\nYou are ready to code in V! šŸŽ‰\n\n## Manual Setup\n\nYou can install ``v-analyzer`` server manually:\nClone the\n[`v-analyzer`](https://github.com/vlang/v-analyzer)\nrepository, build it and specify the path to the compiled binary.\n\n```json\n{\n \"v-analyzer.serverPath\": \"path/to/v-analyzer\"\n}\n```\n\n## Auto save\n\n`v-analyzer` uses `v` compiler to analyze code.\nIt calls it every time a file is saved, so you can set up auto-save to get real-time\nfeedback.\n\n```json\n{\n \"files.autoSave\": \"afterDelay\",\n \"files.autoSaveDelay\": 300\n}\n```\n\n## Semantic tokens\n\nWith highlighting based on TextMate grammar, v-analyzer provides semantic\nhighlighting, which allows you to highlight fields, variables, parameters and other\nelements as different entities.\n\nTo enable semantic highlighting, make sure the `editor.semanticHighlighting.enabled`\nsetting is set to `true` in the VS Code settings.\n\nIn the settings, you can also specify colors for each entity type:\n\n```json\n{\n \"editor.semanticTokenColorCustomizations\": {\n \"[Theme Name]\": {\n \"rules\": {\n \"namespace\": \"#AFBF7E\",\n \"parameter\": \"#B189F5\",\n \"decorator\": \"#DEBC7E\",\n \"typeParameter\": \"#B189F5\",\n \"enumMember\": \"#72CFD6\",\n \"*.global\": \"#A9B7C6\",\n \"function\": \"#FFC66D\",\n \"*.mutable\": {\n \"underline\": true\n }\n }\n }\n }\n}\n```\n\nSee\n[all available entity types](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#semanticTokenTypes)\nin the LSP specification.\n\n## Building from source\n\n```bash\nnpm install\nnpm run package\n```\n\n## License\n\nThis project is under the **MIT License**.\nSee the\n[LICENSE](https://github.com/vlang/v-analyzer/blob/main/editors/code/LICENSE)\nfile for the full license text.\n" }, { "path": "editors/code/docs/troubleshooting.md", "content": "# Troubleshooting\n\nIf you suspect that the V extension is not working correctly, please follow the\ntroubleshooting steps below.\n\nTODO\n" }, { "path": "editors/code/languages/v-language-configuration.json", "content": "{\n\t\"comments\": {\n\t\t\"lineComment\": \"//\",\n\t\t\"blockComment\": [\"/*\", \"*/\"]\n\t},\n\t\"folding\": {\n\t\t\"markers\": {\n\t\t\t\"start\": \"^\\\\s*//\\\\s*#?region\\\\b\",\n\t\t\t\"end\": \"^\\\\s*//\\\\s*#?endregion\\\\b\"\n\t\t}\n\t},\n\t\"brackets\": [\n\t\t[\"{\", \"}\"],\n\t\t[\"[\", \"]\"],\n\t\t[\"(\", \")\"]\n\t],\n\t\"autoClosingPairs\": [\n\t\t[\"{\", \"}\"],\n\t\t[\"[\", \"]\"],\n\t\t[\"(\", \")\"],\n\t\t[\"\\\"\", \"\\\"\"],\n\t\t[\"'\", \"'\"]\n\t],\n\t\"surroundingPairs\": [\n\t\t[\"{\", \"}\"],\n\t\t[\"[\", \"]\"],\n\t\t[\"(\", \")\"],\n\t\t[\"\\\"\", \"\\\"\"],\n\t\t[\"'\", \"'\"]\n\t]\n}\n" }, { "path": "editors/code/languages/vmod-language-configuration.json", "content": "{\n\t\"comments\": {\n\t\t\"lineComment\": \"//\",\n\t\t\"blockComment\": [\"/*\", \"*/\"]\n\t},\n\t\"folding\": {\n\t\t\"markers\": {\n\t\t\t\"start\": \"^\\\\s*//\\\\s*#?region\\\\b\",\n\t\t\t\"end\": \"^\\\\s*//\\\\s*#?endregion\\\\b\"\n\t\t}\n\t},\n\t\"brackets\": [\n\t\t[\"{\", \"}\"],\n\t\t[\"[\", \"]\"],\n\t\t[\"(\", \")\"]\n\t],\n\t\"autoClosingPairs\": [\n\t\t[\"{\", \"}\"],\n\t\t[\"[\", \"]\"],\n\t\t[\"(\", \")\"],\n\t\t[\"\\\"\", \"\\\"\"],\n\t\t[\"'\", \"'\"]\n\t],\n\t\"surroundingPairs\": [\n\t\t[\"{\", \"}\"],\n\t\t[\"[\", \"]\"],\n\t\t[\"(\", \")\"],\n\t\t[\"\\\"\", \"\\\"\"],\n\t\t[\"'\", \"'\"]\n\t]\n}\n" }, { "path": "editors/code/media/welcome.css", "content": "/*---------------------------------------------------------\n * Copyright 2020 The Go Authors.

'fn foo() { println(\"Hello, World!\") }'\n// res2 = p.parse_code_with_tree(code2, res.tree)\n// println(res2.tree\n// }\npub fn (mut p Parser) parse_code_with_tree(code string, old_tree

A V string is\n also slightly larger than the equivalent C string because\n the V string also has an integer length attached.\n\n This tradeoff is made, since V strings are created just *once*,\n but potentially used *many times* over their lifetime.\n\n The V string implementation uses a struct, that has a .str field,\n which points to a C style 0 terminated memory block. Although not\n strictly necessary from the V point of view, that additional 0\n is *very useful for C interoperability*.\n\n The V string implementation also has an integer .len field,\n containing the length of the .str field, excluding the\n terminating 0 (just like the C's strlen(s) would do).\n\n The 0 ending of .str, and the .len field, mean that in practice:\n a) a V string s can be used very easily, wherever a\n C string is needed, just by passing s.str,\n without a need for further conversion/copying.\n\n b) where strlen(s) is needed, you can just pass s.len,\n without having to constantly recompute the length of s\n *over and over again* like some C programs do. This is because\n V strings are immutable and so their length does not change.\n\n Ordinary V code *does not need* to be concerned with the\n additional 0 in the .str field. The 0 *must* be put there by the\n low level string creating functions inside this module.\n\n Failing to do this will lead to programs that work most of the\n time, when used with pure V functions, but fail in strange ways,\n when used with modules using C functions (for example os and so on).\n*/\npub struct string {\npub:\n\tstr &u8 = 0 // points to a C style 0 terminated string of bytes.\n\tlen int // the length of the .str field, excluding the ending 0 byte.
