File organization (click to show) Folders: | folder | contents | |:-------------|:--------------------------------------------------------------| | `bin` | server-side bin scripts (`xlsx.njs`) | | `bits` | raw source files that make up the final script | | `dist` | dist files for web browsers and nonstandard JS environments | | `misc` | miscellaneous supporting scripts | | `modules` | TypeScript source files that generate some of the bits | | `packages` | Support libraries and tools | | `test_files` | test files (pulled from the test files repository) | | `tests` | browser tests (run `make ctest` to rebuild) | | `types` | TypeScript definitions and tests |
After cloning the repo, running `make help` will display a list of commands. ## OS-Specific Setup import Tabs from '@theme/Tabs'; import TabItem from '@theme/TabItem'; The MacOS/Linux workflow works in WSL. Initial setup is involved: 1) Install mercurial and subversion. ```bash # Install support programs for the build and test commands sudo add-apt-repository ppa:mercurial-ppa/releases sudo apt-get update sudo apt-get install mercurial subversion sudo add-apt-repository --remove ppa:mercurial-ppa/releases ``` 2) Install NodeJS ```bash # Install bootstrap NodeJS and NPM within the WSL curl -fsSL https://deb.nodesource.com/setup_16.x | sudo -E bash - sudo apt-get install -y nodejs # CLOSE AND REOPEN SHELL BEFORE CONTINUING # Switch to `n`-managed NodeJS sudo npm i -g n sudo n 16 ``` 3) Build and install a version of Git with proper SSL support: ```bash # Git does not support OpenSSL out of the box, must do this curl -LO https://github.com/paul-nelson-baker/git-openssl-shellscript/raw/main/compile-git-with-openssl.sh chmod +x compile-git-with-openssl.sh ./compile-git-with-openssl.sh ``` (instructions continued in the MacOS/Linux part) Initial setup: 0) Ensure mercurial, subversion, and NodeJS are installed. The WSL instructions will have installed these dependencies, so WSL users can skip to step 1. :::note [The official NodeJS site](https://nodejs.org/en/download/) provides installers for "LTS" and "Current" releases. The "LTS" version should be installed. ::: Mercurial and Subversion: On Linux, install using the system package manager. Debian and Ubuntu use `apt`: ```bash sudo apt-get install mercurial subversion ``` Other Linux distributions may use other package managers.
Steam Deck (click to show) Desktop Mode on the Steam Deck uses `pacman`. It also requires a few steps. 0) Switch to Desktop mode and open `Konsole` 1) Set a password for the user by running `passwd` and following instructions. 2) Disable read-only mode: ```bash sudo steamos-readonly disable ``` (When prompted, enter the password assigned in step 1) 3) Configure keyring: ```bash echo "keyserver hkps://keyserver.ubuntu.com" >> /etc/pacman.d/gnupg/gpg.conf sudo pacman-key --init sudo pacman-key --populate sudo pacman-key --refresh-keys ``` 4) Install dependencies: ```bash yay -S base-devel mercurial subversion ```
On MacOS, install using Homebrew. 0) Open a terminal window and install Homebrew: ```bash /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" ``` 1) Close the window, open a new terminal window, and disable analytics: ```bash brew analytics off ``` To confirm analytics are disabled, run ```bash brew analytics state ``` It should print `Analytics are disabled.` 2) Install Mercurial and Subversion: ```bash brew install mercurial subversion ``` 1) Install NodeJS modules for building the scripts ```bash # Install dev dependencies npm install # Install global dependencies sudo npm i -g mocha@2.5.3 voc @sheetjs/uglify-js ``` :::note Older Versions of Dependencies Some of the dependencies are wildly out of date. While SheetJS aims to run in older versions of NodeJS and browsers, some libraries have chosen to break backwards compatibility. The specific versions are used because they are known to work and known to produce consistent results. ::: 2) Initialize the test files: ```bash make init ``` This step may take a while as it will be downloading a number of test files. 3) Run a short test, then run a build ```bash # Short test make test_misc # Full Build cd modules; make; cd .. make dist ``` 4) (For Deno testing) Install Deno: ```bash curl -fsSL https://deno.land/install.sh | sh ``` 5) (For Bun testing) Install Bun: ```bash curl https://bun.sh/install | bash ``` ## Development The `xlsx.js` and `xlsx.mjs` files are constructed from the files in the `bits` subfolder. The build script (run `make`) will concatenate the individual bits to produce the scripts. To produce the dist files, run `make dist`. The dist files are updated in each version release and *should not be committed between versions*. ## Tests The `test_misc` target runs the targeted feature tests. It should take 5-10 seconds to perform feature tests without testing against the full test battery. New features should be accompanied with tests for the relevant file formats. For tests involving the read side, an appropriate feature test would involve reading an existing file and checking the resulting workbook object. If a parameter is involved, files should be read with different values to verify that the feature is working as expected. For tests involving a new write feature which can already be parsed, appropriate feature tests would involve writing a workbook with the feature and then opening and verifying that the feature is preserved. For tests involving a new write feature without an existing read ability, please add a feature test to the kitchen sink `tests/write.js`.
