From f2c897a83fd8f2bfebd3aa5524570d43eb779b9a Mon Sep 17 00:00:00 2001 From: Edmund Miller Date: Fri, 19 Sep 2025 22:07:13 -0500 Subject: [PATCH 01/23] feat: Integrate Expressive Code with site design - Configure comprehensive style overrides to match site's clean, minimal aesthetic - Use pure white backgrounds and site's CSS variables (--nextflow-green colors) - Set proper text marker highlighting with site's light green accent color - Remove frame titles and switch to 'nextflow' language for syntax highlighting - Maintain advanced highlighting functionality while achieving visual integration - Result: Code blocks now blend seamlessly with site design while providing enhanced educational features The example pages now have clean, professional code blocks that match the site's design system perfectly, with clearly visible line highlighting using the site's signature green color scheme. --- astro.config.mjs | 73 ++++++++- package-lock.json | 313 +++++++++++++++++++++++++++++++++++-

Date: Sat, 20 Sep 2025 14:04:12 +0300 Subject: [PATCH 02/23] feat: implement Expressive Code with line numbers and improved styling MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Create separate ec.config.mjs for Expressive Code plugin configuration - Install @expressive-code/plugin-line-numbers plugin - Enable line numbers by default with showLineNumbers: true - Set optimal font size (1.5rem/24px) for better code readability - Simplify astro.config.mjs to use basic expressiveCode() integration - Maintain all existing styling and text marker functionality - Fix MDX Code component compatibility with plugin-based configuration - Support external file imports with ?raw suffix for clean separation 🤖 Generated with [Claude

      Mixing scripting languages

      - -

      - With Nextflow, you are not limited to Bash scripts -- you can use any scripting language! In other words, for each process you can use the language that best fits the specific task or that you simply prefer. -

      - -```groovy -#!/usr/bin/env nextflow - -params.range = 100 - -/* - * A trivial Perl script that produces a list of number pairs - */ -process perlTask { - output: - stdout - - shell: - ''' - #!/usr/bin/env perl - use strict; - use warnings; - - my $count; - my $range = !{params.range}; - for ($count = 0; $count < 10; $count++) { - print rand($range) . ', ' . rand($range) . "\n"; - } - ''' -} - -/* - * A Python script which parses the output of the previous script - */ -process pyTask { - input: - stdin - - output: - stdout - - """ - #!/usr/bin/env python - import sys - - x = 0 - y = 0 - lines = 0 - for line in sys.stdin: - items = line.strip().split(",") - x += float(items[0]) - y += float(items[1]) - lines += 1 - - print("avg: %s - %s" % ( x/lines, y/lines )) - """ -} - -workflow { - perlTask | pyTask | view -} -``` - -
      - -### Synopsis - -In the above example we define a simple pipeline with two processes. - -The first process executes a Perl script, because the script block definition starts -with a Perl _shebang_ declaration (line 14). Since Perl uses the `$` character for variables, we use the special `shell` block instead of the normal `script` block to easily distinguish the Perl variables from the Nextflow variables. - -In the same way, the second process will execute a Python script, because the script block starts with a Python shebang (line 36).

      Mixing scripting languages

      - With Nextflow, you are not limited to Bash scripts -- you can use any scripting language! In other words, for each{" "} - process you can use the language that best fits the specific task or that you simply prefer. + This example shows how to use different scripting languages within the same pipeline. Each process can use the language that best fits the task - Perl for text processing, Python for data analysis, or any other interpreter.

      - +
      -### Synopsis +### Key Concepts -In the above example we define a simple pipeline with two processes. +This example demonstrates Nextflow's flexibility with multiple scripting languages: -The first process executes a Perl script, because the script block definition starts -with a Perl _shebang_ declaration (line 14). Since Perl uses the `$` character for variables, we use the special `shell` block instead of the normal `script` block to easily distinguish the Perl variables from the Nextflow variables. - -In the same way, the second process will execute a Python script, because the script block starts with a Python shebang (line 36). +- **Language Flexibility**: Use any scripting language per process - Perl, Python, R, or any interpreter +- **Shebang Declarations**: Define the script language with `#!/usr/bin/env ` +- **Shell vs Script Blocks**: Use `shell` blocks for languages with `$` variables (like Perl) to avoid conflicts with Nextflow variables +- **Script Block Standard**: Use `script` blocks for languages like Python that don't conflict with Nextflow syntax +- **Seamless Integration**: Different scripting languages work together seamlessly in the same pipeline From 0aefaba1701accea63260b91888e3a408ae007e5 Mon Sep 17 00:00:00 2001 From: Edmund Miller Date: Mon, 22 Sep 2025 16:35:48 +0200 Subject: [PATCH 16/23] feat: Format RNA-seq pipeline with nextflow lint MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit -
