🦕 Enhanced Deno commands

dxf, dxi, dxr, and dxx

Fixes…

formatter (dxf)

automatically runs dprint fmt if dprint is available and a config is found in the main repo directory o/w runs deno fmt

installer (dxi)

  • installs command scripts with an enhanced shim

    • command line expansion enhancement
      • enables automated, bash-like command line expansion (including full brace and advanced glob expansion) for WinOS platforms; pass-through for non-Windows platforms
      • when using the ‘xProcess’ library, enables scripts to more accurately determine the their invocation text allowing them to show accurate help and examples
    • blocks the annoying “Terminate batch job (Y/N)?” console question when using CTRL-C to interrupt the script

  • [WIP] can revise current shims, adding enhanced-shim functionality

    • prototypes for shim revision are contained in the ‘tools’ directory

runner (dxr)

  • runs scripts with the same command line expansion enhancements as dxi

  • [WIP]

    • automatically run dexter / XTR files
    • automatically set requested permissions
      • warn when setting without a CLI specification
    • can run distant scripts from the command line
      • like dpx but also searches within additional directories (‘src’, …)
      • can also install the remote script with an ‘–install’ flag

integrator (dxx)

  • [WIP]

dexter / xtr

  • [WIP]

Installation of Tools

# `dxi`
deno install -A "https://deno.land/x/dxx@v0.0.14/src/dxi.ts"
#
dxi -A "https://deno.land/x/dxx@v0.0.14/src/dxf.ts"
dxi -A "https://deno.land/x/dxx@v0.0.14/src/dxr.ts"
# WIP: dxi .../dxx
#...or (via CDN, with optional version/version-range/latest/commit support)...
# dxi -A "https://cdn.jsdelivr.net/gh/rivy/deno.dxx@v0.0.14/src/dxf.ts" // v0.0.14
# dxi -A "https://cdn.jsdelivr.net/gh/rivy/deno.dxx@COMMIT/src/dxf.ts"  // commit

Using the ‘xProcess’ library

Solely using dxr (after installation with dxi) as a script runner will perform bash-like argument expansion for the target script while preserving correct quote semantics for both double and single quoted arguments. Additional functionality requires use of the ‘xProcess’ library in coordination with either an enhanced runner, such as dxr, an enhanced shim (provided by installation with dxi), or using FFI (currently [as of 2022-01-01] requiring the use of --unstable).

Comparisons of eg\args.ts (using ‘xProcess’) vs args-naive.ts (without ‘xProcess’, using only deno built-ins) in various scenarios…

C:> ::# `deno`-only support => no expansion and uneven quote support with loss of quote context
C:> deno run -A eg/args-naive.ts '*' * "*"
'*' * *

C:> ::# `deno` for scripts using 'xProcess' => bash-like expansion, but broken preservation of quoted arguments
C:> deno run -A eg/args.ts '*' * "*"
* bench CHANGELOG.mkd eg LICENSE README.md src tests tools tsconfig.json VERSION bench CHANGELOG.mkd eg LICENSE README.md src tests tools tsconfig.json VERSION

C:> ::# `dxr` => bash-like expansion with preservation of quoted arguments
C:> dxr eg/args-naive.ts '*' * "*"
* bench CHANGELOG.mkd eg LICENSE README.md src tests tools tsconfig.json VERSION *

C:> ::# `dxr` => bash-like expansion with preservation of quoted arguments; better `$0` functionality available
C:> dxr eg/args.ts '*' * "*"
* bench CHANGELOG.mkd eg LICENSE README.md src tests tools tsconfig.json VERSION *

Fully capable, completely self-contained, executable binaries can be built from scripts which use the ‘xProcess’ library by compiling them with the --allow-all and --unstable flags. For example, using deno compile -A --unstable eg/args.ts (from the main project directory, on the WinOS platform) will produce a binary args.exe which contains all the enhanced argument functionality and requires no extra support. The resultant args.exe binary may be moved to any other WinOS platform and executed with full fidelity.
