FlowGraph 0.5.0

What's new in 0.5.0

Structs

Scripts can declare their own record types: My Script > Structs, then the fields in Details (name, type, default,
description).

• Make Point builds one from its fields, Break Point gives its fields, Set Point.X changes one field in place: the
  struct of the variable, or of the array element, it is connected to.
• A value, like an array: setting a variable or passing a struct to a function by value makes a copy.
• Fields of any type: numbers, strings, arrays, maps, the application's classes, other structs (a Contact with a Home that
  is a Point). A struct can hold itself only through an array or a map (Children: array<Tree>).
• Variables, local variables, function parameters and containers can be of a struct type (array<Contact>).
• Rename a struct or a field and every type and node that uses it follows; Find References lists them. A running script
  that is changed keeps its values field by field.
• The debugger shows the fields, and a watch reaches one (People[0].Name).
• Examples/Scripts/contacts.flow shows them at work.

Bytes

• bytes: raw data (the content of a file, a network message), one shared buffer that costs nothing to pass along.
  byte: a number from 0 to 255 that works where an int does.
• Nodes: Length, Byte At, Slice, Concat, Find, Starts With / Ends With; From Text / To Text (UTF-8; Valid says
  whether the bytes were UTF-8), To Hex / From Hex, To Base64 / From Base64, To Array / Make Bytes (array<byte>).
• Binary files: the FileSystem plugin has Read Bytes and Write Bytes.
• Examples/Scripts/bytes.flow shows them.

The editor

• Snap to grid makes links straight. A node made from a dragged pin goes level with it, a node moved alone snaps to its link
  when the link can be straight, and nodes moved together keep where they are to each other.
• View > Full Screen (Shift+Alt+Enter).
• Parameters: the type, container and key of a function's inputs and outputs (and of a struct's fields) look like combo
  boxes and open on one click.
• The window keeps the layout of its docks. A maximized window got other dock sizes at every start.
• Details no longer shows a variable, function or struct after it was deleted.
• On Linux, a right click while a link was being dragged left a dashed link behind.

Other changes

• Map nodes: Set Entry and Get Entry are now Add and Get Item, like the array nodes (Add adds the key or changes its
  value). Scripts made before keep working.
• flow no longer prints Execution Time after the script: the output is only what the script prints (the Now and
  Seconds Since Start nodes measure time where a script needs it).
• The texts are in the editor's 9 other languages (Persian reviewed, the others machine translations).

For plugin authors: the plugin interface changed (new kinds of values and types), so plugins built for 0.4 are refused (with
the reason): build them again against 0.5. Applications that use find_package(FlowGraph 0.4) ask for 0.5 now.

Downloads

• FlowGraph-0.5.0-windows-x64.zip: flow, flowstudio (Qt included) and the SDK: headers, libraries and the CMake
  package (find_package(FlowGraph): FlowGraph::Core, FlowGraph::ScriptEditor). Windows 10 or later, x64.
• FlowGraph-0.5.0-linux-x64.tar.gz: the same for Linux x64. It runs on distributions with glibc 2.28 or newer:
  RHEL / CentOS / Alma / Rocky 8 and 9, Debian 10, Ubuntu 20.04 and newer. flowstudio brings its Qt; the system
  needs the usual X11 libraries (for example xcb-util-cursor / libxcb-cursor0, libxkbcommon-x11).
• SHA256SUMS.txt: checksums of both.

Plugins are binary: build them against this release (the loader refuses a plugin made for another build, with the reason).

Licenses: the runtime (FlowGraphCore) and flow are MIT; the editor and flowstudio are GPL-3.0-only, as they are
built on KDDockWidgets (GPL). Qt is used under the LGPL-3.0. The texts are in each package (LICENSE, LICENSES/).
