Bug

File > Open Recent and New Group > Link Recent replace/remove strings in file paths and activate mnemonic accelerator keys.

This means that on GNU/Linux the path /tmp/_foo_&_bar_.slvs is showed as /tmp/foo_bar.slvs.

settings.json

{
  "RecentFile_0":"\/tmp\/_foo_&_bar_.slvs"
}

before

Proposed solution

Add mnemonics argument to Platform::Menu::AddItem to treat as raw text label's mnemonic accelerator keys when it is false (src/platform/gui.h).

New pure virtual function Platform::Menu::AddItemRaw which treats as raw text label's mnemonic accelerator keys (src/platform/gui.h).

AddItemRaw doesn't replace/remove label's text (i.e. guigtk.cpp '&' -> '_'), nor it activates mnemonic accelerator keys.

after

Caveats

Solution tested only on Gentoo GNU/Linux.

The code in src/platform/guiwin.cpp and src/platform/guimac.mm isn't tested and may require amendments.

Does NegateMnemonics escape mnemonic accelerator keys correctly (src/platform/guiwin.cpp)?

Not sure if AddItemRaw in guiwin.cpp shall allocate a buffer before assigning it to mii.dwTypeData. Also, does SetMenuItemInfoW operate as expected updating the menu item's label?

Can someone review the code, please?

I would prefer if you added an argument to AddItem, bool mnemonics = true, instead. This would lead to less code duplication. E.g. on macOS there are no mnemonics in the first place.

New pure virtual function Platform::Menu::AddItemRaw which treats as
raw text label's mnemonic accelerator keys (src/platform/gui.h).

"File > Open Recent" and "New Group > Link Recent" now list paths in
their integrity: AddItemRaw doesn't replace/remove label's text (i.e.
guigtk.cpp '&' -> '_'), nor it activates mnemonic accelerator keys.

Ok, I'll provide an alternative way as new commit. Then, if you approve it, let's squash the commits.

Add mnemonics argument to Platform::Menu::AddItem (src/platform/gui.h)
to treat as raw text label's mnemonic accelerator keys when false.

"File > Open Recent" and "New Group > Link Recent" now list paths in
their integrity.  With AddItem's mnemonics argument set to false, no
label's text is replaced/removed (i.e. guigtk.cpp '&' -> '_'), nor
mnemonic accelerator keys are activated.

I see... I misinterpreted your suggestion...

I think unless you put the mnemonics argument after onTrigger the default value for it is quite pointless.

I'm sorry, what I got was "do not use a default value for mnemonics"... So, I saw no reason to put mnemonics after onTrigger...

Thanks for the bug report and the patch. Fixed in ce0b130.

You're welcome. Thanks for fixing the master branch!
