Open a non-existent path as a new empty buffer - #89
Conversation
`resolveStartupTarget` (cli/argv.ts) and `DocumentManager.openDocument` (core/buffer/documentManager.ts) both used to treat a missing file the same as any other stat/read failure. Now an ENOENT specifically opens a new, empty, non-dirty document instead of failing, so `tecode README2.md` on a non-existent path opens an editable buffer and saving it creates the file — matching what saveNow already supported. argv.ts additionally refuses to treat the path as new when its parent directory doesn't exist or the argument is directory-shaped (trailing slash), since a CLI entry point can give a clearer, earlier warning for those than a silently-opened empty editor. DocumentManager stays unconditional on ENOENT since it's a shared, lower-level primitive; a missing-parent path there still gets a clear error, just at save() time. Every non-ENOENT failure (EACCES, EIO, ...) keeps rejecting and reporting exactly as before.

- Line 111: Update the trailing-separator check in the argv parsing logic so
backslash is treated as a directory separator only when process.platform is
"win32"; on POSIX, retain only the forward-slash check so names such as draft\
remain valid new-file paths. Add a regression test covering opening a new file
with a trailing backslash on POSIX.

Uh oh!
There was an error while loading. Please reload this page.
The directory-shaped guard rejected any path ending in `/` or `\`, but
`\` is a separator only on Windows. On POSIX it is an ordinary filename
character: `path.resolve("/tmp", "draft\\")` gives `/tmp/draft\`, whose
dirname is `/tmp` — not a directory named `draft`. So `tecode 'draft\'`
named a perfectly valid not-yet-created file, and the guard warned and
fell back to cwd instead of opening it.
`/` still ends the check on every platform; `\` now only does on win32.
Mutation-verified: restoring the platform-blind check fails the new
POSIX regression test, which is skipped on Windows where the old
behaviour is the correct one.

fix#88
tecode README2.mdwhere the file does not exist showedNo editor open.. It now opens an empty in-memory buffer, and saving creates the file.The save path was already done
documentManager.ts'ssaveNowalready treats anENOENTfrom its pre-writestatas "first save of a new file", continuing with the default mode and aborting only on other stat failures. Nothing there needed changing — the gap was entirely on the open side, in two places:cli/argv.ts'sresolveStartupTargetcaught everystatfailure, warned, and returned{ workspaceRoot: cwd }with noinitialFilePath, so nothing was ever opened.buffer/documentManager.ts'sopenDocumentreported and rethrew for every failure without distinguishingENOENT.Both now branch on
ENOENTonly.EACCESmust not become an empty bufferEvery other error code —
EACCES,EIO, and the rest — keeps today's reject-and-report behaviour. Silently opening a permission-denied file as an empty buffer is worse than the bug being fixed: the user would then "save" over a file they were never allowed to read.Both guards are mutation-verified. Neutralising the
documentManagerguard fails its EACCES test withExpected promise that rejects / Received promise that resolved; neutralising theargvguard fails its own.The implementer found that the first version of the argv EACCES test passed even under mutation, because its fake
statthrew unconditionally on every call and so masked the bug. It was tightened to let the parent-directory stat succeed while only the target path fails, after which it fails under mutation and passes with the fix.Design decisions
Missing parent directory — split by layer, deliberately.
resolveStartupTargetopens as new only whendirname(resolved)exists and is a directory, otherwise keeping today's warning: a CLI entry point can name the exact typo'd path immediately, and a deep typo silently opening an editor is harder to diagnose.openDocumentstays unconditional onENOENT— it is the shared lower-level primitive extensions also reach throughtecode.workspace.openDocument, so it stays simple, and a genuinely broken path still produces a clear error, just deferred tosave(). Pinned by a test: openingno-such-parent/deep.txtsucceeds as empty, thensave()fails with an error containingENOENT,path === uri, anddirtystilltrue.Trailing slash. Checked on the original argv token, before
path.resolvenormalises the separator away.tecode newdir/on a non-existentnewdiralways warns and never opens as a file.The new buffer starts non-dirty — but this does not mean what I assumed. I expected that a non-dirty buffer would make
save()a no-op, so opening a non-existent file and saving without editing would create nothing. That is wrong:saveNownever gates ondirtyat all — a pre-existing property unrelated to this change — so it always performs the write. Callingsave()on a document nobody typed into does create an empty file.What
dirty: falseactually buys is narrower: no save-changes prompt on quit for an untouched tab, and no autosave write. The test asserting this is named and commented for the real behaviour rather than the assumed one, so a future reader does not re-derive the wrong model.Tests
8 new tests. The load-bearing one is a real-filesystem end-to-end case in
main.test.tscoveringresolveStartupTarget→buildAssemblyRoot/runDeferredPhase→ edit →save()→ the real file on disk with the expected content — the argv resolution is inside the path under test, not stubbed around.Validation
