env-agree

Report when the environment variables that decide where tools read and write point at different places.

disagree: HOME and USERPROFILE: HOME=D:\sandbox\home but USERPROFILE=C:\Users\a
ok: TEMP and TMP: TEMP=C:\Users\a\AppData\Local\Temp

The problem it exists for

Programs do not agree on which variable to trust. Git reads HOME, Windows APIs read USERPROFILE, and npm uses APPDATA unless NPM_CONFIG_PREFIX overrides it. Sandboxes, containers and environment managers redirect some of these and not others. The symptom is "I changed the config and nothing happened", because the program you configured and the program you ran are reading two different directories.

env-agree compares the pairs that cause that, and says nothing when they agree.

Install

npm install env-agree

Node 18 or newer. No dependencies.

Use

env-agree

Exit code 0 when every pair agrees (or there was nothing to compare), 1 when at least one pair points at different places. Unset variables are skipped, not reported as failures.

The checks:

• HOME against USERPROFILE
• TEMP against TMP
• NPM_CONFIG_PREFIX against the prefix npm would compute from APPDATA
• NPM_CONFIG_CACHE against the cache npm would compute from LOCALAPPDATA
